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 ideal esthetic
and functional restorations.
Bone grafting to augment skeletal healing has
become one of the most common surgical techniques in recent years. Despite these essential properties drawbacks involving autogenous bone grafting
include need for the second surgery, donor site morbidity and limited availability
have led to the challenging study for alternative biomaterials with osteoinductive
potential. Read more................
