This study was conducted on sixteen patients with unilateral mandibular distal extension area with second premolar is the last abutment teeth. This study aimed to evaluate patient satisfaction and biting force of patients with unilateral mandibular distal extension area treated with two different design of removable partial denture. The patients were divided into two equal groups, group I received conventional removable partial denture which provides cross arch stabilization and a double aker clasp was fabricated.Group II received new design of extracoronal castable precision attachment (OT Unilateral attachment). Patients of both groups were evaluated at the time of prosthesis insertion, three, six and twelve months later. Evaluation included patient satisfaction by and biting force by load star sensor. Results at the end of follow up period showed statistically significant increase in group II (OT unilateral design) in patient satisfaction and biting force and it was more comfortable and satisfactory tolerated by patients than conventional partial denture. From the results of this study, it was concluded that: It's preferable to use the new design of extracoronal castable precision attachment (OT UNILATERAL) being simpler, more comfortable to the patients and give high masticatory efficiency in the form of biting force than conventional removable partial denture
