LactoSorb®
Resorbable Fixation System
An absorbable plating system.
The LactoSorb Resorbable Fixation System is a simplified surgical system designed to provide convenience to surgeons and O.R. staff while improving the overall efficiency of the surgical procedure.
The science behind LactoSorb
LactoSorb is a fixation system made of completely resorbable material for guided bone regeneration.
LactoSorb comprises of 82% L-lactic acid (PLLA) and 18% glycolic acid (PGA). This unique formulation incorporates the high strength properties of PGA with the intermediate absorption characteristics of PLLA to form a biocompatible, resorbable copolymer that retains over 80% of its mechanical strength during the first eight weeks of healing with complete mass loss occuring in 9 – 15 months.
Resorption in Approximately One Year or Less
At initial placement, LactoSorb is comparable to that of titanium plating and it retains approximately 70% of its strength at eight weeks, allowing for complete osseous union in the craniomaxillofacial skeleton.
