This article aims to evaluate the effect of anatomically designed, single-unit provisional restorations on soft tissue preservation following immediate implant placement. Patients in need of a single-tooth replacement in the esthetic area were recruited for this study. An immediate provisional restoration with a transmucosal area anatomically designed to support the soft tissue was used for every patient. The horizontal volumetric tissue changes and the presence and amount of vertical recession were measured at baseline (T0) and after 1 month (T1), 3 months (T2), and 6 months (T3). Sixty-three patients received 66 implants that were placed into fresh extraction sites. The average follow-up time was 48 months (range: 24 to 60 months). All implant restorations were successful, and the cumulative implant survival rate and success of restorations was 100%. After 6 months, the mean horizontal ridge measured midbuccally had increased by 0.10 ± 0.10 mm at 1 mm from the free gingival margin, had decreased by 0.09 ± 0.10 mm at 3 mm, and had decreased by 0.20 ± 0.10 mm at 5 mm. In addition, the mean recession at the midbuccal surfaces was 0.04 ± 0.37 mm. Measurements were made clinically and compared to measurements made on the casts. According to the results of this study, the use of customized anatomically designed immediate provisional restorations following single-tooth extraction and immediate implant placement appeared to minimize the loss of tissue volume that results from postextraction bone remodeling, thus optimizing the final esthetic result.

The purpose of this case series was to evaluate the survival rate and the incidence of complications of implants inserted and immediately loaded in sites where an impacted tooth was present in the anterior maxillary or mandibular arches (incisor to premolar). The implants were immediately inserted, drilling through the impacted teeth. Site preparation started in the crestal bone and continued into the impacted tooth's enamel and dentin. Seven patients were treated and 11 implants were inserted, 3 in the mandibular arch and 8 in the maxillary arch. All implants healed uneventfully without any adverse clinical or radiographic signs or symptoms, resulting in a success rate of 100%. Once loaded, the implants were in function and monitored for 5 to 7 years. Although more studies and a larger sample size are needed to validate this unconventional procedure, it may be considered as a possible clinical option to overcome invasive procedures and surgical complications related to the extraction of impacted teeth.
