Dental handpiece with auxiliary measurement function

Technical Field

The present invention relates to a dental handpiece with auxiliary measurement, and more particularly to a dental handpiece with a measurable depth and angle on a handpiece.

Background

The artificial tooth implantation can provide the tooth-missing patient with the function of restoring the beautiful appearance and chewing of the tooth, the general tooth implantation operation is to implant a tooth implant body made of titanium metal or zirconium dioxide as a material into the alveolar bone of the oral cavity of the patient to be used as the tooth root similar to the original tooth of the tooth, and after the tooth implant body is tightly combined with the bone, the artificial tooth is manufactured on the tooth root of the titanium metal or zirconium dioxide. During the dental implantation procedure, a dental handpiece (dental hand piece) must be used and a drill must be attached to perform a drilling procedure on the alveolar bone of the patient's mouth. When drilling, a dentist needs to firstly evaluate the condition of the tooth bone of a patient and the size of an implant, and set the depth of the drilled hole, wherein the depth of the drilled hole can cause the stability of the installation of the implant, and the drilling depth of a drill needs to be strictly observed during the drilling so as to avoid the improper installation of the dental implant.

At present, color block scales for distinguishing depths are marked on a drill bit used for drilling the dentate bones, however, blood and water can cover the color block scales for distinguishing depths when a dentist drills the holes, so that the dentist is not easy to see clearly in the process, and the operation risk and the pressure of the dentist are increased. Secondly, the dentist must control the drilling depth with a skilled hand feeling during drilling, and in case of osteoporosis patients, the drilling force needs higher precision, and the known drill bit is easy to cause the problem of too much or too little drilling depth.

Therefore, there is a need for a dental handpiece with auxiliary measurement to improve the above-mentioned disadvantages and to improve the success rate of dental implantation.
