Rules of survival (of restorations and teeth)

14:30 - 15:20

Satisfactory survival of restorations is central to patient contentment and successful practice, given that unmet expectations may lead the patient to seek the advice of a lawyer. Information on how to prolong restoration longevity is therefore of potential value to clinicians and their patients. In addition, there is a relationship between the type of restoration placed and the lifespan of the restored tooth.

This presentation will therefore explore factors which may affect restoration survival, such as choice of material, quality of the material used, plus a wide variety of tooth, patient and clinician factors. The results for survival will be taken from clinical evaluations carried out in general dental practice and the value of Kaplan Meier statistical analysis of the world’s largest dataset for restoration longevity will be explored, as this facilitates examination of the survival of, not only restorations, but also survival of the restored tooth.

Following attendance on this course, delegates should:

  • Be aware of value of choosing the correct, high-quality material for a given clinical situation
  • Be aware of the latest information on bonding to dentine and survival of resin composite materials, including bulk fill and optimum matrix systems
  • Have a modest awareness of what Kaplan Meier statistical analysis is about
  • Know the clinical situations when a crown (as opposed to a direct-placement restoration) might adversely affect the survival of the restored tooth
