Immediate Loaded Implants Placed in Fresh Extraction Sockets - Effect on Marginal Bone
Sammanfattning: This study investigated the immediate implant placement in the maxillary aesthetic zone without flap elevation or enhancement of the hard tissue component with filler or membrane material. The aim of this paper is to study treatment outcome for immediate implant placement in fresh extraction socket in the maxillary anterior region regarding marginal bone level. This retrospective cross-sectional study includes data on 41 patients, total of 54 implants (n = 54), treated for immediate placed implants without flap elevation. 30 patients, a total of 33 single immediate implants were placed in the anterior maxilla and immediately restored with a temporary crown. In another 11 patients, 21 implants were placed in fresh extraction sockets and temporalized with a provisional bridge engaging immediate implants and in some cases in combination with delayed implants. No implants were lost during the follow-up period, mean radiographic follow up was 32 months. Analysis of the radiographs presented mean bone level of all sites 1.47 mm (SD 1.63) immediately after the installation and 0.85 mm (SD 0.75) at the follow up evaluation, resulting in a mean bone gain of 0.62 mm. With careful patient selection immediate placement of implant in fresh extraction socket can be an attractive treatment modality in maxilla anterior region.
