早期种植的临床应用观察

Clinical application of early implant placement

目的：探讨早期种植临床应用特点，并初步观察临床效果。方法：28例患者30颗牙缺失4-8周后，植入30枚Straumman软组织水平种植体，术后3个月后行永久性修复。随访6-36个月，修复后平均追踪观察时间为22个月，观察方法为临床检查和x线检查。结果：30枚种植体留存率100%，未发生严重并发症。种植体颈部边缘骨吸收均小于1mm，唇颊侧软组织未发生明显退缩。结论：早期种植可以缩短种植修复时间，并取得较好的临床效果。

Objective： To explore the clinical application characteristics of early implant placement and evaluate the clinical results. Methods： 28 patients with 30 teeth missing for 4-8 weeks were treated with 30 Straumman soft tissue level implants,and final prostheses were performed after 3 months.The mean follow-up time was 22 months （6-36months）. Clinical examination and X-ray were conducted. Results： No implant was lost or serious complications occurred in observation period. Marginal bone resorption was less than 1mm, there was no significant recession of labial and buccal gingival.Conclusion：Early planting can shorten treatment time, and esthetic outcomes could be achieved.
