80 patients who presented at Wonkwang University Dental hospital with craniomandibular disorders were collected for this study. To observe the occlual contact pattern such as contact numbers, contact force and presence or absence of anterior
occlusal
contact, the author used T-Scan system (Tekscan, Inc, U.S.A) which are computerized occlusal analysing system. And to study the correlation between craniofacial profile and occlusal contact pattern, cephalogram were also taken. The cephalometric
items
related to growth pattern, jaw bone relation and denture patern were measured and analysed according to routine method by computerized program. The obtained data were statistically processed with SPSS/PC+ package about anterior contact pattern
and
its
craniofacial relationship.
@ES The obtained results were as follows:
@EN 1. In terns of growth pattern, patients without anterior tooth contacts showed a tendency to downward growth of craniofacial profile. The value in this subjects were significantly different from the value of patients with anterior tooth
contacts in
items of low gonial angle, jarabak ratio, SN to GoMe angle, FMA, occlusal plane to mandibular plane angle and ramus height.
2. In terms of jaw bone relationship, patients without anterior tooth contacts showed a tendency to backward growth of craniofacial profile. The value of this patients were significantly different from the value of patients with anterior tooth
contacts
in items of SNB, ANB mandibular plane to anterior cranizal base ratio, SNPo, NAPo and APDI items.
3. But in denture pattern, no statistically significant difference by the presence or absence of anterior tooth contacts were showed between this patients groups.
4. From this study, it could be proposed that anterior open bite in the patients with craniomandibular disorders would be originated from not dental discrepancy but skeletal discrepancy.
