Anatomically conforming intraoral dental radiographic sensor
A system is described for obtaining intraoral radiographic images using an anatomically conforming sensor and a method is described for correcting the projective distortions caused by the inclination of the plane of the imaging sensor relative to the x-ray beam. The purpose of the described sensor system is to reduce patient discomfort as compared to conventional planar intra-oral x-ray sensors, which tend to impinge on sensitive tissues within the oral cavity. An additional purpose of the described system is to allow for better coverage of the subject by allowing the sensor to fit closer against the surrounding tissues.
Universal intraoral digital sensor holder for existing digital sensor systems in dentistry
A universal dental digital sensor holder has a bite block connected to a rod that has a connector which is used to flexibly attach a sensor holder so as to allow rotational movement of the sensor relative to the bite block and multiple sensor holders are removably connected to the connector so that they can be used to obtain different radiographic projection views due to their differing configurations for holding the intraoral sensor in the patient’s mouth. The bite block can have an opening formed in it fitted with a sleeve to allow access to a tooth located beneath the opening in the patient’s mouth. A cable protector can be formed in the rod adjacent an anterior bite surface so that an intraoral sensor cable can be held adjacent the rod and at least partially protected from one or more teeth biting the anterior bite surface.
Intraoral radiological imaging sensor
The present invention relates to an intraoral radiological imaging sensor that eliminates dead space on its proximal side by moving the imaging integrator circuit control electronics to its distal side and/or location of the control electronics. imaging integrated circuit within an active pixel array, whether made by sacrificing active imaging area within a pixel or by deposition of the imaging integrated circuit control electronics on a separate layer below the imaging area.
Intraoral Radiographic Sensors with Cables Having Increased User Comfort and Methods of Using the Same
A radiological image sensor has an electronic substrate and an imaging chip held within a housing, the imaging chip having electronics that create a dead space, with a cable attached to the housing at a cable button connector, the dead space being at a short distal side of the generally rectangular sensor opposite the short mesial side at which the cable exits the cable button connector. The mesial side of the sensor either does not have a dead space created by electronics of the imaging chip or the dead space found on the mesial side of the sensor is less than approximately 4 mm, and, preferably, approximately 2 mm or less. The cable can be a flat cable with a length of approximately one meter or less that can be connected to a round cable.
Apparatus and method for retrofitting an intraoral radiology positioning device with a rectangular collimation device
A variable aperture X-ray collimating device that fits over existing intraoral radiographic sensor positioners enables clinicians to provide radiation protection for their patients while allowing the flexibility to accommodate various commercially available positioning kits. In addition, the variable aperture allows for easy accommodation of various sensor sizes.
Intraoral radiographic imaging sensors with minimized mesial imaging dead space
Disclosed is an intraoral radiological imaging sensor. The sensor comprises an electronics substrate and an imaging chip held within a housing. The imaging chip has electronics that create a dead space (9). The sensor also comprises a cable (6) attached to the housing at a cable button connector (11). The sensor has a generally rectangular shape with a mesial side towards which the cable (6) exits the cable button connector (11) and a distal side opposite which the cable (6) exits the cable button connector (11). The electronics are disposed within the housing such that the majority of the dead space (9) is created in the distal side of the sensor. (11).
