RESUMEN

Orthodontic therapy could lead to marginal bone resorption in cases where the teeth are moved outside the envelope of bone. The purpose of this case series was to test corticotomy with a guided bone regeneration (GBR) procedure to regenerate bone in the direction of movement outside the original bony housing. Ten adult patients (60 anterior teeth), all presenting with severe anterior crowding, were enrolled in the study. Orthodontic therapy in all investigated sites was associated with selective surgical corticotomies and a simultaneous GBR procedure. CBCT examinations were performed before starting orthodontic treatment (T0) and at the end of treatment (T1; mean: 7 months; range: 6 to 9 months). Pre- and postoperative CBCTs were superimposed with a DICOM viewer (3D Slicer) and studied with an image-processing software (ImageJ, National Institutes of Health) to measure the area of interest of the buccal plate. The average area was found to be 0.58 ± 0.22 mm2 at T0 and 1.76 ± 0.4 mm2 at T1, with a statistically significant difference (P < .05). The combination of corticotomy and a regenerative procedure seems to have the ability to augment the original osseous anatomy when the root is moved outside of the original bony envelope.

RESUMEN

BACKGROUND: The aims of this bibliometric study were to determine author self-citation trends in high-impact orthodontic literature and to investigate possible association between self-citation and publication characteristics. METHODS: Six orthodontic journals with the highest impact factor as ranked by 2017 Journal Citation Reports were screened for a full publication year (2018) for original research articles, reviews, and case reports. Eligible articles were scrutinized for article and author characteristics and citation metrics. Univariable and multivariable negative binomial regression was used to examine associations between self-citation incidence and publication characteristics. RESULTS: Medians for author self-citation rate of the most self-citing authors and self-citations were 3.03% (range 0-50) and 1 (range 0-19), respectively. In the univariable analysis, there was no association between self-citation counts and study type (P = 0.41), article topic (P = 0.61), number of authors (P = 0.62), and rank of authors (P = 0.56). Author origin (P = 0.001), gender (P = 0.001) and journal (P = 0.05) were associated with self-citation counts and in the multivariable analysis only origin and gender remained strong self-citation predictors. Asian authors and females self-cited significantly less often than all other regions and male authors. CONCLUSIONS: Authors in orthodontics do not self-cite at a frequency that suggests potential citation manipulation. Author origin and gender were the only variables associated with citations counts. More bibliometric research is necessary to draw solid conclusions about author self-citation trends in orthodontic literature.

RESUMEN

In the domain of orthodontics, plaster models are contemplated as one of the important tools for diagnosis and treatment planning. In Dentistry, technological advancement has developed in the section of diagnostic devices, for example, the utilization of a 3D intraoral scanner, which can convert plaster models into digital models. With in-office utilization of this system, orthodontists can more meticulously and precisely construct custom braces, clear aligners, and orthodontic appliances. The digital data can be stored as a stereolithography file; it eliminates the disadvantages encountered with the storage of plaster models like breakage, space required, and distortion of the plaster models. ITero®element is the intraoral laser scanner (ILS) which utilizes parallel confocal scanning technology which maximizes the accuracy of the scan. By utilizing the iTero scanner, the dental measurement can be performed in OrthoCADTM software which is highly accurate. The objective of the contemporary study is to review the literature of studies on in-vivo and ex-vivo scanning with the iTero system.

RESUMEN

INTRODUCTION: This study aimed to evaluate market trends on the demographics most likely to select direct to consumer orthodontics and the reasoning behind their decisions. METHODS: An internet-based cross-sectional survey was conducted. Data analysis was carried out using logistic regression models. RESULTS: Total of 1573 surveys were completed. While 32.2% of those surveyed selected direct to consumer orthodontics over conventional orthodontics, 10.8% would select direct to consumer orthodontics for their children. Among parents who would seek direct to consumer orthodontics, only 27.8% would consider the same treatment for their children. The odds of seeking direct to consumer orthodontic treatment for divorced participants was 2.52 times higher than that for single participants, for participants with 4 children or more was 2 times higher than that for participant with no children, and in age group 46-59 years was 2.23 times higher than that for age group 18-26 years. Seventy three percent of consumers who selected direct to consumer orthodontics selected cost as an influencing factor. Convenience was also a major determining factor at 69.6%. CONCLUSIONS: Cost, convenience, and perceived simplicity all appear to factor into a consumer's consideration of direct to consumer orthodontics. As annual household income, age, and education increases consumers are more likely to consider direct to consumer orthodontic treatment.

