1. WAX CONTOURING
PROSTHEASY
Wax Contouring The process of carving the denture base to simulate the
contour o the natural tissues that are being replaced by the denture , These carving are
made in wax after the teeth have been arranged .
The form of the polished surface influences stability, retention,
esthetics, lip and cheek support and avoid lip and cheek biting
Benefits of properly contoured dentures
1. Facilitate stability and control
2. Improve retention, tolerance and comfort
3. Improve esthetics
4. Provide for appropriate support and contour of lip and cheek
5. Prevent chronic biting of lip and cheek
Polished surfaces of
denture
Concave to conform to the tongue and cheek so the muscles will grip and
tend to seat the denture
Gingival contour reproduced and the proper amount of tooth must be exposed
The interdental
papilla
flat or slight concave to provide more natural appearance
avoiding food impaction.
Gingival roll Convex Gingival roll then slight concavity before periphery of the
denture This helps to displace the buccal mucosa away from the biting zone
cuspid eminence Proper development of cuspid eminence provides lip support and contour,
and helps displace corners of the mouth and the lip away from the biting zone
Stippling Esthetics reflection of light .
Keeps food particles from travelling up to the periphery of the denture
Palate smooth and around 2mm thick
1. This will promote proper speech articulation
2. reduce incidence of gagging
3. provide adequate strength
Carving the gingival
margin
with a knife held at 45° angle to the cervix of the teeth to give
clean cut in the wax.
Final Wax-Up No wax on teeth surfaces
Wax has been carefully smoothed
Natural anatomic contours
Butt joint between wax and teeth
