To compare the accuracy of complete-arch scans and quadrant obtained using a direct chairside intraoral scanner.Intraoral were from 20 adults without missing teeth except for third molar. Maxillary mandibular carried out, 4 each arch performed to obtain right posterior, anterior, left posterior scans. Complete-arch compared with corresponding model best-fit surface-based registration. Shell/shell deviations computed between In addition, shell/shell calculated also individual tooth in...
This in vivo study evaluated the difference of two well-known intraoral scanners used dentistry, namely iTero (Align Technology) and TRIOS (3Shape). Thirty-two participants underwent scans with scanners, as well conventional alginate impressions. The obtained were compared each other also corresponding model by means three-dimensional surface analysis. average differences between on surfaces color-mapping. direction its scan calculated at all points surfaces. 0.057 mm maxilla 0.069 mandible....
Abstract Objective The rapid development of artificial intelligence technologies for medical imaging has recently enabled automatic identification anatomical landmarks on radiographs. purpose this study was to compare the results an cephalometric analysis using convolutional neural network with those obtained by a conventional approach. Material and methods Cephalometric measurements lateral cephalograms from 35 patients were program program. Fifteen skeletal measurements, nine dental two...
This study aimed to evaluate the accuracy of deep learning-based integrated tooth models (ITMs) by merging intraoral scans and cone-beam computed tomography (CBCT) for three-dimensional (3D) evaluation root position during orthodontic treatment compare fabrication process with manual method.Intraoral corresponding CBCT before after were obtained from 15 patients who completed premolar extraction. A total 600 ITMs generated using learning technology methods at pretreatment. Posttreatment into...
To examine and compare the maxillofacial characteristics affecting chin deviation three-dimensionally in facial asymmetry patients with mandibular retrusion prognathism.Maxillofacial computed tomography (CT) scan data were obtained from 48 orthognathic surgery (24 cases of 24 prognathism) asymmetry. Although was assessed on basis ANS-to-menton line frontal cephalograms, its contributing factors evaluated three-dimensional CT images. Maxillary height, ramus length, ramal inclination, lateral...
To propose the utilization of virtual tooth models (VTMs) created by combining root data from cone-beam computed tomography (CBCT) and crown gathered through intraoral scanning to assess inter-root distance angulation during orthodontic treatment when repeated radiographic monitoring becomes necessary. Patients with planned dental implant placement in edentulous areas or after who underwent CBCT scans at pretreatment posttreatment stages were selected. Tooth fabricated merging intraorally...
ABSTRACT Objective: To evaluate changes in shape and alterations thickness vertical marginal bone levels of the alveolar around maxillary mandibular incisors before after orthodontic treatment with premolar extraction using geometric morphometric analysis. Materials Methods: Thirty-six patients Class I bialveolar protrusion who underwent were included. Cone-beam computed tomographic scans obtained from treatment. Five fixed landmarks 70 semilandmarks used to represent morphology incisors....
The purpose of this paper was to introduce a method for creating digital virtual patient by combining cone-beam computed tomography (CBCT), intraoral scan, and facial scan with high accuracy integration. CBCT were obtained from initial visit. created using the integration these imaging modalities. Once generated, workflow could be applied consultation, diagnosis, treatment planning, tooth setup, simulation, post-treatment evaluation. technology allows clinicians improve diagnosis outcome. in...
ABSTRACT Objectives The need for intraoral scanning in the presence of brackets has increased monitoring tooth movement during orthodontic treatment. purpose this study was to evaluate effect bonded surfaces on scans. Materials and Methods Intraoral scans were performed 30 patients using both iTero Trios scanners before after bonding brackets. two sets each patient with without superimposed a best-fit algorithm, three-dimensional (3D) surface analysis performed. In superimposition,...
To evaluate maxillary and mandibular alveolar basal bone widths using cone-beam computed tomography (CBCT) to verify the correlation between CBCT images posteroanterior (PA) cephalograms.
The purpose of this study was to evaluate the effectiveness use Reference Ear Plug (REP) during cone-beam computed tomography (CBCT) scan for generation lateral cephalograms from CBCT data.Two scans were obtained 33 adults. One acquired using conventional methods, and other with REP. Virtual created each image traced compared tracings real same subject.CBCT REP resulted in a smaller discrepancy between virtual cephalograms. In comparing cephalograms, no measurements significantly differed...
To investigate dentists' perceptions and attitudes regarding radiation safety in dental practices Korea.207 dentists participated this study. An anonymous survey was conducted the following areas: years of practice, characteristics radiography equipment, knowledge diagnostic reference levels, prescription radiographs, use protection procedures participation program. Data were evaluated according to frequency distribution; χ test; Fisher's exact test, which used statistical significances (p <...
This case report introduces a treatment in mandibular prognathism correction by combining the surgery-first (SF) approach and clear aligners. An intraoral scanner (TRIOS 3, 3Shape, Copenhagen, Denmark) virtual setup program (OrthoAnalyzer, 3Shape) were used for simulation. All aligners fabricated using 3-dimensional printer. The total was completed within 3 months after surgery. immediate improvement of facial profile obtained SF approach, rapid esthetic tooth movement achieved demonstrated...
Purpose The purpose of this study was to investigate the influence head motion on accuracy three-dimensional (3D) reconstruction with cone-beam computed tomography (CBCT) scan. Materials and Methods Fifteen dry skulls were incorporated into a controller which simulated four types during CBCT scan: 2 horizontal rotations (to right/to left) vertical (upward/downward). Each movement triggered occur at start scan for 1 second by remote control. Four maxillofacial surface models one control model...
Previous studies have suggested that functional dominance in one part of the body can be correlated with another part. Thus, present research aimed to determine whether brain laterality (handedness, footedness, earedness, and eyedness) was related mixing ability chewing side preference.Fifty-four volunteers who were not undergoing any form dental treatment took this study. Self-defined determined through a questionnaire. The performed five tasks laterality, which identified by used perform...
