Do CBCT scans suffice for design? @Realsurgerymax

[oganthropologist]

Getting cheek implants and Pagnoni mentioned medical grade CT scans are preferred over CBCT scans in order for his designer (presumably Giant @RealSurgerymax ) to design.

Will it ruin the design and, potentially, my face if I opt for the inferior CBCT scan instead?

I know this sounds high inhibition, but my family has a sensitivity to cancer so I'd like to avoid high bouts of unnecessary radiation if possible. If CBCT scans can yield the same results I'll get this done today.

A CT scan is not gonna give you cancer. You need to get referred by a surgeon and that surgeon will tell the imaging clinic what scans you need, so you first need to find a surgeon who is down to just plan with a CBCT, which is technically possible if the fov is high enough.

• Full head CT Scans have slightly less than a 1 in 2,000 risk of causing a cancer later in life. Chest CTs are the highest risk area being over 1 in 2,000.
• That means in the hundreds of patients I have worked with, probably none of them will get cancer (forms the scan) but about 50-100 will develop cancer naturally when they get older.
• Your lifetime cancer risk is already quite high, the CT scan adds a tiny amount.
• That's still not a small risk and CT scans should be done only when needed. In the case of custom plates, guides and implants, its usually needed.

• SOME CBCT scans have a large enough Field of View to contain the whole face/head. most dont.
• SOME CBCT scans are high enough resolution quality but about 75% are not. NEVER use the low-dose quick scan settings.
• Considering most CBCTs are incapable on one or both criteria (Scan resolution and field of view size), a CT is usually preferred

• Ionizing radiation from the CT scan is what causes the DNA damage which leads to delayed cancers.
• Glutathione and Vitamin C IV Infusion can be done before (or during) the CT Scan to theoretically reduce the amount of damage.
• Most places in USA or Europe will not accommodate this. However, its possible in Bangkok, and I can arrange it.

I had this exact question in my head the other day

I guess you are supposed to get into these machines with no metal on you but what about tianium implants?
Do they damage the scan or possess a medical risk?

You are thinking of MRI.

Titanium is technically MRI because it isn't magnetic.

Titanium is fine for CT but produces some artifact/scatter

Informative response thank you. Are there specific instructions or a prescription I can provide the CBCT scan specialists to check if they adhere to? Example what precise field of view, voxel resolution, etc? That would be great.

For example, I was referred to a specialist that can do full 90% of face (up to hairline) field of view, with 0.3mm / 300 µm voxel size.
