Aktiv komparator: Bulk-Fill Composite Group
Participants in this group will receive cuspal coverage restorations using a bulk-fill composite resin.
The material will be placed in a single increment following adhesive application according to the manufacturer's instructions.
|
This intervention involves performing cuspal coverage restorations in posterior teeth using Shofu Beautifil Bulk Fill composite resin.
The composite will be applied in a single increment following the manufacturer's adhesive and placement protocol.
Each restoration will be evaluated clinically for wear resistance, fracture incidence, and recurrent caries during the follow-up period.
