[Lateral teleradiographic diagnosis of deep bite]

Area of Science:

• Dentistry
• Radiology
• Orthodontics

Background:

• Assessing occlusal position from lateral teleradiographs is crucial for dental diagnostics.
• Close bite (malocclusion) presents diagnostic challenges in radiographic analysis.

Purpose of the Study:

• To determine if occlusal position can be reliably assessed using gnathometric and soft tissue data from lateral teleradiographs.
• To evaluate the diagnostic accuracy of lateral teleradiographs for identifying close bite.

Main Methods:

• Analysis of 113 lateral teleradiographs from students using A. M. Schwarz's X-ray analysis method.
• Comparison of measurements between anatomically correct occlusal positions and cases of close bite.
• Identification and quantification of seven specific close bite characteristics.

Main Results:

• A significant scatter in measurements was observed for anatomically correct occlusal positions.
• While only up to three close bite characteristics were identified in correct occlusions, four to six were present in close bite cases.
• The diagnosis of close bite was supported by the presence of four or more identified characteristics.

Conclusions:

• Lateral teleradiographs, when analyzed for specific characteristics, can reliably aid in the diagnosis of close bite.
• The presence of multiple close bite indicators in lateral teleradiographs confirms the diagnosis.
• This radiographic method offers a valuable tool for orthodontic assessment and treatment planning.
