Evaluation of functional impression techniques for mandibular bilateral distal extension cases

ABSTRACT

This study was conducted to compare two functional impression techniques with the mucostatic one in construction of mandibular class I kennedy classification. Six partially edentulous patients were selected and prepared for construction of cobaltchromium removable partial denture against complete denture. For each patient, mucostatic impression was made and the resulted cast compared with two casts poured from functional impression techniques; the frist was a static function impression material and the other was dynamic functional relining impression using korecta Wax IV. The two functional casts were made by altering the mucostatic one and compared with it as regard the degree of compression produced by each functional impression technique to the mobile compressible tissues over the ridge
