Initial Bone Bed Activation: Bone Matrix Osseotensors—Tissue Engineering

摘要: Osseointegration of dental implants requires sufficient intrabony blood supply. In extremely resorbed areas, however, the main source is periosteal arteries. Basal implant placement in severely atrophic jaws thus especially challenging because poor quality as well reduced volume future recipient bone site. This situation aggravated smokers. Calvaria or iliac grafts, mental nerve displacement, and sinus lift procedures are often performed prior to overcome initially unfavorable biological, anatomical, mechanical status. Patients reluctant undergo such procedures, though, they time-consuming expensive involve unpredictable degrees morbidity at donor and/or sites. Although free grafts (autologous substitutes) can augment volume, do not promote better supply per se; only vascularized pedicular capable this. Furthermore, some instances, postsurgical scar tissue actually reduces Stem cell activation using osseotensors use PRF membranes two approaches developed these difficulties.
