Problems can’t be fixed by Invisalign but can be corrected by orthodontic

Invisalign has become important for general dentistry. These clear plastic aligners are popular among adults and teens who don’t want traditional braces. They need to be worn for a minimum of 22 hours per day. The aligners can be removed while eating, drinking, brushing and flossing. They have to be replaced in every 2 weeks with a new set for better results.

Invisalign are very expensive as compared to traditional metal or clear braces. It is important to know that every patient is not appropriate for Invisalign treatment. It can treat various orthodontic issues such as overbite, crossbite, underbite, gapped teeth and crowding. Below are a few situations which cannot be fixed by Invisalign.

  • Shape

Many patients’ teeth are not ideal that can fit inside the aligner. They might have short, round, pegged teeth or with pointed tips. Due to this, the aligner will not get a good grip on teeth. In such a situation, the aligner is not appropriate for moving teeth into the desired position.

  • Position

A tooth might rotate to fit if a mouth is overcrowded. Invisalign will not be able to move them into the desired position if molars rotate too much. The rotation is more in case of canines, premolars and incisors.

In a crowded mouth, teeth either tilt forward or back to fit. Due to this, Invisalign will not be able to pull the tooth up into the appropriate place.

  • Large gaps

Nobody likes gaps between the teeth whether it’s between two or more. Every patient wants to get them closed. With Invisalign, only 6mm of space can be possibly closed among the top or lower teeth.

  • Intrusion or extrusion

To make the height of the teeth same, orthodontics can increase and lower the position of teeth in the jawbone. Braces forcefully move the teeth into the desired position whereas Invisalign provides limited movement in the front teeth and no movement in the back teeth.

  • Midline movements

Many patients’ front teeth do not match with their midline which is an imaginary line down the middle of the face. Invisalign treatment is successful in treating midline issues by 2mm to the left or right per teeth. For the large type of corrections, braces are the best choice.

  • Pre-dental work

Some kind of prior dental work may not allow patients from using Invisalign. The chance of getting Invisalign reduces with a dental bridge, porcelain veneers or crowns. These do not allow the use of attachments with the Invisalign as they can’t bond to the surface.

  • New dental work

If you have dental work such as crowns or porcelain veneers after Invisalign retainers, they may not fit properly or will not be effective into pushing the teeth at right place. Before proceeding, orthodontic will check the previous dental treatment to ensure whether Invisalign is suitable or not.

All the dental restoration work must be stopped once the aligners have been made and Invisalign treatment has been completed.

  • Periodontal problems

Gums should be healthy before Invisalign treatment. Though aligners move the bones still there are chances of tooth decay and loss if periodontal disease is not treated prior. Get it treated from a Periodontist before Invisalign treatment.

  • Do not eliminate the need for tooth extraction

Before getting Invisalign, teeth may require to be extracted if you have overcrowding issue. This will create extra space similar to metal or clear braces. Invisalign is not suitable when teeth have been extracted because the appliance cannot keep the teeth upright during space closure.

  • Use of visible attachments

This treatment is popular among patients because the aligners are virtually invisible. Some patients may have to use attachments with their Invisalign. The enamel colored attachment is slightly visible.

With improved technology and experienced orthodontists, limitations are reducing. Many complex cases can now be treated successfully with Invisalign. It cannot be denied Invisalign is meant for giving the patients appearance and dental hygiene back. You need to have a complete education about caring for teeth and aligners during treatment. There is an increased risk of tooth decay and damage if you do not follow the treatment guidelines. Therefore, Invisalign is a cost-effective but aesthetically-pleasing treatment which can meet the needs of many patients.
