Summary
Condylar displacements during dental preparations are linked to specific tooth involvement. Including the second premolar initiates displacements, with further increases observed when the first premolar and canine are also prepared.
Area of Science:
- Dental anatomy and biomechanics
- Maxillofacial surgery and orthodontics
Context:
- Dental preparations can alter the position of the mandibular condyle.
- Understanding condylar displacement is crucial for treatment planning.
Purpose:
- To investigate condylar displacements resulting from dental preparations.
- To determine the influence of specific teeth on condylar movement.
Summary:
- Condylar displacements were observed in preparations involving the second premolar.
- Displacements were ventrocranial, increasing with the inclusion of the first premolar and canine.
- Maximum observed displacements reached up to 2.8 mm cranially and 2.8 mm ventrally.
Impact:
- Findings highlight the importance of considering condylar position during dental procedures.
- Informs surgical and orthodontic approaches to minimize adverse effects on the temporomandibular joint.
- Provides quantitative data on potential condylar displacement magnitudes.
