The orthodontic minitubes system (FLOWJAC ® System, Bogotá, Colombia) is an innovating system that blend the selfligating philosophy techniques and a lowprofile appliance. The FLOWJAC® System works with low orthodontic forces, same as selfligation devices. The system uses heat-treated wires with better physical properties such as hysteresis when is compare with traditional wires. However, the FLOWJAC® technique doesn´t use a wire sequence to get a “working wire”, just a 0,014 Copper NiTi. The clinician in each appointment must modify the minitube location to the clinical desire teeth position. The present report blend FLOWJAC® devices in the upper arch and clear selfligation in the lower arch. The patient treated has mandibular bone resorption due a alloplastic chin augmentation. The root apex from first right premolar to the first left premolar seen to be near to the resorption area using Cone Beam Computer Tomography. That´s the reason why we use a pre-adjust devices in the lower arch, to avoid pulpar and periodontal counter effects. This case was finished with proper functional and aesthetics objectives; such as molar and canine class I, anterior open bite closure with 20% of overbite, coincidence of dental smile arch with lower lip, and without root and pulpar counter effects. The porpoise of this report is to present an orthodontic case with bone resorption on right premolar and incisors area of the mandible. The case was treated with selfligation orthodontics system; FLOWJAC® System in the upper arch and Empower Clear® (American Orthodontics Shebboyiang, USA) in the lower arch and could be done with a precise diagnosis and adequate treatment planning.

Skeletal Open Bite

Gigitan terbuka merupakan maloklusi yang bercirikan tidak terdapatnya tutup menutup gigi rahang atas dan bawah, dapat terjadi pada regio anterior maupun posterior dan dapat melibatkan dental maupun skeletal. Maloklusi ini memerlukan ketelitian dalam penentuan diagnosis dan perawatan untuk mendapatkan hasil perawatan yang baik dan kestabilan jangka panjang. Tujuan penulisan studi kasus ini adalah untuk menginformasikan manajemen pasien dengan gigitan terbuka tipe skeletal. Pasien pria berumur 19 tahun datang ke Klinik Ortodonsia FKG UGM dengan keluhan utama gigi depan yang tidak rata dan tidak dapat digunakan untuk menggigit. Pemeriksaan klinis menunjukkan pasien memiliki kebiasaan menelan dengan menjulurkan lidah. Pemeriksaan model studi menunjukkan maloklusi Angle kelas I dengan gigitan terbuka anterior dari regio premolar kedua kanan ke kiri sebesar 10,7 mm disertai malposisi gigi individual dan pergeseran garis tengah rahang bawah ke kiri. Pemeriksaan sefalometri menunjukkan relasi skeletal kelas II dengan retrusif bimaksila, rotasi mandibula searah jarum jam dan gigitan terbuka skeletal. Pasien menolak tindakan bedah ortognatik sehingga dilakukan perawatan ortodontik kamuflase. Perawatan diawali dengan latihan miofungsional untuk melatih cara penelanan yang benar dilanjutkan dengan perawatan ortodontik teknik straightwire dengan pencabutan empat gigi molar pertama. Penutupan gigitan terbuka menggunakan elastic box anterior. Hasil evaluasi menunjukkanpengurangan besar gigitan terbuka dari 10,7 mm menjadi 1,25 mm. Kesimpulannya elastic box anterior dapat digunakan untuk mengoreksi gigitan terbuka yang etiologinya melibatkan intrusi gigi anterior.  Skeletal Anteroposterior Open Bite Treatment with Straight Wire Technique. Open bite is a malocclusion with characteristic no overlapping between maxillar and mandibular teeth. This malocclusion may occur in anterior or posterior region and involved dental or skeletal. This malocclusion needed precise diagnosis and treatment to get a good treatment result and long term stability. The aim of this case report was to inform management of patient with skeletal open bite. A 19 years old male came to orthodontic clinic Faculty of Dentistry Gadjah Mada University with the chief complaint anterior crowding, and anterior teeth cannot be used to bite. Clinical finding showed patient had tongue thrusting habit. Study model analysis showed class I Angle malocclusion with 10.7 mm anterior open bite from right second premolar to left second premolar, with individual teeth malposition and mandibular midline shifting to the left. Cephalometric finding showed class II skeletal relationship with bimaxillar retrusive, clockwise mandibular rotation and skeletal open bite. This patient refused orthognatic surgery, so he received camouflage orthodontic treatment. This treatment was started with monofunctional exercise to correct the swallowing action then continued with straight wire orthodontic treatment with four first molar extractions. Anterior box elastic was used to close the bite. Evaluation result showed open bite was decreased from 10.7 mm to 1.25 mm. The conclusion was anterior box elastic could be used in open bite correction that involved anterior teeth intrusion as an etiology.

