Immediate Implant Placement Postextraction Without Flap Elevation

Background: The aim of this retrospective study was to assess soft tissue and esthetic outcomes at single-tooth immediate implants placed without flap elevation in maxillary central and lateral incisor sites.Methods: Photographic records of 85 consecutive patients with immediate single-tooth implants in maxillary central and lateral incisors that were placed without elevation of surgical flaps were selected. The change in mucosal level was expressed as a percentage of the length of the reference central incisor.Results: Significant recession of the mesial papilla (−6.2% ± 6.8%), distal papilla (−7.4% ± 7.5%), and facial mucosa (−4.6% ± 6.6%) between surgical placement and 1 year was observed (P <0.001). Recession was greater for implants placed facially within the extraction socket compared to those placed lingually (P = 0.009). Sites with gingival margins initially coronal achieved mucosal levels close to the line of symmetry with the contralateral tooth. Sites initially level or apical failed to reach t...
