The search comprised prospective and retrospective studies related to the accuracy of 3D-printed models, splints, implant surgical guides, and retainers/aligners in patients undergoing orthodontic and orthognathic surgical procedures. The outcomes were assessed in terms of linear measurements, degree of fit, and positional deviations in comparison to conventional plaster models and surgical acrylic splints. The methodologic quality of the articles and the level of evidence were assessed using the QUADAS-2 tool. A meta-analysis was performed to compare the accuracy of models printed by different technologies to plaster models using the random-effects model. Twenty-one retrospective studies were included. Quality assessment of all included articles showed moderate risk of bias and no article was excluded. The systematic review showed that there were no significant differences between printed surgical splints, retainers/aligners compared, and the control group. Meta-analysis of six eligible studies showed that printed models had a general trend toward overestimation of linear measurements (mean difference = 0.22 mm; 95% confidence interval = – 0.09 to 0.36 mm, I 2 = 85%). Measurements made on digital light processing-printed models were significantly different than those made on plaster models. The mean difference of 0.22 mm in linear measurements made on 3D-printed models and plaster models was clinically acceptable. Among the various printing technologies, PolyJet and fused deposition modeling-printed models showed higher accuracy. The printed splints and retainers/aligners were as accurate and reliable as their respective gold standards. The findings should be interpreted with caution due to high level of heterogeneity.

Fifty-nine subjects with skeletal class III malocclusion treated consecutively with maxillary advancement and mandibular setback were assessed for skeletal and soft tissue linear changes using presurgical (T1) and post-treatment (T2) lateral cephalograms. Pearson’s correlation coefficient test was used to correlate hard and soft tissue parameters. The sagittal hard tissue movement and soft tissue changes for all the parameters assessed in maxilla and mandible showed statistically significant correlations. The ratios of changes for the maxillary protrusion [N-A (HP)] to horizontal subnasale (Sn), superior labial sulcus (Sls), and labrale superioris (Ls) were 0.574:1, 0.703:1, and 0.721:1 respectively. The ratio of horizontal labrale inferioris (Li), mentolabial fold (Mlf), and soft tissue (Pg′) to mandibular protrusion [N-B (HP)] were 0.992:1, 0.970:1, and 0.590:1 respectively and to chin protrusion [N-Pg (HP)] were 1.293:1, 1.252:1, and 1.001:1, respectively. The ratios were different for males and females in maxilla and mandible. Sagittal hard tissue movement and soft tissue changes are significantly correlated. The soft tissue movement in the mandible were more proportionate compared to the maxilla. The sagittal hard tissue to soft tissues movement ratios were greater in maxilla and lesser at pogonion and mentolabial sulcus in females compared to males.

Many studies have found significant relationship between the two, while others have suggested that crowding is a multifactorial condition and is not dependent on arch dimensions only. Objective: To evaluate the relationship as well as sexual dimorphism between maxillary and mandibular skeletal base lengths with dental crowding in different skeletal malocclusions. Materials and Methods: The sample comprised 100 orthodontic patients (49 males, 51 females), which were divided into three groups based on the anteroposterior relationship of maxilla with the mandible. Each group was subdivided based on the severity of mandibular and maxillary arch crowding into two subgroups, and each subgroup was further divided into male and female subjects. Measurements of maxillary and mandibular base lengths (Co-A and Co-Gn) and tooth size arch length discrepancies were obtained through lateral cephalograms and dental casts, respectively, and measurements obtained were analyzed statistically. Results: Patients with class IB, IIB, and IIIB had significantly smaller maxillary and mandibular base lengths than subjects with class IA, IIA, and IIIA. A weak negative correlation was found between maxillary base length and maxillary crowding with r = –0.451 and p = .000, while a strong positive correlation was observed between maxillary and mandibular crowding with r = 0.742 and p = .000. Conclusion: An inverse correlation exists between dental crowding and the lengths of maxillary and mandibular bases, regardless of skeletal malocclusion.","PeriodicalId":31847,"journal":{"name":"Journal of Indian Orthodontic Society","volume":"21 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140676517","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}

