LeadFIX is a bioresorbable membrane pin made from polylactide. The clinical use of resorbable membranes for guided bone regeneration constitutes a new approach in dental surgery. LeadFIX is a bioresorbable augmentation system used to fix membranes in position. Total membrane stability is an important pre-requisite for successful, guided bone regeneration. Application of the LeadFIX-augmentation system prevents any relative movement between the membrane and surrounding bone or membrane an mucoperiostal flaps. It ensures an intact seal and smooth transition to the periosteum. The membrane becomes securely fixed in position over several months.

PolyPIN is a bioresorbable bone pin from polylactide. Metal implants are normally removed in a second operation, once the bone has healed.
This not only means additional expense, but is also stressful for the patient! What is more, a second stay in hospital is necessary to remove the metal, involving absence from work and increased risk of complications. The ideal osteosynthesis implant should, therefore, simply dissolve after it has fulfilled its stabilising or fixing task, without subjecting the body to an additional burden in doing so. The Polypin is such an implant. It is a pin made of a polylactide copolymer (Poly L/D, L- Lactide 70/30). Thanks to the material it is made of and the way it is designed, it offers significant advantages.

BetaBASE is a bioresorbable bone replacement from microporous and macroporous β-tricalcium phosphate. BetaBASE consists of pure-phase β-TCP. Potential risks of infection involved in the use or processing of biological material (HIV, BSE, inter alia) are non-existent with BetaBASE. BetaBASE has an interconnected pore system with micropores and macropores that reproduce the well-known osteoconductive effect almost perfectly. Osteoblasts and blood vessels are able to proliferate rapidly in the open pore system and grow swiftly in the BetaBASE. This also enables internal resorption of the materials. The high overall porosity of BetaBASE (> 60 %) means that the body has to break down a far smaller quantity of bone replacement material, based on the volume of the defect. This accelerates the resorption process and also creates new opportunities to fill large bone defects.

BioBASE is a bioresorbable bone replacement from microporous and macroporous α-tricalcium phosphate. Biobase is an inorganic, bioresorbable bone replacement from pure-phase α-tricalcium phosphate. BioBASE is a bone replacement for temporarily filling pathological, traumatic and postoperative bone defects. Biobase has a system of micropores (< 5 μm) and macropores (max. 1 mm) with a porosity of approx. 65%. This creates a far larger material surface, which enhances the reaction kinetics in the resorption processes. Biobase has a special surface structure which increases the level of calcium elution, and promotes ossification. BioBASE is broken down to the same extent as it forms new bones. Duration of resorption: 6 to 14 months. Blood vessels and osteoblasts grow in the macropores and guarantee rapid proliferation of the new bone substance. Tissue fluid penetrates the pore system, thereby enabling a complete hydrolitic breakdown of the material.
