In a single implant restoration of maxillary anterior teeth, it is difficult to accomplish an aesthetic restoration of the implant prosthesis in the case of gingival recession and bone defect problems. To maintain aesthetic stability in the long term, it is important to place the implant in the ideal position as well as the recovery of the soft tissue and harmony with the prosthesis. Not only ideal implant position but also the harmony with surrounding soft tissues are important to fabricate aesthetic implant prosthesis for these cases. for these cases, a 47- years -old male with lowered level of osseous crest and gingival recession on maxillary anterior tooth was treated with guided bone regeneration and gingival recontouring.

The aesthetic restoration of dental implants in the anterior maxilla is a challenge for clinicians because it requires proper harmony in three following conditions; reconstruction of hard tissue, soft tissue, and aesthetic prosthesis. A newer technique, VIP-CT (Vacularized Interpositional Periosteal Connective Tissue) graft has been introduced as an alternative to these technique which allows the clinicians perform large volume soft tissue augmentation in esthetic sites with a single procedure. The advantages of the VIP-CT graft technique are that it allows the reconstruction of large soft tissue deficiency, with little constriction postoperatively. Furthermore, it facilitates improved hard tissue augmentation due to the additional blood supply and improved bone healing by mesenchymal cells. Moreover, this technique reduces patient discomfort and treatment time. This clinical report describes the procedure of bone augmentation during immediate implantation in facial dehiscence defect, especially Vascularized Interpositional Periosteal Connective Tissue(VIP-CT) graft for aesthetic anterior soft tissue.

치관부 파절이나 치아결손 혹은 치아형태의 이상이나 변색된 치아등으로 보철치료가 요구되는 경우 저작, 연하, 발음등의 회복과 심미적인 회복이 중요한 목적이 되며, 전치부에서는 심미성이, 구치부에서는 기능적인 회복이 더욱 강조된다. 보철치료후 치료목적을 달성하고 건강한 구강내의 상태를 유지하기 위해서는 보철물이 지대치 및 주위조직에 생물학적으로 조화되어 병적상태를 유발시키지 않아야 하며, 이를 위해서는 시술전에 올바른 진단과 적절한 치료계획을 세우고, 지대치 형성, 인상채득 및 임시관 장착, 금속관 및 가공의치 제작, 구강내의 시적(try-in), cementation등 모든 과정을 주위조직과 관련하여 주위 깊게 행하여야 한다.

Successful treatment outcome of esthetic dentistry often requires team approach including orthodontist, surgeon and restorative dentist. Clinician should consider various treatment options to restore missing teeth, especially in anterior region. In this article, interdisciplinary treatment of restoring congenitally missing lateral incisor and unrestorable molars will be presented.

There have been a great number of developments in clinical techniques and dental materials in dentistry to date. Looking at these developments, while it could be seen that functional elements such as mastication were prioritized rather than aesthetic aspect in the past, aesthetic needs of patients have steadily increased over time and accordingly the aesthetic has become considered a priority in the development of dentistry. Although the first to be considered in discussing the aesthetic in clinical dentistry will be the white aesthetic that is the tooth part of prosthesis, the pink aesthetic that refers to the harmony of such prosthesis with gingiva can be an important consideration not to be ignored aesthetically. However, the harmony with the gingiva often cannot be obtained only by the beautiful prosthesis, and in particular, the pontic and implant areas have poor conditions to achieve the gingival (pink) aesthetic due to the absorption of alveolar ridge compared to natural teeth. Among the most important elements of the gingival aesthetic are the gingival level and the interproximal papilla height. It is very difficult to make the gingival aesthetic in the case of insufficient alveolar ridge, and the recovery of ridge volume and contour is necessary in order to overcome this condition. To this end, the most widely used method is the "connective tissue graft". Many techniques of the connective tissue graft have already been introduced for the ridge augmentation, and each technique has different purposes, and advantages and disadvantages. Rather, due to the excessive amount of techniques, there is confusion about selecting the right technique at a certain time. However, the goal is clear. Ways to increase the success rates must be found, and at the same time, a more favorable way to the gingival aesthetic is to be chosen. Thus, in this study, considerations for the gingival aesthetic that makes harmony and the techniques to achieve it are discussed.

Maxillary and mandibular anterior dental arches often have the problems of occlusal relation and esthetics by malformations of teeth, congenital missing, et at. Though the clinician usually use the anterior ratio to overcome this problems, he has the limitation of a direct application this ratio to the prediction of anterior occlusal relationship by the change of anterior ratio as dental arch form, intercanine width, segment depth and arch perimeter. So this study examine maxillary and mandibular anterior dental arch forms by least square method using Korean normal occlusion models(man : 20 casts, woman : 20 casts). Maxillary and mandibular anterior dental arches of Korean normal occlusion models are curve fitted to polynomial function, beta function, hyperbolic cosine function in order. And this accuracy of curve fitting is constant regardless of man/woman and maxilla/mandible. The relationships between intercanine width, segment depth, and arch perimeter based on this owe fitted dental arch form are acquired. This relationships will give the prediction of anterior dental arch form and the information of more accurate anterior ratio according to intercanine width.

Supernumerary tooth is one of the abnormalities in tooth number. Supernumerary tooth result from excessive proliferation of dental lamina and incidence reports identify a range of $0.3\sim0.8%$ in primary dentition, $1.0\sim3.5%$ in permanent dentition with males being affected twice as frequently as females, maxilla nine times as frequently as mandible The incidence is more in anterior tooth region than in posterior region. The most common supernumerary tooth is the mesiodens, which located between maxillary central incisors. The occurrence is very rare in the incisor region of mandible and the reports on incidence is 2%. In this case, there were two supernumerary teeth in the mandibular region and we could acquire normal alignment of mandibular incisors by extraction and orthodontic treatment.

This research is studied the systemic production method of missing teeth and ridge lap type pontic for the maintenance and restoration of normal function of the surrounding tissue as the goal of prosthetic treatment. According to the dentists' opinions, with the illustrated design criteria that pontic has to be equipped, inflammation, periodontal disease, food residues, and self-cleaning effect are obtained a better result than the conventional production method. The pontic production method presented in this paper is considered good enough to be applied to a clinically.
