Immediate implant placement and provisionalization has been considered as a preservative procedure when replacing failing teeth, especially in the esthetic zone. Nevertheless, an average facial gingival tissue recession of 1 mm is still common after one year of function. Furthermore, facial gingival recession of thin periodontal biotype seems to be more pronounced than that of thick biotype. Biotype conversion around both natural teeth and implants with subepithelial connective tissue graft has been advocated, and the resulting tissues appear to be more resistant to recession. A technique combining subepithelial connective tissue graft and immediate implant placement and provisionalization is devised to achieve a more stable peri-implant tissue in thin biotype situations. This article describes the surgical and prosthodontic approach of this procedure as well as its clinical rationale.
即刻种植并临时修复被认为是替换患牙时的一种保留性操作，尤其是在美学区域。然而，在功能行使一年后，平均1mm的面部牙龈组织退缩仍然很常见。此外，薄牙周生物型的面部牙龈退缩似乎比厚生物型更明显。有人主张用上皮下结缔组织移植来实现天然牙和种植体周围的生物型转化，并且由此产生的组织似乎对退缩更具抵抗力。为了在薄生物型情况下获得更稳定的种植体周围组织，设计了一种将上皮下结缔组织移植与即刻种植并临时修复相结合的技术。本文描述了该操作的手术和修复方法及其临床原理。
