Gingival Recession, Localized Clinical Trial
Official title:
Gingival Response and Marginal Adaptation of Zirconia Crowns With Two Subgingival Margin Designs: A Randomized Clinical Trial
The aim of the study is to evaluate the effect of feather edge finish line and deep chamfer finish line on gingival position, bleeding on probing and marginal adaptation.
The aim of the study is to evaluate the effect of feather edge finish line and deep chamfer finish line on gingival position, bleeding on probing and marginal adaptation. Gingival bleeding on probing will be evaluated before treatment. Preparation for all ceramic full coverage restoration will be performed according to manufacturer instructions by one operator. Type of finish line (whether feather edge or deep chamfer finish line) will be selected randomly according to a computer generated randomization list. Restorative margins will be placed subgingivally. Zirconia crowns will be fabricated for the prepared teeth and cemented using resin luting agent. At 6 months and 12 months after the cementation, restorative margin position relative to the gingival margin will be recorded. Bleeding on probing and marginal adaptation will also be recorded. ;
