OBJETIVO: relatar o tratamento de uma paciente com apinhamento severo decorrente de uma atresia maxilomandibular, tratada por meio da Distração Osteogênica da Sínfise Mandibular (DOSM). RESULTADOS: neste caso, observamos bom engrenamento dentário, diminuição do corredor bucal escuro, correção do apinhamento, boa forma de arcos e boa estética facial, num período de tempo bastante satisfatório, sem trazer dano ao tecido periodontal adjacente. CONCLUSÃO: pacientes com arcos atrésicos e apinhamento dentário podem ser beneficiados com a DOSM que, quando bem indicada, surge como uma nova forma de tratamento para casos limítrofes de apinhamento dentário, nos quais as alternativas convencionais oferecem limitações, tais como o achatamento do perfil facial, o aumento do corredor bucal e a instabilidade.

OBJECTIVE: This study assessed the anterior-posterior positioning of the upper and lower first molars, and the degree of rotation of the upper first molars in individuals with Class II, division 1, malocclusion. METHODS: Asymmetry I, an accurate device, was used to assess sixty sets of dental casts from 27 females and 33 males, aged between 12 and 21 years old, with bilateral Class II, division 1. The sagittal position of the molars was determined by positioning the casts onto the device, considering the midpalatal suture as a symmetry reference, and then measuring the distance between the mesial marginal ridge of the most distal molar and the mesial marginal ridge of its counterpart. With regard to the degree of rotation of the upper molar, the distance between landmarks on the mesial marginal ridge was measured. Chi-square test with a 5% significance level was used to verify the variation in molars position. Student's t test at 5% significance was used for statistical analysis. RESULTS: A great number of lower molars mesially positioned was registered, and the comparison between the right and left sides also demonstrated a higher number of mesially positioned molars on the right side of both arches. The average rotation of the molars was found to be 0.76 mm and 0.93 mm for the right and left sides, respectively. CONCLUSION: No statistically significant difference was detected between the mean values of molars mesialization regardless of the side and arch. Molars rotation, measured in millimeters, represented ¼ of Class II.

During the aging process, increase the postural asymmetries that can affect the control mechanism of balance leading to falls. To evaluate the static posture of elderly; measure the balance and correlate the results of the posture with balance. The study involved 28 elderly patients, 13 males and 15 females (71.8 ± 5.7 years). The volunteers were photographed, the images transferred to a computer for evaluation of static posture and calculating the projection of the center of gravity in the frontal and sagittal planes using the Postural Assessment Software. The balance was assessed by the Berg Balance Scale (BBS). Correlations were performed by Spearman test (p ≤ 0.05). Data were presented as mean ± standart deviation (SD). BBS scores = 50.5 ± 3.3; the sagittal plane (anterior asymmetry) = 45.5 ± 11.1%; frontal plane (right or left asymmetry) = 9.8 ± 7.9. We found a correlation between BBS and asymmetry of the sagittal plane (r = -0.46, p = 0.01) and between BBS and asymmetry of the frontal plane (r = -0.41, p = 0.03). The data suggest that the higher the previous projection (asymmetry of the sagittal plane) and lateral projection (asymmetry of the frontal plane), scores of the BBs will be lower, indicating an increase of unbalance in elderly.

Introduction: Hemiparesis is the most common sequels after Stroke. One of the side effects of the motor skills evident in hemiparesis is the tendency to remain in asymmetric posture, with lower distribution of weight on the side hemiparetic, which ends up leading to a deficit in balance. This set of changes can cause an asymmetrical type of gait, marked by difference between the lengths of the steps these individuals. Objective: The purpose of this study was to analyze the balance, the discharge of weight in the lower limbs and asymmetry of steps in hemiparetic individuals and sees if there is correlation between those variables. Method: A group of 12 hemiparetic individuals (55,33 ± 8,92 years), both sex, who suffered from strokes participated. All subjects performed the assessment of bilateral discharge of weight, the length of the steps and balance (Berg Balance Scale). The results for the difference in the discharge of weight of the lower limbs, asymmetry of the step and the performance on the test of balance were analyzed using the Sperman Correlation Coefficient with a significance level of 5% (p ≤ 0.05). Results: We found a significant correlation between balance and asymmetry of the steps (R = -0.72 and p = 0007), however, found no significant correlation between discharge of weight on each leg and the symmetry of the steps (R =- 0.07 and p = 0, 81) and between discharge of weight and balance (R =- 0.08 and p = 0.79) in these hemiparetic individuals. Conclusion: Can be conclude that hemiparetic individuals of these study show deficits in balance, difference in weight between the discharge of the lower limbs and asymmetry of step and correlation between the asymmetry of the step and balance.

