Evaluation of the Effect of the Biodegradable Membrane on the Outcome of Immediate Implant Placement in the Esthetic Zone

Dental implant was placed to restore the function of the teeth as well as satisfactory appearance. A great challenge with implant placement and tooth restoration in the aesthetic zone has been presented as a common issue in tooth replacement. The ability of the dental team to re establish normal form and architecture to hard and soft tissue has been concerned [1]. Originally, it was considered that complete healing of extraction socket had occurred before implant placement as a prerequisite for osseointegration that is called delayed implant. Later it has been shown that combination of extraction and implant placement can successfully be performed as a one-stage operation [2,3]. This combination of demands could complicates the task of the surgeon while a reduced treatment period can be accomplished by immediate placement of the implant. However it makes the patients more satisfied especially from the esthetic point of view [4]. The soft-tissue surgery involved in the procedure often produces a compromised aesthetic results these were presented as (broken mucogingival border, the adjacent papillae are destroyed and sometimes results in a buccal concavity, mucosal perforation, disintegration of the implant subsequently long healing period of both hard and soft tissue) [5]. Achieving an esthetically pleasing restoration involves not only harmonizing the size, shape, position and color of each prosthetic tooth with the adjacent teeth; but establishing a stable peri-implant tissues compatibility with the surrounding gingiva and mucosa is also essential. So the aim of this study to avoid this by placement of biodegradable membrane that cover the implant and guide the soft tissue for healing progression.