RESUMEN

Easy Street is a fictional place where life is carefree. Many doctors and patients are finding simplified, less demanding treatments more appealing, especially in these infectious times that encourage approaches involving minimal contact. In orthodontics, the move to perform more clear aligner therapy may be a faulty step toward Easy Street. A case is made against further trivialization of our specialty.

RESUMEN

During the current pandemic scenario, maxillofacial rehabilitation specialists involved with supportive care in cancer must transform its practice to cope with COVID-19 and improve protocols that could quickly return the oral function of complex cancer patients who cannot wait for surgical complex rehabilitation. This includes the role of the maxillofacial prosthodontist for the rehabilitation of surgically treated patients with maxillary cancers by the means of filling obturator prostheses that are considered an optimal scientific-based strategy to reduce hospital stay with excellent pain control, oral function (speech, swallowing, mastication, and facial esthetics), psychologic and quality of life outcomes for the patients following intraoral cancer resection. Therefore, the aim of this commentary was to bring new lights to the strategic use of obturator prostheses for the rehabilitation of oral cancer patients during the COVID-19 pandemic as well as to present a protocol for managing such cases.

RESUMEN

BACKGROUND: The occurrence of an orofacial trauma can originate health, social, economic and professional problems. A 13-year boy suffered the avulsion of tooth 11 and 21, lost at the scenario. METHODS: Three intraoral appliances were manufactured: A Hawley appliance with a central expansion screw and two central incisors (1), trumpet edentulous anterior tooth appliance (2) and a customized splint (3) were designed as part of the rehabilitation procedure. Objectively assessing the sound quality of the trumpet player with these new devices in terms of its spectral, temporal, and spectro-temporal audio properties. A linear frequency response microphone was adopted for precision measurement of pitch, loudness, and timbre descriptors. RESULTS: Pitch deviations may result from the different intra-oral appliances due to the alteration of the mouth cavity, respectively, the area occupied and modification/interaction with the anatomy. This investigation supports the findings that the intra-oral appliance which occupies less volume is the best solution in terms of sound quality. CONCLUSIONS: Young wind instrumentalists should have dental impressions of their teeth made, so their dentist has the most reliable anatomy of the natural teeth in case of an orofacial trauma. Likewise, the registration of their sound quality should be done regularly to have standard parameters for comparison.

RESUMEN

BACKGROUND: The aim is to demonstrate the validity of the monitoring through intraoral scanner of the dental movements and the real impact, advantages, and convenience, in terms of treatment time and efficiency gain, to frequently monitor a patient with the scanner application. METHODS: A movement control of palatally impacted canines was performed, surgically treated with laser opercolectomy. Three-dimensional models of the patient's dental arch were obtained with intraoral scanner during a monitoring time of 4 months. The STL (Standard Triangle Language) files were superimposed with the 3D models extrapolated from the pre-operative CT (Computerized Tomography). The measurements of eruption, exposed palatal and vestibular areas, and distances between the canines and the incisors were performed, using digital technologies and with a digital caliber. RESULTS: Descriptive and inferential statistical analysis of the data obtained from both conventional and digital monitoring has been realized and performing the T Student Test for paired data. CONCLUSION: The advantages of digital monitoring are numerous, like the possibility to reduce the error of method caused by manual measurement on plaster casts and the possibility to compare the pattern and amount of eruption of the canine in the same patient overtime.

RESUMEN

OBJECTIVES: To investigate content of orthodontic-related videos on YouTube to improve the understanding of orthodontic patients' perceptions and treatment experiences. MATERIALS AND METHODS: A systematic search was conducted on YouTube on March 20, 2018, and updated on August 4, 2019, to identify all relevant videos using search terms "orthodontic," "orthodontics," "braces," and "orthodontic braces." The data set was captured from YouTube Data API (Application Programming Interface) and stored in an Excel database using a query function written in Python. All videos captured were viewed and categorized by three independent dental investigators using thematic analysis. The top 100 videos (by view count) related to patients' treatment experience were further analyzed using discourse analysis. RESULTS: A total of 600 orthodontic videos were screened, and 546 were included in the study. Six main themes were identified: (1) individual review of orthodontic treatment (45.8%, n = 250), (2) entertainment (19.8%, n = 108), (3) education (18.3%, n = 100), (4) advertisements (6.6%, n = 36), (5) time lapse of orthodontic treatment (5.3%, n = 29), and (6) do-it-yourself orthodontics (4.2%, n = 23). Of the top 100 videos related to patient's individual review of treatment, patients' main focuses were on pain (24%), problems with chewing and swallowing (12%), and adhesive removal (10%). CONCLUSIONS: Orthodontic-related YouTube videos are diverse in nature. The most common video category was video providing an individual review of orthodontic treatment experience. Other popular video categories included entertainment, education, and advertisements. A range of do-it-yourself YouTube videos were also identified. YouTube may provide an opportunity for orthodontic professionals to disseminate health information.

