Background
Overeruption of an upper molar following loss of the opposing tooth is a common clinical finding. Rehabilitation can be difficult when the interocclusal space is reduced.


Aim
To intrude an overerupted upper first molar and replace the missing lower first molar.


Methods
Buccal and palatal microscrews and a transpalatal bar were placed. The palatal miniscrew loosened shortly after implantation and was not replaced. A short length of elastomeric chain from the buccal miniscrew applied 30 g of force to the overerupted molar. The elastomeric chain was replaced every four weeks.


Results
Sufficient intrusion of the upper molar was obtained in 4 months.


Conclusion
A single buccal microscrew and transpalatal arch can be used to intrude an overerupted upper molar.
