Abstract:

Introduction. The surface area of edentulous jaw has been considered as an important functional and anthropometric parameter. The aim of this study was to assess the surface area of supporting tissue in edentulous jaws of patients with the skeletal class I. Material and Methods. Thin aluminum foils (0.5 mm of thickness) were adapted on plaster surfaces of 139 pairs of edentulous jaws casts. Foils were positioned on a millimeter-paper in order to measure their areas. Additionally, surface areas were measured using a mechanic plan-meter (G. Coradi, Zurich, Switzerland, serial no. 49823). The measurement error was 1%. Skeletal class of edentulous jaws was determined by analysis of lateral cephalometric radiographs, and assessing the ANB (SNA, SNB) angle. Results. The average surface area of edentulous upper jaws was 4654?407 mm2 in males, and 4212?368 mm2 in females. Edentulous lower jaws had average surface area of 2843?339 mm2 in males, and 2334?295 mm2 in females. Statistically significant difference (p<0.001) was found in comparison of surface areas and dimensions of upper and lower edentulous jaws in male and female. ANB values ranged from 2 to 4 degrees. Conclusion. The surface area is an important parameter in the analysis of edentulous jaws. Edentulous jaws in males had greater surface areas and dimensions as compared to females. Edentulous areas on the right side were not absolutely symmetric to areas on the left side.

Abstract:

This study investigated changes in alveolar bone height in free-ranging koalas of different age groups. Twenty-seven free-ranging Queensland koalas (15 female, 12 male), admitted to the Moggill Koala Hospital, Brisbane, were used in this study. Koalas were divided into three groups (young, adult, old) on the basis of tooth wear, each group containing nine animals. Defleshed jaws were examined for the presence of alveolar bone defects. The distance from the cemento-enamel junction and the interproximal crestal alveolar bone height was measured on the buccal aspects of the second and third molars. Jaws were photographed and radiographed. Bone defects (dehiscences and fenestrations) were observed in both jaws and were predominantly located on the buccal aspect of the alveolar process. The loss of height of crestal alveolar bone, relative to the cemento-enamel junction, increased with age, with 25 koalas showing moderate to severe bone loss and only two koalas having none/mild loss levels at all measurement sites. Female koalas had higher frequency of ‘none/mild’ cases of bone loss than did males. There was no variation in levels of alveolar bone loss between the upper and lower jaws or the corresponding right and left arches.

Abstract:

A bond pull test is used to determine the strength of the bond of an electronic interconnect to a circuit board. A standard test consists of clamping and pulling the interconnect with a pair of microscopic jaws. In a successful test, the maximum pulling force registered by the jaws will be the failure load of the interconnect to circuit board bond. However, if the interconnect itself deforms before the bond has failed, then this would constitute an unsuccessful test. This paper reports on a theoretical analysis of the optimal geometry for gripping of a cylindrical interconnect. Upper and lower-bound plasticity models have been used to determine the jaw proportions that will maximize the load for the deformation of the interconnect and that should, therefore, be most likely to allow successful measurement of the bond strength. This theoretical analysis is compared to 2D and 3D non-linear finite element calculations. The 2D finite element models are axi-symmetric approximations of a pull test on a cylindrical interconnect. 3D finite element models take into account the actual jaw geometry and allow simulation of both clamping and pulling stages. The maximum calculated pull forces for both 2D and 3D simulations are in good agreement with the plasticity theory. Preliminary validation of the theory and finite element results has been accomplished through experimental clamping and pulling tests on cylindrical metal rods.

Abstract:

Invasive or uncomfortable procedures especially during healthcare trigger emotions. Technological development of the equipment and systems for monitoring and recording psychophysiological functions enables continuous observation of changes to a situation responding to a situation. The presented study aimed to focus on the analysis of the individual’s affective state. The results reflect the excitation expressed by the subjects’ statements collected with psychological questionnaires. The research group consisted of 49 participants (22 women and 25 men). The measurement protocol included acquiring the electrodermal activity signal, cardiac signals, and accelerometric signals in three axes. Subjective measurements were acquired for affective state using the JAWS questionnaires, for cognitive skills the DST, and for verbal fluency the VFT. The physiological and psychological data were subjected to statistical analysis and then to a machine learning process using different features selection methods (JMI or PCA). The highest accuracy of the kNN classifier was achieved in combination with the JMI method (81.63%) concerning the division complying with the JAWS test results. The classification sensitivity and specificity were 85.71% and 71.43%.