RESUMEN

OBJECTIVES: To compare the effect of various degrees of decalcification after orthodontic treatment (white spot lesions) on orthodontists', general dentists', and laypersons' ratings of smile esthetics. MATERIALS AND METHODS: Eight photographs representing incrementally altered tooth decalcification lesions of maxillary anterior teeth ranging from mild to severe were shown randomly to the study participants. Photographs were rated by a matched sample of orthodontists (N = 42), general dentists (N = 52), and laypeople (N = 58). A visual analogue scale (VAS) was used to assess perceptions of smile esthetics. RESULTS: The three groups of raters could distinguish between different decalcification levels. Raters gave more negative scores as the decalcification level increased. CONCLUSIONS: The three groups of raters were able to distinguish between various degrees of decalcification lesions. General dentists were the most critical of all groups when rating decalcification lesions.

RESUMEN

By means of an online questionnaire, the opinions of dental health practitioners on 'orthodontics' were assessed on the basis of 10 statements. There were 523 responses, 51% of which were from general practitioners, a relatively large number from orthodontists (31%) and 18% from other dental health practitioners. Concerning indication of treatment, dental health prior to treatment and the value of straightened teeth, opinions were clearly positive, somewhat more among orthodontist than among general practitioners. Patients knowledge concerning orthodontics and the negative side of orthodontics and their trust in the durability of orthodontic retention are all considered to be more positively present in patients by orthodontists than general practitioners. 1 in 3 non-orthodontists considered carrying out orthodontic procedures in the general practice to be fine. More than 90% of orthodontists disagreed. Female dental practitioners more often consider orthodontic treatment to belong with an orthodontist. The number of women was equally divided across the different groups.

RESUMEN

The first publication on the use of magnets in dentistry for stabilizing prosthetics on implants dates back to 1953. Clinical development in orthodontics, without having experienced a real boom, has increased over the past ten years, in parallel with the improvement of the device. The objective of this review of the literature is to synthesize clinical applications and reported iatrogenic effects. A systematic review of the international literature from the Pubmed and Cochrane databases from 1999 to July 2018 was conducted which resulted in 36 articles. The factors studied are the indications and contraindications, the means or procedure, as well as the iatrogenic effects. Original cases are presented. The correction of infraclusions is the main indication, followed by the correction of anteroposterior malocclusions and then the correction of over-erupted teeth. Traction of an impacted teeth and diastema closure have not been found in recent publications probably because of the low benefit-risk ratio. The future no longer seems to be buried magnets or left in the long term in the mouth considering there seems to be concerns in terms of toxicity (or even the risk in terms of vital prognosis). The magnets could offer interesting perspectives to manage the current limits of the aligners, the movements of anterior egression, rotation and previous torque being still problematic...

RESUMEN

The fusion of orthodontic treatment and periodontal tissue-regeneration therapy has attracted attention. However, regenerated bone has a higher density than physiologic bone, which may cause problems including root resorption or stagnation of orthodontic movement. Therefore, the optimized periodontal regeneration for orthodontic movement (O-PRO) approach was developed with the aim of regenerating periodontal tissues with sparse bone quality. Unlike conventional methods, this concept is specifically suited for orthodontic movement. A new classification for the preoperative evaluation of periodontal tissues was also devised, and results are reported from cases where orthodontic treatment was implemented using each type of O-PRO method.

RESUMEN

In 2018, a new « Classification of Periodontal and Peri-implant Diseases and Conditions ¼ was adopted by the American Academy of Periodontology and the European Federation of Periodontology. Numerous studies in recent years have improved the understanding of periodontal diseases and their risk factors, leading to an update of the 1999 classification. Among the major changes is the development of a classification of periodontitis into different stages and grades and the notion of periodontal health, an essential prerequisite for orthodontic treatment. Based on the analysis of the 24 published articles, this work provides explanations regarding the main changes that orthodontists may face. The classification of Chicago precisely defines periodontal health and proposes a new system for characterizing periodontitis in stages and grades. It then becomes a valuable aid for the orthodontist in risk detection and periodontal screening. The knowledge of this new classification is essential for reliable communication between dentists, periodontists and orthodontists, in order to guarantee the success of orthodontic treatment.

