INTRODUCTION:
Orthodontics has gone through remarkable advances for those who practice it with dignity and clinical quality, such as the unprecedented number of patients treated of some type of iatrogenic problems (post-treatment root resorptions; occlusal plane changes; midline discrepancies, asymmetries, etc). Several questions may raise useful reflections about the constant increase of iatrogenics. What is causing it? Does it occur when dentists are properly trained? In legal terms, how can dentists accept these patients? How should they be orthodontically treated? What are the most common problems?
OBJECTIVE:
This study analyzed and discussed relevant aspects to understand patients with iatrogenic problems and describe a simple and efficient approach to treat complex cases associated with orthodontic iatrogenics.

UNLABELLED
Orthodontic retention is the final important stage of orthodontic treatment, the aim of which is to consolidate the functional and aesthetic position of teeth. Among adults, fixed retainers made of different types of wires are the most common. The aim of this study was to analyse the mechanical properties of a new generation of fixed orthodontic retainers-printed by 3D printers.
MATERIALS AND METHODS
The study was conducted using samples made of Nextdent MFH C&B N1 resin in the form of cuboid bars with nominal dimensions of width b = 3 mm, thickness d = 0.8 mm; 1 mm; 1.2 mm, length l = 30 mm for each type. The influence of the thickness of the retainers on their strength under loaded conditions was evaluated. Flexural strength, elastic properties, deflection, and creep were compared. The samples were aged in an artificial saliva bath at 37 ± 1 °C during the strength tests.
RESULTS
It was shown that differences in the thickness of the samples affected their elastic and strength properties. The highest average flexural modulus, the highest deflection, creep, and strength was characteristic of the samples with the highest thickness (1.2 mm). Samples with an average thickness of 1 mm had the lowest modulus of elasticity.
CONCLUSIONS
The mechanical properties of 3D printed retainers show that they can be an alternative to metal retainers and the procedure of making new retainers, especially when patients have aesthetic requirements or allergies to metals.

Journal of Orthodontics Mar 2022To identify the number of companies providing Do-It-Yourself (DIY) orthodontics and explore information available on websites for DIY brace providers operating in the UK.
OBJECTIVE
To identify the number of companies providing Do-It-Yourself (DIY) orthodontics and explore information available on websites for DIY brace providers operating in the UK.
DESIGN
Web search and review of websites providing DIY braces.
SETTING
Leeds, UK.
METHODS
A Web search was completed in November 2020 and April 2021 of all companies providing DIY braces for UK consumers. Each website was evaluated, and the following data collected: name; year started operating; costs; process; involvement of a dental professional; average 'treatment' length; retention; consent process; information on risks and benefits; aligner material; social media presence; age suitability; and consumer ratings on Trustpilot. Quality of website information was assessed via the DISCERN tool.
RESULTS
Seven DIY orthodontic companies were operating in the UK. Websites reviewed revealed the following: product costs were in the range of £799-£1599, 'treatment' length quotes were in the range of 4-12 months; Trustpilot reviews were in the range of 1.6-4.8 stars; and websites claimed their aligners were suitable for individuals with an age range of 12-18 years. Quality of content regarding risks described on websites varied, and there was limited information regarding involvement of a dental professional. Quality of websites information scored 'poor' or 'very poor' on the DISCERN scoring.
CONCLUSIONS
There has been an increase in the number of DIY orthodontic companies operating in the UK over the last three years. There is a need to determine whether these products constitute dental treatment in their own right. If so, it is crucial to ensure these are regulated appropriately with adequate information available to satisfy informed consent and have greater transparency over dental professional involvement to safeguard the public.

Meta-Analysis Review
BACKGROUND
Smile attractiveness is a primary factor for patients to seek orthodontic treatment, however, there is yet no systematic evaluation of this topic in the literature.
OBJECTIVES
To assess the current evidence on the effect of orthodontic treatment on smile attractiveness.
SEARCH METHODS
Seven electronic databases (MEDLINE, Cochrane Library, Virtual Health Library, SCOPUS, Web of Science, Google Scholar and Embase) were searched on 14 September 2022.
SELECTION CRITERIA
Studies evaluating smile attractiveness before and after orthodontic treatment or only after completion of orthodontic treatment.
DATA COLLECTION AND ANALYSIS
Extracted data included study design and setting, sample size and demographics, malocclusion type, treatment modality and method for outcome assessment. Risk of bias was assessed with the ROBINS-I tool for non-randomised studies. Random-effects meta-analyses of mean differences and their 95% confidence intervals (CIs) were planned a priori.
METHODS
After elimination of duplicate studies, data extraction and risk of bias assessment according to the Cochrane guidelines, an evaluation of the overall evidence was performed. The included studies were evaluated based on the characteristics of their study and control groups and based on their main research question. Also, all outcome measures were standardized into a common assessment scale (0-100), in order to obtain more easily interpretable results.
RESULTS
Ten studies were included in this review, nine of which were assessed as being at serious risk of bias and one at moderate risk of bias. The large heterogeneity between the included studies did not allow for a meta-analysis. Orthodontic treatment has a moderately positive effect on smile attractiveness. When compared to no treatment, orthodontic treatment with premolar extractions improves smile attractiveness by 22%. Also, surgical correction of Class III cases increases smile attractiveness by 7.5% more than camouflage treatment. No other significant differences were shown between different types of treatment.
CONCLUSION
Based on the available data, orthodontic treatment seems to moderately improve the attractiveness of the smile. There is significant bias in the current literature assessing the effect of orthodontics on smile attractiveness; therefore, the results cannot be accepted with certainty.

