Basal compressive implants, complete overdenture for atrophied edentulous mandibular ridge: Clinical and radiographic study
Brief summary
The aim of the present study will be clinical and radio graphical comparison of four basal and compressive implant designs will be installed in the interforamina area of atrophied edentulous mandible and immediately loaded by screw retained mandibular overdenture . Implant design comparison will be done clinically and radiographically after one and two years of implant loading
Detailed description
Patients will be divided randomly in to 2 equal groups: * Group1: this group will receive immediate loaded screw retained complete overdenture supported by 4 basal implants design . * Group2 :this group will receive immediate loaded screw retained complete overdenture supported by 4 compressive implants design * After final implant placements, they will be immediately scanned by intraoral scanner to construct milled in titanium bar which will be immediately screwed into the implants * Mandibular screw retained complete overdenture will be constructed. Evaluation will be for: * Peri implant tissue health that will be measured according to mombelli(12) at the time of insertion(T0), 6months(T1) and 12months (T2). * Marginal bone height changes will be measured using standardized digital panoramic x-ray(13) after 6months (T0), 12month(T1) and 24months(T2) after prosthesis insertion. * Periotest will evaluate the stability of the implants during implantation (T0) , 3months(T1) and 6months(T3) following surgery(14) .
Interventions
DEVICEBasal Dental implant
