FAQ

How do I get started with LM-Activator?

LM-Dental arranges training courses with experienced lecturers. The best way of getting started is to attend a training course. If you are interested in participating, please give your contact details here.

How is the right model chosen?

A thorough case-by-case analysis of the patient’s malocclusion and its severity as well as the patient’s motivation is needed. Evaluating the dentoalveolar, skeletal and functional characteristics of the patient is an essential part of selecting cases for LM-Activator treatment. A large assortment of models makes it possible to select the appropriate LM-Activator for the patient without need for individual modifications.

Please see some rules for model selection.

LM-OrthoSizer is a measure for aiding the selection of the appropriate size. It measures the distance across the upper incisors. In case of crowding or diastemas, consider a larger or smaller appliance.

More information on selecting the size with LM-OrtoSizer.

For what kind of malocclusion is treatment with LM-Activator suitable?

LM-Activator has proven to be effective in treatment of different malocclusions in different dental stages. A thorough case-by-case analysis of the patient’s malocclusion and its severity as well as the patient’s motivation is needed. Evaluating the dentoalveolar, skeletal and functional characteristics of the patient is an essential part of selecting cases for LM-Activator treatment. Typical cases include deep-bite, crowding and dentoalveolar anterior crossbite.

Please see the guidelines for case selection.

Do I need to change the LM-Activator during treatment?

The number of appliances depends on the type of the malocclusions and the duration of treatment. Sometimes one appliance is sufficient and sometimes a number of appliances are needed.
An example is to change from Short model to Long model when the second molars have erupted. Another example is that it may be necessary to change to a larger size when the maxillary and mandibular lateral incisors begin to erupt. In case of crowding or diastemas, consider selecting a larger or smaller appliance (1-2 sizes smaller or larger). Take the expansion of the dental arches during the mixed dentition into account as well.

What are the benefits of LM-Activator compared to other treatments?

With LM-Activator, alignment, leveling and anteroposterior correction can be done at the same time without separate phases. A large assortment of models makes it possible to select the appropriate LM-Activator for the patient without need for individual modifications. Treatment complexity for both the clinician and the patient can be reduced.

What are the benefits of intervening early?

  • By intervening early, the development of a malocclusion may be prevented. Research indicates that small malocclusions develop into more severe malocclusions. Straightening protruding front teeth reduces the risk that a tooth is damaged in an accident.
  • Speech or chewing problems caused by the occlusion may be avoided.
  • Self-esteem can be improved by correcting visible malocclusions.
  • Malocclusion may increase the risk of caries. By correcting the malocclusion without delay, the risk of caries can be reduced.
  • When treating early, more gentle orthodontic treatment like LM-Activator can be used instead of more complex treatment applying more force.

How to support co-operation?

With all removable appliances, patient co-operation is essential for successful treatment. The first month is crucial in adopting the habit to use the appliance, because creating a habit in general requires 3-4 weeks of regularity. To motivate the patient and his/her family, age appropriate material is available. It is important to make sure the patient and his/her family understands that irregular use may be equivalent with no treatment at all.

Sleeping with LM-Activator might require some practicing, so advise the patient to try sleeping with it a little longer every night. To practice keeping LM-Activator in the mouth during daytime makes it easier to keep it while sleeping. Many children get so used to sleeping with LM-Activator that they will find it difficult to sleep without it.

Frequently asked questions by patients

What is LM-Activator?

LM-Activator is a tooth aligner and activator made of soft silicone. It supports the healthy development of a child’s teeth and jaws. If a tooth is not developing in the right way, LM-Activator can gently guide it to the correct place and position. At the same time, LM-Activator supports the natural growth of the face for achieving a healthy relationship between upper and lower jaws.

Intervening already when a small problem or risk is detected may prevent it from developing into a bigger problem. LM-Activator provides soft guidance to teeth and jaws when needed and incorrect development can be avoided and corrected.

How is it used?

LM-Activator is used while sleeping. The teeth should be kept tightly in the appliance with lips closed. If treatment is started after eruption of the permanent upper centrals, two hours of day-wear is recommended in addition to night-wear. Day-wear is continued until the malocclusion is corrected.

How does it work?

