| Defect fill | The primary outcome measure will be the change of "bone levels"(defect fill) over 2 years starting 1 year after surgical Intervention as assessed from intra-oral radiographs. In particular, the distances between the most apical implant to bone contact level and a characteristic reference point being the same for all sets of radiographs will be measured. The distance equal to three implant threads (known for the implant system) will be measured with a specific Software. The deeper bone level at baseline will be considered | 2 years after the start of the study |
