Disclosed is a sensor holder for an intraoral X-ray sensor including a front surface receiving incident x-rays, a rear surface, and a fastener, including a coupler including a grip fitted over a side surface of the fastener to enclose the same, and a support connected to the grip and facing in a forward direction of the intraoral X-ray sensor while covering the rear surface and a side surface of the intraoral X-ray sensor, a connector connected to the support and extending in the forward direction of the intraoral X-ray sensor, and a handle connected to the connector, wherein the coupler is made of a synthetic resin material with a first hardness (L1), and at least one of the connector and the handle is made of a synthetic resin material with a second hardness (L2) greater than the first hardness.

A dental imaging system may include an X-ray source, a first optical alignment device, and a dental image collection device. The dental image collection device may include a mouthpiece, at least one electronic X-ray sensor carried by the mouthpiece, and a second optical alignment device carried by the mouthpiece and cooperating with the first optical alignment device to facilitate optically aligning the mouthpiece with the X-ray source. The system may also include a dental image processing device coupled to the at least one electronic X-ray sensor.

Methods and systems are described for operating an intra-oral imaging sensor that includes a housing, an image sensing component at least partially housed within the housing, and a magnetometer at least partially housed within the housing. An output of the magnetometer indicative of an actual magnetic field that impinges the intra-oral imaging sensor is compared to data indicative of a first expected magnetic field. In response to determining, based on the comparison, that the actual magnetic field matches the first expected magnetic field, the electronic processor alters the operation of the imaging system. In some embodiments, the electronic processor causes the intra-oral imaging sensor to operate in a low-power state in response to determining that the actual magnetic field matches a first expected magnetic field indicative of placement of the intra-oral imaging sensor in an imaging sensor storage compartment.

A sensor holder for retaining a dental radiation sensing device includes an elongated support member, at least one pair of retention guides attached to the support member, and at least one bite block attached to the support member. The retention guides are capable of holding an associated dental radiation sensing device. The bite block has a leading edge which is first inserted into a mouth of a patient and a trailing edge. The leading edge defining a recess into which structure within the mouth of the patient can seat. At least one of the retention guides may be moveable relative to the other retention guide.

A dental x-ray sensor holder 1 and sheath 4 for affixing a sensor to a backing plate 2 of the holder 1. The dental x-ray sensor holder 1 and sheath 4 generally includes a sensor holder 1 with a backing plate 2, having one or more spring arms 3, and affixed to or formed contiguously with a proximal end of a bite block 9 of the holder 1. It also includes a sensor sheath adapted to secure a sensor to the backing plate for X-ray acquisition.

A dental x-ray sensor holder 10 for securing an x-ray sensor 1 to a holder using suction created between the sensor and a backing plate 3 of the sensor holder. The dental x-ray sensor holder generally includes a bite block 2 with a first end and a second end, a backing plate 3 affixed to or formed contiguously with the second end of the bite block, and an opening 17 to a cavity 20 in the holder, wherein said cavity 20 leads an evacuation chamber 14 for creating a vacuum between the holder and an X-ray sensor.

Systems, devices, and methods are described for providing, among other things, an intra-oral x-ray imaging system configured to reduce patient exposure to x-rays, reduce amount of scatter, transmission, or re-radiation during imaging, or improve x-ray image quality. In an embodiment, an intra-oral x-ray imaging system includes an intra-oral x-ray sensor configured to communicate intra-oral x-ray sensor position information or intra-oral x-ray sensor orientation information to a remote x-ray source.

A positioning and retaining system for intra-oral sensors includes a holder shaped to hold a curved intra-oral sensor, and a curved or flexible intra-oral sensor configured to be coupled to the holder.

A protective means has a pouch-like structure, comprising an orifice for inserting X-ray imaging media in the protective means. In connection with the protective means there is also a closing means, which is arranged to close the orifice. Also in connection with the protective means there is a fastening means for fastening a closing means to the pouch-like structure of the protective means so that upon fastening the closing means the fastening means is arranged to be located on both sides of the orifice.

A dental sensor holder including a loop of material and an adjustable bond. The adjustable bond portion is located on the inside of the loop which may selectively be engaged to join adjacent portions of the loop into a functional bitewing.
