Abstract: A dental drill bit is combined with a surgical template provided with a guide hole adapted to guide the dental drill bit directly or via a guide sleeve provided in the guide hole. The dental drill bit has a first end, a second end, a spherical drill head arranged at the first end, and at least one helical flute extending from the spherical drill head towards the second end. The portion of the dental drill bit having the at least one helical flute is substantially cylindrical. A use of such a dental drill bit and a method of drilling a hole in an oblique bone surface of a jaw bone of a patient are also provided.

Abstract: The present invention concerns a method for measuring a chip integrated structure (1) including at least one coil (5) having a plurality of turns (6). The present invention is characterized on the following steps: measuring the resistance across the terminals of first and second portions of said coil (5), corresponding to two different numbers of turns of the coil; computing the ratio of the measured resistances across the terminals of first and second portions of the coil (5); comparing the ratio to a constant measured from a sample of resistance measurements made on coils of identical geometry; and determining the presence or the absence of a short circuit between at least two turns of one of said portions of said coil (5), when the ratio is different from or equal to said constant respectively. The present invention further concerns an integrated circuit which is able to allow implementation of the above mentioned measuring method.

Abstract: The present invention concerns an integrated circuit structure (1) formed in a substrate (2) and including at least one integrated circuit element (3, 4), an antenna coil (5) capable of transmitting and/or receiving data, and associated with said integrated circuit element(s) (3, 4); and a metal protective ring (20) situated at the periphery of the integrated circuit structure (1). The present invention is characterised in that said protective ring (20) comprises at least one ohmic interruption, so that it does not form a closed circuit on itself. The integrated circuit structure (1) according to the invention is improved in that the operation of the antenna coil (5) is made insensitive to the presence of the protective ring (20).
