Treatment of skeletal Class III malocclusion with mini-implant anchorage is discussed in relation to vertical control of the maxillary posterior dentoalveolar region and horizontal control of mandibular anterior teeth. A midpalatal mini-implant provided anchorage for intruding the maxillary posterior teeth. Mandibular mini-Implant implants were used to bring about labioversion of mandibular anterior teeth. After mandibular setback surgery, improvement of the facial profile was obtained both horizontally and vertically, Total treatment time was 11 months. Stable occlusion was maintained after 18 months of retention, The effectiveness and efficacy of mini-implants for the treatment of skeletal Class III malocclusion are also discussed.

Collective changes caused by orthodontic tooth movement evaluated in a specific treatment modality could give suggestive information on the specific treatment strategy. The aim of this study was to investigate retrospectively the characteristics of the orthodontic tooth movement during surgical-orthodontic treatment in order to provide an effective presurgical orthodontic treatment planning for the maxillary premolar extraction modality In the skeletal Class III malocclusion patient. Pre- and post-treatment dental casts of skeletal Class III malocclusion patients with nonextraction (N=:24) and the maxillary premolar extraction (N=31) were collected. The angulation and inclination measuring gauge(Invisitech Co. Seoul, Korea) was used to evaluate the orthodontic tooth movement. The changes in the maxillary and mandibular dental arch widths were also measured from the canines to the second molars. As a result, more palatal inclination change in the maxillary dentition was found with the premolar extraction modality than with the nonextraction modality. Linear regression analysis showed that the inter-arch width coordination was mainly due to the inclination changes of maxillary posterior teeth We conclude that the indications and proper treatment planning for surgical-orthodontic treatment in skeletal Class III malocclusion with maxillary premolar extraction could depend partly on the magnitude of the transverse inter-arch coordination especially in the maxillary dentition.

족부의 교정을 위해서는 비정상적인 상태 및 원인 그 치료법에 대해서 충분히 이해해야 할 것으로 생각되며, 비 척행족에 대해서는 먼저 정확한 원인 인자의 파악과 수술전 평가, 수술의 선택, 수술의 범위등을 정해야 한다. 이렇게 함으로써 변형에 대한 충분한 교정이 가능하며, 수술후 예후가 좋은 척행족으로 될 것이다. 그리고 위에서 밝힌 치료의 원칙은 변하지 않겠지만, 관절 고정술을 대체하여 다른 남은 관절에 영향을 주지 않으면서 더 많은 유연성을 가질 수 있는 기능있는 족부를 만들 수 있는 새로운 수술방법이(관절 치환술등) 더 개발되어 져야할 것으로 생각된다.

Proper positioning of maxillary incisors is key to success of surgery combined treatment. Establishing surgery plan would be a difficult job if maxillary incisors are lost. Patient who lost all of her maxillary incisors due to accident came for orthodontic treatment. Through careful modification of maxillary archform, pre-surgical orthodontic treatment was conducted with four prosthetic space consolidation. Position of incisors was decided by help of 3D prosthetic set-up, and 1-jaw surgery was planned. After relative short treatment period of 28 months, final prosthesis was done. When alveolar bone loss happens, harmonious prosthesis of upper incisors is difficult. Utilizing mandibular set-back surgery and incisor positioning using 3D set-up could make a better environment for treatment outcome. Strategic pre-surgical orthodontic treatment can allow shorter time and less number of prosthetics.

Objective: To evaluate the discrepancies between initial STO and final STO in Class III malocclusions and to find which factors are related to the discrepancies. Methods: Twenty patients were selected for the extraction group and 20 patients for the non-extraction group. They were diagnosed as skeletal Class III and received presurgical orthodontic treatment and mandibular set-back surgery at Pusan National University Hospital. The lateral cephalograms were analyzed for initial STO (T1s) at pretreatment and final STO (T2s) after presurgical orthodontic treatment, and specified the landmarks 3s coordinates of the X and V axes. Results: Differences in hard tissue points (T1s-T2s) in the X coordinates of upper central incisor edge, upper first molar mesial end surface, lower central incisor apex, lower first molar mesial end surface and mesio-buccal cusp and Y coordinates of upper central incisor edge, upper central incisor apex, upper first molar mesio-buccal cusp were statistically significant in the extraction group. Differences in hard tissue points (T1s-T2s) in the X coordinates of upper central incisor edge, lower central incisor apex, lower first molar mesial end surface and Y coordinates of lower central incisor apex were statistically significant in the non-extraction group. In the extraction group, the upper arch length discrepancy (UALD) had a statistically significant effect on maxillary incisor and first molar estimation. Lower arch length discrepancy and IMPA had statistically significant effects on mandibular incisor estimation in both groups. Conclusions: Discrepancies between initial STO and final STO and factors contributing to the accuracy of initial STO must be considered in treatment planning of Class III surgical patients to increase the accuracy of prediction.

