ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to methods for regeneration of mucosa.
2. Discussion of the Background Art
The use of split thickness skin grafts and oral mucosal free grafts in vestibular deepening and other types of vestibuloplasty surgery in the oral cavity has been an established procedure for some time. In addition, the use of free mucosal grafts taken from the palate and from the buccal mucosa has been used in re-establishing attached mucosal surfaces in edentulous alveolar ridge areas particularly in conjunction with the use of root form implants.
While such grafting procedures are well established, the development of an effective alloplastic or xenogeniec substitute graft material for the reconstruction and regeneration of normal mucous membrane would bring about a much wider application of vestibuloplasty surgical procedures.
There remains a need in the art for improvements in promoting regeneration of mucosa in general and, in particular, following vestibuloplasty surgical procedures.
SUMMARY OF THE INVENTION
In accordance with the present invention, mucosa regeneration is promoted utilizing a membrane comprised of a purified collagen material derived from natural collagen-containing tissue.
