Is it true that CT scan is necessary before a dental implant or bridge?

Not always . But with that said a ct scan offers much more 3d info than a 2d peri apical or panoramic. Depending on the extent and location and number of implants being placed, a ct scan can offer tremendous benefit. Hope this helps.
Not true. Scans are necessary when there are problems with anatomy. That is if there is not enough bone below your sinus or above your mandibular nerve. Also if the bone is too thin to properly accommodate an implant if you see a very experienced implant doctor they will not use a scan on every patient.

Is CT scan necessary for dental implant or bridge? Please advise!

Yes for implant. It is necessary when having an implant placed for the dentist to get a CT scan in order to evaluate the amount and position of the bone the implant is to be placed in. Dental x-rays are also needed, but in the case of a fixed bridge, only x-rays are needed to determine the stability of the teeth that will be the anchor teeth to hold the bridge in. If possible, go with the implant. Good luck. Read more...
Can be. The use of a CT scan is helpful in many cases and situations, but not yet required as "customary" of yet mandated as "standard of care". If there is any concern about the volume, location, and dimensions of the anchoring bone, then CT scan is advised. Sinus and Nerve location are critical. We use on all patients at By Design Dental Implant Center. Good Luck with your treatment. Read more...

Should I do & how much radiation CT scans for one dental implant causes vs regular chest/head CT scan or one digital tooth x ray. I am curious to know

Should you do ? Answer is yes, if your surgeon is requesting digital images of your surgery site. The amount of radiation is least for a single dental film, and obviously more for a scan that has to pass through more tissue. What you must remember is that the dosage is of diagnostic strength, not occupational exposure. Millions of images have been taken without a problem. Read more...
Radiation dose chart. We only want to take the minimum number and type of x-rays or scans in order to properly diagnose and treatment plan. Without that we might either miss something or the final result might be compromised. Here is a good website for you to look at: http://www.Ans.Org/pi/resources/dosechart/. Read more...
The largest 200 mrem. The largest does listed for a CBCT scan of the head of 200 mrem. This is about the same amount of radiation you get from natural radon (flight from Los Angeles to New York). Read more...

A 3d CT scan of the jaw shows just enough height and width for dental implant. Does it also show the bones hardness to dds where the implant would go?

Most of the time. Depending on the type of software that your dental provider is using most of the time it is possible to determine the bone density in the site of the implant as well. These are called hounsfield units. Read more...
The short Answer, NO. You have been doing your home work, and while the height and width of the bone can be clearly seen, its density can only be guessed at by a comparative assessment. The experienced surgeon is able to make a pretty good guess, but every now and then they do have surprises. Read more...

For Dental implants evaluations, do you really need CT Scan. Any concerns from using CAT Scan – Kodak 9500 Cone Beam Scanner. How much radiations?

Depends. Many surgeons work from panoramic and PA single images with great success, precision and safety. However, for more complex applications around the sinus and inferior alveolar nerve areas, the 3D scan is the standard for safety and accuracy. Even then, we see differences once we clinically visualize the bone. Radiation exposure is less than you might think as it is quickly completed. Good Luck. Read more...
