The goal of this retrospective PMCF study is to assess safety and performance of creos xenoprotect in all indications functioning as dental barrier membrane. The primary endpoint of the study is the occurrence of major complications during 6 months after creos xenoprotect placement whereas the hypothesis is that these major complications occur in less than 5% within this timeframe. This is a retrospective, multicenter clinical investigation with consecutive cases. Data will be collected on consecutive data cases from patient files, given that these patients were treated within a defined indication with creos xenoprotect in the past. Patients participating in this study do not have any obligations or need to come back for any intervention. A total of 11 centers are planned to be included. Sample size is n=200 patients and is distributed equally in four indication groups: Group 1: Ridge augmentation (vertical and horizontal) Group 2: Alveolar ridge preservation Group 3: Sinus floor augmentation Group 4: Augmentation around implant or teeth
