Summary

The purpose of this study will be to evaluate the effect of direct and indirect pick up of the locator retentive caps and compare the clinical results with those of the manufacturer retentive force.

Detailed description

Patient selection: For this study, 30 patients were selected from the clinic of Prosthodontic Department, Faculty of Dentistry, Mansoura University. According to pick up technique for the locator retentive caps, the overdentures will be classified into two groups as follows; Group1: The retentive caps will be picked up by indirect method on the cast then by the direct method Group2: The retentive caps will be picked up in the patient by the direct method first then by the indirect method. For both groups, the clinical retention will be measured after using pink and blue retentive inserts respectively. All implants were inserted using computer-guided implant surgery and conventional loading protocol was used. Evaluation methods The clinical retention of each insert will be calibrated as regards the manufacturer's value. Also, the laboratory retention will be assessed for the two groups and calibrated as regards the manufacturer's value. Measurements will be done immediately, three and six months after each overdenture insertion.
