Title: Clinical, radiographical and questionnaire study of failures of fixed partial dentures/ crowns fabricated in fixed prosthodontics clinic in college of dentistry, king khalid university,abha,ksa

Abstract:

Failure of  Fixed partial dentures and crowns is a very vital question to be answered. One of the hurdles for us is to identify the failure and the best way to identify the failures is by first classifying the failures and then looking out which type of failure is most common and what could be the underlying reason for the failure. Over the years many authors have put forth various methods of classifying failures of crowns and FPDs1,2 . Authors differ in their opinion of which type of failure is most common. Mechanical failures is more common than biological failures by some clinicians1 . Few studies have reported that the lowest incidence of clinical complications was associated with all-ceramic crowns followed by Posts and cores and conventional single crowns3. The 3 most common complications associated with posts and cores were post loosening , root fracture  and secondary caries4. So various studies have put forth different views on the failures of the prosthesis. This present study will bring into light the type of failures which are more common in FPDs and crowns fabricated in fixed partial denture clinic in college of dentistry ,king Khalid university,Abha,Saudi Arabia
