Abstract:

AbstractDenture labelling is not a new concept in either prosthetic or forensic dentistry and its routine practice has been urged by forensic dentists internationally for many years. Prosthodontists are playing very important role in forensic dentistry as they are concerned with fabrication of various prosthesis which can serve as an important tool for identification. The main objective of this article is to discuss the various methods available for denture marking along with three case reports.

Abstract:

The article presents a scientific overview of the literature on the actual problem restorative dentistry: preparation low-supple atrophied tissue prosthetic bed before the prosthesis patients with complete absence of teeth in the lower jaw. Despite significant progress in prosthetic dentistry, the problem of prosthesis patients with complete absence of teeth on the lower jaw does not lose its relevance. From 15 to 46% of patients aged 45-70 years, need to manufacture complete dentures. One of the factors that directly affect the fixation of complete removable lamellar denture for the lower jaw is a condition of the mucous membrane of prosthetic bed. The most unfavorable for prosthetics full removable laminar dentures is considered as grade 2 mucosa classification Supple. This class is characterized by thinned, stretched and dry mucous membrane of the prosthetic bed. To achieve success in the orthopedic treatment of such patients need to restore the volume and pliability of the mucous membrane of toothless prosthetic bed. A study of the basic methods of surgical, orthopedic, physiotherapy preparation of tissue prosthetic bed toothless lower jaw, and combinations thereof. Of the known methods of noteworthy ways of plastics of the alveolar part of the mandible and increase in volume of soft tissues of the prosthetic bed toothless method Plasmolifting, and the combination of the introduction of autoplasma rich in platelet with the production time immediat dentures with elastic lining. Describes the advantages and disadvantages of the proposed methods. Despite the many different ways of preparation of prosthetic bed before prosthetic treatment, this problem remains unsolved and requires further study.

Abstract:

ABSTRACT Aim Antibiotic prophylaxis guidelines have been developed for health care and dentistry. The authors examined whether dentists were following the 2007 American Heart Association (AHA) and the 2012 American Association of Orthopaedic Surgeons (AAOS) recommendations for antibiotic prophylaxis. Materials and methods A survey was sent to 600 dentists in the south-central region of the United States. The survey examined dentists’ prescribing practices for patients with cardiac and prosthetic joint replacements, antibiotic regimen prescribed, confidence in their prescription decisions, and dentistry's contribution to antibiotic resistance. Results The response rate was 28.7% (n = 172). Dentists followed the 2007 AHA guidelines for patients with a history of infective endocarditis (95%), and cardiac valves repaired with prosthetic materials (76%) or animal/donor tissue (61%). For prosthetic joint replacement, 72% prescribed antibiotic prophylaxis within the first 2 years after placement and 58% continued to prescribe after 2 years. Amoxicillin was the most frequently prescribed antibiotic for cardiac conditions (92%) and prosthetic joint replacements (77%). No significant differences were found in relation to dentists’ gender (p = 0.75), year of graduation (p = 0.71), scope of practice (p = 0.30), and their confidence in their prescription decisions; 73% believed taking multiple doses of antibiotics leads to antibiotic resistance. Conclusion The majority of dentists were following the 2007 AHA guidelines. Confusion regarding the 2012 AAOS guidelines for prosthetic joint replacement was evident. Clinical significance Keeping current with changing antibiotic prophylaxis guidelines ensures dentists are providing the best evidence-based dentistry for their patients.

Abstract:

