Objective: To evaluate the influence of dentofacial attractiveness using the 'Psychosocial Impact of Dental Aesthetics Questionnaire' (PIDAQ), Satisfaction with Life Scale (SWLS) and Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) in patients with cleft lip/palate (CLP), and non-cleft orthodontic patients (Non-CLP) and their parents. Materials and methods: Eighty patients (aged 11-19 years) comprising 40 CLP and 40 non-CLP were administered the PIDAQ and SWLS questionnaires to be rated individually by the patients, along with IOTN-AC rated by the patients and their parents, respectively...

OBJECTIVES: The fitting of aligners on anchorage teeth is a crucial factor in clear aligner orthodontics. The purpose of this experimental study was to evaluate the fitting of two aligner systems, Invisalign and CA-Clear Aligner, using scanning electron microscopy (SEM). MATERIALS AND METHODS: Passive aligners (Invisalign and CA-Clear Aligner) were adapted on resin casts obtained by stereolithography (STL) files of a patient, and then sectioned buccolingually. Upper and lower central incisors, upper and lower first premolars, and upper and lower first molars were the regions analyzed...

OBJECTIVES: To determine upper incisor root resorption, volume loss, and the relationship between root volume loss and tooth movement after 1 year of orthodontic treatment in patients with marginal bone loss. MATERIALS AND METHODS: A total of 30 women (46.3 ± 5.4 years old) with moderate upper incisor bone loss who required intrusion during orthodontic treatment were recruited. Pre- and post-treatment cone beam computed tomography images were reconstructed. Upper incisors at pre- and post-treatment were superimposed; labio- and palato-apical, middle, and coronal third root volumes were assessed...

Early loss of permanent teeth, congenitally missing lateral incisors or second premolars, extremely displaced or impacted canines, all result in a reduced upper dentition. That leads to the development of crossbite in the maxillary dentition. Partial denture prosthesis, dental implants, and space closure by fixed orthodontics are the various means of treating the edentulous spaces. Protraction of molars is time taking and challenging. Temporary anchorage device (TAD) helps to protract molars without anchorage loss...

PURPOSE: The objective of this study was to evaluate the anterior tooth movement without and with bonded fixed orthodontic retainers under incremental loading conditions. MATERIALS AND METHODS: Six extracted mandibular anterior human teeth were embedded in acrylic resin in True Form I Arch type and 3D reconstruction of Digital Volume Tomography (DVT) images (0.4 mm3 voxels) were obtained. The anatomy of each tooth was segmented and digitally reconstructed using 3D visualization software for medical images (AMIRA, FEI SVG)...

Transposition of teeth - mutual exchange of the teeth position in the dental arch, it's a rare anomaly of the dentoalveolar apparatus. Most often in the transposition process the upper canines are involved in combination with the first premolars. Anomaly is mainly caused by an incorrect location of the teeth germs. Full correction is optimal in the treatment of transposition in terms of function and aesthetics, but in most cases, the movement of these teeth in their physiological position is impossible. Aim - to define and argue the tactics of the orthodontist in the treatment of patients with teeth transposition...

OBJECTIVE: To evaluate the effects of bracket removal using an erbium laser on the pulp temperature and enamel surface. BACKGROUND: Removal of orthodontic brackets with conventional debonding pliers may result in enamel cracks. To avoid damage to the enamel surface and effectively remove metal or ceramic brackets, different types of lasers, such as Nd:YAG, CO2 , TM:YAP, diode laser, or Er:YAG, have been introduced for debonding. MATERIALS AND METHODS: A total of 55 brackets (n = 55; 20 metal and 35 ceramic ones) were bonded to 55 caries-free premolars extracted for orthodontic indications...

This study examined the compatibility of 3D-printed artificial teeth and extracted teeth by combining oral cone-beam computed tomography (CBCT) and multi-jet printing technology to print the extracted teeth in vitro. The 3D-printed artificial teeth were then used to choose a master gutta-percha with an appropriate working length and taper to fill root canals. The quality of root canal-filling was evaluated via X-ray. Twenty orthodontically extracted premolars with a single root canal were collected and CBCT-scanned, and the scan data were extracted and converted to 3D models using MIMICS software, which in turn were used to 3D-print artificial teeth using multi-jet printing technology...

OBJECTIVE: The purposes of this study were to present a prototype of a bracket-positioning gauge, which makes vertical inclination of the instrument difficult, allowing a reduction of vertical bracket positioning error, and to test its accuracy in bracket positioning by groups of individuals with different clinical experience and in specific groups of teeth. METHODS: For the testing of the prototype, four groups of six participants each were used: Group 1 was composed of undergraduate students in the dental school, who had no previous experience in bonding orthodontic attachments; Group 2 was composed of orthodontic graduate students in the dental school; Group 3 consisted of orthodontists with a maximum of 5 years of clinical experience; Group 4 comprised orthodontists with more than 5 years of clinical experience...

OBJECTIVE: This study aimed to assess if additional vertical bitewing (VBW) and/or occlusal (OC) radiographs may change initial judgment based only on periapical radiograph (PAR) about the final position of orthodontic mini-implants (OMI). METHODS: Subjective and objective analyses were performed. Radiographic images of 26 OMI were divided into four groups: PAR, PAR+VBW, PAR+OC and ALL (PAR+VBW+OC). For subjective analysis, five observers were asked to assess if the position of OMI was favorable to its success, using questionnaires with a four-point scale for responses: 1= definitely not favorable, 2= probably not favorable, 3= probably favorable, or 4= definitely favorable...

The teeth become very close to each other when they are crowded, but their structures remain individualized and, in this situation, the role of the epithelial rests of Malassez is fundamental to release the EGF. The concept of tensegrity is fundamental to understand the responses of tissues submitted to forces in body movements, including teeth and their stability in this process. The factors of tooth position stability in the arch - or dental tensegrity - should be considered when one plans and perform an orthodontic treatment...

Patients undergoing radiotherapy treatment present more susceptibility to dental caries and the use of an orthodontic device increases this risk factor due to biofilm accumulation around the brackets. The objective of this study was to evaluate the shear bond strength to irradiated permanent teeth of orthodontic brackets bonded with conventional glass ionomer cement and resin-modified glass ionomer cement due to the fluoride release capacity of these materials. Ninety prepared human premolars were divided into 6 groups (n=15), according to the bonding material and use or not of radiation: CR: Transbond XT composite resin; RMGIC: Fuji Ortho LC conventional glass ionomer cement; GIC: Ketac Cem Easymix resin-modified glass ionomer cement...
