RESUMO

INTRODUCTION: The cervical vertebral maturation (CVM) method comprises 6 stages reported to be prepubertal (1 and 2), pubertal (3 and 4) and postpubertal (5 and 6), and its use has been recommended for planning treatment timing in orthodontics. Reliable use of the method implies that pubertal stages have to mature into postpubertal as soon as the growth peak is terminated. The present study was aimed at determining whether postpubertal CVM stages 5 or 6 are attained in all subjects. METHODS: A total of 450 adult subjects (270 females and 180 males; mean age, 30.4 ± 27.3 years; range, 20-45 years) seeking orthodontic treatment and having a lateral head film were included in the study. Customized cephalometric analysis was used, and each recording was converted into an individual CVM code according to the concavities of the C2 to C4 and shapes of C3 and C4. The retrieved CVM codes, either falling within the reported norms (regular cases) or not (exception cases), were also converted into the CVM stages and a newly introduced CVM score (0-9) capable of defining intermediate stage. RESULTS: The most frequent CVM stage was 5, while the CVM stage 6 was attained in only one third of the sample. Up to about 11% of adult subjects showed the pubertal CVM stage 4. Irrespective of the CVM stage or CVM score, no significant differences were seen between the sexes or across ages. The C4 showed a rectangular vertical shape in only 16.4% of the cases. CONCLUSIONS: The percentage of adult population maintaining a pubertal CVM stage 4 is not high, but still relevant from a clinical standpoint. In light of this finding, planning treatment timing-based only on CVM appears not fully reliable.

RESUMO

PURPOSE: To examine the main factors affecting the quality of orthodontic treatment. MATERIAL AND METHODS: the survey was conducted over 3 years in 158 orthodontists who participated advanced training in the Departments of Therapeutic Dentistry, Pediatric Dentistry and Orthodontics. A questionnaire was drawn up for the survey including 4 sets of questions: diagnosis, treatment planning, completion and retention, documentation. The results obtained suggest that doctors who were interviewed conducted a complex of diagnostic measures 49.37%, an aesthetic index was never used in the diagnosis in 91.14% of respondents; diagnostic analysis of control and diagnostic models is not carried out by 72.78%, 15.19% use cone-beam computed tomography. In the course of treatment 50.63% conduct individualization of orthodontic equipment, 63.29% perform detailed bends. The rate of orthodontic retreatment in high as 63.92% of orthodontists has the corresponding experience. Completing the treatment process only 13.29% of orthodontist perform a complete analysis of occlusal contacts. Storage of medical records is possible for up to 3 years in 31.01%, up to 5 years in 34.81% of respondents, but 78.48% reported problems with storage space in clinics. CONCLUSION: There are issues that require clarification in the course of continuous education which are: rendering of a computerized X-ray examination; clinical review of cases causing difficulties; identifying and determining the causes of recurrent orthodontic treatment.

RESUMO

INTRODUCTION: The objective of this study was to assess the reproducibility of cervical vertebral maturation (CVM) method based on the type of radiographic image and the level of experience and level of training of the evaluator. METHODS: Ten evaluators (5 orthodontic residents and 5 faculty members) were randomly divided into 2 groups: trained and untrained. All participants evaluated 80 radiographic images previously acquired in 4 different formats: (1) 2-dimensional (2D) digital (2D-digital), (2) 2D digitized hard copy from the Iowa Facial Growth Study (American Association of Orthodontists Foundation Craniofacial Growth Legacy Collection), (3) 2D digital reconstructed from a 3-dimensional (3D) radiograph (2D-from 3D), and (4) 3D cone-beam computerized tomographic (3D-CBCT) images. Agreement among evaluators on the morphology of the cervical vertebrae (CV) and the CVM stage of each radiographic image was assessed using Randolph's kappa statistic and Kendall's W coefficient of concordance. RESULTS: Interobserver agreement on the determination of a curvature on the inferior border of the CV was substantial to perfect, whereas agreement on shape was fair to moderate. Overall, the level training in all image types, except 3D-CBCTs, but not the level of experience affected the agreement for shape and curvature of the CVs. Interobserver agreement on CVM staging for all combined images was substantial at 0.72. Faculty had a higher level of agreement than residents except for 2D-digital and 3D-CBCT images, whereas trained evaluators had an overall higher level of agreement than untrained evaluators except for 3D-CBCT images. CONCLUSIONS: Interobserver agreement in determining CVM stage was substantial for all images evaluated; experience and training resulted in higher level of agreement for some image types. The 3D-CBCT images did not provide increased interobserver agreement over current 2D-digital lateral cephalograms in determining CVM staging or shape of the CV. The highest agreement in CVM staging was obtained on 2D-digital lateral cephalograms with training.

