SUMMARY:

The stability and aesthetics of peri-implant tissues are crucial for the long-term success of dental implants in the anterior region. The choice of prosthetic abutment can directly influence these outcomes over time. In this context, the present study compares peri-implant tissue behavior by evaluating clinical parameters between prefabricated and customized abutments.OBJECTIVE: To evaluate the behavior of peri-implant tissues in esthetic rehabilitations with cemented implant-supported crowns using prefabricated titanium abutments (GT) and customized zirconia abutments (GZ) after 3 months, 6 months, 1 year, and 2 years. METHODS: This longitudinal, controlled, blind, and non-randomized clinical trial evaluated 30 cemented single-unit crowns on implants in the anterior region. The cases were sequentially distributed: 15 rehabilitated with prefabricated titanium abutments (GT) and 15 with customized zirconia abutments (GZ). Peri-implant tissue behavior was assessed at five time points: T0 (at crown installation), T1 (3 months after final cementation), T2 (6 months), T3 (1 year), and T4 (2 years after final cementation). The following clinical parameters were analyzed: Visible Plaque Index (VPI), Gingival Bleeding Index (GBI), Probing Depth (PD), and Bleeding on Probing (BOP). Statistical analysis was performed using SPANOVA – Split-plot ANOVA design with Sidak post-hoc tests, considering a significance level of 5% (p<0.05).
RESULTS: SPANOVA showed a time effect for VPI and PD (p<0.05). Between-group analysis revealed statistically significant differences for PD at crown installation and at 3 months (T1). In the within-group analysis, no significant differences were observed.
CONCLUSION: The type of prosthetic abutment used did not result in significant differences in clinical variables related to peri-implant tissue behavior over time. Higher PD values were observed at crown installation (T0) and at 3 months (T1), possibly associated with the provisional prosthetic component used. Therefore, the choice of prosthetic components for esthetic zone rehabilitation may be guided by each clinician’s individual criteria.
