"Why Do Some Custom Abutments Cause Problems?"
— Tribocorrosion, Surface Contamination, and Titanium Stability in the Era of Digital Implants
With the advancement of digital dentistry and CAD/CAM workflows, custom abutment fabrication has become a core workflow in dental technology. In particular, as intraoral scanners (IOS), guided surgery, and full digital workflows spread, the market for titanium premilled blanks and CAD/CAM custom abutments is growing rapidly, and the finishing quality and machining precision achieved by dental technicians have become increasingly important factors in long-term implant stability.

However, recurring problems such as screw loosening, peri-implant inflammation, connection wear, and component fracture continue to be reported in recent clinical practice, and some cases cannot be explained by patient factors or maintenance alone. In particular, the implant-abutment interface is a structure where repeated occlusal loading, saliva, bacterial biofilm, and micromotion coexist, meaning it may be continuously exposed to a tribocorrosion (friction + corrosion) environment over the long term.

This lecture will go beyond simply "fabricating a well-fitting custom abutment" and focus on surface engineering issues that can arise in actual digital lab workflows, including the quality and impurity of raw titanium material, premilled blank and OEM quality control, CNC machining quality, bur and metallic contamination, APC cleaning and acid treatment (HF), anodizing and oxide layer stability, and polishing quality, surface roughness, tribocorrosion, and titanium particle release.

It will also connect concepts reported in recent papers — such as titanium ion release, microgap and interface wear, surface roughness and biofilm, corrosion and peri-implant inflammation, titanium particles and inflammatory response — to actual lab workflows, and consider together what dental technicians should manage to ensure the long-term tissue stability of custom abutments.

As the digital era progresses, what matters more than simple CAD design may in fact be actual titanium surface quality and finishing precision. It is hoped that this lecture will serve as an opportunity to share a new perspective on custom abutment fabrication and a deeper consideration of long-term implant stability.

Intraoral scanners are no longer optional but essential equipment, yet many users still experience variation in results depending on their skill level, and repeated errors and rescanning have become routine in Full Arch and Full Mouth scans. This lecture's core goal is to reduce this inefficiency and present a "reproducible scanning strategy" that does not depend on skill level.

First, the basic principles of intraoral scanning and the theory behind data acquisition methods will be analyzed not as mere conceptual explanations but in connection with the structural causes of actual errors. By understanding the fundamental reasons why data breaks off in certain areas and why errors grow larger as scans accumulate, this lecture aims to present a logic-based scanning approach rather than simple tricks.

Next, empirical know-how known only to experienced practitioners will be organized and shared in detail, including standardized scan path settings and error-minimization strategies that allow beginners to reproduce the same results. In particular, practical scanning strategies and remedies for minimizing cumulative error and data distortion in Full Arch and Full Mouth scans will be presented, centered on real case studies.

The lecture also goes beyond simply using scan data to emphasize "scan analysis ability" — the capacity to judge and improve data accuracy on one's own. By presenting objective criteria for determining which scans are reliable data and which require rescanning, it will share methods for reducing unnecessary corrections and remakes.

Finally, the overall Full Mouth digital workflow based on intraoral scan data will be summarized together with real application cases, presenting practical strategies to eliminate bottlenecks and maximize efficiency across the entire process from scanning to design to fabrication. This lecture will go beyond simple equipment usage to offer clear answers for users whose goal is "scanning that doesn't fail."

This lecture introduces a "minimal-visit complete denture fabrication system" that maximizes satisfaction for both patients and clinicians in a rapidly changing digital dentistry environment. Conventional methods have had the limitation of accumulating error through complex impression-taking and multiple try-in stages. To overcome this, the system uses an innovative tool called the JB Tray to introduce a workflow that completes anatomical impression-taking, vertical dimension of occlusion (VDO) determination, and centric relation (CR) recording all in a single first visit.

Based on the impressions obtained this way, the lecture focuses on an "esthetic tooth arrangement method." Beyond simple functional restoration, it presents an anterior arrangement guide that harmonizes with the patient's facial appearance.

