Comparison of Mandibular Rami Width in Patients With Prognathism and Retrognathia
Purpose
The purpose of this study was to assess the ramus thickness in skeletal Class III and Class II patients.
Methods
Forty patients were evaluated using computed tomography scanning.
Results
Compared with the Class II patients, the mandibular ramus of Class III patients was thinner. The ramus thickness in retrognathic patients was 8.84 mm and the ramus thickness in prognathic patients was 7.80 mm.
Conclusion
The ramus is thinner in patients with prognathism than in those with retrognathia.
