Using apical surgery to prepare apical bone before immediate implant placement and provisionalization in esthetic zone-a case report

摘要

Due to high satisfaction, immediate implantation has been an attractive treatment option for many patients nowa- days. 1 Immediate implant placement and provisionalization (IIPP) may contribute to a more promising result. 2,3 How- ever, the indications for IIPP are quite strict that not all the cases may match. 4 Primary stability, sufficient bone volume and proper implant position are critical factors to the reliable osseointegration, satisfactory esthetic and func- tional outcome. In other words, some endodontic failure or vertical root fractured cases that result in significant bone loss may not be appropriate for IIPP. Here, we presented a case performing periapical surgery combined with guided bone regeneration to create a good foundation for IIPP in the esthetic zone.
