| 摘 要： | 目的：评价单钉近嵴顶固定颏部骨块移植术在上前牙区骨增量种植中的临床应用和疗效。方法：2013年1—6月收集上前牙区牙槽嵴严重吸收患者5 例，年龄19~24岁，平均21.6岁，其中单牙缺失3例，多牙缺失2例。取患者颏部块状骨，采用单钉近嵴顶固定法行自体骨块移植，术后定期随访。种植体植入术前拍摄锥形束CT（cone beam computed tomography，CBCT），观察移植骨愈合情况，并测量牙槽嵴宽度和钛钉距牙槽嵴顶距离。参考CBCT检查结果，常规完成种植体植入术，待种植体骨结合形成后完成种植修复。结果：5 例自体骨块移植术全部成功，无1 例出现相关并发症。术后上前牙区骨量充足，固定钛钉顶端接近牙槽嵴顶。结论：采用单钉近嵴顶固定法行颏部自体骨块移植能有效改善上前牙区的骨量严重不足，临床疗效良好。

| Abstract: | Objective: The aim of this study was to evaluate the clinical effects of fixation of bone block graft with single titanium screw adjacent to alveolar ridge crest for bone augmentation in maxillary anterior implant treatment. Methods: From 2013.01 to 2013.06, five patients with serious alveolar ridge defect in maxillary anterior zone were collected in this survey. The ages of the patients ranged from 19 to 24 with a mean age of 21.6 years old. Among them, 3 cases lost single tooth and 2 cases lost multiple teeth. Autogenous chin bone blocks were taken and fixed with single titanium screw adjacent to the alveolar ridge crests. Postoperative follow-ups were made periodically. After 6-9 months, cone beam computed tomography (CBCT) was used to evaluate their alveolar ridge augmentations and measure the width of alveolar ridges and the distance from titanium screw to alveolar ridge crest. Based on the CBCT measurements, implants were then inserted. After the osseointegration period, final prosthetic restorations were finished. Results: The successful rate of the bone augmentation was 100% and no relative clinical complications occurred in this study. Adequate bone augmentations were obtained in maxillary anterior areas and the fixed titanium screws were adjacent to the alveolar ridge crest. Conclusion: The augmentation of chin bone block graft fixed with single titanium screw adjacent to alveolar ridge crest is a predictable way to improve bone defects in maxillary anterior areas for satisfactory implant treatments. |
