What does “Interproximal reduction” mean?
Interproximal reduction removes a limited amount of enamel from the contact surfaces between teeth to adjust tooth width or create space needed for orthodontic treatment and related purposes.
Original spelling: IPR
A method different from extracting the entire tooth
Only the necessary amount is removed from the sides of adjacent teeth to gain space or adjust the relationship between tooth widths. This differs from extraction in both the tissue removed and the amount of space available. Interproximal reduction cannot replace extraction in every case requiring substantial space.
Planning the surfaces and amount to be reduced
Determine the area and scope of application by checking the shape of the tooth, enamel, cavity, restoration status, and required space. Allows the surface to be smoothed and cleaned after removal. Reduced enamel does not grow back, so it is not a treatment to be performed randomly.
Post-treatment care
Temporary sensitivity may occur and should be monitored. The surfaces are appropriately polished, with fluoride use and good oral hygiene maintained. Interproximal reduction does not inevitably cause decay, but the existing decay risk and oral hygiene remain important.
Frequently Asked Questions
Does interdental preparation inevitably weaken teeth?
Interproximal preparation performed to an appropriate extent does not necessarily weaken the teeth. The area and amount are selected and the surface is polished to leave enamel to protect the tooth. Removed enamel does not grow back, so you should check the condition of your teeth and avoid excessive preparation.
Can I avoid tooth extraction by performing interproximal preparation?
Can be used to gain a small amount of space, but will not solve all space shortages. Compare with other methods depending on the required movement and tooth and jaw conditions.
