Abstract

Dental implants represent a treatment option with high success and survival predictability. The great results usually are related to bone crest stability and peri-implant supporting tissues health. The material used to produce the prosthetic connector seems to play an important role on the long term of implant clinical outcome. The objective of this study was to evaluate longitudinal clinical parameters of peri-implant tissues in patients rehabilitated with unitary prostheses cemented on titanium or zirconia connectors. Were selected twenty participants rehabilitated with dental implants and cemented crowns on zirconia connectors (n = 10, anterior maxilla) or titanium connectors (n = 10, posterior maxilla/ mandible). The clinical parameters: probing depth, connective tissue attachment level, gingival recession, bleeding on probing and marginal bone resorption, were collected in the periods of masticatory function: T0 = baseline (prosthesis installation), T1 = 12 months, T2 = 24 months and T3 = 36 months. No clinical complication was observed in both connectors, with a 100% success rate. The evaluated materials and the investigated periods had a significant relative effect on the clinical parameters evaluated (p < 0.05). There was no significant difference on the total marginal bone resorption between the two materials, after 36 months. The results suggests maintenance of peri-implant health over time, in both groups (AU)
