  • Transplantation of one's own teeth from one site to another is called dental autotransplantation. The role of autotransplantation of teeth in several clinical situations, the clinical techniques involved and factors influencing success of the transplant are discussed. Autotransplantation of impacted or retained teeth is an appropriate treatment, if orthodontic traction has failed, especially in growing patients.

  • Autotransplantation of tooth has recently become a combined method with orthodontic therapy. With the use of autotransplantation, it has become possible for orthodontists to solve complicated problems in the dental arches. Autotransplanted teeth showed the same development as their contralaterals with respect to both eruption and root growth. This indicates that autotransplantation and orthodontic treatment is a method that should be considered in case of impacted, missing, or malformed teeth. In this report two cases are presented to demonstrate that orthodontic treatment with autotransplantation can contribute to more satisfactory solution to the problem for impacted teeth.

  • Purpose: Many clinical studies have reported that higher success rates are achieved with teeth that have immature roots than other autotransplanted teeth that have more immature root. However, based on date published recently, the success rate of autotransplantation of teeth with complete root formation was higher. The purpose of this study was to examine the long term(2 to 6 years follow-up) success rate of autotransplantation of third molar with complete root formation and to discuss some conditions and prerequisites for success. Materials and Methods: 26 sites of 24 patients aged 26 to 55 (mean age 40.8) were autotransplanted with third molars with complete root formation. These cases were followed for 2 to 6 years after surgery. The success criteria included (1) no discomfort during functioning (2) absence of progressive root resorption and alveolar bone resorption. Result: Of 26 teeth 5 teeth were failed, therefore success rate is 81%(21/26 teeth). The results suggested that higher success rate is acquired from (1) extraction socket due to dental caries (2) mandibular recipient site (3) patient younger than 40 years old. Autotransplantation of third molar to replace molars with advanced periodontal disease also showed considerably high success rate(84%). Conclusion: With appropriate case selection, autotransplantation of third molar with complete root formation remains a viable alternative for replacing a missing molar tooth.

  • The extracted right mandibular third molar of a 37-year-old man was transplanted into the first molar area, and a bone graft procedure using autogenous tooth-bone graft material was performed for the space between the root and the alveolar socket. Reattachment was achieved after 10 months. Therefore, autogenous tooth-bone graft material is considered reasonable for bone induction and healing in the autotransplantation of teeth.

  • Purpose: Dentigerous cyst is the most common intra-osseous lesion of the jaw. Dentigerous cysts can cause delays in eruption of the affected permanent tooth in mixed dentition. It has been suggested that the affected permanent tooth could be erupted spontaneously after the dentigerous cyst was enucleated. But in some cases, orthodontic treatment or autotransplantation technique is known to be required. This study reviews previously performed prognoses of affected permanent teeth, which will lead to a more efficient treatment plan. Patients and Methods: With 28 patients who have undergone cyst enucleation and 10 patients who have undergone autotransplantation, the prognosis of permanent teeth was observed. Results: After cyst enucleation, spontaneous eruption of a permanent tooth was observed in 56.3% patients, orthodontic treatment was performed in 25% patients. The success rate of autotransplantation was 60.0%. Discussion: The first choice for treatment of dentigerous cyst in mixed dentition is to guide spontaneous eruption of permanent teeth. For cases without enough eruption space, the orthodontic treatment should be considered. Autotransplantation should be considered when the spontaneous eruption is not expected. It should be considered that the rate of successful autotransplantation is decreased on maxilla anterior area.

  • 임플란트 술식은 그 동안 많은 발전을 하였고, 자연치를 대체할 훌륭한 치료법임에는 부인할 수 없지만 치주인대가 존재하지 않는 구조적 한계점, 발치 직후 시작되는 bundle bone의 흡수는 자연치와 같은 적절한 emergence profile을 만들어내기 어려울 수 있고 이는 심미적인 결과로 이어질 수 있다. 만약 해당 환자의 구강 내에 건전한 제3대구치가 있고, 결손부위의 염증상태가 심각하지 않으면 건전한 제3대구치를 결손된 부위로 이식하여 치아를 재건할 수 있다. 성공적인 자가치아이이식술은 저작기능을 회복하고, 자가치아를 이용하기에 생체 친화적이며, 치조골의 흡수를 예방하는 훌륭한 치료이기 때문에 가능하기만 하다면 첫번째 치료로 충분히 고려될 수 있을 것이다.

  • The autotransplantation procedure were performed for the cases with impacted maxillary anterior teeth, which were thought unrealistic by the treatment with surgical exposure and orthodontic traction into the arches. The results were as follow : 1. As the treatment with autotransplantation is the last resort, the case indicated should be selected cautiously by adequate case analysis. 2. In order to reduce postoperative complication, damages to periodontal ligaments and adjacent bony structures should be minimized by conservative surgical procedures. 3. After autotransplantation procedures, postoperative endodonic treatment and continuous follow-up check with clinical and radiographic examination should be followed. Although the autotransplantation procedure is not the treatment of choice in most cases, it was thought to be a good alternative in certain cases when orthodontic treatment is unrealistic with continuous study to overcome the handicaps.

  • Purposes: The aim of this study was to evaluate pulp healing, periodontal healing, root development of autotransplantation of immature third molars and show its viability in treatment of early loss of tooth in young patients Materials and methods: In this article we performed a retrospective study with 41 transplanted teeth in 36 patients. The Mean age at the time of surgery was 17 years(range $13{\sim}24$ years) and mean postoperative follow up period was 2.4 years(range $1{\sim}6$ years) We evaluated the survival rate, pulp healing, periodontal healing, root development of the above teeth Results: At the last examination 40 teeth among 41 transplants were still present so survival rate was 97.6%. The pulpal healing was found in 38 teeth of 41 transplants. The periodontal healing was found in 38 transplants. The continuous root development was seen in 38 transplants. Conclusions: From the above results, the autotransplantation of immature third molars was found to be a useful and reliable treatment method for early loss of teeth in adolescents and young adults.

  • Treatments for restoring the function and esthetics of missing teeth include fixed bridge, partial denture, orthodontic movement, implantation and autotransplantation. However, there is no absolute indications for each techniques. Due to undevelopment of root and root resorption after autotransplantation, the success rate of autotransplantation over the past decades have been low. Recently. with the study on biological principles of the healing of periodontal ligament, the success rate of autotransplantation began to improve. We report the cases of successful autotransplantation which resulted in ideal healing of periodontal ligament, gingiva and alveolar bone.

  • 상악 견치의 매복은 소아치과 의사가 흔히 접할 수 있는 맹출장애이며, 이를 방치하였을 경우 인접치의 치근 흡수, 낭종 형성 등의 임상적인 문제점을 유발할 수 있다. 이에 대한 치료는 간단한 유치 발치에서부터 매복치아의 교정적 견인, 외과적 자가이식 등 다양한 방법을 고려할 수 있다. 이 중 자가 이식은 매복치아가 교정적 견인술을 시행하기 어려운 위치에 존재하거나 재위치 시키는데 실패했을 경우에 매복치아의 발거에 앞서 고려할 수 있으며, 그 예후는 치근의 완성도, 환자연령, 외과적 술식, 근관치료 시기, 치아고정 기간 등에 의해 결정된다. 본 두 증례들은 혼합치열기 말기에 상악 견치가 매복된 환자에서 그 매복 위치가 자발적인 맹출 유도나 교정적 견인 및 배열이 어렵다고 판단된 경우이며, 자가 이식 후 근관치료와 교정 치료를 시행하고 현재까지 성공적으로 유지되고 있어 보고하는 바이다.
