Summary

The goal of this \[type of study: clinical trial\] is to \[investigate the influence of Oversized Drilling Versus Traditional for implant Stability and Crestal Bone Loss.\] in \[ Healthy Patient aged between 20 and 60 years with one missing tooth in the posterior mandible with sufficient bone dimensions\].

The main question\[s\] it aims to answer are:

the influence of oversized drilling versus traditional drilling in the mandibular arch, in terms of implant stability and crestal bone levels. The effects of oversized protocol have not been fully explored on the more compact mandibular bone.

Participants will Control Group: Under-sized drilling group (UD):

Manufacturer-recommended implant osteotomy preparation will be done according to the manufacturer guidelines with the final drill the same diameter of the implant. Intervention Group: oversized drilling (OD) Osteotomy preparations for the oversized drilling group will include an extra drill, which will be 0.2mm wider than the diameter of the implant.

* Once the osteotomy is ready, the appropriate implant will be placed manually at first and then progressed using a ratchet.
* After the implant is correctly placed, a smart peg will be attached to the implant via hand screwing, to measure its stability using Ostell and four readings will be recorded: a mesial, distal, buccal and lingual reading.
* The smart peg will then be removed and will be replaced with a healing collar above the gingival margin.
* The flap will then be sutured back to its original position around the healing collar with an interrupted 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.

Interventions

PROCEDURE

implant placment

* 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.
