Background:
Facial patterns or biotypes have been known to influence the treatment plan of orthodontic patients and analyze the facial patterns described by Ricketts. Determining the facial type is extremely important for orthodontic diagnosis and planning since the muscular and skeletal configuration of each facial type responds differently to the orthodontic treatment.
Materials and Methods:
A sample of 100 individuals was recruited by multistage sampling from three schools in Ikeja local government, Lagos State. Those aged between 12 and 16 years who met the inclusion criteria were enrolled in the study after obtaining informed consent and assent from the parents and participants. Lateral cephalometric radiographs were taken for all participants, and the final sample after analysis of the radiographs was 84. The error of the cephalometric method was assessed using the intraclass correlation coefficient. Facial axis angle (Ptm-Gn/Ba-N) was used to classify the facial pattern into brachyfacial (<87°), mesofacial (87°–93°), and dolichofacial (>93°)
Results:
Out of the 84 participants, 60 (71.4%) had mesofacial facial pattern which consisted of 27 (32.1%) males and 33 (39.3%) females. 10 (11.9%) had brachyfacial pattern out of which 9 (10.7%) were male and 1 (1.2%) was a female. This difference between the males and females in the brachyfacial pattern was statistically significant with a P value of 0.014 (P ≤ 0.05). 14 (16.67%) participants had dolichofacial pattern with 5 (6.0%) males and 9 (10.7%) females.
Conclusion:
The mesofacial pattern had the highest frequency among the facial pattern types studied in this Nigerian population and was found to be more predominant among females. The brachyfacial pattern was seen more frequently in males while the dolichofacial pattern was more prevalent among females. The facial pattern assessment should guide the orthodontist in the use of appropriate mechanics to achieve an overall balanced occlusion and facial profile following orthodontic treatment.

Abstract:
Periodontally accelerated osteogenic orthodontics (PAOO) is a combination of a selective decortication facilitated orthodontic technique and alveolar augmentation. With this technique, one is no longer at the mercy of the preexisting alveolar volume, and teeth can be moved two to three times further than required for traditional orthodontic therapy. It is used to treat moderate-to-severe malocclusions in both adolescents and adults. PAOO technique increases alveolar volume which can provide a more intact periodontium, inturn decreases need for extractions, increases a degree of facial reshaping. This technique also increases the bony support for both the teeth and the overlying soft tissues. Here is a case report which highlights the above-mentioned uses with PAOO technique in a severe periodontally compromised Class II division1 malocclusion patient treated with nonextraction line of orthodontic treatment.

Abstract:
Maintaining the achieved occlusion following the orthodontic treatment is the most difficult task of the entire treatment process. Relapses are common in noncompliant patients and in some cases despite the patient following the protocol. There are various factors for the relapse after the orthodontic treatment. The relapsed malocclusions can be corrected by simple procedures such as composite buttons. They are economical and esthetic considering the relapsed space. A 27-year-old female patient presented to our orthodontic department with the chief complaint of mild anterior spacing with midline diastema and anterior crossbite in relation to 21, after treatment with fixed appliance therapy. The patient was treated with composite buttons, and satisfactory results were obtained. Composite buttons are an alternate treatment line for mild relapsed cases in patients who are not willing to undergo the fixed appliance therapy again.

Abstract:
The prediction of orthognathic treatment is an important part of treatment planning. The manual method of prediction tracing by Epker and Fish had been the gold standard in planning for orthognathic cases. Because it was time-consuming, hence computerized methods gained the popularity. A 19-year-old boy reported with a chief complaint of forwardly placed lower jaw and poor smile for the past 2 years. Examination revealed the mandibular prognathism, obtuse nasolabial angle, posterior cross bite with reverse overjet of 1 mm–0.5 mm of overbite, and bilateral Class III molar and canine relation. There was also the deviation of 1.5 mm midline to left present. On the basis of findings, a diagnosis of mandibular prognathism was made. Treatment planning included an orthognathic surgery (Bilateral sagittal split osteotomy) for the mandibular setback. For the surgical procedure, both manual and computerized methods of prediction were done. Both tracing methods result was same and recommended the mandibular setback of 5 mm.

