Biocompatible Glasses - precision made bioactive and bioinert glasses

Mo-Sci Health Care has extensive experience in the manufacture of biocompatible glasses. These compositions can be either bioinert or bioactive. Bioactive glasses have the ability to bond to soft or hard tissue. These glasses can also be biodegradable and are either dissolved or resorbed in the body. Our staff of glass engineers and technicians can research, develop and produce glass which is custom-made to fit your particular application.

Manufacturing Facilities Great care is taken in the manufacturing (batching, melting, grinding and packaging) of these specialized glasses to assure that they meet the high standards for medical products. These glasses are made from high purity (analytical and reagent grade) chemicals, keeping unwanted trace impurities to a minimum.

Composition and Properties

Standard compositions include 45S5 and 13-93 bioactive glasses. Custom compositions are available upon request.

• Thermal Exp. 160 x 10^-7 cm/cm/°C

Uses

Bioactive glasses are available in a wide variety of different forms, ranging from cast shapes, quenched frit, rods, fibers, disks, spheres and micro-sized powders. These can be surface-treated or modified as needed for particular applications.

Uses include:

• Implants
• Repair of periodontal defects
• Cranial and maxillofacial repair
• Bioactive coatings
• Fiber reinforcement for composites
