Photographic Openbite Severity Index was used to assess treatment success and stability. Skeletal, dental, and soft tissue treatment outcomes were evaluated using cephalometric analysis.Results: Pretreatment and posttreatment records were collected for 115 patients. Thirty-three were treated with extractions; 82 were treated without extractions. The EXT group was younger, more crowded, and had less previous orthodontic treatment. Success rate of AOB correction in the EXT group was slightly higher (97%) than the NE group (92%) but not statistically different. No significant differences were observed in skeletal outcomes. The EXT group exhibited more lingual tipping and posterior movement of maxillary and mandibular incisors and less extrusion of mandibular incisors. Dental changes in the EXT group were associated with increased nasolabial angle and lip retraction. The small number of patients with AOB relapse did not provide enough power to identify differences in stability between the two groups.Conclusions: Orthodontists have high success correcting AOB with or without extractions. The EXT group displayed more retraction and lingual tipping of incisors as well as increased retraction of soft tissues. Stability of AOB closure was more than 90% for both groups after 1 year, with marginal increases in stability after extractions.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":"149-156"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11842112/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143070581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Experiment 1, the force system of a three-bracket geometry was compared with two adjacent two-bracket geometries. In Experiment 2, 36 three-bracket geometries were tested when straight wires of varying materials were engaged.Results: Experiment 1 results showed that the force system of a three-bracket geometry could be simplified into two adjacent two-bracket geometries. Experiment 2 results showed that the impact of the third bracket (Bracket C) affected the force system of the adjacent bracket only (Bracket B), with Bracket C having no statistically significant effect on the force systems at Bracket A. A distinct pattern of forces and moments was found in each of the 36 three-bracket geometries.Conclusions: In this study, we experimentally validated the hypothesis of Burstone and Koenig, showing that a three-bracket geometry can be simplified into two adjacent two-bracket geometries. The force system of 36 three-bracket geometries was determined, assisting clinicians with better anticipating previously unpredicted and undesirable movements, thereby improving treatment efficiency.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143485212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CBCT-generated lateral cephalograms were analyzed for skeletal and dental changes. Width changes in the five circummaxillary sutures (frontomaxillary, pterygomaxillary, zygomaticofrontal, zygomaticomaxillary, and zygomaticotemporal) were measured before and after MAMP. Suture widths were measured using ImageJ software on CBCT images. The pre- and post-MAMP mean values of the bilateral width changes were compared. The magnitude of the width changes of the five circummaxillary sutures were ranked to identify the most substantially altered sutures. Statistical significance was determined using the Friedman test.Results: In the CBCT-generated lateral cephalometric analysis, statistically significant increases were observed in SNA and ANB values, with the most pronounced results seen in overjet (P < 0.05). After MAMP, all five circummaxillary sutures demonstrated a statistically significant increase in width. The zygomaticofrontal, pterygomaxillary, and zygomaticotemporal sutures exhibited significant changes, with the zygomaticofrontal suture showing the greatest increase in width.Conclusions: Among patients with Class III malocclusion treated with MAMP, the most pronounced width increase was observed in the zygomaticofrontal suture, whereas the frontomaxillary suture exhibited the least change.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143461122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The average Hausdorff distance was calculated to assess the difference between automatic and manual segmentations. Tooth position and angulation, including rotation, tip, and torque, of bilateral upper first molars and central incisors were obtained to measure the clinical error of automatic superimposition. Reliability was calculated by intraclass correlation coefficient (ICC).Results: The average Hausdorff distance was 0.36 mm between automatic and manual segmentations of the palatal stable region and was larger than the intraexaminer and interexaminer deviations. The tooth position deviation was <0.32 mm, and the tooth angulation difference was <0.26° for tip and torque, and 0.46-0.61° in rotation. ICCs, used for assessment of reliability, ranged from 0.82 to 0.99 in all variables.Conclusions: The GCN-based MDM superimposition is an efficient method for the assessment of tooth movement in adults. The clinical error in tooth position and angulation induced by the method was clinically acceptable. Reliability was as high as manual segmentation.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143443070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acceptance of 18 orthodontic risks was investigated with a structured questionnaire. Personality traits of included patients were assessed with a validated Chinese version of the Big Five Inventory. Statistical analyses were performed as appropriate, and potential correlations were identified using multivariate binary logistic regression analysis.Results: Acceptability of the investigated orthodontic risks ranged from 47.1% to 87.0%, with periodontitis being the least accepted. Length of treatment (P = .015) and relapse (P = .007) were more unacceptable to older patients. Female participants showed less tolerance to periodontitis (P = .017) than male counterparts. Among the five dimensions of personality traits, conscientiousness was significantly associated with acceptance of tooth extraction and associated risks (odds ratio [OR] = 1.131, P = .002), problems eating (OR = 1.182, P < .001), problems speaking (OR = 1.111, P = .022), and appliance breakage (OR = 1.109, P = .008), while openness was a significant predictor to the acceptance of length of treatment (OR = 1.090, P = .044).Conclusions: Among patients seeking orthodontic treatment, periodontitis was the least accepted risk.

