Today, CAD/CAM zirconia has become not just an option but a central material in dental prosthetics. Despite its much higher strength compared to traditional ceramic materials, frequent early fractures occur in clinical practice for reasons that are not fully understood.

In this presentation, we elucidate the causes of fractures due to milling-induced microdamage of the zirconia blocks and various inherent block material defects, as revealed in recent research. We investigate their impact on material strength and Weibull reliability.

The results of this study underscore the need for technological advancements to reduce damage during block processing and various internal material defects.

The field of dental technology has witnessed diverse changes in materials and fabrication methods amidst rapid growth and evolution. There is a constant need for evolving fabrication processes that align with advancing materials and substrates. This era requires relentless efforts to adapt to such changes and strive for technological advancements.

This presentation introduces aesthetic prosthesis fabrication processes that can enhance both efficiency and quality in dental laboratories. It outlines various utilization methods tailored to different clinical cases encountered during aesthetic prosthesis fabrication.

After introducing the appropriate use of ceramic stains and aesthetic expression methods, we will showcase clinical cases and demonstrate the process of case analysis and ceramic staining layering.

With the introduction of CAD/CAM systems, one highlighted advantage was the ability to mass-produce with fewer personnel. However, in the realm of tooth design using dental CAD, the reality is that it often takes a long time to reproduce natural-looking teeth, resulting in many instances where the advantages of CAD/CAM are not fully utilized.

Over the past two decades, digital technology has rapidly advanced in dentistry, enabling most fixed prostheses to be fabricated using digital techniques. However, digital research and clinical treatment in the field of removable partial dentures (RPDs) have lagged behind fixed prostheses due to their complex structures and diverse compositions.

In the past decade, our research team has conducted extensive research in the CAD/CAM field of RPDs. Our main research areas include digital design and fabrication of metal frameworks for RPDs, digital design and fabrication of RPDs, and research and development of preparation guides for RPDs.

Now, CAD and CAM have become essential elements in the production of dental prosthetics, and most prosthetic devices are manufactured using CAD and CAM.

Currently, devices using CAD CAM are being actively manufactured in orthodontics.

Computers are used for digital patient analysis, diagnosis, clear aligners, indirect bonding trays, and occlusal splints, but unlike dental prosthetics, many orthodontic devices are still manufactured manually by dental technicians.

This lecture will examine not only the production of dental orthodontic devices, but also the production of apicoectomy guides using CBCT, oral scan, and CAD CAM for dental treatment through the expansion of digital laboratory work.

Recently, the dental field has been undergoing significant changes towards digital-based dental prosthetics and treatments. As a result, it's true that dental laboratories and dental practices are becoming more convenient.

Some believe that analog methods should be the foundation for superior quality in digital prosthodontics. Particularly, in the anterior region, some instructors believe that there is a slight lack of aesthetics. In this lecture, essential elements for harmonious aesthetic treatment, prosthetic fabrication processes, and methods will be extensively discussed through clinical experiences and research, with detailed explanations using case studies.

Digital technology is being utilized in various ways in the field of dental treatment. From initial consultations to final prosthesis delivery, the digitization of both clinical and laboratory processes has made "digital dentistry" more accessible, with no longer a steep learning curve. However, the digitalization of accurate shade matching has been relatively slow compared to other advancements in dental digital technology, despite years of research and various attempts. This is because the process of quantifying and applying objective values to color has been challenging.

The shades of teeth that we need to mimic and reproduce are translucent, and the analysis of shades varies depending on the refraction of light and viewing angle. Obtaining accurate shade photos in the clinical setting is difficult, and creating a conducive environment for taking perfect shade photos in a busy clinical environment is also challenging.

The advantage of digitalization lies in providing accurate information. Unclear shade photos result in requests for modifications or remakes, leading to patient discomfort. Therefore, through "digital shade matching," if we can obtain accurate shade information from the clinical setting and express objective shades in prostheses, the area of shade matching can also become a part of digital dentistry.

