method for estimating the maxillary basal seat for complete denture

40 edentulous maxillary casts were obtained by standard technique. The area of the basal seat was outlined and estimated using the suggested wax and graph paper method in comparison to two other usable methods [emperical equation and replication methods]. Results were analized and compared. It can be concluded that: 1. Wax and graph paper method is considered as valid method for estimating the maxillary basal seat for complete denture. 2. It can be applied to measure the area of the mandibular basal seat. 3. Evaluating the area of basal seat for cases of extensive partial dentures can be done by this method

Causes and treatment of acrylic complete denture base fractures

132 fractured acrylic upper and lower complete dentures were examined and evaluated from both technical and clinical points of view to detect the causes of fracture. After proper mouth examination and repair, dentures were examined in both oral cavity and outside. Treatment was achieved by either repair only using chloroform technique or by relining, rebasing, change of vault material and by making new dentures. Patients were examined periodically through a period of one year to detect the validity of the treatment
