数字化导板辅助下左上根折中切牙不翻瓣即刻种植即刻自体冠修复1例报告

Analys of a case with immediate implant and autocrown restoration of left upper root incisor without flap assisted by digital guide plate

评估前牙美学区外伤牙在数字化导板辅助下行不翻瓣即刻种植,即刻自体冠修复的临床美学效果,探讨影响美学区种植修复的临床因素。患者左上中切牙因外伤根折,微创拔除患牙后,在数字化导板辅助下行不翻瓣即刻种植,并当日采用自体冠行即刻临时修复,6个月后制备个体化取模柱行精确取模,完成个体化全瓷基台-氧化锆全瓷冠修复。在18个月的随访期内,本病例获得了良好的“红白”美学修复效果,影像学检查显示种植体周围骨结合良好,边缘骨水平无吸收。该病例表明在数字化导板辅助下,美学区外伤牙行不翻瓣即刻种植,即刻自体冠修复,可以获得良好的“红白”美学修复效果。

This case report was aimed to evaluate the clinical aesthetic effect of immediate implant without flap and autocrown restoration for traumatic teeth in the aesthetic area of anterior teeth assisted by digital guide plate,and explore the clinical factors affecting implant restoration in the aesthetic area.After minimally invasive extraction of the affected tooth due to traumatic root fracture of the patient's left upper central incisor,immediate implantation without flap was performed under the assistance of digital guide plate,and immediate temporary restoration was performed with autogenous crown at the same time.Six months later,personalized mold extraction column was prepared for precise mold extraction,and personalized all-porcelain abutment-zirconia all-porcelain crown restoration was finally completed.During the 18-month follow-up period,the patient achieved a good red-white aesthetic effect,and imaging examination also showed good periimplant bone bonding and no absorption at the edge bone level.This case showed that with the assistance of digital guide plate,immediate implantation of traumatic teeth in aesthetic area without flap and immediate autologous crown restoration can achieve good red-white aesthetic effect.
