The aim of the present study was to\assess the effect of full contour zirconia and PMF on the retention of Acetal Resin Maxillary class I Kennedy classification is composed of two typical educational acrylic resin models, with residual teeth stretching from the right first premolar to the left first premolar teeth. Porcelain fused to metal and full zirconia crowns, proximal guiding planes, and buccal undercuts of 0.50 mm were placed on both first premolar teeth of each cast. Based on the type of crown used, the casts were split into 2 groups. Each acrylic cast was reproduced to make refractory casts. The acetal resin samples were prepared according to the manufacturer's specifications. A wax pattern tegingue was utilized to fuse porcelain to metal, and a CADCAM machine was used to create a full zirconia crown. Buccal undercuts of approximately 0.50 mm and proximal guiding planes Based on the type of crown utilized, the casts were split into two groups. To manufacture refractory castes, each acrylic cast was replicated. The acetal resin samples were prepared according to the manufacturer's specifications. Each clasp and its model were tested using universal test equipment. The clasp's retention force was tested using a universal testing machine running at 5 mm/min and recorded by computer software. With an acetal resin clasp, both types of ceramic systems have retentive forces. The amount of retention was unaffected by any form of ceramic.
