Alveolar buccal bone maintenance after immediate implantation with a surgical flap approach: a study in dogs.

This study evaluated buccal bone maintenance after implantation with a surgical flap approach immediately following tooth extraction in a dog model. Mandibular premolars of six dogs were extracted, and threaded implants of 4-mm diameter and 8-mm length with as-machined and dual acid-etched surfaces were placed through balanced procedures in the distal root extraction sockets with a full-thickness flap design. Submerged healing was allowed for 4 weeks, and following euthanization, bone-to-implant contact and buccal and lingual bone loss were evaluated.

Surface treatment at the cervical region and its effect on bone maintenance after immediate implantation: an experimental study in dogs.

Objective: The aim of this study was to evaluate the effect of surface treatment at the cervical region of endosseous dental implants on the alveolar bone remodeling after implantation immediately after tooth extraction in a dog model.

Study Design: The third and fourth premolars of 6 dogs were bilaterally extracted with a full-thickness flap, and threaded implants presenting a textured or a polished surface at the cervical regions were placed on the distal root extraction sockets. Submerged healing was allowed for 4 weeks, and bone-to-implant contact (BIC) and buccal and lingual bone loss were morphometrically measured.
