A study comparing the occlusal plane in dentulous and edentulous subjects in relation to maxillomandibular space in Kashmiri population

AUTHOR(S): Mohammad Altaf Tantray, Sandeep Koul Bali and Shabir Ahmad Shah
ABSTRACT:Background: Several techniques have been documented to orient the occlusal plane properly in edentulous patients. Esthetic and phonetic considerations help orient the occlusal plane anteriorly. The intraoral landmarks that help in locating the occlusal plane posteriorly are retromolar pad, lateral border of tongue, parotid papilla and rima oris.
Materials and Methods: After obtaining signed informed consent, the lateral cephalograms of selected participants were taken in the department of Oral Medicine and Diagnostic Radiology, Government Dental College and Hospital, Srinagar Jammu & Kashmir, India. Tracing of each cephalogram was made using a tracing sheet with a 4-H pencil. It consists of the patients who attended the Department of Prosthodontics and Crown & Bridge, Government Dental College and Hospital, Srinagar. The occlusal plane was adjusted parallel to inerpupillary line anteriorly and Camper’s Plane posteriorly during denture fabrication. During the post insertion period, a piece of classic stainless steel matrix band no. 18 that was 10 mm x 4 mm wide and 0.005 inches thick was placed on the lower right occlusal plane with tape tips so that the upper border of the band was aligned with the tips of the buccal cusps of the first and second premolars and the mesio-buccal cusp of the first molar. A strip of anterior band material 0.003 inches thick was placed longitudinally on the maxillary right central incisor and mandibular right central incisor, from the gingival margin on the labial aspect, over the incisal edge, and to the gingival margin on the lingual/ palatal aspects. Right lateral cephalograms were obtained while the dentures were placed in the mouth and the jaws were approximated in centric relation.
Results: The measurements for every patient were recorded and the values obtained were subjected to statistical analysis, including;
1. Mean
2. Standard deviation
3. Co-efficient of variation
4. F-test (Analysis of variance ANOVA).
5. Students t- test
Conclusion: A significant association exists between the inclination of the occlusal plane and maxillary plane in relation to maxillomandibular space dimensions. In the long and low subtype of maxillomandibular space of the dentulous group, the occlusal plane tends to be parallel to the maxillary plane. While as, in the short and high subtype the occlusal plane is more angulated in relation to the maxillary plane. The occlusal plane inclination to the maxillary plane in long and low type is low while as, it is higher in short and low subtype of edentulous group.
