[PMID: 34312068 DOI: 10.1016/j.jcms.2021.03.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 03/02/2021] [Accepted: 03/11/2021] [Indexed: 11/27/2022] Open
Abstract
The primary aim of this study was to explore patients' perceptions regarding the impact of 3D prediction planning (3D PP) of facial soft tissue changes following orthognathic surgery. The study was carried out on 30 patients who were shown photorealistic 3D soft tissue prediction planning before undergoing orthognathic surgery to demonstrate the expected facial changes. Distraction osteogenesis and cleft deformities were excluded from the study before consenting to surgery. Following surgery, the included patients were asked to complete a standard questionnaire to explore their perceptions regarding the impact, accuracy, and value of 3D prediction planning. The majority of the 30 participants perceived 3D PP to be beneficial in reducing their presurgical anxiety, increasing their motivation to undergo surgery, improving the accuracy of their surgical expectations, and enhancing doctor-patient communication. Most of the patients perceived their surgical soft tissue changes to be better than the predictions. Significant positive correlations were detected between satisfaction with the delivered service and the facility of seeing 3D PP (rs = 0.4; p = 0.034). Similarly, 3D PP improved patients' confidence in the surgical decision (rs = 0.4; p = 0.031), as well as increasing their motivation to undergo surgery (rs = 0.5; p = 0.010). 3D PP was found to be effective in improving the quality of orthognathic surgical care.

Abstract
Background: The evaluation of orthodontic treatment outcomes using an objective method is important in order to maintain high treatment quality and final healthcare of patients. It allows professionals and university students to raise the level of the therapy. The aim of this study was to assess the orthodontic treatment outcomes in an Italian postgraduate School of Orthodontics using Peer Assessment Rating (PAR) Index. Methods: A sample of 50 patients treated in a postgraduate program was randomly selected. PAR index was used to assess pre-treatment and post-treatment study casts by two different examiners. The influence of different variables such as gender, treatment method, and need for extraction was statistically analyzed. Results: The average numerical reduction of PAR between the beginning and the end of the treatment was 18.74 (CI 95% 16.53–20.95), while the percentage reduction was 94.8% (CI 95% 91.91–97.68). All cases improved: 8% of patients resulted in the improved category, while 92% of them were in the greatly improved group. Conclusions: According to PAR index, the results showed that patients received a high-standard therapy. None of the factors studied influenced significantly the treatment outcomes.

Abstract
Background The objective of the study was to analyze the quality control of the treatment within the orthodontic department by determining the workload, type of treatment, and quality of outcome. Method Two hundred eighty patients were selected from departmental archives, who underwent orthodontic treatment since January 2010 and assessed using index of complexity, outcome and treatment need. Descriptive statistics was performed by SPSS, version 21 (IBM, USA). Mann-Whitney U test was applied to assess the difference between complexity and improvement grade. Result Orthodontic treatment was provided to 56.43% of female and 43.57% male patients with a mean age of 16.91 years. Angle's class I type malocclusion was the highest with 35.71%. Preadjusted edgewise metal appliance with 95% dominated the mechanics. About 12.14% and 3.57% patients got benefited with myofunctional and orthopedic treatment, respectively. Ten percent of patients were treated with orthognathic surgery. The mean duration of treatment was 31.19 months with a range of minimum of 17 months to a maximum of 46 months. Among 87.14% patients treated by faculty, 47.95% had difficult complexity grading and 22.95% had very difficult complexity grading. Residents had provided treatment with 63.88% difficult and 19.44% very difficult grade. Mann-Whitney U test of overall complexity and improvement grade showed Z score of -9.25715 which was highly significant. Conclusion The present study concludes that fair quality control is being maintained by the department considering the number of patients, its severity, and excellent outcomes. However, being the premier institute of Indian Armed Forces, regular clinical audit should be conducted to fulfill demand and supply ratio in appropriation.

