Enxertos ósseos autógenos de áreas doadoras intra-orais: revisão de literatura

Abstract

The success of dental implant therapy is closely related to the remaining bony tissue quantity which is not ever found. Therefore, alveolar bridge augmentation and maxillary sinus lift techniques have been developed in order to make possible the viability of the implant uses. For the bridge augmentation techniques, there is a consensus for the use of intra-oral autogenously bone in small flaws or extra-oral bone from autogenously iliac crest, which is used when there is the necessity sinus lift, several materials are used, being the aloplast graft (tricalcium phosphate, hidroxyapatite), allogenies (desmineralized freeze-dried bone), xenogenies (deprotenized bovine bone mineral) and autogenous bone, the most common ones. There is no consensus for the use of such materials with high success rate for all; just in case when the remaing bone makes itself essential. Moreover, allogenic grafts are rather very slowly reabsorbed and make up bone of low quality as well.