Abstract:

AbstractPurposeSmall field dosimetry is complicated and accuracy in the measurement of total scatter factor (TSF) is crucial for dosimetric calculations, in making optimum intensity-modulated radiotherapy plans for treating small target volumes. In this study, we intended to determine the TSF measuring properties of CC01 and CC04 detectors for field sizes ranging from sub-centimetre to the centimetre fields.Material and methodsCC01 and CC04 chamber detectors were used to measure TSF for 6 and 18 MV photon beam delivered from the linear accelerator, through small fields in a water phantom. Small fields were created by collimator jaws and multi-leaf collimators separately, with field sizes ranging from 0·6 to 10 cm2 and 0·5 to 20 cm2, respectively.ResultsCC01 measured TSF at all the given field sizes created by jaws and multi-leaf collimators for both 6 and 18 MV beams whereas CC04 could not measure TSF for field sizes <1 cm2 due to volume averaging and perturbation effects.ConclusionCC01 was shown to be effective for measurement of TSF in sub-centimetre field sizes. CC01 can be employed to measure other dosimetric quantities in small fields using different energy beams.

Abstract:

The eight types of micro-grippers with silicon were simulated by ANSYS and fabricated by MEMS(Micro Electro Mechanical System) process. Each type of micro-grippers had a small difference in design shape such as beam width, gap between beams. In order to modify design shape, these micro-grippers were estimated and simulated in point of structure, actuation characteristics by changing design factors. Micro-grippers were composed of five parts which were piezoelectric actuation part, fixing part, rotation arms, the block and gripping jaws. The shape of gripping jaws was designed as the teeth of a saw to reduce adhesion force by decreasing the contact area. The 10.2 µm movement by piezoelectric actuator at 120 V generated the 142.8 µm gripping range of a micro-gripper in real measurement. In the case of simulation result, the gripping range of 162 µm was generated at the same condition. This gripping range was enough to handle small objects like micro-parts

Abstract:

This project investigates methods for calibrating and functional testing an Engine Vibration Measurement Equipment. The equipment uses accelerometers to measure vibrations on the JAS 39 Gripen aircraft engine to ensure that the engine is correctly installed. A model for emulating the electronic signals generated by the accelerometers was created in Simulink and different ways for utilizing the model as a part of a complete test system were examined. Upon examination of different calibration methods it was found that a complete test system needs to have the ability to both send electrical signals directly into the EVME as well as a way of testing the accelerometers mechanically. Both short- and long-term solutions fulfilling these requirements were prepared.

Abstract:

Background: Registering a true maximum bite force on the most commonly-used force transducers is problematic. It is often believed that this is related mainly to discomfort and the fear of breaking teeth. Objectives: The aim of the project was to compare the suitability of different bite force measuring transducers including ones which were designed to improve subject comfort. The transducers used were a traditional strain-gauge transducer with and without covering with ethylene vinyl acetate (EVA) sheets, and a newly-developed pressure transducer. Methods: Five separate studies were performed in this project. The experiments were carried out on human volunteer subjects (aged 24 to 41 years). They were all dentate with no missing anterior teeth and with no crowns on these teeth. The following procedures were used in some or all of the studies: measurement of MVBF, electrical stimulation of the masseter muscle, and EMG recording from two pairs of jaw closing muscles. Results: The highest MVBF values were recorded on the pressure transducer, mean (± S.D.) 464 N ± 224 N; followed by the strain-gauge transducer with EVA sheets, 243 ± 80 N; and last of all the strain-gauge transducer with silicone indices, 165 ± 35 N; or acrylic indices, 163 ± 82 N. Significantly higher maximum potential bite forces were predicted by twitch interpolation for the pressure transducer (730 ± 199 N) than for the strain-gauge transducer with EVA sheets, 354 ± 67 N (Paired t test, P < 0.05). Significantly higher EMGs of the masseter and anterior temporalis muscles were found to be associated with MVBFs on the pressure transducer than with MVBFs on the strain-gauge transducer with EVA sheets (Paired t test, P < 0.05). Conclusions: It is concluded that: a) the pressure transducer system and to a lesser extent the strain-gauge transducer covered with EVA sheets seemed to overcome the fear associated with biting on the hard surfaces of the strain-gauge transducer alone; b) the pressure transducer may have some multi-directional capabilities which allow for total bite forces, or at least larger parts of them, to be recorded than on a uni-directional strain-gauge transducer.

