The Invisalign technique is an orthodontic procedure to correct misaligned teeth using a series of removable transparent plastic trays called aligners. Learn more about Invisalign here. Each aligner has a wearing period of 14 days. With each aligner, the strength and direction of the forces acting on the tooth changes little, so that progress towards the goal of treatment is made in many small individual steps. Depending on the severity of the malocclusion to be treated, 10 to 50 aligners are required. Splints should be worn at least 22 hours a day, except for food and intensive oral hygiene and special occasions. The treatment period lasts from 9 to 18 months.
The main advantage of therapeutics with aligners is not restricted oral hygiene and the fact that they are almost invisible. The Invisalign procedure represents an enrichment for the orthodontic treatment spectrum with respect to professional groups with special aesthetic and phonetic requirements. Moreover, studies show that initial wear is less comfortable for the patient compared to fixed equipment.
One disadvantage is that, in principle, splints do not have the same possibilities as fixed orthodontic techniques with respect to the force applied to the tooth. Therefore, if necessary, additional attachments (fasteners), such as buttons that are adhesive attached to the tooth with composite technology, should be used to move a tooth spatially, i.e., not just to tilt it by two. dimensional. Finally, the combination of fixed equipment is also possible, which means that the range of indications can be expanded almost indefinitely.
The range of possible applications varies from simple (10 to 20 aligners) to pronounced (20-50 aligners) tooth position corrections. The latter may be necessary, for example, after tooth extraction (tooth removal).
The main area of application is for the following correction needs, assuming stable neutral intercuspidation (multipoint contact between upper and lower teeth):
- Moderate compression of the anterior teeth.
- Moderate degree gap of anterior teeth
- Protrusion of the anterior teeth (the crowns of the teeth tilt towards the lip ).
- The return of the anterior teeth (the crowns of the teeth tilt towards the oral cavity ).
- Low degree of penetration (teeth recessed in jaw).
- Low degree of extrusion (teeth are elongated): here, the aforementioned attachments are also used
Only an optional use option is available for the following corrective requirements, unless additional orthodontic equipment is used:
- Cancellation of torsion (rotation around the longitudinal axis) of canines or premolars (anterior molar);
- Gap closure, for example, after systematic symmetrical extraction of the first premolars (removal of the first anterior molars);
- Tooth retains (remaining teeth in the bone beyond their natural time of eruption).
The Invisalign method
- Preparation of report on current malocclusion and orthodontist treatment planning.
- Impressions of the upper and lower jaw with an addition-cured silicon (impression material without shrinkage).
- Takes the bite to move the positional relationship between the upper and lower jaw .
- Scanning impressions
- Computer-aided 3D simulation of planned tooth position corrections.
- The company Invisalign Technology made the splint series based on the planning documents sent by the orthodontist.
- Entering the patient's first aligner, instructions for conduct.
- Regular progress checks
