Julldent Dentofacial Analyser

• Occlusal Plane Registration: The system can accurately register and record the patient’s occlusal plane, which represents the horizontal alignment of the upper and lower teeth during closure.
• Three-Plane Tilt Registration: It can capture tilts and inclinations in the occlusal plane in three dimensions. This means it records not only the horizontal orientation but also any tilting or angulations in different directions.
• Articulator Compatibility: The system is designed to interface seamlessly with an articulator, a device used for simulating the patient’s jaw movements. This compatibility allows for precise model articulation and diagnostic accuracy.
• Reference to Average 100 mm Axis-Incisal Distance: The system uses an average 100 mm axis-incisal distance as a reference point. This standardized measurement ensures consistency and reliability in the registration process.
• O-Ring Adjustments: It features O-rings that can be adjusted on the Vertical Indicator Rod. These adjustments allow for customization to fit the patient’s unique facial landmarks accurately.
• Facial Proportion Assessment: By adjusting the O-rings on the Vertical Indicator Rod, the system enables the evaluation of facial proportions, aiding in the assessment of how different facial features relate to each other.
• Lip Commissure Height Measurement: The Index Tray is equipped for measuring the height of the lip commissures, important for marking on study casts and understanding lip posture.
• Comprehensive Diagnosis: The system’s ability to capture occlusal plane data, tilts, and facial proportions contributes to a comprehensive diagnosis of the patient’s condition, which is crucial for effective treatment planning.
• Customization: The system allows for customization to ensure a precise fit to the patient’s facial landmarks, enhancing the accuracy of measurements and analysis.
• Diagnostic Reports: It facilitates the generation of detailed diagnostic reports summarizing the findings, measurements, and assessment of the patient’s craniofacial and occlusal characteristics.
• Orthodontic and Oral Surgery Aid: The DFA system is an invaluable tool for orthodontic and oral surgery practices, providing critical data for treatment planning and improving diagnostic accuracy.
• Facial Landmark Evaluation: The system assists in the evaluation of facial landmarks, helping clinicians understand how these features contribute to overall facial aesthetics and function.

• Jull-Dent 133 Dentofacial Analyser Comparison of the Dento-Facial Analyzer System with an earbow for mounting a maxillary cast.

Statement of problem

• The Dento-Facial Analyzer System (DFA) is used by clinicians to mount maxillary casts and evaluate and treat patients.

Purpose

• The purpose of this study was to evaluate maxillary casts mounted using the DFA with casts mounted using the Pana-Mount Facebow (PMF). Both articulation methods were compared against a lateral cephalometric radiograph.

Material and methods

• Fifteen dried human skulls were used. Lateral cephalometric radiographs and 2 maxillary impressions were made of each skull. One cast from each skull was mounted on an articulator by means of the DFA and the other by using the PMF.  A standardized photograph of each articulation was made, and the distance from the articular center to the incisal edge position and the occlusal plane angle was measured.  The distance from the condylar center to the incisal edge and the occlusal plane angle was measured from cephalometric radiographs. Finally, the 3-dimensional position of each articulation was determined with a SEMI-AUTOMATIC ARTICULATOR. A randomized complete block design analysis of variance (RCBD) and post hoc tests (Tukey-Kramer HSD) (a-.05) were used to evaluate the occlusal plane angle and axis-central incisor distance. A paired 2-sample t-test for means (a=.05) was used to compare the X, Y, and Z distance at the right and left condyle.

Results

• The DFA and PMF mounted the maxillary cast in a position that was not statistically different from the skull when comparing the occlusal plane angle (P=.165).  Both the DFA and the PMF located the maxillary central incisor edge position in a significantly different position compared with the skull (P=.OOI) but were not significantly different from each other. The 3-dimensional location of the maxillary casts varied at the condyles by approximately 9 to 10.3 mm.

Conclusion

• The DFA mounted the maxillary cast in a that was not statistically different from the PMF when comparing the incisal edge position and the occlusal plane angle. Both the DFA and the PMF located the maxillary incisal edge position in a significantly different position compared with the anatomic position on dried human skulls.

• Dentofacial Analysers (DFA) are compatible with all Semi Adjustable Articulators (corident, Sam, etc.)