If a tooth is not developing in the right way, LM-Activator can gently guide it to the correct place and position. LM-Activator moves the teeth and jaw a small step in the right direction every night. If it is not used, they will move back. Therefore a regular use is important.

When the teeth and jaw have found the right places, LM-Activator helps keeping them there.

If your tongue is lying on the floor of the mouth, LM-Activator helps the tongue find the roof of the mouth

LM-Activator also helps you to breathe through your nose.

Is it difficult to breathe with it?

The natural way to breath is to breathe through the nose with the mouth closed, except for when talking or during sports or physical exercise. It is easy to breathe with LM-Activator because it allows you to breathe freely through your nose. If allergy or flu is causing nose stuffiness that makes it difficult to breathe through your nose, the flu or allergy should be taken care of before starting to use LM-Activator.

Chronic mouth breathing can cause problems with oral hygiene, gingivitis and may possibly interfere with natural growth of the face and airways. LM-Activator makes it easier for mouth breathers to learn to breathe through the nose.

Is it difficult to sleep with?

Sleeping with LM-Activator might require some practicing in the beginning, because LM-Activator may fall out while sleeping before you get used to it. Keeping it in the mouth during daytime makes it easier to keep it in the mouth while sleeping. You will soon be used to sleeping with it. Many children get so used to sleeping with it that they will find it difficult to sleep without it.

Will the treatment be painful?

Using LM-Activator feels comfortable. During the first days there might be a feeling of tension, which is normal and means that LM-Activator is working and the soft silicone is applying force on the teeth. This will go away and you will soon be used to your LM-Activator.

What is the best age for the treatment?

LM-Activator can be used at different ages. Your dentist will evaluate the best time. Some children benefit from treatment as early as at the age five or six years. Even adults can use LM-Activator to treat milder malocclusions.

When the first milk tooth in the upper jaw falls out, the opportunities are wide for guiding the development of both teeth and jaws because the roots of the permanent teeth are not yet fully developed. When the roots are still growing, it may be easier on the teeth to guide them into the correct position and place.

Is LM-Activator suitable for adults?

Also adults have been treated successfully with LM-Activator but the possibilities are more limited than in childhood.

What is the benefit of LM-Activator compared to other treatments?

The smooth and flexible silicone and anatomical shape with round edges makes LM-Activator feel comfortable. Silicone is soft by nature so no softeners are needed and LM-Activator is additive free. No coloring or fragrance agents, phthalates or phthalate substitutes, bisphenols or latex.

LM-Activator is easy to clean and it can be disinfected in boiling water when needed (e.g. because of a flu).

LM-Activator is removable, which offers many benefits compared to e.g. fixed metal braces:

  • You can eat any food normally.
  • You can brush your teeth normally and the LM-Activator is also easy to clean.
  • You can exercise and do any sports.
  • LM-Activator is easy to use and no metal wire adjustment is needed. You save time and bother.

Where can I get this treatment?

Ask your dentist about the option of treatment with LM-Activator. Your dentist can evaluate your situation and tell you more about the options or refer you to a colleague.

Can there be any harmful side effects of the treatment?

The smooth and flexible silicone and anatomical shape with round edges makes LM-Activator feel comfortable. When LM-Activator is used according to the instructions and under the supervision of a dentist with special training and expertise in orthodontics, there is no need for concern.

Silicone is soft by nature so no softeners are needed and LM-Activator is additive free. It is fully biocompatible and there are no coloring or fragrance agents, phthalates or phthalate substitutes, bisphenols or latex.

How can I follow the progress of the treatment myself?

It is good to take photos at the start of the treatment and with regular intervals, e.g. once a month. When comparing the photos you can see the progress that you have made.

How can LM-Activator be cleaned?

Rinse LM-Activator daily before and after use. It can be cleaned by using a toothbrush. Toothpaste may cause scratches and shouldn’t be used. LM-Activator can be disinfected in boiling water for at least 1 minute. The box can be washed in a dishwasher. Inspect your LM-Activator regularly. If it is worn or damaged, do not use it and contact your dentist.

How do I store LM-Activator?

Always keep your LM-Activator in the same place to make it easier to remember to use it. Keep it in its own box.

Keep your LM-Activator in a place where pets can’t reach it because they may think it’s a chew toy. Dogs have a very good sense of smell and can find your LM-Activator because it has your scent.
