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 implan...

Description
Summary: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 10% occurred at six of 25 thin biotype sites compared to two of 19 thick biotype sites. Acceptable outcomes were achieved in the majority of sites; between 10% and 20% of sites had suboptimal esthetic results. Conclusions: Immediate implant placement without elevation of surgical flaps is associated with recession of the marginal mucosa that may fall within the threshold of visually detectable change. The orofacial position of the implant shoulder and the tissue biotype are important contributory factors.
