Wax Try-in - 64
Sibilant sounds (‘S’, ‘Z’‘T’ ‘CH’ ‘SH’, ‘sixty-six’, ‘Mississippi’) - upper and lower
incisors should approach end to end relationship
Fricative sounds (F, V, ‘Fifty-Five’ , ask patient to count from 50 to 60) - upper incisal
edges should just touch the posterior one third of the lower lip
7. Denture base contours
Denture base contours can affect phonetics, comfort and retention. In general, the
denture bases should not be convex in shape.
Remove excess wax to provide room for tongue if you note the patient struggling with
phonetics, or noting that they do not have enough tongue space. Ensure that the denture
base is not unduly thick or thin. Excess bulk will impair comfort, and a base that is too
thin will be structurally weakened.
8. Patient Input
At any point in the try-in appointment, ask for patient input, using open ended questions
(“How do you like the appearance?” rather than “Don’t the new dentures look great?”).
If the patient sounds unconvincing in their approval of the setup, attempt to get more
information by asking further questions. Do not let the patient dissuade you that the wax
try-in stage should be rushed in the interest of saving time.
