Our work aims to provide scientific evidence by conducting a serious systematic review of the efficacy of three-dimensional (3D) anchorage devices for orthodontic traction of impacted maxillary canines. An electronic search extending from 2012 to 2022, targeting mainly clinical trials was performed on the following databases PUBMED (MEDLINE), The Cochrane Library, SCIENCE DIRECT, EBSCO HOST DATABASES, and GOOGLE SCHOLAR. The search was established on a well-defined research question following the PICO principle: population, intervention, comparator, and outcome. Search evaluation and the assessment of the risk of bias (RoB) were undertaken in each study following its type and design. Thirteen studies were included for qualitative analysis, with a low to moderate RoB. Ten studies used only heavy conventional palatal anchorage such as a fixed trans palatal arch (TPA), while one study used skeletal anchorage to manage the orthodontic traction of impacted maxillary canines. Two studies compared trans palatal arch and mini-screws efficiency to treat impacted maxillary canines. Studies proved that the trans palatal arch (TPA) presents a particular anchorage unpredictability in the sagittal, transversal, and vertical dimensions. Whereas, anchorage management using mini-screws proved to be very beneficial clinically; however, further studies must be implemented to evaluate the 3D efficacy of skeletal anchorage to place an impacted maxillary canine to its rightful position into the arch.

The aim of this study is to examine the relationship between occlusal factors and temporomandibular joint diseases (TMD). In our study, 43 individuals who had fixed orthodontic treatment and 20 individuals who did not need treatment at Istanbul Aydin University Faculty of Dentistry Department of Orthodontics were included in the study. Evaluations were made at the beginning of treatment (T0) and at 6 months (T1). T-Scan® computerized Occlusion Analyzer was used to evaluate the number of contact points, occlusal force parameters during centric occlusion and lateral movements, and occlusion and disclusion times. Differences between groups were evaluated with Mann–Whitney or independent t-test, and within-group differences were evaluated with Wilcoxon sign test or paired t-test, depending on whether the data showed normal distribution or not. There was no statistically significant distinction between the gender-based parameters and right and left joint of Joint Vibration Analysis record in all three groups (P > 0.05). At the beginning of orthodontic treatment, there was no statistical difference in the variables within the group and between the groups. As a result of the comparison between the beginning of treatment (T0) and the 6th month (T1), no significant difference was found between the parameters of the anterior/posterior occlusal force distribution of the right-left quadrant and the force distribution of the working and non-working sides in lateral movements, and the occlusion and disclusion time parameters. Maximum intercuspal position left/right (MxlntlTSCANT1) was found to be statistically significant at 6 months in individuals who received fixed orthodontic treatment with extraction compared to the none xtraction treatment group (P < 0.05). According to our research, T-scan is one of the best devices for the early detection of TMD, especially for people undergoing orthodontic treatment. T-scan offers fast, non-invasive, and repeatable occlusion recording.

A questionnaire, specific to the clinical condition treated is important. The aim of this study was to evaluate the Quality of life (QOL) amongst patients undergoing orthognathic surgery using a customized questionnaire encompassing, patients’ perception of facial form and also patient perception of overall quality of care provided during the entire treatment. This prospective, qualitative, observational study was carried out on 21 patients, who underwent Ortho-surgical management between Jan 2019 and Mar 2020. The Orthognathic QOL questionnaire was customized, Phase I, immediately prior; and Phase II, 6 months after surgery. Appropriate analysis was done to compare Phase I and Phase II, with the level of significance set to P < 0.05. “Aesthetics” was the most frequent reported reason for seeking treatment. The mean pre-/post-treatment difference for oral function was statistically significant. Majority (87%) of patients reported surgical outcomes met their expectations. Results, post-surgery; good hospital care (33.3%), supportive doctors (28.57%) and regular follow up (9.52%). “Patients’ perspective” of treatment, is often neglected, the immense importance of which has been duly reflected in our study. We recommend the use of our questionnaire in a similar, broad based multicentric study with a larger patient base, will aid in improving overall outcome of ortho-surgical interventions.

