Comparative study of Interim Materials and CAD/CAM systems: a Literature of Review

Prosthodontic treatment sometimes requires a long-term interim fixed dental prosthesis (FDP) until the definitive restoration can be cemented. However, some interim materials are weak and do not have an adequate marginal seal. The CAD/CAM systems have developed considerably, offering accuracy and more options than previously. It can be envisioned that CAD/CAM technology developments will continue to offer dentistry more options for its use, including further CAD/CAM integration of procedures and imaging enhancements. With the advent of new interim crown materials, it has become imperative to evaluate its strength in order to select the appropriate interim crown and partial fixed dental prosthesis material. However, there is lack of information on marginal gap and fir of interim materials using CAD/CAM systems. So, this review paper studied the comparative study of interim materials and CAD/CAM systems using the PubMed and Medline database for recent history. The aim of this literature review was to provide useful information prosthodontics.
