Patients presenting complaint: Prominent canine tooth on the right side
- Posterior crossbite on the right side.
- Severe crowding with crossbite on the upper right 2.
- Upper arch is constricted
- Square shaped arches
- Good, thick, gingival coverage in posteriors.
Overview of case: The arch shape is the key to solving the case. By expanding the upper arch and combining with max ipr, we can avoid the need for extractions.
We used an “optimised rotation attachment” on the ur3. As the molar relationship was stable and free from interference.
We left them as they were and only moved 5 to 5.
