Fourteen patients were selected according to the following criteria : patients having sufficient number of natural teeth(class I and \or class IV Aramany classification)not less than five teeth, intact soft palate , sufficient mouth opening , not exposed to radiotherapy or chemotherapy. Patients were divided into two equal groups, each of seven patients: patients of group I(Comparator) received a clasp retained obturator, while patients of group II(Intervention) received an attachment-retained obturator (RCT). The design of the definitive obturator for group I included double Aker's clasp on the first , second premolars and molars with alternating buccal and lingual retention, palatal plate as a major connector and a meshwork extension at the defect side. For group II, crown preparation of all the remaining abutments was done. Then, in the wax pattern, a lingual guiding plane was prepared and two OT Vertical attachments were attached mesial to the most anterior abutment and palatal to the second premolar and first molar . Construction of the splinted crowns were completed and the final impression was made with the splinted crowns in place to be picked up into the impression. After final try-in of the obturator, construction of the definitive obturator was completed with a hard resin hollowed obturator bulb, functional relining with soft silicone liner for both groups.
