O objetivo foi avaliar a alteração dimensional dos moldes de silicona por condensação imediatamente, 30min, 1h e 7 dias após a moldagem, com o auxílio da máquina de medição tridimensional por coordenadas. Os grupos foram divididos em: G1: Speedex Putty/Speedex Light Body (Coltene/Vigodent AS Indústria e Comércio), G2: Optosil P Plus/Xantopren L Blue (Heraeus Kulzer GmbH), G3: Zetaplus Putty/Oranwash L (Zhermack SpA) e G4: Precise SX (Dentsply Indústria e Comércio Ltda). Para a obtenção das 80 medições dos 4 materiais (n=20), foi usado um dispositivo composto por uma moldeira perfurada e uma outra parte com 3 edentações pré-estabelecidas. Para a avaliação dimensional, a máquina Crysta-Plus M 574 (Mitutoyo) realizou cada medida 3 vezes nos tempos estabelecidos e obteve-se a média aritmética. A média final das 4 distâncias I, II, III e IV do dispositivo edentado foi novamente aplicada. A análise estatística foi realizada com o teste de Kolmogorov-Smirnov que rejeitou a hipótese nula de distribuição assimétrica. Posteriormente, foi feita a ANOVA para comparar os 4 materiais simultaneamente e o teste paramétrico t de Student para comparar os materiais 2 a 2. O nível de significância global foi de p≤0,05. A maior contração linear foi observada na Speedex, mas não foi significante (p=0,08). A Zetaplus Putty/Oranwash L parece ser a mais estável (p=0,99), mas não foi significante. Não houve diferença estatisticamente significante entre nenhuma silicona por condensação quando comparadas simultaneamente nos 4 tempos ou quando comparadas 2 a 2, à exceção, Precise SX e a Speedex (p=0,05) no tempo T3. Todas as siliconas por condensação testadas apresentam alteração dimensional clinicamente aceitável e podem ser vazadas imediatamente, 30min, 1h e 7 dias após a moldagem.
The purpose was to evaluate the dimensional changes of condensation silicone impressions by immediately, 30min, 1h and 7 days after impression, with the help of threedimensional measuring coordinate machine. The groups were divided in: G1: Speedex Putty/Speedex Light Body (Coltène/Vigodent S/A Ind and Com), G2: Optosil P Plus/Xantopren L Blue (Heraeus Kulzer GmbH), G3: Zetaplus Putty/Oranwash L (Zhermack SpA) and G4: Precise SX (Dentsply Ind and Com Ltda). To obtain 80 measurements of 4 material (n=20) was used a device consisting of a perforated tray and one another part with 3 pre-established indentations. For dimensional evaluation, the Crysta-Plus M574 machine (Mitutoyo) held each measurement 3 times at the established times and obtained the arithmetic mean. The final average of the 4 distances of I, II, III and IV the edentulous device was again applied. Statistical analysis was performed using the Kolmogorov-Smirnov test to reject the null hypothesis of asymmetric distribution. Subsequently, ANOVA was performed to compare the four materials simultaneously and Student's t parametric test to compare the 2 by 2 materials. The overall significance level of p≤0,05. The higher linear contraction was observed in Speedex, but was not significant (p=0,08). The Zetaplus Putty/Oranwash L seems to be more stable (p=0,99) but was not significant. There was no significant difference between any silicone condensation compared simultaneously in 4 times or compared 2 by 2, except, Precise SX and Speedex (p=0,05) in T3 time. All tested condensation silicones exhibit clinically acceptable dimensional change and can be leaked immediately, 30min, 1h and 7 days after impression.

O objetivo deste estudo foi mensurar a alteração dimensional de uma silicona por condensação através de um paquímetro digital (Mitutuyo), de um estéreo microscópio (Olympus) e de uma máquina de medição tridimensional por coordenadas (Mitutuyo). Foram realizadas 4 moldagens através de um dispositivo específico com a silicona por condensação pesada e leve Speedex (Coltene/Vigodent). Em cada um dos 4 moldes 4 distâncias foram mensuradas pelos 3 instrumentos, em 4 tempos distintos: no momento da remoção do molde e após 30min, 1h e 7 dias. As médias das mensurações foram submetidas ao teste estatístico Kruskal-Wallis com nível de significância de 5%. Os resultados mostraram diferenças significantes entre as alterações dimensionais verificadas por cada um dos instrumentos de medição, as mensurações realizadas pelo paquímetro digital e pela máquina de medição tridimensional por coordenadas apresentaram alterações dimensionais significantes nos 4 tempos testados, enquanto as pelo estéreo microscópio não apresentaram diferença significante nos 4 tempos. Concluiu-se que as alterações dimensionais verificadas nos moldes da silicona por condensação testada obtidas através de cada instrumento de medição utilizado nesta pesquisa foram diferentes entre si, evidenciando que os diferentes métodos de medição utilizados podem fornecer resultados distintos, e consequentemente, indicações equivocadas.