Abstract:
This case report describes the orthodontic treatment of an 18-year-old male patient who presented with straight profile, tongue thrust habit, proclined upper incisors, generalized spacing in the upper and lower arches, Katz Class II premolar relation unilaterally, and Class II canine relation unilaterally with increased overjet and overbite. A butterfly system was used for the treatment combined with frictionless biomechanics in the initial stage of the treatment followed by continuous arch mechanics in the later part of the treatment. A tongued crib was used to stop the tongue thrust habit along with one elastic swallow exercise. Micro-implant anchorage was used unilaterally in the upper arch for retraction of the entire segment and correction of the unilateral Class II canine and premolar relationship. To avoid a dished-in profile, a nonextraction treatment was executed. Final correction of distally tipped canines was achieved using conventional Begg's uprighting auxiliaries in the vertical slots of the butterfly system in the finishing stage. The case was finished using bite-settling elastics. The total treatment time was 1 year and 2 months. Esthetic and functional goals were achieved satisfactorily with proper selection of biomechanics.

Abstract:
Since 1930s Class II malocclusion benefits from functional appliances. These appliances alter the arrangement of various muscle groups to correct the position of mandible to grow out of the skeletal disharmony. These appliances have been broadly divided into removable and fixed functional appliances. Fixed functional appliances also known as “noncompliant Class II correctors” have gained significant ground in the last few years. With them in use, the treatment duration is reduced by 6 months. They are divided into rigid, flexible, and hybrid appliances. Rigid fixed functional appliances restrict the mandibular movements and flexible fixed functional appliances have frequency of breakage to a greater extent. To overcome these drawbacks, hybrid fixed functional (HFF) appliances have come into play. HFF appliances offer the advantages of previous ones, thus eliminating their pitfall. Recent advances have also lead to the improvisation with the use of HFF appliances. This review article provides the gist of different HFF appliances till date with their considerations in use, mode of action, biomechanical effects, and advances in this field.

Abstract:
Background:
Retention is considered as an important phase at the end of any active orthodontic tooth movement.
Aims:
The purposes of this study were to compare compliance between Hawley retainer (HR) and vacuum formed retainers (VFRs) and to detect the reasons for noncompliance.
Materials and Methods:
Questionnaires were distributed to those who had an orthodontic treatment and currently have experience with the orthodontic retainer. Items included demographic information and questions pertaining to treatment satisfaction, perceived responsibility for retention, type of retainer prescribed, Likert scale to detect the reasons for discontinuing use of retainers, and relapse. Chi-square and t-test were used to compare the data.
Results:
Out of the 150 questionnaires distributed, 98 returned and seven were excluded from the study. The compliant groups were 40, whereas the noncompliant group were 51. Sixty-four (70.3%) of the participants were using HR, whereas 27 (29.7%) were using VFRs retainer. Seventeen percent (Hawley) and 15% (VFRs) of the participants who did not comply reported that they had lost their retainer. For both retainers, those participants who did not comply, the majority agreed that they do not wear their retainer because it affects their eating (84.3%), speech (56.9%), comfort (47.1%), and breath odour (43.1%). A statistically significant difference in compliance levels in relation to the length of time since debond was also found (P < 001).
Conclusions:
The participants were more compliant with Hawley's than VFRs retainers and a significant difference in compliance levels in relation to the length of time since debond was found.

Abstract:
Aim:
The purpose of this investigation was to establish an equation for the prediction of the size of unerupted canines and first and second premolars in a Qatari population.
Materials and Methods:
In this study, dental casts of 100 Qataris (50 males and 50 females) were selected. The participants' age ranged from 15 to 20 years. The width of all permanent teeth with the exception of second and third molars was measured. The data were subjected to Student's t-test and regression analysis.
Results:
The results indicated that 15%, 25%, and 35% confidence levels were more accurate determinants of the unerupted canines and premolars than the commonly used 75% level of Moyers when both sexes were combined. The multiple regression equations revealed different confidence levels for males and females. Tanaka and Johnston's equations overestimate the predicted tooth width of the unerupted canine and first and second premolars.
Conclusions:
Three levels of confidence were found to be more accurate in the maxillary arch and two in the mandibular arch when compared to the commonly used 75% in Moyers' table when both sexes were combined. Therefore, three new equations for maxillary and mandibular arches are proposed to predict the size of unerupted canine and first and second premolar teeth for Qatari males and females and for both sexes combined.

