Can Temrex (multipurpose cement) be used for temporary placement of a veneer?

Temrex Multipurpose Cement for Temporary Veneer Placement

Direct Answer

No, the provided evidence does not address Temrex multipurpose cement or its use for temporary veneer placement, as all available studies focus on orthopedic bone cement (polymethylmethacrylate) for surgical procedures or final cementation protocols for dental veneers—not temporary cementation of veneers.

Evidence Analysis

The search returned no relevant guidelines or research specifically addressing:

• Temrex cement properties or indications
• Temporary cementation protocols for veneers
• Comparison of provisional cements for veneer try-in or temporary placement

What the Evidence Actually Covers

Orthopedic Cement Applications:

• The guidelines discuss polymethylmethacrylate (PMMA) bone cement for cementoplasty in bone metastases and hip arthroplasty 1
• These applications are entirely unrelated to dental veneer cementation

Dental Veneer Cementation:

• Research addresses final cementation using resin-based cements for permanent veneer placement 2, 3
• One study evaluated provisional cements (eugenol-free, calcium hydroxide, light-cured) but focused on their effect on final bond strength after removal, not their use for temporary placement 4

Critical Finding from Provisional Cement Study

The only relevant dental evidence shows that provisional cement selection significantly impacts final restoration bond strength:

• Light-cured provisional cements showed the lowest final bond strength values when used before definitive cementation 4
• Calcium hydroxide provisional cement with cleaning using a dental explorer produced better outcomes for subsequent final cementation 4
• This suggests that if using any provisional cement for temporary veneer placement, the choice matters for the ultimate restoration success 4

Clinical Guidance Gap

Without specific evidence for Temrex cement and temporary veneer placement, I cannot provide a definitive recommendation based on the available literature. The decision would require:

• Manufacturer's instructions for Temrex cement
• Specific indications for temporary vs. permanent use
• Compatibility data with veneer materials
• Effect on final bond strength after removal

General Principles (Based on Available Evidence)

If considering any provisional cement for temporary veneer placement:

• Avoid materials that may compromise final bond strength 4
• Ensure complete removal is possible without damaging the veneer or tooth preparation 4
• Consider that contamination from provisional materials can reduce final cementation success 3
