What are Smile Align active clear aligners?

Clear orthodontic aligners have been available since the mid 1990's. Most of these systems have been manufactured abroad making the cost, to a great extent, prohibitive in the South African context and excluding a vast number of potential candidates as a result.

The development of digital dentistry has enabled the design and manufacture of a multitude of dental devices which are more accurate and predictable in their outcomes due to high definition CAD/CAM software and manufacturing processes.

Not least of these are the digitally designed orthodontic aligner systems. A process which was formerly designed and manufactured by a laborious manual process is now far easier to achieve and clinically more acceptable due to strict orthodontic principles encapsulated within the CAD software.

While you as the prescribing clinician have the freedom to decide on the remedial approach you also have the advantage of a design system which can offer solutions where uncertainty exists. In these situations the prescription proposed by the dental designing technologist in conjunction with the orthodontic CAD system is available for your review and confirmation prior to any manufacturing taking place.

The manufacturing process consists of :

  • Establishing how many models are required to achieve the desired result using CAD software
  • Printing these models on a 3D printer using dental specific material.
  • Preparation of the models.
  • The pressure forming of the aligners out of ₠ certified bio-compatible polypropylene disks.
  • Preparing the disks. (cleaning, cutting, polishing)
  • Checking fit and personalised case specific aspects.
  • Packaging.

 

Cases that can be treated with clear aligners:

Aligner systems treat simple, mild and moderate cases. These cases represent in excess of 50% of orthodontic problems or aesthetic demands by patients.

Typical applications:

  • Crowded teeth
  • Cross bites
  • Spaced teeth
  • Deep bites
  • Protrusions

 

What results can you expect?

In principle it is possible to shift a tooth up to 0.5mm with one aligner.

Digital diagnosis will give a clear indication of how many aligners are required to achieve the desired goal.

Smile Align does not prescribe more than five aligners at a time. It is necessary for the patient to be re-assessed after the first course of treatment and new impressions must be taken for re-diagnosis and confirmation of progress.

 

How does the process work?

Please see the flow chart included for the basic overall concept.

The prospective patient should be examined and a diagnosis completed. Should you be uncertain about the suitability of the case submit an impression, plaster model, or intra oral scan for assessment and digital interpretation. Our design centre will return a report indicating suitability and a recommended case plan or will suggest that the case be referred to a specialist.

Should the case be suitable we require a prescription form and an impression, plaster model or intra-oral scan.

 

Approval:

Our design centre will assess the case and return a case report to you detailing the movement required by each tooth and consequently the number of aligners required and expected duration of the treatment. Confirmation of the case report will be deemed to be approval to move to the production phase.

Should you have any recommendations please make them in a writing on the case report form for implementation in the case design.

Once we have approval from your clinic we will proceed with manufacture.

The aligner set will be personalised, packaged and sent to your clinic for the patients next appointment.

 

 

You and your patient:

You are required to inform the patient of how the process works and the necessity for him/her to comply with a stringent oral hygiene routine and to follow the patient guide to the letter.

 

It cannot be over emphasised that the success of the process is determined by the length of time that the aligners are worn whilst paying more than normal attention to oral hygiene matters.

 

Educate the patient in the following:

How to identify the correct aligner, number sequence and how to insert and remove the aligner.

 

 

 

 

 

 

 

How to maintain the aligner: 

Clean after removing with water and toothpaste and a soft tooth brush.

No chemical cleaners, denture chemicals or abrasive liquids.

Flush well with water before re-inserting.

No warm/hot water.

Avoid foods which contain sugar and carbohydrates as they provide sustenance for bacteria which will thrive in the close confines of a dark moist aligner protected environment.

The aligners must be worn for at least 20-22 hours per day.

They must be worn 7 days per week.

They should be removed for eating and cleaning only.

Keep all of your aligners. If a problem arises with an aligner it is possible to go back to the previous one to avoid losing progress to date.

If you break or lose an aligner, replace it with the previous one. Return the damaged/lost aligner model to your Dentist as soon as possible. A replacement aligner will be provided. Do not go to a higher aligner unless in the last few days of the prescribed lost/broken aligner.

If an aligner is not worn for a day your teeth could lose all of the rotation that you have achieved and you will have to start again!

Do not skip aligners in the hope of speeding up the process. This could cause damage to the periodontic ligaments and loosen the tooth irreparably.

The patient may experience some physical discomfort during the first day or so of applying the first aligner. Prescribe or recommend a mild pain killer in this instance.

It is recommended that the patient schedule an appointment with you towards the end of the period of the second aligner, to assess progress and or problems.

 

Retainer:

As with most orthodontic procedures your patient will be required to wear a retainer after the treatment is complete. This will only have to be worn at night.

When the aligner treatment is completed it will be necessary to take a final impression and have a stronger - long term retainer manufactured. This will be done on the same principles as the aligners but will be a thicker material which should last for at least a year.

 

Software guidance:

What information can the design software provide me with?

A collision report, highlighting areas where interproximal or occlusal collisions will take place. This will provide a guide to where IPR should be implemented.

A degree of rotation report, showing how much rotation is needed to achieve the end goal.

 

Attachments:

Attachments may be required to achieve our goal.

They will be recommended by the dental designing technologist on a case-to-case basis and only applied where necessary.

Where are attachments generally required?

On intrusion, extrusion, premolar and canine cases.

The splint required for locating the attachments will be included in the patients aligner box. It too will be located on a model.

The attachment locators must be filled with UV curable acrylic, preferably white in colour and placed in the patients mouth. Make sure the aligner is properly seated and proceed to the curing phase. Once dry, remove the splint and inspect the quality of the attachment.

 

What do we need from you?

A high quality single impression (due to long shipping distances a reliable impression material like Impregum should be used and should be wrapped in wet tissue and shipped in a plastic bag to prevent shrinkage.), intra-oral scan or dental model of the affected arch if issues of opposing occlusal collision are not expected. (Accuracy is of utmost importance)

If in any doubt please send upper and lower impressions, intra-oral scans or dental models.

A completed prescription form with as much detail as possible.

 

What do we provide you with?

Marketing material in the form of patient information brochures and a stand for display in your waiting room/surgery.

Established Smile Align users will be provided with a marketing banner for improved customer awareness.

Hard copy or digital prescription forms to ensure accurate information transfer between your clinic and our production centre.

A video of the planning process from current situation to the expected result for your own confirmation and if required for the enlightenment of your patient.

Advertising on a variety of media platforms, printed as well as digital media.

A visit reference/evaluation card for your patient file.

 

What will your patient receive in the aligner set?

1) A box to keep new and used retainers.

2) An instruction/user's manual.

3) A set of aligners mounted on their respective models.

4) An abbreviated instruction pamphlet for quick reference.

5) An aligner holder for storing the current aligner when not in use.

6) If required an attachment model with its respective splint.

7) A visit reference/evaluation card for the patients file.
