Materiais e Métodos: Dois modelos de osteotomia foram feitos em hemimandíbulas de poliuretano e divididos em dois grupos, ambos com 20 amostras: Grupo I - osteotomia angular e grupo II - osteotomia linear. Depois de um avanço de 5 mm do segmento distal, os segmentos ósseos foram fixados com diferentes sistemas de placa/parafuso de 2,0 mm, estabelecendo os sub-grupos: (A), uma placa reta convencional de 4 furos, (B), uma placa reta convencional de 4 furos associado a um parafuso bicortical, (C), uma placa reta com travamento de 4 furos, (D), uma placa reta com travamento de 4 furos associado a um parafuso bicortical. As amostras, foram então, submetidas ao carregamento linear a uma velocidade de 1 mm/min, até alcançar a carga de pico e falha do sistema. Resultados: Pelo teste de Tukey, o grupo de uma placa convencional associado a um parafuso bicortical mostrou ter uma carga superior a 3 mm de deslocamento (87,42 ± 4,86 N) estatisticamente significativa em comparação com o de uma placa convencional com parafusos monocorticais (p <0,01) e uma placa com travamento com parafusos mocorticais (p <0,01). O grupo de uma placa de travamento associado a um parafuso bicortical mostrou ter uma carga superior a 3 mm de deslocamento (72,47 ± 4,86 N) estatisticamente significativa em comparação com o de uma placa convencional com parafusos monocorticais (p = 0,02) e uma placa com travamento com parafusos mocorticais (p = 0,01). Não houve diferença estatisticamente significativa entre os grupos: uma placa convencional com parafusos monocorticais e uma placa com travamento com parafusos mocorticais (p = 0,65); uma placa convencional associado a um parafuso bicortical e uma placa com travamento associado a parafuso bicortical (p = 0,15). A osteotomia angular apresentou maior resistência mecânica em 3 mm de deslocamento do que a linear. No entanto, o único grupo que apresentou diferença estatisticamente significante foi o grupo A (p = 0,05). Conclusão: não houve diferença entre o sistema de fixação placa/parafuso convencional e com travamento; a adição de um parafuso bicortical na região retromolar promoveu uma melhor estabilização dos sistemas de fixação. A OSRM angular apresentou melhor resistência mecânica / Abstract: Purpose: Evaluate the mechanical resistance of four different osteosynthesis in two different design of sagittal split ramus osteotomy (SSRO) when submitted to vertical forces. Materials and Methods: Two osteotomy models were made on polyurethane hemimandibles. Group I - angled osteotomy and group II - linear osteotomy, both with 20 specimes. After 5-mm advancement of the distal segment, the bone segments were fixed by different osteosynthesis methods using 2.0-mm plate/screw systems, establishing sub-groups: A, one 4-hole conventional straight plate, B, one 4-hole conventional plate and one bicortical screw, C, one 4-hole locking straight plate, D, one 4-hole locking straight plate and 1 bicortical screw. The samples were then subjected to a linear load at a speed of 1 mm/min until reaching peak load and system failure. Results: A Tukey post-hoc test revealed that the group of one conventional plate with bicortical screws showed higher load (87.42 ±4.86 N ) with statistically significantly compared to one conventional plate with monocortical screws (p<0.01 ) and one locking plate with mocortical screws (p<0.01). The group of one locking plate with bicortical screws showed higher load (72.47 ±4.86 N ) with statistically significantly compared to one conventional plate with monocortical screws (p=0.02) and one locking plate with mocortical screws (p=0.01). There was not a statistically significant difference between groups: one conventional plate with monocortical screws and one locking plate with mocortical screws (p=0.65); one conventional plate with bicortical screws and one locking plate with bicortical screws (p=0.15). The osteotomy with angle showed higher mechanical resistance than linear. However, the only group that showed statistically significant differences was the group A (p=0.05). Conclusion: no statistical differences were detected between locking and standard system, the placement of 2.0-mm¿diameter bicortical screws in the retromolar region, promoted a better stabilization of bone segments. The angular SSRO offers the best mechanical resistance / Mestrado / Cirurgia e Traumatologia Buco-Maxilo-Faciais / Mestra em Clínica Odontológica

Title: Effect of Kinesio Taping on the functional condition of the musculoskeletal system The concept of the problem: The kinesiotaping method is currently very popular therapeutic method in sport as well as in physiotherapy. Although this method was primarily developed as therapeutic method, there is only a few studies, in which the kinesiotaping method is used on healthy individuals. Objective: The objective of this thesis is to evaluate the immediate effect of applied kinesio tape on changes in the range of motion of the thoracic spine in the sagittal plane on healthy individuals. Methods: The theoretical part deals with summary of the taping method as well as with anatomical and kinesiological aspects of flexion and extension of the thoracic spine. The practical part as an experiment (single blinded controlled trial) is dedicated to the application of kinesio and placebo tape, the way that both tapes were applied was specifically designed for the purpose of this thesis and for specifically selected individuals. For gathering the data and for the evaluation the changes in the range of motion, the index of thoracic spine mobility was used. Results: For experimental group - kinesio tape there were no statistically significant increase in the range of motion. Vice versa, according to the obtained...

