Stability Following Combined Orthodontic-surgical Treatment for Skeletal Anterior Open Bite – a Cephalometric 15-Year Follow-up Study

Abstract

Treatment of skeletal open bite via Le Fort I and bilateral sagittal split osteotomy appears to be a clinically successful procedure providing stable results.

Stability of anterior open bite correction of adults treated with lingual appliances

“…About 12.5 per cent of patients experienced some relapse of the anterior OB and 2.5 per cent (1 out of 39 patients) had a negative OB at the follow-up examination. These results present higher stability than the results presented in the literature for surgical correction of AOpB (Bailey et al, 2004;Ding et al, 2007;Espeland et al, 2008;Stansbury et al, 2010;Teittinen et al, 2012) or conventional orthodontics with temporary anchorage devices (TADs) (Kuroda et al, 2007;Baek et al, 2010) and lower stability than the results presented for the crib appliance (Huang et al, 1990;Justus, 2001). By comparing the data of our sample to the data presented in a meta-analysis comparing stability of surgical versus non-surgical AOpB treatment (Greenlee et al, 2011), metaanalysis revealed the pre-treatment adjusted means of OB were −2.8 mm for the surgical and −2.5 mm for the nonsurgical groups.…”

“…For adult patients the main treatment approach for severe AOpB is often surgical. Stability was reported in about 75-85 per cent of the cases treated with different surgical procedures (Bailey et al, 2004;Ding et al, 2007;Espeland et al, 2008;Stansbury et al, 2010;Teittinen et al, 2012). Despite the relative stability of surgically corrected AOpB, orthodontic camouflage or conventional orthodontic treatment is usually preferred by the patients due to reduced risks.…”

Combined Treatment of Open Bite – Long-term Evaluation and Relapse Factors

“…Das Zusammenspiel der verschieden dentalen, skelettalen und Weichteil-Faktoren bei der Rezidiventstehung wird in den Arbeiten von Ding et al [6] und Lo & Shapiro [24] betont. In der vorliegenden Untersuchung war es möglich, diese Parameter genauer zu eruieren und ihren Einfluss zu werten.…”

“…Only Ding et al [6] mention the pre-operative orthodontic therapy as one reason for relapse. But changes caused by the orthodontist (dental compensation or decompensation of the skeletal deviations) are key to making surgical repositioning possible.…”

The Factors Affecting Long-Term Stability in Anterior Open-Bite Correction - A Systematic Review

“…They include severity of AOB malocclusion prior to treatment, extractions of premolars, correction of open-bite with or without orthognathic surgery, or different methods of retention (4,5). Recently, many studies have been conducted to check the long-term stability of corrected AOB malocclusion (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24). When we searched the literature, we came across two systematic reviews of case series studies conducted to assess the effectiveness of orthodontic and orthopedic treatment in AOB correction (4,5).…”