Introduction: Oral and dental (OD) disorders in children with Rubinstein-Taybi syndrome (RTS) are frequent but not well-known by dentists and pediatricians due to the syndrome being extremely rare. Objective: To describe the OD findings observed in a 5-year-old girl with RTS and to update the literature. Clinical case: The patient presented the following OD manifestations: prominent lower lip, narrow mouth opening, narrow and arched palate, history of angular cheilitis, micrognathia, poor lingual motility, plaque and tartar, bleeding from gingival areas due to poor dental prophylaxis, and malocclusion in the form of an anterior open bite. These OD manifestations are seen in more than 40-60% of patients with RTS. Conclusions: Professionals who treat children with RTS should become aware of the advisability of referring them to the pediatric dentist from 1 year of age and performing check-ups every 6 months. Dental management is often difficult so collaboration with anesthesiologists is recommended in order to carry out a safe and effective treatment.

Angle Class II malocclusion associated with anterior open bite in adult patients demands a carefully elaborated orthodontic planning, aiming at restoring not only harmonious dental and facial esthetics, but also a balanced masticatory function. Orthognathic surgery or permanent teeth extraction are often the choice of treatment, therefore, treatment decision is related to all dental, skeletal and functional aspects. The present report discusses orthodontic compensation carried out by means of upper premolar extraction performed to correct the Class II canine relationship and, consequently, the anterior open bite, accepting that the upper incisors be retroclined. This clinical case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as part of the requirements for obtaining the BBO Certification.

ABSTRACT Objective: This study aimed to compare the root length of maxillary and mandibular incisors between individuals with open bite versus matched individuals with adequate overbite. Methods: This comparative, matched and retrospective study included 48 cone beam computed tomographies (CBCTs) obtained at a university radiological center. Scans belonged to 24 individuals with open bite (overbite ≤ 0 mm) and 24 individuals with adequate overbite (controls). Both groups were matched by age, sex, malocclusion classification and skeletal characteristics (ANB and FMA angles). Root length of each maxillary and mandibular incisor was measured in millimeters (mm) in a sagittal section from a perpendicular line to the enamel cement junction until the root apex (384 length measurements were made). The means of root length in both groups were compared using t-tests. In addition, correlations between variables were evaluated with the Pearson correlation coefficient (α = 0.05). Results: In both groups, the root length of the upper central incisors was approximately 12 mm and the root length of the maxillary lateral incisors was approximately 13 mm (p˃ 0.05). Likewise, the root length of lower central incisors in both groups measured approximately 12 mm (p˃ 0.05). However, the mandibular lateral incisor roots of open bite patients were significantly longer than in the normal overbite patients (approximately 1 mm, p= 0.012 right side, p= 0.001 left side). Conclusions: Root length of maxillary incisors and central mandibular incisor is similar in individuals with or without open bite, but the mandibular lateral incisor roots in open bite patients were significantly longer than in the normal overbite patients.

Background: The correction of severe anterior open bite is technically challenging, often requiring the use of complex orthodontic mechanics and/or orthognathic surgery and has a relatively high risk of relapse. A marked reverse curve of Spee in the lower arch presents additional challenges when correcting a severe anterior open bite. Methods and Materials: A 22.2-year-old Caucasian man presented with concerns relating to poor anterior occlusion associated with a 1.3-cm anterior open bite. There was an accentuated reverse curve of Spee to the lower arch, an increased maxillary-mandibular plane angle and increased lower face height. Multidisciplinary treatment involving the use of segmental anterior mandibular distraction to level the curve of Spee before undertaking a Le Fort I posterior maxillary impaction is described in this case report. Results: Long-term post-treatment records showed stable anterior open bite correction. Conclusions: This case report illustrates the successful use of segmental anterior mandibular vertical distraction followed by conventional Le Fort I posterior impaction surgery to correct a severe anterior open bite associated with an accentuated reverse curve of Spee and high maxillary-mandibular plane angle.

