Resumo: |
The sinus lift procedure has been used over the years as a technique with high predictability, becoming possible the implants placement in the maxillary posterior region. The alloplastics materials even though have neither osteogenic nor osteoinductor potential, have been used during a long time to replace the use of the autogenous bone grafts, showing, through its osteoconductive properties, favorable results to this kind of procedure. The hydroxyapatite commercially known as OsteoGen® is a synthetic, resorbable and nonceramic type of hydroxyapatite. It is a material produced through a low temperature process being highly hydrophilic. The literature shows that this hydroxyapatite has been used in sinus lift procedures since 1989 and recently, a new generation of regenerative materials obtained through this hydroxyapatite (Osteogen®) has been studied. The aim of this research was to review the OsteoGen® literature and to evaluate the clinical, radiographic and histological response of this resorbable hydroxyapatite used as graft material in the maxillary sinus being used in the following versions: OsteoGen® Putty (OsteoGen® in a dense consystence) and OsteoXcel® ( OsteoGen® with the incorporation of DFDBA). The results obtained using these materials showed radiographic and tomographic evidence of the maxillary sinus fulfil, allowing the implants placement followed by the prosthetic rehabilitation. The microscopic results confirmed the biocompatibility and osteoconductive properties of the material through the new bone formation observed around the remaining hydroxyapatite crystals. |
