Abstract: A bite-block and film-holding device is used with an x-ray film or a digital image sensor and held by a patient between teeth to align with an external camera device for dental radiographic imaging of the patient's teeth. The bite-block and film-holding device includes a disposable film holder having a bite block portion, a film-holding portion made of a plastic material, and a bonding member having a release layer attached thereto; and an aiming assembly having a coupling arm coupled to the disposable film-holder and an aiming ring assembly installed on the camera device and connected to the coupling arm. The aiming ring assembly is adjustable in position for the camera device to face at a right angle to the film-holding portion. After the dental radiographic imaging, the disposable film holder is separated from the aiming assembly and discarded to ensure the patient's oral cavity hygiene and health.

Abstract: An implant positioning device is fitted on to an orthodontic brace of a patient and used in between an X-ray projecting machine and an X-ray film. The implant positioning device includes a measuring standard member, that forms a detection region by means of a radiopaque material and has a positioning unit on one side of the detection region. The detection region is provided with at least one set of measuring scales. An encircled member is integrated with one side of the measuring standard member and forms an encircling main body that is connected to the orthodontic brace. A sleeved space is collectively formed by the encircling main body and the measuring standard member.

Abstract: The present invention provides a sheath for a disposable dental direct imaging digital device. The sheath for a disposable dental direct imaging digital device includes a bag structure that is made up of an elastic material, and is also made up of a positioning device that is placed in an opening of the bag structure. A direct imaging digital device may be inserted into the sheath. A first housing segment that is in connection with the opening exists on one end of the bag structure. The other end of the first housing segment is in connection with a second housing segment. A tapered channel is formed from the opening of the first housing segment towards the second housing segment. A positioning device may close or shrink the opening, so as to prevent the direct imaging digital device from sliding out of the sheath. The direct imaging digital device may be inserted into the first housing segment, and then may be inserted into the second housing segment.

Abstract: A hand-held direct digital image sensor device includes a connection handle having a grip portion, a bite portion, and a carrier portion provided with at least one male coupling unit; a soft protective cover provided with at least one female coupling unit for engaging with the male coupling unit; and a direct digital image sensor received in a receiving cavity defined in the protective cover. Through engagement of the male and female coupling units with one another, the soft protective cover and accordingly the direct digital image sensor received therein can be connected to an end of the connection handle and be extended into a patient's oral cavity without bringing too much discomfort to the patient. The used protective cover is discarded or disinfected to meet sanitary requirements in medical treatment.

Abstract: The present invention provides an implant positioning device for an orthodontic brace, that is fitted on to the orthodontic brace of a patient. The implant position device mainly includes a measuring standard member and at least one encircled member, whereby the at least one encircled member is used in conjunction with the orthodontic brace that is directly in connection with the measuring standard member. The measuring standard member forms a detection region having measuring scale by means of a radiopaque material. A positioning unit is configured on one side of the detection region. Moreover, the at least one encircled member forms an encircling main body that can be elastically extended. The encircling main body forms a sleeved space that can accommodate the orthodontic brace, and the size of the sleeved space can be adjusted.

Abstract: A multi-coordinate orthodontic implant positioning device includes a measuring reference member having a predetermined thickness and being provided thereon with measuring scales formed of a radiopaque material. The measuring reference member is connected at an edge to a fixing member for fixedly attaching to the patient's teeth. The measuring scales define a coordinate-type positioning structure, which includes at least a main coordinate system and a sub-coordinate system. The main coordinate system divides the positioning structure into a plurality of coordinate blocks, each of which has a main coordinate code readable from the main coordinate system; and the sub-coordinate system is provided in some specified ones of the coordinate blocks. Since the main coordinate system and the sub-coordinate system are two different and independent coordinate systems, the use of them enables primary and more accurate positioning of an implant point to effectively upgrade the efficiency in the orthodontic implant surgery.
