Example Embodiment

[0045] FIG. 1 shows an example of a low-speed grinding method in which the method is used to form a cavity or dimple 5 in the tissue 6 of a patient. In this specific case, the tissue is the maxilla, and the cavity is formed to accommodate the dental implant 4. In this method, as part of the initial stage 1, the cortical layer or the hardest exterior of the bone 6 is ground. Next is the intermediate grinding stage 2 which defines the cavity 5. Finally, the method ends with the counterboring stage 3 of widening the cavity 5 to accommodate the head 18 of the dental implant 4.

[0046] As pointed out in the description of the present invention, the necessary tools are used in each grinding stage to produce the desired effect on the cavity and the like. In this regard, the starter drill 7 used during the initial phase 1 is characterized by a very sharp conical top 19 which enables the starter drill to start grinding the cavity. In addition, the counter-boring drill 9 used during the co...

Abstract

Milling procedure performed on the patient's bone or other tissue in order to form in said tissue a cavity (5) of a shape and size that allows it to house an implant (4) (or for other purposes where the tissue must regenerate) wherein milling is performed at low speeds and without irrigation without the tissue heating up and necrosis occurring in the tissue. The special design of the mill tools (8, 9) enables the tissue particles extracted during the milling process to be collected without using a suction machine. Said particles are in optimal biological condition for use in autografting due to the fact that neither over heating nor irrigation occur during the milling process.

Description

technical field [0001] The present invention relates to techniques for drilling or grinding of bone, cartilage, and other tissues, the intended medical purpose of which is generally the implantation of prostheses, screws for osteosynthesis, or other elements into knees, hips, spine, and other bones or organizationally. One of the most important applications in the field of implantology and maxillofacial surgery is the drilling of holes in the patient's maxilla for placement of implant teeth. Background technique [0002] When used in particular for dental implants, the grinding method involves progressively drilling the bone by progressively inserting burrs of increasing diameter to form cavities of suitable size for the implant or prosthesis. The grinding method involves rotating the tool or burr at the desired speed. The exact rotational speed parameters are determined by several factors, notably the geometry of the burr used and the sequence of grinding process stages. ...