Purpose: Anorectal malformations (ARM) are one of the most challenging congenital malformations in pediatric surgery. We aimed to assess the research activity on ARM over the last five decades. Methods: Data on original research publications were retrieved from the Web of Science Core Collection (1970–2020), and analyzed for countries, authors, scientific journals, and top-ten papers. Scientific quantity was assessed by the number of publications. Research quality was estimated from the number of citations, average citation rate per item (ACI), and h-index. Results: A total number of 1595 articles with 19,419 citations (ACI = 12.2; h-index = 54) were identified. The annual number of publications and citations significantly increased over time (p < 0.0001). The USA (n = 386; 24.2%), Japan (n = 153; 9.6%), and China (n = 137; 8.6%) were the most productive countries; and the USA (n = 7850; ACI = 20.3; h-index = 44), Japan (n = 1937; ACI = 12.6; h-index = 21), and the Netherlands (n = 1318; ACI = 17.3; h-index = 22) were the top cited countries. Articles were preferentially published in JPS (n = 391; 24.5%), PSI (n = 181; 11.3%), and EJPS (n = 56; 3.5%). Top-ten cited papers focused on classification (n = 1), surgical technique (n = 3), associated syndromes (n = 2), postoperative outcome (n = 3), and basic research (n = 1). Conclusion: This bibliometric study provides valuable insights into the global development of ARM research, and shows that clinical studies and international collaborations dominate in this field.

BAKGRUND Det är i nuläget ej klarlagt huruvida en mjukvävnadsprofil, utan hjälp av en profilröntgenbild, kan användas för att diagnostisera skelettala käkrelationer. Studiens syfte var att analysera möjligheten till att ställa en basal käkdiagnos och att diagnostisera incisivernas lutning utifrån en mjukvävnadsprofil och studiemodeller.METOD Studien har godkänts av Etiska nämnden vid Lunds Universitetet, Sverige. Nio patienter (sex pojkar och tre flickor, 12-16 år) som tidigare genomgått ortodontisk behandling på Tandvårdshögskolan i Malmö selekterades för studien. Patientfallen utgjorde underlag till ett protokoll bestående av extraorala fotografier, fotografier på gipsmodeller samt en panoramaröntgenbild men ingen profilröntgenbild. Protokollet sändes till 217 ortodontister i Sverige (166 protokoll besvarades). De uppmanades att ställa basala käkdiagnoser (sagittala och vertikala), bedöma incisivlutningen samt svara på frågor kring deras inställning till profilröntgenbilder. RESULTAT Sjuttio procent av ortodontisterna skattade att de tar en profilröntgenbild på de flesta av sina patienter. Bland de sagittala basala diagnoserna var det den postnormala diagnosen som visade sig vara den enklaste att identifiera och den prenormala diagnosen den svåraste. Av de vertikala basala diagnoserna var det enklast att identifiera en öppen relation medan den normala relationen var svårast. Överkäksincisivernas och underkäksincisivernas lutning kunde identifieras av 75 % respektive 47 % av ortodontisterna.KONKLUSIONER Studien visar att det i vissa fall går att ställa en ortodontisk diagnos och göra en terapiplanering utan en profilröntgenbild. Resultaten indikerar även att det inte är bettavvikelsen i sig som avgör huruvida en profilröntgenbild tas, utan att valet till större del baseras på ortodontistens egna preferenser.

