What is Denture Base Resin?

Denture Base Resin is a biocompatible SLA/DLP photopolymer supplied in pink (PINK, PINK-LT, PINK-DK, PINK-OPQ), clear, high-impact and flexible variants, formulated to denture-base polymer standards, with an MDR Class IIa option. Dental labs choose it for printed removable bases, reaching 48 MPa tensile strength, 4 % elongation, 82 Shore D and a 105 °C glass transition after the validated post-cure. Maximum service temperature is 60 °C, so parts must not be boiled or autoclaved, and the crosslinked network cannot be welded or re-melted — repairs rely on self-cure PMMA. For tooth-shaded restorations use Crown & Bridge Resin. Denture Base Resin has a density of 1.18 g/cm³ (0.0426 lb/in³), heavier than 50% of polymer grades. Its glass-transition temperature is 105°C (221 °F). Denture Base Resin has a yield strength of 45 MPa (6.53 ksi) and a tensile strength of 48 MPa (6.96 ksi) — weaker than 58% of polymer grades. Elongation at break is 4% and the elastic modulus is 2.2 GPa (0.319 Msi).

Working with Denture Base Resin

Is Denture Base Resin easy to machine?

Trim sprues and adjust intaglio with carbide acrylic burs or tungsten trimmers at low speed with wet/vacuum dust extraction; avoid heat build-up that crazes the surface.

Can Denture Base Resin be welded?

Not weldable; repairs and relines are done chemically with self-cure PMMA or a matching light-cure repair resin after roughening and monomer wetting.

Can Denture Base Resin be formed, bent or molded?

Print at 25–35 °C vat temperature, 50–100 µm layers, orient the base 20–30° with supports on the polished flange side; wash in fresh IPA (≤5 min total to avoid softening) and post-cure in a nitrogen/glycerin-free UV oven per the validated cycle.

Denture Base Resin — frequently asked

What is Denture Base Resin used for?

Denture Base Resin is typically used for removable denture bases, denture try-ins and denture repairs. In short: denture-standard biocompatible resin; full pink shade range; 105 °C glass transition.

What is the yield strength of Denture Base Resin?

Denture Base Resin has a typical yield strength of 45 MPa (6.53 ksi) and a tensile strength of 48 MPa (6.96 ksi) — weaker than 58% of polymer grades. Strength varies by condition: see the 7 listed tempers.

Is Denture Base Resin easy to machine?

Reasonably — machinability is rated good (65/100, better than 66% of polymer grades). Trim sprues and adjust intaglio with carbide acrylic burs or tungsten trimmers at low speed with wet/vacuum dust extraction; avoid heat build-up that crazes the surface.

Can Denture Base Resin be welded?

Not readily — weldability is rated not recommended (5/100). Not weldable; repairs and relines are done chemically with self-cure PMMA or a matching light-cure repair resin after roughening and monomer wetting.

What surface finishes work on Denture Base Resin?

Bond teeth with the matching adhesive resin, then finish with pumice and acrylic high-shine compound; steam-clean rather than boil, and never autoclave or use alcohol-based disinfectants long-term.

What is the maximum service temperature of Denture Base Resin?

Denture Base Resin is rated for continuous use to about 60°C (140 °F), and briefly to 80°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between Denture Base Resin PINK and Denture Base Resin Flex?

PINK is the default condition — default gingival-pink shade, washed and fully post-cured; use for production removable full/partial denture bases. Flex: elastomeric-modified printable base for flexible partials and soft-clasp appliances; not a substitute for rigid ISO 20795-1 Type 1 bases. Yield strength is 45 MPa in PINK versus 15 MPa in Flex.
