Brief Summary

The goal of this clinical trial is to learn about different head position's effect on occlusal contacts during digital interocclusal record. The main question aims to answer is: • Are different head positions in physiological limits can be affected the occlusal contact during interocclusal record? Participants will be asked to stand in three different physiological head positions (neutral, forward and backward) which are common in daily routine. In these positions, after maxillary and mandibular arch scans three different interocclusal records will be taken. Also for assessment of these records in digital occlusal analysis module (oJMA, zebras), three different oJMA record will be taken. Researchers will compare neutral, forward and backward head positions to see if there are any difference in number, density and location of occlusal contacts.

Outcome Measures

Primary Outcomes (3)

• Number of Occlusal Contacts

  Evaluating the number of contacts in terms of point and area contact.

  Up to 24 weeks

• Density of Occlusal Contacts

  Evaluating the contact density by dividing the density in three groups (low, medium, and high).

  Up to 24 weeks

• Location of Occlusal Contacts

  Evaluating the location of contacts in "functional cusp," "central fossa," and "non-functional cusp." sections.

  Up to 24 weeks

Study Arms (3)

Neutral Head Position

OTHER

Neutral head position (PN), in which the head is positioned on the head-neck-spine plane.

Other: Digital Interocclusal Record In Different Head Positions

Forward Head Position

OTHER

Forward head position/active feeding position (PF), in which head is positioned 30° in front of head-neck-spine plane with forward head tilt.

Other: Digital Interocclusal Record In Different Head Positions

Backward Head Position

OTHER

Backward head position/drinking position (PB), in which the head is positioned 45° behind the head-neck-spine plane with backward head tilt.

Other: Digital Interocclusal Record In Different Head Positions
