  • Publication number: 20070088361
    Abstract: The invention relates to a surgical drill for osteotomy. The surgical drill comprises: a shank, a base portion, a cutting blade, a non-cutting section and a groove. The base portion is formed on the shank. The cutting blade is formed on the edge of the base portion. The non-cutting section is formed on the top of the base portion. The groove is formed on a peripheral section of the base portion, and is adjacent to the cutting blade and extends along a longitudinal direction. According to the invention, the surgical drill utilizes one single cutting blade to drill a socket formed by an implant drill. Because the fewer the blades are, the slower the working speed can be, so the bottom of the socket is not easy to penetrate the bony structure. By using the surgical drill of the invention, an intact bony plate between the implant and sinus membrane is more likely to obtain. Another type of the surgical drill of the invention can turn a tapered socket into a straight one at the posterior mandible.

  • Publication number: 20050130910
    Abstract: The present invention relates to immobilized N-substituted tricyclic 3-aminopyrazole compounds of Formula 1 as tools for the identification of bimolecular targets in cells of therapeutic significance, profiling the selectivity of compounds, prediction of possible related toxicities and exploration of mechanisms of action in biological systems for therapeutic indications related to compounds. These agents can be used to identify biomolecules with the potential to interact with the immobilized reagent. The identified biomolecule may be then be used as a therapeutic target, serve as a marker of drug action, or alternatively describe an untoward or toxic potential of the immobilized agent.
