Surgical intervention to reestablish adequate intermaxillary space before fixed or removable prosthodontics
Journal of the American Dental Association (1939)
|November 1, 1977
Summary
Supraeruption of maxillary molars caused significant loss of intermaxillary space. A posterior segmental osteotomy successfully repositioned the affected segment, restoring crucial space for the patient.
Area of Science:
- Oral and Maxillofacial Surgery
- Orthodontics
- Periodontics
Background:
- Loss of intermaxillary space can result from supraeruption of maxillary molars and alveolar ridge drop.
- This condition complicates orthodontic treatment and restorative procedures.
Observation:
- A patient presented with supraeruption of right maxillary molars and a dropped alveolar ridge, leading to a significant reduction in intermaxillary space.
- The supraerupted segment extended into the maxillary sinus.
Findings:
- A posterior segmental osteotomy was performed under local anesthesia and intravenous sedation on an outpatient basis.
- The osteotomized segment was repositioned superiorly into the maxillary sinus.
- Stabilization was achieved using a prefabricated acrylic splint.
Implications:
- This surgical approach effectively restored the lost intermaxillary space.
- The patient experienced normal postoperative healing and a quick return to daily activities.
- This technique offers a viable solution for managing severe molar supraeruption and associated intermaxillary space loss.