The aim of this study was to measure the dimensional changes of a silicone condensation using a digital paquimeter (Mitutuyo), an estereomicroscope (Olympus) and a three-dimensional coordinate measuring machine (Mitutuyo). Were made 4 impressions trhough a specif device using the putty and light silicone condensation Speedex (Coltene/Vigodent). Four distances were measured at each impression through the 3 instruments at 4 different times: in the moment of removal of the die and after 30min, 1h e 7 days. The avarage of the measurements were subimitted to the statistical test Kruskal-Wallis with level of significance of 5%. The results shows significant diferences between the dimensional changes verified by each one of the measuring instruments, the measurements through the digital paquimeter and the measurements trhough the three-dimensional coordinate measuring machine showed significant dimensional changes in the 4 tested times, while the measurements through the estereomicroscope did not show significant difference in the 4 tested times. It concludes that the dimensional changes verified in the tested silicone condensation by each measurement instrument used in this study were diferente, indicating that the different measuring methods used can provide wrong results, and consequently, wrong indications.

Resumo: Baseado no entendimento incompleto de como o conteúdo de partículas de carga influencia nas propriedades mecânicas dos materiais de moldagem este estudo avaliou quantitativa e qualitativamente o conteúdo de partículas de carga inorgânicas presente em cinco marcas comerciais de alginatos (Jeltrate; Jeltrate Plus, Jeltrate Chromatic Ortho, Hydrogum e Ezact Krom) e nove marcas comerciais de siliconas de adição e/ou condensação nas consistências massa e/ou fluida (Clonage, Elite HD+ Light Body, Express Light Body, Flexitime, Optosil P Confort/Xantopren VL Plus, Oranwash L, Reprosil A+, Silon 2 APS e Virtual Extra Light Body). Foram realizados testes para determinar recuperação elástica e deformação sob compressão dos alginatos e dos elastômeros e estabelecer, dessa forma, uma correlação entre os resultados para partículas de carga e os testes mecânicos. O conteúdo volumétrico das partículas de carga foi determinado pesando-se as amostras submersas em água antes e após a queima das mesmas durante 3h a 450°C (alginatos) e a 600°C (siliconas). Quantidades determinadas de materiais não polimerizados foram lavadas em acetona e clorofórmio e recobertas com ouro para avaliação da morfologia e tamanho das partículas em M.E.V. A composição foi determinada por EDX. A recuperação elástica e a deformação sob compressão foram determinadas de acordo as especificações ? 1563 (alginatos) e 4823 (elastômeros) da ISO. O alginatos Jeltrate e Jeltrate Plus apresentaram os maiores valores médios para quantidade volumétrica de partículas de carga (%) enquanto o material Hydrogum apresentou os menores valores. A silicone de adição Flexitime Easy Putty apresentou os maiores valores de quantidade volumétrica de partículas, enquanto que a silicone de condensação Xantopren VL Plus apresentou os menores. As partículas de carga dos alginatos apresentaram-se, de forma geral, como objetos esféricos e com perfurações. O material Hydrogum apresentou forma de bastões cilíndricos e perfurados. As siliconas apresentaram morfologias variadas ¿ partículas trituradas, esféricas, esferóides, bastões cilíndricos perfurados e bastões misturados a partículas usinadas. O alginato Ezact Krom apresentou os maiores valores médios de tamanho de partícula, enquanto que o alginato Hydrogum as menores. A silicone de condensação Clonage massa apresentou os maiores valores médios de tamanho de partícula, enquanto a silicone de adição Elite HD os menores. A análise da composição das partículas apresentou o silício como o elemento em maior quantidade. Com relação aos resultados de recuperação elástica, o alginato Ezact Krom e as siliconas Reprosil A+ massa e Flexitime fluida apresentaram os maiores valores de recuperação elástica, enquanto o alginato Jeltrate Plus e as siliconas Optosil P Confort e Clonage fluida apresentaram os menores. Os resultados de deformação sob compressão foram maiores para o alginato Jeltrate Plus e para as siliconas Silon 2 APS massa e fluida. Os menores resultados foram apresentados pelo alginato Ezact Krom e as siliconas Reprosil A+ massa e Xantopren VL Plus. Todos os materiais estão em conformidade com a norma ISO ?1563, mas nem todos estão em relação à norma ?4823
Abstract: Based on the incomplete understanding on how filler features influence the properties of elastomeric impression materials, the purpose of this study was to determine the inorganic filler fraction and size of five commercially available alginates (Jeltrate; Jeltrate Plus, Jeltrate Chromatic Ortho, Hydrogum e Ezact Krom) and nine addition/condensation silicones using the putty/light consistence (Clonage, Elite HD+ Light Body, Express Light Body, Flexitime, Optosil P Confort/Xantopren VL Plus, Oranwash L, Reprosil A+, Silon 2 APS e Virtual Extra Light Body). A SEM/EDX analysis was done to qualitatively characterize the materials. Soon afterwards elastic recovery and strain in compression of the alginates and some the silicones was carried. The inorganic particles volumetric fractions were accessed by weighing a previously determined mass of each material in water before and after burning samples for 3 hours at 450ºC (alginates) and 600ºC (silicones). Unsettled materials were soaked in acetone and chloroform and sputter-coated with gold for SEM evaluation of fillers¿ morphology and size. The filler composition was determined by EDX. Elastic recovery and strain in compression tests were conducted according to