Custom-made Versus Prefabricated Zirconia Crowns for Primary Molars.

Background: Do construction methods of pediatric zirconia crowns affect the periodontal health and clinical performance of badly decayed primary molars? The question asked by many practitioners. Purpose: to compare the periodontal health and clinical performance of primary molars restored with custom-made and prefabricated zirconia crowns. Hypothesis is the performance of primary molars restored with custom-made zirconia crowns will be equivalent to those restored with prefabricated zirconia crowns.
