Hard and soft tissue reduction after tooth loss leads to problems when it comes to rehabilitation of the edentulous region. The main dilemma is that the residual bone dimensions are insufficient for implant placement both aesthetically and functionally.
Many methods have been introduced through the past years in order to prevent and/or reduce alveolar ridge resorption for optimal implant therapy.
This paper is a review of the literature available on tissue preservation methods with focus on the anterior maxillary aesthetic sites. The studied preservation methods were immediate implant placement with or without simultaneous grafting (depending on the presence or absence of defects/gaps), different tissue reconstruction prior to implant placements after socket healing and only extraction and then implant placement after normal socket healing.
PubMed was used as database to search for clinical articles. A total of 20 clinical articles were processed. Values from different comparable parameters of these 20 articles were obtained from different methods including the switching platform method.
This review shows that tissue preservation can be achieved by different methods after tooth loss which may facilitate optimal implant therapy depending on the method and/or material. It was concluded that all socket preservation methods gave better tissue preservation outcome than the extraction only method in the anterior maxillary aesthetic sites with more focus on the vertical and horizontal bone dimensions.
