Figure 46. Dimensional ridge alterations in 1 week Araujo and Lindhe described the edentulous ridge profile alterations following tooth extraction in an experimental study in a dog model. During the first week of post-extraction healing, the socket area is occupied by coagulum and granulation tissue. A large number of osteoclasts are seen on the outer as well as on the inner s...

Figure 33. Day 3: granulation tissue & inflammatory cells After 3 days, small segments of the coagulum at the margins of the socket are replaced by a highly vascularized granulation tissue with an inflammatory cell infiltrate.

Figure 30. Quantitative tissue analysis Trombelli and coworkers monitored the healing of human extraction sockets for a 6-month period and presented a semi-quantitative analysis of tissues and cell populations involved in various stages of socket healing. They showed that granulation tissue was present in comparatively large amounts in the early phases of socket healing. At 6 to 8 weeks, th...
