目的:研究即刻种植与延期种植骨结合种植体的临床成功率。方法:门诊牙种植病例104例,植入种植体114颗。其中即刻种植组48例,男27例,女21例,年龄47.1+1.9岁,植入56颗种植体;延期种植组56例,男33例,女23例,年龄46.7+1.9岁,植入58颗种植体。修复后1年随访,观察两组病例种植体保存率,牙龈美学评价,X线片骨吸收检查。结果:即刻种植组56颗种植体中1颗由于邻牙根尖周感染形成脓肿,2个月后种植体脱落,1颗因术中发现患牙拔除后无可利用的种植骨量,充填骨粉后完成种植手术,其余病例均愈合良好。术后1年随访,即刻种植组保存率96.4%,延期种植组保存率100%。结论:尽管即刻种植组的保存率低于延期种植组,但是缩短了患者的就诊时间和就诊次数,同样可以取得良好的功能与美学效果,具有很好的临床效果。
OBJECTIVE: To study the clinical success rate of implants with immediate implant and dendritic implant. Methods: 104 cases of dental implants were implanted and 114 implants were implanted. Among them, 48 cases were implanted immediately, including 27 males and 21 females, aged 47.1 + 1.9 years and implanted 56 implants. There were 56 males and 33 females with an average age of 46.7 ± 1.9 years 58 implants. One year follow-up after repair, the implant preservation rate, gingival aesthetic evaluation and X-ray bone resorption were observed in two groups. RESULTS: One of the 56 implants in the immediate implant group developed an abscess due to the apical periapical infection. After 2 months, the implants fell off. One of the implants was found to have no available bone mass after tooth extraction and filled with bone meal Complete planting surgery, the rest of the cases healed well. One year follow-up showed that the immediate preservation group had a 96.4% preservation rate and the post-implantation group had a 100% preservation rate. Conclusion: Although the preservation rate of immediate implant group is lower than that of deferred planting group, it can shorten the treatment time and number of visits, and also can obtain good functional and aesthetic effect, which has good clinical effect.
