Abstract
Dentin has been an important topic of study for its potential use as a bone substitute because it has a higher mineral content than any material derived from bone. Furthermore, dentin is similar to autologous bone in two ways: it is both osteocompatible and osteoconductive, thus providing a physical matrix for the sediment of new bone. In this comparative study, we evaluated the osteoinductive and osteoconductive possibilities of various materials normally used in “socket preservation” or alveolar ridge preservation. From the results obtained, it can be seen that autologous dentin matrix and bovine-derived xenografts (Bio-Oss) achieved better bone regeneration with a greater amount of newly formed bone (expressed by the BV/TV parameter) and less fibrous bone, which has unfavorable characteristics for implant biomechanics.