The objectives of the study were to evaluate and compare the antimicrobial property of nanochitosan coated and uncoated stainless steel (SS) brackets against Streptococcus mutans and Lactobacillus acidophilus. 22 SS orthodontic brackets coated with nanochitosan and 22 uncoated brackets were bonded to the crowns of extracted premolar teeth and prepared for the antimicrobial assay against S. mutans and L. acidophilus. The bacterial suspensions were incubated in Mueller Hinton broth and cultivated in Petri dish plates. The bacterial colonies were counted after 1, 6, 12, 24, and 72 h intervals using a digital colony counter. Inter and intragroup comparisons were done using independent sample t-test and repeated measures ANOVA (P ≤ 0.05). The mean colony-forming units (CFU) of S. mutans and L. acidophilus showed a significant reduction in the coated brackets from 1 h to 72 h (P = 0.000). The mean CFU of S. mutans and L. acidophilus showed a significant increase in the uncoated brackets from 1 h to 24 h and decreased thereafter at 72 h (P = 0.000) except for S. mutans between 12 h and 72 h where the difference was not statistically significant (P = 0.837). The Mean CFU of S. mutans and L. acidophilus was significantly lesser in coated brackets compared to uncoated brackets at all-time intervals (P = 0.000). Nanochitosan coated orthodontic brackets showed significant antimicrobial properties against S. mutans and L. acidophilus in short-term up to 72 h compared to uncoated SS brackets.

The purpose of this study was to evaluate the amount of root repair that took place at varying intervals of 1 day, 2 weeks, 4 weeks and 8 weeks after intentional contact with microscrews. The results were evaluated by an environmental scanning electron microscope study (E-SEM). Ten orthodontic patients with 2 maxillary and 2 mandibular first premolars (40 premolars) to be extracted as part of the orthodontic treatment were included in this study (age 18–25 years). The position of the roots of the 4 premolars to be extracted was clinically determined and under local anesthesia, microscrew implants were placed in such a way that they directly hit the root from the buccal aspect. Implants were removed immediately after the above-mentioned procedure was performed. On the same day, premolar of the 1st quadrant (Group I) was extracted. Premolar of the 2nd quadrant (Group II) was extracted 2 weeks later. Premolar of the 3rd quadrant (Group III) was extracted 4 weeks later and premolar of the 4th quadrant (Group IV) was extracted 8 weeks later, from the day of intentional damage. Significant changes were observed in the deposition of cementum over 8 weeks which were analyzed using ESEM under magnifications of × 50, × 200, × 500, and × 5000. The damaged root surfaces due to intentional contact with microscrews showed swift repair and healing within 8 weeks. In case, the root is damaged due to improper placement technique or wrong biomechanics which may result in the implant touching the root surface, a minimum healing period of 8–10 weeks is advocated before commencing further tooth movement.

The teeth position in anterior open bite malocclusion depends on a balance of pressure between the tongue and lips and the treatment planning should include such variables. The objective of this study was to report an orthodontic case of an adult with maxillary protrusion and anterior open bite treated with skeletal anchorage and intermaxillary elastics. The patient presented a Class II malocclusion with anterior open bite, without a history of non-nutritive habits, and mandibular missing teeth at 54 years old. Mini-implants were inserted in the maxillary molars region to produce distal movement of the maxillary dentition while controlling molar extrusion, and in the mandibular anterior region on the left side to produce mesial movement of posterior teeth. Up and down intermaxillary elastics were worn in the area of the incisors to treat the open bite together with Class II intermaxillary elastics. Cleats were bonded in the lingual surface of the anterior teeth as spurs to the tongue posture. However, the best result on the anterior open bite treatment was coincident with the speech therapy. Normal relationships between the maxillary and mandibular occlusal plane of cusps, correct anterior overbite, and adequate proximal relationships were obtained at the end of treatment. The retention modality to the maxillary arch was daily wear of a removable standard wraparound and a night-time wraparound with the palatal crib. The new technology allows for more effective treatment in adults and speech therapy was helpful to achieve balanced pressure between the tongue and lips.

Orthodontists generally recommend avoidance of certain foods during fixed appliance (FA) treatment, based on anecdotal information. This study aimed to identify the dietary preferences and experiences of patients undergoing FA treatment as a step toward the preparation of evidence-based dietary guidelines. Questionnaires regarding dietary preferences and experiences of patients undergoing FA treatment were applied to a convenience sample of 38 adolescents (12 M; 26 F). Open-ended responses were summarized and visualized in a world cloud generator. 5-point Likert and Visual Analog Scales (VAS) were used to record the closed-ended responses. Descriptive statistics and multivariate analysis of variance were used to analyze questionnaire findings. Lollies, apples, and nuts frequently caused problems with FA. The most frequent reason for avoiding certain types of food was worry about appliance breakage, followed by pain and sensitivity. VAS scores indicated that toffee and caramel scored highest (65.1% F and 54.1% M) for discomfort followed by corn on the cob (64.4% F and 48.7% M) and apples (56.6% F and 55.3% M). VAS scores did not differ significantly between the sexes (P > 0.05). Nearly, a quarter of the sample reported that FA negatively affected their eating behaviors, causing pain and discomfort during eating. No sex differences (P > 0.05) were found for negative experiences with food. Dietary preferences and experiences of patients undergoing FA treatment were identified concerning a New Zealand diet profile. A future study with a larger sample size will help formulate evidence-based dietary guidelines during FA treatment.

