Periodontal considerations of restorative procedures

Influence of margin design on the fit of high-precious alloy restorations in patients

“…1,2 Although it is generally accepted that the marginal errors should be minimized, very little information is available, in the real sense of evidence-based medicine, with regard to the relationship between marginal inaccuracy and longevity of the restoration. The geometry of the crown margin was the subject of many debates several years ago but this topic has faded out of the focus of interest in the current scientific discussion.…”

Effect of Storage Solution on Surface Roughness of Provisional Crown and Fixed Partial Denture Materials

“…These materials must meet esthetic, mechanical, and biologic requirements; a key requirement is the maintenance of periodontal health 1,2 . Since provisional restorations have been described as contributors to gingival inflammation and recession, 3‐5 suggestions have been made to ensure soft tissue health. To promote optimal periodontal health, the provisional crown should demonstrate good marginal fit, proper contour, and smooth surface topography 1 .…”

Profundidad del surco gingival en dientes primarios restaurados con coronas de acero cromo

“…Palomo y Peden en 1976, señalaron que las coronas con extensión subgingivales (largas) producen mayor inflamación gingival que aquellas ajustadas por encima del margen gingival. 29 El contorno inadecuado de los márgenes y los residuos de cemento en contacto con el surco gingival puede ocasionar una inflamación local del surco al tiempo que favorece la acumulación de placa bacteriana 30 .…”
