Patient response to variations in denture technique. Part II: five-year cephalometric evaluation.

This study was designed to determine if differences in rates of residual alveolar bone loss could be found in patients wearing dentures made by a complex technique and a standard technique. Cephalometric radiographs were made for each of 64 patients at initial placement of the dentures and for all active patients at five yearly recall visits. These radiographs were measured to determine rates of mandibular bone loss, maxillary bone loss, loss of total face height, rotation of the mandible, and migration of the denture bases over the 5-year period. At the end of the study no statistically significant differences between the two groups of patients could be found. Examination of all participants in this study revealed rates of bone loss that were very similar to those reported by other investigators.
