Clinical application of a maximum intercuspal position-centric relation occlusion conversion of a lateral cephalogram in the treatment of orthodontic patients

Abstract

• Evaluation of the condylar position is important in the diagnosis and treatment of orthodontic patients, and centric relation occlusion (CRO) should be the starting point of mandibular movement and orthodontic diagnosis. • The condylar position information obtained from an articulator in CRO can be transferred to a lateral cephalogram taken in maximum intercuspal position (MIP) using a MIP-CRO conversion technique. • The results of the MIP-CRO conversion provide a more accurate and predictable orthodontic treatment plan. Evaluation of condylar position is a critical step in orthodontic diagnosis. Diagnosis using an articulator-mounted model helps orthodontists establish an orthodontic treatment plan on the basis of centric relation occlusion (CRO). The quantitated condylar position obtained from an articulator can be transferred to a lateral cephalogram taken in maximum intercuspal position (MIP) using a MIP-CRO conversion technique. This article details the step-by-step procedure with comprehensive illustrations for applying MIP-CRO conversion for diagnosis. The results of the MIP-CRO conversion provide a more accurate and predictable orthodontic treatment plan.
