미소교정; 아름다운 미소 만들기
New Concepts for Creating an Attractive Display of the Teeth and Beautiful Smiles in Orthodontic Patients


치아만 가지런하게 되었다고 교정이 된 것은 아니다. 많은 환자들은 매력적인 스마일을 얻기 위해 교정을 원하고 있으므로, 스마일시 치아의 노출에 대한 고려가 반드시 필요하다. 아름답고 매력적인 미소를 만들기 위한 최신교정지견을 전형적 증례와 함께 제시하고자 한다 (3 hrs)

During orthodontic treatment, it is easy to make several mistakes when it comes to the patient's display of the dentition in rest position, normal conversation, and full smile.This will undoubtedly reduce the benefits from an otherwise successful orthodontic treatment result. This lecture will discuss some new concepts and provide guidelines on how to evaluate tooth display and orthodontic smiles from the front, and with the patient sitting in the dental chair.
The lecture on the vertical dimension will emphasize the most attractive relationship between the upper incisal curve and the inner contour of the lower lip, and how to achieve that clinically. It will also discuss the optimal vertical display of maxillary and mandibular incisors in different age groups. The normal age changes in vertical incisor display in adult and elderly male and female patients will be analyzed. Such changes are caused by drooping of facial soft tissues due to gravitation. The treatment implications will be discussed with regard to vertical incisor exposure in different facial types. Particularly the unesthetic sequel associated with intrusion of maxillary incisors in patients with normal and low smile types will be illustrated so that "hiding the maxillary incisors behind the upper lip" will be avoided during orthodontic treatment.
For the transverse dimension, new information will be provided on the need for individual cuspid/bicuspid/molar torque variations in different facial types, so as to create fullness of smiles without lateral expansion. Diagnosis and handling of pretreatment asymmetries in crown torque between teeth on the right and left sides of the mouth will be discussed. The importance of treating to relatively straight crown torque of the most terminal maxillary bicuspid shown on smiling for achieving an attractive smile will be demonstrated. The most desirable crown torque of mandibular cuspids, bicuspids and molars from esthetic and functional perspectives will be analyzed. Optimal crown torque variations of the posterior teeth will be related to different sizes of the apical base in individual patients.

 

심미적 마무리 기술; 성인에서의 고려
Esthetics in Orthodontic Finishing


교정치료 후 최선의 심미를 얻기 위해서는 치아의 위치 뿐 아니라 치아형태, 나아가 치은형태에 대한 고려도 반드시 필요하다. 마무리 과정 중 치아삭제를 통한 recontouring 기법과 보철 및 치주술식을 동반한 심미적 마무리에 대한 임상적 가이드라인을 소개하고자 한다 (3 hrs)

Based on the research evidence from different experimental models to be presented, this section will provide many clinical tips on making intentional changes in tooth morphology and marginal gingivae. This is required in order to perfect orthodontic treatment results in adolescent and, particularly, in adult cases. The goal for each patient is a beautiful alignment of beautiful teeth, surrounded by intact gingival papillae.
Topics will include:

  • grinding with diamond instruments to change tooth form for esthetic, functional, and stability reasons.
  • mesiodistal enamel reduction (stripping) to reshape teeth to ideal morphology, and treat or prevent the development of interdental gingival recession ("black triangles").
  • routine and more difficult incisal edge contourings.
  • the use of porcelain laminate veneers and veneer crowns in adult orthodontic patients and in difficult/complicated adolescent cases involving autotransplantation of developing bicuspids to the maxillary anterior region.
  • different techniques for crown lengthening procedures associated with orthodontic treatment (gingivectomy, intrusion, extrusion, surgery including ostectomy).

Detailed how-to-do-it advice on the various procedures will be given to illustrate optimal performance and common mistakes for each, and many clinical examples will be provided for each item in this lecture.

 

새로운 패러다임; 노인교정
Orthodontic Treatment for Elderly Adults - Possibilities and Patient Reactions


인구의 노령화와 함께 사회경제적 여건이 향상되면서 교정치료를 원하는 연령층도 점점 높아지고 있다. 최근에 치료된 65세 이상 노인 30여명의 치료 경험을 통하여 "노인교정"의 가능성과 함께 성공을 위한 임상지침을 소개하고자 한다 (1 1/2 hr)

This lecture discusses the possibilities for orthodontic treatment in a large pool of elderly adults. All patients in the sample (n=36) were over 65 years of age, and the oldest was 84 years old, at the start of treatment.
Surprisingly positive reactions were experienced. Despite somewhat slow movements of the teeth in a few persons, treatment outcome generally was successful.
Discussions will include when to make compromise treatments, pathologic reactions in patients with psychologic problems, special problems in bonding and debonding adults with large fillings and many artificial teeth, and retention of the achieved results in elderly orthodontic patients.

 

하전치 일치 발치; 체계적 심층분석
Extraction of One Single Incisor in Orthodontics


성인에서 간단히 치료할 수 있는 교정술식으로 하전치 일치 발치가 있다. 이 경우 나타날 수 있는 문제점과 아울러 올바른 증례선택 방법을 제시하고자 한다. 특히 interdental gingiva 소실로 인한 심미적 문제와 함께 그 해결책을 논의하고자 한다 (1 1/2 hr)

This section will discuss the indications, contraindications, and clinical experiences for the extraction of one lower mandibular incisor in orthodontic treatment. One particular indication to be discussed is cases with a combined tendency for Class III malocclusion plus open bite. The advantages and disadvantages of such treatment will be evaluated, and clinical guidelines will be provided on the outcome of such extractions in different malocclusions treated at different ages. Special attention will be directed towards avoiding loss of the interdental gingival papillae in the mandibular anterior region.

 

심미치과의 미래; 치주, 보철, 교정, 임프란트의 협진!
Esthetic Dentistry for the Future - Cooperation between Specialists


교정학의 미래는 타 분야 전문의와의 협진체제 성공 여부에 달려있다. 보철교정 뿐 아니라 치주, 임프란트와의 협진을 최신지견과 함께 소개하고자 한다. 아울러 여러 형태의 implant와 microscrew의 장단점에 대하여 논의하는 한편, 치주가 좋지 않은 성인환자에서의 치료 가이드라인을 제시하고자 한다 (3 hrs)

This topic will cover and demonstrate in detail the clinical results achieved in interdisciplinary cooperation between contemporary orthodontics and excellent prosthodontics. It will be shown that the outcome is equally dependent on both specialists, and that the final result will be better than each of the specialists can achieve alone.
Also the cooperation between orthodontist and periodontist/implantologist will be covered. Recent advances in basic science related to periodontal biology, and clinical trials on prevention and treatment of periodontal disease, have changed many treatment concepts in periodontics. This information is important to clinical orthodontists who treat more and more complex adult cases. Interdisciplinary treatment regimes for adults with more or less reduced periodontal support will be covered, as will the advantages, disadvantages, and clinical problems for orthodontists of different types of implants and microscrews.