The paper is a comprehensive but compact review of the literature on the state of illnesses of the human stomatognathic system, related consequences in the form of dental deficiencies, and the resulting need for prosthetic treatment. Types of prosthetic restorations, including implants, as well as new classes of implantable devices called implant-scaffolds with a porous part integrated with a solid core, as well as biological engineering materials with the use of living cells, have been characterized. A review of works on current trends in the technical development of dental prosthetics aiding, called Dentistry 4.0, analogous to the concept of the highest stage of Industry 4.0 of the industrial revolution, has been presented. Authors’ own augmented holistic model of Industry 4.0 has been developed and presented. The studies on the significance of cone-beam computed tomography (CBCT) in planning prosthetic treatment, as well as in the design and manufacture of prosthetic restorations, have been described. The presented and fully digital approach is a radical turnaround in both clinical procedures and the technologies of implant preparation using computer-aided design and manufacturing methods (CAD/CAM) and additive manufacturing (AM) technologies, including selective laser sintering (SLS). The authors’ research illustrates the practical application of the Dentistry 4.0 approach for several types of prosthetic restorations. The development process of the modern approach is being observed all over the world. The use of the principles of the augmented holistic model of Industry 4.0 in advanced dental engineering indicates a change in the traditional relationship between a dentist and a dental engineer. The overall conclusion demonstrates that it is inevitable and extremely beneficial to implement the idea of Dentistry 4.0 following the assumptions of the authors’ own, holistic Industry 4.0 model.

Abstract:

ABSTRACT The goal of any prosthetic procedure must include the establishment of a functional occlusion. It is known that natural teeth have periodontal ligament receptors that protect the teeth from excessive occlusal forces, which can cause trauma to supporting tissues and bone. Although many factors are involved in the neuro-muscular reex actions in natural teeth, there are no specic defense mechanisms against occlusal forces in implant-supported prosthesis. Complications (prosthetic or bony support) reported in follow-up studies underline occlusion as one of the determining factors for success or failure of implants.

ABSTRACT Objective: To evaluate the dental prosthetic status and prosthetic needs of geriatric patients attending the College of Dentistry, Al Jouf University, Kingdom of Saudi Arabia. Materials and Methods: Patients aged 60 years and above were included in this study. The World Health Organization oral health assessment pro forma was employed to record the data pertaining to the prosthetic status and prosthetic treatment needs of participants. Data obtained were analyzed using the Statistical Package for the Social Sciences (SPSS, Chicago, IL, USA) Version 20.0. Differences in proportions were compared using the Chi-square test. Results: Out of 286 edentulous patients, 69.06% needed some form of prosthetic treatment, 73.77% did not have any prosthesis in upper arch, and 80.06% did not have any prosthesis in lower arch. Out of 162 males, 32.09% and 26.54% had prosthesis in upper and lower arch, respectively. Among 124 females, 18.54% and 19.35% had prosthesis in upper and lower arch, respectively. In males, the need for any type of prosthesis in upper and lower arch was 68.51% and 75.92%, respectively. In females, the need for prosthesis in upper and lower arch was 57.25% and 72.58%, respectively. The need for multiunit prosthesis was more in both arches in both genders. The need for complete denture and combination of single- or multiunit prosthesis was more among the males as compared to females in maxilla and vice versa for mandible. Conclusion: The observations of this study propose that the greater part of the prosthetic needs were insufficient among the geriatric people.

Abstract:

ABSTRACT Anophthalmia (The loss an eye) not only impairs patient's vision but also create a noticeable deformity on facial appearance and esthetics. The condition is a psychological distress for the patient interrupting his routine work. 'sarvendriyanam nayanam pradhanum’ states vision to be the supreme among all the senses. A prosthodontist as an integral member of the craniofacial rehabilitation team can help raise the spirits and ease the mind of the affected. Among various approaches, customized ocular prosthesis achieves better comfort and function between prosthesis and orbital tissues. This is a case report of a female patient of age 22 years had lost her eye as a child due to trauma and the above mentioned prosthesis was planned and fabricated to enhance appearance and boost her confidence. Getting eyesight back is not always possible, but maxillofacial prosthetics can help to reduce the pain of psychological embarrassment. Artistic skills are needed in providing a natural look to the prosthesis; this technique may help in a naturally appearing prosthesis with lesser artistic skills.

