Working with Dental Surgical Guide Resin FAST
Is Dental Surgical Guide Resin easy to machine?
Light bur trimming, sleeve-bore reaming and support-nub removal only — use sharp carbide/tungsten burs at moderate speed and light pressure; the cured thermoset chips and heat-smears if fed hard.
Can Dental Surgical Guide Resin be welded?
Not weldable; repairs and sleeve bonding are done with light-cure flowable composite or cyanoacrylate/methacrylate adhesive.
Can Dental Surgical Guide Resin be formed, bent or molded?
Printed on 385/405 nm SLA-DLP-LCD at 50–100 µm layers; orient the guide occlusal-side-down at 15–30° to keep drill bores support-free, then wash in fresh IPA (short cycle) and post-cure per IFU (e.g. 60–80 °C under N2 or in a nitrogen/heated cure unit) — properties and biocompatibility are only valid after full post-cure.
What surface finishes work on Dental Surgical Guide Resin?
No plating or anodising; finish is bur trim plus fine abrasive and cloth polish. Avoid over-soaking in solvent, dry-heat sterilise never above Tg, and store finished guides dark to limit yellowing.
Dental Surgical Guide Resin chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| urethane dimethacrylate (UDMA) oligomermain crosslinking oligomer backbone | 30 – 70 | 50 |
| Bis-EMA / Bis-GMA type methacrylategrade dependent; raises Tg and stiffness | 0 – 30 | 15 |
| nano/micro silica or glass fillersome grades unfilled for clarity | 0 – 15 | 5 |
| photoinitiator (TPO / BAPO type, 385–405 | 0.3 – 2.5 | 1.2 |

Dental Surgical Guide Resin FAST — frequently asked
What is Dental Surgical Guide Resin FAST used for?
Dental Surgical Guide Resin FAST is typically used for dental implant surgical guides, drill guides and temporary intraoral appliances. In short: class I/IIa biocompatible; sterilisable guide resin; post-cure critical to certification.
What is the tensile strength of Dental Surgical Guide Resin FAST?
Dental Surgical Guide Resin FAST has a typical tensile strength of 52 MPa (7.54 ksi) — stronger than 56% of polymer grades. Strength varies by condition: see the 4 listed tempers.
Is Dental Surgical Guide Resin FAST easy to machine?
Reasonably — machinability is rated good (56/100, worse than 56% of polymer grades). Light bur trimming, sleeve-bore reaming and support-nub removal only — use sharp carbide/tungsten burs at moderate speed and light pressure; the cured thermoset chips and heat-smears if fed hard.
Can Dental Surgical Guide Resin FAST be welded?
Not weldable; repairs and sleeve bonding are done with light-cure flowable composite or cyanoacrylate/methacrylate adhesive.

What is the maximum service temperature of Dental Surgical Guide Resin FAST?
Dental Surgical Guide Resin FAST is rated for continuous use to about 65°C (149 °F), and briefly to 121°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Dental Surgical Guide Resin STD-CLR and Dental Surgical Guide Resin AC-HT?
STD-CLR is the default condition — default choice for implant drill guides and pilot guides printed on SLA/DLP/LCD dental printers and autoclaved at 121 °C. AC-HT: pick when the guide must survive repeated 134 °C prevacuum autoclave cycles without warping or losing bore accuracy.
