About this trial

The Goal of the clinical trail is to evaluate the Bone height changes around two axially placed anterior implants and two distally inclined 30-degree angle posterior implants in comparison to two axially placed anterior implants and two distally inclined 45-degree angle posterior implants using cone beam CT (CBCT).

Patients will visit the clinic after the surgery and after the framework and denture insertion for check ups and during the follow up periods ( at denture insertion, 6 months and 12 months)

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

All patients' ages must range from 50-65 years old.

All patients' ridges should be covered with firm mucosa free from any signs of inflammation or ulceration and exhibit adequate height and width of the residual alveolar ridge.

Patients should be free from any metabolic or bone disorders that contraindicate implant installation.

All patients must have sufficient inter arch space

Disqualifiers

Patients with oral or systemic diseases.

Patients with xerostomia or excessive salivation.

Patients with parafunctional habits (bruxism or clenching).

Heavy smoker or alcoholic patients.
