The cost of rehabilitation of the problematic mandibular complete denture with an implant-retained overdenture, or implant-supported fixed prosthesis, is outside the financial scope of many compromised denture patients especially in developing countries. A more affordable treatment alternative is therefore desirable. The purpose of this study was to ascertain whether simplifying mandibular overdenture treatment utilizing two stages surgery and delayed prosthetic loading of a single implant, will achieve similar patent satisfaction rates and maximum biting force similar to that expected using conventional technique with mandibular overdenture supported by two implants. A 28 completely edentulous patients were selected with mean age of 58.2 years. For all patients Complete denture was constructed in usual manner and they are assigned randomly into two equal groups. Group1 received one midline implant whereas group 2 received two interforaminal implants to retain the mandibular overdenture. Patient satisfaction was assessed using100mm VAS scale and biting force was assessed by using load star sensor, for all patients at baseline,3,6 and 12 months follow up period
