The alveolar ridge line is used to divide the
•Finishing inner areas upper denture (cavity side) and
•Finishing inner undercut areas upper denture machining operations.
If there is no arch curve (tooth crest line), the alveolar ridge is also used to guide the
•Finishing inner areas upper denture (occlusal side) and
•Finishing outer undercut areas full denture machining operations.