Methods: A three-dimensional finite element meshed model was created of the maxillofacial complex with the help of cone beam computed tomography (CBCT) digital imaging and communication in medicine (DICOM) data of a patient with transverse maxillary deficiency using materialise interactive medical image control system (MIMICS) software. Three different groups with varying expander heights were used to study the expansion effects on the maxillofacial structures. von Mises stress and displacement at various skeletal and dental points were evaluated using ANSYS software. Results: In the midpalatal suture, the posterolateral portion of the hard palate and the maxillary and pterygoid bones showed the greatest amount of stress distribution and displacement pattern. Group 1 showed the maximum amount of transverse displacement compared to groups 2 and 3. Sagittally, all the teeth had a forward displacement. Vertically, groups 2 and 3 showed clockwise rotation of the occlusal plane, while all teeth showed downward displacement in group 1. Conclusion: In conclusion, a V-shaped expansion in the maxilla with a superior and posterior vertex was noted.

In recent years, we have consistently identified a specific occurrence in the majority of lateral cephalograms, namely, the occipital spur. This refers to an enlarged external occipital protuberance, a protrusion at the rear of the skull which may manifest in either a smooth, crest, or spine-shaped configuration. Research suggests potential links to factors like brain expansion, adaptation to light levels, relief of neck muscle stress, and the influence of modern habits like smartphone usage in External occipital protuberance enlargement. Studies show a gender predilection, with smooth occipital spur more common in women and spine type more common in men, potentially aiding sex determination in forensics. Occipital spur influences on craniofacial measurements and the potential for causing occipital neuralgia, a condition characterized by pain in the posterior scalp. Management options range from conservative measures to surgical intervention, depending on symptom severity. Hence, this literature review compiles information concerning various types, prevalence, suspected etiology, clinical significance, and approaches to managing occipital spurs.","PeriodicalId":31847,"journal":{"name":"Journal of Indian Orthodontic Society","volume":" 30","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140691339","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}

Methods: The evaluation involved manually searching through archives of 15 journals divided into quartiles, that is, Q1, Q2, and Q3. Articles with at least one author affiliated with an Indian university were collected and tabulated into graphs. Results: In Q1 journals, “Progress in Orthodontics” achieved the highest Indian publication percentage at 4.66%, whereas the European Journal of Orthodontics recorded the lowest at 0.93%. Among Q2 journals, the Journal of Orthodontic Science led with a maximum publication rate of 35.83%, while the Korean Journal of Orthodontics had the least, accounting for only 0.36%. In Q3 journals, the highest contribution of 31.16% was observed in APOS Trends in Orthodontics, while International Orthodontics had the lowest contribution at 8.24%. Conclusion: The examination of 15 orthodontic journals spanning the 7 years from 2017 to 2023 revealed that the publication trends remained largely unchanged in the majority of journals across all three time periods: pre-COVID-19, during the pandemic, and post-COVID-19. Notable exceptions included a slight increase in publications observed during and after the pandemic, specifically in the American Journal of Orthodontics and Dentofacial Orthopedics (Q1 journal), Journal of Orthodontic Science (Q2 journal), APOS Trends in Orthodontics (Q3 journal), and International Orthodontics (Q3 journal).","PeriodicalId":31847,"journal":{"name":"Journal of Indian Orthodontic Society","volume":" 29","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140690919","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}

Six parameters (sector classification, three angular, and two linear) on orthopantomograms were used to assess the severity of the maxillary canine impaction. The most advanced convolutional neural network model implemented using MATLAB program was used in assessing the favorability of maxillary canine impaction. The outcome of the parameters assessed by the implemented AI model and conventional manual tracing were compared. Receiver operating characteristic (ROC) curves, diagnostic accuracy, sensitivity, specificity, and positive and negative predictive values were used to assess the performance of AI model in comparison to manual tracing for the angular and sector parameters. Paired t-tests were used for linear measurements. Results: The overall clinical performance exceeded 90% for all the angular parameters including sector classification except for the angle between long axis of canine with lateral incisor which had a specificity score of 55%. The value and the area under the ROC curve were more than 0.9 for all the parameters.
