Effect of PEEK and Titanium Framework Reinforcement on Marginal Bone Loss Around Implants Supporting a Fixed All-on-four Prosthesis in Completely Edentulous Mandibles

Effect of PEEK and Titanium Framework Reinforcement on Marginal Bone Loss Around Implants Supporting a Fixed All-on-four Prosthesis in Completely Edentulous Mandibles. A Randomized Controlled Clinical Trial

• Status: Active Not Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 20 (actual)
• Sponsor: Cairo University · Academic / Other
• Sex: All
• Age: 45 Years – 60 Years
• Healthy volunteers: Accepted

Summary

A fixed all-on-four prosthesis will be constructed for the lower arch for each patient and the marginal bone loss will be evaluated at baseline, 3,6,9 and 12 months.

Conditions

• Prosthodontics
• Implants, Dental
• Prosthesis
• Bone Loss, Alveolar

Interventions

Type	Name	Description
OTHER	Titanium framework reinforced all on four prosthesis	Titanium frameworks provided many advantages as their biocompatibility, corrosion resistance, relatively lower weight and high mechanical properties as well as avoiding the casting errors and technique sensitivity
OTHER	PEEK framework reinforced all on four prosthesis	Fabricating a fixed prosthesis for patients with completely edentulous mandibles reinforced with PEEK