RESUMEN

For several decades, orthodontists and periodontists have repeated that orthodontics have no harmful consequences on the periodontium when it is healthy or treated. However, a systematic review of the literature undermines this common refrain and concludes that there is a lack of reliable evidences of the positive effects of orthodontics on periodontal health with, in the best periodontal conditions, slight adverse effects. It is therefore the responsibility of orthodontists to keep the periodontal cost of orthodontic treatment as low as possible. How to make sure that this « at best ¼ does not turn into an « at worst ¼ ? In order to minimize the deleterious consequences of orthodontic treatment on the periodontium, the orthodontist must be able to specify which patients she/he can immediately consider providing orthodontic treatment and those on whom periodontal treatment is mandatory before all. The orthodontist must therefore transform, for a few minutes, into a periodontist in order to recognize the eight signs of loss of attachment and the six risk factors for periodontitis, exposed in this article. Both needs for periodontal and orthodontic treatment have to be measured and would not be efficient without the patient's and the practitioners' motivation.

RESUMEN

The objective of this comparative retrospective cohort performed on 202 patients was to evaluate the influence of instrumental extraction (forceps, suction cup, spatula) during delivery on the need for orthodontic treatment. Questionnaires on the type of delivery were distributed in three different structures. The need for treatment was assessed using the IOTN indicator (Index of Orthodontic Treatment Need). The groups were compared by statistical tests at the significance level of 5 %. 202 patients were included (51 in the group « instrumental delivery ¼, 151 in the control group). With an average IOTN of 3.3 in the « instrumental delivery ¼ group versus 2.5 in the « non-instrumental delivery ¼ group, the difference between the two groups is statistically significant (p = 0.00015). Since the need for orthodontic treatment is significantly higher in patients born by instrumental delivery compared to patients born without instrumental support, instrumental extraction is therefore a risk factor in orthodontics, diagnosis and orthodontic treatment may be indicated in these patients. In addition, provided that it is proven effective, early osteopathic management may be recommended.

RESUMEN

The aim of this study was to describe a surgical technique that can be used to solve dentofacial deformities in cleft palate patients with maxillary hypoplasia in order to increase maxillary alveolar bone width, without modifying the skeletal base, and therefore, keeping the velopharyngeal function unaltered. Four patients with a history of cleft palate not associated with syndrome and treated under conventional surgical protocol during their childhood, underwent PAOO surgery incorporating L-PRF, followed by an accelerated orthodontic treatment with checkups every two weeks. All patients reached the desired occlusion without modifying their skeletal bases and velopharyngeal function. Orthodontic treatments were finished between 10 and 14 months after surgery without complications. There were no observed complications in the velopharyngeal postsurgical function and an increase in the arch width was achieved in all cases, along with a reduced orthodontic treatment time. The clinical results obtained confirm that PAOO technique is a safe and reliable complement to orthognathic surgery in the surgical treatment of cleft patients. By increasing the perimeter of the maxillary dentoalveolar ridge, the segmentation of the maxilla could be avoided, increasing the post operatory stability of these patients.

RESUMEN

INTRODUCTION: During the decision-making process, physicians rely on heuristics that consist of simple, useful procedures for solving problems, intuitive shortcuts that produce reliable decisions based on limited information. In clinical situations characterized by a high degree of uncertainty such as those encountered in orthodontics, cognitive biases and judgment errors related to heuristics are not uncommon. This study aimed at promoting trust in the effective interface between the intuitive reasoning of the orthodontic practitioner and the computational heuristics emerging from simple statistical models. METHODS: We propose an integrative model based on the interaction between clinical reasoning and 2 computational tools, cluster analysis and fast-and-frugal trees, to extract a structured craniofacial representation of untreated subjects with Class III malocclusion and to forecast the worsening of the malocclusion over time. RESULTS: Cluster analysis of cephalometric values from 144 growing subjects with Class III malocclusion followed longitudinally (T1: mean age, 10.2 ± 1.9 years; T2: mean age, 13.8 ± 2.7 years) produced 3 morphologic subgroups with predominant sagittal, vertical, and slight maxillomandibular imbalances. Fast-and-frugal trees applied to different subgroups extracted heuristics that improved the prediction of key features associated with adverse craniofacial growth. CONCLUSIONS: Provided that cephalometric values are placed in the appropriate framework, the matching between simple and fast computational approaches and clinical reasoning could help the intuitive logic, perception, and cognitive inferences of orthodontic practitioners on the outcome of patients affected by Class III disharmony, decreasing errors associated with flawed judgments and improving the accuracy of decision making.
