Stability of Mandibular Irregularity Index With and Without PAOO: A Review
نویسندگان
چکیده
Long-term stability after orthodontic treatment is highly desirable, especially alignment of the mandibular anterior dentition as might be quantified by the irregularity index. Post orthodontic treatment stability is a vexing problem, and without permanent fixed retention, this issue has been a problem without a solution until recently. In 2014, long term stability of the mandibular anterior segment was shown to be affected by alveolar corticotomy and augmentation bone grafting (PAOO) [1].

Mandibular irregularity index stability following alveolar corticotomy and grafting: a 10-year preliminary study.
OBJECTIVE To evaluate mandibular irregularity index stability following orthodontic treatment facilitated by alveolar corticotomy and augmentation bone grafting (Cort+). MATERIALS AND METHODS The irregularity index of 121 orthodontically treated and 15 untreated patient study casts was analyzed at 5 years and 10 years. RESULTS Cort+ resulted in significantly lower mandibular irregularity in...
متن کاملStability of Rapid Maxillary Expansion
The stability of rapid maxillary expansion (RME) was studied in 20 patients. Study models were evaluated immediately prior to treatment, at the end of treatment, and at least 4 years post-treatment with regards to maxillary and mandibular intermolar widths, intercanine widths, arch perimeters, and irregularity indices. The mean maxillary intermolar width increased by 3.7 mm during treatment, an...

متن کاملTreatment of Adults with Anterior Mandibular Teeth Crowding: Reliability of Little's Irregularity Index
The attempt of this article was to assess reliability of Little's Irregularity Index (LII) as for stability of the treatment outcomes in adults with crowded mandibular incisors. LII was measured on a digital cast prior to an orthodontic treatment (T1) of the 302 patients thus allowing us to establish the treatment plan, which called for (a) expansion (group 1), interproximal stripping (group 2)...

The purpose of this study involving a sample of children with single central incisor crossbite was to determine the relationship between clinical crown lengths of the crossbite and noncrossbite mandibular incisors, incisor irregularity, and orthodontic correction of the crossbite. In addition, for comparison, the normal maturational change in position of the labial gingival margin of mandibular...
