title: Comparison of anchorage loss following initial leveling and aligning using ROTH and MBT Prescription - A clinical prospective study.
abstract: BACKGROUND
  To evaluate the amount and percentage of anchor loss after initial leveling and aligning using a ROTH and MBT prescription.
  
  
  METHODS
  Pre and post alignment lateral cephalograms & dental casts of 10 ROTH & 10 MBT patients.
  
  
  RESULTS
  In the study, it was found that the amount of anchor loss is greater in the ROTH group than the MBT group. This could be due to the increased anterior tip in the ROTH prescription, compared to MBT. The total anterior tip in ROTH is 270 and in MBT is 200. The additional tip of 70 in ROTH prescription itself would have resulted in forward thrust of the anteriors.
  
  
  CONCLUSIONS
  The use of laceback and cinchbacks creates a statistically and clinically significant increase in the anchorage loss specifically when the posterior anchorage is not enhanced. In this study TPA was not used but studies have shown that passive TPA has almost no effect on the clinician's need to preserve anchorage in the correction of malocclusion. On the other hand, the TPA is an excellent way to prevent molar rotation and maintain the original vertical and transverse dimension when desired.
