Design outcomes

Primary

MeasureTime frame
The study is expected to demonstrate that Polyether Ether Ketone (PEEK) crowns exhibit clinical performance comparable to preformed zirconia crowns in primary molars with respect to crown fracture, retention, and marginal adaptation. Comparable structural integrity and stability under functional conditions are anticipated. The findings may support PEEK crowns as a reliable full-coverage restorative option in pediatric dentistry.Timepoint: The study is expected to demonstrate that Polyether Ether Ketone (PEEK) crowns exhibit clinical performance comparable to preformed zirconia crowns in primary molars with respect to crown fracture, retention, and marginal adaptation.