Thesis (MEng) -- Stellenbosch University, 2014. / ENGLISH ABSTRACT: The Dorsiflexometer is a device designed and built for the assessment of a patient’s balance capabilities. The birth of the Dorsiflexometer is due to a serious need for physiological balance assessment equipment, capable of conducting dynamic tests in the clinical setting. This is accomplished by recording and analysing the patient’s response to sagittal plane perturbations. The Dorsiflexometer is operated from a computer software interface program. It uses the measurements from a single force plate to calculate four balance metrics’ characterising a patient’s ability to maintain balance. These balance metrics include the sway index, equilibrium score, postural stability index and radius parameter. A single and a double inverted pendulum model of the human body is derived to calculate a patient’s centre of mass movement in the sagittal plane with the measured force plate data and body parameters. Three experiments, involving 48 subjects, were conducted. The experimental tests proved the competency of the machine, the accuracy of both inverted pendulum models and the balance response of seafarers aboard an Antarctic research and supply vessel during rough sea conditions. The tests concluded that the inverted pendulum models can be used to calculate the body centre of mass displacement. The double inverted pendulum model results are more accurate compared with the single inverted pendulum model. During rough sea conditions, the body movement and postural response of seafarers are increased in order to keep themselves upright. The body is furthermore exposed to a fluctuating ground reaction force which may lead to the progression of osteoarthritis and musculoskeletal injuries. The Dorsiflexometer proved to be capable of conducting repeatable assessments and yielding accurate results which can be used to distinguish between balance capabilities. / AFRIKKANSE OPSOMMING: Die Dorsiflexometer is ’n apparaat wat die balansvermoë van pasiënte analiseer. Die masjien is ontwerp en vervaardig weens die groot behoefte aan fisiologiese balans assesserings toerusting wat dinamiese toetse in die mediese sektor kan bepaal. Dit word bereik deur pasiënte se liggaamsreaksie in die sagittale vlak te meet en te assesseer. Die Dorsiflexometer is beheerbaar vanaf ’n rekenaar sagteware koppelvlak program. Die masjien maak gebruik van ’n enkele kragplaat om pasiënte se balans statistieke te meet. Hierdie balans statistieke wat die pasiënte se balans vermoë beskryf en karakteriseer behels die sogenaamde: swaai indeks, balans telling, posturale stabiliteit indeks en die radius parameter. ’n Enkel en dubbel inverse slinger model van die liggaam is afgelei. Hierdie modelle maak gebruik van ’n pasiënt se kragplaat metings en sy liggaamlike parameters om die swaartepunt tydens beweging te bereken. Drie eksperimente, waarin 48 persone betrokke was, is gedoen. Die eksperimente is gedoen om die apparaat se bevoegdheid te bewys, die akkuraatheid van altwee inverse slinger modelle te toets en verder die balans van seevaarders op die Antarktiese navorsings en toevoer skip tydens rowwe see toestande te analiseer. Die toetse het bewys dat die inverse modelle gebruik kan word om die liggaam se swaartepunt te bereken. Die dubbel inverse slinger model resultate is wel akkurater as die enkel slinger model. Daar is bevind dat seevaarders van meer liggaamsbeweging en posturale reaksies gebruik moet maak om orent te bly tydens rowwe seetoestande. Verder word hul liggame blootgestel aan ’n wisselende grond reaksie krag wat kan lei tot die ontwikkeling van osteoarthritis en muskuloskeletale beserings. Die Dorsiflexometer is bewys as ’n aparaat wat wat akurate resultate lewer vir herhaalbare assesserings. Dit kan gebruik word om te onderskei tussen verskillende balans vermoëns.

A relação entre a anatomia mandibular e a ocorrência de fratura indesejada de mandíbula na osteotomia sagital é alvo de estudos. A literatura mostra a existência de diferentes conformações anatômicas da mandíbula, porém não há estudos nessa área direcionados a indivíduos com fissura labiopalatina. Também não há na literatura estudos que mostrem as diferenças morfológicas da mandíbula relacionadas a secção transversal entre primeiro e segundo molar e sua relação com implicações na cirurgia ortognática. O objetivo do presente estudo foi avaliar a morfologia da região entre primeiro e segundo molar inferior e classificar a prevalência dos tipos mandibulares dentro de cada grupo. Foram realizadas análises e medições das reformatações das tomografias da região de molares, bilateralmente, de indivíduos Classe III, com fissura labiopalatina unilateral (Grupo FLP) submetidos à cirurgia ortognática para recuo mandibular no Hospital de Reabilitação de Anomalias Craniofaciais e de indivíduos Classe III, sem fissura (Grupo Controle) do banco de dados do Departamento de Cirurgia e Estomatologia da Faculdade de Odontologia de Bauru. Foram realizadas duas medidas lineares e uma medida angular. As hemimandíbulas foram classificadas segundo a profundidade da fossa mandibular em: Tipo a - 0 e 1mm; Tipo b - 1,1 e 2mm; Tipo c - 2,1 e 3mm; Tipo d - maior que 3,1mm. Foram analisadas 200 hemimandíbulas no Grupo FLP e 100 no Grupo Controle. Os resultados mostraram que não houve diferença entre os grupos quanto a classificação das mandíbulas segunda a profundidade da fossa, sendo o grupo b o mais prevalente, mas houve diferença em relação a angulação e a altura da mandíbula . Também foi notada uma relação entre a altura da mandíbula e a sua angulação em ambos os grupos. Assim, pode ser observada a grande