Abstract: A burr comprises a shaft (7) and a conical head (8). The circumferential surface of the head of the burr is of a material-removing design merely within a circumferentially limited area (9). The sum of the angle which is occupied by the circumferentially limited area relative to the centre axis of the head of the burr and a rotary angle, through which the burr during operation is adapted to oscillate, is less than 360 DEG .

Abstract: A prefabricated inlay (1) for restoring a tooth by application and fixation in a cavity prepared in the tooth and having essentially the same shape as the inlay part adapted for insertion, is provided with a pin (6) which projects from the inlay part not adapted for insertion and which is arranged to be received in an inlay holder. The whole inlay (1) is made of a material translucent to light that is suitable for curing a light-curing material used for fixing the inlay in the cavity. The inlay holder has a light source and a light guide having a tip (18) with a recess (19) for receiving the pin (6) of the inlay (1), such that the light generated by the light source can be guided through the light guide and the inlay (1) to the light-curing material. A tooth restoration set comprises a plurality of prefabricated frustoconical inlays (1), preferably having the same cone angle as well as several different narrow-end diameters, and a plurality of frustoconical burrs having the same cone angle as the inlays (1) as well as corresponding different narrow-end diameters.
