보철 치료계획 결정과정은 임상정보에 대한 치과의사의 분석과 환자와의 상호소통을 통하여 이루어진다. 치아의 상실이나 치관부 결손으로 인해 발생한 공간으로 반대악 치아가 정출된 경우, 구강기능을 회복시키는데 있어 적절한 치료방법 선택 및 예후를 예측하는데 혼란이 야기될 수 있다. 치아의 정출로 인한 교합평면의 심한 부조화가 나타난 경우, 신중한 평가가 필요하며, 필요 시 교합평면을 재설정 해야 한다. 본 증례는 심한 정출에 의한 불균일한 교합평면과 class III 악간관계로 인한 비심미성 및 저작불편을 주소로 내원한 환자로, 체계적인 진단과정을 통한 치료계획의 수립으로 교합평면 재설정을 통한 전악수복으로 심미적이고 기능적인 결과를 얻었기에 보고하는 바이다.

The purpose of this article is to report a case of internal derangement of TMJ which was successfully managed with surgical and occlusal treatment. The Obtained results were summarized as follow: 1. The patient surgically operated via high condylectomy with meniscoplasty to correct anteriorly displaced meniscus. 2. During operation, the junction area of bilamina zone and meniscus was easily identified and resected using microscopy. 3. The mandible was relocated into therapeutic position with occlusal splint. 4. The occlusal rehabilitation with selective grinding and prosthodontic treatment was done so that the new patient's intercuspal position should correspond to the therapeutic position.

19 years old female had untreated Veau classification class II cleft palate with ectopic eruption of upper right lateral incisor and congenital missing of lower lateral incisors. Upper left lateral incisor, left first molar aid lower left first molar were root restswithperiapicalpathologiclesions. So all root rests were extracted and prosthodontic rehabilitation after orthodontic treatment was planned. She was treated by means of multibanded system with face bow. After 23 months all orthodontic correction were achieved and, as soos as debanding procedure was done she was referred to oral surgeon and prosthodontist for surgical operation and bridge construction.

Partial edentulism has multiple implications in relation to function, esthetics and future rehabilitative treatment. This case report illustrates the management of a patient with extreme consequences of partial edentulism. The main clinical findings were unopposed remaining teeth, overeruption of the remaining teeth, loss of vertical dimension of occlusion, and significant disfigurement of the occlusal plane. Following the diagnostic procedure, a well-coordinated prosthodontic treatment involving liaison with other dental disciplines was indicated. The management involved an innovative combination of fixed and removable prostheses in conjunction with crown lengthening surgery and strategic implant placement. Series of provisional prostheses were applied to facilitate the transition to the final treatment.

This article describes verticsal dimension in its histologic and clinical aspect. Determination of correct vertical dimension of occlusion is one of the most important steps in prosthodontic rehabilitation. It is considered essential for improvement of facial esthetics and stomatognatic functions. Many techniques have been sued for measurement of the vertical dimension in dentulous and edentulous patients : pre-extraction record, physiologic rest position, swallowing, phonetics, esthetics, etc. But, there is no universally accepted or completely accurate method. Though a great deal of energy has been spent trying to find the exact position of the mandible, there is an controversial aspect of vetical dimension.

With the understanding of tooth crown biomechanics and the progress of dentin adhesives, bonded porcelain restorations including a porcelain laminate veneer present an extended spectrum of indications for anterior teeth. Porcelain laminate veneer as a restoration offers the conservative solution that balances the functional and esthetic needs of the anterior dentition. Porcelain's stiffness, its surface characteristics, and the biomechanical strength achieved through bonding to tooth surface enable the restoration of the tooth as a whole supporting occlusal force and masticatory function. Namely, the optical effects inherent in the tooth and the lifelike features of the porcelain make that this restoration approaches the ultimate in esthetic satisfaction for both the dentist and the patient. A 49-year-old female patient with the incisal discoloration of upper central incisors and black triangle between the central incisors was referred to correct her esthetic problems with prosthodontic approach. The patient was satisfied with two porcelain laminate veneers that were made according to prof. Magne and Belser's recommendation.