Abstract:

Proporcionar longevidade clínica às restaurações cerâmicas deve ser um dos objetivos principais dos cirurgiões-dentistas ao realizar um tratamento protético. Objetivo: Correlacionar a influência do tratamento interno do substrato cerâmico e do tipo de polimento da superfície cerâmica externa com a efetividade clínica de restaurações com sistemas cerâmicos livres de metal. Métodos: Foram elaborados quatro artigos científicos. No Capítulo 1, apresentou-se um estudo de revisão da literatura a respeito dos métodos de tratamento de superfície para as cerâmicas reforçadas por óxido de zircônia e a implicação clínica deste procedimento na resistência da união deste sistema cerâmico quando realizada cimentação adesiva. Os Capítulos de 2 a 4 são representativos de trabalhos in vitro. No Capítulo 2, foi delineado um experimento com o objetivo de avaliar a influência do tratamento da superfície interna da cerâmica e do tipo de cimento (resinoso dual ou autoadesivo) sobre a resistência da união da interface cerâmicacimento por meio de ensaio de microcisalhamento. Os tratamentos de superfície avaliados foram: condicionamento com ácido fluorídrico a 10%, jateamento com óxido de alumínio 110μm, silicatização e junção de jateamento com óxido de alumínio 110μm e aplicação de um agente silano específicos. O teste foi realizado após o período de 24 horas e os resultados expressos em MPa. Adicionalmente, foi avaliada quantitativamente e qualitativamente a modificação promovida na superfície interna do substrato cerâmico por cada um dos tratamentos de superfície avaliados. No Capítulo 3, o mesmo delineamento executado no Capítulo 2 foi realizado, porém avaliando-se a resistência à degradação hidrolítica promovida pelos mesmos métodos de tratamento da superfície interna da cerâmica, com a realização do ensaio de resistência da união ao microcisalhamento após 24 horas e seis meses de armazenagem em água. No Capítulo 4, foi avaliada a eficácia de diferentes métodos de polimento da superfície cerâmica externa por meio de um ensaio de rugosidade de superfície e microscopia de força atômica, sendo ainda realizada a comparação entre os sistemas cerâmicos pelo ensaio de resistência à tração diametral. Conclusões: Com este trabalho foi possível determinar a importância do tratamento da superfície interna das cerâmicas previamente à cimentação adesiva, objetivando aprimorar a resistência da união da interface cerâmica-cimento, conferindo longevidade às restaurações cerâmicas. Com este propósito, para sistemas cerâmicos reforçados por zircônia, tratamentos de superfície que promovam modificações mecânicas e químicas da superfície cerâmica devem ser utilizados. Também foi possível observar que as restaurações cerâmicas depois de cimentadas e ajustadas clinicamente, devem ser submetidas a técnicas de polimento, sendo que a efetividade desta etapa é dependente da técnica de polimento executada.

Abstract:

Apesar dos pesquisadores afirmarem que os materiais odontológicos restauradores, devido às suas diferentes propriedades mecânicas, influenciam na transmissão da carga para os tecidos de suporte, não foi encontrada comprovação científica concludente. Os trabalhos de análise da distribuição da carga oclusal com diferentes materiais de reconstrução protética não são concordantes em seus resultados. Assim, diante da importância da seleção de materiais restauradores protéticos no prognóstico da reabilitação oral, este trabalho se propôs a estudar a influência de coroas protéticas metalo-cerâmica e de resina, cimentadas no canino, na transmissão de tensões para o tecido ósseo em mandíbulas frescas de cães, utilizando o método de interferometria holográfica de dupla exposição. Seis hemi-mandíbulas frescas de cães da espécie Canis familiares foram fixadas em um dispositivo para garantir a invariabilidade da força aplicada durante o experimento. Uma carga de 0,98 N foi aplicada sobre as coroas, seguindo o longo eixo do dente. Pelo método de interferometria holográfica, foram obtidos 12 hologramas, 6 para cada grupo de amostras. As coroas metalo-cerâmicas apresentaram maior deslocamento, com movimento de intrusão no alvéolo, em relação às de resina. Os microdeslocamentos resultantes nas hemimandíbulas demonstraram comportamentos semelhantes de deflexão, porém, não foram encontradas diferenças estatisticamente significantes na distribuição das tensões ao osso, com relação aos dois tipos de coroas consideradas, demonstrando a influência da presença do ligamento periodontal.
Although researches assert that restoring dental material, due to their different mechanical properties, influences at load transmission to support tissues, it was not find any conclusive scientific evidence. Researches with finite element, implants and different prosthetic reconstruction material do not have an agreement in terms of results. So, considering the importance of prosthetic restoring material selection on oral rehabilitate prognosis, this assignment studied the influence of metaloceramic and resin prosthetics crowns, cemented on canine, during stress transmission to bony tissue of post-mortem dog mandibles, using double exposure holographic interferometry method. Three fresh mandibles were split into 6 hemi-mandibles, which were fixed in a proper device in order to assure the same applied force during the whole experiment. A 0,98 N load was applied to the crowns, following the long axis of the tooth. It was collect 12 holograms, 6 for each sample group. Metaloceramic crowns presented larger intrusion micromovement in the alveolus, comparing that of resin ones. The resulting micromovings in the hemimandibles presented similar deflecting behaviour. However, significant statistical differences on bone tension distribution have not been found, concerning the two types of previously referred crowns, demonstrating the influence of periodontal ligament.

