Abstract
ABSTRACT
Background
Along with peripheral seal, palatal throat form also has significant value to achieve
good retention and stability of maxillary complete denture. The palatal throat
form also determines the posterior extention of maxillary dentures and affects the
comfortability of the patients.
Objective
To analyse the palatal throat form in a Nepalese population based on age, gender
malocclusion and facial divergence.
Method
This study consisted of 300 randomly selected radiographs with a mean age of
21.46±5.62 years. Skeletal malocclusion in lateral palatal throat form outlines. Patient
were also categorized according to different Schudy’s facial divergence angle (SN-
MP). The obtained data was tabulated based on the age, gender, palatal throat form,
type of malocclusion and facial divergence. The results obtained were subjected to a
statistical analysis to find the relation between variants of the soft palate and types
of malocclusion in different gender groups.
Result
Proportion between palatal throat form and malocclusion found to be significant.
There is no significant difference in proportion of different class of palatal throat form
between genders. Whereas Class II palatal throat form found to be most common in
all facial divergence.
Conclusion
It was observed that Class II malocclusion was most common among three types. The
relation between palatal throat form and malocclusion, was found to be statistically
significant.
