NCT07058506
Neurinnov, in collaboration with the CBV USSAP center and the CAMIN INRIA team, has conducted clinical investigations using various control interfaces, including EMG, IMU, contact sensors, and voice commands, to operate a motor neuroprosthesis. This neuroprosthesis is based on neural electrical stimulation, enabling the activation of multiples muscles via a single electrode. The clinical investigations have successfully demonstrated the feasibility of achieving grasping movements induced by neural electrical stimulation, which are controlled by the participant through external interfaces. These external interfaces were based on existing technologies but were only suitable for research purposes due to their lack of portability. The current investigation aims to validate fully portable interfaces designed by Neurinnov, which are intended to be integral components of a future medical device that includes an implanted stimulator and its neural electrodes. The study's goal is to demonstrate that these interfaces can be used by participants with sufficient success rate (clinical performance) to support daily use. Our main hypothesis is that the participants can effectively use at least two of the six control interfaces presented to them to detect their intention to perform a motor action within a software environment under constant conditions. These interfaces include voice commands, inertial measurement unit (IMU) sensors, surface electromyography (EMG) sensors, switch, joystick, and earswitch.

From an exclusively periodontal point of view, the extraction of third molars (3M) or wisdom teeth is relatively frequently recommended, either because they show reduced bone support or to avoid periodontal damage to the supporting bone of the adjacent second molar (2M). There are anatomical conditions that make plaque control difficult for the patient, and it is common to find periodontal pockets with significantly increased depths on the distal side of second molars that are or have been closely associated with an impacted third molar. Among the periodontal considerations regarding impacted third molars, two aspects have traditionally been included: 1)The periodontal damage that certain impactions can cause to the periodontal health of the second molar, and 2) the periodontal sequelae or complications that the extraction of a wisdom tooth may leave on the distal surface of that second molar. Various therapeutic approaches have been described in the literature to prevent periodontal damage following the surgical intervention involved in the extraction of a fully or partially impacted wisdom tooth. These include scaling of the distal surface of the 2M after extraction, modifications in the surgical technique - such as flap design or suturing method - and various regenerative techniques. Within this context, the clinical research in which we invite the patients to participate will be developed. We will study the changes in bone levels on the posterior part of the second molar that is in contact with or close to the third molar, as well as the health of the soft tissues, after performing a conventional extraction protocol of the impacted lower third molar. This protocol includes the placement of a regenerative material of porcine origin (test procedure; enamel matrix derivatives) and will be compared to extraction without such material - and therefore without any attempt at periodontal regeneration (standard procedure). The patients will be closely followed up to one year after the surgical performance. This follow-up will be performed clinically and radiographically.
