A common axiom in conventional prosthodontics for partial edentulism is a fixed partial denture. Fewer the natural teeth missing better the indication for fixed partial denture. Unfortunately every case is different in relation to anatomical variations, patient's desires and medical condition. There is no iron clad rule for a particular design. A subtle modification in designing is required to suit a given particular case. Dentistry is an ever changing branch. Over the period of time many types of bridges have come up ranging from the traditional to resin retained to the implant retained bridges. Apart from conventional fixed partial denture modem dentistry involves implants to restore patient to normal contour, function, comfort, esthetics, speech, and health regardless of atrophy, disease or injury of stomatognathic system. With the treatment options available today, a dentist's knowledge and vigilance, adequate skilled lab support and patient's cooperation can help to achieve the only goal of a prosthodontist that is meticulous replacement with maximum preservation.

Dental implant failure has led to continuous innovations of various implants systems and to different interceptive treatment modalities. These concerns have also led to selection of implant designs that best suit the various types of bone. There are a variety of reasons for the failure of endosseous implants. Different reasons for the implant failure and their contributing factors have been discussed. The various studies done on each of these failures and how to prevent these failures have been discussed too. Failure of implants has a multifactorial dimension. Often many factors come together to cause the ultimate failure of the implant. One needs to identify the cause not just to treat the present condition but also as a learning experience for future treatments. Proper data collection, patient feedback, and accurate diagnostic tool will help point out the reason for failure. An early intervention is always possible if regular check-ups are undertaken.
