SUMMARY:

The esthetics and stability of the soft tissue and bone around the implant is a critical component to the long-term success of the implant and can be influenced by factors such as the type of prosthetic connections. OBJECTIVE: To compare the behavior of the peri-implant tissue of single implant-supported crowns in the anterior aesthetic area using prefabricated titanium prosthetic abutments (G1) and customized zirconia prosthetic abutments (G2). METHODOLOGY: In this controlled, blinded, non-randomized clinical trial, 30 single cemented anterior implants were sequentially allocated: 15 implants rehabilitated on implant system with a prefabricated titanium prosthetic abutment (G1) and 15 on implant system with customized zirconia prosthetic abutment (G2). The behavior of the peri-implant tissue was evaluated at T0 (beginning of tissue conditioning), T1 (end of tissue conditioning), T2 (7 days after final cementation), T3 (6 months after final cementation). Visible Plaque Index (VPI), Gingival Bleeding Index (GBI), Bleeding on Probing (BoP), Probing Depth (PD), Interdental Papilla Height/Width Ratio (PH/PW), Keratinized Mucosa Width (KM), Gingival Thickness (PT), Periodontal Phenotype (PF), Gingival Recession (GR), radiographic distance from the bone crest to the contact point and Pink Esthetic Score (PES) were registered. The results were analyzed with the following statistical tests: Friedman, Mann-Whitney and Chi-square/Fisher's Exact test with a significance level of 5%. RESULTS: No statistically significant differences were observed between groups for any of the clinical parameters in any, (p>0.05). However, intragroup analysis showed a statistical reduction in VPI between T1 and T2 only for G2 (p<0.05). There was a significant decrease between T0 and T3 for GT (1.67 mm - 1.47 mm in G1, and 1.70 mm -1.47 mm in G2) and increase in the ratio PH/PW (0.56 - 0.80 in G1 and 0.70-0.83 in G2) in both groups (p<0.0001). PES also increased significantly for both groups (9 – 12 in G1 and 7 – 12 in G2) from T0 to T1 and remained high in the other periods. CONCLUSION: The results showed that the prosthetic abutments used did not impact differences in clinical and aesthetic variables related to the behavior of peri-implant tissues during the study. Therefore, the decision to select components an aesthetic area should be based on aspects such as cost, workflow and timing.
