The upper model is always mounted with the incisal pin at zero. When mounting the lower to the upper using an ICP interocclussl record, the incisal pin should remain at zero. If mounting using a Centric Relation interocclusal record, the amount of opening in the mouth should be replicated on the articulator by increasing the incisal pin height by the same amount prior to mounting the lower model.

Very useful video
What about the incisal pin, is it on zero? Or do u increase it ? How much? Before mounting the upper or just lower? Do use leaf gauge?
