osspore CAS

micro-pores, and through calcium sulphate resorption
• Osspore CAS BONE VOID FILLER is fast setting, injectable and mouldable ceramic bone graft substitute material intended for bone voids/gaps. Mixing the components, with the liquid to smooth paste for easy injection by injection device, results in a viscous material intended to fill voids in difficult access areas.

Contraindications
• Hypersensitivity to any of the excipients
• Local infection at the site of implantation
• Pregnancy
• Breastfeeding
• Manifest thyroxicosis

Description
OSSPORE CAS BONE VOID FILLER .
The major constituents of the powder are hydroxy apatite and calcium sulfate hemihydrate and TCP. The liquid is saline with radio opaque iodine.. . By combining hydroxy apatite,TCP, and calcium sulfate an optimal balance is achieved between resorption rate and bone in-growth rate. Calcium sulfate acts as a resorbable carrier for hydroxy apatite has a slow resorption rate, high osteo-conductivity promoting bone in-growth and gives long term structural support to newly formed bone.
The ceramic bone substitute material is placed into the bone void under visual inspection or under radiographic monitoring during open or percutaneous surgery.
The paste may be injected into the defect, moulded by hand and digitally placed into the defect, or used to prepare beads that are placed into the defect.
When fully set in vivo,

OSSPORE BONE VOID FILLER is drill able and can be
used to for attachments.