Even with a minimal number of visits, this approach reduces communication errors between the lab and the clinic and offers a practical solution for improving the quality of the final prosthesis.

Development of a Digital-Technology-Based Clear Aligner and Nano-Optical Sensor System for Measuring Orthodontic Force

The introduction of 3D printing technology has made it possible for modern dentistry to fabricate personalized clear aligners. However, conventional 3D-printed resin materials have fundamental limitations: low mechanical strength, degradation of material properties with long-term use, and the absence of real-time monitoring of orthodontic force. This lecture addresses three innovative technologies designed to solve these problems in an integrated way, aiming to build a next-generation smart aligner system that will lead the era of precision dentistry.

Topic 1: Metal Wire Integration Technology
Metal wire integration technology dramatically improves the mechanical performance of 3D-printed clear aligners. By integrating nickel-titanium wire into the aligner structure and applying advanced surface treatment techniques such as sandblasting and acid etching, wire-resin bond strength is improved by 40–60%. This enhances not only the static strength of the aligner but also its dynamic mechanical properties, achieving more stable and predictable delivery of orthodontic force.

Topic 2: Stability Evaluation in an Artificial Oral Environment
Evaluating material stability in an artificial oral environment provides scientific evidence for clinical decision-making. Two commercial 3D-printed resins (Graphy TA-28 and LuxCreo DCA) were aged for 28 days in artificial saliva at 37°C, matching body temperature, after which surface morphology, roughness, optical properties, mechanical properties, thermal properties, and cytotoxicity were comprehensively evaluated. The results showed that artificial aging significantly affected mechanical properties, optical properties, and surface roughness, while the glass transition temperature (Tg) remained stable. These findings provide evidence-based guidance for material selection, aligner replacement cycles, and patient management protocols in clinical practice.

Topic 3: Nanodiamond Optical Sensor
This topic introduces the development of a nanodiamond optical sensor using micro 3D printing technology and its integration into aligners. Integrating this sensor directly into a clear aligner enables real-time monitoring of orthodontic force, contributing to optimized orthodontic appliance design and a breakthrough improvement in clinical treatment outcomes. In particular, AI-analysis-based personalized treatment planning improves patient compliance, prevents side effects, and ensures predictable final treatment outcomes.

While using Exocad DentalCAD, one of the dental CAD programs, many users are unfamiliar with the underlying principles or specific functions of the program, and as a result fail to make use of, or apply, its useful features. Exocad DentalCAD has many functions, and understanding the principles behind each one and putting them to practical use can save time and cost in our daily work.

This lecture will share a variety of quick tips for using Exocad DentalCAD, along with an introduction to the features upgraded in the 3.3 Chemnitz version.

1. Background and Need for the Technology
Conventional tooth shade measurement for prosthesis fabrication has relied on visual comparison or simple photo correction, which has the limitation that the original color data becomes contaminated depending on the lighting environment or the operator's subjective judgment.
To solve this problem, these systems adopted a "cross-polarized filter" photography technique that physically blocks surface reflection — the key cause of this optical error.
This prevents data loss in reflective areas and transmits only internally scattered light, extracting pure color data such as the tooth's inherent translucency and microstructure, ensuring reproducible measurements regardless of the environment.

2. Core Diagnostic Technology and the AI Mapping Process
While it is commonly understood that cross-polarized photography normally requires expensive cameras and dedicated equipment, this can be achieved with a smartphone and simple equipment alone, producing results comparable to expensive equipment — and AI performs a comprehensive, objective diagnosis using a single polarized photo.
The extracted pixel information is precisely decomposed into the Lab* color space (lightness, redness, yellowness) and analyzed quantitatively through three-dimensional color difference (ΔE) calculations. The analysis results are automatically generated as three types of visualization maps: a color map (color deviation on the tooth surface), a value map (brightness difference), and a translucency map (enamel and dentin translucency). In addition, two shade guides are simultaneously recognized for cross-validation of results, and the color distribution of the gingiva is automatically classified into four levels, providing a comprehensive analysis of the variables needed for prosthesis fabrication.