Abstract:

Forensic anthropologists are often asked to analyze and interpret human remains that have been modified or damaged by predators and/or scavengers (White 2000; James et al. 2005; Dupras et al. 2006). The goal of this study is to determine whether it is possible to distinguish carnivore tooth mark characteristics from other carnivore tooth mark characteristics through two separate analyses: first by examination of tooth pitting and second from carnivore tooth and jaw measurements. This is accomplished by visual analysis and measurements of tooth pits left on faunal bones processed by an experimental wolf group as well as carnivore tooth and jaw measurements from a study done by Murmann et al. (2006) and measurements done by the author from samples located in the Philip L. Wright Zoological Museum. In the first analysis, independent t-tests demonstrate that pit lengths found on long bone epiphyses that are less than 4mm are likely to be made by carnivores the same size or smaller than a jackal. If pit lengths found on long bone epiphyses are between 4mm and 6mm, they are likely to have been made by carnivores roughly the same size as baboons, bears, dogs, and wolves and if the pit lengths found on long bone epiphyses measure greater than 6mm, they are likely made by carnivores about the same size as hyenas and lions. Pit breadths between 2mm and 4mm found on long bone epiphyses are associated with carnivores in the size bracket of baboons, jackals, bears and dogs. Pit breadths larger than 4mm found on long bone epiphyses are associated with larger carnivores such as hyenas, lions and wolves. The second analysis, a discriminant function analysis using tooth and jaw measurements distinguishes carnivore tooth mark characteristics from other carnivore tooth mark characteristics left on scavenged remains through the use of the Murmann et al. (2006) measurements with an accuracy of between 75.5% based on leave one out cross-validation and 78.3% based on the accuracy of classification of a test sample.

Abstract:

Background: Maximal voluntary occlusal bite force (MVOBF) is the maximal force applied by the jaw muscles in dental occlusion. MVOBF is one parameter for functional capacity of the jaw system. Aim: To evaluate MVOBF in different positions in the bite and to evaluate possible intra-individual differences between sessions. Methods: MVOBF was measured with an electronic bite force device, with transducers sensitive to force, in 20 healthy men (mean 24.5 years). Eligibility of participants was full dental occlusion, Angle Class I relation, no diagnosis according to Diagnostic criteria for temporomandibular disorders. The test included three repeated measurements on each site: first molar right, first molar left and central incisor, in random order, with test-retest study design. Unpaired T-test was used to test the MVOBF in different positions in the bite and paired T-test for possible intra-individual differences between sessions. A post hoc test for repeated measure one-way ANOVA was added. Results: MVOBF in different positions in the bite was lower in the incisor area compared with the molar region (P<0.0001), but similar between right and left molar side (P=0.48 and P= 0.96, respectively). No intra-individual differences between sessions (molar right P= 0.40; molar left P= 0.81; incisor area P= 0.66). The intra-individual variability for repeated measurements showed variability for incisor area (P= 0.007), but not for molar right and left region (P=0.95 and P=0.49, respectively). Conclusion: The results may provide reference values for MVOBF in young adult men, to be compared with men with pain or dysfunction in the jaw system.

