An Invisalign consultation is the first step toward straighter teeth and a corrected bite. It is a focused appointment where a specialist orthodontist discusses your concerns, reviews your dental history, and identifies the functional and aesthetic goals that matter most to you. No scanning or X-rays are taken at this visit — diagnostic records are collected at a separate records appointment, and a detailed ClinCheck 3D treatment plan is reviewed with you at a planning appointment. At DenCos in Hoofddorp, consultations are performed by Dr. Jing Guo (BIG 19918762902) — a registered specialist orthodontist, Invisalign Diamond Apex provider (top 1% in Europe), and one of only 5 certified Invisalign mentors in the Netherlands.
This article explains exactly what happens during the consultation, what follows in the records and planning stages, how to prepare, and what information you will leave with.
What happens during an Invisalign consultation?
The first consultation at DenCos is a focused conversation — approximately 20–25 minutes — designed to understand your situation and goals before any clinical records are taken.
Step 1: Discussion of concerns — Dr. Guo listens to what bothers you about your teeth or bite, whether that is crowding, spacing, an overbite, crossbite, or purely cosmetic alignment. She asks about any symptoms such as jaw discomfort or difficulty chewing.
Step 2: Dental history review — Dr. Guo reviews your dental history, including any previous orthodontic treatment, relevant medical conditions, and your general dentist's findings. If you have brought recent X-rays or records, she reviews those too.
Step 3: Identifying goals — together you discuss the functional and aesthetic goals that matter most to you (or your child). Dr. Guo gives an initial indication of whether Invisalign, fixed braces, or a combined approach is likely to be most suitable, and explains what the next steps involve. For adult patients, periodontist Dr. Gang Wu (BIG 29918905102) may also be consulted if gum health is a factor — a unique advantage of DenCos's interdisciplinary model.
At DenCos, you are never pressured to decide on the spot. The consultation is purely informational — no scanning or treatment is performed at this appointment.
What happens after the consultation?
If you decide to proceed, the next steps follow a structured path:
Records appointment — digital photographs (intraoral and extraoral), X-rays (panoramic and cephalometric where indicated), and an iTero 3D digital scan are collected. These diagnostic records document your starting position and allow Dr. Guo to assess root health, bone structure, and jaw relationship in detail. The iTero Outcome Simulator may also show a preliminary preview of your potential smile transformation at this point.
Planning appointment — Dr. Guo develops a detailed ClinCheck 3D treatment plan using your diagnostic records and walks you through it: the predicted tooth movement, number of aligners, estimated treatment duration, a personalised cost estimate including retainer options, and insurance coverage where applicable. You approve the plan before any aligners are manufactured.
What is an iTero 3D scan and why does DenCos use it?
The iTero is a digital intraoral scanner manufactured by Align Technology — the same company that produces Invisalign. It replaces the uncomfortable putty trays used in traditional dental impressions with a small, handheld wand that scans your teeth and gums optically.
Key advantages of iTero scanning at DenCos:
- Comfort — no gagging, no messy impression material, no waiting for trays to set
- Speed — a full-arch scan takes approximately 5 minutes
- Accuracy — digital scans produce a clinically precise 3D model that feeds directly into ClinCheck treatment planning. A comparative study published in the Journal of Advanced Prosthodontics confirmed that intraoral digital scanning achieves comparable or superior accuracy to conventional impressions for orthodontic purposes.
- Instant visualisation — you can see the 3D model of your teeth on screen immediately after scanning
- Outcome simulator — the iTero Outcome Simulator can show a preliminary preview of your potential smile transformation before a full ClinCheck plan is generated
At DenCos, Dr. Guo uses the iTero scanner for every Invisalign case. With over 3,000 cases scanned and treated, DenCos's Diamond Apex Status reflects both the volume and precision of its digital workflow.
How does ClinCheck show your treatment result?
ClinCheck is Align Technology's proprietary 3D treatment planning software. It creates a virtual model of your entire Invisalign treatment — aligner by aligner — showing exactly how each tooth will move and when.
At the follow-up planning appointment, Dr. Guo walks you through the ClinCheck plan:
- Current position → final position: see your teeth transform step by step on screen
- Treatment stages: each aligner stage is mapped, showing the precise movement per tooth
- Timeline: the total number of aligners and estimated treatment duration are displayed
- Before/after comparison: overlay views let you compare your starting alignment with the predicted result
What makes Dr. Guo's ClinCheck plans different from those of general dentists offering Invisalign? Her Diamond Apex experience (top 1% in Europe, 3,000+ cases) means she understands the biomechanics of each planned movement. She adjusts attachment placement, staging sequences, and force distribution based on clinical experience — not just the software's default suggestions. This precision reduces refinement rounds and keeps treatment on schedule.
The ClinCheck plan becomes your treatment roadmap. At DenCos, you approve the plan at the planning appointment before any aligners are manufactured. Many patients discuss the ClinCheck plan with their family before giving the go-ahead.
Do you need a referral to book a consultation?
No referral is needed. In the Netherlands, you can book an appointment with a specialist orthodontist directly. At DenCos, you can:
- Call 023-792 0463 to schedule your consultation
- Register online at DenCos new patient registration
Both adults and children are welcome. If you have been referred by your general dentist, bring the referral letter — but it is not required. DenCos serves patients from Hoofddorp, Haarlemmermeer, Haarlem, Amsterdam, Amstelveen, Aalsmeer, Heemstede, Bloemendaal, Leiden, Noordwijk, Velsen, Lisse, Uithoorn, Zaanstad, and the wider region.
Appointments are available until 18:30 on Tuesday to Thursday — convenient for patients who work or attend school during the day.
How should you prepare for your consultation?
Preparing for your Invisalign consultation is straightforward. Here is what to do before your appointment:
- Brush and floss your teeth before arriving — a clean mouth allows for a better clinical examination
- Bring dental records if you have recent X-rays or treatment records from your general dentist (not required, but helpful)
- Bring insurance details — if you have dental insurance that covers orthodontics, bring your policy information so DenCos can check your coverage and estimate out-of-pocket costs
- Prepare questions — write down anything you want to ask about treatment duration, cost, alternatives, or daily life with aligners
- Arrive 10 minutes early — to complete any intake paperwork if you are a new patient
No special dietary restrictions or medical preparation is needed. The consultation is non-invasive — no treatment is performed at this appointment.
At DenCos, Dr. Guo takes the time to answer all your questions. Whether you are considering Invisalign for an overbite, crossbite, crowding, or cosmetic alignment — the consultation is designed to give you clarity and confidence in your decision.
What information do you leave the consultation with?
After the first consultation at DenCos, you walk away with:
- A clear understanding of your orthodontic concerns and what you want to achieve
- Dr. Guo's initial assessment of whether Invisalign, fixed braces, or a combined approach is likely most suitable
- An explanation of the next steps — the records appointment (photographs, X-rays, iTero 3D scan) followed by a planning appointment where you review the full ClinCheck treatment plan, cost estimate, and insurance coverage
- Confidence that you have spoken with a registered specialist orthodontist who has treated 3,000+ cases
This structured approach — consultation first, then records, then treatment plan review — ensures every decision is made at the right time with the right information, and with no obligation to proceed.
