SOFT TISSUES INJURES EXTENSTION OF MANDIBLE
As alveolar ridge resorption takes place, the attachment of Jl1UCOS<1and muscles near the denture-bearing area – exerts a ‘gre<1ter influence on the retention and stabiltry of dentures. In addition, the amount and quality of fixed tissue over the denture-bearing area may be decreased. Soft tissue” surgery performed to improve denture stability may be carried out alone or may be done after” bony augmentation. In either case the primary goals of soft tisssues.
