Goal-oriented positioning of upper second molars using the palatal intrusion technique
1Orthodontic Department, University Dental School, Graz, Austria.
Summary
This orthodontic technique uses a modified transpalatal arch to intrude the palatal cusp of upper second molars. It effectively corrects buccal crossbites and reduces molar prominence with controlled root torque.
Area of Science:
- Orthodontics
- Dental Mechanics
Background:
- Buccal crossbites in the molar area are common orthodontic issues.
- Prominence of the palatal cusp of the upper second molar can complicate treatment.
Purpose of the Study:
- To describe a novel orthodontic mechanical variation.
- To reduce palatal cusp prominence of upper second molars.
- To correct molar area buccal crossbites.
Main Methods:
- Utilizing a modified transpalatal arch with a soldered spur.
- Bonding a button to the palatal surface of the second molar.
- Employing elastic chain for palatal cusp intrusion.
- Controlling buccal root torque during intrusion.
Main Results:
- Successful reduction of palatal cusp prominence.
- Effective correction of buccal crossbites in the molar region.
- Demonstrated control of buccal root torque.
Conclusions:
- The described palatal intrusion technique is simple and highly efficient.
- This method offers a reliable approach for correcting upper second molar position.
