Abstract

Disclosed herein is a panoramic X-ray photographing apparatus and a method for pho¬ tographing using the same. The present invention relates to the panoramic X-ray photographing apparatus capable of conducting a panoramic photographing without generating X-ray in neck cervical vertebrae part employing a rotary arm driven in 3-axis direction. In case of scanning the neck cervical vertebrae part, a photographing can be conduct without X-ray. As a result, it is possible to prevent an image acquired by the neck cervical vertebrae part from being unclear. Also, an angle of incidence of X-ray at a photographing point can be controlled to be vertical, so that an image distortion phenomenon can be prevented. Furthermore, tempromandibular joint can be photographed at optimum enlargement ratio, thereby acquiring clear image.

Abstract

A dental unit chair is provided with a plurality of pipes, which supply clean water to respective parts of the unit chair. If the unit chair is not operated for a long time period, clean water in the pipes does not flow and remains therein for a long time period, so that a biofilm is formed on the inside wall of the pipes. This contaminates the inside of the pipes, and such contamination can secondarily infect a patient. Accordingly, the invention provides a clean water processing system for the dental unit chair, which can automatically drain or circulate clean water in the pipes of the unit chair, so that clean water does not remain in the water supply pipe for a long time period.

Abstract

A clean water drain system for a dental unit chair is disclosed. The clean water drain system of the present invention is characterized in that clean water, which remains in a water supply pipe (140) connected between a water purifier and a dental treatment assistant device of the unit chair, can be discharged outside by opening the water supply pipe. In detail, the present invention is constructed such that, when the dental unit chair is not in use, and thus clean water stagnates in the water supply pipe of the unit chair, the clean water can be discharged outside through a drain pipe (195) by controlling three-way valves (170) and (175) at a desired time and for a desired duration. Therefore, there is an advantage in that a biofilm is prevented from forming on the inner surface of the water supply pipe.

Abstract

Disclosed herein is a method for photographing using an X-ray photographing apparatus. The X-ray photographing apparatus includes a cephalometric photographing part and a panoramic and CT photographing part having a rotary arm supporting member, a rotary arm on which an X- ray source part and an X-ray sensor part having a panoramic sensor and/or a CT sensor are opposed to each other, and a rotary arm driving means. The method for photographing using the X-ray photographing apparatus includes the steps of: 1) locating a patient's head part (object) on a photographed position; 2) varying and regulating a distance between the X-ray source part and the X-ray sensor part of the rotary arm according to panoramic photographing or CT photographing; and 3) irradiating X-rays to the object to photograph the object. So, the present invention provides the optimum enlargement ratio according to whether the panoramic photographing or the CT photographing is conducted, and allows the user to simply conduct cephalometric photographing by separating the panoramic sensor and/or the CT sensor or moving the X-ray sensor part or the X-ray source part.
