The quadrilateral analysis: an individualized skeletal assessment.

Area of Science:

• Orthodontics and Oral and Maxillofacial Surgery
• Diagnostic Imaging and Cephalometrics

Background:

• Current orthodontic diagnostic methods, particularly cephalometric analyses, often fail to accurately detect and locate skeletal dysplasias.
• This diagnostic limitation can lead to surgical interventions that mask underlying skeletal defects rather than correct them, compromising facial balance.

Observation:

• Existing cephalometric analyses do not fully assess the extent or precise location of skeletal dysplasias within the jaws.
• Surgeons often rely on cephalometric norms or visual assessment, which may not address the root cause of the skeletal issue.

Findings:

• The quadrilateral analysis offers an individualized cephalometric diagnosis for patients with or without skeletal dysplasias.
• This method reliably assesses the need for orthodontic treatment, surgical intervention, or a combination of both.

Implications:

• Accurate diagnosis via quadrilateral analysis can guide appropriate treatment planning, ensuring corrections address the actual skeletal problem.
• This approach aims to restore normal facial bone balance, moving beyond masking defects to achieving satisfactory functional and aesthetic outcomes.
