Clinical implications and indicators of growth1/ dental implant courses by Indian dental academy

Timing of Cervical H.G treatment Kopecky & Fishman (1993 AJO Aug) performed a study to determine a skeletal maturation period when maxillary cervical head gear can be optimally used for Orthopedic movement.

They assigned each record to the maturational stage of Fishman.

They conclude that, 1) Greatest skeletal correction is obtained during the periods of greatest growth velocity between the matruational stages SMI 4-7.

2) If maximal skeletal retraction is the objective, treatment can be initiated during the stages of SMI 1-3 & continued during SMI 4-7. www.indiandentalacademy.com
