title: Preparation of abutment teeth with a specialized clinical parallelometer.
abstract: OBJECTIVE
  A compulsory requirement for the treatment of defects in the dentition is to establish parallelism in the abutment constructions.
  
  
  METHODS
  We propose a simplified effective parallelometer that is fixed to the handle of a metal impression tray for both of the jaws. It ensures the same direction of the preparation instruments for all preparation zones. We applied the device for control in clinical practice for preparation of parallel surfaces and profiles. The working models were subjected to comparative analysis with a laboratory parallelometer.
  
  
  CONCLUSIONS
  The results obtained confirm the achieved parallelism between homonymous dental walls. There isn't an index for statistical analysis.
  
  
  CONCLUSIONS
  The results achieved allow us to recommend the device for practical application. By using the clinical parallelometer the mistakes in the preparation of bridge abutments will be reduced to a minimum.
