  • 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.

  • 최근 들어 치아의 심미적 개선을 위해 전치부 심미 보철물을 제작하는 치료를 진행하는 경우가 있는데, 이 때 심미적인 요소에 치중하여 생물학적, 기계적 요소를 간과하기 쉽다. 이로 인해 중립대 공간 및 치열에 변화가 발생하고, 혀와 구순의 위치가 변화하고, 교합 및 전방유도 변화로 인해 부정확한 발음문제가 유발될 수 있어 이에 대한 체계적인 진단 및 치료과정에 대한 고려가 필요하다고 사료된다. 본 증례에서는 10년 전 제작한 고정성 보철물로 인해 부정확한 발음 및 비심미성으로 불편감을 호소하는 환자에서 음향학적 분석, 심미적 분석, 교합, 중립대 라는 4가지 요소를 이용하여 체계적인 진단 및 치료과정을 통하여 보철물을 재수복하였고, 이에 기능적, 심미적 회복을 도모하여 환자와 술자 모두에게 만족스러운 결과를 얻었기에 보고하는 바이다.

  • 심하게 위축된 하악 치조제의 경우, 총의치의 통상적인 기능인상 과정을 통해서는 의치의 적절한 유지력과 안정성을 얻기가 어려울 수 있습니다. 이러한 환자에서는 중립대 인상기법을 사용하는 방식이 효과적인 대안이 될 수 있습니다. 중립 영역은 근육 신경계의 정상적인 구강 기능 동안 입 바깥쪽으로 향하는 혀의 압력과 안쪽으로 향하는 뺨과 입술의 압력이 균형을 이루는 영역으로 정의됩니다. 중립 영역 인상을 통해 만들어진 총의치는 유지력과 안정성을 향상시킬 뿐만 아니라 구치 부위에 적절한 혀 공간을 제공합니다. 또한 인공치아 주변 부위의 음식물 찌꺼기가 줄어들고 적절한 안면 지지대를 통해 미관이 개선됩니다.

  • PURPOSE. The aim of this study was to assess the esthetic outcome of maxillary anterior single implants by comparing the esthetic perception of dental professionals and patients. MATERIALS AND METHODS. Twenty-three patients with single implants in the esthetic zone were enrolled in this study. Dentists of four different dental specialties (Three orthodontists, three oral surgeons, three prosthodontists, and three periodontists) evaluated the pink esthetic score (PES)/white esthetic score (WES) for 23 implant-supported single restorations. The satisfactions of the patients on the esthetic outcome of the treatment have been evaluated according to the visual analog scale (VAS). RESULTS. The mean total PES/WES was $12.26{\pm}4.76$. The mean PES was $6.45{\pm}2.78$ and mean WES was $5.80{\pm}2.82$. There was a statistically significant difference among the different specialties for WES (P<.01) and Total PES/WES (P<.01). Prosthodontists were found to have assigned poorer ratings among the other specialties, while oral surgeons gave the higher ratings than periodontists, orthodontists, and prosthodontists. CONCLUSION. Prosthodontists seemed to be stricter when assessing aesthetic outcome among other specialties. Moreover, a clear correlation existed between dentists' and patients' esthetic perception, thereby providing rationales for involving patients in the treatment plan to achieve higher levels of patient satisfaction.

  • 임플란트 식립시기가 심미적인 부분에 영향을 미치는 것에 대한 연관성을 평가하기 위해 전치부 영역에 식립된 34개의 임플란트 (27명 환자)를 후향적으로 조사했다. 즉시, 조기 및 지연식립으로 시기별로 그룹을 나누고 모든 환자를 보철완료 1년후에 연조직 평가를 시행했다. 통계적으로 그룹별 유의한 의미는 없었다. 식립 시기에 상관없이 만족할 만한 최종결과를 위해 다양한 골이식술과 연조직 이식술이 이루어졌다. 즉, 식립시기로 그 결과를 결정지을 수 없다는 점은 다각적인 면에서 고려사항이 요구된다는 점을 시사한다.

  • Reports have it that horizontal and vertical loss of the ridge happens during 6 months after tooth extraction. So valuable ridge preservation techniques are often necessary in the maxillary anterior areas. Maintaining and/or increasing blood supply and stability is essential to graft survival. The objective of this study was to determine the effect on extraction socket seal of pedicle subepithelial connective tissue graft with tunneling on maxillary esthetic zone through healing state for 8 weeks.
