The consultation and CBCT scan: where full-arch begins

Every good full-arch result is built long before any surgery — at a consultation and a scan that most patients underestimate. This is not a sales appointment; it is where your entire treatment is designed and where an honest surgeon decides whether to proceed, prepare, or advise against. Understanding what happens here helps you show up as an informed partner rather than a passive patient, and it takes a lot of the fear out of the road ahead.

The conversation and the exam

The visit usually begins with a conversation, because full-arch is as much about your life as your mouth. Your surgeon will want to understand what is bothering you now — loose teeth, failing bridgework, an ill-fitting denture, pain, difficulty eating — and what you want your smile and function to feel like on the other side.

Then comes the clinical exam. Your surgeon looks at your remaining teeth, the health of your gums, your bite, and the general condition of your mouth. They will also review your medical history carefully. This matters more than people expect: conditions like uncontrolled diabetes, certain medications, heavy smoking, or a history of head-and-neck radiation can affect healing and planning. Being open here is part of getting a safe result — nothing you share is a judgment, it is information your surgeon needs.

The CBCT scan: seeing in three dimensions

The centerpiece of the visit is the CBCT scan — cone-beam computed tomography. In plain terms, it is a quick, painless 3D X-ray that produces a detailed, three-dimensional picture of your jaw. You sit or stand while the machine rotates around your head for a few seconds. It uses a low dose of radiation, and the payoff is enormous: your surgeon can now see the exact shape and volume of your bone, and — critically — the two structures a full-arch plan must respect.

The maxillary sinus, the air space above your upper back teeth, which limits how and where upper implants can be placed.
The inferior alveolar nerve, running in a canal through your lower jaw, which must be given a safe margin.

A flat, two-dimensional X-ray simply cannot show these relationships accurately. The 3D scan is what turns implant placement from an educated guess into a precise, planned procedure — and it is the same scan that feeds the robotic, Yomi-guided plan used in surgery.

Turning the scan into your plan

With the scan in hand, your surgeon designs the plan. For a full arch, this means deciding:

How many implants your case needs — commonly four to six per arch.
Where each one goes, at what angle, and to what depth — often tilting the back implants to capture more solid bone and steer clear of the sinus or nerve.
Whether any preparation is needed first, such as removing failing teeth, or, less often, grafting bone or a sinus lift.
Whether same-day teeth are realistic, which depends in part on your bone quality and how firmly implants are expected to grip.

This plan is the blueprint the whole journey follows. At myFullArch, it is also the digital plan the surgical robot uses to keep placement precise on the day.

The honest candidacy conversation

A consultation worth trusting includes a frank assessment of whether full-arch is right for you, and whether you are ready now. Modern protocols have widened the door considerably — tilted implants and full-arch designs make it possible to treat many people who were once told they had too little bone. But “widened” is not “unlimited.” If you genuinely need preparation first, a good surgeon will say so rather than rush you.

You should leave understanding three things: whether you are a candidate, what the recommended approach is, and a transparent estimate of the treatment and its cost. If any of those are vague, it is fair to ask for clarity.

Questions worth bringing

Come prepared. Reasonable questions include: How many implants do you recommend for me, and why? Will I get same-day teeth, and what determines that? What sedation options fit my case and health? Do I need any teeth removed or any bone work first? What is the full timeline and the transparent cost? Is robotic guidance right for my case, and if not, what would you use instead?

The bottom line

The consultation and CBCT scan are where full-arch truly begins. The conversation and exam establish your goals and health, and the 3D scan reveals your bone and the sinus and nerve your plan must respect — turning implant placement into a precise, designed procedure. It is also where a trustworthy surgeon honestly tells you whether you are ready now or need a little preparation first. This is general education, not personal medical advice; your surgeon’s assessment of your specific anatomy and health always governs your plan.

Common questions

What is a CBCT scan and is it safe?

CBCT stands for cone-beam computed tomography — a 3D X-ray that produces a detailed picture of your jawbone and the structures around it. It uses X-rays, so it involves a small radiation dose, but the amount is low and the scan is quick and painless. Because it shows the sinus and nerve in three dimensions, it lets your surgeon plan implants safely and precisely in a way a flat X-ray cannot.

What if the scan shows I don't have enough bone?

That is common and usually not a dealbreaker. Full-arch protocols are designed to use the bone you have, sometimes by tilting implants to capture more solid bone. If more bone is genuinely needed, options like grafting or a sinus lift can be planned. An honest surgeon will tell you clearly whether you are ready now or need preparation first.

Will I get my full plan and cost at the consultation?

Often you will get the outline — whether you are a candidate, the recommended approach, and a treatment and cost estimate. Some details are finalized after the scan is fully analyzed and your plan is designed. Ask for a transparent breakdown so you understand what each part of the treatment involves and costs.
