현재 치과치료의 다양한 분야에서 디지털 기술이 활용되고 있다. 특히 전치부 심미수복에 있어 기존의 전통적인 수복방식은 안모 정보를 담을 수 없고 환자가 치료 결과를 예상하기 어려운 반면 디지털 디자인을 통한 심미수복의 경우 보철물 디자인의 시각화 및 환자 피드백 반영의 용이성, 치료 결과에 대한 예지성을 얻기 쉽다. 본 증례는 전치부 외상 환자에게서 디지털 방식을 이용하여 예상되는 치료 결과를 환자가 치료 전 확인하고 피드백을 반영하여 진행하였다. 2D 디지털 스마일 디자인 방식은 환자의 안모 및 미소정보로 2차원 평면상에서 디자인이 이루어져 적용에 다소 제한되는 점이 있었으나 본 증례에서는 3차원 가상환자를 만들어 진행하였기에 디자인된 보철물에 대하여 다양한 각도에서 확인 및 수정이 가능하였다. 본 증례를 통하여 디지털 방식을 이용한 심미 수복시 환자 및 기공사와의 원활한 소통, 치료결과에 대한 높은 만족도를 얻어낼 수 있었다.

In recent years, clinicians' and dentists' esthetic demands in dentistry have increased rapidly. The ultimate goal in modern restorative dentistry is to achieve "white" and "pink" esthetics in the esthetically important zones. Therefore, modern esthetic dentistry involves not only the restoration of lost teeth and their associated hard tissues, but increasingly the management and reconstruction of the encasing gingiva with adequate surgical techniques. Interdental space are filled by interdental papilla in the healthy gingiva, preventing plaque deposition and protecting periodontal tissue from infection. This also inhibits impaction of food remnants and whistling through the teeth during speech. These functional aspects are obviously important, but esthetic aspects are important as well. Complete and predictable restoration of lost interdental papillae remains one of the biggest challenges in periodontal reconstructive surgery. One of the most challenging and least predictable problems is the reconstruction of the lost interdental papilla. The interdental papilla, as a structure with minor blood supply, was left more or less untouched by clinicians. Most of the reconstructive techniques to rebuild lost interdental papillae focus on the maxillary anterior region, where esthetic defects appear interproximally as "black triangle". Causes for interdental tissue loss are, for example, commom periodontal diseases, tooth extraction, excessive surgical periodontal treatment, and localized progressive gingiva and periodontal diseases. If an interdental papilla is absent because of a diastema, orthodontic closure is the treatment of choice. "Creeping" papilla formation has been described by closing the interdental space and creating a contact area. In certain cases this formation can also be achieved with appropriate restorative techniques and alteration of the mesial contours of the adjacent teeth. The presence of an interdental papilla depends on the distance between the crest of bone and the interproximal contact point, allowing it to fill interdental spaces with soft tissue by altering the mesial contours of the adjacent teeth and positioning the contact point more apically. The interdental tissue can also be conditioned with the use of provisional crowns prior to the definitive restoration. If all other procedures are contraindicated or fail, prosthetic solutions have to be considered as the last possibility to rebuild lost interdental papillae. Interdental spaces can be filled using pink-colored resin or porcelain, and the use of a removable gingival mask might be the last opportunity to hide severe tissue defects.

With the explosive increase of esthetic demands by patients, many dental materials for the esthetic restoration have been introduced. Recently, zirconia based restorations are using for the cases of single crown, bridges, implant prostheses etc. Zirconia have superior mechanical properties and biocompatibility. Owing to the properties of high strength, zirconia has to be manufactured by CAD/CAM system. Dental CAD/CAM system is a futuristic treatment and technical system which makes it possible to produce the precision and uniform prosthesis and also standardize the treatments. This article introduces the characteristics of zirconia, fabrication procedure using CAD/CAM system and procedure for the cementation of zirconia based restoration.

The esthetic demands are growing in treatment of primary maxillary incisors as well as permanent ones. There is something dissatisfying about in the keen eyes of the pediatric dentists on their esthetic results of efforts because current tooth color system is created for the purpose of the application to the permanent incisors. In this study using the scientific color measurement device, I would like to introduce a color scheme for the primary maxillary incisors and suggest clinical tips for the better results of resin composite restorations.

