Abstract:
Hyperdry amniotic membrane, a novel preservable material derived from the human amnion, has been introduced clinically in ophthalmology and other fields. This membrane is available as a wound dressing material for surgical wounds of the tongue and buccal mucosa but has not been used on wounds of the alveolar mucosa. This paper reports 2 cases in which intraoral alveolar wounds with bone exposure were successfully treated with the use of hyperdry amniotic membrane: a 74-year-old woman with gingival leukoplakia of the edentulous mandible, and a 43-year-old man who underwent vestibuloplasty of the reconstructed mandible. The results indicate that the hyperdry amniotic membrane is a useful dressing material, not only for soft tissue wounds, but also for exposed bone in the oral cavity.
