Anterior openbite malocclusion in adults:

Abstract

Objectives To investigate stability and satisfaction in adult anterior open bite (AOB) patients at least 9 months post-treatment, as well as patient and practitioner factors that may be associated with stability and satisfaction. Materials and Methods Practitioners and their adult AOB patients were recruited through the National Dental Practice-Based Research Network. Data on patient and practitioner characteristics, treatment recommendations and factors were previously collected. Treatment stability was determined by assessing post-treatment intraoral photographs. Patient satisfaction was determined from post-treatment questionnaires. Treatment was categorized into aligners, fixed appliances, temporary anchorage devices, and orthognathic surgery. Extractions were also investigated. Retention type was categorized into vacuum-formed, Hawley-style, or bonded retainers, and regimens were classified as full-time or part-time wear. Results Retention data collected from 112 patients had a mean post-treatment time of 1.21 years. There were no statistically significant differences in stability between treatment groups. Depending on whether a qualitative index or a millimetric measure was employed, stability ranged from 65% to 89%. Extractions and less initial lower incisor proclination were associated with higher stability in patients treated with fixed appliances only. High satisfaction was reported by patients at retention. There were no clear differences in stability or satisfaction among retention types or regimens. Conclusions The stability of adult AOB orthodontic treatment was high, regardless of treatment or retainer modality. Satisfaction in adult AOB patients was high, regardless of retention type or regimen.

“…The potential of our profession to learn more about the outcomes of our care and propose evolving best practices is vast from ‘Big Mouth’ data and from studies in the National Dental Practice‐Based Research Network (NDPBRN). Several key findings stemmed from one NDPBRN study on the most effective methods to address anterior open bites 13–15 .

Treatment of Open Bite Based on Skeletal Anchorage Using Extrusion Lever Arms and Class III Elastics

“…Open bite is defined as the absence of occlusal contact in the vertical direction between the teeth of the opposing dental arches at the maximum intercuspation [ 1 , 2 ]. The lack of occlusal contact can be located in the anterior or posterior region of dental arches, caused by numerous external, environmental, anatomic, and genetic factors [ 3 ].…”

Nonsurgical Orthodontic Treatment of a Severe Open Bite Case Using Miniscrews with Modified Multiloop Edgewise Arch Wire Technique

“…Anterior open bite (AOB) is defined as a condition in which there is no contact and no vertical overlap of the lower incisor crown with the upper incisor crown when the mandible is in full occlusion [ 1 ]. In an adult Caucasian American population, the prevalence of AOB was reported to be around 3%; however, it can range anywhere from 1.5 to 11 percent depending on the ethnic group and dental age [ 2 ].…”