Abstract
Objective In Turkey, orthodontic treatments of individuals aged <18 years are covered by the Social Security Institution (SSI) according to the Index of Complexity, Outcome, and Need (ICON) index at contracted healthcare providers. The aim of this study was to determine treatment needs and difficulties of patients applying to orthodontic clinics in state and foundation universities in Istanbul according to the ICON and to evaluate the extent of treatment coverage by the SSI. Methods Pre-treatment study casts of 831 patients were evaluated in terms of treatment needs and difficulties according to the ICON. This sample was distributed as 677 patients who applied to a State University's Orthodontic Department and 154 who applied to a Foundation University's Orthodontic Department. Results At the state university, 27.9% of the 437 patients had a score of <43 and were thus, described as "no treatment needed." At the foundation university, 35% of the 154 patients had a score <43 and were thus, described as "no treatment needed." When the ICON scores of the two universities were compared, no statistically significant difference was found between treatment needs distributions. Conclusion The number of patients who applied for treatment for the same period was three times higher in the state university than in the foundation university, whereas the rates of treatment needs were found to be similar between both state and foundation universities. At both universities, nearly one-third of patients were evaluated as "no treatment needed." The ICON index was found to be a reliable index in terms of reproducibility.

Abstract
Studies of orthognathic surgery often focus on pre-surgical versus post-surgical changes in facial shape. In contrast, this study provides an innovative comparison between post-surgical and control shape. Forty orthognathic surgery patients were included, who underwent three different types of surgical correction: Le Fort I maxillary advancement, bilateral sagittal split mandibular advancement, and bimaxillary advancement surgery. Control facial images were captured from volunteers from local communities in Glasgow, with patterns of age, sex, and ethnic background that matched those of the surgical patients. Facial models were fitted and Procrustes registration and principal components analysis used to allow quantitative analysis, including the comparison of group mean shape and mean asymmetry. The primary characteristic of the difference in shape was found to be residual mandibular prognathism in the group of female patients who underwent Le Fort I maxillary advancement. Individual cases were assessed against this type of shape difference, using a quantitative scale to aid clinical audit. Analysis of the combined surgical groups provided strong evidence that surgery reduces asymmetry in some parts of the face such as the upper lip region. No evidence was found that mean asymmetry in post-surgical patients is greater than that in controls.

Abstract
The Peer Assessment Rating (PAR) index is a valid and reliable measure of orthodontic treatment outcome and is the most widely accepted such index. Assessing outcomes with the PAR index requires the examination of pre-treatment and post-treatment orthodontic study models. Beginning with the pre-treatment models, a score is given to each feature that deviates from an ideal occlusion (all anatomical contact points adjacent, good interdigitation between posterior teeth and non-excessive overjet/overbite), the scores are then added together to give a total that represents the severity of the malocclusion. The process is then repeated with the post-treatment models. The difference between the pre-treatment and the post-treatment scores reflects the improvement that has taken place during treatment. A score of zero represents an ideal occlusion and in general the higher the score, the more extensive the malocclusion. It is currently a condition of the NHS orthodontic contract for providers to monitor a proportion of their cases using the PAR index. This paper aims to provide primary dental care practitioners with an overview of the PAR index and should provide a useful guide for those wishing to seek calibration in the use of the index.

Abstract
OBJECTIVE The objective of this study is to analyze the association between self-reported symptoms of temporomandibular joint disorder (TMD) and the severity of malocclusion in prospective orthognathic-surgical patients. MATERIAL AND METHODS The subjects consisted of 50 consecutive patients (13 males and 37 females) referred to two university clinics for assessment of orthodontic-surgical treatment need. Data considering self-reported TMD symptoms were gathered using a semi-structured diary. At the first appointment, all patients rated the importance of treatment (on a scale of 1-10) and assessed self-perceived dental appearance using a VAS scale. The scale was anchored with photographs 1 and 10 from the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). Study models were assessed by an experienced orthodontic specialist using the Peer Assessment Rating (PAR) index and the Index of Complexity, Outcome and Need (ICON). Association between the PAR and ICON scores and the number of reported symptoms was analyzed statistically. RESULTS Seventy-one percent of patients reported experiencing TMD symptoms. The most prevalent symptoms were pain in the head and/or neck region and fatigue in the TMJ region. The number of symptoms was highest in the morning. Ninety percent of males and 86% of females rated the importance of treatment as high; males experiencing TMD symptoms tended to rate surgery as more important compared with males with no symptoms (p = 0.056). CONCLUSIONS In this sample, the results cannot unambiguously confirm an association between self-reported symptoms of TMD and objectively defined severity of malocclusion.

