Extraction: A Parameter in Bolton Ratio
Aims: To evaluate extraction as a parameter in determination of Bolton ratio in class II division 1 cases. Materials and Methods: Thirty Class II division 1 cases were selected from the records. Bolton overall ratio was calculated. Hypothetically extraction of four different combinations of premolar...

Materials and Methods: Thirty Class II division 1 cases were selected from the records. Bolton overall ratio was calculated. Hypothetically extraction of four different combinations of premolars was done.
