The Invisalign system is an orthodontic treatment that utilizes clear aligners as a non-obtrusive solution for straightening teeth and providing beautiful smiles. We have certified Invisalign providers on our team, and we have completed over a hundred cases. Our entire clinical team is trained to use iTero® Smile Scanning technology to provide Invisalign smile simulations. Call to meet with Dr. Peter Kim or Dr. William Altig!

Why Invisalign aligners?

Invisalign clear aligners are an effective and efficient way of correcting smiles. Dealing with the wires and bands of braces can be irritating and painstaking. With the Invisalign system, there is no obstruction to your current smile, and virtually no one will notice. Invisalign is the option that caters to your lifestyle.

  • Discreetness – Invisalign clear aligners are practically invisible when they are worn! You might even forget they are there!
  • Comfort – Invisalign clear aligners are engineered with a special plastic made as smooth as possible, an exceptionally comfortable alternative to metal brackets and wires.
  • Freedom – Wearing your clear aligners as much as possible helps speed up your treatment, but when you need to, they are easy to remove for a dinner date, brushing and flossing or any other occasion. There are no glue-on brackets or wires that are difficult to brush and floss around. Continue the life you love while gaining a perfect smile!
  • Measurable Results – Even before you finish the entirety of your realignment, you can notice the difference in your smile. Throughout the time of your treatment (typically a year) you will see your smile improve from visit to visit.

How do I start?

The first step towards correcting the alignment of your teeth is coming in for a consultation with our practice. A member of our team will then take a scan of your teeth with our iTero Element Smile Scanner, then our dentists will create a simulation of your dream smile. This simulation will be emailed to you after your consultation for your records as well.

The Process

The needs of every patient are different. Invisalign treatment cases at Sierra Oaks Dental are generally categorized under two different plans: comprehensive and express cases.

Comprehensive cases can take anywhere from 12 to 24 months or more; express cases typically take six months but can take as long as one year. The length of the process is determined by the patient’s needs and is also dependent on the patient’s consistency and dedication with wearing the correcting trays.

Throughout Invisalign treatment, you receive a new set of clear aligners at our office about every two to three weeks. Each set of trays makes micro shifts in the alignment and positioning of your teeth, just the same as bracket braces. Express cases can take anywhere from five to 14 sets of trays, and comprehensive cases typically take 14 sets of trays or more.

Invisalign vs. Alternatives

There are many options for people seeking orthodontic treatment nowadays. From bracket braces to do it yourself at-home invisible trays, there is a lot to consider.

Bracket braces are the oldest form of orthodontic correction and are commonly utilized for children. Having metal brackets adhered to each tooth along with wires and rubber bands can be really obstructive to a person’s smile. Invisalign clear aligners are a clear superior in terms of aesthetics, since the invisible trays are, well, invisible.

Bracket braces can also not be removed for photographs, interviews and other life events. The metal used in bracket braces can scratch at the soft tissue of a patient’s lips and cheeks and can also pose risks of injury or causing discomfort in the mouth. This is especially true for children or adults who play any form of contact sports where there is a chance of impact to the mouth area.

DIY at-home invisible trays are the latest in orthodontic correction treatment, and there are many companies jumping on this fad. DIY trays typically cost less than any orthodontic treatment that you would receive in a clinical office. These DIY programs rely on the patient to take their own impression of their teeth to start the process. But taking impressions of arches (upper and lower sets of teeth in a patient’s mouth) is a skill that takes months and even years to master as a dental assistant.

In addition, any changes to your trays and checkups for your orthodontic treatment require you to video conference a distant, unknown dental professional, but it is next to impossible to provide adequate clinical treatment on someone’s mouth without viewing them in person. Because of this format, there is no backup plan for any issues with the treatment process, except to contact your local dentist. And if you are going to have to do that anyway, why not have them help through the entire process? In many ways, DIY straightening trays are actually much more of a hassle and risk than clear aligners provided by a professional dental practice.

Whitening Bonus

Not only can we correct the alignment of your teeth, but we can also whiten your teeth in the process! Our patients at Sierra Oaks Dental are also eligible to receive professional whitening gel to be used with their clear aligners. It is an unintentional benefit that Invisalign trays are also able to be used as whitening trays, but one our patients welcome!
