Initial situation
- Severe deep bite
- Pronounced crowding in the mandible
- Moderate crowding in the maxilla
- Maxillary arch constriction
- Crossbite involving the second molars
The decision
A fast and effective non-extraction treatment was carried out using the Damon bracket system, with a total treatment time of 20 to 24 months.
Long-term follow-up, not just the immediate post-treatment result, is what confirms the true stability of deep bite and crossbite correction.
The result
Treatment achieved a highly esthetic, functionally correct, and stable outcome. The patient remains under long-term follow-up, with a retention period of 8 years to date.
Severe deep bite and crossbite cases can be resolved without extraction using a fixed appliance system, with stability confirmed by extended, multi-year retention follow-up.
About skeletal expansion & MARPE
A severe deep bite combined with maxillary arch constriction and second-molar crossbite reflects both a vertical and a transverse dimension to the malocclusion, which need to be addressed together rather than in isolation. In cases like this, clinicians typically evaluate whether a non-extraction, fixed appliance approach can resolve both dimensions efficiently without sacrificing stability. Extended retention follow-up, well beyond the standard post-treatment window, remains the most reliable way to confirm that a non-extraction plan for this kind of combined presentation has truly held.
Questions clinicians ask
What was the initial diagnosis in this case?
The patient had a severe deep bite, pronounced mandibular crowding, moderate maxillary crowding, maxillary arch constriction, and crossbite of the second molars.
Was extraction required to treat this case?
No; a fast, non-extraction approach was used with the Damon bracket system over a total treatment time of 20 to 24 months.
How long has the result remained stable?
The patient remains under long-term follow-up, with a retention period of 8 years to date and continued monitoring planned.