Review
Self-ligating brackets have enjoyed recent popularity in the orthodontic marketplace with various claims made including faster ligation, lower friction, faster treatment, less pain, waking up the tongue, and fewer appointments. Although various designs of self-ligating brackets have been available for many years they have only recently surged in popularity on the back of these claims but what evidence is there to support these claims? This review article examines the current available evidence regarding treatment duration, influence on archform, and the speed of tying and untying self-ligating brackets compared with conventional brackets and methods of ligation.

Review
For complex implant cases, simple implantation could not achieve the desired therapeutic effect, and a multidisciplinary approach has become a general trend. Orthodontic treatment before implantation creates favorable conditions for subsequent implantation by increasing restoring three-dimensional space, improving occlusion of patients. It also stimulates the increase of autologous soft and hard tissue while biological potential of periodontal ligament is fully developed. The choice of operation time is vital to keep the level of soft and hard tissue at the implantation site, which improves the curative effect of implantation in terms of function and aesthetics. In this article, the orthodontic-implant combined therapy is briefly reviewed focusing on the three-dimensional space optimization, implant site enhancement by orthodontic extrusion and delayed orthodontic space opening.

The genius of Edward Hartley Angle, (1855-1930), the founder of the dental specialty of orthodontics, to create order from chaos in the study and treatment of positional discrepancies of the teeth, jaws and face advanced greatly the cause of dental public health. Angle's innovations that had the most public health impact were (1) his identification of dental occlusion, not simply tooth irregularity, as a prime concern, (2) his development of an uncomplicated classification system for occlusal conditions, (3) his introduction of prefabricated orthodontic appliances and (4) his framing of orthodontics as a dental specialty by organizing the world's first educational program to train orthodontists.

Meta-Analysis Review
BACKGROUND
Anterior open bite occurs when there is a lack of vertical overlap of the upper and lower incisors. The aetiology is multifactorial including: oral habits, unfavourable growth patterns, enlarged lymphatic tissue with mouth breathing. Several treatments have been proposed to correct this malocclusion, but interventions are not supported by strong scientific evidence.
OBJECTIVES
The aim of this systematic review was to evaluate orthodontic and orthopaedic treatments to correct anterior open bite in children.
SEARCH METHODS
The following databases were searched: the Cochrane Oral Health Group's Trials Register (to 14 February 2014); the Cochrane Central Register of Controlled Trials (CENTRAL)(The Cochrane Library 2014, Issue 1); MEDLINE via OVID (1946 to 14 February 2014); EMBASE via OVID (1980 to 14 February 2014); LILACS via BIREME Virtual Health Library (1982 to 14 February 2014); BBO via BIREME Virtual Health Library (1980 to 14 February 2014); and SciELO (1997 to 14 February 2014). We searched for ongoing trials via ClinicalTrials.gov (to 14 February 2014). Chinese journals were handsearched and the bibliographies of papers were retrieved.
SELECTION CRITERIA
All randomised or quasi-randomised controlled trials of orthodontic or orthopaedic treatments or both to correct anterior open bite in children.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed the eligibility of all reports identified. Risk ratios (RRs) and corresponding 95% confidence intervals (CIs) were calculated for dichotomous data. The continuous data were expressed as described by the author.
MAIN RESULTS
Three randomised controlled trials were included comparing: effects of Frankel's function regulator-4 (FR-4) with lip-seal training versus no treatment; repelling-magnet splints versus bite-blocks; and palatal crib associated with high-pull chincup versus no treatment.The study comparing repelling-magnet splints versus bite-blocks could not be analysed because the authors interrupted the treatment earlier than planned due to side effects in four of ten patients.FR-4 associated with lip-seal training (RR = 0.02 (95% CI 0.00 to 0.38)) and removable palatal crib associated with high-pull chincup (RR = 0.23 (95% CI 0.11 to 0.48)) were able to correct anterior open bite.No study described: randomisation process, sample size calculation, there was not blinding in the cephalometric analysis and the two studies evaluated two interventions at the same time. These results should be therefore viewed with caution.
AUTHORS' CONCLUSIONS
There is weak evidence that the interventions FR-4 with lip-seal training and palatal crib associated with high-pull chincup are able to correct anterior open bite. Given that the trials included have potential bias, these results must be viewed with caution. Recommendations for clinical practice cannot be made based only on the results of these trials. More randomised controlled trials are needed to elucidate the interventions for treating anterior open bite.
