• Patients in need of an implant with a simultaneous GBR procedure.
• Presence of buccal bony dehiscence with a vertical defect height (VDH) ≥ 1 mm and ≤ 6 mm after implant placing.
• The tooth at the implant site must have been extracted or lost at least 8 weeks before the date of bone augmentation (volumetrically healed site).

Exclusion criteria

• Patients < 18 years.
• Currently pregnant or breastfeeding women.
• Major systemic diseases (e.g. recent myocardial infarction, cerebrovascular accident or valvular prosthesis surgery, a poorly stabilized diabetes mellitus, severe hypertension, severe peripheral artery occlusive disease, malignancies, autoimmune diseases, or kidney diseases, untreated or uncontrolled periodontal disease, uncontrolled drug or alcohol abuse, uncontrolled psychiatric disorders).

• Previous or current use of antiresorptive drugs (ARDs) (e.g. bisphosphonates, selective estrogen receptor modulators (SERMs), denosumab, hormone replacement therapy and calcitonin).
• Previous oral / maxillofacial radiotherapy.
• Heavy smoker (>10 cigarettes/day). In the case of vapors with nicotine, the use of >300 puff vapors (equivalent to 10 cigarettes/day) are not allowed.
• Health conditions, which do not permit the surgical treatment.
• Use of the Investigational Device / Comparator in infected areas.
• Known foreign body sensitivity to implant materials.
• Simultaneous participation in another interventional clinical trial (drugs or medical devices studies) if it could impact the result of the study.
