Study Models

 

Assessment with study models alone (when there is no patient and no clinical information)

  • Assume the worst scenario
  • Overjet 3.5mm to 6mm - Assume the lips are incompetent-so award a grade 3a
  • Crossbites - Assume a discrepancy of greater than 2mm between Retruded contact position and Intercuspal position and award grade 4c
  • Reverse overjets - Assume speech and chewing problems