Clinical therapy that combines full-mouth rehabilitation with immediate implantation and orthognathic surgery poses a challenge to prosthodontists. This clinical report describes a multidisciplinary approach to the diagnosis and treatment of a patient presenting with skeletal discrepancy and rampant caries. The results thus achieved indicate that full-mouth rehabilitation by fixed immediate and early loading implantation accompanied by orthognathic surgery can be a predictable and effective treatment procedure.

배경: 누두흉은 앞가슴 기형 중 가장 흔하며 Meyer 등이 1911년 수술적 교정을 시행한 이래로 많은 술식들이 개발되어 왔다. 이들의 대부분은 전흉벽에 상처를 내고 늑연골을 자르는 과정이 필요하였다. 그러나 Nuss 등에 의해서 상기 과정없이 작은 옆가슴의 상처와 stainless steel bar로 흉골의 기형을 교정하는 국소침습적 방법이 개발되었다. 대상 및 방법: 1999년 11월부터 2000년 7월까지 누두흉의 교정을 원하는 환자 14예를 대상으로 하였다. 수술은 15세미만에서는 pectus bar를 1개를 사용하였고 그 이상에서는 2개를 사용하여 교정하였다. 결과: 남자는 11예, 여자는 3예 였으며 나이는 2세에서 52세 사이였다. 누두흉 지표는 5.3$\pm$1.84였고 비대칭지표는 1.06$\pm$0.03이였다. 수술 후 2일째 모두 일반병실로 올라갔다. 평균 재원기간은 4.2일이였다. 술후 합병증으로 성인에서 기흉 1예, 혈흉 1예, 그리고 나중에 발생한 흉막액 1예가 있었다. 결론: 누두흉에서 Nuss 술식으로 좋은 결과를 얻었다. 성인에서도 bar 2개를 이용하여 교정이 가능하였으나 소아에 비하여 합병증이 많이 발생하였는데 이는 성인에서 근육이 발달되어 있고, 뼈의 골화가 다 진행되었기 때문이다.

Severe skeletal anteroposterior and vertical discrepancy is difficult to obtain satisfactory result by only orthodontic treatment, and much anteroposterior movement and treatment stability require orthodontic treatment with orthognathic surgery. The treatment goal of mandibular prognathic patients is to promote the function of stomatognathic system including mastication and phonetics, to improve the esthetics of facial profile and to maintain stability. Positional changes of hyoid bone, pharynx and tongue were seen with mandibular movement after orthognathic surgery. This study was performed to observe the changes of perimandibular tissues of orthodontic patients with skeletal mandibular prognathism who treated with orthodontic treatment, and the changes of hyoid bone, pharyx and tongue by relapse or recurrance after before and after orthognathic surgery and retention. The 22 patients who had mandibular prognathism were selected. They treated with orthodontic treatment with sagittal split ramus osteotomy as orthognathic surgery. And lateral cephalometric radiographs were taken 3 times : pre-surgery (T1), immediate post-surgery (T2) and 2 years alter retention (T3). The results were as follows : 1. The hyoid bone returned back after clockwise rotation to maxilla and occlusal plane during retention (P<0.01). 2. The hyoid bone moved posterior-inferiorly by mandibular surgery and returned back anterior-superior after retention. (P<0.01) 3. The changes of pharyngeal depth showed a little decrease at upper area in post- surgery, but it was not a significant difference generally through before, after and retention. 4. In relating to tongue base, the angle of tongue base was decreased and the dorsal area of tongue base moved to inferior-posterior direction and to superior direction again after retention (P<0.01). 5. Related to the thickness of upper and lower lip, the thickness of upper lip decreased after surgery, and the soft tissues below lower lip increased after surgery and decreased after retention.

The purpose of this study was to investigate the factors affecting the postsurgical mandibular stability for both one- and two jaw surgery. 18 for one-jaw surgerys and 24 for two-jaw surgerys among skeletal class III malocclusion patients who experienced orthodontic treatment and orthognathic surgery at Pusan National University Hospital were selected. Lateral cephalograms taken at the first visit, after presurgical orthodontic treatment, immediately after surgery and follow-up over 6 months, were traced. Based ANOVA, multiple linear regression analysis was completed for one-jaw surgery with postsurgical stability as the criterion and the magnitude of mandibular setback, the change of mandibular incisor height during surgery, the changes of mandibular plane angle and mandibular incisor angle during presurgical orthodontic treatment as affecting factors. Same analysis was completed for two-jaw surgery with postsurgical stability as the criterion and the magnitude of mandibular setback as affecting factor. The results were as follows : 1. In the one-jaw surgery cases, the magnitude of mandibular setback, the change of mandibular incisor height during surgery, the changes of mandibular plane angle and mandibular incisor angle during presurgical orthodontic treatment explained the variability in postsurgical stability with a significant $R^2$ value of 0.84. 2. In the two-jaw surgery cases, the magnitude of mandibular setback explained the variability in postsurgical stability with a significant $R^2$ value of 0,28.