The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) and the esthetic component of the Index of Orthodontic Treatment Need (IOTN-AC) were used to evaluate students' psychosocial impact of dental esthetics and severity of malocclusion, whereas the rationale for postponing the initiation of orthodontic treatment was recorded through an open-ended question, analyzed using thematic content analysis.Results: In total, 270 students, 55.2% female, participated. The single statistically significant factor predicting willingness to uptake orthodontic treatment was the PIDAQ-Psychological Impact subscale (OR: 1.24; 95% CI: 1.11-1.37, P < .001). Gender and age were not associated with willingness to pursue treatment. Seven main themes emerged regarding reasons for postponement: fear of the procedure, embarrassment regarding appearance during treatment, low prioritization of esthetics, insufficient information, high cost of treatment, prolonged duration of treatment, and residential mobility.Conclusions: The findings suggest that psychological impact of dental esthetics constitutes the main driver to pursue orthodontic treatment. A patient-centered orthodontic approach should address the possible barriers to its initiation. Increasing young adults' oral health literacy could be key in empowering them to make better informed decisions regarding their oral health-related quality of life.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143416600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The NET3-corrector consisted of a hybrid-expander, a lower lingual arch, and a modified PowerScope spring. The RME-FM group received an RME-facemask combination. T2 records were collected when an overjet of at least 2 mm was achieved. Differences between two timepoints within groups and differences between groups were tested using paired samples t-test and independent samples t-test, respectively (P < .05 was considered statistically significant).Results: The treatment time was 10.5 months with NET3-corrector and 12 months with RME-FM. The NET3-corrector was well tolerated by patients and the Class III malocclusion was corrected in all patients in both groups. The overall maxillary skeletal change was greater with the NET3-corrector, with an additional 2° advancement at SNA (P < .001). Significant differences in maxillary incisor angulation were observed in the RME-FM group in comparison to NET3 (-0.37 ± 3.31 vs 4.96 ± 3.80; P < .001).

Treatment duration from surgical exposure until the canine appeared in the oral cavity and until achieving ideal alignment were recorded in months.Results: Average treatment duration until appearance in the mouth was 14.61 ± 9.28 months and 26.98 ± 12.44 months until ideal alignment. Buccally impacted canines emerged in 6.56 ± 3.24 months and were ideally aligned in 19.44 ± 8.49 months in comparison with palatally positioned at 16.34 ± 9.19 and 28.91 ± 12.77 months, respectively. Canines localized around lateral incisors had shorter treatment times than those localized around central incisors. Canines that were inclined >30° to the sagittal medial line (SML) had significantly longer treatment time until initial appearance in the mouth (16.31 ± 9.32) compared with those inclined less (10.82 ± 8.92). Linear regression analyses demonstrated that these factors were predictors for both treatment duration until emergence and ideal alignment of the canine.Conclusions: Treatment duration for IMCs is lengthy, particularly for palatally and mesially positioned canines and those with greater inclinations. Palatally located canines typically require twice as much time to emerge as those positioned buccally. Canines located nearer the central incisor area take twice as much time to emerge as those located in the lateral incisor area.","PeriodicalId":94224,"journal":{"name":"The Angle orthodontist","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143367210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