3. Human-AI Collaborative Recipe Generation
The defining feature of this AI-powered system is that it adopts an active collaboration model that respects human experience, rather than producing one-sided mechanical results.
When the AI's quantitative data analysis differs from the qualitative visual judgment of an on-site expert, the user can directly select and modify the diagnostic values.
As soon as user feedback is entered, the system updates its calculations and regenerates all visualization maps and detailed recipes in real time, producing an optimal result that fuses technology with the accumulated know-how of experts.

Over the past few years, dentistry has rapidly shifted from analog to digital.
CAD/CAM, intraoral scanners, and similar tools have become indispensable, and accordingly both the clinical and laboratory sides now need a strong understanding of digital technology.
And now we are facing another turning point.
The advancement of Artificial Intelligence (AI) is also affecting the field of dentistry.
Naturally, it is having a significant impact on the dental lab field as well, and this lecture will explain where and how it can currently be applied.
1) Applications in CAD (Exocad)
2) Applications in shade matching
3) The process and use of merging facial scans, intraoral scans, CBCT, and occlusal movement data

Beauty is not merely a result completed in a single moment — it becomes more valuable when it can be maintained over time. The esthetics we pursue also gain lasting value only when they go beyond reproducing isolated forms, achieving harmony among the natural tooth's shape and shade, a stable occlusal relationship within the mouth, and coordination with the gingiva. In clinical practice, we constantly consider these factors when fabricating prostheses, believing that small differences determine the long-term quality of esthetics and function. Through real clinical cases, this lecture shares the process and know-how considered in achieving lasting esthetic harmony.

Both clinics and dental labs nationwide are currently experiencing what could be called a laminate boom. This presentation introduces the overall laminate fabrication process.
There are several types of laminate treatment, but since it tends to be used more for cosmetic improvement than for treating caries, communication with the clinic starting from the initial diagnostic model is especially important, more so than for other treatment areas.
The digital utilization in the laminate fabrication process has also increased significantly, but because intraoral fitting in the clinic is more demanding than for conventional prostheses, skilled, detailed finishing that includes analog steps remains important.
Our lab handles cosmetic laminate cases that incorporate bleach shades, but we are increasingly receiving requests for laminate cases that blend more harmoniously with the surrounding teeth.
This presentation introduces the process for various clinical cases, including no-prep laminates, laminates for peg-shaped (small) teeth, and laminates performed alongside conventional prosthetics or implants.
Drawing on a variety of cases handled clinically, we will explain the material selection involved in laminate fabrication, the lab process, causes of failure, diagnostic model analysis, diagnostic wax-up, design precautions, form reproduction, and shade reproduction.

This lecture, aimed at dental technicians, systematically covers everything from tooth form theory to the actual zirconia contouring process for creating natural, functional prostheses.

Participants will learn to understand the anatomical form and occlusion of teeth, and to design optimal tooth forms through pre-sintering zirconia contouring. The lecture also delivers practical, hands-on know-how on post-sintering form changes, surface adjustment, texture expression, and finishing contouring, providing techniques that can be applied directly in the clinic and lab.

In prosthetic treatment for edentulous patients, esthetics begins with an understanding of tooth arrangement. This lecture examines how the principles of complete denture tooth arrangement carry over into full-arch implant prosthesis design, and introduces a restoration-driven approach that starts from esthetic arrangement. It presents concepts for achieving esthetic arrangement and establishing the occlusal plane without relying on a wax rim, sharing perspectives that can be applied directly in the lab. It is hoped this will be an opportunity to consider together how thinking that begins with tooth arrangement in edentulous patients can achieve esthetics in both complete dentures and full-arch implant prostheses.