Existe uma lacuna na literatura no que diz respeito chutes no futsal, ainda mais em relação as diferenças entre membros contralaterais. Portanto o objetivo do estudo foi analisar e comparar os parâmetros espaço-temporais da corrida de aproximação e de desempenho (precisão e velocidade da bola) de chutes realizados com o membro dominante e membro não dominante para diferentes tipos de chutes no futsal, separadamente para a bola em posição estacionária e para a bola em deslocamento. Participaram do estudo cinco jogadores destros e cinco jogadores sinistros de futsal da equipe adulta da UNESP – Campus Rio Claro. Os participantes realizaram 10 chutes com a bola parada e 10 chutes com a bola em deslocamento, sendo que em cada situação 5 chutes foram realizados com o membro dominante (MD) e os outros 5 chutes com o membro não dominante (MND). Para a bola parada os chutes foram realizados na marca do tiro livre (10 m distante do gol). Para bola em deslocamento foi utilizada uma rampa para padronizar a velocidade de chegada da bola. Os participantes foram instruídos a realizar o chute com o dorso do pé o mais forte que conseguir, tendo como objetivo acerta um alvo de 1m² posicionado no centro do gol. Os chutes foram filmados por seis câmeras digitais JVC® modelo GR9800u, ajustadas com freqüência de aquisição de 120 Hz, shutter a 1/250, white balance e o foco definido de forma manual. Foram fixados marcadores nas proeminências ósseas dos membros inferiores direito e esquerdo dos participantes. As variáveis dependentes foram: velocidade da corrida de aproximação; distância do pé de suporte para a bola; ângulo de aproximação para a bola; distância do participante para a bola; velocidade da bola; e comprimento e largura do passo durante a corrida de aproximação. As variáveis foram comparadas através de análise de variância (ANOVA) com medidas repetidas e com fator... (Resumo completo, clicar acesso eletrônico abaixo)

Two treatment options are available for adult patients with skeletal Class II malocclusion caused by mandibular deficiency: combined mandibular advancement surgery and orthodontic treatment or mandibular advancement appliance. This study aimed to analyze the effects of two therapeutic modalities of Class II malocclusion treatment with mandibular deficiency. Two distinct individuals with Class II malocclusion division 1 and mandibular deficiency were treated after growth spurt. The first individual used the Herbst appliance as a therapeutic option and the second individual was treated with bilateral sagittal osteotomy. The cephalometric, occlusion and face results were evaluated for both individuals. Correction of Class II malocclusion was observed on both Herbst and surgery patients resulting on a normal occlusal relationship with normal overjet and overbite. Therefore it was concluded that Herbst appliance can be used to treat borderline skeletal Class II in adult patients.

The aim of this study was to evaluate the stability of the conservative condylectomy technique and articular disc repositioning as the surgical treatment approach for management of mandibular condylar osteochondroma, with appropriate Orthognathic surgery. Fifteen patients (12 females and 3 males), average age of 32.3 years (range, 13 to 56 years), with unilateral active osteochondroma of the mandibular condyle were analyzed. All patients underwent conservative condylectomy, recontouring of the remaining condylar neck stump and articular disc repositioned and indicated orthognatic surgical procedures. Average post surgical follow-up was 19 months. Each patient's lateral cephalograms were traced at 3 intervals (presurgery, immediate post surgery and long-term follow-up). Immediate after surgery the oclusal plane angle decreased -2.8 ± 4.5o, the maxillomandibular complex rotated counter-clockwise with advancement at menton 5.3 ± 5.6 mm, pogonion 5.0 ± 5.1 mm, B point 3.4 ± 4.2 mm and A point 1.0 ± 1.5 mm. The long-term follow-up showed significant changes in overbite (-0.6 ± 0.5 mm) and SNGoMe (0,93° ± 1,53°). Horizontally and vertically small instabilities occurred in Me (-1.21 ± 1.94 mm) and PNS (-1.48 ± 1.67 mm) respectively. The treatment protocol studied produced counterclockwise rotation and maxillofacial mandibular advancement. The long-term follow-up showed solid dental and skeletal stability with horizontal instability of Me and PNS in the vertical direction.

This case report presents details of a new surgical technique for mandibular ridge sagittal osteotomy and expansion associated to immediate dental implants in atrophic ridges. The bone atrophies represents a challenge for the surgeons that intends to modify this situation. In the past, the only viable option was the onlay bone graft. However, the bone graft requests a second surgical site that certainly increases the postoperative morbidity, without mentioning the longer treatment time required. The sagittal osteotomy of the alveolar crest represents a faster option, because it eliminates the time requested for bone graft integration, providing rehabilitation of edentulous areas with thin alveolar crests that otherwise would need additi onal surgical procedures for a satisfactory result. The authors report a clinical case in which this technique was used with the installation of a Bicon dental implant in the same surgical time, showing all the steps for this single-tooth rehabilitation.

Purpose: Trying to provide more anatomical data to the oral and maxillofacial surgeons regarding to orthognathic surgery, specifically about sagittal split osteotomy, the authors accomplished an anatomical study in dry human jaws, measuring the thickness in four previously established points of the body and mandibular ramus, at the usual spots used for the internal fixation by screws. Material and Methods: The authors also use the data collected to evaluate if there are significant differences between the group I (human dry mandibles with teeth) and group II (edentulous human dry mandibles). Results: For the group I the authors found the following results: x1 = 14,48, x2 = 14,94, x3=12,82 and x4 = 9,41, being the x2 the thickest point, and the least thick the x4. However in the group II, the found medium values were: x1 = 13,38, x2 = 13,08, x3 = 11,63 and x4 = 12,18, being the thickest point in that group the x1 and the least thick x3. The coefficient of simple correlation between the variables (group I and II) revealed a value of 0,6194, being this difference no significant at the meaning level of 95%.
