REVIEW
Vivianne Chappuis, Mauricio G Araújo, Daniel Buser
The key to achieving pleasing esthetics in implant dentistry is a thorough understanding of the biological processes driving dimensional bone and soft tissue alterations post-extraction. The aim of the present report is first to characterize the extent of bone and soft tissue changes post-extraction and second to identify potential factors influencing tissue preservation in order to facilitate successful treatment outcomes. The facial bone wall thickness has been identified as the most critical factor influencing bone resorption and can be used as a prognostic tool in order to identify sites at risk for future facial bone loss subsequent to tooth extraction...

Progressive alveolar bone resorption after tooth extraction may lead to surgical and prosthetic-driven difficulties, especially when deciding to use a dental implant to replace the extracted tooth. This case report discusses an irreparable lower left second premolar tooth with a periodontal lesion on the buccal side. A preservative tooth extraction was performed. Then, the socket was grafted with bovine bone, a collagen membrane was placed between the buccal bone and the attached gingiva, covering the bone dehiscence buccally, and the socket without a flap was raised...

As implant therapy becomes more commonplace in daily practice, preservation and preparation of edentulous sites are key. Many times, however, implant therapy may not be considered at the time of tooth extraction and additional measures are not taken to conserve the edentulous site. While the healing process in extraction sockets has been well investigated and bone fill can be expected, there are cases where even when clinicians perform thorough debridement of the sockets, connective tissue infiltration into the socket can occur...

Our aim was to describe the postoperative morbidity related to secondary wound healing after coronectomy. Ten of 116 patients treated by coronectomy healed by second intention as a result of failed sutures. We made a retrospective analysis after two years to evaluate the postoperative morbidity related to secondary wound healing. The complete closure of the alveolus of the 10 surgical sites was recorded three months after coronectomy. No patients had postoperative infections, dry socket, or pulpitis. All patients were free of symptoms, the retained roots were completely included, and were not detectable with a periodontal probe...