Objetivo: este estudo retrospectivo avaliou a acurácia entre os resultados obtidos e o planejamento assistido por computador (PAC) em cirurgia ortognática por meio do uso de modelos de superfície tridimensionais (3D) para aplicação em algoritmo de proximidade iterativa de pontos (PIP) e produção de mapas de cores por meio de programa computacional de engenharia reversa. Material e Métodos: a partir de arquivos de tomografia computadorizada cone-beam (TCFC) de 25 pacientes submetidos à cirurgia ortognática bimaxilar, foram gerados modelos 3D do PAC e pós-operatório em formato de arquivos STL (M0 e M1, respectivamente). Os M0 e M1 foram importados para programa computacional Geomagic Wrap, sendo aplicada a função de registro por meio do algoritmo PIP para alinhamento automático e cálculos dos desvios médios (MD, MD +, MD -, SD) e quadrado médio da raiz (RMS). Os mapas de cores foram gerados para avaliar a congruência qualitativa entre M0 e M1. A partir da análise dos desvios, os RMS(s) foram definidos como ‘3D Error’ que foi utilizado como indicador de mensuração de acurácia. As características da amostra foram apresentadas por análises de estatística descritiva. Para avaliar a reprodutibilidade do método, o fluxo de trabalho foi realizado por dois avaliadores independentes. Os testes t foram utilizados para avaliar as médias de MD, MD +, MD-, SD e ‘3D Error’, segundo a hipótese de todos os valores fossem menores ou igual a - 2 mm e maiores ou igual a 2 mm. Resultados: foram encontradas altas correlações intra e inter-avaliadores, favorecendo a reprodutibilidade do fluxo de trabalho no Geomagic Wrap. Testes t rejeitaram a hipótese de que os valores MDs e ‘3D Error’ eram menores que - 2 mm e maiores que 2 mm. Conclusão: este estudo apresentou a média de ‘3D Error’ (1,27 mm) estava dentro dos padrões de sucesso clínico inferior a 2 mm. O algoritmo PIP no Geomagic Wrap forneceu um método reprodutível para relacionar as malhas de superfície dos modelos 3D, e mapas de cores foram gerados para avaliar a congruência 3D. No entanto, não há respostas para todos os parâmetros metodológicos em relação à avaliação da acurácia em cirurgia ortognática.
Purpose: The aim of this retrospective study was to evaluate the accuracy between actual outcomes and virtual surgical planning (VSP) in orthognathic surgery regarding the use of three-dimensional (3D) surface models for registration using ICP algorithm and color maps by reverse engineering software. Materials and Methods: Construction of planning and postoperative 3D models in STL files format (M0 and M1, respectively) from CBCTs of 25 subjects who had been submitted to bimaxillary orthognathic surgery was performed. The M0 and M1 were sent to Geomagic Wrap Software in automatic alignment surface meshes order of M0 and M1 for registration using the ICP algorithm to calculate mean deviation (MD, MD+, MD-, SD) and root mean square (RMS). Color maps were generated to assess qualitative congruence between M0 and M1. From deviation analysis, the RMS(s) were defined as 3D Error which behaved as a measurement indicator of accuracy. The sample characteristics were shown by descriptive statistics. To evaluate the reproducibility of this method, the workflow was performed by two independent evaluators multiple times. t tests were used to assess whether all means of MD, MD+, MD-, SD and 3D Error values would be lower than - 2 mm and greater than 2 mm. Results: high intra and inter evaluators correlation were found, supporting the reproducibility of the workflow in Geomagic Wrap software. t tests proved that all MD(s) and 3D Error values were greater than - 2 mm and lower than 2 mm. Conclusion: This study showed 3D error mean (1,27 mm) within the standards of clinical success lower than 2 mm. ICP algorithm in Geomagic Wrap software provided a reproducible method of alignment between 3D models (surface meshes) and generated color maps to evaluate 3D congruence, but did not answer all methodological parameters regarding the assessment of accuracy in orthognathic surgery.

