Publication number: 20180055615Abstract: The present disclosure relates to a damping dental post key configured to implant a dental root post for restoration of a tooth. The dental post key includes a body for handling and a post carrier having a key shape with respect to a head portion of the dental root post. During implantation of the dental post, rotation of the body compresses a set of springs in contact with the post carrier reducing a reaction force to a tooth root. In this way a limited force will be applied and a root fracture can be prevented. Further, the dental post key can be configured to have a fixed movement in a counterclockwise direction to remove the dental post and a free quarter-cycle movement with effort in a clockwise direction.Type: ApplicationFiled: September 1, 2016Publication date: March 1, 2018Applicants: National Guard Health Affairs, King Saud bin Abdulaziz University for Health Sciences, King Abdullah International Medical Research CenterInventor: Bassam Nawaf SRAYEDDIN

Patent number: 9267848Abstract: The thermometer using differential temperature measurements utilizes a pair of adjacent temperature sensors in order to measure the temperature of a common surface over a pre-selected period of time. The thermometer includes a housing and first and second thermistors mounted adjacent one another on the housing. The first and second thermistors are positioned against the surface, which can be a body part (for oral, rectal or axial body temperature measurements) or can be any other desired surface for which a spot check temperature reading is desired. A programmable current source pre-heats the second thermistor to a pre-selected temperature, while the first thermistor is initially at room temperature. A controller inside the housing causes both the first and second thermistors to take instantaneous temperature measurements of the surface at two successive times. The controller linearizes the measurements to predict the temperature of the surface, which is then displayed to the user.Type: GrantFiled: January 2, 2014Date of Patent: February 23, 2016Assignees: KING ABDULLAH INTERNATIONAL MEDICAL RESEARCH CENTER, KING SAUD BIN ABDULAZIZ UNIVERSITY FOR HEALTH SCIENCES, NATIONAL GUARD HEALTH AFFAIRSInventor: Abdulrahman Musa Al-Faifi
