Using synthetic biomaterial to fill peri-implant defects (gap) in immediate implants

Osseointegrated implant placement requires proper bone volume, however, tooth extraction requires different standards of bone resorption and bone remodeling. Alveolar ridge resorption has been considered an inevitable consequence of tooth extraction and may be a significant issue for Implantodontics. Despite immediate implant placement, the edentulous site of the alveolar process undergoes substantial bone remodeling, with reduction in the dimensions of the alveolar crest after tooth extraction. After implant placement in a fresh extraction site, a gap is often formed between the ridge and the implant surface. With a view to overcoming this issue and to favor bone formation within the gap, several grafting procedures have been employed in association or not with barrier membranes as well as several types of bone substitutes. In this context, this article aims at conducting a literature review to discuss the use of synthetic biomaterial to fill the gaps that form around implants placed in fresh sockets. Nevertheless, no biomaterial available to date provides the desirable properties. Additionally, residual bone volume must be assessed before tooth extraction in order to allow the dental surgeon to employ different techniques with a view to preserving the alveolar bone.
