“…The closing loop bends or elastic ligatures could deviate the midline or compromise canine relationship. 8,30 Fiorentino and Melsen 6 agreed that space closure in the posterior region of the arch is a difficult procedure, especially in Class II malocclusions. Thus, Bishara, Burkey and Kharouf 1 suggest the use of unilateral Class II or Class III elastics, associated with oblique anterior elastics to produce asymmetrical forces.…”

“…1 Stripping, single incisor extraction and asymmetric extraction of permanent teeth followed by asymmetrical mechanics would be good options for treating qualitative asymmetries. 1,2,6,8,16,30 Garn, Lewis and Kerewsky 7 observed that asymmetries in tooth size generally did not involve an entire side of the arch. Teeth of the same morphological class tend to have the same asymmetry.…”

“…14 Other authors state that asymmetric extractions (first premolar on one side and second premolar on the other) could help to correct midline deviations, anterior crowding and reduce the protrusion of the lower incisors in Class II subdivision malocclusions. 25,30 However, Gianelly et al 8 reported that the extraction of four first premolars would have the advantage of using an easier mechanical anchorage control, and to preserve the contact point between the second premolar and first molar (more anatomically correct and preferable than the contact of the first premolar with the first molar).…”

“…3,18 Therefore, many authors have suggested that asymmetric extractions would be necessary and important to correct midline deviation, favoring unilateral movement of the posterior teeth, reduce treatment time and tooth movement, facilitate orthodontic mechanics and obtain more stable and functional results. 6,8,15,18,23,30 This study aims to conduct a literature review about asymmetric extractions, emphasizing the importance of this procedure for orthodontics.…”

INTRODUCTION: Extraction decisions are extremely important in during treatment planning. In addition to the extraction decision orthodontists have to choose what tooth should be extracted for the best solution of the problem and the esthetic/functional benefit of the patient. OBJECTIVE: This article aims at reviewing the literature relating the advantages, disadvantages and clinical implications of asymmetric extractions to orthodontics. METHODS: Keywords were selected in English and Portuguese and the EndNote 9 program was used for data base search in PubMed, Web of Science (WSc) and LILACS. The selected articles were case reports, original articles and prospective or retrospective case-control studies concerning asymmetrical extractions of permanent teeth for the treatment of malocclusions. CONCLUSION: According to the literature reviewed asymmetric extractions can make some specific treatment mechanics easier. Cases finished with first permanent molars in Class II or III relationship in one or both sides seem not to cause esthetic or functional problems. However, diagnosis knowledge and mechanics control are essential for treatment success

Premaxillary distraction osteogenesis is a new method used to correct mild mid-face deficiency. In the presented case asymmetric application of this technique was used. A patient with upper midline shifting 3mm to the left side, Class I molar relationship, and slight anterior cross bite was referred to our clinic for orthodontic treatment. Retrusion of the upper incisors and midline shifting created a space deficiency at the left side of the maxillary arch and the left canine was positioned at vestibule, over the lateral incisor and first premolar teeth. Premaxillary segment was distracted asymmetrically by a tooth-born metal casting distractor designed in our clinic. At the end of treatment midline shift, anterior cross bite, and concave profile were corrected. Additionally, the required space for the alignment of the left canine was gained by the increase of the maxillary arch perimeter. ÖZET Orta hat sapmasının asimetrik premaksiller distraksiyon ile tedavisi: olgu sunumuPremaksiller distraksiyon, hafif dereceli orta yüz yetmezliğini düzeltmek için kullanılan yeni bir yöntemdir. Sunulan olguda, bu tekniğin asimetrik uygulaması kullanılmıştır. Üst orta hattı 3mm sola doğru kaymış, Sınıf I molar ilişkisi ve hafif ön çapraz kapanışı olan bir hasta ortodontik tedavi için kliniğimize başvurmuştur. Üst kesicilerin retrüzyonu ve orta hat sapması maksiller arkın sol tarafında yer yetmezliği yaratmış ve sol kanin diş vestibulde; yan kesici ve birinci küçük azı dişlerinin üzerinde konumlanmıştır. Kliniğimizde tasarlanan diş destekli metal döküm bir distraktör ile premaksiller segment asimetrik olarak distrakte edilmiştir. Tedavinin sonunda orta hat sapması, ön çapraz kapanış ve konkav profil düzeltilmiştir. Ayrıca, maksiller ark perimetresinin artması ile sol kanin dişin seviyelenmesi için gerekli olan yer kazanılmıştır.
