APPLICABILITY OF MOYER'S MIXED DENTITION ANALYSIS IN INDIAN POPULATION: A REVIEW

Dr. Mohamad Arshid Khanday* and Dr. A.R Prabhakar M.D.S.,

ABSTRACT

The treatment planning in interceptive orthodontics is important to predict space required and available for unerupted canine and premolars in the arch and this determination of tooth size must be done before eruption of canine and premolars by a method called Mixed Dentition Space Analysis. The accurate prediction is very important to determine the severity of malocclusion and achieve correct orthodontic diagnosis and treatment planning. Moyers 75th percentile level prediction table is the globally used method to estimate the mesiodistal crown width of unerupted teeth; however the accuracy of this probability table has been recently questioned. Since the mixed dentition analysis is of paramount importance to precisely determine the space needed for alignment of canines and premolars, this research aimed at objectively assessing in the literature such an important step for orthodontic dignosis to test the reliability of Moyer’s method in Indian population and it was concluded that the probability of 75% was not as accurate as expected
