A total of 36 teeth will be randomly assigned to receive either a metal-ceramic (D'Sign) or an all-ceramic crown (IPS Empress2, Eris EXC). Randomization will be done through a random number table. Teeth will be prepared by two operators: Dr. Josephine Esquivel-Upshaw and Dr. William Rose both from the General Dentistry department. Provisional restorations will be made from Integrity (Dentsply, USA) and final impressions will be made with a polyvinylsiloxane material using the two-stage technique. Master casts will be mounted in centric relation.