The head and face are relatively common sites of gunshot injury, and the temporomandibular joint is often affected. These wounds usually produce major deformity and functional impairment, particularly when the temporomandibular joint is affected or when structures such as the facial nerve are damaged. Complications may include mandibular displacement at maximum mouth opening and in protrusion, limited mouth opening, limited lateral movement of the jaw, anterior open bite, and, more rarely, temporomandibular ankylosis. Projectiles that strike the mandible usually cause comminuted fractures; maxillary wounds, in turn, are most commonly perforating. The present report describes a case of gunshot injury in which the projectile lodged within the mandibular fossa but did not cause any fractures. Oral and maxillofacial trauma surgeons must be aware of the different types of gunshot injury, as they produce distinct patterns of tissue destruction due to projectile trajectory and release of kinetic energy into surrounding tissue.

ABSTRACT The aim of this case report was to present the combined orthodontic and surgical treatment of a patient with Apert syndrome in an adult stage. A 15 years old male patient with Apert syndrome was concerned about the appearance of his face and malocclusion. His profile was concave with a retruded maxilla and prominent lower lip. He had an Angle class I molar relationship with a 9.5 mm anterior open bite. The amount of crowding was 20.4 mm in the maxilla and 6 mm in the mandible. Cephalometric analysis revealed a skeletal Class III relationship due to maxillary hypoplasia with a dolichofacial growth pattern. Orthodontic treatment and orthognathic surgery were planned for the patient. After 45 months of presurgical orthodontics, the patient underwent two surgeries sequentially. The first surgery was performed to advance the maxilla and the second surgery was performed to correct the mandibular rotation and increase the overbite at the time of removing halo device. The amount of maxillary advencement was 8 mm. Mandibula was moved 1.5 mm anteriorly and rotated 1° to 1.5° (SNB and facial depth) in a counterclockwise direction. After a relatively long treatment, an esthetically pleasing and functional occlusion and correction of the skeletal problem was achieved in this adult case.

ABSTRACT Macrodontia is a rare dental anomaly which consists on the presence of any tooth or teeth larger than the average. In the present report the case of a child with an uncommon true isolated macrodontia of a maxillary central incisor is presented. The maxillary left central incisor was considered a macrodontic tooth since its mesiodistal crown dimension was 12.41 mm while the mesiodistal crown dimension of the maxillary right central incisor was 10.06 mm. The radiographic examination confirmed an enlarged maxillary left central incisor and a normal developing dentition. The patient did not report esthetic complaints, however, due the presence of anterior open bite and crowding, he was referred to orthodontic clinic. Thus, it must be point out the importance of the radiographic diagnosis to support the clinical findings, helping to plan and provide better treatment for the patient.

Tongue Thrust

Active digit-sucking results in 1) reduced vertical growth of the frontal parts of alveolar process which creates an anterior open bite; 2) proclination of the upper incisors as a result of the horizontal force crested by the digit; 3) anterior displacement of the maxilla for the same reason; 4) anterior rotation of the maxilla, resulting in an increased prevalence of posterior crossbite in the deciduous dentition; and 6) proclination or retroclination of the lower incisors which seems to be due to the strength of the tightness of the lower lip and tongue activity during sucking. When the sucking habit stops, the anterior open bite will correct itself spontaneously, due to increased growth of the alveolar processes, provided that the patient is still growing. If the lip activity and the lip/teeth relationship is normal, the upper incisors will upright themselves, and sometimes, due to the anterior displacement of maxilla, become somewhat retroclined. The skeletal effect of the sucking habit will remain. Improper use oi a pacifier can create quite disastrous effects on the occlusion, if, for instance, the child has the shield inside the lower lip or is biting into the shield. Otherwise, the effect of the pacifier is limited to the vertical and the transversal plane. The anterior openbite is normally more obvious and visible earlier in pacifier-suckers than in digit-suckers. As in digit-suckers, the open bite is associated with tongue thrust during swallowing. Also in pacifier-suckers, the open bite will correct itself spontaneously when the habit stops despite the tongue-thrust. Sucking a pacifier is more clearly related to a posterior crossbite in the deciduous dentition than is digit-sucking. When the pacifier is in the child’s mouth, the teat occupies the upper part of the anterior and middle part of the mouth thus forcing the tongue to a lower position. In the upper jaw, the teeth in the canine area lack palatal support from the tongue during the sucking activity of the cheeks. This reduces the arch width and increases the risk of a transversal malrelation between the upper and lower arches. The low tongue position widens the lower jaw in the same area thus enhancing the probability of the development of a posterior cross-bite.
