Figure 22. Day 1: Blood coagulation and inflammatory cells Hard and soft tissue composition in the extraction socket during longer healing periods was documented in a study by Cardaropoli and coworkers, in which the entire healing cascade after tooth extraction was evaluated in a dog model. The following images are histologic specimens representing the stages of healing observed in their stud...

Figure 21. Histologic sequence of healing The healing of an extraction socket is characterized by a sequence of histologic events taking place in four distinct stages: inflammation, fibroplasia, mineralization, and remodeling. This cascade of events in the extraction socket is similar to intramembranous bone formation in other types of osseous defects and begins with the inflammation stage. D...
