Computer aided gnathosonic analysis: distinguishing between single and multiple tooth impact sounds

Area of Science:

• Dentistry
• Biomedical Engineering
• Acoustics

Background:

• Watt's classification distinguished tooth contact sounds based on simultaneity and reproducibility.
• Large occlusal prematurities, like high restorations, produce short, sharp, reproducible sounds, complicating classification.
• Distinguishing single from multiple tooth contacts is crucial for diagnosing occlusal issues.

Purpose of the Study:

• To develop and describe a method for differentiating single from multiple tooth contact sounds.
• To analyze the acoustic properties of tooth contacts, particularly in the presence of occlusal prematurities.
• To improve the understanding of sound-based diagnostics in dentistry.

Main Methods:

• Utilized sound analysis via headphones placed over the ears.
• Analyzed the phase and amplitude characteristics of detected tooth contact sounds.
• Applied the method to distinguish between single and multiple tooth contact events.

Main Results:

• Successfully developed a method to differentiate single from multiple tooth contact sounds.
• The analysis of sound phase and amplitude proved effective in distinguishing contact types.
• Findings suggest acoustic analysis can identify complex occlusal conditions.

Conclusions:

• Acoustic analysis of tooth contact sounds offers a viable method for distinguishing single from multiple contacts.
• This technique can aid in the detection and characterization of occlusal prematurities.
• Further research can refine this method for clinical dental applications.
