Abstract:Purpose: This study aimed to evaluate the impact of various preparation designs on marginal adaption of pressable ceramic crowns.
Materials and Methods:Forty freshly extracted maxillary premolars were used. Premolars were prepared to receive crowns with two marginal designs. The samples were divided randomly into two equal groups based on the tested ceramic materials (n=20); Group E for IPS e-max press and Group C for Celtra press. Each group was subdivided into two subgroups according to the tested finish lin… Show more
