On the left side, a vertical bone septum (visible on Fig. 1) requires two separate lateral approaches. Insertion of interim implants The planned minimally invasive flapless procedure for implant insertion requires a unique fixation for the preparation of radiological materials. The fixation is facilitated by temporary implants in a suitable position. In order to ensure accurate transferability, the fixation must be performed under radiological control in the identical position as the one of the implantation.

Coverage of the lateral window with a resorbable collagen membrane to avoid displacement of the bone substitute material.