RESUMO

INTRODUCTION: Communication of treatment information is critical in orthodontics. The challenge lies in doing so effectively such that patients will understand and remember, which is the definition of true informed consent. Previous studies have established that information is more readily remembered when presented using multimedia presentations. Likewise, humor has been shown to increase information retention. METHODS: Two videos, 1 humorous (H) and 1 unhumorous (U), were produced with identical information about orthodontic treatment consent. Thirty-eight new orthodontic patients were randomly selected and divided into H (n = 20) and U (n = 18) video groups. Identical questionnaires with multiple-choice responses to judge memory of the content were completed by both groups immediately after watching the video (T1) and 6 weeks later (T2). A one-tailed Welch's t test was used to analyze the scores. RESULTS: At T1, there was no significant difference in the scores of the questionnaire between H and U groups, whereas at T2, there was a significant difference between groups. The intragroup score difference was also analyzed, with a significant decrease from T1 to T2 in the U, but not H, group. Subjective questions were also asked regarding content. No significant differences were found between the groups regarding the informativeness of each video; however, willingness to watch again and memorability of the content were significantly higher in the H group. CONCLUSIONS: Patients who received orthodontic treatment information presented with humor retained significantly more of that information after 6 weeks compared with patients who received the same information without humor. Patients who received the humorous content subjectively stated they were more likely to rewatch the video and also found the information presented in this manner to be more memorable.

RESUMO

INTRODUCTION: The goal of this research was to assess the impact of orthodontic root movement on gingival recessions. METHODS: Twelve consecutive adult patients with a mandibular incisor presenting buccal or lingual gingival recession and with the root positioned outside the alveolar bone were enrolled. The roots were moved toward the center of the alveolar process with a goal oriented segmented appliance. The following variables were measured at baseline and after orthodontic treatment: (1) recession depth, (2) recession width, and (3) recession area. In addition, pocket probing depth, keratinized tissue height, and changes in Miller's classification were registered. RESULTS: The depth, width, and area of the gingival recessions were reduced in all patients without increased pocket probing depth. On average, the recession depth decreased with 23%, the width with 38%, and the recession area with 63% of the baseline value. All patients improved in Miller's classification from Class III and IV to Class I or II. CONCLUSIONS: Orthodontic correction of the root toward the center of the alveolar envelope consistently reduced gingival recessions. The changes in Miller's classification indicated improved prognosis for full root coverage with mucogingival surgery.

RESUMO

The aim of this study was to compare the effectiveness of live-video and video demonstration methods in training dental students in orthodontic emergency applications. A total of 105 fifth-year dental students at a dental school in Turkey participated in the study in 2018. A pretest was given to the students to evaluate their level of knowledge about band cementing and re-bonding of brackets. Subsequently, two clinical applications were demonstrated with either live-video or video demonstration. During the live-video demonstration, the lecturer gave information about the steps of the procedure while performing the clinical application on the patient using a camera attached to the loupes. The students were able to see the process on the screens. During the video demonstration, previously recorded videos of those clinical applications were shown, and information was given to students in a classroom. On the next day, posttests were given to the students. The posttest also asked students to give their opinions about both methods. The results showed that the mean posttest scores on the video demonstration were significantly higher than on the live-video demonstration. However, no significant difference between the demonstration methods was found with regard to increase of scores from pre- to posttest. Most students preferred use of the two demonstrations together for education in the clinical orthodontics lecture. This study found that the two demonstration methods had comparable effects on increasing students' level of knowledge. However, from the students' perspective, the two should be used together to achieve the highest effect.

