Is to compare between the conventional drills versus osseodensification drills for implant stability and peri-implant marginal bone loss in maxillary implant overdenture.
Comprehensive clinical examination and understanding of patient's chief complaints and their expectations from the prosthesis. * medical and dental history * A complete denture will be constructed for each patient to aid in the scan technique, if the patient has an denture, it will be evaluated to be used. * The complete denture will be constructed following conventional denture fabrication procedures. * CBCT radiograph will be taken for bone height and width, and identify the vital structures before implant placement. * A surgical guide will be used to aid in the implant placement, each patient will be scheduled for surgery to insert four root form implants. Each patient will receive four implants at canine and premolar regions from the same implant manufacturer. Study group: The osseodensification drilling group (G1), bone preparation was performed using tapered multifluted burs (Densah Bur; Versah, MI, USA) at 800- 1200 rpm counterclockwise rotation under saline irrigation. Drilling to the desired depth using the tapered densah pilot drill with speed of 800-1200 rpm with copious irrigation without any lateral pressure with clock wise motion. Control group: In the conventional drilling group (G2), drilling the other contralateral sites of bone using the conventional sequential drilling system according to the manufactural instruction. * All patients received 2gm/day amoxicillin, clavulanate and 50 mg/8 hours non-steroidal anti-inflammatory analgesics for 5 days postoperatively. Postoperative instructions included a soft diet and appropriate oral hygiene measures with 0.2% chlorhexidine mouth rinse. * After four months, the implants will be exposed and attachment (stud attachment) will be screwed to the implants. Then, overdenture pick-up is done. \* Number of visits \& follow up period * 5 visits for construction of denture * 1 visit for CBCT * 1 visit for implant insertion * 1 visit for attachment placement and pick-up of overdenture * Patients will be recalled at base line,4 and 7 weeks 4 and 12 months following implant insertion for outcomes assessment

RECRUITINGPeri-implant marginal bone loss
Radiographic follow up will be performed for marginal bone loss. Serial of standardized digital periapical radiographs using; long cone paralleling technique, XCP periapical film holder and an individually constructed radiographic acrylic template will be taken at the time of implant placement (base line) then at 4,12 months.
Time frame: 1 year
Implant stability measurements
The Osstell will be used according to the manufacturer's instructions and held perpendicular to the provided implant smart peg. Osstell values (ISQ) are going to be obtained for the bucco-lingual, mesio-distal surfaces of each implant. Three measurements will be made for each surface and the mean will be obtained for statistical analysis.for each implant will be done at the time of surgery, at 4 weeks , 7weeks and 4 months
Time frame: 4 months
