Abstract:

Virtual Reality (VR) applications in medicine had significant improvements. 3D visualization of various anatomical parts using advanced medical scanner images, anatomy education, surgery operation simulation, virtual simulator for laparoscopic skills, virtual endoscopy, psychotherapy and rehabilitation techniques are some of the VR applications in medicine. Integration of the haptic devices into VR applications increased quality of the systems. By using haptic devices, the user can not only feed information to the computer but can receive information from the computer in the form of a felt sen

Abstract:

The use of composite materials for dental fillings has become more common due to demands for more esthetic filling materials and a national ban against using mercury-containing products, among others dental amalgam. However, one of the drawbacks with composites is their polymerization shrinkage. Filler particles are incorporated into composites among other things to minimize the shrinkage. The sizes of the filler particles have in recent years become smaller and most composites have nano-particles incorporated. The aims of the study were to investigate if a) the filler load, b) the curing time

Abstract:

Many dental devices combine acrylic (i.e. poly-methyl methacrylate or bisphenol A-glycidyl methacrylate) and metallic parts (i.e. titanium or stainless steel) that are bonded together. These devices often present catastrophic mechanical failures due to weak bonding between their acrylic and metallic components. These devices include dental prostheses, combining metallic frameworks (i.e. titanium) and wrought wires with acrylic resin; and orthodontic appliances, combining acrylic resin with stainless steel wrought wires or composite with stainless steel brackets.

A Denial of Service (DoS) attack is an incident in which the user is deprived of the services of a resource he is expected to have. With the increasing reliance on mobile devices like laptops and palmtops, a new type of DoS attack is possible that attacks the batteries of these devices, called "sleep deprivation attacks". The goal of sleep deprivation attacks is to rapidly drain the battery of the mobile devices, rendering the device inoperable long before the expected battery lifetime, thus denying the service the user expects from the mobile device.

Polyetheretherketone (PEEK) is a recent alternative as it is lighter and causes less wear of opposing retained teeth. Biofilm formation is a permanent daily struggle for patients as it can be found in nearly all surfaces exposed to the natural environment. Therefore, the interest in a new device capable of removing

Nowadays, the way to solve this kind of problem is developed into using the artificial tooth to replace the permanent tooth through dental implant operation. From the clinical experience of dental implant surgery, it is generally believed that the osseointegration (postoperative implant Stability) is the key to a successful surgery.
