Early implant placement in ridge preserved extraction sockets: A pre?clinical in vivo study

Objectives The aim was to analyse the outcomes of early implant placement after 6 and 12 weeks healing in ridge preserved sites a canine model. Materials methods Implants were placed second maxillary incisors 9 dogs grafting sockets with 90% deproteinized bovine bone mineral 10% collagen matrix (DBBMC) closure resorbable type I/III porcine (PCM). implants randomly assigned (T6) (T12) healing. Results percentage bone-to-implant contact (%BIC), old bone, new residual DBBMC similar between T6 T12. In relation shoulder (IS), original crest (IS-ROB) more apical on buccal than palatal side. regenerated (IS-C) IS-ROB groups. However, distance from IS first bone-to (IS-fBIC) significantly less T12 compared (p = .022; Wilcoxon signed-rank test). bucco-palatal dimensions similar. Conclusions This study confirms that can successfully be incisor are osseointegrated by weeks. There lower IS-fBIC values at aspect. underwent greater corono-apical resorption crest. %BIC, relative proportions mineralized tissues alveolar demonstrated stability
