The invention relates to the field of medicine, and more particularly to dentistry, and is intended for use during tooth splinting in order to isolate gums affected by chronic generalized or localized periodontitis. The condition of the tissue of the periodontium and the degree of mobility of the teeth are determined. A diagnosis is made on the basis of clinical and X-ray examinations. Anaesthesia is performed, a professional oral hygiene procedure is carried out, and anti-inflammatory treatment and splinting are performed. Prior to splinting, the dental pulp is removed. To protect the gums from injury during splinting, a gum isolation method is used. A silicone impression compound consisting of two components is mixed to produce a homogeneous paste which is shaped into a rectangular block and left to solidify. Next, the width of the interdental space is measured using a micrometer and the measurement data is transferred to the silicone block. Then, billets are cut in the shape of wedges of the required size and are introduced into the interdental space between the patient's teeth. The teeth are splinted, whereupon the wedges are removed from the interdental spaces using a probe or tweezers without injuring the gums. The method makes it possible to secure the teeth and maintain the natural configuration of the interdental space during splinting.L'invention concerne le domaine de la médecine et notamment le domaine de la stomatologie et sert à l'application de la gouttière sur les dents pour l'isolation d'une gencive en cas de parodontite dans une phase chronique généralisée ou localisée. On détermine l'état des tissus du parodonte, le degré de mobilité des dents. On effectue le diagnostic sur la base d'un examen clinique et radiologique. On effectue l'anesthésie, le nettoyage hygiénique professionnelle de la cavité buccale, une thérapie anti-inflammatoire, une pose de gouttière, un dépulpage des dents. Avant de poser la gouttière on effectue un dépulpage des dents.