Prosthodontic treatment planning for various edentulous arches is not an easy issue for dentists. Especially, in case of removable partial denture, we must have a knowledge of overall treatment procedures, and a careful approach is needed. Recently, interest of dental implant and case reports are increasing, the decrease of the removable partial denture is true, but dental implantation takes longer treatment period and it is more expensive. Also, there are still some limitations like lack of available alveolar bone, patient's general condition, and chronic periodontitis. Therefore, sometimes implantation is impossible. Finally, implantation cannot be adapted to every single patient. Currently, the clasp type removable partial dentures are used routinely, giving patients many unesthetic and functional difficulties. With better laboratory technique, removable partial denture with attachment and removable partial denture in rigid type increase patient's happiness level much more than predicted. The case presented in this article, clinically demonstrate the efficiency of using a telescopic system to improve esthetic and functional recovery for patients who lose multiple teeth.

Maxillary obturator prosthesis is the most frequent treatment option for management of partial or total maxillectomy. Heavy weight of the obturators is often a dislocating factor. Hollowing the prosthesis to reduce its weight is the well established fact. The alternate technique to hollow-out the prosthesis has been described in this article which is a variation of previously described processing techniques. A pre-shaped wax-bolus was incorporated inside the flasks during packing of the heat-polymerized acrylic resin to automatically create the hollow space. The processing technique described is a single step flasking procedure to construct a closed-hollow-obturator prosthesis as a single unit. To best understand the technique, this article describes management of a patient who had undergone partial maxillectomy secondary to squamous cell carcinoma rehabilitated with a hollow-obturator prosthesis.

The prosthodontic treatment of severely resorbed edentulous patients has been one of the frustrating areas due to extensive loss of tissues. The integrated neuromuscular balance among tongue, lip, and cheek is compromised. The retention, stability, and support are the three major factors to influence the clinical outcome. Fish described a denture as having three surface, with each surface playing an independent and important role in the over all fit, stability, and comfort of the denture. He recommended that the polished surface should be a series of inclines so that pressure from muscular activity will retain dentures. Within the denture space there is an area that has been termed the neutral zone. The neutral zone is that area in the mouth where, during function, the forces of the tongue pressing outward are neutralized by the forces of the cheeks and lips pressing inward. According to Jacobson and Krol, neuromuscular control interacts to provide retention and the relationship of polished surface of denture base to the surrounding muscular structure of orofacial capsule facilitates the stability and retention. This neutral zone concept has been demonstrated with various modification by a number of authors. The theory used to develop the denture base contours is based on the belief that the muscle should functionally mold not only the border but the entire polished surface. Lott and Walsh reported the clinical success on complete mandibular dentures with application of neutral zone concept. A number of studies demonstrated that denture stability and retention are more dependent on correct position of the teeth and correct contour of external surfaces of the denture in a severely resorbed alveolar ridge. This article presents a prosthodontic approach to treatment of a edentulous patient using neutral zone technique to improve the retention and stability of the prosthesis.

혀는 정확한 근신경계의 조화에 의해 저작, 연하, 발음과 같은 복잡한 기능을 수행하는 데 중요한 역할을 한다. 악성종양으로 인해 구강 내 혀를 절제해야 하는 경우에 환자는 발음 및 연하에 큰 어려움을 겪게 된다. 이러한 환자에 있어 보철적 치료 목표는 저작, 연하 및 발음을 증진시키는 것이다. 보철적 수복 방법은 수술의 종류 및 범위에 의해 결정된다. 완전 혀 절제술(Total glossectomy)을 시행한 경우에는 하악-혀장치(mandibular tongue prosthesis)를 선택하며 악-혀장치(Mandibular tongue prosthesis)는 혀 보철물로 구강저를 채우는 것이다. 이렇게 형성한 혀 보철물은 음식이 식도로 넘어가는 입구(platform)를 형성해주고 발음을 향상시키며 하방의 연약한 이식 조직을 보호하고 외형 및 심리사회적으로 우수하다는 장점을 가진다. 본 증례에서는 완전 혀 절제술(total glossectomy)를 시행한 환자를 위해 보철적으로 수복하는 임상과정을 논의하고자 한다.
