long-term evaluation of combined prosthetic-surgical approach and soft tissue augmentation in the esthetic zone

Background. there is no standard protocol for immediate implant placement and subsequent loading in the smile zone. we aimed to evaluate the long-term outcomes of simultaneous implant placement, soft tissue grafting, and immediate prosthetic loading in the esthetic zone. methods. thirty-five implants were placed in the maxillary aesthetic zone. twenty-two patients were evaluated using the pink esthetic score (pes) and white esthetic score (wes). also, the degree of peri-implant bone resorption and patient survey were applied for the esthetic and functional outcomes. results. the esthetic and harmonizing outcomes were achieved according to the mean total pes/wes value (17.9±2.0). the mean overall pes was 8.5±1.66. the papilla level had the highest mean score (1.8±0.36). furthermore, the combination of root convexity/color and soft tissue color and texture was one of the key values in evaluating the effectiveness of this method (the mean value was 1.5±0.5). the mesial and distal papillae were 1.6±0.5 and 1.8±0.4, respectively. none of the 35 implants reached below 6 points (which is considered an esthetically unsatisfactory result). the mean wes score was 9.5±0.57. the average degree of total peri-implant bone resorption was 1.05±0.3 mm after 12 months. according to the questionnaire, all the patients smiled without hesitation and were satisfied with the treatment (100%). conclusion. this study showed that restoring one or more teeth in the smile zone using the concept of one-stage implant placement, soft tissue flap augmentation, and loading with provisional crowns was an esthetically successful and predictable method.
