title: [Evaluation of the masticatory efficiency of linear occlusal dentures].
abstract: OBJECTIVE
  To study how the linear occlusal dentures perform the function with the most restricted occlusal contact areas.
  
  
  METHODS
  A study of masticatory efficiency was made for 33 patients wearing linear occlusal dentures compared with that of 30 patients wearing anatomic occlusal dentures.
  
  
  RESULTS
  There is no difference between the linear occlusal dentures group and the controlled group when tested by fixing mastication time, while 81.8% of the experimental group with severe RRR, and the controlled group being only 43.3%.
  
  
  CONCLUSIONS
  Linear occlusal dentures work well for edentulous patients, especially for the cases with flat or depressed residual ridges.