ISO specification number 1563 and 4823. Jeltrate and Jeltrate Plus presented the highest mean values of percentage content of inorganic particles in volume, while Jeltrate Chromatic Ortho presented the lowest values. Flexitime Easy Putty was the silicone with the highest mean value, while Xantopren VL Plus had the lowest value. The alginate fillers presented a circular appearance with helical form and various perforations. Hydrogum fillers looked like cylindrical, perforated sticks. SEM pictures of the silicone inorganic particles showed numerous morphologies ¿ lathe-cut, spherical, spherical-like, sticks, and sticks mixed to lathe-cut powder. Ezact Krom was the alginate with the highest values for diameter size, while Hydrogum had the lowest. Clonage Putty showed the highest values, while Elite HD+ Light Body presented the lowest values. The component in higher concentration in the materials is silicon. The alginate Ezact Krom, and the addition cure silicones Reprosil A+ putty and Flexitime Correct Flow had the highest mean values of elastic recovery, while the alginate Jeltrate Plus and the condensation cured silicones Optosil P Confort and Clonage Putty presented the lowest values. Strain in compression test showed the alginate Jeltrate Plus and the condensation cured silicones Silon 2APS Putty and Fluid as the materials with the highest values. The alginate Ezact Krom and the silicones Reprosil A+ Putty and Xantopren VL Plus had lowest values. All materials are in conformity with the requirements of ISO specification number 1563, but not all materials are in conformity with the requirements of ISO specification number 4823

Full textBackground: VST-50 (a room temperature-vulcanizing silicone (RTV) by Factor II Inc.) has long been proposed as a potential alternative material for MDX4-4210, another RTV by Dow Corning Corp. and the current material of choice for maxillofacial prosthesis. Though VST-50 has similar chemistry and flexibility as MDX4-4210, its mechanical properties is still too low for it to be used in the clinic. An improvement in the mechanical property of VST-50 is a critical step to bring the material to clinical application. Objective: To investigate the effect of AEROSIL® R 812S (colloid silica) addition on the mechanical properties of VST-50 and compared to that of MDX4-4210. Methods: The VST-50 was mixed with AEROSIL® R 812S at 2 or 4 parts per hundred parts of rubber. That material was mixed with the catalyst under vacuum. The mixture was poured onto a machined plastic mold to produce a silicone sheet 3.0 ± 0.2 mm thick. All samples were prepared by manufacturer recommended method. Testing samples were prepared and tested following ISO 37 for tensile strength, ASTM D624 for tear strength and ASTM D2240 for shore A hardness test. One way ANOVA was used to compare the groups (Alpha=0.05). Result: Significant differences (P<0.001) were found between MDX4-4210 and modified VST-50 groups. The mean value of tensile strength, tear strength and hardness of VST-50 (4phr colloid silica) were 7.43(MPa), 34.82(N/mm) and 40.4 respectively, compared to MDX4-4210 were 3.67(MPa), 5.48(N/mm) and 31.5, respectively. Conclusion: Modified VST-50 with 4phr silica revealed improved mechanical properties to use as a maxillofacial prosthetic silicone elastomer.

Full textFabrications of desirable fixed or removable dental prostheses depend upon accurate casts or dies. Recently, the most frequently used impression materials have been polyether (PE) and polyvinyl siloxane (PVS). However, both have their limitations: PVS is inherently hydrophobic, and PE is rigid. In order to take advantage of the desirable qualities of both PVS and PE impression materials, a new generation of impression material is being developed called vinyl polyether silicone (VPES, GC). The purpose of the present study was to compare the properties of hydrophilic PVS, PE, and VPES in regard to surface detail reproduction, contact angle, and tear strength. The hypotheses to be tested were: 1) VPES will show a significant superiority insurface detail reproduction compared with PVS and PE impression materials; 2) VPES will show a significant superiority in wettability compared with PVS and PE impression materials; 3) VPES will show a significant superiority in tear strength compared with PVS and PE impression materials. In order to test the surface detail reproduction, impressions were made of stainless steel dies with a parallel series of 15 different width lines on the surface and tested under dry and moist conditions. The wettability was assessed by contact angles of saturated CaSO4 aqueous solution drops on flat impression surfaces. A trouser tear test was employed to test the tear strength. The trouser-shaped specimens were prepared and tested in the Instron Universal Testing Machine. The data were analyzed by one-way ANOVA and Pearson‘s Chi square, (p < 0.05). All the materials showed better detail reproduction under the dry conditions than the moist conditions. There were no differences between the three materials in detail reproduction when impressing under either moist conditions or dry conditions. All the materials showed good wettability in the contact angle test. PVS rendered a contact angle as low as 34.19º. The contact angle of VPES was 44.84º, which was lower than 54.76º for PE. In the tear strength test, PE showed nearly two time higher tear strength than the other two impression materials. VPES showed slightly lower tear strength than PVS. The tear strength of the three materials tested in increasing order was VPES, PVS, PE. VPES showed comparable detail reproduction to PVS and PE and better wettability than PE, but showed the lowest tear strength compared with PE and PVS.
