Evaluation of a new biodegradable membrane to prevent gingival ingrowth into mandibular bone defects in minipigs

Abstract

The experimental PEG membrane applied in the present study successfully prevented collapse of the covering soft tissues to a degree similar to the PLA membrane. The combination of a collagen sponge and the PEG membrane showed the least soft-tissue ingrowth at 10 days and promoted more bone formation at 21 days.
