KATLEEN BRAGANCA, L et al. The biology of osseointegration in postextraction implants. Av Odontoestomatol [online]. 2018, vol.34, n.3, pp.131-139. ISSN 2340-3152.

The biology of osseointegration involve a process of healing with bone resorption and bone apposition, as described histologically in animal and human studies. The removal of teeth followed by immediate implant placement results in marked alterations to alveolar ridge dimensions as well as horizontal and vertical gaps between the bone walls and the implant. Resorption of the buccal plate was seen to be more pronounced; this bone dehiscence following implant placement corroborates findings reported in animal experiments and confirmed in clinical studies with patients. Several factors affecting the biologic response of peri-implant tissues and bone-implant contact in postextraction implants as original bone density, implant surfaces, implant design and surgical technique.
