The author treated 3 class I malocclusion patients v,"ith the lingual appliance followed by the extraction of the 4 bicuspids. One of them was finished with the labial appliance at the final
stage. - .
The treatment results were acceptable and the patients had good tolerance to the -lingual appliance without complaints in these cases.
There were some problems in treatment on the lingual side both the patient and the practioner, but. I think we can overcome them with the development of the orthodontic materials, the treatment technics & the increased clinical experience. Of course, we cannot treat all the patients with the lingual braces, but patients are carefully selected, lingual braces will be a valuable orthodontic appliance.
In conclusion, the lingual braces have very good esthetic advantages, so the patients, especi;tty in adults, who hesitate or refuse the orthodontic treatment due to the esthetic problem of _he labial braces will get the motivation & the chance for the orthodontic treatment.
