Also referred to as IPR, is a standard orthodontic approach used to create small amounts of space between teeth by precisely contouring a thin layer of enamel from the proximal surfaces of teeth. This procedure is often employed when there is mild crowding and 墨田区 前歯矯正 the goal is to avoid extracting teeth. With minimal proximal shaving, orthodontists can align them more evenly without affecting chewing or speech. The removal is confined to a negligible thickness, usually under half a millimeter per contact point, which is within clinically accepted thresholds. The minimally invasive nature of IPR helps maintain the structural integrity of the teeth while allowing for optimal positioning during orthodontic treatment. Interproximal reduction is especially useful in cases where the mandibular but the teeth are proportionally oversized.