ENGLISH ABSTRACT: Removable Prosthetic Dentistry (PRO400) is a fourth year module of the undergraduate dentistry programme which consists of a large clinical component. After reviewing relevant literature and conducting module evaluations, clinical tests were introduced and implemented in 2008 as an additional clinical assessment method. The intention of introducing the clinical tests was an attempt to ensure that students were assessed fairly, that their theoretical knowledge and the ability to apply it clinically were properly assessed, and to provide feedback on their clinical performance. The purpose of this concurrent mixed methods study was to compare the relationship between the students‟ performance in the clinical tests and daily clinical grades with their theoretical performance in the PRO400 module. The second part of the study explored the academic staff s‟ perceptions of the clinical test as clinical assessment tool in the PRO400 module. The case study design enabled the researcher to explore the question at hand in considerable depth. The mixed methods approach was useful to capture the best of both the qualitative and quantitative approaches. For the quantitative data-collection, record reviews of the results of fourth-year dental students‟ who completed the PRO400 module at the end of 2007 were used, and included 110 students. For the qualitative component three full-time lecturers within the Prosthetic department were interviewed. The clinical test marks and clinical session marks of all the students (n=109) in PRO400 were compared to their theory mark of that year. The tests marks were entered into a spreadsheet in Microsoft Excel and the data analysis was done with the assistance of a statistician. The analytical abstraction method was used to assist with the qualitative data analysis; first the basic level of analysis was done in the narrative form, followed by second higher level of data analysis. The basic and higher levels of analysis were discussed under the following themes: clinical tests, student performances, alignment of theory and clinical assessment and personal influence on supervisors‟ assessment practices and attitude. Role-taking and the supervisors‟ perceptions and concerns regarding the students were explored as emergent themes. The quantitative findings were displayed using tables and graphs. Forty five students. clinical marks were 10% higher than their theory mark, while only 8 students. theory marks were 10% higher than their clinical test mark. There appeared to be hardly any relationship between the students. clinical daily grade assessment marks and their theory marks. The average theory mark was 47%, the average clinical test marks were 55% and the average daily clinical grade was 63%. Integration of the data obtained from the different data collection methods was done at the level of data interpretation. The clinical test as an assessment tool is well accepted by the supervisors and they agreed that it is more reliable and accurate than the clinical daily grade assessment method. The quantitative findings relate well to other reported studies that concluded that the daily grade was poorly correlated with the competency exams (a similar phenomenon in the clinical test of the PRO400 module). From the findings of this study it appeared that there is a better correlation of the clinical test mark and the theory mark, than clinical daily mark and the theory mark. This finding related well with the lecturers. views that the clinical tests were more reliable as a clinical assessment tool than the daily clinical mark.
