Immediate Placement and Restoration of Dental Implants in the Esthetic Region: Clinical Case Series
MetadataShow full item record
Aim The objective of this study was to assess the hard and soft tissue changes following immediate placement and provisional restoration of single-tooth implants in the aesthetic zone. Methods Thirteen patients with immediately placed and restored implants were included in this study. All participating patients underwent the same treatment strategy that involved removal of the failed tooth, flapless surgery, immediate implant placement, and connection of a screw-retained provisional restoration. Three months following implant placement, the temporary crowns were replaced by the definitive restorations. Implant survival rates, and hard and soft tissue changes were measured using periapical X-rays and photographs. The range of the observation period was between 12 and 37 months with a mean period of 23.2? .6 months. Results At the time of follow-up, all implants were present with no complications. Radiographic evaluation revealed a mean mesial bone gain of 1.20?.01?mm and a mean distal bone gain of 0.80?.14?mm, which reached statistical significance. The mean mid-buccal recession was 0.20?.78?mm, whereas the mesial and distal papillae height loss was 0.50?.26?mm and 0.30?.82?mm, respectively. The changes in the soft tissues did not reach statistical significance. Conclusion Notwithstanding the limitation of a small sample size, this study shows that immediate implant placement and provisional restoration in the maxillary aesthetic zone can result in favorable treatment outcomes with regards to soft and hard tissues changes over a follow-up period of 23.2? .6 months. Clinical Significance Most clinical trials investigating immediate implant placement and immediate restoration in the maxillary anterior zone have focused on implant survival and implant success, with particular emphasis on radiographically assessed hard tissues changes. However, this study assesses the soft tissue changes associated with this procedure, which is an important area of study given the esthetic demands of implant therapy in the maxillary anterior region.
