Resumen
Hoy en dĆa la odontologĆa adhesiva se ha desarrollado rĆ”pidamente, con lo que podemos encontrar numerosos materiales de cementaciĆ³n. Por esta razĆ³n el poste de fibra ha surgido como una excelente alternativa en prĆ³tesis fija, siendo una de las causas mĆ”s frecuente de fracaso la decementaciĆ³n. Esta puede ser causada principalmente por una falla en la adhesiĆ³n entre las interfases, dentina- cemento y poste.
Objetivo: El objetivo fue evaluar la resistencia a la tracciĆ³n de pernos de fibra de vidrio cementados con MultilinkĀ® Primer A/B versus Relyxā¢ U 100Ā®.en piezas tratadas endodonticamente selladas con cementos de resina epĆ³xica.
MetodologĆa: Se realizaron 50 muestras de piezas naturales a las cuales se les realizo tratamiento endodontico y fueron sellados con TopsealĀ® Luego se dividieron las muestras aleatoriamente en dos grupos, cada grupo de 25 muestras, se desobturaron y se cementaron los postes de fibra de vidrio con 10mm longitud Un grupo utilizĆ³ cemento MultilinkĀ® Primer A/B y el otro grupo cemento Relyxā¢ U100Ā®. Posteriormente fueron sometidos a tracciĆ³n luego de 48 horas, con la maquina Tinius Olsen modelo H5K-5. Los resultados fueron analizados con el soffwer Systat U.13 aplicando el test Shapiro Wilck y Students.
Resultados: Se encontrĆ³ diferencias estadĆsticamente significativas entre los cementos MultilinkĀ® Primer A/8 y Relyxā¢ U100Ā® (p =0.000) dado por el Test de Student. Los valores promedios encontrados son MultilinkĀ® Primer A/8 7 Mpa y Relyxā¢ U100Ā® 4 Mpa.
Conclusiones: El grupo MultilinkĀ® Primer NB mostraron mayores valores a la tracciĆ³n con respecto al grupo Relyxā¢ U100 existiendo diferencias significativas.
Nowadays adhesive odontology has developed itself quickly. We can find a number of adhesive materials. For that reason, fiberglass pole has emerged as an excellent choice of fixed prosthesis, being it one of the main causes of debonding. The former can be caused mainly by a failure of adhesion between the interfaces, dentine, cement and fiberglass pole. Objectives: The objective of this study was to evaluate the tensile strength of glass fiber fixation screws cemented with Multilink Ā® Primer A / B versus U RelyxTM 100 Ā®. on samples endodontically sealed with epoxy cement. Methodology: 50 natural samples were taken in which endodontic treatment was performed and then sailed with TopsealĀ®. Next, the samples were divided randomly into two groups, each group of 25 samples, and they were unblocked and then the fiberglass poles were cemented, all at 10mm. One group u sed cement Multilink Ā® Primer A/ B and the other group RelyxTM U100 Ā® They were subjected to traction after 48 hours with a Tinius Olsen machine H5K-5 modelĀ®. The results were analyzed with Systat U.13 software, using Shapiro Wilck and Students tests. Results: Statistically significant differences were found between Multilink Ā® Primer cements A/ B and U100 RelyxTM Ā® (p = 0.000) given by the Student Test. The average values found are Multilink Ā® Primer A/ B 7 MPa, and for RelyxTM Ā® U100, 4 MPa. the MultilinkĀ® Primer A/B group showed larger values of tensile strength in comparison of RelyxTM U100 group, existing considerable differences.
