Abstract: A planning and guiding method and excavation guiding device correctly implant an artificial tooth root at a predetermined site, perform various excavation processes on a cortical bone section and a spongy bone section by stage-based guidance, and guide eccentric excavation of the cortical bone section and concentric excavation of the spongy bone section according to a bone pattern, such that the artificial tooth root thus implanted is not only positioned at a planned ideal site but also manifests appropriate initial stability.

Abstract: A drill bit guiding device for dental implant surgery comprises a dental implant platform positioning ruler, a connecting fixing member and a drill bit guide. The dental implant platform positioning ruler is used to configure an ideal dental implant placement position on a tooth model. Then, the connecting fixing member is embedded into the dental implant platform positioning ruler, and a resin material connects extensions of the connecting fixing member to neighboring teeth on two sides of the dental implant position. Finally, the connecting fixing member and the resin material are removed and placed on an oral gum to be treated. Meanwhile, the drill bit guide is inserted into the connecting fixing member, so that a hole satisfying the ideal dental implant position and angle is drilled at the planned dental implant position through a through hole of the drill bit guide.

Abstract: A dental floss pick is composed of a frame, a floss and a grip portion, wherein the frame has a first section and a second section. The first section extends from one end of the frame to a predetermined range and the second section extends from the first section to connect one end of the grip portion. Because the first section defines a first tooth-accommodating area with a height, which is smaller than a distance between the occlusal surface and the interdental papilliae, therefore, when a user places the floss into the slits between the teeth, the floss is limited in depth by the first tooth-accommodating area to avoid damaging the gum. Moreover, the floss is modified into two sections with different materials and shapes for cleaning different teeth slits at different location and characteristics to improve the cleaning convenience and avoid gun injury.
