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.
The patient is informed of the treatment options available so they can make the best informed choice.
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.
Although a legal and common practice, we never use recycled braces. We feel braces are precision devices manufactured to be in one mouth only!
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.
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.
Our instruments are autoclave sterilized between every patient. Single-use/disposable items are used when possible.
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.
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.
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.
We will always make time to answer your questions.

Earn “gifts” for excellent compliance.
When you enter our office, you will get a feeling of our uniqueness. Much care was taken in the design to make each office visit relaxed and enjoyable-a truly positive experience, it is like entering a Jungle Jim exodus before having your teeth fixed . We also decorate our office with flowers for all flower‘s lover, it is an Ikebana art as many of our staff including doctors are Ikebana art Masters too! Many of the paintings on the wall are painted by Dr Anka!

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.

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.

Short-term, limited orthodontic treatment is available in situations when a patient is unwilling to undergo comprehensive orthodontic treatment but wishes to have minor tooth movement to either enhance their smile or to position a certain tooth prior to the placement of an implant or bridge. Treatment of this nature may be performed with braces or removable
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
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 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.