Selection and Use of Appliances for Growth-Period Orthodontics

The growth period is a time of active change in the craniofacial structure, making it an important opportunity to maximize the effect of orthodontic treatment. This lecture examines the various types and characteristics of orthodontic appliances used for growing patients, and discusses in depth the fabrication principles and clinical application methods of each appliance from an orthodontic dental technician's perspective.
From appliances that apply mechanical orthodontic force to orthopedic appliances, the components of each appliance and precautions for fabrication are reviewed in detail, and criteria for selecting the appropriate appliance according to growth stage are presented. Through this, the lecture aims to improve laboratory precision in clinical practice and contribute to greater treatment efficiency.

What Makes a Good Appliance: One Dental Technician's Thoughts

The quality of an orthodontic appliance directly affects treatment outcomes, making the role of the orthodontic technician who fabricates it extremely important. Drawing on years of clinical experience, this lecture shares one technician's perspective and philosophy on what makes a good orthodontic appliance. Beyond mere fabrication skill, it emphasizes the importance of integrated thinking that considers an appliance's functionality, esthetics, and patient fit all at once, and examines the judgment criteria and key elements of quality control in the fabrication process through a variety of cases encountered in clinical practice. It also revisits the essential value of a good appliance that remains unchanged even amid the introduction of digital technology and a changing clinical environment. This lecture aims to help orthodontic technicians reflect on their everyday fabrication process and explore practical directions for better clinical outcomes together.

Minimally invasive laminate veneers offer the advantages of preserving natural tooth structure while achieving highly esthetic outcomes. However, predictable clinical success depends on accurate diagnosis and close communication between the clinician and the dental laboratory.

This lecture presents a systematic approach to improving the predictability of minimally invasive laminate veneer treatment based on real clinical cases. It begins by reviewing the key elements of esthetic analysis, including facial and dental evaluation, tooth morphology and proportion, occlusal assessment, and determination of the appropriate amount of tooth reduction. Practical strategies for effective communication between the dental clinic and laboratory throughout the treatment planning process will also be discussed.

The lecture will then introduce various clinical cases, including no-preparation (No-Prep) veneers, minimally invasive veneer cases, feldspathic ceramic laminate veneers, and multiple-unit veneer restorations. Through these cases, different treatment approaches, material selection, and techniques for reproducing natural tooth form and shade will be presented.

Finally, the lecture will highlight the role of the dental technician in fabricating esthetic restorations that harmonize with the natural dentition under minimally invasive conditions. Drawing on extensive clinical experience, it will provide practical insights and laboratory techniques that participants can immediately apply in daily practice.

As digital implant treatment becomes more widespread, the role of the dental technician in surgical guide fabrication is becoming increasingly important. This lecture reviews the essential factors to consider when designing a guide, centered on the surgical kit configuration for each implant system and the relationship between drill diameter, length, stoppers, and sleeves — knowledge required for accurate guide fabrication. In particular, it discusses problems that frequently arise during the actual fabrication process, such as sources of error in CBCT and intraoral scan data registration, sleeve height and position setting, drill interference, and causes of insertion depth and path error, along with methods for addressing them. It also presents design strategies for preventing these issues and checkpoints for technicians, with the goal of improving clinical accuracy and reproducibility, thereby strengthening collaboration between the clinic and the lab and contributing to more predictable outcomes.

In today's world, where analog dental technology is transforming into a digital one, this lecture explores everything about the fabrication process and tooth arrangement of Digital Dentures that maintain occlusion without displacement.

From interim to final dentures, this lecture takes an in-depth look at a variety of clinical cases and material characteristics of milled and printed dentures made using digital methods.
The rapid spread of intraoral scanners in recent years has been driving a fast evolution in the denture fabrication paradigm. Accordingly, this lecture will share in detail the process of transitioning from analog to digital, the clinical advantages unique to digital dentures, and practical guidelines that labs should prepare in order to successfully adopt them.