AFRIKAANSE OPSOMMING: "Removable Prosthetic Dentistry (PRO400)" is 'n vierdejaar-module in die voorgraadse tandheelkundeprogram wat 'n groot kliniese komponent bevat. Na 'n oorsig gedoen is van die relevante literatuur, en nadat die module-evaluering afgehandel is, is kliniese toetse in 2008 ingevoer en geimplementeer as 'n bykomende metode van kliniese assessering. Die kliniese toetse is ingestel in 'n poging om te verseker dat studente se teoretiese kennis en hul vermoe om dit klinies toe te pas op . regverdige wyse geassesseer word en om terugvoer te kan gee oor die studente se kliniese prestasie. Die doel van hierdie studie, waarin gelyktydige gemengde metodes gebruik is, was om die verband tussen die studente se prestasie in die kliniese toetse, asook hul daaglikse kliniese punte en hul teoretiese prestasie in die PRO400-module vas te stel. Die tweede deel van die studie het ondersoek ingestel na die akademiese personeel se persepsies van die kliniese toets as 'n instrument vir kliniese assessering in die PRO400-module. 'n Dwarssnit-gevallestudie-ontwerp is gebruik en 'n gemengdemetode-benadering was nuttig om sowel kwalitatiewe as kwantitatiewe data in te samel. Vir die kwantitatiewe data-insamelingverslae is die uitslae van 109 vierdejaar-tandeheelkundestudente in die PRO400-module aan die einde van 2007 gebruik. Vir die kwalitatiewe data-insameling is onderhoude gevoer met drie voltydse dosente in die Prostetiese Tandheelkunde-departement. Die kliniese toetspunte en die kliniese sessiepunte van al die studente (n=109) in die PRO400-module is met hul teoriepunte van daardie jaar vergelyk. Die toetspunte is op 'n sigblad in Microsoft Excel ingevoer en die data-analise is met die hulp van 'n statistikus gedoen. Die analitiese abstraksiemetode is vir die analise van die kwalitatiewe data gebruik. Die basiese vlak van data-analise in die narratiewe vorm is eerste gedoen. Dit is gevolg deur 'n tweede, hoervlak-data-analise. Die basiese en hoer vlakke van analise is onder die volgende temas bespreek: kliniese toetse, studenteprestasie, ooreenstemming van teorie en kliniese assessering, en persoonlike invloed op studieleiers se assesseringspraktyke en houding. Rol-aanneming en die studieleiers se persepsies, asook kwessies rakende die studente is as ontluikende temas ondersoek. Die resultate van hierdie studie het aangetoon dat die kliniese punte van 45 studente 10% hoër was as hul teoriepunte, en dat slegs agt studente se teoriepunte 10% hoër as hul kliniese toetspunte was. Dit het geblyk dat daar feitlik geen verband was tussen die studente se kliniese daaglikse assesseringspunte en hul teoriepunte nie. Die gemiddelde teoriepunt was 47%, die gemiddelde kliniese toetspunt was 55% en die gemiddelde daaglikse kliniese punt was 63%. Al die studieleiers het die kliniese toets as assesseringsinstrument goed aanvaar en hulle het saamgestem dat dit meer betroubaar en akkuraat is as die daaglikse kliniese assesseringsmetode. Die kwantitatiewe bevindings hou goed verband met dié van soortgelyke studies waarin daar bevind is dat die daaglikse prestasie swak gekorreleer het met die bevoegdheidseksamen (ŉ soortgelyke beginsel as die kliniese toets van die Pro400). Dit het ook uit die bevindings van hierdie navorsing geblyk dat daar ŉ beter korrelasie is tussen die kliniese toetspunt en die teoriepunt as tussen die daaglikse kliniese punt en die teoriepunt. Hierdie bevinding het ŉ duidelike verband getoon met die dosente se siening dat die kliniese toetse as ŉ kliniese assesseringsinstrument meer betroubaar is as die daaglikse kliniese punt in die PRO400-module in die Tandheelkunde-program.

