Later on, bleeding points were recorded, for this purpose the acetate provided by the Prosthesis Department was used as a guide, from second left upper premolar to second right upper premolar, on its vestibular face, so as to limit and trace the incision zone. For central teeth, the zenith direction was taken into account.
Posteriormente, se marcaron puntos sangrantes tomando como guía el acetato proporcionado por el Departamento de Prótesis, desde segundo premolar superior izquierdo al segundo premolar superior derecho por su cara vestibular, para delimitar y delinear la zona de incisión, tomando en cuenta la dirección del zenit de los dientes centrales.
