Comparative Evaluation of Marginal Fit and Fracture Resistance of Provisional Crowns Fabricated by Conventional Method, Three-dimensional Printing, and Computer-aided Design/Computer-aided Manufacturing Technology: An In Vitro Study

IntroductIonIn today's rapidly advancing field of dentistry, where patient expectations and awareness are higher than ever, clinicians must constantly evolve their practice to provide rapid and long-lasting care. 1 In the field of prosthodontics, wherein some long-term treatments can take months or years to give final results, delivering an appropriate interim or provisional restoration is of utmost importance. 2 They should not only meet the patient's esthetic demands but should also preserve the underlying tooth structure from thermal, microbial, and chemical abuse. [1][2]][3] An incompetent provisional restoration can result in complications, such as poor esthetics, functional discrepancies, recurrent caries, and gingival irritation. [4][5]5][6][7] Sufficient fracture resistance to sustain masticatory forces and accurate marginal fit are two of the most significant properties to be taken care of while 1-
