TEMPORARY PLASTIC CROWNS IN PROSTHODONTIC DENTISTRY: CLINICAL AND MATERIAL ASPECTS OF MODERN PROVISIONAL RESTORATIONS

Abstract

Abstract 
  Temporary crowns are an essential component of fixed prosthodontic treatment, 
providing  protection  of  prepared  teeth,  maintenance  of  occlusal  function,  and 
preservation  of  aesthetic  appearance  during  the  interim  period  before  definitive 
prosthetic  restoration.  The  present  study  analyzes  clinical  and  material  aspects  of 
temporary  plastic  crowns,  including  their  fabrication  techniques,  biomaterial 
properties, and associated complications. Special attention is given to acrylic and bis-
acrylic  resin  systems,  as  well  as  CAD/CAM-based  provisional  materials.  Clinical 
evaluation  indicates  that  bis-acrylic  materials  demonstrate  improved  mechanical 
strength, superior marginal adaptation, and enhanced aesthetic outcomes compared to 
conventional  acrylic  resins.  Proper  fabrication  protocols  significantly  reduce  the 
incidence of complications such as gingival inflammation, crown dislodgement, and 
marginal  leakage.  The  findings  confirm  the  clinical  importance  of  high-quality 
provisional restorations in achieving long-term success in fixed prosthodontic therapy.