variação morfológica dessa região, tanto para o grupo com fissura labiopalatina, quanto para o grupo controle. / The relationship between a mandibular anatomy and an occurrence of an undesirable jaw fracture in a sagittal osteotomy is the subject of the studies. The literature shows an existence of different anatomical conformations of the mandible, but there are no studies on the area directed to individuals with cleft lip and palate. There are not in the literature, studies that show a prevalence of mandibular types and the relation of these anatomical variations with orthognathic surgery implications. The objective of the present study was evaluate the morphology of the region between the first and second lower molars and analyze the prevalence of mandibular types within each sample group. Analyzes and measurements of the CT scans were performed bilaterally on Class III patients with unilateral cleft lip and palate (CLP Group) submitted to orthognathic surgery for mandibular retreatment at the Hospital for Rehabilitation of Craniofacial Anomalies and Class III individuals, without Fissure (Control Group) of the database of the Department of Stomatology of the Faculty of Dentistry of Bauru. Two linear measurements and one angular measurement were performed. The half of mandibles were classified according to the depth of the mandibular fossa in: Type a - 0 and 1mm; Type b - 1.1 and 2mm; Type c - 2.1 and 3 mm; Type d - greater than 3.1mm. Two hundred half of mandibles were analyzed in the CLP Group and 100 in the Control Group. The results showed that there was no difference between the groups regarding the classification of the mandibles according to the depth of the fossa, being group b the most prevalent, but there was difference in relation to the angulation and the height of the mandible. It was also noted a relationship between the height of the mandible and its angulation in both groups. Thus, the great anatomical variation of this region can be observed, both for the group with fissure and for the group without fissure.

Foram incluídos no estudo 32 prontuários de pacientes, divididos em dois grupos de dezesseis. O primeiro grupo (Grupo 1) de pacientes foi submetido a cirurgia bimaxilar com a sequência clássica do procedimento, no qual a maxila foi reposicionada primeiro que a mandíbula. O segundo grupo (Grupo 2) de pacientes sofreu alteração desta sequência, na qual a mandíbula foi reposicionada primeiro que a maxila. A mensuração para determinar a precisão do reposicionamento dos maxilares foi realizada por sobreposição, pela base do crânio, os traçados obtidos de uma telerradiografia lateral realizada com, no máximo, 30 dias de pós-operatório e os traçados de planejamento. A análise estatística foi realizada utilizando o teste t pareado para verificar a diferença entre os valores previstos e os obtidos em cada grupo. O teste t de Student para amostras independentes foi utilizado para comparar o erro de previsão entre os dois grupos. Na amostra estudada, ambas as sequências operatórias permitiram precisão satisfatória. O erro de previsão para as variáveis incisal do incisivo superior (IIS), Ponto A e cúspide mesiovestibular do molar inferior (6i Oclusal), no sentido vertical, foi maior para o Grupo 2, quando comparado ao Grupo 1. O erro de previsão no sentido vertical para o Pogônio (P) foi menor quando a cirurgia foi iniciada pela mandíbula. Em conclusão, embora ambas as sequências cirúrgicas possam ser utilizadas, iniciar a cirurgia pela mandíbula provocou maior imprecisão em relação ao traçado preditivo do que iniciar a cirurgia pela maxila. A sequência clássica, reposicionando a maxila primeiro, resultou em maior precisão no reposicionamento vertical do ponto A, bem como da incisal do incisivo superior e, portanto, da maxila, do ponto de vista estético. Iniciar a cirurgia pela mandíbula permitiu maior precisão na posição vertical do pogônio. / This study aims to evaluate the precision of bimaxillary surgery performed to correct vertical maxillary excess, when the procedure is sequenced by mandibular surgery first or maxillary surgery first. Thirty-two patients were included in this retrospective study, divided into two groups. The first group was composed by patients who received bimaxillary surgery following the classic sequence of repositioning the maxilla first. In the second group patients received bimaxillary surgery by operating the mandible first. The data were tabulated and statistically analyzed. Precision of the maxillo-mandibular repositioning was measured by superimposing, through the cranial base, digital postoperative tracings taken at a maximum of 30 days after surgery to the prediction tracings. The paired t test was used to determine the difference between predicted and obtained values for each group. The Student’s t test for independent samples was applied to compare the prediction error between groups. In this sample, both surgical sequences provided adequate clinical accuracy. The classical sequence, repositioning the maxilla first, resulted in greater accuracy of A point, lower first molar and incisor edge vertical position. Repositioning the mandible first allowed greater precision in the vertical position of pogonion. In conclusion, although both surgical sequences may be used, repositioning the mandible first will result in greater imprecision in relation to the predictive tracing, than repositioning the maxilla first. The classical sequence resulted in greater accuracy in the vertical position of the maxilla, which is key for esthetics. Repositioning the mandible first allowed greater accuracy for the vertical position of pogonion.
