Invisible orthodontics in adults Lingual technique – invisalign
- Since the advent of orthodontics, all our orthodontic treatments, particularly fixed treatments, were based on the vestibular surfaces of the teeth,
- But in view of the demands of patients who do not wish to suffer the aesthetic damage of metal appliances, particularly in adults, new techniques have appeared in contemporary orthodontics, such as the lingual technique and treatment using a splint known as aligners.
The lingual technique
- It appeared in the early 1980s jointly in the United States and Japan, in response to patient demands (aesthetic side despite the presence of ceramic brackets),
- This is the only technique that is completely invisible since the brackets are glued to the lingual surfaces.
- Technique that requires rigorous work both in the clinic and in the laboratory because the brackets are individualized
Procedure
- Photography and X-ray
- Footprints
- Set up done by the laboratory following the practitioner’s instructions
- Validation of the set up
- Production of an indirect bonding gutter by the laboratory
- Bracket bonding using the indirect technique
Benefits
- Lingual orthodontics only invisible technique
- Precision and ease of gluing of the boxes thanks to indirect gluing
- The initial set up allows you to achieve the expected results
- According to Wichman, less decalcification of enamel in lingual technique than in vestibular technique
- As these are individualized brackets, information is incorporated at the torque level
Disadvantages
- Difficulty with diction (speech)
- Longer adaptation time
- Higher periodontal risks
- Risk of tongue injury
- Risk of detachment of the boxes especially at the anterior level
- Risk of root resorption
- High cost and
- Technique not suitable for treatment of all orthodontic anomalies
Lingual technique

The incognito lingual
- It is derived from the lingual technique but the attachments are individualized and perfectly adapted to the patient’s dental anatomical particularities,
- The fasteners are made of gold (reduction of allergies)
- Very flat, reduced irritation, chewing and speech problems
- Computer-aided arch fabrication based on attachment positioning
The aligners

invisalign
- New concept of orthodontic treatment that requires a series of individual transparent aligners for each patient, it is a technique where the device is discreet and less visible
Process
- The Invisalign process only requires a 3D optical impression
- And from this impression a series of gutters are made thanks to the intervention of the computer according to the treatment plan initiated by the orthodontist and the treatment objectives,
- It sometimes happens that during treatment we modify the therapeutic approach and then the data is transmitted for the making of other gutters (or aligners) as we can increase the number of gutters when the objectives are not achieved.
Advantage
- Better aesthetics and ease of cleaning,
- No increased periodontal risk,
- Shorter adaptation time compared to other therapies ,
- Easy removal of aligners,
- Less pain compared to conventional treatment
Aligners
Conclusion
- Lingual technique and aligners now often replace treatment with conventional appliances in most classic cases, thus making it possible to correct malocclusions but also offering patients a certain comfort and aesthetic satisfaction during the treatment period.
The patient’s request for a lingual technique or aligners must be taken into account by the orthodontist who masters both techniques, and it is up to the latter to decide on the possibility of implementing one or the other technique depending on the case and the possibility of achieving the treatment objectives while explaining the limits of these two techniques which present a significantly higher cost compared to the conventional one.
