Cephalometric Evaluation of Crib Therapy for Cases of Mixed Dentition (Open Bite)
The Dental Journal of Nihon University
The effect of crib therapy for the treatment of cases of open bite was investigated. Extrusion of the lower and upper incisors and intrusion of the lower first molars were the most significant effects of the appliance. Intrusion of the lower molars resulted in decreased lower facial height. These findings were considered to result from the posterior tongue posture. Thus, the clockwise pattern of the mandibular complex was changed to a counter-clockwise pattern.doi:10.2334/josnusd1959.34.131 fatcat:tnycooobrnf7xlcpsempikutqm
