- Primary Outcome Measures
Name Time Method Primary endpoint is the safety of Collagen Matrix 10808 in the indication of single tooth gingival recession coverage. <br><br>Safety will be assessed based on soft tissue wound healing events that could be considered related to the device as listed below. <br>-Wound closure<br>-Inflammation of the tissues in the surgical area<br>-Flap necrosis<br>-Dehiscences <br>-Swelling of the soft tissues around surgical area<br>-Bleeding of the wound<br>-Presence of abscess/pus/fistula<br>-Sensibility disorders<br>-Any other reaction of the soft tissue in the area of the treatment<br><br>All Parameters will be assessed from Visit 3 onwards (Day 1, Day 3, Day 7, Day 14, Day 30, Day 90, Day 180).
- Secondary Outcome Measures
Name Time Method Safety <br>• Assessment of AEs<br>• Daily Ibuprofen consumption between day 0 and day 7<br>• Evaluation of pain using a VAS score at day 1, 3 and 7<br><br><br>Usability <br>• The appropriate surgical procedure and clinical handling will be assessed and defined by the evaluation of a standardized questionnaire completed by the surgeon. <br><br>Performance <br>• Mean root coverage (day 0, 90, 180)<br>• Recession width (day 0, 90, 180) <br>• Percentage of complete root coverage (day 0, 180)<br>• Thickness of soft tissue over the root measured by transmucosal needle probing (day 0, 180)<br>• Thickness of soft tissue over the root measured by Ultrasonic device (PIROP) (day 0, 14, 30, 90, 180)<br>• Periodontal tissue health status: KT width, PD, CAL, BOP, PI (day 0, 180) <br>• Evaluation of the esthetic appearance by the investigator (day 180)<br>
