BACKGROUND
Implant surgery has become popular with the advance of surgical techniques such as sinus lifting, guided bone regeneration, and block bone graft. However, there were no data about the frequency of bone graft during implant surgery. The purpose of this study was to report the frequency and types of bone graft depending on dental implant patients' profile to complement the database regarding implant surgery.
METHODS
The implant operations had been performed from January 2006 to October 2014. The upper and lower jaws were divided into six sextants. A total of 792 sextants were included in this study. Patient information including sex, age, sites, bone graft, and types of bone were investigated.
RESULTS
A total of 1512 implants had been placed. Male and female sextants were 421 and 371, respectively (M:F = 1:0.88). Average age was 54.3 (ranging from 20 to 88 years old). Implants were placed in the posterior maxilla (322 sextants, 40.7 %), posterior mandible (286 sextants, 36.1 %), anterior maxilla (127 sextants, 16.1 %), and anterior mandible (57 sextants, 7.2 %). Bone graft was performed in 50.3 % of the sextants. Among the bone grafted sites, sinus lifting with lateral approach (22.1 %) and guided bone regeneration (22.7 %) were performed most frequently.
CONCLUSIONS
Bone graft in implant surgery was necessary to augment defects. More than half of the sextants needed bone graft for implant installation.
背景
随着诸如上颌窦提升、引导骨再生和块状骨移植等外科技术的进步，种植手术越来越受欢迎。然而，关于种植手术中骨移植频率的数据尚无报道。本研究的目的是根据牙种植患者的情况报告骨移植的频率和类型，以补充有关种植手术的数据库。
方法
种植手术于2006年1月至2014年10月进行。上下颌被分为六个象限。本研究共纳入792个象限。调查了患者的性别、年龄、部位、骨移植情况及骨的类型等信息。
结果
共植入1512颗种植体。男性和女性的象限分别为421个和371个（男：女 = 1:0.88）。平均年龄为54.3岁（范围为20至88岁）。种植体植入上颌后部（322个象限，40.7%）、下颌后部（286个象限，36.1%）、上颌前部（127个象限，16.1%）和下颌前部（57个象限，7.2%）。50.3%的象限进行了骨移植。在进行骨移植的部位中，外侧入路上颌窦提升术（22.1%）和引导骨再生术（22.7%）最为常用。
结论
种植手术中的骨移植对于增加骨缺损是必要的。超过一半的象限在种植体植入时需要进行骨移植。
