Konklusionen i en artikel fra “Dental Tribune Nordic Edition” er, at ortodontiske behandling (re.: bøjle behandling) med Invisalign har signifikant lavere negativ indflydelse på patienternes tilstand end behandling med almindelige “togskinner” både mht tandkødets sundhed og alment befindende.
Det er jo noget vi har været klar over i mange år og har bl.a. noget at gøre med at de kræfter der udsættes på tænderne er meget mere velregulerede med Invisalign end med “togskinner”, så ud over det kosmetiske med at man ikke kan se bøjlen er det absolut en ekstra fordel at tænderne behandles mere skånsomt. Har du spørgsmål angående Invisalign må du endelig ringe/kigge ind, så vil vi besvare dem.

Clear aligners to be more beneficial than braces.

Mainz, Germany: In recent years, clear aligners have become a favorable treatment alternative in orthodontics to fixe ortodontic appliances (FOA). However, there are few studies about the effect of aligner treatment of oral hygiejne and gingivalcondition. A team of German researchers has now compared the oral Health status, orla hygiejne and treatment satisfaction of patients treated with FOA and the Invisalign alignersystem. They ound that Invisalign patients have better periodontal Health and grater satisfaction during orthodontic treatment. To date, the majority of patients, particulary during childhood and adolescence, are trated with FOA. However these appliances tend to compicate hygiene and Thus interfere with patient´s periodontal Health. Moreover, tratment with FOA is not very popular in the adult orthodontics for aestethic reasons. Therefor, other orthodontic techniques have been developed to improve aestethics and simplify oral hygiene procedures. An alternative to FOA is clear aligners, which are discret and have the advantage of being removable during oral higiene and eating og drinking. The use of clear aligners has increased greatly in the last decade, one prominent example being Invisalign, produced by Align Tecnology since 1999. However, only a limited number of studies have compared the effects of Invisalign and FOA on oralhygiene, the reseachers from the Johannes Gutenberg University og Mainz pointed out.

Their study included 100 patients WHO underwent orthodontic treatment, divided equaly between FOA and Invisalign for more then six months. The researchers performed clinical examinations before and after treatment to evaluate the patients´periodontal condition and anychanges: furthermore, adetailed questionaire assesed the patients´personal oral hygiene and diatary habits, as well as satisfaction with the treatment. All of the patients recieved the same oral hygiene instructions before and during orthodontic treatment. This included the use of toothbrush, dental floss and interdental brushes three times daily.

The data analyses showed no differensces between the two Groups regarding periodontal Health and oralhygiene prior to the orthodontic treatment. However, the researchers observed notable changes in periodontal condition in both Groups during orthodontic tratment. They found that gingival Health was significant better in patients with Invisalign , and the amount of dentalplaque was also less but not significantly different compared with FOA hygeine prior to the orthodontic tratment.However, the researchers observed notable changes in periodontal condition in both Groups during orthodontic tratment.They found that gingival Health was significant better in patients trated with Invisalign, and the amount of dental plawue was also less but no significant differnt compared with FOA patients.

The questionaire results showed greater satisfaction in patients trated with Invisalign. Only 6 per cent of the Invisalign patiens reported impirment of their general well-being during orthodontic tratment, compared with 36 per cent of the FOA patients. Other negative effects that also were significantly higher in FOA patients included gingival imitation (FOA : 56 per cent; Invisalign: 14 per cent), being kept from lughing for aestetics reasons (FOA: 26 per cent; Invisalign: 6 per cent), having to change eating habits during orthodontic teatmetn (FOA: 70 per cent; Invisalign: 50 per cent), and having to brush one´s teeth for longer and more often (FOA: 84 per cent; Invisalign: 52 per cent).

The reasearchers concluded that orthodontic treatment with Invisalign has significantly lower negative impacts on a patients´condition than tratment with FOA, both with regard to gingival Health and overall well-being.
