Clinical Evaluation of Stability of Implants Placed in Partially Edentulous Maxilla With Poor Bone Quality Via New Reverse Drilling Technique Versus Osteotome Technique.

Clinical Evaluation of Stability of Implants Placed in Partially Edentulous Maxilla With Poor Bone Quality Via New Reverse Drilling Technique Versus Osteotome Technique: A Randomized Controlled Clinical Trial

The study will compare between osteotome technique and New Reverse Drilling Technique in the placement of dental implant in posterior maxilla , primary outcome will be Implant stability that will be measured by Periotest device . follow up for 6 month.

secondary outcomes will be crestal bone loss , pain and swelling.

Inclusion criteria:

1. Partially edentulous patients in the maxillary posterior region.
2. Systemically healthy patient.
3. Presence of proper inter-arch space for placement of the implant prosthetic part.
4. Sufficient bone height and width for implant placement (bone height ≥10mm and bone width ≥6mm).
5. Non-smoker.
6. Patients who are ≥ 20 years old.
7. Good oral hygiene.
8. Acceptance of a one year follow-up period.
9. Informed consent is provided by the patient.

Exclusion criteria:

1. Patients with systemic conditions that may interfere with implant stability,
2. Patients with local pathological defects related to the area of interest.
3. Unmotivated, uncooperative patients with poor oral hygiene.
4. Patients with habits that may jeopardize the implant longevity and affect the results of the study such as alcoholism or parafunctional habits.
5. Inadequate inter-arch space for implant prosthetic part