Abstract:

Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Medicina Dentária
Introdução: A evolução das tecnologias em todas as áreas de atividade tem mudado a maneira como se aborda os desafios que são impostos nos dias de hoje. Na medicina dentária tem acontecido o mesmo que na área da saúde em geral, uma resistência enorme às novas técnicas e tecnologias, mas o que é certo é que a era digital esta cada vez mais implantada e a ganhar sobre essa resistência. Os sistemas CAD/CAM já fazem parte integrante da reabilitação dentária, principalmente por via dos laboratórios dentários, mas também no consultório com o sistema CEREC que conseguiu colocar a tecnologia CAM/CAM em consultório ao dispor do médico, dentista e dos pacientes. Objetivos: Verificar, através de uma revisão bibliográfica a evolução dos sistemas CAD/CAM CEREC nos últimos anos. Pretende-se verificar a eficácia clinica deste sistema propriamente dito nos seus diversos materiais para as reabilitações de prótese fixa e reabilitações sobre impantes. Materiais e métodos: Na elaboração desta dissertação foi realizada uma revisão bibliográfica no período que vai desde 1994 até Março de 2015. Foram utilizadas bases de dados como Pubmed (medline), Elsevier, Scielo e GoogleAcademic, com as palavras-chave: “digital prosthetic dentistry”; “dental cad/cam”; “dental ceramics”; “CEREC”; “sistema CEREC”; “materiais CEREC”. Resultados: Nesta revisão foram verificados estudos que mostraram que reabilitações realizadas pelos sistemas CAM/CAM CEREC tiveram bom comportamento clinico nas diversas valências, estética, adaptação marginal, resistência ao desgaste entre outros parâmetros clínicos. Conclusão: Ao longo dos últimos 20 anos do sistema CEREC, muito se tem evoluído e certamente muito se vai continuar a evoluir. O resultado dessa evolução tem sido testado pelos variados estudos, mostrando que clinicamente é um sistema rápido e preciso. A medicina dentária eleva-se para outro nível com esta tecnologia e os profissionais da área ao perceberem isso vão certamente levar as consequências dessa evolução para o paciente, realizando tratamentos mais eficazes e rápidos sendo do ponto de vista clínico uma mais valia para todos. Introduction: The evolution of technology in all areas of activity has changed the way it addresses the challenges that are imposed today. In dentistry it has happened the same way as in health care in general, a huge resistance to new techniques and technologies, but what is certain is that the digital age is increasingly expanding and to getting over this resistance. CAD / CAM systems already form an integral part of the dental rehabilitation, mainly throughout dental laboratories, but also in the dentist’s office (with CEREC system) that places the CAD / CAM technology to the dentists and patients reach. Objectives: To determine, throughout a bibliographic review the evolution of the CEREC systems in past few years. This was intended to verify the clinical effectiveness of the system itself in the various materials it works with: for fixed prosthetic restorations and rehabilitations on impantes. Methods: In preparing this thesis a bibliographic review was performed in the period of 1994 to March de 2015. Databases were used as Pubmed (Medline), Elsevier, sceilo and googleacademic with the keywords "digital prosthetic dentistry" ; "Dental cad / cam" ;"Dental ceramics" ;"CEREC" ;"CEREC system" ;"CEREC materials." Results: In this review studies checked restorations made by the CEREC systems had good clinical behavior in the following various aspects: aesthetics, marginal fit, wear resistance and other clinical parameters. Conclusion: Over the last 20 years the CEREC system, much has developed and certainly much is going to keep evolving. The result of this evolution has been analised by various studies showing that clinically it is a very fast and precise system. Dentistry has been elevated to a whole new level with this technology and the professionals aswell, that being so, the consequences of this evolution will be led to the patient, the treatments will be faster and more effective, from the clinical point of view with an added value for everyone.

Abstract:

AbstractSuccessful implant dentistry mandates implants to be placed in an appropriate three-dimensional manner that supports the prosthesis adequately. Due to the resorption patterns of edentulous jaws, the ideal position of implants required varying amounts of bone augmentation. Commonly carried out bone-augmentation procedures are Guided Bone Regeneration, onlay bone grafting and sinus floor elevation. This chapter discusses the resorption pattern of edentulous jaws, the biology of alveolar bone of relevance to the maxillofacial surgeon, the biomaterials used for augmentation and the commonly carried out augmentation procedures.

