Description

Dental tool

Technical Field

The present invention relates to a dental tool, and more particularly, to a dental tool with measuring effect, improved detection feeling, and convenient use.

Background

Accordingly, a great number of tools are currently used in dentistry, such as probes (explorers), mouth mirrors (mirrors), forceps (pliers), etc., for performing a dental examination or treatment, wherein the probes mainly provide a dentist with a tactile sense to inspect and determine whether a patient's teeth have abnormal parts, such as the depth of a periodontal pocket, the thickness of a gum, the loose state of the teeth, the width of a tooth space, etc., the existing probe mainly has a rod-shaped handle portion, one or two ends of which are respectively provided with a needle portion as a working end, so that the dentist can look at the patient's teeth through the needle portion by holding the handle portion to perform the examination; however, the conventional probe has only a single effect of detecting teeth, and cannot provide other uses and effects, wherein when a patient needs to implant teeth, most of the surgical guide plates corresponding to the positions of the teeth of the patient need to be manufactured to serve as measurement references for positions of subsequent drilling, artificial tooth root application and the like.

Furthermore, the needle portion of the conventional probe is made of stainless steel and the like, has a certain structural strength, and not only can the hard needle portion cause discomfort to a patient when the probe is used for probing teeth, but also the needle portion can be bent or deformed after the conventional probe is dropped on the ground or collides with other objects, so that the subsequent reusability is influenced.