RESUMO

INTRODUCTION: Cone-Beam Computed Tomography (CBCT) images can be superimposed, allowing three-dimensional (3D) evaluation of craniofacial growth/treatment effects. Limitations of 3D superimposition techniques are related to imaging quality, software/hardware performance, reference areas chosen, and landmark points/volumes identification errors. The aims of this research are to determine/compare the intra-rater reliability generated by three 3D superimposition methods using CBCT images, and compare the changes observed in treated cases by these methods. METHODS: Thirty-six growing individuals (11-14 years old) were selected from patients that received orthodontic treatment. Before and after treatment (average 24 months apart) CBCTs were analyzed using three superimposition methods. The superimposed scans with the two voxel-based methods were used to construct surface models and quantify differences using SlicerCMF software, while distances in the landmark-derived method were calculated using Excel. 3D linear measurements of the models superimposed with each method were then compared. RESULTS: Repeated measurements with each method separately presented good to excellent intraclass correlation coefficient (ICC ≥ 0.825). ICC values were the lowest when comparing the landmark-based method and both voxel-based methods. Moderate to excellent agreement was observed when comparing the voxel-based methods against each other. The landmark-based method generated the highest measurement error. CONCLUSIONS: Findings indicate good to excellent intra-examiner reliability of the three 3D superimposition methods when assessed individually. However, when assessing reliability among the three methods, ICC demonstrated less powerful agreement. The measurements with two of the three methods (CMFreg/Slicer and Dolphin) showed similar mean differences; however, the accuracy of the results could not be determined.

RESUMO

Many of the aesthetic facial procedures can be performed simultaneously at the time of initial orthognathic surgery. Correction of any residual deformities after surgery, such as mandibular notching, malar asymmetry, labiomental crease, and any camouflage treatment, should be performed as a delayed procedure, when the outcome is more predictable. Additionally, these procedures could be used to enhance the orthodontic result, without the need of osteotomies to reposition the bones.

RESUMO

Post orthognathic surgery patient management is critical for high-quality and predictable outcomes. Surgeons and orthodontists must have the knowledge and ability to implement postsurgical management protocols and strategies to provide the best care and outcomes possible. This article presents basic concepts, philosophies, treatment protocols, risks, and potential complications associated with postsurgical patient management. Postsurgical orthodontic goals are to maximize the occlusal fit and provide predictable means to retain the occlusion. Aggressive orthodontic mechanics may be required to provide the best occlusal fit. Complications can occur, but early recognition of complications and implementation of corrective tactics should minimize adverse outcomes.

RESUMO

Complications in orthognathic surgery are commonly a result of inadequate preoperative planning and communication between the surgeon and orthodontist. Unfavorable outcomes can often be avoided when overall treatment goals along with a surgical and orthodontic plan are developed and agreed upon by the orthodontist, surgeon, and patient before the start of active tooth movement or any surgical procedures. Continuous evaluation of the patient's progress throughout treatment and subsequent communication between the surgeon and orthodontist are recommended to prevent frequent errors, such as inadequate dental decompensation, poor appliance selection or management, and occasional contraindicated orthodontic elastic traction or tooth movements.

RESUMO

The aim of the present study was to compare the effect of traditional orthodontics and Piezocision-assisted orthodontics on the periodontal status and rate of canine retraction. In a split-mouth study, 20 subjects undergoing orthodontic treatment were selected. Conventional orthodontics was performed on 20 canine sites (control side), and contralateral canines were subjected to Piezocision-assisted orthodontics (experimental side). The experimental side showed statistically significant increase in rate of canine retraction as well as an increase in alveolar bone level in mesial and buccal aspects.

RESUMO

PURPOSE: The aim of this investigation was to create an automated cephalometric X­ray analysis using a specialized artificial intelligence (AI) algorithm. We compared the accuracy of this analysis to the current gold standard (analyses performed by human experts) to evaluate precision and clinical application of such an approach in orthodontic routine. METHODS: For training of the network, 12 experienced examiners identified 18 landmarks on a total of 1792 cephalometric X­rays. To evaluate quality of the predictions of the AI, both AI and each examiner analyzed 12 commonly used orthodontic parameters on a basis of 50 cephalometric X­rays that were not part of the training data for the AI. Median values of the 12 examiners for each parameter were defined as humans' gold standard and compared to the AI's predictions. RESULTS: There were almost no statistically significant differences between humans' gold standard and the AI's predictions. Differences between the two analyses do not seem to be clinically relevant. CONCLUSIONS: We created an AI algorithm able to analyze unknown cephalometric X­rays at almost the same quality level as experienced human examiners (current gold standard). This study is one of the first to successfully enable implementation of AI into dentistry, in particular orthodontics, satisfying medical requirements.

