OBJECTIVE: To assess whether palatal mini-implants are effective as direct anchorage for distal movement of the upper molars. METHODS: It was used an acrylic model of the upper dental arch. After making a groove in the region corresponding to dental alveolus, acrylic teeth were fixed in groove with #7 wax, with the roots being previously immersed in adhesive wax. The orthodontic appliance was placed according to the Edgewise technique and then a mini-implant (SIN, São Paulo, Brazil) was inserted at the site corresponding to the palatal raphe. A 0.019 x 0.025-in stainless steel archwire was made and attached to the upper arch with elastics. A transpalatal arch bar (0.019 x 0.025in) was mounted and two hooks were soldered to it in order to retain chain elastics (Unitek, Brazil) to be connected to the mini-implant under a force of 1.5 N on each side. The maxillary model was immersed in water 40 times and photographed after each immersion, for observation of dental movements. Analysis of variance (ANOVA) and Tukey's test were employed for analyzing the obtained data. RESULTS: Molars displaced distally 3.1 mm, in average, with distal inclination ranging from 3 to 5 mm. CONCLUSIONS: Molar movements occurred due to distal inclination, with a slight rotation and no extrusive effect.

Pencabutan dini pada gigi desidui seringkali menyebabkan perpendekan lengkung sehingga ruang yang dibutuhkan untuk erupsi gigi permanen kurang. Kaninus ektopik, impaksi premolar dan asimetri rahang adalah kasus yang sering terjadi akibat kurangnya ruang untuk erupsi gigi. Pasien perempuan usia 20 tahun, mengeluhkan gigi gingsul dan tidak rapi. Pemeriksaan objektif menunjukkan crowding rahang atas dan rahang bawah, kaninus maksila kanan atas ektopik, premolar mandibula kanan impaksi, disertai pergeseran midline. Maloklusi Angle kelas I dengan hubungan skeletal kelas I, overbite 1 mm, overjet  1,3 mm, crowding mandibula dan maksila, ektopik kaninus unilateral, impaksi premolar unilateral, asimetri rahang dan pergeseran midline. Pencabutan dilakukan pada 2 gigi premolar pertama rahang atas dan 2 gigi molar pertama rahang bawah yang mengalami nekrosis. Perawatan menggunakan alat cekat teknik Edgewise dengan multiloop. L loop digunakan untuk ekstrusi gigi kaninus ektopik dan menarik impaksi premolar. Asimetri rahang dikoreksi dengan ekspansi lengkung gigi menggunakan mainarchwire. Setelah 7 bulan perawatan, gigi kaninus yang ektopik, impaksi premolar dan crowding terkoreksi. Overjet dan overbite menjadi 2,5 mm. Perawatan masih berlangsung hingga saat ini. Penggunaan multiloop pada teknik Edgewise efektif untuk mengoreksi crowding gigi dan L loop efektif untuk mengekstrusi gigi kaninus ektopik dan impaksi premolar. ABSTRACT: Management of Impacted Premolar, Ectopic Canine and Jaw Asymmetry Case Using Edgewise Technique. The premature loss of primary teeth may reduce the arch length required for permanent teeth eruption. Ectopic canine, premolar impaction and jaw asymmetry are often encountered due to the lack of space for permanent teeth eruption. A twenty-year-old female patient complained an ectopic canine and crowding of upper and lower teeth. The objective examination found maxilla and mandibula crowding, ectopic right maxilla canine, mandibular premolar impaction, and midline shift of maxilla and mandibula. Angle class I malocclusion, overbite 1 mm, overjet 1.3 mm, maxilla and mandibula crowding, unilateral ectopic canine, unilateral premolar impaction, jaw asymmetry and midline shift occurred. Extraction of 2 maxillary first premolars and 2 necrose mandibular first molars was conducted followed by a treatment using fixed orthodontic appliance Edgewise technique with multiloop. The ectopic canine and premolar impaction were extruded using L loop. Jaw asymmetry was corrected by expanding the dental arch using the expanded main archwire. Ectopic canine, premolar impaction, maxilla and mandibula crowding were corrected after 7 months of treatment. The overjet and overbite reached 2.5 mm. The treatment is still ongoing. The multiloop edgewise archwire technique is found effective to overcome dental crowding, and L loop is effective to extrude the ectopic canine and premolar impaction.

Impacted and transposed teeth cause serious difficulties in tooth eruption and movement as well as esthetic and functional outcomes. Proper treatment planning including good biomechanical control is essential in order to avoid side effects during traction and aligning of the impacted and/or transposed teeth. The purpose of the present study was to present a successfully treated female patient having transposed and impacted lower canines by means of a modified lingual arch and fixed orthodontic appliance. A female patient aged 13 years and 9 months presented to the orthodontic department with a chief compliant of bilateral spacing and missing teeth in mandibular dentition. After leveling and creating sufficient space in the mandibular arch for the canines, a modified lingual arch was cemented to the mandibular first molars. The lingual arch had two hooks extending to the distobuccal areas of the canine spaces. Elastic chains were applied between the hooks on the lingual arch and the ligatures tied to the attachments on the canine crowns. The light forces generated by elastic materials caused impacted canines to erupt and tend towards their own spaces in the dental arch. As a result, impacted and transposed lower canines were properly positioned in their spaces, and the treatment results were stable during the retention period.

The correction of rotated malpositioned tooth/teeth into the dental arch alignment in the mixed-dentition is often a challenging task for paediatric dentists. Failure in addressing this issue can bring about detrimental effect to the developing dentition and increases the probability of a complex orthodontic treatment in later years. Factors such as severity of the malpositioned teeth, patient’s treatment compliance, limitation in specific functions of the selected appliance, availability of bone and space may dictate the success of the treatment. The combined use of a simple sectional orthodontic wire appliance and a 2×4 orthodontic appliance has been shown to produce a positive effect. The appliances resulted in derotation of the rotated malpositioned teeth and bringing them into arch alignment in two cases. This treatment option had eliminated the detrimental effects to the developing dentition and helped patients to enhance their smile and dental aesthetics.

Introduction: The number of adult patients looking for orthodontic treatment has markedly increased in recent years. However, fake orthodontic appliance use, performed without minimum expertise or knowledge of the damage that it may cause to oral health, became very common in Brazil. Objective: To report the case of a male patient, 42 years old, who used an orthodontic appliance of uncertain origin. The patient had poor oral hygiene and grade III mobility in several units, and was referred to perform multiple extractions, with subsequent rehabilitation. Discussion: Orthodontic appliance used by orthodontists are strictly supervised by ANVISA. They are manufactured from biocompatible materials and their wires have specifically calibrated forces and appropriate formats to the dental arch, in order to move the teeth. Pirate accessories, without invoice and manufacturing origin, are usually found with street salesman. Materials used to make these devices, such as elastic bands, rubbers and dental yarns, are sold on the streets or in social networks. Often, application includes broom wires and superglue, in addition to twisted wires and elastic bands. These materials do not have any type of control and may cause poisoning, severe allergies and periodontal or dental changes. Final considerations: It is vital to dentists to be aware of this new fashion that has been adopted by young people, in order to make them aware of the risks they are subjected when adopting unnecessary use of dental appliance, without due supervision of specialized personnel.