Abstract:

Jádrem této disertační práce bylo studovat optické a elektrické charakteristiky tenkovrstvých elektroluminiscenčních součástek řízených střídavým proudem (ACTFEL) a zejména vliv procesu stárnutí luminiforů na jejich optické a elektrické vlastnosti. Cílem této studie měl být příspěvek ke zvýšení celkové účinnosti luminoforů, vyjádřené pomocí jasu, účinnosti a stability. Vzhledem k tomu, že současnou dominantní technologií plochých obrazovek je LCD, musí se další alternativní technologie plošných displejů porovnávat s LCD. Výhodou ACTFEL displejů proti LCD je lepší rozlišení, větší teplotní rozsah činnosti, větší čtecí úhel, či možnost čtení při mnohem vyšší intenzitě pozadí. Na druhou stranu je jejich nevýhodou vyšší energetická náročnost, problém s odpovídající barevností tří základních barev a podstatně vyšší napětí nutné pro činnost displeje. K dosažení tohoto cíle jsme provedli optická, elektrická a optoelektrická měření ACTFEL struktur a ZnS:Mn luminoforů. Navíc jsme studovali vliv dotování vrstvy pomocí KCl na chování mikrostruktury a na elektroluminiscenční vlastnosti (zejména na jas a světelnou účinnost) ZnS:Mn luminoforů. Provedli jsme i některá, ne zcela obvyklá, měření ACTFEL součástek. Vypočítali jsme i rozptylový poměr nabitých barevných center a simulovali transportní charakteristiky v ACTFEL součástkách. Studovali jsme vliv stárnutí dvou typů ZnS:Mn luminoforů (s vrstvou napařenou či získanou pomocí epitaxe atomových vrstev) monitorováním závislostí svítivost-napětí (L-V), velikost vnitřního náboje - elektrické pole luminoforu (Q-Fp) a kapacitance-napětí (C-V) ve zvolených časových intervalech v průběhu stárnutí. Provedli jsme krátkodobá i dlouhodobá měření a pokusili jsme se i o vizualizaci struktury luminoforu se subvlnovým rozlišením pomocí optického rastrovacího mikroskopu pracujícího v blízkém poli (SNOM). Na praktickém případu zeleného Zn2GeO4:Mn (2% Mn) ACTFEL displeje, pracujícího při 50 Hz, jsme také studovali stabilitu svítivosti pomocí měření závislosti svítivosti na napětí (L-V) a světelné účinnosti na napětí (eta-V). Přitom byl zhodnocen význam těchto charakteristik. Nezanedbatelnou a neoddělitelnou součástí této práce je i její pedagogický aspekt. Předložený text by mohl být využit i jako učebnice pro studenty na mé univerzitě v Lybii.

Abstract:

The development of the facial bones is particularly important in the fields of paediatric dentistry and orthodontics. Dental students and dental practitioners who do not specialize in those subjects should have an appreciation of the subject to be aware of the changes to the face and jaws they are seeing in patients under continuous care as they grow, mature, and age. Human beings increase in both size and complexity during the growth period which lasts from conception until maturity at about 16 to 18 years of age. As we have seen in Chapters 8, 1, 19, 21, and 32, most of the increase in complexity occurs during the pre-embryonic and embryonic phases of prenatal development although changes still occur in many organs and tissues well into post-natal life. Size increase is also rapid prenatally and continues throughout the remainder of the growth period although the growth rate changes. Changes in overall size may occur in mature individuals due to obesity or other pathological conditions but this is not growth. Growth in overall size can be studied by examining the changes with age in easily measured parameters such as height and weight. There are two ways in which such data can be presented as shown in Figure 33.1. A distance curve is the simplest method illustrated in Figure 33.1A by plotting height against age on a graph. Changes in the rate of growth are demonstrated more clearly by plotting the increment in the measurement per unit of time such as the increase in height per year against age; this is a velocity curve shown in Figure 33.1B. You can see in Figure 33.1A that height increases more rapidly around the age of 14; the velocity curve in Figure 33.1B makes the rapid growth at this age much clearer. If distance curves are plotted for different body components, the curves show specific characteristics. The overall growth of the body is accurately indicated by measures of height and weight; these measurements plotted against age produce the somatic growth curve shown in Figure 33.2. Growth is rapid in the prenatal and early post-natal period then begins to slow down after about 4 years of age.

