“…11 In our sample, extractions were typically reserved for AOB patients with severe crowding and increased mandibular incisor proclination. 19 In these cases, it is possible that the extraction spaces were primarily used to resolve crowding and reduce incisor proclination, and the "drawbridge" effect may not have been fully realized. Details of treatment mechanics and stability related to extractions will be explored in future studies.…”

Introduction: Anterior openbite (AOB) continues to be a challenging malocclusion for orthodontists to treat and retain long-term. There are many orthodontic treatment modalities used to treat AOB in adult patients, but there is no consensus on which modalities are most successful. This study aims to identify the overall success rate of AOB orthodontic treatment in the adult population across the United States, as well as factors that influence treatment success. Methods: Practitioners and their adult AOB patients were recruited through the National Dental PBRN. Patient dentofacial and demographic characteristics, practitioner demographic and practice characteristics, and factors relating to orthodontic treatment were reported. Treatment success was determined from post-treatment lateral cephalometric films and intraoral frontal photos. Treatment was categorized into four main groups: aligners, fixed appliances, TADs and orthognathic surgery. Extractions were also evaluated. Univariate and multivariate models were used to evaluate how treatment success varies with treatment modality, pre-treatment dentofacial characteristics, and patient and practitioner demographic and practice characteristics. Results: End of active treatment data was collected from 84 practitioners and 254 patients. Eighty four percent of patients finished with positive vertical overlap of all incisors and 93% with positive overbite on the post-treatment lateral cephalogram. While there were no statistically significant differences in success rates between the treatment groups, patients treated with orthognathic surgery had an increased odds for success when compared to those treated with fixed appliances only. Treatment success was also associated with academic practice setting, pre-treatment IMPA £90°, no to mild pre-treatment crowding, and treatment duration < 30 months. Conclusion: The success of orthodontic treatment in adult AOB patients who participated in this study was very high. While there was a range of success for the major treatment modalities, orthognathic surgery was the only treatment modality that reached statistically significance. There were some pre-treatment dentofacial characteristics and treatment factors associated with successful closure of AOB. I would like thank the University of Washington Department of Orthodontics and the University of Washington Orthodontic Alumni Association for this wonderful opportunity and academically fulfilling experience. Thank you to my research committee members, Greg Huang, Geoffrey Greenlee, and Andrea Burke, for your mentorship and guidance. I would also like to give a special thank you to my research partner, Sam Finkleman. Finally, I would like to express my gratitude and appreciation for my family and friends for all their support.

“…Despite a recommendation rate of 37% for orthognathic surgery, only 21% of patients who completed treatment had surgery. 19 Only 8% of the patients were treated with TADs. Treatment was classified into four mutually exclusive groups, previously described, for further analysis.…”

“…doi:10.2209/tdcpublication. Treatment in patients with anterior open bite and incisor proclination usually involves extraction of the premolars with the aim of improving maxillary protrusion and crowding 3) . Moreover, the incisors have to be moved considerably to achieve normal occlusion, which leads to the risk of severe root resorption.…”

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.