RESUMO

PURPOSE: To explore the aesthetic effect of orthodontics treatment combined with periodontal splint in the treatment of fan-shaped displacement of anterior teeth caused by periodontitis. METHODS: Fifty patients with fan-shaped displacement of anterior teeth caused by periodontitis in PLA air force hospital from January 2013 to October 2018 were selected and randomly divided into the control group (n=25) and the experimental group (n=25). Patients in the control group were treated with conventional periodontal splint, while patients in the experimental group were treated with combined orthodontic treatment on the basis of the control group. Florida periodontal probe exploration depth (PD), gingival index (GI), attachment loss (AL), sulcus bleeding index (SBI), plaque index (PLI) and mobility were observed and compared before and 1 month after treatment between both groups. The levels of serum inflammatory factors interleukin-4 (IL-4), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP) and osteocalcin (OC) were measured and compared by ELISA before treatment and 1 month after treatment in both 2 groups. The data were analyzed with SPSS 21.0 software package. RESULTS: Compared with before treatment, PD and GI in both groups decreased significantly after treatment, and significantly lower in the experimental group than that in the control group (P<0.05); the levels of AL, SBI, PLI and tooth looseness in both 2 groups were significantly lower after treatment, and significantly lower in the experimental than in the control group (P<0.05); compared with before treatment, the levels of IL-4, IL-6, TNF-a and serum CRP in both 2 groups were significantly lower after treatment, and the experimental group was much lower than that in the control group (P<0.05). The level of osteocalcin in the experimental group was significantly higher than that in the control group at different time points after treatment (P<0.05). The level of osteocalcin in the experimental group reached its peak one day after treatment, and then gradually declined, the preoperative level was basically restored 7 days after treatment. CONCLUSIONS: Using orthodontics combined with periodontal splint in the treatment of fan-shaped displacement of anterior teeth caused by periodontitis has a remarkable effect. The symptoms of periodontitis can be effectively improved, the teeth can be effectively corrected and facial profiles of the patients can be improved.

RESUMO

Objectives: To assess the validity of using the calibration ruler for correcting magnification of linear measurements and to explore and compare the vertical and horizontal magnification of four digital cephalometric units. Methods: An acrylic box was imaged at seven sagittal positions using four digital cephalometric units: Orthopantomograph OC100, Orthopantomograph OC200, Sirona Orthophos CD, and Sirona Orthophos DS. The true linear lengths of the phantom, corrected, and uncorrected linear lengths on the images were measured and compared. The validity of measurements using the calibration ruler was assessed. The magnification values and distortion indices were calculated and compared among the four cephalometric units. Results: For linear measurements on the mid-sagittal plane and averaged linear measurements on bilateral symmetric sagittal planes, the bias 1.96 STD of the calibration ruler ranged from 1% to 2% for the four cephalometric testing units. For linear measurements on the single lateral sagittal plane, the bias 1.96 STD ranged from 3% to 6%. The vertical scanning charge-coupled device cephalometric unit produced the greatest distortion, ranging from 1.029 to 0.964. Conclusion: The metal millimeter calibration ruler is an accurate reference for linear measurement magnification correction. Because of unpredictability and machine specificity, the magnification and distortion of a cephalometric unit should be calibrated for the estimation of cephalometric measurement error.

RESUMO

Terminado el tratamiento de ortodoncia, el objetivo principal es mantener la estabilidad oclusal a largo plazo evitando la recidiva, y esto es posible utilizando una contención fija posortodoncia. El propósito de esta investigación fue evaluar los diferentes métodos que existen para el control de placa bacteriana en los pacientes con contención fija posortodoncia y como podrían afectar el estado de salud periodontal. Existen muchos estudios a corto y largo plazo sobre este tema, pero no hay uno que realmente indique que existen efectos negativos. Sin embargo, se conoce que estos pacientes tienen tendencia a acumular una mayor cantidad de placa bacteriana, lo que conlleva a que haya un mayor riesgo de formación de cálculo, inflamación gingival, recesión gingival, caries lingual e interproximal, y enfermedad periodontal. Por eso, la mayoría de estudios resaltan como factor determinante la buena higiene oral para garantizar la salud periodontal y acudir a las citas control con el ortodoncista para evaluar el estado físico de la aparatología, a fin de evitar posibles fracturas o fallas en el sistema de adhesión de la contención fija y darle un tratamiento inmediato si esto ya hubiera ocurrido. La literatura no indica una técnica oral específica para los pacientes con contención fija posortodoncia, pero sí señala que se puede lograr una buena salud periodontal si el paciente mantiene una higiene oral adecuada y cómo el ortodoncista juega un rol importante motivando al paciente para lograrla.(AU)


