Keywords:overdenture, Locator attachment, OLS attachment, CBCT, Digital occlusal analysis
This study was conducted to evaluate the effect of weight of the obturators on the supporting structures of acquired maxillary defects. Twelve maxillectomy patients class I Aramany classification were selected and were divided into two equal groups, six patients each. Hollowed maxillary obturators were constructed for each patient with same design. group I from titanium and group II from cobalt chromium. The acrylic resin used in both groups was visible light polymerized resin. Bone height and density of the supporting abutments were evaluated using the Digora com- puterized system the results showed that there was no significant difference between the two groups after six months regarding bone height and density, however. there was a highly significant difference after