Abstract:

Among the largest Plio-Pleistocene hominin skulls found to date, A.L. 444-2 is bigger, though not by much, than an average female gorilla’s skull. At first glance, A.L. 444-2 assumes a somewhat simian appearance, the outcome of a relatively small braincase combined with an inclined frontal squama and prognathic jaws. However, this apelike appearance is offset by several distinctive hominin features: a very tall face that is much less prognathic than would be expected from the skull’s general simian-like appearance; a deep, vertical mandibulosymphyseal profile; delicate supraorbital elements; and the absence of a supratoral sulcus intervening between the frontal squama and the forward-jutting supraorbital element. Nevertheless, the characteristics that account for the skull’s hominin appearance demonstrate a certain uniqueness, which is manifested in the disproportion between the considerable total height of the face and the great size of its constituent elements (primarily the zygomatic and maxillary bones), on the one hand, and the delicateness of the supraorbital element and the almost negligible degree of its anterior projection, on the other. An apparent unevenness emerges along the vertical axis of the face between its upper portion—the orbits, including the elements above and between them—and its lower portion, that is, the elements below the level of orbitale down to gnathion. Undoubtedly, part of this appearance stems from the heavy, somewhat vertical, deep, and anteriorly bulbous symphyseal region of the mandible. The corresponding region in the African apes, in contrast, is transversely pinched, as its two sides converge downward toward the midline. Furthermore, the region slopes inferoposteriorly; in anterior view, it is tucked under the alveolar element and hence is less exposed than in A.L. 444-2. The preservation of the mandible of A.L. 444-2 and its occlusion with the upper dental arcade afford a unique opportunity to evaluate some of the characteristics of an entire A. afarensis skull. Two standard measurements can be recorded: the distance between gnathion and the estimated site of nasion—a measure of the total height of the face—which is 150 mm, and the distance between gnathion and basion, estimated at 157 mm.

Abstract:

Analysis of depth and the roughness from the chuck jaws indentation investigated by the Olympus LEXT-OLS4000 Laser microscope. Strain gauges were used for measuring the gripping force of the jaws. The three-characteristic movements of an expert who ensured that the work-piece was kept steady and balance did not measurably affect the surface indentation of the work-pieces. The characteristic movement of the non-expert often straddled the left body to the left side while he was twisting the chuck-key has appeared the surface indentations. The depth inspection of them found the inside of surface indentation deeper than outside. Moreover, the results of a strain gauge measurement of all movements both an expert and the non-expert indicated the inside of the jaw had higher the strain than outside. Nevertheless, the results showed the most strain on work-piece surface occurred with the body movement of the non-expert.

Abstract:

Radiolabelled platelet deposition on prosthetic arterial grafts may be used as a method to evaluate antithrombotic drugs but requires large animals or patients and involves artificial flow surfaces. A rabbit model has been developed to investigate platelet uptake following carotid intimal damage.Both carotid arteries of 10 NZW rabbits were exposed by midline incision and intimal damage inflicted by a 3-minute unilateral artery compression using the jaws from non-toothed dissecting forceps mounted on a G-clamp with compression screw. Twenty-four hours later, autologous platelets were labelled with llllndium by the method of Hawker et al [1], The carotid arteries were excised 40 hours later and radiolabelled platelet uptake counted in a well crystal and expressed as a percentage of the activity in 1ml of blood.Total counts (mean ± sem) in the non-traumatised artery were 2.6±0.35×103 which was similar to background at 2.0±0.07×103. Expressed per gm, radioactivity in the traumatised artery at 4.8±0.38×l05/gm was significantly higher than 2.6±0.43×105 in the undamaged carotid (p<0.01). Platelet uptake on the damaged endothelium, expressed as a percentage of the activity in 1ml of blood, at 55.1±9.8 was also significantly higher than 28.6±6.3 percent on the control artery (p<0.01).This inexpensive model allows the precise measurement of radiolabelled platelet uptake on damaged arterial intima and may therefore be used to evaluate antithrombotic drugs and investigate the role of platelets in arterial repair, intimal hyperplasia and the pathogenesis of atheroma.1.
