“…This TB sample was previously used in other studies to investigate the TB therapy effects;6 25 untreated class II subjects (12 girls and 13 boys; 11.9±1.9 years) obtained from the University of Michigan growth study and matched with the experimental groups for skeletal age (at the start or during the growth spurt), sex, and craniofacial morphology. This study was approved by the State University of New York at Buffalo Institutional Review Board.…”

“…One of the unique features of this appliance is that it is constructed in two separate parts: the upper and lower appliances. Forward mandibular posturing is achieved by incorporating buccal blocks with interlocking inclined planes of approximately 70°, with the lower blocks engaging in front of the upper blocks 4–6…”

ObjectivesWe evaluated the skeletal and dentoalveolar effects of the Forsus Fatigue Resistance Device (FRD) and the Twin Block appliance (TB) in comparison with nontreated controls in the treatment of patients with class II division 1 malocclusion.Materials and methodsThis retrospective study included three groups: TB (n=37; mean age, 11.2 years), FRD (n=30; mean age, 12.9 years), and controls (n=25; mean age, 12.6 years). Lateral cephalograms were evaluated at T1 (pretreatment) and at T2 (postappliance removal/equivalent time frame in controls). Cephalometric changes were evaluated using the Clark analysis, including 27 measurements.ResultsSagittal correction of class II malocclusion appeared to be mainly achieved by dentoalveolar changes in the FRD group. The TB was able to induce both skeletal and dentoalveolar changes. A favorable influence on facial convexity was achieved by both groups. Significant upper incisor retroclination occurred with the TB (−12.42°), whereas only −4° was observed in the FRD group. The lower incisors proclined more in the FRD group than the TB group. Incisor overjet reduction was 62% in the TB group versus 56% in the FRD group. Molar relation was corrected in both functional groups, resulting in a class I relation, although no change appeared in the control sample.ConclusionBoth appliances were effective in correcting the class II malocclusion. Both the FRD and the TB induced significant maxillary and mandibular dentoalveolar changes; skeletal changes were induced by TB but not FRD therapy.

“…The aspiration or ingestion of orthodontic appliances is less common but not less varied in the types of appliance involved. These include swallowing an expansion appliance key [5], a transpalatal arch [6], a lower spring retainer [7], a fragment of a maxillary removable appliance [8], and a piece of archwire [1]. A rare case of accidental swallowing of a removable quad helix by a 13-year-old boy affected by Down's syndrome, which necessitated surgical removal, has also been reported [9].…”

Ingestion of a broken part of fixed orthodontic appliance is a potential complication during orthodontic treatment. We report a case of accidental ingestion of molar band and its subsequent diagnosis followed by endoscopic retrieval method. Although prevention of such incidence is the best method at the same time management of such an event is also crucial. The objective of this paper is to draw attention to the potentially serious complications that can occur if preventive techniques are not practiced and also the management of such event.
