Measurement of the Performance and Safety of RTR+Membrane in Guided Tissue Regeneration (GTR) in Dental Surgical Procedures

To join this study, you need to be an adult patient (between 18 and 89 years old) who is already planning to have one of three specific dental treatments using the RTR+Membrane. These treatments include preserving the empty socket after a tooth is removed, adding bone to your jaw (called alveolar ridge augmentation), or having a dental implant placed immediately after a tooth extraction where bone regeneration is also needed.

You should also be part of a social security system and must give your written permission to take part by signing an informed consent form. The study is open to both men and women.

There are some reasons why you might not be able to join. For example, if you are pregnant or breastfeeding, have an active infection in the area being treated, or if you need several complex dental treatments in different areas at the same time. Heavy smokers (more than 10 cigarettes a day) are also not suitable, nor are people receiving certain medications like long-term steroids or some cancer treatments. If you have poorly controlled conditions like diabetes, certain autoimmune diseases, or chronic infections at the surgical site, you would also not be able to participate. Finally, people who might have difficulty understanding or completing questionnaires on their own are also excluded.

If you take part in this study, you'll be followed throughout your regular dental treatment and follow-up appointments. There will be several visits where information is collected. At your surgery appointment (V1), the dental team will record some general information about you, your medical history, and details about your dental treatment, including the use of the membrane. They'll also perform a check-up, take photographs, and likely X-rays or a more detailed 3D scan (CBCT).

You'll have early follow-up visits (V2 and V2bis), which might include removing stitches if needed. During these visits, there will be a clinical check-up, more photographs, and you might be asked to complete a questionnaire. Finally, you'll have a late follow-up visit (V3) where you'll have another check-up, photographs, X-rays or CBCT scans, and another questionnaire. You will continue to follow your dentist's usual instructions regarding your medication and aftercare.
