RESUMO

Objetivo: comparar la adaptación marginal In Vitro de incrustaciones MOD con terminación en esmalte fabricadas con IPS e.max CAD (Computer Asisted Desing) y fabricadas en oro tipo III. Materiales y métodos: En este estudio experimental exploratorio se uso una muestra no probabilística de 15 premolares sanos por cada uno de los dos grupos; IPS e.max CAD y oro tipo III.A todos los premolares se les realizó cavidades MOD estandarizadas para los 2 grupos. Los dientes preparados fueron asignados aleatoriamente a cada grupo. Las incrustaciones del grupo IPS e.max CAD fueron elaboradas con el sistema CEREC 3 y las incrustaciones en oro fueron elaboradas por los investigadores. Se tomaron estereo microfotografías de todas las muestras sobre papel milimetrado, y las imágenes fueron analizadas mediante el programa ImageTool. Se tomaron tres medidas adaptación marginal en el área proximal mesial o distal de cada muestra, que fueron promediadas y reportadas en micras. Los datos fueron analizados mediante ANOVA y Test de Mann-Whitney. Resultados: el 98% del total de las incrustaciones en oro y el 47% del total de las incrustaciones de IPS e.max CAD presentaron una adaptación marginal < a 120 micras. El promedio de desadaptación marginal del grupo IPS e.max CAD fue 122.8 μ + 44.1, mientras que para el grupo oro fue de 75.3 μ+42,6 encontrándose diferencias estadísticamente significativas entre los dos. Conclusiones: El oro reporta mejor adaptación marginal en restauraciones inlays MOD que los sistemas maquinados como el sistema IPS e.max CAD.


Objective: To compare In Vitro, the marginal adaptation of MOD fillings with an enamel finish manufactured with IPS e.max CAD (Computer Assisted Design) and those manufactured with gold type III. Materials and methods: In this exploratory experimental study, a non-probabilistic sample of 15 healthy premolars for each of the two groups (IPS e.max CAD and gold type III) was used. Standardized MOD cavities were made in all the premolars for both groups. The prepared teeth were randomly assigned to each group. The IPS e.max CAD fillings were made using the CEREC 3 system and the gold fillings were made by the researchers. Stereo microphotographs of all the samples were taken on millimeter paper and the images were analyzed using the Image Tool software. Three marginal adaptation measurements in the mesial proximal or distal area were taken for every sample; they were averaged and reported in microns. The data was analyzed using ANOVA and the Mann-Whitney test. Results: 98% of all the gold fillings and 47% of all the IPS e.max CAD fillings showed a marginal adaptation of less than or equal to 120 microns. The marginal unfitness average for the IPD e.max CAD group was 122.8 + 44.1 μm, and for the gold fillings group it was 75.3 + 42.6 μm. There was a statistically significant differences between the groups. Conclusions: Gold reports a better marginal adaptation for inlay MOD fillings than manufactured systems like IPS e.max CAD system.
