Abstract
ABSTRACT
Background
Establishment of occlusal plane with hamular notch- incisive papilla plane as a useful
reference helps to reduce the chairside time taken for jaw relation during complete
denture fabrication.
Objective
To determine the hamular notch-incisive papilla plane (HIP) as a useful reference
plane in establishing the occlusal plane.
Method
This cross-sectional analytical study was conducted among 100 dental students by
obtaining the maxillary cast from an impression made. The data collected were
entered and analyzed using SPSS version 21. Paired t-test, Independent t-test and
Pearson correlation was applied for statistical analysis.
Result
The vertical distance from hamular notch-incisive papilla plane and occlusal plane
at the level of mesio-incisal line angle of maxillary central incisor and mesio-palatal
cusp tips of maxillary first molar showed statistically significant difference (p < 0.001)
on both right and left sides. There was statistically significant difference (p < 0.05)
between hamular notch-incisive papilla plane and occlusal plane on right and left
sides, between right and left mesio-palatal cusp tips of maxillary central incisors from
hamular notch-incisive papilla plane. Hamular notch-incisive papilla plane, mesio-
incisal line angle of right maxillary central incisor and mesio-incisal line angle of left
maxillary central incisor had mild but significant correlation with age. The parallelism
between hamular notch-incisive papilla plane and occlusal plane within the range of
2 mm was 62% on right side and 75% on left side.
Conclusion
Hamular notch-incisive papilla plane can be used as a practical method for establishing
the occlusal plane tentatively.
