Intrusion of overerupted upper first molar using two orthodontic miniscrews. A case report

Area of Science:

• Dentistry
• Orthodontics
• Periodontology

Background:

• Loss of the mandibular first molar frequently causes opposing maxillary molar overeruption, leading to occlusal problems and bone loss.
• Traditional treatment often requires significant maxillary molar reduction or invasive surgery, potentially necessitating root canal therapy.

Observation:

• This case report details maxillary molar intrusion in a patient with dental anxiety and erosion due to gastric reflux.
• The patient presented with significant overeruption of the maxillary first molar.

Findings:

• Successful maxillary molar intrusion was achieved using two orthodontic miniscrews for skeletal anchorage.
• The procedure simplified treatment, eliminating the need for extensive surgery, headgear, or multi-unit anchorage.
• Significant intrusion occurred through the maxillary sinus cortical floor, preserving tooth vitality, root length, and periodontal health.

Implications:

• Orthodontic miniscrews offer a minimally invasive alternative for maxillary molar intrusion.
• This technique preserves valuable tooth structure and avoids costly restorative procedures.
• It provides a viable solution for managing occlusal discrepancies in patients with complex dental histories.