Smile is a universal phenomenon, the effect of which is not discovered on the lower anterior facial height (LAFH). The objective of this study was to determine the influence of smile on different LAFH in frontal view as assessed by different panels of raters using visual analog scale (VAS) in a female subject. The frontal photographs (at rest and on smile) were taken at natural head position of a female subject aged 28 years old after taking informed consent. LAFH of the photographs was modified using a Photoshop software (Adobe Systems, San Jose, Calif.). Sixty raters equally divided into orthodontic residents, general dentists, and laypersons were given a VAS to make subjective assessments of facial attractiveness of the modified photographs. Comparison of raters’ scores was done using Kruskal–Wallis and Mann–Whitney U-tests. Wilcoxon Signed-Rank test was used to compare the esthetic scores of the subject at rest and with smile. The mean age of the all raters was comparable (early adulthood). All raters preferred normal or slightly shorter LAFH in both postures, that is, at smile and rest. Similarly, all raters disliked long face modifications. On comparing smile and rest photographs at various LAFH, we found less VAS scores for smile. Gender of raters played no role in difference of VAS scores. All the panels of rater found normal LAFH to be the most attractive; however, the panels disliked long face modifications on both smile and at rest. Smile had no positive influence on the VAS scores as assumed so the effect of “Smiloflage” must be investigated further to understand it properly.

All raters preferred normal or slightly shorter LAFH in both postures, that is, at smile and rest. Similarly, all raters disliked long face modifications. On comparing smile and rest photographs at various LAFH, we found less VAS scores for smile. Gender of raters played no role in difference of VAS scores.\u0000\u0000\u0000\u0000All the panels of rater found normal LAFH to be the most attractive; however, the panels disliked long face modifications on both smile and at rest. Smile had no positive influence on the VAS scores as assumed so the effect of “Smiloflage” must be investigated further to understand it properly.\u0000","PeriodicalId":42593,"journal":{"name":"APOS Trends in Orthodontics","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89889489","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 intraoral use of commercial printable polymers in dental patients is still a challenge due to the unknown physical properties of the materials. The present study aimed to comparably evaluate the maximum load and deflection values of three-dimensional-printed resin blocks in different diameters that can be used intraorally in dental patients. Forty-five cylindrical resin blocks in diameters of 2 mm (Group 1, n = 15), 3 mm (Group 2, n = 15), and 4 mm (Group 3, n = 15) and lengths of 20 mm were designed and printed. The samples were placed in the universal testing device to conduct the 3-point bending test. According to the Shapiro–Wilk normality test results, Kruskal–Wallis and Mann–Whitney U tests were performed for the statistical analysis. The level of statistical significance was accepted as P < 0.05. The values for the maximum load (N) and deflection (mm) in the study groups were 218.4 ± 31.9, 2.96 ± 0.86 in Group 3; 77.05 ± 61.5, 3.91 ± 0.92 in Group 2; and 19.67 ± 2.63, 4.06 ± 1.02 in Group 1, respectively. The mean values of maximum load for Group 3 were superior to Group 2 (P = 0.020) and Group 1 (P = 0.00). Group 2 revealed higher maximum load results than Group 1 (P = 0.003). The mean values of maximum deflection in Group 3 were lower compared to Group 2 (P = 0.014) and Group 1 (P = 005). The results of this in vitro study encourage the use of resin-printed intraoral appliances in place of conventional treatment modalities.

The treatment plan for young patients with skeletal abnormalities is often selected by their parents. However, the treatment outcome should correspond with the patient’s preference to reduce the treatment need in the future. This study aimed to investigate the influence of post-treatment facial profiles in a skeletal Class II female subject on esthetic perceptions by laypeople of different age groups. Seven digitally adjusted profile images of predetermined nasolabial angle (NLA) and facial contour angle (FCA) were obtained from a female with skeletal Class II. These profile images were evaluated by 180 laypeople and were stratified according to three age groups (12–15, 22–32, and 44–54 years) using a visual analog scale and ranking order. The slightly convex profile with normal NLA (11° FCA and 91° NLA) was the most preferred by all age groups. The convex profile with the largest NLA (17° FCA and 115° NLA) was the least preferred by age group 12–15 and 44–54 years and the convex profile with normal NLA (17° FCA and 91° NLA) was the least preferred by age group 22–32 years. Sex was found to be significantly related to the rating score with females rated higher scores. The most attractive profile for all three age groups was a mandibular advancement-simulating profile. The least attractive profile for age groups 12–15 and 44–54 years was a most camouflage-simulating profile, while the least attractive profile for age group 22–32 years was an untreated most pronounced Class II profile.