In this lecture, I will explain the background knowledge required to obtain accurate shade photos for "digital shade matching" and introduce OptiShade equipment for obtaining objective shade information, as well as conducting a stain demo thereafter.

We invest a lot of time studying occlusion. However, occlusion has evolved in a way that makes it difficult for us to question it based on the theories we know and the surrounding environment.

We have been developing occlusion from the past to the present through trial and error in eating habits, that is, masticatory exercises.

However, we have overlooked occlusion in the unconscious state of sleep, considering occlusion in the conscious state and occlusion in the unconscious state as identical.

I wonder why this is happening?" "Something feels odd." Armed with these questions, we aim to explore occlusion, bruxism, temporomandibular joint issues, and oral devices for sleep apnea.

Defects can occur not only on teeth in the mouth, but also on a variety of areas, including the surface of our skin. There are many factors such as injury, cancer, congenital disease, etc., but there are many people who have a part of their body missing and become pessimistic, thinking, “I am different from others” or “Why am I the only one?”

The sunken skin after cancer extraction, the perforation that must always be covered with a mask or gauze, and the sense of loss of something missing must be unbearable pain. Changes in appearance cause more damage to patients with defects than we think. We call it “Appialan Care,” which deals with “patients who are concerned about changes in their appearance” and provides care for their appearance, including psychological support.

There are a variety of cases and methods for Appiaran care, but I use a method called epithesis to help people who are struggling with deficits live their daily lives in a more positive way. In this academic conference, we will look back on the past 10 years and introduce a mixture of case studies on how Apirance Care affects the mind.

Transition from BPS to Ivotion Denture System: 2 Solutions for High-Quality Full Dental Prosthetics

CAD/CAM-assisted fabrication of fixed prostheses is already established and widespread in many dental practices and dental technology laboratories today. In recent years, CAD/CAM-assisted removable prosthetics have also become increasingly important. This presentation will demonstrate the transition from a successful “analog” BPS workflow to the Ivotion Denture System. We will describe its meaningful use in the creation of high-quality removable prostheses and its current usefulness in daily work in clinics and technical rooms.

1. Introduction to BPS and conversion to Ivotion Denture System
2. Overview of recommended clinical and technical steps
3. Possible representations and alternative workflows
Overview of Equipment Required

Digital Dentistry, Custom Implants, CAD/CAM. 3D printing, transparent aligners... These are words that are familiar as key keywords in the dental engineering industry these days. In just 10 years since the introduction of an unfamiliar prosthetic material called zirconia, the dental industry has experienced many changes, and is expected to face various problems again.

The “Lost-wax technique,” ​​which has been the core of the dental prosthesis manufacturing process for the past 100 years, is now gradually disappearing. Every year, new materials and equipment are introduced, manufacturing processes are developed, and applied to our dental engineering field. However, research on these, dental engineering materials/parts/equipment, development of prosthesis manufacturing processes suitable for clinical use, verification, and various clinical applications are required. So much is lacking.

As dental technicians, who have been the foundation and core of the dental engineering industry for over half a century, we would like to think about what we need to prepare to become a player in the rapidly changing dental engineering industry.

When thinking about arrangement methods for aesthetic dentures Think about the gap between the arrangement based on generally known academic standards and the arrangement desired by patients. This is a presentation on what preparations dental technicians need to make in order to create a successful arrangement that will satisfy all patients, clinics, and labs.

As we enter the digital age, we may have had high expectations.
However, we are experiencing too many difficulties regarding the proper use and management of digital devices.

For this reason, “full digital labs” seem to be recognized as something special.
In this lecture, the presenter would like to talk about a solution that can be pivoted to a fully digital professional laboratory and a method of producing an All-on-X prosthesis (full arch prosthesis) that is easy, fast, and requires short chair time.

Anyone can create a fully digital professional laboratory.