Abstract
To validate the use of the Index of Complexity, Outcome and Need (ICON) in assessing orthodontic treatment need among 12–13 year-olds in southern China, we determined the threshold value of ICON based on Chinese orthodontists' judgments. The samples consisted of 335 students in grade 7 from 16 randomly selected middle schools in Chengdu, China. Three associate professors provided ICON scores for each participant and the results were compared with the gold standard judgments from 25 experts on treatment needs. Based on the gold standard, 195 casts belonged to the treatment category, while the rest 140 belonged to the no-treatment category. With the international cutoff point of 43, the sensitivity and specificity of the ICON score were 0.29 and 0.98. The best compromise between sensitivity and specificity in Chengdu, compared with the gold standard, was found at a cutoff point of 29, and the sensitivity and specificity were 0.88 and 0.83. When used to evaluate the treatment need of 12–13 year-olds in southern China, the international ICON cutoff value did not correspond well with Chinese orthodontists' judgments; a lower cutoff value of 29 offered a greater sensitivity and specificity with respect to expert orthodontists' perception of treatment need.

Abstract
The Peer Assessment Rating (PAR) index is commonly used to evaluate occlusal outcomes after orthodontic treatment. We compared the PAR outcomes of 40 consecutively treated orthodontic patients and 40 orthognathic patients to evaluate the standard of care given. A patient-centred questionnaire was used to examine patients' perceptions of the benefits of orthognathic treatment. PAR scores of orthodontic and orthognathic patients improved by a mean of 77% and 74%, respectively, after treatment indicating that excellent to good occlusal results were achieved for both groups. A high quality occlusal outcome is important for all patients as good intercuspation at the end of treatment is thought to improve stability. Most orthognathic patients reported improvements in their dental and facial appearance and thought that the treatment had been beneficial.

Abstract
The benefits of early orthodontic treatment are continuously discussed, but studies are few. We examined whether definite need for orthodontic treatment could be eliminated in public health care by systematically focusing on early intervention. One age cohort living in a rural Finnish municipality (N = 85) was regularly followed from ages 8 to 15 years, and persons with malocclusions were treated according to a pre-planned protocol. Treatment need was assessed according to the Dental Health Component (DHC) of the Index of Orthodontic Treatment Need, and treatment outcome by the Peer Assessment Rating Index (PAR). Fifty-two percent of the cohort received treatment, and definite treatment need decreased from 33% to 9%. In the treated group, the mean PAR score reduction was 63%, and 51% showed more than 70% improvement. The results suggest that an early treatment strategy may considerably reduce the need for orthodontic treatment in public health care with limited specialist resources.

Abstract
INTRODUCTION A 4-year collaborative project between the American Board of Orthodontics (ABO) and 15 American orthodontic graduate programs concluded at the ABO Clinical Examination in February 2006. METHODS Fifty recent graduates (the pilot study group) presented cases that were treated in their graduate programs as partial fulfillment of the requirements for ABO certification. The examinees were tested by calibrated ABO examiners and required to satisfy traditional ABO standards. They presented appropriate case reports that contained the ABO's 3 measurement instruments. Thirty-nine practicing orthodontists (the control group) presented cases according to the traditional ABO Clinical Examination process. RESULTS Ninety percent of the pilot study group and 85% of the control group successfully accomplished ABO certification. There was a difference of 2.38 points between the 2 groups for the mean total scores of the cases that passed. The pilot study group presented cases that met the historic averages for case complexity (discrepancy index). CONCLUSIONS Residents in orthodontic programs are able to treat cases to ABO standards of quality.
