Abstract: The invention relates to a dental implantology device combining a specific drill (21) which is adapted to jawbone density variations and an implant (1) which is formed in a corresponding manner to the drill (21) and which is also adapted to bone density variations. According to the invention, the implant (1) and the drill (2) comprise a plurality of zones over the heights thereof, which are suitably produced such that the drill (21) alone is used to form the seat for the implant (1). The invention is suitable for high-precision dental implantology.

Abstract: A single dental appliance that both alleviates snoring and protects teeth from bruxism. The appliance (10) has an upper section (12) which is mounted on the upper jaw. Opposing the upper section (12) is a lower section (14) which is mounted on the lower jaw. Both the upper and lower section have an anterior region (16, 18) and two posterior regions (20, 22; 24, 26). A hard outer shell (32, 34) secures in a soft inner liner (28, 30) which conforms with the teeth and cushions the jaw against impact forces. The hard outer shell (32, 34) serves to protect the teeth against grinding. The combination of the liner and the shell distribute forces associated with grinding.
