摘要: Abstract The amount and direction of condylar growth, glenoid fossa displacement, “effective” temporomandibular joint (TMJ) changes (a summation position within the fossa) were analyzed in 35 Class II, Division 1 malocclusions (23 boys 12 girls) treated with Herbst appliance. Lateral head films habitual occlusion mouth wide open from before (T1) after 7.5 months treatment (T2) as well (T3) three years (T4) evaluated. As a control group, sample untreated male was used during 7.5-month time period corresponding to (T2-T1) cases. results revealed that growth directed posteriorly about twice subjects, displaced an anterior inferior direction. effective TMJ showed patte...
