Invisalign Treatment Process: Complete Step-by-Step Guide from Start to Finish
A complete walkthrough of the Invisalign treatment process at Hedgewood Dental in Woodbridge, VA. From iTero scan and ClinCheck to fitting, progress visits, and retainers.
You've decided to straighten your teeth. You know Invisalign uses clear plastic aligners instead of metal brackets. But what actually happens between that first consultation and the day you finish treatment? The process is more structured than most people realize — and knowing what's coming makes the whole experience smoother.
Dr. Christine Mai at Hedgewood Dental in Woodbridge has guided hundreds of patients through Invisalign. Here's the complete roadmap.
Phase 1: Consultation and Digital Scan
Your Invisalign journey starts with a complimentary consultation. Dr. Mai examines your teeth and bite, discusses your goals, and uses the iTero scanner to create a precise 3D digital model of your mouth. No goopy impressions. The scan takes about two minutes per arch.
The iTero software generates an Invisalign Outcome Simulator — your first look at what your smile could become. It’s a powerful motivator, and for many patients, it’s the moment they decide to move forward.
Phase 2: ClinCheck Treatment Plan
If you decide to proceed, Dr. Mai submits your scan to Invisalign’s lab. Within about two weeks, your ClinCheck treatment plan arrives — a digital animation showing every tooth movement from start to finish, week by week. You can see exactly how many aligner sets you’ll need and what your teeth will look like at each stage.
Dr. Mai reviews this plan carefully before approving it. She may request adjustments — tweaking the timing of certain movements, adding or removing attachments, or refining the final position. The plan doesn’t go to manufacturing until she’s satisfied.
Phase 3: Aligner Fitting
Two to three weeks after plan approval, your first set of aligners arrives. At the fitting appointment, Dr. Mai places any needed attachments — small tooth-colored bumps of composite bonded to specific teeth. These give the aligners something to grip and are essential for more complex movements. She’ll also demonstrate how to insert, remove, and care for your aligners.
You’ll walk out wearing your first set. They’ll feel snug — that’s the pressure that moves teeth. Most patients adapt to the sensation within a day or two.
Phase 4: Active Treatment
You wear each set of aligners for one to two weeks, depending on your plan, then switch to the next. Unlike braces, there’s no monthly tightening appointment. Instead, you visit Dr. Mai every six to eight weeks so she can check your progress, make sure the teeth are tracking correctly, and give you your next few sets of aligners.
Most cases take 12 to 18 months, though simpler cases can finish in six. The key variable is compliance — aligners need to be worn 20 to 22 hours per day. Patients who stick to that schedule rarely have delays.
Phase 5: Refinement (If Needed)
Toward the end of your initial set of aligners, Dr. Mai evaluates the results. Most patients’ teeth have moved as planned. If a few teeth need additional movement, she orders refinement aligners — essentially a second, shorter round of treatment to fine-tune the result. Refinements are included in the treatment cost.
Phase 6: Retention
When treatment is complete and Dr. Mai is satisfied with the result, attachments are removed and you transition to retainers. You’ll receive custom Vivera retainers, worn full-time initially and then nights only. Consistent retainer use is non-negotiable — without it, teeth naturally shift back over months and years.
Dr. Mai includes retention planning and follow-up monitoring as part of every Invisalign case. Your smile is an investment worth protecting.

Frequently asked questions
Does the iTero scan hurt?
Not at all. The wand never touches your teeth — it captures images from a short distance. There's no radiation, no discomfort, and no gag-inducing impression material.
How many aligners will I need?
It varies by case. Simple corrections might need 10 to 15 sets. More complex cases can require 30 to 40 or more. Dr. Mai will tell you the estimated number during your ClinCheck review.
What if I lose an aligner?
Call the office. If you recently switched to a new set, you may be able to move to the next one early. If not, Dr. Mai can order a replacement. Never go backward — wearing an old set for too long can allow teeth to shift back.
Can I switch to Invisalign if I already have braces?
Yes, in many cases. Mid-treatment transfers are possible. Dr. Mai will evaluate your current progress and map a new Invisalign plan from where you are now.
How often are follow-up visits?
Every six to eight weeks. These are brief — about 15 minutes — to check tracking and dispense your next sets of aligners.
