G-BLOCK – Graphenano Dental

The Next Evolution in Graphene-Reinforced CAD/CAM Bio-Polymers

Overview

G-BLOCK (widely recognized through Graphenano’s breakthrough G-CAM technology) is a cutting-edge, PMMA-based polymer disc enhanced with medical-grade graphene nano-reinforcement. Engineered specifically for CAD/CAM milling, this advanced biopolymer redefines the standards of digital dentistry—offering an optimal, metal-free balance of superior mechanical strength, lightweight comfort, and lifelike aesthetics.

By bridging the gap between traditional plastics and heavy ceramics, G-BLOCK delivers a high-performance alternative for both temporary and permanent dental restorations.

Key Features & Clinical Advantages

• Graphene Nano-Reinforcement: Doping conventional PMMA with graphene drastically improves structural integrity, granting exceptional resistance to flexion, fracture, and crack propagation under repetitive masticatory forces.

• Ultralight & Patient-Friendly: Unlike heavy zirconia or metal-ceramic restorations, G-BLOCK provides an exceptionally lightweight profile. This significantly boosts patient comfort—especially in full-arch or implant-supported cases—while eliminating the harsh "click-clack" acoustic feedback of traditional materials.

• Superior Biocompatibility: Formulated to be entirely free of metals and exhibit minimal residual monomer content (<0.004%), G-BLOCK is chemically inert, highly tissue-friendly, and features natural bacteriostatic properties that help reduce bacterial colonization.

• Streamlined Laboratory Workflow: Designed for maximum efficiency, G-BLOCK eliminates the need for time-consuming sintering or vitrification processes. Labs can machine complete, high-precision restorations rapidly, saving production time and lowering overall processing costs.

• Kind to Opposing Dentition: Offers a balanced surface hardness (approx. 88 Shore D) that protects opposing natural teeth from aggressive wear and tear.

Indications

G-BLOCK is exceptionally versatile, making it suitable for a wide array of CAD/CAM milled indications, including:

• Permanent single crowns and multi-unit bridges (anterior and posterior)

• Full and partial removable dentures & implant overdentures

• Implant-supported full-arch rehabilitations

• Aesthetic veneers, inlays, and onlays

• Long-lasting provisional/temporary restorations