Esthetic is one of the prime goal of the orthodontic treatment. It is represented by the word of harmony or balance. There is no absolute esthetic norm but it is important to study about it in orthodontic and orthognatic surgical treatment planning. The purpose of this study is to obtain the norm of Korean female adolescents who were candidates of 1986, 1987 Miss Korea Beauty Contest. The 77 individual samples were selected and studied by cephalometric analysis. Obtained results were as follows: 1 Korean esthetic norm was obtained. 2. Simple correlation coefficient was obtained between each measurements. 3. Holdaway ratio of Korean beauty was 3.3 : 1. 4. To compare with caucasian, profile of Korean beauty had less prominant nose, more prominant lip and deeper sulcus depth.

전치부 심미 보철에서의 성공은 안모에서의 심미와 구강 내 주의 치아와 치주 조직간의 조화라 할 수 있다. 정상적인 교합평면을 가진 안면대칭의 환자에서는 여러 심미 책에 나오듯 기준을 잘 정하고 그 기준에 맞게 제작하면 별 탈없이 조화롭고 심미적인 보철을 제작할 수 있다. 하지만 안면 비대칭 환자의 경우 안면 대칭의 환자의 기준에 억지로 맞추어 제작하게 되면 심미적이지도 않을뿐더러 기능적이지도 않은 결과로 끝나기 쉽다. 또한 치은 퇴축이 심한 환자의 경우 달라진 치아주위 환경에 맞게 보철의 형태를 부여해야만 치주조직에 조화롭고 심미적이며 자정작용이 뛰어난 보철제작이 가능하다.

Generalized aggressive periodontitis cause intrabony pocket, loss of teeth, and severe alveolar bone defect. As a result, pathologic tooth migration occurs and esthetic problem happens according to this, especially on the anterior teeth of maxilla. The purpose of this study was to assess the multidisciplinary treatment including periodontics, orthodontics and prosthetics of a patient caused by generalized aggressive periodontitis. This study presents a case using full mouth periodontal treatment, immediate orthodontic treatment for 5 months, implantation with guided bone regeneration and free gingival graft, and prosthetic treatment. Treatments took totally 14 months. Periodontal indicators such as probing pocket depth, bleeding on probing, tooth mobility improved. Also, the patient was satisfied with the esthetic and functional improvement.

Purpose: The aim of this study is to assess the influence exerted by the observer's dental specialization and compare patients' opinion with observers' opinion of the esthetics of maxillary single-tooth implants in the esthetic zone. Methods: Forty-one adult patients, who were treated with a single implant in the esthetic zone, were enrolled in this study. Eight observers (2 periodontists, 2 prosthodontists, 2 orthodontists and 2 senior dental students) applied the pink esthetic score (PES)/white esthetic score (WES) to 41 implant-supported single restorations twice with an interval of 4 weeks. We used a visual analog scale (VAS) to assess the patient's satisfaction with the treatment outcome from an esthetic point of view. Results: In the PES/WES, very good and moderate intraobserver agreements were noted between the first and second rating. The mean total PES/WES was $11.19{\pm}3.59$. The mean PES was $5.17{\pm}2.29$ and mean WES was $6.02{\pm}1.96$. In the total PES/WES, the difference between the groups was not significant. However, in the WES, the difference between the groups was significant and prosthodontists were found to have assigned poorer ratings than the other groups. Periodontists gave higher ratings than prosthodontists and senior dental students. Orthodontists were clearly more critical than the other observers. The statistical analysis revealed statistically significant correlation between patients' esthetic perception and dentists' perception of the anterior tooth. However, the correlation between the total PES/WES and the VAS score for the first premolar was not statistically significant. Conclusions: The PES/WES is an objective tool in rating the esthetics of implant supported single crowns and adjacent soft tissues. Orthodontists were the most critical observers, while periodontists were more generous than other observers. The statistical analysis revealed a statistically significant correlation between patients' esthetic perception and dentists' perception of the anterior tooth.