Abstract:
Background:
Impacted upper central incisors substantially affect esthetics, function, and the self-esteem of patients. This retrospective multicenter study was designed to assess and compare the demographic and radiographic features and treatment findings for patients with impacted upper central incisors in three different countries.
Materials and Methods:
Diagnostic and treatment records, panoramic radiographs, and lateral cephalograms were retrieved for 74 (32 female) patients (11.24 ± 2.9 years old), with impacted upper central incisors from the USA, Germany, and Colombia, according to the preset eligibility criteria. Sagittal and vertical angulation and location of the upper impacted central incisors, type of radiographic skeletal malocclusion, surgical procedures, and duration of treatment were investigated.
Results:
Statistically significant differences between the three groups were found for age (P = 0.003), duration of treatment (P = 0.001), and location of the impacted upper central incisors (P = 0.015). The angulation was significantly bigger for the impacted central incisors compared to the respective normal incisors (P < 0.0001). The age of the patients did not influence the treatment time. The regression model showed that higher height of impaction was associated with a closed surgical procedure (P = 0.046).
Conclusions:
Patients with impacted incisor treated in three different centers showed differences in terms of age, gender, treatment time, and type of surgical treatment. The surgical access with closed surgery has a direct relationship with a more apical location of the impacted incisor.

Abstract:
Replacement of missing teeth in growing children is one of the challenges an orthodontist encounters. Removable partial denture or resin-bonded fixed denture can be considered as replacement options, but they promote alveolar bone loss due to lack of alveolar loading. Removable denture is undesirable as adolescents are self-conscious in revealing the edentulous space while eating. Resin-bonded fixed denture compromise alveolar and gingival contours. Dental implants are not placed in growing children due to remaining growth. Orthodontic miniscrews can be efficiently used for interim restoration before skeletal growth. The current article presents a case report of miniscrew-assisted interim tooth pontic.

Stem cell (SC) therapy has become a buzz word in several debilitating diseases in medicine. This rapidly evolving cutting-edge technology has slowly extended its tentacles in dentistry without sparing orthodontics. There are several conditions in orthodontics which are only being partly answered by human-engineered techniques. With the hope of getting a complete solution to several such problems, research in SC therapy has gained momentum in orthodontics for the past few decades. Electronic databases were searched for the material collection; language restriction was not followed. The following keywords were used: stem cell and orthodontics. The search was not limited to any particular type of study design. This review article describes various possible areas in orthodontia where SC therapy will and can be applied in future based on the evidence from a collection of several such studies conducted in those areas.

Abstract:
The increasing usage of smartphones is rapidly changing our lives both personally and professionally. In healthcare and dentistry, various apps are accessible on the smartphone to educate patients about orthodontics and help them through their treatment. Also, various apps are available for the orthodontist to manage patients and to update oneself on the current modalities of treatment. The aim of this article was to review the various apps available on the iOS Apple Store and Google Play Store for patients and orthodontists. Two smartphones were used to search for apps using keywords such as orthodontics, orthodontist, braces specialists, and braces. A total of 354 apps relevant to orthodontics were found on both the iOS and Android platforms. These apps could be classified as patient education apps, patient management apps, diagnostic apps, and updating apps.

Objective:
Comparative evaluation of Tweed's analyses in Class I, Class II, and Class III participants of Central India in two different age groups.
Materials and Methods:
Sample size comprised 240 participants belonged to Central India. Participants were divided into two main groups: Group I comprised 120 young children in the age group of 12–16 years and Group II comprised 120 young adults in the age group of 18–22 years. Tweed's analysis was performed from the collected sample.
Results:
The lower incisor inclination (incisor-mandibular plane angle [IMPA]) in Central India participants was higher (100.13°) compared to the original Tweed norm of IMPA 90°. Statistically higher value of IMPA was found in young male children compared to young female children in Class II div 1 and Class II div 2 participants and opposite trend was seen in Class III young adults. The Frankfort-mandibular plane angle was found to be significantly more in young adult females (24.93°) than males (18.07°) in Class III participants. Angle IMPA was found to be significantly higher in Class I compared to Class III participants and significantly higher in Class III compared to Class II div 2 participants.
Conclusion:
The differences of Tweed's parameters in this pilot study indicate that Caucasian norms cannot be truly adhered to Central India participants during orthodontic treatment. Lower incisors were normally more proclined in Central Indian participants and their over retraction during orthodontic treatment would cause prominent chin. Proclination of lower incisor was more in young male children compared to young female children in Class II div 1 and Class II div 2 participants and opposite trend was seen in Class III young adults. Class III female adults show tendency toward vertical growth pattern compared to males. Proclination of lower incisor was found to be more in Class I compared to Class III participants and more in Class III compared to Class II div 2 participants.

