Book excerpt: In an asymptomatic sample of adolescent orthodontic patients without any history or symptoms of TMD, CDCT was utilized in conjunction with a centric relation wax bit to assess condylar position and the effect one condylar discrepancy may have on the contralateral joint. Twenty-one patients between 11-16 years of age were divided into four groups based on degree of CPI discrepancy in the horizontal and vertical plane, and iCAT images taken with use of an anterior wax bite. Digital linear measurements were recorded similar to the method used by Ikeda for anterior (AS), superior (SS), and posterior (PS) joint spacing for all 21 patients. Joint spacing on one condyle was moderate to highly correlated with joint spacing on the contralateral condyle. There were no significant differences between condyles within the same patient in any of the 4 groups. There were no significant differences between groups except for the SS spacing between Group 3 and Group 4. Within the CPI range 0-2.5mm studied, the effect of CPI values in one or multiple joints had no statistically significant effect on joint position as measured by the CR technique described. Determination of optimal joint space must address technique for registration of bite, inclusion criteria of patients, and method of measurement. Joint spacing mean values for this adolescent orthodontic population are: AS = 2.06mm (+/- 55), SS = 2.67mm (+/7 79), PS = 1.88mm (+/- .51).
