Brief Summary

Evaluation of PEEK versus Titanium Bar Attachments with Implant Assisted Mandibular Complete Overdenture fabricated by CAD/CAM Technology measuring retention of the overdenture and implant evaluation for 6 months and one year

Conditions

Edentulism in Lower Jaw

Outcome Measures

Primary Outcomes (1)

• retention of mandibular overdenture

  Retention of the mandibular implant-assisted complete overdenture will be measured using a digital force meter. Measurements will be taken at 6 months and 12 months after denture insertion.

  6 months and 12 months post-insertion

Eligibility Criteria

• Age: 45 Years - 60 Years
• Sex: male
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Completely edentulous patients free from systemic diseases that may affect soft or hard tissue healing.
• Patient's age ranges from 40 to 60 years old.
• The bone quality and quantity of the mandibular alveolar ridge must fulfill the criteria for implant placement.
• They have normal class Ӏ maxilla-mandibular relationship and sufficient inter-arch space with at least 25mm for bar attachment.
• They have good oral hygiene.

You may not qualify if:

• Systemic disorders that may influence soft or hard tissue healing as oral diseases.
• Patients with history of radiation therapy in the head and neck region.
• Patients with neurological or psychological problems that may impair good oral hygiene.
