The reduction in the carious disease has directed our restorative efforts toward new pathologies such as tooth wear or bio-mechanical failures of non-adhesively restored posterior teeth, related to extended periods of function and parafunctions. The bio-mechanicals implications of normal and abnormal occlusal stresses on fragilized teeth represents then a considerable clinical challenge in today’s dentistry as we strive for more conservative and durable treatment strategies.

 

Optimal restorative scenarios will then rely on proper evaluation of the residual tooth structure quality (vitality or non-vitality), pulpal status (absence of symptom absence or pain to pressure, sensitivity to cold or pulpitis), amount of hard tissues loss and presence / extent of cracks to assess which material, preparation approach and restorative technique shall be applied. Direct and indirect techniques have to be used, depending on the aforementioned criteria, with or without preparation, depending on the tooth stabilization and reinforcement needs.  

​

This program will overview diagnosis elements, decision criteria and clinical protocols related to the various, specific bio-mechanical conditions of the “cracked tooth syndrome” and non-vital teeth.
