We are proud to offer this state of the art radiographic imaging system here at Denora Worcester & were one of the first in the country to install and offer the service to our patients & other dentists. Our CBCT equipment is a dedicated CBCT machine that produces a very sharp 3D scan of your jaw with the minimum possible radiation exposure. We train regularly and audit our processes so that we are able to keep abreast of all the regulations that we comply with.
WHAT IS DENTAL CONE BEAM CT?
A CBCT scan, also known as Cone Beam Computerized Tomography, is an x-ray technique that produces 3D images of your skull that allows visualization of internal bony structures in cross section rather than as overlapping images typically produced by conventional x-ray exams & is used to produce images that are similar to those produced by conventional CT imaging with a significant reduction in the radiation dosage. Dental cone beam CT was developed as a means of producing high quality of images like a conventional CT but with a much smaller effective radiation exposure.
An x-ray beam, in the shape of a cone, is moved around the patient to produce a large number of images detected on a flat panel detector. The technology uses a special type of x-ray machine to provide a more detailed visualisation of the jaws & used commonly in situations where regular dental or facial x-rays are not sufficient like dental implant planning, TM Joint problems, wisdom teeth location, orthodontic planning, etc. This type of scan uses a digital radiography technology (filmless) to compute & generate a three dimensional (3-D) images of dental structures, sinuses, nerve paths and bone in the craniofacial region in a single scan. Images obtained with cone beam CT allow for more precise treatment planning.
Metal objects, including jewellery, eyeglasses, dentures and hairpins, may affect the CT images and should be left at home or removed prior to your exam. You may also be asked to remove hearing aids and dentures. You may be asked to remove any piercings, if possible. You should inform the operator if you have a pacemaker. Pacemakers do not hinder the use of CT
HOW DOES THE PROCEDURE WORK?
During a cone beam CT examination, the C-arm or gantry rotates around the head in a complete 360-degree rotation while capturing multiple images from different angles that are reconstructed to create a single 3-D image. The x-ray source and detector are mounted on opposite sides of the revolving C-arm or gantry and rotate in unison. In a single rotation, the detector can generate anywhere between 150 to 200 high resolution two-dimensional (2-D) images, which are then digitally combined to form a 3-D image that can provide your dentist or oral surgeon with valuable information about your oral and craniofacial health.
HOW IS THE PROCEDURE PERFORMED?
You will be asked to stand still in a particular position (just like a large dental x-ray), and any ‘stents’ or reference device will be placed in your mouth which your dentist may have provided. Your dentist or oral surgeon will position you so that the area of interest is centred in the beam. You will be asked to remain very still while the x-ray source and detector revolve around you for a 360-degree rotation or less. This typically can take between 14-16 seconds for a jaw volume capture either upper or lower jaw
WHAT WILL I EXPERIENCE DURING AND AFTER THE PROCEDURE?
You will not experience any pain during a cone beam CT exam, and you will be able to return to your normal activities once the exam is complete.
WHO INTERPRETS THE RESULTS AND HOW DO I GET THEM?
Your referring dentist, oral surgeon or radiologist (referrer) will receive the scan electronically & analyze the images. They may discuss the results with you directly or communicate the results to your referring physician or dentist. We are only the ‘operators’ and will make the scan as requested by the referrer using the principles of keeping the dose as low as possible and making sure that we are able to produce the most diagnostically acceptable scan to help your referrer to plan you treatment.
The focused x-ray beam reduces scatter radiation.
A single scan produces a wide variety of views and angles that can be manipulated allowing the clinician to compare asymmetries and assess a number of factors like the anatomy , angulations and pathologies in your jaw.
Cone beam CT scans provide more information that conventional dental x-ray, allowing for more precise treatment planning.
CBCT scanning is painless, non-invasive and accurate.
A major advantage of CT is its ability to image bone and soft tissue at the same time.
No radiation remains in a patient’s body after a CT examination.
X-rays used in standard CT scans or CBCT scans have no immediate side effects.
The ionising radiation effects will disappear from the body over a period of time as normal cell repair/ body’s immunity clears the risk over time.
There is always a risk of excessive exposure to radiation as a machine malfunction. However, the benefit of an accurate diagnosis will generally outweigh the risk. The machines and operators have to undergo regular rigorous monitored training & audits and inspections of equipments by HPA to make sure that this risk is minimised to adhere to the principles of keeping the exposure to ‘as low as reasonably possible’.
Please note that the smallest scan that our CBCT unit makes is for the either the entire maxilla or the entire mandible and we make sure that only the ticked jaw (upper or lower is scanned)
CT scanning is, in general, not recommended for pregnant women unless medically necessary because of potential risk to the baby.
Children are more sensitive to radiation, they should have a CT exam only if it is essential for making a diagnosis and should not have repeated CT exams unless absolutely necessary.
CT BOOKING FORM
Over the last three years, I have been with Denora in Worcester under the supervision of Dr Amit Pandey, & it has completely changed my view of Dentists. As a result of the work I have had done under the supervision of Dr Pandey, the health of my teeth & gums has improved dramatically and also the appearance of my teeth (and smile) has been transformed.
Everyone needs a dentist as a part of a healthy lifestyle. When you visit Denora you become a family member not just a patient. The care & consideration given to me through intensive treatment has been fantastic! It is no longer daunting attending the surgery.
My dentist referred me to Dr Amit Pandey at Denora for dental work that required specialist expertise. Amit talked me through an agreed and costed programme, gave me ongoing support and shown real kindness throughout its delivery. I have received such a professional and friendly service by all the staff at Denora that I am now registered with the practice – and, of course, I smile more confidently!!!
