The Irregularity Index: A quantitative score of mandibular anterior alignment

摘要: A quantitative method of assessing mandibular anterior irregularity is proposed. The technique involves measurement directly from the cast with a caliper (calibrated to at least tenths millimeter) held parallel occlusal plane. linear displacement adjacent anatomic contact points incisors determined, sum five measurements representing Irregularity Index value case. Reliability and validity were tested, favorable results. At University Washington, several clinical studies have been are continuing be performed, using this as one methods pretreatment status posttreatment change. It hoped that article will aid reader in understanding rationale utility simple tool which could used malocclusion assessment.
