Hard Plaster – High Strength Dental Gypsum (Biosurgico)

Hard Plaster – High Strength Dental Gypsum (Biosurgico) is a premium dental gypsum formulated for rapid setting and unparalleled strength. It is engineered to achieve a final compressive strength of 30 N/mm² within 24 hours, making it ideal for detailed intra‑oral impressions, diagnostic casts, and temporary crowns.

Its fast 6–8 minute setting time, combined with a fine particle size of 63 µm, delivers smooth, accurate reproductions while maintaining long‑term durability in clinical settings. This ensures that clinics can produce high‑quality models with minimal waste and reduced chair‑time.

Key Features

• Setting time of 6–8 minutes at 35 °C for quick clinical turnaround.
• Water‑to‑powder ratio precisely 1.6:1 to optimize flow and dimensional stability.
• Compressive strength of 30 N/mm² achieved after 24 hours, meeting ISO 4823 standards.
• Ultra‑fine particles (63 µm) that provide a smooth finish and detailed articulation.
• Pure white colouration for accurate shade matching with dental appliances.
• Antimicrobial additive (chlorhexidine) incorporated for transient cross‑linking and reduced microbial contamination.
• Packaged in 400 g moisture‑controlled sachets for consistent performance and easy storage.
• Shelf life of 24 months at 25 °C with relative humidity below 70 %, ensuring long shelf stability.
• Compliance with ISO 4823, ISO 4052 and USP Class V specifications.
• Low waste formulation: delivers high yield per gram of powder.

Clinical Uses

• Creation of accurate static intra‑oral impressions for full‑arch and single‑tooth cases.
• Pouring of diagnostic casts for treatment planning and case review.
• Fabrication of temporary ceramic and resin crowns that require high dimensional accuracy.
• Moulding reduction templates for metal substructure fabrication in fixed prosthodontics.
• Production of replica models for esthetic strip crowns, veneers, or customised abutments.
• Construction of orthodontic model study systems for wire bending and appliance design.
• Base block creation for complex full‑mouth reconstruction and surgical planning.
• Use as reference material in CBCT simulation and virtual treatment planning workflows.
