Dental Implant Stability Placed in Healed Bony Sites Using Oversized Drilling Versus Conventional Drilling Protocol

"* Crestal incision followed by full thickness mucoperiosteal flap elevation.~* Drilling of the implant according to the manufacturer's instructions to reach the final drill corresponding to the implant size.~* Allocation concealment will be broken at this point to assign the patient into one of two groups:~Control Group: osteotomy preparation the same diameter of the implant. Intervention: oversized drilling:Osteotomy preparations will include an extra drill,(0.2mm) wider than the diameter of the implant.~* A smart peg will then be attached to the implant, to measure its stability using Ostell and three readings will be recorded:occlusal buccal and lingual reading.~* A healing collar will then be place over the implant, then simple intrerupted suture~* A standardized digital periapical radiograph will be taken using a radiographic holder and a custom-made radiographic stent to determine the initial crestal bone level."
