  • Average cost ranges from $2000 – $4000 CAD.

  • The average treatment can take approximately 6-16 weeks, but varies on a case by case basis.

  • The inner and outer bows create opposing forces, guided by nickel titanium coil springs to move teeth into alignment.

  • The light but continuous pressure move teeth quickly and has not been shown to cause root resorption when worn for a maximum of 20 hours a day.

(Onenetdesign, 2012, Introduction)


  • To correct mild to moderate crowding of the anterior teeth.

  • Retreatment after orthodontics.

  • Before other cosmetic procedures, such as veneers, to enhance results and reduce the amount of tooth surface removed during preparation.

Inman Fixed Spring Aligner
  • If your client has trouble wearing the aligner on a constant basis or always forgets to wear the appliance, a more permanent solution is available. Bands are fastened to the molar teeth to hold the aligner in a fixed position, reducing client compliance issues.

Invisible Inman Aligner

Figure 3. Invisible Aligner

  • If your client is self conscious about the appearance of the appliance, a virtually invisible option is available. The facial portion of the device consists of a clear acrylic shell that covers the teeth, replacing the metal fixtures of the original Inman Aligner. The disadvantage to this system is that it is only capable of lingual to labial movement because the outer acrylic tray is stationary.

Figure 4. Fixed Habit

  • This fixed appliance is designed with a lingual guard to break thumb sucking or tongue thrusting habits, while also moving facially displaced teeth back into alignment.

Inman Bonded Cross-bite Appliance

  • This fixed aligner specializes in moving the incisors forward to eliminate cross bite in the anterior region of the mouth.

(Great Lakes Orthodontics, n.d.)

  • Cost effective – less expensive than conventional full mouth orthodontics.

  • Less destructive than other cosmetic procedures.

  • Less invasive than full mouth orthodontics because it can be removed at any time.

  • Duration of treatment is significantly reduced when compared to traditional orthodontics.

  • Increased client comfort over conventional orthodontics.

  • Only requires one appliance that can be adjusted to adapt to the teeth as they move into position.

(Inman Aligner, 2012, Top 10 reasons); (Inman Aligner, 2012, FAQs)
  • The device impairs speech, but should improve with time.

  • In certain circumstances, the removal or “shaving down” of tooth structure may be necessary to properly align the teeth.

  • As with orthodontics, discomfort associated with movement of the teeth and the feeling of loose teeth may also be experienced.

  • Requires placement of a lingual wire in order to maintain tooth positioning post treatment.

  • This device only corrects mild to moderate malocclusion in the anterior area of the mouth, therefore if more comprehensive treatment is required, a referral to the orthodontist may be necessary.

  • The Inman Aligner will not correct diastemas seen in the anterior region unless the spacing results from rotation or flared out teeth.

  • Canines are not effectively repositioned and therefore the device is only beneficial for movement of the incisors.

(Inman Aligner, 2012, FAQs); (Inman Aligner Guide, 2012); (Qureshi, 2008)

Client Education_.png
  • At the first appointment, impressions will need to be taken to fabricate the appliance, closely followed by a second appointment to insert and evaluate fit.

  • Clients will need to visit the dentist every 2-3 weeks to have the appliance evaluated and tightened.

  • Results are typically seen between 6 and 18 weeks but only the dentist will be able to determine an accurate time frame.

  • A retainer or lingual wire will be required to maintain tooth positioning after the treatment is complete.

  • Cost will typically be less that conventional orthodontics, but will depend on the severity of the case. The range typically seen is between $2000-4000 CAD.

  • Clients will experience discomfort, similar to braces, especially following adjustment appointments.

  • Speech may be difficult, but should improve over time.

  • In order for the treatment to be successful, the client needs to dedicate 16-20 hours a day to wearing the appliance.

  • Removing the appliance for 4 hours a day during eating and cleaning is important to ensure safety and reduce risk of root resorption.

  • Remind the client that the teeth and appliance should be thoroughly cleaned before placing the aligner into the mouth and after removal.

