Evaluation of zirconia and titanium abutments on peri-implant tissues: A comparative study.

The comparative effect of zirconia and titanium abutments on peri-implant hard and soft tissues is of interest to dentists. Hence, a total of 40 patients with single-tooth implants in the posterior region were selected and divided into two groups: zirconia abutments (Group A, n=20) and titanium abutments (Group B, n=20). Clinical parameters, including probing depth (PD), bleeding on probing (BOP) and peri-implant marginal bone level (MBL), were evaluated at baseline, 3 months and 6 months post-implant placement. Radiographic analysis was used to measure changes in marginal bone levels. Zirconia abutments showed a more favourable outcome on peri-implant soft tissue health and marginal bone preservation than titanium abutments. Zirconia abutments further show reduced inflammation and bone resorption around dental implants.
