  • Purpose: Fibrous dysplasia is related to the mutation of gene encoding the alpha-subunit of a signal-transducing G-protein and has variable clinical course. Operation can be performed to prevent functional disorder or structural deformity. After curettage, autologous bone graft were used to fill the defects after curettage. The aim of this study is to compare the result of autogenous cancellous bone grafting and allogenic bone grafting for fibrous dysplasia. Materials and Methods: Among the patients who visit our hospital during the period of April, 1997 to October, 2013, we selected 34 patients who diagnosed fibrous dysplasia and visited our clinic over 1 year. There were 13 males and 21 females. Average age was 26.4 (range 2 to 57) years old. Autogenous bone graft (group I) in 5 cases, Non-autogenous bone graft (group II) in 30 cases. Iliac bone is used in all cases of autogenous bone graft. There were no significant difference in age, follow-up period, preoperational laboratory finding between two groups. Radiographic image was done to evaluate the recurrence of fibrous dysplasia or secondary degeneration. Results: There were four cases in recurrence (group I: 1 case, group II: 3 cases, p=0.554). In all recurrent cases, reoperations were done using curettage and autogenous iliac bone graft. There was no re-recurrence after reoperation. One case of secondary aneurysmal bone cyst was confirmed (group II) and 1 cases of pathologic fractures had developed (group I: 0 case, group II: 1 cases, p=0.559). No malignant change occurred. Conclusion: There were no significant difference between autogenous bone graft group and non-autogenous bone graft group. Our result suggested that autogenous bone graft seems to be good method to treat fibrous dysplasia, in the case of small volume of tumor lesion or non-weight bearing portion.

  • The success of autotransplantation depends on the viability of periodontal ligament in the transplanted tooth. Mechanical injury to periodontal tissues frequently results in dental root resorption and ankylosis, which leads to the failure of transplantation. Enamel matrix derivative(EMD) Which contains several enamel matrix protein (amelogenin family) has been reported to be effective in some periodontal therapies has been recently used to induce periodontal regeneration. EMD promotes proliferation of periodontal ligament cells and is suggested to be useful for transplantation. In this case, we report a clinical case of EMD application in the transplantation of an impacted and immature tooth of a 14 year-old girl to enhance the periodontal regeneration.

  • Autotransplantation of third molars with completely formed roots is known to be effective and provide a high long-term success rate. However, in case of severe mobility or unexpectedly extraction is observed during the monitoring period after surgery, it is generally considered as a failure. This case report describes successful replantation of autotransplanted mature third molar into surgically created molar socket. 1 year follow up of transplanted tooth showed clinically normal periodontal pocket depth and tooth mobility. Root resorption or bone loss were not observed. Provided that there is no apparent sign of inflammation, re-insertion into socket is a viable alternative to immediate determination of extraction.

  • Purpose: This study was performed to evaluate the effi ciency of Platelet-rich plasma (PRP) for acceleration of bone healing process on allograft transplantation after curettage in benign bone tumor. Materials and Methods: From December 2007 to February 2009, twenty-one patients who had benign bone tumor and underwent allograft transplantation after curettage were evaluated. Mean follow-up period was 14.6 months (range, 12-26 months). We compared with 13 cases of PRP group and 8 cases of non-PRP group in terms of size of lesion, bone resorption, amount of applied PRP and complications. The mean age at surgery was 23.6 years (range, 4-73 years). The most common diagnosis was simple bone cyst (7) followed by enchondroma (4), giant cell tumor (3), undifferentiated benign bone tumor (3) and so on. Results: The mean size of lesion was 33.5 $cm^3$ (range, 2.3-181.9 $cm^3$) (29.4 $cm^3$ in PRP group and 40.2 $cm^3$ in non-PRP group). The mean volume of injected PRP was 7.4 cc (range, 3-12 cc). Bone union started at 3.0 months (range, 1.5-5.8 months) in PRP group and 5.3 months (range, 4-8 months) in non-PRP group. Three cases for each group were excluded due to recurrence and pathologic fracture. One patient had febrile episode 3 weeks later after surgery which subsided with antibiotics. Conclusion: The PRP could accelerate bone union in allograft transplantation after curettage of benign bone tumor. Furthermore, we expect that PRP can accelerate bone union in fracture or non-union.

  • Numerous therapeutic approaches are available for impacted teeth, including orthodontic retraction, implantation, and autogenous tooth transplantation. Autotransplantation is a promising method, especially for juvenile patients, as it enables preservation of the function of the periodontal tissues, as well as continued alveolar bone growth. This report describes autotransplantation in two cases in which the tooth was fully-ectopically impacted. With case 1, an ectopically impacted premolar was extracted and transplanted in an upright position, and regenerative endodontic treatment was performed using a platelet-rich fibrin clot and mineral trioxide aggregate (MTA). With case 2, a calcifying odontogenic cyst with an impacted left mandibular second molar was treated by enucleation. The tooth was transplanted into the proper position 3 months after enucleation, and endodontic treatment was performed using MTA. In both cases, autotransplantation appeared to provide a simple and rapid treatment option for patients with ectopically impacted teeth. These cases demonstrate that autotransplantation of ectopically impacted teeth is a viable treatment option rather than implant placement or prosthesis, especially in juvenile patients.

  • 이상과 같이 자가골 이식을 할 때 주의하여야 할 점들을 다루어 보았다. 중요한 것은 어떤 재료를 선택하는 것이 좋은 지가 아니라, 언제 어느 재료로 무슨 방법으로 이식할 것인 지를 결정하는 것이 중요하다. 골이식 수술중에 중요하게 지켜야 할 술기는 피판의 형성과 이식골의 철저한 고정이며 이것이 지켜졌을 때 최대의 효과를 기대할 수 있으며 후유증이나 합병증을 막을 수 잇다. 또한 골이식과 같은 민감한 수술은 모든 조직을 보다 부드럽게 다루어야 한다. 피판을 형성하거나 젖힐 때에도 함부로 당기거나 하여 피판이 찢어지거나 손상받지 않게 하여야 한다. 살아있는 조직을 채취하여 옮기는 이식수술에서 또 하나의 중요한 술기는 수실시간을 단축하는 것이다. 수술의 준비와 기구의 준비를 철저히 하여 총 수술시간을 줄이도록 노력하여야 하며 최소한 이식골을 채취하여 부착하기 까지의 시간은 최소로 줄여야 한다. 골이식 수술에서 무조건 성공하는 특별한 방법은 없다. 위와 같은 여러 가지 주의사항에 유념하고 술기를 발전시켜 좋은 결과를 얻도록 노력하여야 한다.

  • 연골 결손은 자체 치유 능력이 적어 그 크기가 1 cm 이상인 경우 골관절염이 발생할 수 있다. 최근에는 3-tesla MRI 등의 발전으로 인해 수술 전에 미리 연골 손상을 정확히 진단할 수 있어 연골 손상의 치료를 더욱 적극적으로 할 수 있다. 이제까지 연골 손상에 대한 수술적 치료는 세척술(lavage) 및 변연 절제술(debridement), 미세 천공술(microfracture), 자가 골연골 이식술(autologous osteochondral graft), 자가 연골 세포 이식술(autologous chondrocyte implantation, ACI), 동종 골연골 이식술(osteochondral allograft)이 있다.
