1933년 Dewey와 Zugsmith가 처음 ovate pontic을 소개한 이후 1990년대 말부터 임상적으로 널리 사용되고 있다. Ovate pontic은 심미적이고 위생적인 자연치의 emergence profile을 더 정교하게 재현할 수 있는 방법으로 알려져 있다. 특히, 상악 전치부가 상실된 경우 발치 시기부터 ovate pontic의 형태를 가진 레진 임시수복물을 제작해 줌으로서 치간유두를 보존시켜 치간공극의 발생을 최소화하여 심미적이고 발음의 이상이 없는 최종보철물을 제작할 수 있다. 본 증례에서는 치아상실부위에서 치간유두의 상실을 최소화하고 자연치와 유사한 emergence profile을 지닌 보철물을 제작하기위해 ovate pontic을 이용하여 처치한 치험예를 문헌고찰과 함께 보고하고자 한다.

Purpose: The emergence profile concept of an implant restoration is one of the most important factors for the esthetics and health of peri-implant soft tissue. This paper reports on two cases of gingival recontouring by the fabrication of a provisional implant restoration to produce an optimal emergence profile of a definitive implant restoration. Methods: After the second surgery, a preliminary impression was taken to make a soft tissue working cast. A provisional crown was fabricated on the model. The soft tissue around the implant fixture on the model was trimmed with a laboratory scalpel to produce the scalloped gingival form. Light curing composite resin was added to fill the space between the provisional crown base and trimmed gingiva. After 4 to 6 weeks, the final impression was taken to make a definitive implant restoration, where the soft tissue and tooth form were in harmony with the adjacent tooth. Results: At the first insertion of the provisional restoration, gum bleaching revealed gingival pressure. Four to six weeks after placing the provisional restoration, the gum reformed with harmony between the peri-implant gingiva and adjacent dentition. Conclusions: Gingival recontouring with a provisional implant restoration is a non-surgical and non-procedure-sensitive method. The implant restoration with the optimal emergence profile is expected to provide superior esthetic and functional results.

환자를 위한 보철물들은 사실 하나도 빠짐없이 'custom'한 보철물입니다. 임플란트보철물 제작시 기성 abutment를 사용한다고 하더라도 최종결과물은 여전히특정 환자만을 위한 'custom'보철물입니다. 환자에게 정말 잘 맞춤(custom)된 보철물을 제작하는데 있어 치과의사와 치과기공사간의 소통과 협업이중요하다는 것은 누구나 알고 있는 사실입니다. 하지만 이러한소통과 협업이 제대로 이루어지려면 먼저 양쪽이 치료방법 및 결과 등에 대한 공통된 임상의 '상식'을 공유하고 있어야 합니다. 아이러니하게도 치과의사와 치과기공사간에 서로 다른 '상식'을 갖고 있음을 확인하게 되는 경우가 의외로 많은 것 같습니다. 임플란트 보철물의 emergence profile은 치주적 건강도나 심미성에 있어 아주 중요한 연결고리임에도 불구하고, 이에 관하여 문헌상에서 명확한 가이드라인이 제시된 바가 없습니다. 자연치아와 임플란트간의 태생적 차이에서 오는 문제들을 인지하고 이를 해결하기 위한 방법들이 치과의사와 치과기공사 모두에게 '상식'으로 공유될 수 있을 때 비로소 환자에게 제대로 맞춤된 보철물이 제작될 수 있습니다.

The objective of this study was to investigate the effects in auditory performance and vocal development of Onomatopoeia and Mimetic Word Productive Training Program in prelingually deafened children with cochlear implantation. The effects were measured with Lip-profile (Listening progress profile: LiP), the number of utterances, vocal developmental level and phonetic inventory. Subjects were four children with cochlear implants who were able to detect speech sounds and environmental sounds. The Onomatopoeia and Mimetic word Productive Training Program was made up of 3 steps with 24 Onomatopoeia and Mimetic words. This study was pre and post design. The results of the study were as follows: First, after Onomatopoeia and Mimetic word Productive Training Program was treated, LiP score was significantly higher. Second, after this program was treated, the number of utterances and emergence of both canonical and postcanonical utterances were increased. Emergence of vowel and consonant Features were increased and diversified. In conclusion, Onomatopoeia and Mimetic Word Productive Training Program appeared to facilitate efficient auditory performance and vocal development.

