For edentulous patients with unstable mandibular movements and abnormal facial features due to condylar fractures and morphological abnormalities, it is important to find a stable mandibular position. In this case, the patient’s facial improvement, mandibular movement stability, and denture stability were improved by using flat table treatment dentures. In addition, computer-aided design/manufacturing (CAD-CAM) technology was used in denture fabrication to maintain the vertical dimension and lip support of flat table treatment dentures, we report good results in improving the patient’s discomfort.

Objective: Familial cancer appears at a young age and its incidence is increasing. About 12% of familial ovarian cancer cases are associated with BRCA1/2 mutations (BRCAm). In this study, we investigated BRCA1 methylation may predict ovarian cancer in those with a family history of cancer (FHC) but without BRCA1/2 mutations (BRCAwt). Methods: Using peripheral blood DNA from 55 subjects without a history of cancer [cancer(−)] and 52 ovarian cancer patients, we examined BRCA1 promoter methylation through bisulfite sequencing of the promoter and expressed the results as the cumulative methylation index. Then, we evaluated the BRCA1 promoter methylation according to BRCA1/2 germline mutations. Results: BRCA1 methylation was more prevalent in the BRCAm cancer(−) group than in the BRCAwt cancer(−) group and ovarian cancer patients (p=0.031 and p=0.019, respectively). In the BRCAwt cancer(−) group, BRCA1 methylation was more prevalent in those with an FHC than in those without one and in the BRCAm cancer(−) group with an FHC (p=0.001 and p<0.001, respectively). Conclusion Our data suggest a predictive role of BRCA1 methylation profile for ovarian cancer in those without a history of cancer but with an FHC. BRCA1 methylation has important implications for diagnostic and predictive testing of those with BRCAwt cancer(−) status with FHC.