 

When it comes to prosthetics, I believe that restoration of the patient's function comes first, followed by restoration of the patient's aesthetics. Therefore, when manufacturing ceramic-based prosthetics, we are always limited by aesthetic space due to functional reasons and patient requirements regarding sufficient prosthetic thickness. For these reasons and due to the clinical environment, dental technicians face many difficulties in producing aesthetic prosthetics.

In this lecture, I would like to tell the story of how I communicated with the clinic in producing aesthetic prosthetics based on a case I produced within this reality. I would also like to talk about the concept of “Opacity” that makes this action possible.

Prosthesis manufacturing based on digital dentistry is developing rapidly. In particular, the production of prosthetics using 3D printing technology is receiving a lot of attention. Previously, it was common to manufacture prosthetics through milling technology, but now methods of directly or indirectly manufacturing prosthetics through printing methods are being widely introduced.

There are various methods for making prosthetics. Unlike milling, printing uses a layering method to create prosthetics. Additionally, there is an increasing number of cases where various types of dental prosthesis are printed using model-less systems.

However, dental labs sometimes have difficulty using the technology because they do not yet have a sufficient understanding of the combination of printing technology and materials. Through this lecture, we will understand the basics of printers and materials in dental laboratories, learn how to use them in actual clinical practice, and look at efficient prosthetic manufacturing methods.

There are two main methods for making digital dentures: 3D printing and milling. Additionally, it requires integration of traditional denture fabrication techniques and expertise. In this article, we will comprehensively compare the manufacturing methods of traditional dentures and digital dentures. We will explain how existing methods are applied in designing and manufacturing digital dentures, and what technologies are needed for the new approach.

In particular, we will focus on the manufacturing method using Ivoclar's BPS (Biofunctional Prosthetics System) in the manufacturing of existing dentures. We will also provide an overview of how the BPS SYSTEM is applied using computer-aided design (CAD) for denture design, computer-assisted milling (CAM) and 3D printing workflows, and demonstrate clinical examples where these methods are utilized.

The first photography, named by Nyeps in 1826, involved dissolving bitumen in lavender oil and covering it with a layer of pewter, and taking long exposures of about eight hours. Then, in 1831, the daguerreotype method was invented by Daguerre, and the first paper printing method was invented by Fox Talbot, who was conducting the same research as Daguerre at the same time. Afterwards, Ipolit Bayard's direct lithography method and the gelatin dry plate method, in which a silver bromide emulsion was applied to a glass plate and dried in 1871, were introduced by Richard Ricci Medux. In 1888, cellulose-based roll film was commercialized by Eastman Kodak, which appeared with the advertisement “Just push the button,” and achieved remarkable development. Film cameras, which at one time could be considered the be-all and end-all of photography, quickly disappeared into the background with the advent of digital cameras and cameras mounted on mobile devices.

However, just as the public who was passionate about CD sound quality misses the analog melody of LP, the number of young people looking for film cameras is increasing these days.

Although many places where film development and printing were done with D&P points have disappeared, At local photo studios, you can even scan developed and printed films, and Digilog, which combines digital and analog, has developed into a form that satisfies everyone. I have been taking photos as a hobby for a long time.

Above all, photography has the function of recording the scene, and a single photograph recorded as a scene of a historical event can be said to have many meanings. Among them, developing film taken with a film camera, drying the developed film, and printing it using an enlarger can be said to be the highlight of the art of photography. In the digital age, corrections can be made easily using Photoshop or other photo editing programs, but slight modifications are also possible with film cameras during the development and printing process. The author set up a small darkroom at home and worked on film development and printing processes using an enlarger. In this lecture, I would like to introduce the photographic machines and tools used in the development and printing process and the results of work using them.

In addition, in this lecture, we will introduce easily accessible camera functions and various types of classic cameras, as well as talk about the types and functions of lenses and DSRL.