Abstract:

The laboratory side of a digital dental workflow consists of heterogeneous software tools including digitization (scanning), modeling (CAD), production planning (CAM) and production. The heterogeneity can be structured in two dimensions: ‘various partial systems’, composing the dental product development system and ‘various vendors’, offering software solutions for these partial systems. As a result the value creation process lacks efficiency and different input/output data streams are still necessary. As a standard for the representation of geometric data the STL format has been established, whereas for additional information, such as organizational and administrative data, as well as requirements and design data, the XML (eXtensible Markup Language) format is considered appropriate. However, a variety of proprietary XML data formats have been developed by system vendors. Thus incompatibilities are a significant source for errors. Data flow structures as available today only allow unidirectional flow of information ‘downstream’. A new approach is based on a federative workflow data management. The basic concept is a unified XML scheme that represents data about all activities and states of dental objects created throughout the whole cycle of dental process. The new unified XML scheme provides a data structure, which can be adapted for the respective input/output data streams of all partial systems. The XML scheme represents a unified data scheme which allows both vertical (within a certain partial system class) and horizontal (along the digital dental workflow and independent of system vendor) data usage. Each dental system supplier only needs to create one input and output filter for the neutral XML interface. The system architecture is based on a web server to which a XML database server is connected. The XML database server manages project specific XML databases. Data can be made available through REST-, as well as through WebDAV-interface on LAN or WAN. With the help of XPath and XQuery required data can be extracted from the database. Redundant data input as well as incompatibility errors can be avoided by this approach. The innovative core is a unified workflow data format, in which a bidirectional data flow can be provided for both downstream and upstream, along the digital dental workflow.

Abstract:

The article presents the data of an original study on the improvement of orthopedic treatment of partial secondary adentia in patients with concomitant chronic pathology of the gastrointestinal tract by the method of removable plate prosthetics. For this purpose, a comparative analysis of three alternative to each other preparations of methyl acrylic polymer for the manufacture of bases of prostheses was made: 1) «GC», 2) «3M-Espe», 3) «Ftorax». A scientific assumption has been formulated that the choice of a specific polymer preparation (within the comparison base) will lead to a change in the number of complications developing during the operation of the prosthesis. In three independent groups of patients, using the compared preparations of methyl acrylic polymer, the relative number of complications was estimated. After the implementation of the study, it was found that the most positive results are shown by the polymer «GC», the least positive – by the polymer «Ftorax», the polymer «3M-Espe» occupies an «intermediate position». The results obtained have a high level of statistical significance, which makes it possible to recommend them for consideration for use in the practice of orthopedic dentistry.

Full text

Abstract:

Bruxism is a nonfunctional motor activity that is characterized by grinding and clenching of the teeth. It has been postulated that bruxism causes excessive occlusal load on the dental implant and its superstructures leading to biological and biomechanical complications. While many researchers suggest that grinding/clenching causes early implant complications and accelerated bone loss, others indicate that the long term effects are still unclear. The goal of this study is to analyze the effect of bruxism loading condition on the stress distribution of an implant supported overdenture (ISO) using finite element analysis (FEA) and compare the results with one of the most functionally efficient occlusion schemes in the clinical dentistry — lingualized occlusion. A high fidelity solid model of a mandibular denture encompassing lingual and buccal cusps, mesial and distal fossae supported by four implants and a connecting titanium prosthetic bar, resting on alveolar bone were modeled in SolidWorks 2013 following proper clinical guidelines and imported to ANSYS 15.0 for stress analysis. The results of the study demonstrate that the stress distribution in the implant prostheses and surrounding bone is significantly affected due to bruxism as compared to the lingualized loading. While the location of the maximum stress concentration was the same (neck of the posterior implants) for both loading conditions, there was an increase of approximately 115% von-Mises stress for bruxism loading condition as compared to the lingualized occlusion. The maximum principal stress in the cortical bone surpassed the ultimate tensile strength limit of the jaw bone implying possibility of bone resorption in the peri-implant area.