  • Clients should be aware of the limitations of the device (please see Disadvantages section)

  • “All orthodontic treatment can carry risks but so far in over 20,000 cases there have been no reported instances of loss of tooth vitality or root resorption.”

  • If your client has an unmet need for wholesome facial image due to dissatisfaction with the appearance of tooth alignement, the Inman Aligner may be suggested as an alternative option to conventional orthodontics or other cosmetic procedures.
  • Ensure client has all necessary information regarding advantages, disadvantages and what to expect from the appliance.
  • Educate client on plaque and bacteria accumulation on the device and methods to safely clean the appliance.
  • Provide information regarding various products available to aid in cleaning of the device, such as a denture brush or mild cleaning solutions. A guide on cleaning and care of the device can be found Here.
  • Discuss the importance of diligent oral health care, including brushing and flossing techniques, to maintain periodontal health during treatment. The client must be aware that inorder to achieve optimum results, meticulous home care is imperative.
  • Assess periodontal health throughout treatment and address any concerns the client may have.
  • To maintain satisfaction following treatment, oral self care techniques should be reinforced.
  • Since a retainer or fixed lingual wire is generally required following treatment, education and demonstrations of cleaning and care will need to be addressed.

For Providers_.png
  • Typically, the mandibular anterior teeth are easier to correct than the maxillary anteriors due to the relatively flat lingual surface of the mandibular teeth. It is important to allow for additional time when estimating treatment times for maxillary cases.

  • A small ledge made of composite may be required on the lingual surface of the maxillary teeth to prevent the bow from slipping off the cingulum and onto the incisal portion of the tooth.

Figure 10. Composite Ledge

  • Simple cases that involve lingual or labial tipping of the incisors are the simplest and fastest cases to treat and typically take between 6 to 12 weeks to complete.

Screen Shot 2012-06-23 at 9.45.38 PM.png
Figure 11. Simple cases
  • Moderate to extreme cases involve rotations of the teeth and can take approximately 8-24 weeks to obtain results.

Screen Shot 2012-07-01 at 1.17.24 PM.png
Figure 12. Moderate to Severe Cases

  • If there is inadequate room, small crowns, facially protruded teeth or misaligned canines, the results will be greatly reduced. These situations pose the greatest challenge to treatment.

  • In order to provide the Inman Aligner to clients, no orthodontic experience is required, dentists are only required to take an online certification course and a one-day hands-on course. This information can be accessed by clicking on the following links:

Inman Aligner Dentist Area or Inman Aligner Online Course Information

  • Practitioners who offer the Inman Aligner have access to a program called spacewize. This program calculates the degree of difficulty based of rotation and positioning of the teeth and determines if a referral to an orthodontist is required. These findings can be printed out for the client or included in the clients chart.

(Inman Ortho, 2007); (Inman Aligner, 2012, Top 10 reasons)

Step by Step

  1. Assess the severity of the case.

  2. Provide information regarding the Inman Aligner as well as alternative options, such as fixed orthodontics or clear aligners, and allow the client to select the method they prefer.

  3. Examine the overall health of periodontium clinically and radiographically to ensure the client is able to receive treatment and ideal results can be achieved.

  4. Obtain impressions and clinical photographs required for use in treatment planning.

  5. Evaluate the dentition for areas of crowding and determine if additional space will need to be made through interproximal reduction techniques (can obtain up to 3mm through interproximal reduction).

  6. A prescription is sent to a lab, identifying the type of aligner required . This device is then fabricated on a “corrected” model, which is made to match the specifications provided by the dentist.

  7. Once the client returns for the insertion appointment, the client is able to place the aligner in the mouth, and the reduction of the interproximal surfaces can begin if necessary.

  8. The client should be educated on how to use and clean the appliance.

  9. After 2 - 3 weeks the client returns for evaluation of treatment progress and if necessary, to make adjustments to the appliance. This continues and treatment is modified as necessary to compensate for individual differences until the treatment is complete.
