Cone Beam 3D Scan X-ray – Basics For Dental Implants

3D x-rays are used often for dental implant treatment. They help me increase the safety and precision of your dental implant surgery.  3D x-rays are often called CT scans, 3D scans, or cone beam scans. This can be done at an x-ray lab or at my office in Burbank.

Cone beam 3D scans are extremely safe and have very little radiation. In my office, I have a very technologically advanced machine that can take a limited view scan. This is called a “limited field of view.” The big advantage to you is that the radiation can be focused to only one tooth! In the past, if you wanted to see one tooth area, the whole jaw or head had to be x-rayed.

With a cone-beam rather than a medical “spiral CT,” the beam is extremely focused and small. The radiation is minimal and you stand upright for the scan. A medical spiral 3D scan is heavy radiation and you are typically lying down inside of a small tube.  Many patients become claustrophobic of the medical CT tube.

My cone beam machine looks like this and takes most scans in about 30 seconds:

The safety and precision of the 3D scan allows me to do virtual surgery on my laptop before I ever do it in your mouth!  This reduces the number of surprises that can be encountered during surgery. It allows me to see your nerves, bone arteries, sinuses, bone depressions, and every detail down to less than a 10th of a millimeter. The detail of virtual reality is amazing.

Having this technology in the office prevents you from having to drive all over town from the x-ray lab, to the dental implant surgeon, to the regular dentist that will make the tooth. In my office, all of these are in my control, under one roof. This allows me to offer dental implants and teeth safely, at a fair price, and most of all, to do it right.

Another big advantage is often a bone graft can be avoided if a 3D scan is done. Even if the bone is narrow, the trajectory can be changed and/or an angled custom abutment can be used.

A 3D x-ray is not required for all dental implants and bone graft procedures. I asses each patient carefully before recommending a 3D cone beam x-ray. Some patients require two or more 3D x-rays– one before major bone grafting and one after.

Full Mouth Dental Implant Reconstruction -Audio Explanation With Burbank’s Ramsey Amin, DDS

Full mouth dentistry with dental implants and crowns can get very complex.  I treated this patient in my Burbank office with nine dental implants and a total of more than 20 crowns. The full mouth reconstruction involved the upper and lower teeth and opening the bite to be taller.

The three minute audio recording will guide you through the patient’s case from start to finish.

Besides nine dental implants, sinus lift bone graft and bone widening was done.  All work was done while he slept under IV sedation in my office.

The results are dramatic.  Please listen to the audio and look at the pictures, CT scan and x-rays.

Ramsey Amin, DDS – Sinus Lift Bone Graft Case Example For One Dental Implant

This is a very unique case where a large sinus bone graft had to be performed for just one dental implant. This example below was done at my office in Burbank.

The sinus was so expanded from bone loss that an “internal sinus bone graft” would not work.  There was not enough pre-existing bone to do that technique which reduces cost and time.

On a side note, many patients mistake the word “graph” with “graft.”  “Graft” is the proper term for “grafting” bone or tissue such as gums or skin.

Here is how he started with one missing tooth and no bone in the area.  This is a hollow sinus in the area of the upper left first molar #14:


This is what the sinus looks like from the inside from the CT scan. Double click to enlarge the image.


My virtual surgical planning software allows me to do surgery on the computer before the real dental implant or bone grafting procedure.

The purple object is the dental implant plan and the red drawing is how much bone is missing.  That is a lot of missing bone!

Here is the x-ray after the bone graft.  The implant is 16mm long and there is still bone beyond it.  I was able to build about an inch and a half of bone for this patient!

It was allowed to heal for 4 months.


When you look closely at the implant near the top, you can see that the bone is dense near the neck.  Now he can put the tooth on the implant!


Can you see the bone growth?  Feel free to comment below.  No need to sign up!

Dental CT Scans and Bone Width For Implants – Burbank Implant Expert Explains

There’s a good chance I will need to obtain one or more x-rays of your jaw, teeth or facial skeleton at some point during the diagnostic evaluation (or workup) of your bone loss or missing teeth areas.

3D Cone-Beam CT scans allow me to view  bone in a very special way.  What most people don't know is that a regular x-ray can only show how "tall" your bone is; it can not show the "width."  CT or "CAT" scans allow the width to be determined.

These pictures of a real patient that I treated in my office in Burbank should help.  I placed five dental implants in his lower jaw.

So often times a regular x-ray, just doesn't show enough information to safely place a dental implant.  Your bone may "look" wide, but only really be just gums! 

A regular x-ray is a 2 dimensional image while the jaws and facial skeleton are 3-dimensional structures-therefore, they are unable to provide all the information sometimes required. Often times films (or copies of films) from your previous dentist can be utilized without the need for additional imaging; however, please be aware many times these film images are of inadequate orientation or quality.

When an image has been transferred to paper, critical areas of anatomy cannot always be discerned adequately in order to safely plan. Transferring radiographic data from electronic media to paper can result in significant loss of image resolution and clarity. In these cases a new image in my office is typically obtained.

Each patient and area is very unique.  Not all patients need CT scans.

Dental Implant CT Scan Video

The power of interactive CT cone beam scans in implant dentistry is amazing!

It allows me to plan the surgery in advance.  I can see things that I could never see with traditional x-rays. This man from Glendale, California was missing all of his teeth and wore regular dentures.

The CT (CAT) scan allowed the patient and I to really appreciate the bone loss he had suffered due to missing his teeth for so long. A cone beam CT scan exposes you to minimal radiation and maximizes safety.

Four dental implants were placed and an overdenture made for the bottom jaw.  He has been thrilled. Even with his bone as thin as it looks, a bone graft was NOT needed due to planning with a CT scan. He said the bad breath he use to have is much better since the denture does not lift anymore.

CT Scans For Dental Implants

CT Scans are sometimes called ‘cat scans’.

CT scans are often used when having implants that are more complex. A ct scan allows me to see your jaw in 3-D.  The machine used to take the image allows the CT scan to be taken while you sit upright in about 20 seconds.

Regular x-rays are great, but have limitations. I can only see two dimensions. I cannot tell how wide your bone is. I can only tell how tall it is. Looking at the width of the bone in the mouth is inaccurate for areas where the bone is small since the overlying gums may be thick.

The biggest advantage to ct scans is the ability to do "virtual surgery." that means I do surgery on the computer before I ever even touch your mouth! The ct shows the important anatomy, sinuses, nerves and arteries thereby improving greatly safety. Often times I transfer the surgery from the computer to your mouth with special positioning guides.

These pictures are some samples of surgery on the computer.
