1、环状植骨术同期牙种植临床效果的短期观察［摘要］目的观察环状植骨术后的临床效果并总结其手术操作要点。方法15例牙槽骨量严重不足的患者接受环状植骨术并同期植入种植体，术后5个月后行上部修复。分别于术前和术后4个月拍摄锥形束CT,测量牙杷I骨增加的高度和唇舌侧骨吸收量。冠修复后4〜6个月对其牙龈附着水平、牙间乳头分级和牙周探诊深度(PD)进行测量分析，统计骨环的成活率及种植体的存留率，同时观察术后并发症并了解患者的满意度。结果术后4个月复查，骨环成活率为94.4%,种植体的存留率为100%；增加的垂直骨量为(6.06±1.06)mm,骨吸收量为(1.33±0.8
2、4)mm；种植体颈部中心唇舌向的骨宽度为(6・94±0.73)mmo冠修复后4〜6个月随访时,增加的垂直骨量为(5.62±1.03)mm,骨吸收量为(1.51土1.02)mm,种植体颈部中心唇舌向的骨宽度为(6.77±0・72)mmo种植牙和邻牙的卩D无明显差异(卩＞0.05)。术后无明显的并发症，修复效果好,患者满意度高。结论环状植骨术同期植入种植体，手术操作相对容易，疗程缩短，近期效果可靠，远期效果有待进一步观察。［关键词］骨环；即刻种植；自体骨移植［中图分类号］R783［文献标志码］A［doi］10.7518/hxkq.2014.01.010Shor
