目的:探讨上颌前牙区不翻瓣即刻牙种植术后软硬组织变化情况。方法:回顾性分析上颌前牙实施即刻牙种植术修复病例36例的临床疗效及术后3~6个月前牙种植区软硬组织变化情况。结果:所有患者术后均未出现明显肿胀、疼痛等不良反应,术后3~6个月复查,种植体无松动,存留率为100%,数字化全景机拍摄全颌曲面断层片可见种植体周围新骨形成,未发现透射影。种植修复部位牙龈色泽正常,探诊无出血,牙龈形态美观,无炎症表现。种植后6个月牙槽骨唇侧骨板近远中吸收、近远中牙龈附着退缩值均明显高于种植后3个月,差异具有统计学意义(P<0.05)。结论:前牙区不翻瓣即刻牙种植术临床修复效果满意,能够尽可能保存种植体周围骨组织及软组织高度。
Objective: To investigate the changes of soft and hard tissue immediately after dental implant in maxillary anterior teeth area. Methods: The clinical curative effect of 36 cases of maxillary anterior teeth treated with immediate dental implantation and the change of soft and hard tissues of dental implants 3 to 6 months after operation were retrospectively analyzed. Results: No obvious postoperative swelling, pain and other adverse reactions, 3 to 6 months after the review, the implant without loosening, the survival rate was 100%, the digital panoramic camera to shoot the whole jaw curved surface can be seen around the implant New bone formation, no transmission shadow found. Gingival repair part of normal color, probing no bleeding, beautiful gingival appearance, no inflammation. At 6 months after implantation, the alveolar bone plate was absorbed in the near and far, and the gingival attachment and retraction values in the near and far were significantly higher than those at 3 months after planting. The difference was statistically significant (P <0.05). Conclusion: The results of clinical repair of anterior teeth flap immediate dental implants are satisfactory, and the bone tissue and soft tissue height around the implants can be preserved as much as possible.
