Brief Summary

This study compares two methods used to measure how teeth come together (occlusal contacts) in patients who have natural teeth (dentate patients). The first method uses a modern jaw tracking device, while the second relies on the conventional mounting technique. The goal is to determine which method is more accurate for diagnosing bite alignment and contact points. This is a diagnostic test accuracy study, meaning it focuses on evaluating how well each technique performs in identifying the correct occlusal contacts.

Conditions

Jaw Tracking

Keywords

Diagnostic Mounting; Jaw Tracking Device; Conventional Mounting Technique; Occlusal Contact Points

Outcome Measures

Primary Outcomes (1)

• Accuracy of occlusal contact point detection as measured by comparing the contact points obtained from each mounting technique (jaw tracking device vs. conventional mounting) with the clinical intraoral occlusal contacts observed using articulating paper

  3 months

Study Arms (1)

Conventional Mounting Technique

EXPERIMENTAL

Device: Jaw Tracking Device

Interventions

Jaw Tracking Device DEVICE

A jaw tracking device is a digital tool that records real-time jaw movements to accurately analyze occlusion and assist in virtual model mounting.

Conventional Mounting Technique
