The preparation of teeth for fixed prosthetic restoration needs the temporary restoration for various reasons.Once the enamel has been removed,a vital tooth of the sensitive dentin is exposed to the oral environment. If left unprotected teeth,the patient would experience a significant amount of sensitivity to the various stimulations to which the tooth is exposed.In addition,exposed dentin is much more susceptible to caries than enamel is.The prepared tooth is also lacking contact mesiodistall as well as occlusally with its counterparts in the dentition.It is not uncommon for the prepared tooth to drift mesially or distally or to extrued in an occlusal direction.This movement would,of course,cause problems in seating the final restoration.Temporization also allows for the testing of both the esthetic and functional design of the final restoration.The paper showed some fabrication methods for temporary crown and bridge and discussed the effect on the temporary crown and bridge and its needs for design.
