Bioresorbable barrier membranes are widely used in dentistry and maxillofacial
surgery. When the membranes are placed over bony defects and closely adapted to the
surrounding bone face, an environment that prevents invasion of competing nonosteogenetic
cells from the overlying soft tissues can be created. The purpose of the present study was to
establish whether there is an influence of production of different polymeric and composite
membranes on physico-chemical properties, synthetised in our laboratory.
Physico-chemical properties were analyzed by differential scanning calorimetry
(DSC), scanning electron microscopy (SEM) with energetic dispersive spectroscopy (EDS),
inverse gas chromatography (IGC) and tensile strength test (TST).
Membranes with poly-l-lactides of 100000 and 430000 g/mol molecular weight have
shown the highest degree of crystallinity. Membranes with poly-l-lactides of the greatest
molecular weight have shown the highest tensile strength value, as expect...ed. Surface
microstructure, depending on the parameters of processing, was perforated with smaller or larger
pores. Composite membranes with hydroxyapatite have a brittle fracture while determining
tensile strength test, unlike polymer membranes whose fracture is classical for polymers.
Biocompatibility is in the direct connection with surface free energy. Consequently,
obtained surface free energy values indicate good biocompatibility of bioresorbable barrier
membranes.
