2D OPG and 3D CBCT at Smile Centre India

Dental imaging (Dental radiography) is an integral part of dental treatment. SmileCentre India has its own in-house state of the art dental imaging facility (2D OPG and 3D CBCT imaging) from Planmeca, Finland. The images are produced within seconds and digitally stored in the patient's file.

Orthopantomography (OPG)

OPG is an important and most common imaging method to assess the vertical bone volume and detect dental caries and periodontal diseases. It is a panoramic X-ray of the upper and lower jaws, including the teeth. OPG has many advantages including panoramic, easy and cheap to conduct, and informative regarding jaw morphology, bone density, etc. The OPG unit is specifically designed to rotate around the patient’s head during the scan and OPG will take approximately 20 seconds for imaging.

Dental Cone Beam CT (3D CBCT)

Dental cone beam computed tomography (CT) is a special type of x-ray equipment used to produce three-dimensional (3D) images of teeth, soft tissues, nerve pathways, and bone in a single scan. With cone beam CT, an x-ray beam in the shape of a cone is moved around the patient to produce a large number of images, also called views. Images obtained with cone beam CT allow for more precise treatment planning. CBCT is used only in situations where regular dental or facial x-rays are not sufficient because the radiation exposure from this scanner is significantly more than regular dental x-rays (OPG). However, cone beam CT has the advantage of lower radiation exposure compared to conventional CT.

Patient Guidelines

General Guidelines Prior to Imaging

An Orthopantomography (OPG) or cone-beam CT (3D CBCT) examination requires no special preparation. This procedure is not painful, but you will need to remain still for the duration of the scan.This typically can take between 20 to 40 seconds for a complete volume, also called a full mouth x-ray, in which the entire mouth and dental structures are imaged, and less than 10 seconds for a regional scan that focuses on a specific area of the maxilla or mandible.

Prior to the examination, the patient may be asked to remove anything that may interfere with the imaging, including metal objects, such as jewelry, eyeglasses, hairpins, and hearing aids. Although removable dental work may need to be removed. Women should always inform their dentist or oral surgeon if there is any possibility that they are pregnant.
