ABSTRACT Introduction New design of brackets have been introduced in the field of orthodontics in the recent past, and one of such advancement is the self-ligating brackets. These brackets are said to have less friction, with a shorter period of treatment. Better patient acceptance and good treatment results are some of the other advantages offered by self-ligating brackets. Hence, we comparatively evaluated root resorption of anterior teeth by self-ligating and conventional preadjusted brackets in cases of severe anterior crowding in class I patients. Materials and methods The present study was carried out at the department of orthodontics in a dental institution and included 140 patients that presented with the chief complaint of Angle class I malocclusion with crowding of more than 6 mm in the anterior tooth region. Two groups were formed with 70 patients in each group. In one group self-ligating brackets were used, while in other group conventional brackets were used. Malmgren's method was sued for evaluating the root resorption score ranging from 0 to 4. All the results were analyzed by the Statistical Package for the Social Sciences software. Chi-square test, nonpaired t-test, and paired t-test were used to evaluate the level of significance. Results The mean age of the patients in groups I and II was 13.92 and 13.81 years respectively. While comparing age of the patients and time duration of the treatment, no significant results were obtained. While comparing the root resorptions at various time intervals in groups I and II patients, significant results were obtained. While comparing the root resorptions in between groups I and II patients, no statistically significant results were obtained (p-value > 0.05). Conclusion Statistically similar amount of resorption is seen in patients in both the groups either on self-ligating brackets or on conventional preadjusted brackets during treatment of Angle class I patients with severe anterior crowding. Clinical significance In treating anterior crowding patients with Angle class I patients, choice of brackets has no effect on the amount of root resorption.

Abstract Introduction Objective of this study was to investigate the incidence and severity of apical root resorptions (ARR) during orthodontic treatment with aligners. Materials and methods The sample comprised 100 patients (17–75 years of age) with a class I occlusion and anterior crowding before treatment, treated exclusively with aligners (Invisalign®, Align Technologies, Santa Clara, CA, USA). The following teeth were assessed: upper and lower anterior teeth and first molars. Root and crown lengths of a total of 1600 teeth were measured twice in pre- and post-treatment panoramic radiographs. Afterwards, relative changes of the root length during treatment were calculated by a root-crown-ratio taking pre- and post-treatment root and crown lengths into consideration. A reduction of this ratio was considered as a shortening of the initial root length. Additionally, tooth movements of the front teeth were assessed by lateral cephalograms and the 3-dimensonal set up of each patient. Results All patients had a reduction of the pre-treatment root length with a minimum of two teeth. On average 7.36 teeth per patient were affected. 54% of 1600 measured teeth showed no measurable root reduction. A reduction of >0%-10% of the pre-treatment root length was found in 27.75%, a distinct reduction of >10%-20% in 11.94%. 6.31% of all teeth were affected with a considerable reduction of >20%. We found no statistically significant correlation between relative root length changes and the individual tooth, gender, age or sagittal and vertical orthodontic tooth movement; except for extrusion of upper front teeth, which was considered as not clinical relevant due to the small amount of mean 4% ARR. Conclusions The present study is the first analyzing ARR in patients with a fully implemented orthodontic treatment with aligners (i.e. resolving anterior crowding). The variety was high and no clinical relevant influence factor could be detected. A minimum of two teeth with a root length reduction was found in every patient. On average, 7.36 teeth per patient were affected.

In planning orthodontic cases that include extractions as an alternative to solve the problem of negative space discrepancy, the critical decision is to determine which teeth will be extracted. Several aspects must be considered, such as periodontal health, orthodontic mechanics, functional and esthetic alterations, and treatment stability. Despite controversies, extraction of teeth to solve dental crowding is a therapy that has been used for decades. Premolar extractions are the most common, but there are situations in which atypical extractions facilitate mechanics, preserve periodontal health and favor maintenance of the facial profile, which tends to unfavorably change due to facial changes with age. The extraction of a lower incisor, in selected cases, is an effective approach, and literature describes greater post-treatment stability when compared with premolar extractions. This article reports the clinical case of a patient with Angle Class I malocclusion and upper and lower anterior crowding, a balanced face and harmonious facial profile. The presence of gingival and bone recession limited large orthodontic movements. The molars and premolars were well occluded, and the discrepancy was mainly concentrated in the anterior region of the lower dental arch. The extraction of a lower incisor in the most ectopic position and with compromised periodontium, associated with interproximal stripping in the upper and lower arches, was the alternative of choice for this treatment, which restored function, providing improved periodontal health, maintained facial esthetics and allowed finishing with a stable and balanced occlusion. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO), as part of the requirements for obtaining the BBO Diplomate title.

ABSTRACT Objective: To compare the magnitude of external apical root resorption (EARR) of maxillary incisors in patients with mild to moderate anterior crowding, treated with lingual and conventional (labial) orthodontics. Materials and Methods: The sample comprised 40 patients divided into two groups: lingual (20 patients) and conventional buccal brackets (20 patients). Patient ages ranged from 11 to 45 years, and the study included 12 men and 28 women. Apical root resorption was measured from periapical radiographs obtained at the beginning of treatment (T1) and at the end of the leveling phase (T2). Periapical radiographs were scanned and transferred to the CorelDraw X7 image-processing program, in which measurements of root lengths were performed. For intragroup and intergroup comparisons between the T1 and T2 phases, paired and independent t-tests, respectively, were used at 5% significance. Results: There was significant apical root resorption for all teeth evaluated; the magnitude of the EARR (T2−T1) ranged from −0.35 mm to −0.63 mm in the lingual group, and from −0.66 mm to −0.85 mm in the conventional group. Although there was an intergroup variation in the magnitude of EARR observed, no statistically significant differences were found. Neither group presented any teeth with resorption ≥1 mm. Conclusions: The magnitude of apical root resorption in maxillary incisors in patients with anterior crowding was similar regardless of orthodontic technique, lingual or conventional. Both techniques resulting in an apical rounding considered clinically insignificant.

