The aim of this study was to provide longitudinal evaluation of the changes
after complete dentures therapy and the rate of residual ridge resorption
through a six-year period of denture wearing. The authors presented the case
of a 76-year-old patient, edentulous for twelve years, wearing complete
dentures for six years, with the eugnat jaw relationship. Cephalometric
radiograph was carried out in the process of new complete denture production,
while the evaluation was carried out after six years. Cephalometric analysis
was performed by using ?Dr. Ceph? computer software (FYI Technologies, GA,
USA). After six years, the reduction of anterior total facial height was 5.5
mm and the anterior lower facial height was 5.5 mm, the vertical residual
ridge reduction of the maxilla was 1.4 mm and the reduction of the mandible
was 3mm. The study confirms the reliability and advantages of cephalometric
analyses and reveals their application possibilities in prosthetic
diagnostics and therapy, as well as in evaluation of rehabilitative results
in edentulous patients and longitudinal analysis of changes on the orofacial
complex tissues and intemaxillary relationships.
