DEVICE FOR PERFORMING A TRANSGINGIVAL IMPLANTATION

The invention relates to the field of medicine, in particular to orthopaedic stomatological devices for tooth implantation. The device for performing a transgingival implantation is in the form of a saddle-like structure comprising a support base and long and short support arms arranged at an identical angle to the base. Openings are formed in the long support arms, and one through-opening with a thread is formed in the short support arms, said openings being formed at an equal distance from the support base and from one another and being intended for screws formed with a pointed end on one side and a hexagon socket head on the other side. With the aid of the screws of the long support arm, the apparatus is fixed on the alveolar ridge. The saddle-like shape of the device is envisaged for fixing the device on the alveolar ridge. The screws are all of identical length. A bush with an internal thread is arranged in the centre of the support base, said bush being intended for connection to a mother cylinder having an inner diameter which corresponds to the outer diameter of the implant. The bush moves only in the direction of the support arms. A daughter cylinder having an inner diameter equal to the outer diameter of a drill for forming a recess in the bone underneath the implant is arranged in the mother cylinder. The movement of the daughter cylinder in the mother cylinder in the clockwise direction and along the vertical during drilling of the bone is limited with the aid of a "lock". The "lock" is produced with the aid of a point projection on the surface of the daughter cylinder and an L-shaped groove located in the inner surface of the mother cylinder. The device also comprises special extension arms intended for determining the position of the mother cylinder relative to the latter screws of the long support arm. L'invention se rapporte au domaine de la médecine et concerne notamment des dispositifs orthodontiques de stomatologie pour l'implantation de dents. Le dispositif permettant d'effectuer une implantation transgingivale possède une structure en forme de selle comprenant une base de support ainsi que des épaulements de support longs et courts qui sont disposés selon un même angle par rapport à la base. Des ouvertures sont formées dans les épaulements de support longs, tandis qu'une ouverture filetée traversante est formée dans les épaulements de support courts, lesquelles sont à distance égale de la base de support et l'une de l'autre et sont pré