Abstract Objectives: To test the hypothesis that the sagittal position of the anterior teeth has no effect on pharyngeal airway dimension or hyoid bone position and to investigate the influence of orthodontic retraction of the anterior teeth on each section of pharynx and hyoid position. Materials and Methods: Forty-four Class I bimaxillary protrusion adults, treated with preadjusted appliances and maximum anchorage after extraction of four premolars, were divided into two groups according to their vertical craniofacial skeletal patterns. Pretreatment and posttreatment variables were compared using paired t-test, and the relationship between pharyngeal airway size and dentofacial variables was analyzed using Pearson correlation coefficient. The changes of pharyngeal airway size and hyoid position after treatment were compared between two groups using independent t-test. Results: Upon retraction of the incisors, the upper and lower lips were retracted by 2.60 mm and 3.87 mm, respectively. The tip of upper incisor was retracted by 6.84 mm and lower incisor retracted by 4.95 mm. There was significant decrease in SPP-SPPW, U-MPW, TB-TPPW, V-LPW, VAL, C3H, and SH (P < .05). No statistically significant different changes were observed in the dentofacial structures, pharyngeal airway, and hyoid position between the two groups after the treatment. There was a significant correlation between the retraction distance of lower incisor and the airway behind the soft palate, uvula, and tongue. Conclusions: The pharyngeal airway size became narrower after the treatment. Extraction of four premolars with retraction of incisors did affect velopharyngeal, glossopharyngeal, hypopharyngeal, and hyoid position in bimaxillary protrusive adult patients.

Clarity of pronouncations for early detection of oral disorders in children has been standardized into an Indonesian speech list that is popularly spoken by primary school children, but it requires a clinical application to be used as a speech test tool lists. The purpose of this study is that the standardized Indonesian speech list can be applied clinically in the case of Angle Class I malocclusion with protrusive anterior teeth in male children aged 9 and 12 years. The list is expected to be used as a test tool for speech disorders by looking at the spectrum patterns of speech sound frequency using Readability Meter tool. The arrangement of Indonesian speech list that is popular at children in school age is a contribution to the development of early detection of cavum oris abnormalities that occur in children to ease and accelerate the determination of diagnosis. This study was conducted using analytical epidemiological method with cross sectional design; the subjects were observed one time. The subjects were 24 male children from Javanese ethnic; 12 of there were 9 years old and the other 12 were 12 years old with protrusive anterior teeth and overjet 3-4 mm. Both of the groups pronounced the Indonesian speech list containing the dominant sound frequency in malocclusion Angle class I protrusive variation in the form of words /bakteri/, /demokrasi/, /formulir/, /konveksi/, /limbah/, /nasional/, /ringkas/, /samudera/, /takjub/, /ventilasi/. The recording was directly conducted in a soundproof room through sound recorder program using flat microphones and sound processing mixer. Then, the dominant sound frequency (Hz) and the display of the spectrum patterns of the sound frequency was measured using Cool Edit Pro 2.0 and Excel software. An Excel analysis shows highly significant differences between male children aged 9 years and 12 years in Angle Class I malocclusion with protrusive variations in speech of 10 Indonesian words with the coefficient of determination “R” in the equation chart of spectrum patterns of sound frequency. Male children aged 9 years have a spectrum pattern of sound frequency which is lower and flatter than those aged 12 years.

Bruxism is a parafunctional habit of grinding and clenching the teeth. It is common for patients with fixed orthodontic treatment to experience bruxism. When dealing with these patients, clinicians could initiate the bruxism treatment in conjunction with the orthodontic treatment. This case report will analyze the effects of Trainer for Braces (T4B) in a patient with malocclusion and bruxism habit. A 21 year old female patient complained of her crowding in upper and lower anterior teeth. The objective examination shows protrusion and crowding in upper and lower teeth, deep overbite, severe maxillary and mandibulary constriction, 47 linguoversion and bruxism habit. Angle Class I with skeletal Class I malocclusion, bidental protrusion, overjet 3.7 mm, overbite 4 mm, crowding, edge to edge bite, crossbite and bruxism habit. The orthodontic treatment used fixed preadjusted Edgewise appliance with Lingual Arch Bar for expansion and lingoversion molar correction. Trainer for Braces (T4B) was also prescribed to treat her bruxism. After 8 months of treatment, the crowding in upper and lower teeth was corrected, dental arch expansion was achieved, linguoversion molar was corrected, and overjet and overbite became 3.5 mm and the treatment was still on going. The combination of fixed preadjusted Edgewise appliance with Trainer for Braces (T4B) can be considered as an effective therapy for correcting malocclusion in bruxism patient.

Angle Class I malocclusion with bimaxillary protrusion is characterized by severe buccal tipping of incisors, which causes upper and lower lip protrusion. First premolars extraction is recommended to reduce facial convexity as a result of anterior teeth retraction, which keeps canines and first molars in key to occlusion. In order to yield orthodontic results that are compatible with ideal esthetic and cephalometric outcomes, the space closure phase needs to be carried out with overbite and incisors torque control. The majority of cases also requires maximum anchorage of posterior teeth. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO) as a requirement for the title of certified by the BBO.
