简要总结
The goal of this observational study is to measure in real practice the performance and safety of RTR+Membrane, a synthetic dental membrane for guided tissue regeneration in periodontal or dental implant surgery. The main question it aims to answer is to measure the post-operative wound healing several months after surgery. Participants will be followed after their dental surgery via clinical examination and radiological and photos images.
详细描述
Participants are any adult patients with one of the 3 following dental treatments to be done with RTR+Membrane: * post-extraction socket preservation, * alveolar ridge augmentation, * Guided Tissue Regeneration (GTR) during immediate implant placement. Since it is a real-life evidence study in current practice, patients will be followed at their surgery and their follow-ups. Below are listed visits and type of data collected. * V1 - Surgery: Demography, Medical history and concomitant treatments, Clinical/technical information (tooth extraction, surgery, membrane and grafting materials use), Clinical Exam, Photography, X-rays or Cone Beam Computed Tomography (CBCT) * V2 - Early follow-up (including suture removal, if needed): Clinical Exam, Questionnaire, Photography * V2bis - Early follow-up: Clinical Exam, Photography * V3 - Late follow-up: Clinical Exam, Photography, X-rays or CBCT, Questionnaire

结局指标
主要结局
Post-operative wound healing measured by the Early Wound-Healing Index
时间窗: up to 6 months
For all groups The Early Wound-Healing Index (EHI) has the following best to worst scoring: (EHI) 1: complete flap closure without fibrin line in the interproximal area. (EHI) 2: complete flap closure with fine fibrin line in the interproximal area. (EHI) 3: complete flap closure with fibrin clot in the interproximal area. (EHI) 4: incomplete flap closure with partial necrosis of the interproximal tissue. (EHI) 5: incomplete flap closure with complete necrosis of the interproximal tissue. The EHI is evaluated at the Visit 3 (late post-surgery follow-up) for the primary outcome measure.

- Post-operative clinical exam(up to 6 months)
- Post-operative wound healing measured by Early Wound Healing Score(up to 14 days)
- Oral Health-Related Quality of Life measured by the Oral Health Impact Profile (OHIP-5 items)(up to 6 months)
- Radiological measurements on CBCT(up to 6 months)
- Radiological measurements on retro-alveolar radios(up to 4 months)
