Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

the purposse of the study To evaluate the effect of implant supported hybrid prostheses on the bone of the supporting structure of edentulous mandible using Polyetherketoneketone (PEKK) framework versus cobalt chromium framework. fourteen female patients with lower single edentulous ridges are chosen with adequate dental hygiene, enough interarch space and free of systemic diseases and parafunctional habits. Patients who received new single dentures are randomly allocated into each group using computer software program and five intraforaminal implants were inserted parallel using surgical guide.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patient's approval:

* All patients will be informed in details about the nature of the investigation and the aim of the study. They will agree to take part in the study and will sign on an informed consent form.
* All participants will be given notice about their privacy practices, their legal duties and their rights.
* In case of implant treatment failure, the patients will receive a new well-fitting denture.

Patient's grouping:

In this study there will be two equal groups, grouping will be based on the material that will be used for framework construction:

Group I: framework will be fabricated using PEKK. Group II: frame work will be fabricated using cobalt chromium alloy.

Clinical steps:

Pre-prosthetic phase:-

* Conventional single lower denture will be made for all patients.
* Occlusal adjustment of upper teeth will be done for all patients.
* The single lower denture will be duplicated with radiographic markers and CBCT will be used to determine exact position of implants.

Surgical phase:-

* Five conventional implants in intraforaminal area will be placed according to the planned cone beam CT using surgical guide to accurately place the implants.
* Postoperative analgesics and anti-inflammatory medications will be described.
* After osseointegration, second surgery will be carried out and healing abutment will be screwed for each implant.

Prosthetic phase:-

* After healing period open top tray impression will be made.
* Jaw relation record will be taken using record bases and wax rims.
* Group I: The PEKK framework will be milled using milling machine.
* Group II: cobalt chromium framework will be made with wax pattern milling then casted by conventional method.
* The PEKK framework will be veneered with zirconia and the cobalt chromium will be veneered with porcelain.
* Implant supported fixed detachable prostheses using PEKK framework or cobalt-chromium framework will be screw retained to conventional implants.