Abstract:

3D shape recognization technique is rapidly advancing from last decade in the fields of manufacturing, computer science, entertainment and medical technology. Due to the restriction of size and area of cavity, it’s challenging to develop such non-contact optical technologies for scanning. 3D digitization technology plays a vital role in the field of dentistry benefiting dentists and patients by eliminating long time procedures for making the prosthesis/abutments and results into ultimate comfort. In this paper, we have recounted a design of a prototype for a three-dimensional intra-oral scanner using the principle of fringe projection and active triangulation method. LED as a light source passed through the liquid crystal on silicon (LCoS) which radiates the light into three colors and strikes onto the collimating lens assembly and then passed through the optical deflectors. Once the light strikes the object through scanning window it is guided back through the flat reflectors and the fringe pattern on the object is stored into the gray encoding plate. With the help of camera all these images are stored. After the acquisition of images, firstly it will calculate the phase distribution using four-step phase shifting algorithm and unwrap the wrap phase which helps us in getting accurate images. Later, we get display of scanned oral cavity onto the computer screen. Phase-height mapping algorithm has been realized for the reconstruction of the 3D real time reconstruction of the scanned oral cavity which helps us in fast scanning with accurate data. A novel approach of LED as a light source and LCoS display for scattering light fragments into three different colors helps us to scan more effectively for registration of dental surfaces from the patient’s mouth more accurately. Apart from that, its sleek design helps to scan with less pain to the patient’s having low mouth opening. Experiment was performed on the prototype of denture and using this proposed method we have achieved the accuracy of 25μm and it took around 180 sec for the full arc scan of the lower oral cavity. The result of scanned data was checked using the CAD/CAM software for dentistry and compared with the prototype data of denture. Further this image can be used for making prosthesis/abutment directly into production using 3D printing machine or the milling machine. Thus, an abutment or prosthesis obtained with this method is of high quality and eliminates conventional long procedures which helps in reducing pain of patient’s and helps dentists to attain more patients in less time.

Abstract:

This paper presents the development of a 4-axis CNC milling machine for making dental restorations. The machine was developed to help spread knowledge about CAD/CAM to future professionals in healthcare area, including automation engineering. The CAD/CAM systems can be found in dental clinics and specialized laboratories with a high added value, as it brings reliability, precision, and speed to the prosthesis developed and, thereby, increasing the qualityof the nal product. With this high cost, not all dental professionals can have this type of technology. However, it is demonstrated the possibility of building these systems at a reduced cost and applying them to restorative dentistry. Therefore, this work results in instigating of the engineering education and training future professionals in mechatronics research with applications to the Odontology.

Abstract:

Rapid prototyping is an effective way to build prototypes. This process, now called AM (Additive Manufacturing), is suited to realize functional single part or for small batch production. Evolution of AM is now in the way of serial production. In the field of medical applications and more precisely dentistry, AM is a way of increasing numbers of elements produced compared to classic production by lost wax casting. To increase production quality, it is necessary to have a high monitoring and control of process and properties of production. In the case of AM using (DMLS: Direct Metal Laser Sintering), a lot of parameters can have an influence on the elements production quality such as powders quality, laser behavior or sintering time… The goal of this work is to study the serial production quality using a DMLS system (Phenix System PM100). This system is used in production of cobalt-chromium elements for dental applications. The study was done on a period of 6 months with recording results of almost 120 productions and was focused on a quantity of around 7000 dental elements produced. In a first part, number of elements per production, room temperature and hygrometry, powder reloading, maintenance, production stops and new operators are recorded. Material properties of some elements produced such as dimensional properties, density, porosity and crystallographic phases are monitored. Materials analysis has led to ensure the elements quality produced by the Phenix system and results are discussed in this work. In a second part, we focused on the production analysis with the recorded data. Analysis leads to define 2 ratios: production ratio RP defined as [Elements Number]/ [Productions Number] and the efficiency production PE defined as the ratio RP/[Stopped production number]. By calculating RP and PE values with collected data on the Phenix system, a PM 100 efficiency production modeling has been established. The PM 100 production modeling can help to understand that increasing the production ratio RP value leads to have efficiency production PE high variation. On another hand, collecting production parameters leads to increase production efficiency.
