Definitions

• This invention relates generally to positioning devices for positioning, holding and stabilizing dental x-ray film or digital sensors during implant surgery. More particularly the invention relates to an improved dental positioning and stabilizing device that does not require a patient to bite down or manually hold it in position in order to take an x-ray.
• Dentists typically use intraoral radiographs ("x-rays") to obtain images of their patients '1 teeth to aid in diagnosis and treatment.
• x-rays intraoral radiographs
• an electronic sensor is placed in the patient's mouth behind the tooth to be examined.
• the electronic sensor or film is secured to a positioning device or is contained within a cartridge, typically cardboard or plastic.
• the sensor is placed behind the tooth while the holder extends through the bite area and the patient bites down on the holder to hold the sensor in place.
• the x-rays pass through the tooth and imprint on the sensor, which converts the x-rays into an electrical signal.
• the electrical signal is transmitted over a wire connected to a computer, either directly or though a module containing intermediate processing circuitry.
• the computer then processes the signal to produce an image on an associated output device, such as a monitor or a printer.
• an associated output device such as a monitor or a printer.
• x-ray film can be exposed and developed to offer the same or similar vie w of the desired area
• Intra-oral x-rays are also required in denial implant surgery.
• Denial implant surger is a procedure that replaces damaged or missing teeth with artificial teeth that look and function like real teeth.
• Dental implants are surgical iy placed in the jawbone, where they serve as the roots of missing teeth. To place the implant, the surgeon uses a dental drill including a driver and bit to drill through the patients' tissue and bone.
• the titanium implant includes a threaded outer poition that is screwed into the bone by the driver.
• An abutment portion is coupled to the titanium implant and extends out of the patient's gum and into the oral cavity. A cosmetic tooth is then attached to the abutment portion.
• Dental implants are often placed close to adjacent teeth and drilling into the roots of adjacent teeth while placing implants can cause irreparable harm. Consequently, it is critical for the implant to be placed as substantially parallel as possible to the roots of the adjacent teeth, it would be ideal for the dentist to take an x-ray prior to removing the drill and drill bit from the patient's jaw/bone so that she could ascertain correct and substantially parallel placement of the drilled hole,
• this task is complicated by several factors. First, the drill bit being x- rayed is high above the occlusal plane. Therefore, if a bite block sensor holder were used and a patient had to bite down in an attempt to stabilize the sensor/film holder, the drill bit would interfere with the biting action thus preventing stabilization.
• this invention provides a sensor positioning and stabilizing device which overcomes the above-mentioned problems. More specifically, the invention provides a sensor/film positioning and stabilizing device wherein the device is operably coupled to the drill bit or implant driver shank after the dentist drills through the patient's jaw bone.

• the invention includes a finger positioning tab that provides the surgeon with greater freedom in orienting the sensor.
• the invention is relatively thin, which also contributes to the improved ergonomics of the sensor positioning and stabilizing device, and enables the sensor to get closer to the target area, thereby improving the image data transmitted by the sensor to the computer.
