根盾技术在前牙美学区即刻种植中的应用进展

摘要/Abstract

摘要：

前牙区修复存在的美学问题一直受到广泛关注,牙齿拔除后唇侧牙槽骨的吸收可导致轮廓塌陷。即刻种植术虽然能一定程度上减少骨吸收量,但不能达到理想的美学效果。根盾技术是指通过保留患牙唇侧一定厚度和形态的健康牙根片,形成牙根-牙周膜-牙槽骨复合体,以维持牙槽嵴厚度、防止牙槽嵴吸收的一种技术。本综述就根盾技术的分类、临床要点、并发症的处理等方面进行回顾,旨在为临床医师在美学区种植修复中合理应用该技术提供参考依据。

Abstract:

The resorption of labial alveolar bone after tooth extraction remains a major aesthetic concern in anterior restorations, as it may cause facial profile collapse. Although immediate implants can reduce the amount of resorption to a certain extent, they cannot achieve the desired result. The socket-shield technique can maintain the thickness of the alveolar ridge and prevent resorption by retaining healthy root fragments with a certain thickness and shape on the labial side of the implant site to form a root-periodontium-alveolar bone complex. This review provides an overview of the classification, clinical aspects, and management of complications of the socket-shield technique. It aims to provide reference for clinicians to wisely use this technique in aesthetic implant restorations.

Key words: socket-shield technique, immediate implant placement, soft and hard tissue preservation
