Statement of problem. Reliable measurement of individual gonial angles is difficult because of the superimposed images appearing on the lateral cephalograms. However, this disadvantage is not encountered in orthopantomography. Purpose. This study determined whether the mean measurements of the mandibular angles of a group of totally edentulous patients were greater than those of unilaterally and posteriorly partially edentulous patients. Changes in the gonial angle between denture wearers and nondenture wearers in each group were also compared. Material and methods. A total of 134 panelipse radiographs were used for measurements of mandibular angles. All radiographs used in this study were taken with the same panelipse machine by the same person. Of the 134 radiographs, 49 were of unilaterally and posteriorly partially edentulous adults and 85 were of totally edentulous adults. Results. No significant differences were found between the mandibular angles when comparing partially edentulous and totally edentulous subjects. Conclusion. Within the limits of this study, there was no significant difference between the dentulous and edentulous states. (J Prosthet Dent 1998;80:680-4.)
