You are cared by two doctors

The benefit of having two doctors in the office is tremendous. Although Dr. Anka and Dr. Aonuma have very similar treatment philosophies, the doctor's routinely confer with each other to establish definitive treatment plans in their patient's best interest.

All options of treatment are presented

The patient is informed of the treatment options available so they can make the best informed choice.

Parents are informed of treatment progress at each appointment

We make a conscious effort at every appointment to update you on treatment and if it is progressing according to schedule. We are committed to keeping you informed and we will always make time to answer your questions.

We do not use recycled braces or bands that were used in someone else's mouth!

Although a legal and common practice, we never use recycled braces. We feel braces are precision devices manufactured to be in one mouth only!

Treatment is completed within the estimated treatment time.

We have a very high success rate of completing treatment within the estimated treatment time. We pay close attention to the best time to initiate treatment and make sure not to start a child's treatment too early. Efficient systems are in place to help ensure that treatment is completed on schedule with the best possible result.

Up to date sterilization systems are in place.

Our instruments are autoclave sterilized between every patient. Single-use/disposable items are used when possible.

State-of-the-art appliances bring our treatment to a new level of clinical performance.

  • Our clear brackets are virtually invisible and are designed to move the teeth efficiently. White coated wires are available as well.
  • Nickel-titanium arch wires create a continuous-light force resulting in more efficient tooth movement with less discomfort to our patients.
  • Invisible Clear Aligner is one option for adult patient who wants unseen bracket (clear and removable). The appliance can be also use in conjunction before fixed appliance to reduced the show up brackets time.
  • Consequently treatment is completed more quickly with a more ideal occlusion (bite).
  • The majority of orthodontic relapse occurs along the lower front teeth and is usually caused from poor cooperation using a lower removable retainer. As a result we almost always recommend a permanent retainer on behind the lower front teeth. They are not visible and comfortable to wear. We will discuss with each patient a definitive retention plan tailored to their individual needs as treatment comes to completion.


Treatment is tailored to each patient's individual needs.

Care and consideration is taken by the doctor and staff to treat each patient as an individual and not a "cookie cutter" treatment approach where every patient receives the same treatment modality regardless of their chief reasons for seeking orthodontic care.

A commitment to communication at each visit.

We make a conscious effort to update you about you or your child's treatment at every appointment. With daily "appointment summarys" and periodic formal progress reviews, patients and parents are kept abreast about treatment and if it is progressing according to schedule.

Our secretary will take your phone calls in English

We will always make time to answer your questions.


Adults Orthodontic Treatment

Adults Orthodontic Treatment

Adults Orthodontic Treatment

Many of our patients are adults. The office has been designed taking into consideration the specific needs of adult patients. In each office, specific treatment areas were created to allow for more privacy. Treatment planning of adult patients differs from that of child patients. Treatment modalities have been created to minimize visits while maximizing efficiency to accommodate an adult's busy schedule.

Most adults choose to use clear braces that are virtually invisible or lingual orthodontic braces, or the combination of both. Our retainer is a clear plastic and/or lingual fixed retainer that is totally invisible.


Good News for Mild Skeletal Problem Patients!:

The use of TADs or Temporary Anchorage Devises has been tremendously advance as to be able to handle many of the Dental Alveolar Deformity as it is possible now to do Dental Alveolar Orthopedic Treatment more than ever in history of Orthodontic Treatment. This new technology means that it is possible to correct patients who do not like to under go Surgery and therefore Camouflage Treatment is possible with orthodontic alone. For details please consult us, one of the pioneer in the field. We take pride of this innovation as we also an Advisor Member of the WIOC (World Implant Orthodontics Conference) a world wide organization recognized by WFO (World Federation of Orthodontics). The American Orthodontics Association is also belongs to WFO.


Surgical Orthodontic Treatment

Approximately 5% to 7% of the United States population is believed to have skeletal facial deformities resulting in jaw malrelationships. Often in these situations, orthodontic treatment alone may provide an unstable and unpredictable solution to a severe malocclusion (bad bite relationship) and the result may be significantly compromised. Therefore, orthodontia, in conjunction with jaw surgery may be necessary to achieve a proper result. Following are different skeletal irregularities that orthodontics in conjunction with orthognathic surgery can address to improve the ability to chew, speak, breathe and in many cases enhance appearance.

Orthodontic and oral surgery team approach

Orthodontic and oral surgery team approach
Treatment is initiated by the orthodontist. Dr. Anka and Dr. Aonuma job is to properly align the teeth so that when the jaw is surgically moved the teeth will fit together properly. After the surgery further orthodontic tooth movement is necessary to finalize the result. Although for every patient the timing of treatment is different, a common scenario is as follows: 1. 6-12 months of presurgical orthodontic treatment 2. Orthognathic surgery procedures 3. 6-12 months of post-surgical orthodontic treatment.


Since the introduction of orthognathic surgery more than 25 years ago in our office, there has been a continous trend toward improvement in techniques and materials. If indicated, orthognathic surgery can be an optimal way to correct a specific dysfunction as well as give the patient an overall improvement in the quality of life.


The Process is smooth!

The new technology of TADs has eliminated the wear of HEADGEAR! Less extraction!

Dr. Anka is a Board Certified Specialist in Orthodontics . The National Board member is only around 300 within 6000 of Japanese Orthodontics Association. Not every orthodontist undertakes this rigorous, lengthy and ongoing examination process leading to Board Certified status. This is an honorable endeavor that allows Dr. Anka to pursue a mission as : to establish and maintain the highest standards of clinical excellence in orthodontics.

In our office you do not have to worry about pain and the treatment is definite progress to our common goal to give you the best smile in town. Your treatment will be an rewarding as well as an exciting one as you see how your teeth move without any pain! Your electrical smile is awaiting!
