The aim of this study was to evaluate implant stability placed in the maxillary sinus which was augmented with bovine bone mineral (Bio-Oss) mixed with autogenous bone from the maxillary tuberosity. Maxillary sinus floor augmentation with the mixture of bovine bone mineral and autogenous maxillary tuberosity bone was performed in 30 maxillary sinuses, and 68 implants were placed at the time of sinus graft. After 6 months of implant placement abutments were connected and implant stability quotient (ISQ) was measured by radio frequency analysis (RFA). In addition, bone level changes was evaluated by taking periapical radiograph. During surgical procedures, no complication was observed, and all patients healed uneventfully. At 6 months the implant showed stable ISQ values. The marginal bone level changes around the fixtures was stably maintained through out the follow up period. This study confirmed that maxillary sinus floor augmentation with mixture of bovine bone mineral and maxillary tuberosity bone could be reliable for bone regeneration in subantral space.

This study investigated the mandibular fractures that were treated at the Seoul National University Boramae Hospital in order to analyze the characteristics of mandibular fractures and the relationship between the causes and injury patterns. A total of 141 patients with mandibular fractures who were treated between 1996 and 2004 were analyzed retrospectively. The male to female ratio in the patient group was 5.13:1, and the mean age was 33.7 years. The most common etiologic factor was assaults (45.4%), and which was followed by activities associated with daily-life (40.4%) includeding falls, stumbling, collisions, and traffic accidents (11.3%). Single fracture sites were present in 75 patients (53.2%), two or more fracture sites were observed in other patients, and a total of 211 fracture sites were observed. The mandibular angle fractures (46.7%) was the most common in case of single fractures, and symphysis and angle fractures (45.4%) was most common in multiple fractures. Through out overall fracture sites, the most common fracture site was the symphysis (41.2%), followed by the angle (32.2%) and condyle (18.5%). Among assault and falls-related injuries, the common involving sites were the symphysis, and followed by the body and condyle. In case of traffic accidents, the symphysis fracture was the most common, and which was followed by the condyle and angle fractures. This study documented the characteristics of the mandibular fractures. The results demonstrate that preventive measures according to these characteristics will need to be implemented in order to minimize the risk of maxillofacial injuries. 저자 등은 1996년 1월부터 2004년 12월까지 서울대학교 보라매병원 구강악안면외과에서 치료받은 141명의 하악골 골절 환자의 임상적 연구를 통하여 다음을 알 수 있었다. 1. 전체 환자에서 남,녀 성별 발생빈도는 5.13대 1로 남자에서 호발 하였으며, 연령대별로는 20대에서 가장 빈발하였고 (30.5%), 그 다음 30대, 40대 (22.7%) 순이었다. 2. 하악골 골절의 원인으로 폭행 (45.4%), 낙상, 추락 및 충돌 (40.4%), 교통사고 (11.3%) 순이었다. 3. 골절부의 위치는 하악 정중부 (41.2%), 우각부(32.2%), 과두부 골절(18.5%)의 순으로 나타났으며, 단일 골절의 경우 하악 우각부 골절이 (46.7%)로 가장 많았고, 두 군데 이상의 골절의 하악 정중부 및 우각부 동시 골절이 가장 많았다 (45.5%). 4. 교통사고로 인한 하악 골절은 정중부, 과두부, 우각부 골절의 순으로 발생 빈도를 보였고, 폭력과 낙상, 추락 및 충돌 등으로 인한 골절의 경우 정중부, 우각부, 과두부 골절 순으로 발생빈도를 보였다.
