A template (30, 38) is used to form holes for implants in bone (28, 34), preferably jaw bone, without any negative effect from the existing resiliency in the flesh/gum surrounding the bone. The template is adapted to the shape or shapes of the bone and of the gum and has guide holes for a hole forming unit (drill) (11). The template is designed for application to the bone with the gum lying in between, and the template is arranged to be able to cooperate with two or more anchoring elements (20, 21, 22, 23) intended to extend through the gum and into and preferably through substantial parts of the whole bone. The hole-forming unit is in this way arranged to penetrate through the gum during hole formation in the bone. The invention affords advantages in that the gum does not need to be folded back to expose the bone/jaw bone, which fact considerably shortens the fitting time for dental bridge application and spares the patient from a more extensive surgical intervention, which exposure of the bone below the gum entails.
