Evaluating the Performance and Efficiency of Zirconia Crowns in Treating Primary Teeth

Occlusal reduction by decreasing the occlusal surface to less than the natural occlusal profile by about 1-1.5 mm roughly. Proximal reduction by unfastening the interproximal contacts. The tooth should be trimmed down circumferentially by around 0.5-1.25 mm as needed. Subgingival reduction, leaving no undercuts or subgingival ridges, about 1-2 mm subgingivally on every area should be prepared. Completion of the preparation by eliminating sharp lines and pointed angles to allow all prepared areas to be marginally rounded and smoothed. Locally Made Zirconia Crowns are fixed using Glass Ionomer cement (Fuji- Jaban).
