Obesity in the United States is increasingly prevalent in adolescents. Metabolic and bariatric surgery is offered at select sites to adolescents (&lt;18 yr). Controversy exists regarding the safety of performing metabolic and bariatric surgery in adolescents.<br /><br /> The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program registry was employed to compare outcomes of adolescents with adults (18-40 yr) undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB).<br /><br /> Academic Teaching Institution.<br /><br /> The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program Participant User Files were reviewed for patients undergoing SG or RYGB (2015-2018). Patients were stratified by age and outcomes for adolescents versus adults compared. A bivariate analysis was performed on propensity-matched data.<br /><br /> After exclusion criteria were applied, 227,671 patients &lt;40 years remained, of whom 1005 were adolescents. For those undergoing RYGB (13.8% adolescents, 25.3% adults), demohan RYGB, and adolescent SG patients have similar outcomes and shorter operating room times compared with adolescent RYGB patients.The general boundaries to tooth movement are within the adjacent compact and trabecular bones, gingiva, mucosa, and muscular envelope. Findings from finite element analysis of maxillary posterior teeth distalization against mini-implants suggest that stiff outer and interproximal compact bone resists tooth movement, regardless of bone thickness, and that teeth should be steered away from this bone during orthodontic treatment. However, individual variation in the tooth-bone interface dictates the course and outcome of treatment, offering the basis for inferences on the limits of mini-implant anchorage and the presumed influence of the regional acceleratory phenomenon through decortication and microperforation, 2 modalities advocated to effect faster tooth movement.<br /><br /> Nasoalveolar molding (NAM) was introduced over 20years ago as adjunctive therapy for the correction of cleft lip and palate. In the current study, we propose a new approach using a digital workflow and 3-dimensional printing to fabricate clear aligner NAM devices.<br /><br /> A polyvinyl siloxane (PVS)impression of an infant with a unilateral complete cleft lip and palate (UCLP) is acquired and poured, and the stone model is scanned with an intraoral scanner. The stereolithography file is digitized, and the alveolar segments are digitally segmented and moved to the desired final position. The total distance moved is divided into a sequence of 1-1.5mm increments, creating a series of digital models. The models are 3-dimensionally printed along with button templates to allow free form positioning of the button on each model. A Vacuformmachine (Taglus, Mumbai, India) was used to fabricate a 0.040-in aligner for each stage.<br /><br /> We present 1 case that was treated successfully with this approach. Appointments for the NAM adjustments were primarily to monitor progress and counseling with less time spent adjusting the appliance. The appointment length was reduced by over 30minutes. Benefits of the aligner are improved fit, more precise increments of activation, reduced chairside time, and potentially minimized number of visits.<br /><br /> NAM custom aligners may provide similar benefits to the traditional approach while reducing the burden of care by reducing the number of visits and appointment duration. Further studies with a sample and longitudinal observations are needed to investigate the benefits of the proposed digital approach.<br /><br />NAM custom aligners may provide similar benefits to the traditional approach while reducing the burden of care by reducing the number of visits and appointment duration.

This research aimed to analyze the particulars of patients seeking retreatment and identify the causes of their original treatment failure.<br /><br /> An online questionnaire survey of adults seeking first-time orthodontic treatment (control) and retreatment (study) was conducted. Index of complexity, outcome, and need (ICON) scores were determined. Appraisal of treatment records was carried out to identify the causes of original treatment failure.<br /><br /> No significant differences were found between retreatment adult patients and first-timers regarding reasons for seeking orthodontic treatment, malocclusion type, self-perception of malocclusion, level of self-motivation, willingness for surgery, expectations of treatment improvement and duration. The predominant reason for seeking treatment in both groups was for aesthetic concerns. Retreatment patients presented with lower ICON scores (39.4; standard error, 0.26) than the first-time patients (54.3; sding reasons patients sought treatment. ICON was not a useful proxy of patient profiles. Poor treatment was the chief reason for the failure of the original treatment.

The treated group consisted of 15 patients who were evaluated at the pretreatment, posttreatment, and long-term posttreatment stages. The control group consisted of 15 subjects with normal occlusion, comparable to the experimental group at the long-term posttreatment period. Intergroup comparison of posttreatment changes was evaluated with t tests.<br /><br /> In the long-term posttreatment period, there was no significant change in the anteroposterior position of the maxilla and mandible to the cranial base. The lower anterior face height had a significantly smaller increase in the treated than in the control group. The maxillary molars in the treated group had significantly smaller vertical development, and the mandibular incisors had significantly greater labial tipping and protrusion than the control group.
