Nearly invisible
Clear trays that most people never notice — no brackets, no wires, no metal smile in photos.
Straighter teeth, without the braces
Clear, removable aligner trays that move your teeth gradually — fitted and supervised in person by Dr. James Chon, DMD. We offer both Invisalign® and OrthoFX.
At In Line Dentistry in Diamond Bar, Dr. James Chon, DMD, straightens teeth with Invisalign and OrthoFX clear aligners, and mainly uses OrthoFX. It starts with a free consultation, where he checks whether aligners suit your bite and gives you an itemized written quote for the full treatment before anything begins.

Invisalign or OrthoFX?
We fit both — here's how we choose
Invisalign® is the best-known clear-aligner brand; OrthoFX is the other system we fit, and the one Dr. Chon mainly uses. Both work the same way — clear, removable trays, planned digitally and supervised by your dentist at every step. Dr. Chon recommends one or the other based on how far your teeth need to move and how your bite behaves, not on which box it comes in. You get that recommendation, and the reasoning behind it, at the free consultation.
Removable
Take them out to eat, brush, and floss. No food restrictions, no cleaning around hardware.
Doctor-supervised
Dr. Chon plans your case, fits your trays, and checks progress in person — not an app, not a mail-order kit.
Honestly priced
Your complete cost in writing at the exam, before anything starts — the number you see is the number you pay.
How it starts
One free visit answers everything
Whether aligners fit your case, how long treatment would take, and exactly what it would cost — all of it comes out of one free consultation with Dr. Chon. If aligners aren't the right tool for your bite, we'll tell you that too, and show you what is.

Clear aligner questions
Clear-aligner questions, answered
Is In Line Dentistry an Invisalign provider in Diamond Bar?
Yes. Dr. Chon offers Invisalign® and OrthoFX clear aligners at the Diamond Bar office. The consultation includes a digital scan, he tells you which system fits your case, and you get the full price in writing before anything starts.
Do you offer Invisalign?
Yes. In Line Dentistry fits Invisalign®, and we also offer OrthoFX, the system Dr. Chon mainly uses — both are clear, removable aligner systems that move your teeth gradually. Dr. Chon plans and supervises either one in person. Which system suits you depends on how your teeth need to move, and that is what the free consultation determines. You leave knowing which we recommend for your case and exactly what it costs.
How much do clear aligners cost in Diamond Bar?
Aligner treatment genuinely varies with how far your teeth need to move, so we don't publish a one-size number — you get an itemized written quote at your exam before anything starts, and the number you see is the number you pay. The consultation itself is free.
How do clear aligners work?
You wear a series of custom clear trays, each one moving your teeth a small step. The trays are removable — you take them out to eat, brush, and floss — and nearly invisible while you wear them. Dr. Chon checks your progress at short visits through treatment.
Am I a candidate for clear aligners?
Aligners handle most mild-to-moderate crowding, gaps, and teeth that have shifted after braces. More complex bite problems sometimes need a different approach — that's exactly what the free consultation determines, so you know your real options before committing to anything.
How long does treatment take?
It depends on how far your teeth need to move — simple cases finish faster than bigger corrections. Dr. Chon maps your expected timeline at the consultation, so you start with an honest estimate instead of a guess.
When can I come in?
Dr. Chon sees patients on Tuesdays, 9 AM to 6 PM, and Thursdays, 10 AM to 7 PM. The office answers calls and handles scheduling Monday through Saturday — book your consultation for a Tuesday or Thursday.
