[Treatment of severe malpositions and impactions of the upper frontal teeth by fixed orthodontic techniques].
The upper frontal region is the site of various abnormalities of the teeth: in number, size, form and position. Crowding of the upper frontal teeth is one of the most common type of malocclusions. The purpose of this report is to describe and illustrate treatment of 3 cases with predominant abnormalities of the upper frontal teeth performed by fixed orthodontic techniques. The first case had Class II division 2 malocclusion associated with an impacted upper right central incisor, as well as transposition of the upper right lateral incisor and canine (non-extraction case). The second patient presented Class I malocclusion with severe crowding of the upper frontal teeth and an ectopic position of the upper right canine (extraction case). The third patient was with Class II division 2 malocclusion associated with a multiple impaction of the teeth. The following teeth were impacted: upper canines, upper left second premolar and lower second premolars (extraction case). The first case was treated by Straight Wire Arch combined with a headgear. The second patient was treated by Edgewise technique combined with a palatal arch. A combination of Edgewise technique and headgear was used in the treatment of the third case. The results obtained were functionally and aesthetically quite satisfactory.
