The use of haptic devices in the medical field has become widespread in the last decade. In this study, a visio-haptic dental training system is developed using haptic and stereoscopic devices. Several advantages are offered by such a simulation system, including effective learning without any fear of making mistakes on a patient, possibility of repeating various dental operations, ease of evaluating student performance, and low-cost dental training even without an instructor. In this study, the biomechanical properties of enamel, dentin, pulp, and caries were modeled, and the parameters were fine-tuned to provide more realistic haptic sensations. Maxillary and mandibular dental arches and various dental instruments such as mouth mirror, probe, and dental drills were modeled in a 3D virtual environment. Probing and cavity preparation on teeth were implemented in the training system. Various graphical rendering methods (Surface Rendering in CPU, Iso-Surface Rendering, and Ray-Casting in GPU) were implemented and compared in performance. The implementation details and the software structure used are described. Finally, detailed performance tests by a group of dentists are conducted, and the results of these tests are presented. The performance tests found that dentists have a strong motivation to use the system and that in the aspects of usability, clarity, effectiveness, help/support provided, and satisfaction, the users' responses were above average.

Optimum Design of 6R Passive Haptic Robotic Arm for Implant Surgery Yılmaz, Serkan; Konukseven, Erhan İlhan (2010-07-10) The aim of this research was to design an optimum 6R passive haptic robotic arm (PHRA) to work in a limited workspace during dental implant surgery. Misplacement of an implant during dental surgery causes longer recuperation periods and functional disorders. In this study, a passive guidance robot arm was designed as a surgical aid tool for a dentist during the operation to reduce the surgical complications. Optimum design of a 6R robot is a complex issue since minimum energy has to be consumed while maximu...
Visual attributes of products as the factors influencing Users' emotional reactions: a study on dental instruments Çınar Okuşluğ, Kıvılcım; Ünlü, Canan Emine; Department of Industrial Design (2014) Despite the technological advances in the field of dentistry, it is asserted that the instruments that are used in treatments may be one of the reasons of negative emotions that are still effective on dental patients. However, studies that investigate how dental instruments trigger emotions of patients are so scarce. In this study that aims to overcome this deficiency, it is tried to show relationship between product appearance and individual’s emotional response on dental instruments. This thesis dwells on...
DENTAL PANORAMIC AND BITEWING X-RAY IMAGE SEGMENTATION USING U-NET AND TRANSFORMER NETWORKS KAYA, METE CAN; Akar, Gözde; Department of Electrical and Electronics Engineering (2023-1-23) With the advancement in medical imaging systems, and the underlying software platforms, diagnostics success in medicine improved significantly. Even though automatized systems are essential tools for diagnostic success, medical professional opinion is still used a lot, especially in dentistry. In the area of dentistry, x-ray images are wildly used for diagnostic purposes, i.e. to find caries, the location of embedded wisdom teeth, the health of the bone structure, etc. The dentist uses contrast and region-b...
Exploring behavior change features for mobile workout applications ÜNAL, Perin; Cavdar, Seyma Kucukozer; Taşkaya Temizel, Tuğba; Eren, Pekin Erhan; IYENGAR, Sriram (2017-08-23) With the rapid emergence of mobile technologies in recent years, mobile health (m-health) has become fundamental to healthcare. Persuasion strategies and behavior change support features are widely used in m-health applications to increase the effectiveness of these applications on users. However, in the literature, there is a lack of research to analyze the current situation of m-health applications particularly from the perspective of behavior change approaches. In this study, the workout applications in ...
Integrated circuit design for flip-chip bonded capacitive micromachined ultrasonic transducers Maadi, Muhammad; Bayram, Barış; Department of Electrical and Electronics Engineering (2013) In previous decades, the applications of ultrasound technologies in medical imaging and therapeutic systems have significantly increased. In conventional ultrasound systems, the transducer array is separated from the electronic instrumentation with multicore physical cabling. However, connection cables make the system too bulky and degrade the receive sensitivity in ultrasound 3D imaging applications because of the capacitance of long cables. The interface electronics for phased array ultrasound systems (im...
