Titanium removable denture based on a one-metal rehabilitation concept

Area of Science:

• Biomaterials Science
• Dental Materials
• Prosthodontics

Background:

• Preventing galvanic corrosion in dental restorations necessitates using a single metal type.
• Commercially pure (CP) titanium is proposed as the ideal material for this
• one-metal rehabilitation
• concept due to its bioinert properties.

Purpose of the Study:

• To evaluate the feasibility and application of the one-metal rehabilitation concept using CP titanium.
• To discuss the fabrication methods and challenges associated with CP titanium frameworks for dental restorations, particularly removable partial dentures (RPDs).

Main Methods:

• Review of existing literature and fabrication techniques for CP titanium dental restorations.
• Discussion of computer-aided design/computer-aided manufacturing (CAD/CAM) and laser welding applications for titanium frameworks.
• Analysis of challenges in milling complex RPD framework geometries.

Main Results:

• CP titanium frameworks have demonstrated long-term durability without catastrophic failure.
• Current fabrication methods, including CAD/CAM and laser sintering, face challenges with complex RPD designs.
• Laser welding is a viable technique for repairing and rebuilding titanium frameworks.

Conclusions:

• The one-metal rehabilitation concept using CP titanium is a viable and recommended approach for dental restorations.
• Despite ongoing laboratory and clinical challenges in fabrication, CP titanium's bioinert nature makes it suitable for widespread application.
• Further advancements in manufacturing techniques are needed to overcome complexities in RPD framework production.
