Impact of orthodontic decompensation on bone insertion

Area of Science:

• Dentistry
• Orthodontics
• Periodontology

Background:

• Assessing the biological costs of orthodontic tooth movement on the periodontium and tooth roots is crucial.
• Cone-beam computed tomography (CBCT) offers advanced capabilities for evaluating tooth and bone morphology.
• Understanding these relationships is vital for optimizing orthodontic treatment outcomes.

Purpose of the Study:

• To present a case report on the use of CBCT in evaluating bone morphology during orthodontic treatment.
• To analyze the qualitative and quantitative changes in bone plates and tooth root levels.
• To reflect on treatment protocols for patients with dentoskeletal discrepancies.

Main Methods:

• Case report of a 20-year-old male patient with Class III malocclusion and a hyperdivergent facial pattern.
• Surgical and orthodontic treatment, including significant labial movement of mandibular incisors.
• Utilized Cone-beam computed tomography (CBCT) for pre- and post-treatment evaluation of buccal and lingual bone plates.

Main Results:

• CBCT enabled detailed assessment of bone morphology and tooth movement.
• Significant changes in the bone insertion level of maxillary and mandibular incisors were observed.
• The study highlights the impact of orthodontic decompensation on alveolar bone.

Conclusions:

• CBCT is a valuable tool for evaluating the biological consequences of orthodontic tooth movement.
• Treatment protocols for dentoskeletal discrepancies should consider potential effects on periodontal support.
• Further research is needed to refine treatment strategies for minimizing biological costs.
