HyFlex for You-Basic Sequence for Routine Endo Practice

In recent years, the role of NiTi rotary files in root canal treatment is of utmost importance. Although there have been many developments, HyFlex CM and EDM, which appeared in 2011 and 2016, can be said to have marked a milestone in the history of the development of heat treatment files. These two brought about fundamental changes that could be felt by beginners as well as experts.

Therefore, I would like to present basic skills and how to use these two in routine clinical practice for those who are entering root canal treatment.

• Title : [Lecture] Current Advances in Peri-Implantitis
• Date : Dec 1(Fri), at 16:30

(Lecture) Current advances of peri-implantitis

In the half-century since Branemark reported on dental implant in the 1950s, effectiveness and stable prognosis of implant have been thoroughly tested and proven, and a huge number of implants have been placed worldwide. As a result, practitioners and patients alike now recognize that dental implants are an excellent treatment option for restoring aesthetics and function when teeth are lost. However, there are still several problems that have been reported. At the 2017 World workshop, professors and masters in the field of periodontics and implantology presented a new classification of peri-implant diseases in addition to periodontal diseases. In this lecture, I will go over the new classification of peri-implant diseases in 2017 and summarize the evidence-based solutions and limitations about peri-implantitis reported to date. In addition, we will discuss the causes, diagnosis, and risk factors of peri-implantitis, and look into what the best possible treatment options are. Moreover, I will further discuss the prognosis and maintenance of peri-implantitis.

• Title : [Lecture] Guideline and Trend of Pulp Therapy in Primary Tooth
• Date : Dec 2(Sat), at 09:00
• Room : EXCO Room 325

The purpose of pulp therapy in the deciduous dentition is not only to eliminate pain, but also to preserve arch length, maintenance of mastication, pronunciation and aesthetic functions, prevention of bad habits, and emotional stability. For successful pulp treatment, an accurate diagnosis is necessary. In children, taking an accurate history of the presence and pattern of pain is an important factor in evaluating pulp status. In addition, clinical examinations such as mobility and percussion and radiological examinations must be conducted, and an understanding of the physiological characteristics and anatomical form of primary teeth, which are different from permanent teeth, is necessary.
Pulpectomy is a root canal procedure for pulp tissue that is irreversibly inflamed or necrotic due to caries or trauma. The root canals are debrided and shaped with hand or rotary files and then irrigated. After the canals are dried, a resorbable material is used to fill the canals. The tooth then is restored with a restoration that seals the tooth from microleakage. Pulpotomy is performed in a primary tooth when caries removal results in a pulp exposure in a tooth with a normal pulp or reversible pulpitis or after a traumatic pulp exposure and there is no radiographic sign of infection or pathologic resorption. The coronal pulp is amputated, pulpal hemorrhage is controlled, and the remaining vital radicular pulp tissue surface is treated with a long-term clinically-successful medicament. After the coronal pulp chamber is filled with a suitable base, the tooth is restored with a restoration that seals the tooth from microleakage.

• Title : [Lecture] Direct-Printed Aligner with Shape Memory Effect: Clinical Applications
• Date : Dec 1(Fri), at 16:00
• Room : EXCO Room 325

In recent years, clear aligner has been widespread in orthodontic treatment. The advantages of the clear aligner, such as esthetic appearance, patients’ comfort, and better oral hygiene, correspond to patients’ demands during the orthodontic treatment. However, the thermoformed process for conventional aligner fabrication includes several time-consuming steps. In addition, several weak points have been reported, such as unpredictable shrinkage of thickness, changes in mechanical properties, and geometric inaccuracy, directly associated with the predictability of tooth movement. Direct-printed clear aligners with shape memory effect may resolve the problems of thermoformed clear aligners. Furthermore, with the aid of direct 3D printing and shape memory effect, customization enables clinicians to apply them in diverse use and a consistent, light force can lead to physiologic tooth movement. In this presentation, the strength of the direct-printed clear aligners with shape memory effect compared with the thermoformed aligners will be discussed along with their clinical applications.

• Title : [Lecture] The Change of Bite Force after Botulinum Toxin Injection to 3 Masticatory Muscle
• Date : Dec 2(Sat), at 09:30
• Room : EXCO Room 325

In functions and biomechanics of the masticatory system, masseter and temporalis muscles work with medial pterygoid muscles. Bite forces ate an indicator of the functional state of the masticatory system and the level of maximum bite force results from the combined action of the jaw elevators. Botulinum toxin injection in masseter and temporal muscles is used in various reason in orofacial area. However, injection in medial pterygoid muscle is not studied. Although the volume of medial pterygoid muscle is about one third of masseter muscle, its action is related with bite force. We need to pay attention in the phenomenon that the medial pterygoid muscle can be very hyperactive in jaw closing dystonia as a result of the so-called “whack-a-mole phenomenon” after repeated botulinum toxin injections into the masseter and temporalis muscles. In this lecture, the authors compare the serial changes of maximum bite forces after botulinum toxin injections in masseter, temporal muscles and medial pterygoid muscles.

Digital dentistry has undergone rapid development in recent years, and its use also tends to be popular. It has a real-time visualization, reducing time and cost. In response to these developments, conventional impression method can be replaced by optical impression method. Also, several steps of prosthesis fabrication now can be replaced by the CAD-CAM system.This lecture introduces the materials needed to effectively use digital dentistry and the areas of digital dentistry that can successfully replace traditional methods.

• Title : [Lecture] Esthetic Implant Prostheses for Fully Edentulous Patients; Digital Blueprint and Analog Fine-Tune
• Date : Dec 2(Sat), at 13:00
• Room : EXCO Room 325

For the past 60 years, a dental implant has been used as a valid treatment option, and it has brought the quality of patients' life higher subsequent to the second human natural teeth. It’s become possible and predictable due to the huge development of characteristics of implant surfaces and their design. Nowadays, numerous data support the implant success and survival rate going up to higher than 90%. Besides, in contemporary dental society, much digital technology has merged into our daily dental practice. Oral scanners, instead of conventional impression techniques with silicones, can be good examples. Their usage is good and widely used in simple cases, such as a single crown and bridges.
However, what about digital technology with complicated cases or full-mouth edentulous cases? Is it still valid and useful to use digital technology? Specifically, in the full-mouth rehabilitation case, it has to be dealt with more delicately, precisely, and accurately since the practitioner has to create everything regarding the patient's oral environment, such as CR, VD, occlusal scheme, etc. It’s known that digital methodology still has lots of errors and mismatching compared to the conventional method despite the fact of researchers' and practitioners’ endeavors.
In this lecture, the conventional way of full-mouth rehabilitation will be reviewed. Collaterally, the digital method will be compared in every single step, followed by which method can or will be substituted by the digital method for convenience and accuracy, which in turn, enhances the functions and esthetics of full-mouth prosthesis.
