Alveolar ridge preservation and early implant placement at maxillary central incisor sites: A prospective case series study

Abstract

Purpose: To assess whether alveolar ridge preservation (ARP) with 90% deproteinized bovine bone mineral in a 10% collagen matrix (DBBMC) and resorbable type I/III porcine collagen matrix (CM) maintains sufficient bone volume for early implant placement 8–10 weeks after extraction of maxillary central incisors. Materials and Methods: In this case series study of 10 consecutively enrolled patients, sockets of maxillary single central incisors requiring extraction and early implant placement were grafted with DBBMC/CM. Ridge dimensions were measured pre-extraction and just prior to implant placement. Results: Alveolar ridge preservation maintained sufficient bone volume for implants to be place..
