As the number of patients seeking implants increases, so do the esthetic challenges. Adequate bone is necessary to place an implant with an esthetically pleasing outcome. Failing teeth that require implant replacement often have bony deficiencies, and several surgical techniques have been advocated for maintaining bone volume at the time of extraction. This case report utilized a predictable conservative technique for treating a facial bony defect prior to implant surgery. Atraumatic flapless tooth extraction and the placement of a resorbable collagen membrane and mineralized allograft allowed for adequate regeneration of the alveolar socket prior to implant placement. The dentition was later restored with a zirconia abutment and crown. Socket repair utilizing this technique was a clinically acceptable method for obtaining an esthetic implant restoration.
随着寻求植入物的患者数量增加，美学挑战也随之增加。要有美观的植入效果，充足的骨量是植入的必要条件。需要植入物替代的缺失牙往往存在骨量不足的情况，并且已经提倡了几种外科技术来在拔牙时维持骨量。本病例报告采用了一种可预测的保守技术，在种植手术前治疗面部骨缺损。无创无瓣拔牙以及放置可吸收胶原膜和矿化同种异体移植物，使得在植入种植体之前牙槽窝能够充分再生。随后用氧化锆基台和牙冠修复牙列。利用该技术进行牙槽窝修复是获得美观种植修复的一种临床可接受的方法。
