Preservação da crista alveolar e sua importância estética na implantodontia

Abstract

The purpose of this paper was review all the scientific evidence regarding the therapeutic interventions for socket preservation after tooth extraction and to assess the potential benefit of such techniques and biomaterials disposable and its impact on dental implants therapy and esthetics. On this way, a search was performed on data basis: MEDLINE-Pubmed, BIREME, COCHRANE using the following key words: esthetics, buccal bone, bundle bone, dental implants, bridge preservation. Preliminarily a total of 88 studies were selected and after summary evaluation, 45 were included on this review. The mainly conclusions found were that alveolar ridge preservation cannot avoid totally the resorption of the socket after tooth extraction but dimensional changes should be minimized by some ARP techniques; immediate implants seems do not modify the magnitude of alveolar bone shrinkage; correct 3D positioning of the implants always guided by the prosthesis is a essential factor for soft and hard tissues preservation as well aesthetical outcomes.
