A Pilot Study On Clinical Performance Of Resin-bonded Ceramic Restorations

Objective:To evaluate the clinical performance of resin-bonded lithium disilicate glass ceramic restorations in treatments of severe tooth wear,dental fluorosis,and diastemata.Materials and methods:Fifty-four teeth(40 anterior teeth,14 posterior teeth)of nine adults(2 men,7 women)affected by severe tooth wear,dental fluorosis,or diastemata were restored with resin-bonded ceramic restorations between October 2014 to January 2019 at the Stomatology Hospital affiliated to Zhejiang University School of Medicine.All restorations were fabricated with lithium disilicate ceramics and boned to teeth using light/dual cure resin cements.Clinical performance of all the restorations was evaluated by the modified United States Public Health Service criteria.Results:After up to 56 months clinical observation(mean observation time 17 months),survival rate of the restorations was 100%.According to the modified USPHS criteria,all criteria achieved 100%alfa rate except for marginal adaptation(18.5%bravo rate)and color match(3.7%bravo rate).Conclusions:The short-term clinical performance of resin-bonded lithium disilicate glass ceramic restorations for severe tooth wear,dental fluorosis and diastemata could achieve the excellent results.
