Services
Colleen Hukowski, Front Desk Administrator, has been with Dr. Antonellis for over 30 years. Our patients are greeted by Colleen's warm and friendly smile when they first walk in the door. She schedules patient appointments, handles payment and coordinates all insurance.

Your first visit to our office is complimentary. When you call to make your consultation appointment, the staff will ask you for some basic information to register you as a patient in our system. When you arrive, you'll be asked to complete a medical history for yourself or your child. This will assist the doctor with understanding your specific health profile, as well as providing additional information to add to the patient record.
This first appointment usually includes two x-rays to assist the doctors in working up your specific treatment plan. The panoramic radiograph is a frontal view and the cephalometric radiograph is a side view of your teeth and jaw. Patients are protected with a lead vest to minimize exposure. We utilize state of the art technology to complete a 3-D digital scan of your teeth.
Once your orthodontic hardware has been placed, you'll need to return for follow-up adjustment appointments approx 4-6 weeks apart. These appointments will continue as you progress through orthodontic treatment. To accommodate school and other lifestyle activities, adjustment appointments can be scheduled after school or in the evening.
The American Association of Orthodontics suggests a first visit to the orthodontist by the age of seven. Starting the process early doesn't always mean a child will require treatment right away. It simply allows the orthodontist to evaluate and recommend the best timing for treatment.

If your child is experiencing crowding of teeth, difficulty chewing or biting, mouth breathing or thumb sucking, we encourage you to schedule a free consultation with our office.Braces have become more stylish, even a right of passage, for most teens these days. The variety of styles, materials and colors make brace wear easier and more comfortable than in the past.

Dr.Antonellis and the staff at Montville are absolutely amazing, very professional!.
They are so well accommodating from making appointments to just making my children feel comfortable. We have been going to him for years now and never had any issues. Ever! They take us at our scheduled appointment time, hardly a wait. The staff make my children feel comfortable,everyone is very gentle,they have great communication and never in a rush. My kids were so scared to go at first but now having gone they now look forward to the visits. On our way to a perfect SMILE! Very excited!

I had my lower braces taken off today. I'm relieved and happy my orthodontic treatment is over today. My teeth are very very straight and look like have never before! I only regret not having them earlier in my teens. It was not the most painless experience in my life, but for an appealing and a beautiful smile it's absolutely worth! The assistants at Dr. Peter Antonellis office are extremely pleasant and professional specialists. They always explained everything about my ortho treatment. The only thing I would suggest to improve is for Dr. Antonellis to explain on-the-spot process more.

I have been a patient of Dr. Antonellis for years. I cannot say enough how wonderful the practice is. The doctor is top notch- professional and wonderful at what he does. He truly cares about his patients and I am incredibly happy with the results. Everyone, including the staff, is courteous and caring. Well done Montville Ortho!

Run, I have received $4,210 of invoices that Montville Orthodontic Associates said that I owe, I have called them twice and they will not speak with me about this bills. I have never been in their office and I never heard of their company until I received these bills. I am expecting collections to contact me next based on the unethical rude behavior. I know it tough times but this is ridiculous.

I have had nothing but positive experiences with Dr. Antonellis and his staff.
They've treated me with a courtesy and professionalism not easily found nowadays.
The office and chairside staff are terrific people and always helpful.
I would recommend the office to anyone.
