This study examined the clinical performance of the scalloped NobelPerfect implant in a one-stage procedure (immediate provisionalization in the esthetic zone). In 20 patients, immediate prosthetic restorations were placed on 31 NobelPerfect implants and followed for up to 27 months. Outcome variables were success rates, marginal bone levels, and Pink Esthetic Score (PES) assessed per implant. One implant failed (success rate: 96.8%). Marginal bone levels averaged 1.7 mm above the first thread and remained stable during the observation period. Mean PES ratings were 11.3 (range, 8 to 14). Survival rates, marginal bone levels, and esthetic results suggest proof of principle for the preservation of the interproximal bony lamella with a scalloped implant design. [ABSTRACT FROM AUTHOR]