As we enter the era of the 4th Industrial Revolution, a new paradigm of convergence technology is being introduced as advanced technologies and various industries come together in a wide range of fields such as virtual reality, 3D printing, robots, and artificial intelligence. In particular, deep learning, one of the artificial intelligence analysis technologies, began to show results exceeding the performance of existing machine learning models by classifying objects in images using deep neural network models.

The value of utilizing medical big data in the field of artificial intelligence is evaluated very positively, and various studies are being attempted to improve national competitiveness by utilizing big data in healthcare, such as reducing medical costs and improving the quality of medical services. However, legal issues are being raised in terms of liability for information errors, liability for diagnosis and treatment errors, and the collection and use of personal medical information, and there are limitations such as the imperfect quality of medical prosthetics made with artificial intelligence.

The potential of artificial intelligence is very great, but it must be supported by analysis and response. In addition to strict data accessibility to protect personal information, different types of standardization are needed by country or organization, and above all, it is important to acquire specialized skills and knowledge to effectively utilize artificial intelligence. To this end, education and continuous capacity building for dental technicians and other professional personnel are very urgent. Therefore, in this presentation, we will discuss the current level of artificial intelligence technology and the basic knowledge required to respond to artificial intelligence as a dental technician.

Complex implant cases that require restoration of occlusion for full-mouth defects are an important task for dentists and dental technicians. Gradually, aesthetic and stable restoration requires prosthetics that include gingival areas with a lot of alveolar bone loss, as well as sturdy materials, esthetics, and cleanability.

This time, I would like to present the need for a prerequisite for total prosthetics that provides aesthetically satisfactory results while perfectly implementing the important diagnostic process and function that total prosthetics performs not only a functional role but also an aesthetic role.

Every work we do is accompanied by repeated failures and rework. This time, when I do fixed work (PFZ, monolithic, CAD….), what I consider important

and what I keep in mind to reduce the failure rate. I would like to share them with you along with the production process.

As a dental technician, I apply the N.A.T Concept to digital CAD design for the teeth I work with every day. Learn about the correct approach to manufacturing teeth using a combination of analog and digital methods, and learn tips and know-how for clinically utilizing CBCT DATA. We will announce it.

Since 2019, various programs have been provided to produce prosthetics using digital CAD. In studying and applying it to clinical practice, we will edit and use oral scan data and byte alignment in the future.

At this point, it is evidence that various know-how will become your own techniques and weapons, starting from 2023. With an introduction to B4D, a program that I have been studying and will continue to study in the future

Features of the program and design photos and video materials that are applied and utilized in clinical practice Through this lecture, we plan to give a lecture on digital engineering that we need to prepare for in the future.

In this lecture, we will create numerous complete dentures using odic dentures over the past 15 years. Understand the principles of Odic’s injection system and the advantages of other auxiliary materials for mandibular suction dentures. Understanding the principles of mandibular suction dentures and various edentulous conditions From my experience in lectures on surface tension, Let's solve it

In addition, it will be an opportunity to understand the various uses and repair methods of flexible dentures.

Oral trauma or disorders that can occur during sports can lead to fractures and dislocations of teeth and jaw fractures, which can lead to permanent disabilities. In particular, contact sports such as boxing and taekwondo can cause concussion or serious brain damage due to impact on the brain. In addition, with the development of living environments, the frequency of oral and maxillofacial trauma is increasing as leisure sports through club activities such as fighting sports, soccer, golf, in-line sports, and bicycles become active.

The sports mouth guard absorbs shock when the upper and lower teeth come into contact during a game, prevents severe shock to the temporomandibular joint, and prevents loss of consciousness or concussion when tooth shock is transmitted to the brain. It also prevents bleeding under the meninges, etc. It is an oral elastic protection device that can prevent.

In this lecture, we prepared the roles and types of sports mouth guards, international standard manufacturing methods suitable for sports events (custom made type using pressure molding method), clinical application according to sports events, and the role of dental technicians. Interested members I hope this will be a time for information sharing.