전치부 치간이개를 치료할 때 가장 어려운 것은 레진으로 축성 후 치아 사이의 "black triangle"없이 치간공극을 메우는 것이다. 이를 위해서는 치경부 형태와 접촉점의 위치에 기초하여 치은 형태를 결정하는 것이 중요하다. 이 증례보고는 적절한 접촉점을 형성하기 위해 비침습적 방법을 사용하여 접촉점의 위치를 설정하였다. 또한 치은-치아 사이에 위치한 Mylar strip을 이용한 기존의 방법을 바꾸어 자연스러운 형태를 갖도록 변형하였다. Mylar strip을 치은연 상방으로 약 1 mm 정도 되게 치은열구에 위치시키고 작은 면구를 치은과 그 사이에 위치시켜 출현윤곽(emergence contour)을 부여하였다. 이와 같은 변형된 방법은 적절한 출현윤곽과 치은형태를 형성하는데 유용하였으며, 임상적용에 유효하였다.

In process of fabrication of a fixed partial denture, dies are trimmed to expose margins of the preparations. The need for the soft tissue cast is quite evident as the soft tissue emergence profile that surrounds the prepared tooth is destroyed in the process of fabrication. This article describes a modified technique to fabricate the soft tissue cast for the conventional fixed partial denture. The impression made with the polyvinylsiloxane was first poured to prepare the die cast. After retrieval of the cast, the same impression was poured second time with the resin based resilient material to cover the facial and proximal gingival areas. The remaining portion of the impression was poured with the gypsum material. This technique does not require additional clinical appointment, second impression procedure, technique sensitive manipulations with impression, or cumbersome laboratory procedures. The simplicity of this technique facilitates and justifies its routine use in fabrication of the fixed partial denture.

Food impaction between the implant prostheses and adjacent teeth is the most frequently observed problem. It may be caused by the migration of the adjacent teeth. This symptom may be observed at the mesial aspect of implant prostheses especially, and related with the multiple contributing factors including teeth vitality and antagonist. Idal proximal contact with optimal strength and shape should be made for preventing the food impaction. Shape of customized abutment and prosthesis should have optimal emergence profile. Long duration from the extraction to the delivery of implant prostheses, the adjacent teeth and antagonist teeth may have possibility of occlusal interferences. Remained teeth mobility can induce the food impaction regardless of interproximal contact strength. Occlusal adjustment to remove occlusal interferences can be a method for enhancing the stability of interproximal contact.

전치부에 발생한 치간이개는 심미적으로 문제를 일으키는 흔한 원인이 된다. "Black triangle"을 생성시키지 않고 치간이 개를 폐쇄시키는 것은 심미치과학에서 도전적 과제 중 하나이다. 전치부 수복치료의 성공 여부는 연조직과 경조직간의 심미적인 연합에 달려있다. 이번 증례에서는 치은-치아 계면에서 자연스러운 외형을 가지는 출현윤곽(emergence profile)을 형성하여 줌으로써 치은의 재생 과정이 일어나 심미적으로 만족스러운 치간이개 폐쇄를 이루어내었기에 이를 보고하는 바이다.

All contours of the restoration not directly related to occlusion are related to the gingival tissues only.And proper contour of restoration is essential for the health of the periodontal tissues.But there are so many controversies about the contour of the restoration, and there is no uniform agreement in the literature as to which contour of restoration is best for periodontium. In general, the contour of restoration means the supragingival contour only but in the case of the intracrevicular restorative procedure the subgingival contour of restoration must be considered. Because a portion of the restoration is placed in a gingival sulcus which is extremely vulnerable to periodontal disease. In this article the concepts or theories of the supragingival contour, the subgingival contour, and the emergence profile were discussed.The contour of the restoration and the biotype of the periodontium must be considered in intracrevicular restorative procedure.And sufficient tooth preparation is important factor to develop the proper contour of restoration which is kind to periodontium.