The aim of this study was to determine appropriate range of cortical bone thickness (CBT) to adequately support microimplants and optimum force magnitude on microimplants for minimal stress distribution.
Settings and Design:
Three-dimensional (3D) CAD models of the desired implant features and cylindrical bone piece of desired height and thickness were exported to FEA software, and variable load was applied on range of different CBT to determine the compressive radial stress and maximum failure load.
Subjects and Methods:
it is clearly said that CBT of various thickness which will represent human maxilla and mandibular bone. The force magnitudes ranging from 15 g to 150 g (in range of 15 g, 50 g, 85 g, and 150 g) were taken to simulate typical orthodontic forces loaded onto microimplant.
Statistical Analysis Used:
Statistical data were analyzed by IBM SPSS Statistics for windows Version 20.0 (IBM Corp., Armonk, NY, USA) software. For quantitative data analysis, ANOVA test was used.
Results:
For CBTs of 0.5, 1.5, 2.5, and 3.0 mm, the maximum force magnitudes that could be applied safely were 533.7, 551.7, 552.3, and 552.9, respectively. Even though there was no difference statistically, the amount of displacement for CBT 1.5–3.0 mm is comparatively less than for 0.5 mm. CBT value of 1.5–3.0 mm might be appropriate for microimplant stability.
Conclusions:
For the purpose of diminishing orthodontic microimplant failure, an optimal force that can be safely loaded onto a microimplant should not exceed a value of around 533–553 g. The CBT of 1.5–3.0 mm might be considered appropriate for the stability of microimplant.

Background:
Early orthodontic treatment (EOT) aims at identifying and intervening occlusal conditions in primary and early-mixed dentition.
Aim:
This study aimed at assessing EOT need and its relationship with sociodemographic characteristics using the index for preventive and interceptive orthodontic treatment needs (IPION) among schoolchildren in Dar es Salaam, Tanzania.
Study Setting and Design:
An analytical cross-sectional study was conducted among schoolchildren aged 6 and 9 years.
Materials and Methods:
Schoolchildren were selected by multistage cluster sampling technique. Questionnaires were used to obtain sociodemographic information; clinical examinations were done to record schoolchildren's IPION scores.
Statistical Analysis Used:
Data were analyzed using a computer software, SPSS version 20.0. Chi-square test was used for assessing statistical differences between variables; P value was set at P < 0.05.
Results:
A total of 667 schoolchildren were involved (59.5% girls; 52.5% 9-year-olds). In 6-year-olds, 77.9% had caries, and in 9-year-olds, 60% had caries. Lower-second primary molars were the most common prematurely lost teeth. Increased overjet was the most frequently recorded occlusal anomaly. Many 9-year-old boys than girls had caries (67.4% vs. 55.5%, P = 0.032). Six-year-olds with mothers who were homemakers compared to those with employed mothers experienced caries (81.7% vs. 71.0%, P = 0.034). Overall, 67.2% and 41.7% of the participants had EOT need and definite EOT need, respectively.
Conclusion:
EOT need for malocclusions was high in the involved school children, these will thus benefit from preventive and interceptive orthodontic treatment programs.

In the article titled “Phase I correction of skeletal Class III malocclusion with a modified tandem appliance”, published on pages 150-153, Issue 4, Volume 8 in International Journal of Orthodontic Rehabilitation[1], the term “ANB -5” is incorrectly mentioned as “ANB 5” on page 150, under Case Report 3rdparagraph 3rdline.
The correct statement should be read as “Cephalometric analysis was indicative of a retrognathic maxilla (SNA 78), mildly prognathic mandible (SNB 83) causing a Class III skeletal base (ANB -5) with a horizontal growth pattern [Table 1]”

Abstract:
Cleft lip and palate (CLP) patients struggle from multiple limitations, both functionally and esthetically, impeding their social and psychological development. These patients adapt fairly to the functional requirements, but esthetic aspect is always compromised, which play a significant role in their overall development and their acceptance in the society. Early rehabilitation of the esthetic component in the form of replacement of the missing anterior teeth has a positive impact on the quality of life of these patients, which is usually neglected in the early phase of orthodontic treatment. This paper attempts to address the esthetic aspect of CLP patient with a clinical modification of conventional treatment modality.
