Working with Dental Crown & Bridge Resin TEMP
Is Dental Crown & Bridge Resin easy to machine?
Post-cured parts trim, grind and adjust readily with carbide burs and diamond discs at moderate speed; use water/vacuum for dust and avoid heat build-up that chips margins.
Can Dental Crown & Bridge Resin be welded?
Not weldable — thermoset network; repairs are made by bonding flowable light-cure composite to a roughened, silanated surface.
Can Dental Crown & Bridge Resin be formed, bent or molded?
Vat photopolymerization only (SLA/DLP/LCD at 385 or 405 nm, 50–100 µm layers); shake/stir the pigmented filled resin before printing, then wash in fresh IPA for the validated short cycle and post-cure under inert gas or glycerin to full conversion.
What surface finishes work on Dental Crown & Bridge Resin?
Finish with fine silicone points and pumice, then a diamond polishing paste or light-cure glaze for a plaque-resistant, tooth-like gloss.

Dental Crown & Bridge Resin TEMP — frequently asked
What is Dental Crown & Bridge Resin TEMP used for?
Dental Crown & Bridge Resin TEMP is typically used for temporary crowns, provisional bridges and veneers. In short: tooth-shaded filled resin; wear-resistant restorative grade; temporary to permanent options.
What is the tensile strength of Dental Crown & Bridge Resin TEMP?
Dental Crown & Bridge Resin TEMP has a typical tensile strength of 55 MPa (7.98 ksi) — stronger than 61% of polymer grades. Strength varies by condition: see the 4 listed tempers.
Is Dental Crown & Bridge Resin TEMP easy to machine?
Reasonably — machinability is rated good (62/100, better than 60% of polymer grades). Post-cured parts trim, grind and adjust readily with carbide burs and diamond discs at moderate speed; use water/vacuum for dust and avoid heat build-up that chips margins.
Can Dental Crown & Bridge Resin TEMP be welded?
Not weldable — thermoset network; repairs are made by bonding flowable light-cure composite to a roughened, silanated surface.
What surface finishes work on Dental Crown & Bridge Resin TEMP?
Finish with fine silicone points and pumice, then a diamond polishing paste or light-cure glaze for a plaque-resistant, tooth-like gloss.
Can Dental Crown & Bridge Resin TEMP be formed, bent or molded?
Vat photopolymerization only (SLA/DLP/LCD at 385 or 405 nm, 50–100 µm layers); shake/stir the pigmented filled resin before printing, then wash in fresh IPA for the validated short cycle and post-cure under inert gas or glycerin to full conversion.
What is the maximum service temperature of Dental Crown & Bridge Resin TEMP?
Dental Crown & Bridge Resin TEMP is rated for continuous use to about 70°C (158 °F), and briefly to 120°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Dental Crown & Bridge Resin TEMP and Dental Crown & Bridge Resin SHADE?
TEMP is the default condition — standard chairside temporary crowns, bridges, inlays and long-span provisionals worn up to about 30 days. SHADE: same base chemistry pigmented to a VITA shade; pick to match the patient's dentition — mechanical properties are essentially unchanged, only optical values shift.
