Background: The sinus lift technique may be difficult to perform if an aberrant anatomy is encountered during surgical exposure, such as when a septum present on the floor. objective of this study was determine prevalence, size, location, and morphology maxillary septa in atrophic/edentulous non‐atrophic/dentate segments. Methods: sample population consisted 100 patients (41 women 59 men, with mean age 50 years, ranging between 19 87 years) for whom treatment being planned implant‐supported...
The aims of this study were to determine the reaction craniofacial bones on protraction force transferred maxillary body, and whether or not midpalatal suture had opened during skeletal Class III treatment. A computerized tomograph was obtained from a dry skull with normal occlusion construct three-dimensional finite-element model (3D.FEM) teeth simulate actual bone reactions. 500 g applied at first premolar region, directed 20 degrees inferior occlusal plane. displacement stress...
The purpose of this study was to elucidate the differences prevalence and diameter posterior superior alveolar artery (PSAA) distance its inferior border from crest on computed tomography (CT) images according age sex.CT maxilla in 200 patients were randomly selected who underwent CT imaging at Yonsei University Dental Hospital, analyzed. PSAA maxillary sinus premolar molar area measured.The average 52.0%, it is higher males (64%) than females (40%). 1.52 ± 0.47 mm (mean SD), larger males....
Seo D‐G, Gu Y, Yi Y‐A, Lee S‐J, Jeong J‐S, Chang S‐W, J‐K, Park W, Kim K‐D, Kum K‐Y. A biometric study of C‐shaped root canal systems in mandibular second molars using cone‐beam computed tomography. International Endodontic Journal , 45 807–814, 2012. Abstract Aim To investigate the configuration canals molars, wall thickness and orientation thinnest area at 1‐mm intervals from orifice to apex by tomographic (CBCT) images. Methodology Three‐dimensional CBCT images 92 Korean having were...
The aim was to analyze the prevalence rate of proximal contact loss (PCL) between implant-fixed prostheses (IFPs) and adjacent teeth investigate associated factors.One hundred fifty participants were recruited for this prospective study from January 2009 December 2014. Two thirty-four IFPs supported by 384 implants posterior region followed up until June 2016. tightness had been recorded using aluminum strips different thicknesses with a regular interval after delivery. Proximal considered...
The purpose of this study was to evaluate the relationship between masseter muscle thickness, facial morphology, and mandibular morphology in Korean adults using ultrasonography.Ultrasonography used measure thickness bilaterally 40 (20 males, 20 females) performed relaxed contracted states. Facial photos panoramic radiography were for morphological analyses evaluated correlations with thickness. We also age, body weight, stature, constitution thickness.In relaxing, 9.8±1.3 mm females...
Abstract This study evaluated the performance of generative adversarial network (GAN)-synthesized periapical images for classifying C-shaped root canals, which are challenging to diagnose because their complex morphology. GANs have emerged as a promising technique generating realistic images, offering potential solution data augmentation in scenarios with limited training datasets. Periapical were synthesized using StyleGAN2-ADA framework, and quality was based on average Frechet inception...
Due to the possible occurrence of periodontal disease at an early age, it is important have proper toothbrushing habits as possible. With this aim, feasibility and concept a smart toothbrush (ST) capable tracing motion orientation information was suggested. In study, we proposed advanced ST system brushing region classification algorithm. order trace in mouth, required absolute coordinate ST. By using tilt-compensated azimuth (heading) algorithm, found inclination toothbrush, while inner...
This study describes the use of personal computer (PC)-based three-dimensional computed tomographic (3D CT) images in evaluation supernumerary and ectopically impacted teeth. Three selected cases were presented as examples more complex which 3D CT imaging added information not readily available from periapical, occlusal, or panoramic radiographs. Patients scanned occlusal plane to periapical region Digital Image Communications Medicine data transferred a laptop using network line. volume...
Background: The inferior alveolar nerve block (IANB) is the most common anesthetic techniques in dentistry; however, its success rate low.The purpose of this study was to determine correlation between IANB failure and mandibular skeletal characteristics Methods: In total, 693 cases lower third molar extraction (n = 575 patients) were examined study.The ratio condylar coronoid distances from foramen (condyle-coronoid [CC ratio]) calculated, skeleton then classified as normal, retrognathic, or...
Abstract Background School children are in a developmental period which permanent teeth replace primary dentition. It is also with high incidence of gingivitis and caries, can be improved adequate tooth brushing. Advances information technology have led to the development smart health devices that assist We compared effectiveness computer-assisted toothbrushing using instruction (TBI) method called toothbrush mirror (STM) system conventional TBI (verbal instructions) for plaque control...