Esthetic restoration through complete dentures in edentulous patients goes beyond simple tooth replacement; this lecture aims to examine the harmony of the facial appearance, the restoration of a natural look, and the esthetic factors and clinical considerations that should be addressed when fabricating complete dentures.
For complete denture patients, esthetic factors are comprehensively evaluated, including facial analysis, vertical dimension setting, anterior tooth arrangement, tooth form and shade selection, and gingival contouring. Phonetic testing and functional evaluation are also carried out together to examine the relationship between esthetics and function. Proper vertical dimension setting and lip support restoration play an important role in improving facial appearance; harmony between the midline of the anterior teeth and the smile line has a decisive effect on natural esthetics; tooth form and shade selection that reflect the patient's age and facial characteristics affect esthetic satisfaction; and reproducing the form and shade of the gingiva restores overall naturalness. Esthetic satisfaction is also higher when stable phonetics and masticatory function are secured.
Esthetic restoration in complete denture patients can only be achieved when facial support, anterior arrangement, tooth selection, gingival reproduction, and functional factors are organically combined, and we will look at how a customized approach reflecting each patient's individual characteristics is a key factor for esthetic and functional success.

We have now entered an era in which prosthesis fabrication is genuinely based on digital dentistry. In particular, many methods and solutions have been introduced for fabricating prostheses directly or indirectly using 3D printers. While the conventional milling method for prosthesis fabrication is already very familiar, with extensive information available on its process, results, and materials, the use of the printing (layering) method to directly fabricate prostheses, and the use of model-less systems to print check and working models for prosthesis verification, along with printing intermediate outputs used in fabricating various types of dental prostheses, are also increasing rapidly. However, sufficient information about understanding dental 3D printers and the combinations and characteristics of materials has not yet been fully disclosed, so use in dental labs is sometimes not smooth. In particular, hybrid 3D printing resins, which are attracting a great deal of interest, still require a great deal more information.

Through this lecture, we will examine the physical properties of printing resins that dental labs must know, especially their characteristics based on materials science data, and explore how to make prosthesis fabrication work more efficient.

Topic: Esthetic Prosthetic Work That Retains Its Value Even in the Age of A.I.

Even in the age of A.I., the value that shines from a dental technician's hands will never disappear. This lecture addresses "color," the core of esthetic prosthetic work, and highlights points that are easy to miss when reproducing the color of a natural tooth. Rather than relying purely on intuition, it introduces a way to express the three elements of color — value, chroma, and hue — in the scientific language of L*a*b* values. However, numbers alone are not enough to achieve a perfect reproduction, because various real-world clinical variables — light source, surrounding environment, and the patient's individual characteristics — affect color perception. The lecture shares precautions for avoiding these pitfalls, along with small tips and know-how for achieving natural color. Going beyond simple technical explanation, this will be a time to consider together how the "sense" of reading and handling color can remain a technician's unique value even in the age of AI. Esthetic prosthetic work is not merely a matter of restoring teeth — it is an art that restores a patient's confidence. Through this lecture, participants will experience both the science and the art of color reproduction, and reaffirm the professionalism and pride of dental technicians that will not waver even in the future.
"Numbers (L*a*b*) don't lie, but interpreting those numbers is the technician's artistic insight."

In current dental clinical practice in Korea, zirconia has established itself as the most common and essential prosthetic restorative material, owing to its excellent physical properties and biocompatibility. Of the two major axes that determine the quality of a prosthesis — morphology and shade — the morphological aspect has already reached a fairly high, standardized level thanks to remarkable advances in digital dentistry and CAD/CAM technology.

However, morphological precision alone cannot guarantee perfect esthetics, and when it comes to "achieving a shade" that naturally harmonizes with the patient's natural teeth, the reality in clinical practice is that results still vary greatly depending on the operator's skill level and understanding of the material. No matter how precisely a prosthesis is designed, if it fails to convey lifelike optical properties, its value as a final result is inevitably diminished.

This lecture therefore takes an in-depth look at a systematic shade-reproduction methodology for overcoming the esthetic limitations of zirconia prostheses and achieving a higher level of prosthesis quality.
