摘　　要：目的:观察拔牙后牙槽窝内即刻植骨延期不翻瓣牙种植的临床效果。方法:对23例要求拔牙后作牙种植修复的病例,在拔牙后的牙槽窝即刻植入人工骨粒(Bio-oss或脱钙骨)。3个月后,在植骨位置行临床常规X线和骨量器检查,确定足够的牙槽骨骨量并行不翻瓣牙种植。结果:通过临床和X线观察,植骨后牙槽骨外形丰满,高度和宽度基本保持。不翻瓣牙种植顺利,手术损伤反应小。36颗牙种植体初期稳定性均达30N以上,随访观察6～62个月,种植全部成功。结论:拔牙后牙槽窝即刻植骨,可有效保持牙槽骨外形,提供足够的牙槽骨高度和宽度。在足够骨量基础上行延期不翻瓣牙种植,可简化种植前检查和种植过程,减轻种植局部反应。PURPOSE： To explore and evaluate the clinical outcome of delayed flapless implant placements after bone powder grafted immediately in postextraction sockets. METHODS： 23 patient requiring dental implants after postextraetions were selected for this study. The fresh sockets with at least 3 wails （3 or 4 walls） were immediately grafted and filled with artificial bone powders （Bio-oss and demineralized bone powders）, covered by ultra-thin titanium membranes. Bone graft got to or 2-3mm higher than the top level of the sockets. 3 months later, the alveolar bone heights were checked by routine X-ray examination. And alveolar bone ridge widths were measured by bone-width gauges. The alveolar bones were confirmed sufficient to accommodate the implant with at least 4.0mm in diameter and 9mm in length. Then flapless implant placements were performed. The primary stability of the implants was measured. The implants were followed up and success rate of implant was evaluated. RESULT： The alveolar bone height and width were basically maintained without depression and atrophy through clinical observation and X-ray examination. Flapless implant placements were performed with minor local reaction. The primary stability of 36 implants all attained to 30N. Failure did not happen during a followed up period of by 6-62 months. CONCLUSION： After bone powder grafted immediately in postextraction sockets, sufficient alveolar bone volume for implants can be preserved. Flapless implant placements in sufficient bone support can effectively simplify the preoperative examination and surgical procedures, reducing local reaction. Delayed flapless implant placements after bone powder grafted immediately in postextraction sockets is an effective design and method of dental implantation.
