Methylenediphenyl diisocyanate (MDI) was used as the chain extender for low molecular weight poly(lactic acid) (PLA) to produce high molecular weight biodegradable polymer material with a better heat resistance. PLA prepolymer with a number-average molecular weight (M n ) of 5800 and a weight-averag
## Abstract Guided tissue regeneration (GTR), in periodontal therapy, involves the placement of a barrier membrane, to ensure the detached root surface becomes repopulated with periodontal ligament cells capable of regenerating this attachment. GTR procedures exhibit large variability in surgical o
