저자 등은 하악골에 발생한 범랑아 세포종 1례에서 금속망을 이용하여 장골능으로 부터 채취된 PMCB와 피질골을 혼합하여 장착시키는 방법으로 이차적 하악골 재건술을 시행하여 하악골의 기능 및 심미적 측면에서 양호한 결과를 얻었다. 그러나 향후 금속망의 제거가 필요하며, 골수와 함께 이용된 피질골을 효과에 대한 실험적 연구가 요구된다 하겠다.

Reconstruction of defect in the anterior part of the maxilla to enable implant placement or prothesis is a complicated treatment due to the anatomical position and lack of soft tissues. Two cases are presented in which autogenous iliac PMCB(particulate marrow and cancellous bone) with titanium mesh were used for premaxilla reconstruction and alveolar bone repair of the anterior maxillas prior to denture and implants fixation respectively. Cancellous bone from the anterior iliac crest was compressed and placed against a titanium mesh fixed to the bone of palate in a patient with severe defect of the anterior maxilla. There were no problem in the healing, and the anterior maxillas of two patients had increased height and width during the initial healing and remodeling. The clinical reports describe the use of titanium mesh for reconstruction of premaxilla. Autogenous bone grafts were harvested from the iliac crest and were loaded on a titanium mesh that were left in the patient's maxilla for 6 months before they were removed respectively. The radiographic analysis demonstrated that a 10mm vertical ridge augmentation had been achieved. In guided bone regeneration, the quantity of bone regenerated under the barrier has been demonstrated to be directly related to the amount of the space under the membrane. This space can diminish as a result of membrane collapse. To avoid this problem which involved the use of a titanium mesh barrier to protect the regenerating tissues and to achieve a rigid fixation of the bone segments, were used in association with autologous bone in 2 cases. The aim of this study was to evaluate the capability of a configured titanium mesh to serve as a mechanical and biologic device for restoring a vertically defected premaxilla.

외상이나 감염 또는 종양의 적출에 의해 발생한 하악골 결손부는 심미적, 기능적으로 많은 문제를 야기한다. Sykoff가 1900년에 자가골 이식으로 하악골 결손부를 수복한 이후 현재까지 많은 이식물과 이식 방법이 이용되어져 왔으며 특히 늑연골은 1920년에 Gillies에 의해서 TMJ 수복에 처음 사용된 이후 성장기 아동의 과두결손부 수복에 많이 이용되고 있다. 또한 자가장골은 안면부의 수복에 보편적으로 이용되고 있는 공급부위이며 특히 많은 양의 망상골이 필요한 경우에는 후방 접근법을 이용함으로서 충분한 양의 골을 얻을 수 있다. 수복의 시기는 환자마다 차이가 있어서 나이, 과거력, 초기질별의 상태, 성장발육정도 및 심미적, 정신적인 면을 고려하여야 하며 악성종양의 제거시에는 재발여부와 방사선 치료 등을 고려하여 적절한 시기를 선택하여야 하나, 일반적으로 술후 약 1-2년 후에 시행할 수 있다. 본원에서는 하악골 골육종으로 진단된 15세 남자 환자에서 과두를 포함하는 좌측 하악골 절단술후 임시로 레진수복물을 장착한뒤 약 20개월간의 주기적인 검진결과 재발의 기미가 없어 늑연골과 장골의 복합이식을 통하여 심미적, 기능적으로 양호한 결과를 얻었기에 그 증례를 보고하는 바이다.

In cases of severe alveolar bony resorption in the edentulous posterior maxillae, implant placement is limited anatomically due to maxillary sinus. If the ridge is atrophic, the various bone grafting methods are required for the ridge augmentation. But the result of the onlay grafting procedure is not always promising. On the posterior maxilla, maxillary sinus mucosa lifting and bone grafting into the sinus floor, subantral augmentation(SA) technique are recommended. Various SA procedures have been developed for implant installation. We perfer to simultaneous block bone graft and implant installation through the residual alveolar ridge into the grafted block bone to fix the grafted bone and to gain the primary stability of the installed fixture. When a sagittal skeletal discrepancy in present due to the severe alveolar bony resorption of the maxilla, the advancement of the maxilla by Le Fort I osteotomy simultaneously with installation of implant fixtures combined with sinus lifting and interpositional bone graft procedure can be indicated. We applied various SA techniques for implant installtion to the 46 edentulous posterior maxillae, and total 154 implants were installed at our department from 1992 to 1999. Various SA techniques were classified in detail and the indications of each techniques were discussed. The changes of residual bony height following SA procedure were studied. The results were as follows. 1. The SA procedure combined with bone graft and simultaneous fixture installation were performed in 41 cases, 126 fixtures were installed and 5 fixtures were removed out of them. Le Fort I osteotomy procedure combined with sinus lifting and interpositional bone graft simultaneous with fixture installation were performed in 5 cases. Total 28 fixtures were installed and 2 fixtures were removed so far. 2. Autogenous block bone graft into sinus floor were performed in 35 cases, autogenous particulated marrow cancellous bone(PMCB) graft in 9 cases, and demineralized human bone powder in 2 cases. The donor site for bone graft were anterior iliac bone in 39 cases, posterior iliac bone in 3 cases and mandibular symphysis in 1 case and mandibular ramus in 1 case. 3. In 9 cases with which SA procedure had been performed with the block bone graft, the change of pre- and postoperative residual bony height were measured using MPR(multiplanar reformatted)-CT. The mean residual bony height was 8.0mm preoperatively, 20.2mm at 6 months following up operation and we gained average 12.2mm alveolar bony height. So, we can recommend this one-stage subantral augmentation and fixture installation technique as a time conserving, safe and useful method for compromised posterior edentulous maxilla.
