Initial situation
- Severe space deficit
- Skeletal narrowing of the maxilla
- ENT-related problems
- Forced (compensatory) position of the mandible
The decision
The treatment plan used MARPE with screws to support molar distalization, combined with the Damon Q2 bracket system. This skeletal approach allowed correction of the space deficit without resorting to tooth extraction, which had been the standard approach for similar cases before MARPE became available.
Correction progressed quickly, and removal of the expansion appliance is planned as the case nears completion.
MARPE-assisted molar distalization can resolve a severe space deficit without extraction, where extraction was previously the standard solution.
The result
The space deficit was resolved through skeletal expansion and molar distalization rather than extraction, giving the patient an alternative treatment path. The case is progressing quickly, with removal of the expansion appliance planned as treatment nears completion.
Where a space deficit is skeletal in origin, MARPE combined with molar distalization can offer a non-extraction alternative that was previously unavailable.
About skeletal expansion & MARPE
This case demonstrates how skeletal narrowing of the maxilla, rather than dental crowding alone, can drive a severe space deficit. Diagnosing the skeletal component through transverse assessment is essential to selecting MARPE as a foundation for treatment. Combining skeletal expansion with molar distalization created space without extraction, illustrating how transverse diagnostics can reshape treatment planning and expand non-extraction options for cases that would once have required tooth removal.
Questions clinicians ask
Why was MARPE chosen instead of extraction for this space deficit?
The space deficit was linked to skeletal narrowing of the maxilla rather than dental crowding alone. MARPE combined with molar distalization created the needed space through skeletal correction, offering a non-extraction alternative.
How does molar distalization work alongside MARPE?
Skeletal anchorage from the MARPE screws supports distalizing the molars, which helps generate arch length as part of the overall space-gaining strategy.
Was ENT involvement relevant to this case?
The patient presented with ENT-related problems alongside the skeletal narrowing, which is consistent with how maxillary constriction can affect airway function in some patients.