The main objective following orthodontic treatment is to maintain long-term occlusal stability to avoid recurrence, and this is possible using post orthodontic fixed containment. The purpose of this study was to evaluate the different methods used for the control of bacterial plaque in patients with post orthodontic fixed containment and how these methods affect periodontal health status. There are many short- and long-term studies in this regard, but none have described negative effects. However, it is known that these patients tend to accumulate a greater amount of bacterial plaque, leading to a greater risk of calculus formation, gingival inflammation, gingival recession, lingual and interproximal caries, and periodontal disease. The refore, most studies have described good oral hygiene as the determinant factor for ensuring adequate periodontal health. They also report the need for patients to attend control appointments with their orthodontist to evaluate the state of the aprotology, avoiding possible fractures or failures in the adhesion system of the fixed retainer and receiving immediate treatment when this occurs. While the literature does not indicate a specific oral hygiene technique for patients with post orthodontic fixed containment, it does indicate that good periodontal health can be achieved if adequate oral hygiene is maintained and the important role orthodontists play in motivating the patients to achieve this.

RESUMO

Esta investigación se basa en la revisión de un tratamiento coadyuvante a la contención fija o removible postratamiento de ortodoncia para reducir la recidiva. La recidiva postratamiento de ortodoncia es un problema frecuente sobre todo en pacientes que tuvieron las piezas dentarias muy giradas o inclinadas, incluso en pacientes portadores de aparatos de contención fija o removible. Actualmente, se consideran a las fibras transeptales como causantes de las recidivas, especialmente las oxitalánicas por la posición que adoptan desde la unión cemento-adamantina de un diente hasta la misma unión del diente contiguo pasando sobre la cresta alveolar y por sus características elásticas. La fibrotomía circunferencial supracrestal (FCS) surge como una terapia coadyuvante para reducir las tasas de recidivas postratamiento de ortodoncia. El objetivo de la presente revisión de la literatura es describir el enfoque actual sobre la fibrotomía como terapia eficiente y estable a largo plazo para evitar la recidiva en los tratamientos de ortodoncia. La técnica quirúrgica no ha sufrido variaciones, pero sí han surgido autores que buscan realizar la FCS con diferentes instrumentos, tales como la electrocirugía y el láser de diodos de baja intensidad. A largo plazo, no existen diferencias significativas entre los diferentes instrumentos utilizados para la FCS comparados con la convencional, pero sí existen diferencias significativas entre realizar la FCS y no realizarla. La FCS es una terapia eficiente y estable sin importar el instrumento utilizado. (AU)


Post-orthodontic treatment relapse is a frequent problem, especially in patients who have very turned or inclined teeth, as well as in patients with fixed or removable devices. Currently, transeptal fibers are considered to cause relapses, especially oxitalic fibers because of the position they adopt from the cementoenamel junction of a tooth to the cementoenamel junction of the adjacent tooth passing over the alveolar crest and due to their elastic characteristics. Circumferential supracrestal fibrotomy (CSF) arises is increasingly used as an adjuvant therapy to reduce post-orthodontic treatment recurrence rates. The objective of the present review of the literature was to determine whether the current approach to fibrotomy is an efficient and stable long-term therapy to prevent recurrence in orthodontic treatments. Although the surgical technique has not undergone variations, some studies have sought to perform CSF with different instruments such as electrosurgery and low intensity laser diodes. In the long term there are no significant differences between the different instruments used for CSF compared to conventional CSF, but there are significant differences between performing or not this procedure. CSF is an efficient and stable long-term therapy regardless of the instrument used. (AU)
