There were only a few studies investigating the effect of sagittal root position (SRP), sagittal root angle (SRA), and buccal bone thickness (BBT) on peri-implant tissues using the socket shield technique (SST). This retrospective case series aimed to evaluate the SRP, SRA, and BBT in socket shield cases and examine the effect of these anatomical factors on the peri-implant tissue phenotype and bone level. Data from 27 patients (14 women, 13 men) treated with SST in the maxillary esthetic region between July 2019 and September 2021 were included. Clinical indices (modified plaque and bleeding indices, probing depth, keratinized mucosa width, mucosal thickness) and periapical radiographic recordings (marginal bone level) taken immediately after permanent prosthesis placement and 1 year later were used. Cone beam computerized tomography images were used to examine BBT, SRP, and SRA before implant placement and horizontal and vertical bone levels before implant placement and 1 year after prosthetic rehabilitation. The data were divided into groups based on BBT (<1 and ≥1 mm) and SRA values (<10° and ≥10°). There were no significant differences in 1-year clinical factors between the SRA <10° and SRA ≥10° groups. However, higher vertical bone loss was found in the SRA ≥10° group (P =.01, d = 0.53). There were no significant differences in clinical or radiographic factors between the BBT <1 mm and BBT ≥1 mm groups. In conclusion, BBT showed no significant effect on tissue phenotype and bone level, but SRA affected bone level in socket shield cases. [ABSTRACT FROM AUTHOR] |
