Autogenous Demineralized Dentin Graft for Third Molar Socket Regeneration
The management of the osseous defects distal to the second molars as a result of the surgical removal of impacted wisdom teeth can be a challenge. The reasons for third molar extraction are varied like pericoronitis, decay, risk of damage to adjacent teeth, cyst or tumor formation, or to facilitate orthodontic treatment. The postextraction bone loss, a physiological phenomenon will take place with alveolar resorption and the subsequent formation of bone within the socket follows osteoblastic differentiation of osteoprogenitor cells. This phenomenon continues for a period of weeks. However, studies have documentedthat the bone volume following extractions decreased by 50% within 12 months,and two-thirds of this resorption took place during the first 3 months afterextraction. Bone resorption will result in a loss of socket width three-dimensionally that subsequently hamper the native alveolar ridge contour. Therefore, maintaining 3-dimensional alveolar bone volume is required for idea...
