(a) TECHNICAL FIELD OF THE INVENTION
The present invention relates to a light beam dental hand piece for assisting depth and angle measurement, and more particularly to a dental hand piece with a measuring scale capable of measuring depth and angle on a hand piece head.
(b) DESCRIPTION OF THE PRIOR ART
During dental implantation, a dental hand piece engaged with drill must be used for drilling the alveolar bone in the patient's mouth. When drilling, the dentist must first evaluate the patient's dentition, implant size and the depth of a hole. The depth of the drilling will lead to the stability of the implant installation, so when drilling, it is necessary to closely observe the depth of the drill to avoid improper dental implant installation.
Currently, the drill used for drilling bones will be marked with a color scale to distinguish the depth. However, when the dentist is drilling, the color scale for distinguishing the depth are covered with blood and water, which makes it difficult for the dentist to see clearly during the process; therefore, it increases surgical risk and dentist pressure. Further, when drilling, the dentist must control the drilling depth with a skilled experience. If it is an osteoporosis patient, the drilling force needs a higher precision, and the conventional drills are more likely to cause the problem of excessive or insufficient drilling depth. Therefore, at present, there is an urgent need for a dental hand piece that assists in depth and angle measurement to improve the above shortcomings and to improve the success rate of dental implants.
In view of this, the inventor has invested a lot of research, development and effort, making breakthroughs and innovations, hoping to solve the current shortcomings with novel technical methods, not only bringing better products to the society, but also promoting industrial development at the same time.
SUMMARY OF THE INVENTION
The main purpose of the present invention is to provide a light beam dental hand piece with measuring scale for assisting depth and angle measurement, so as to provide the dentist with a clear indication of the measuring scale when drilling, grinding, and drilling alveolar bone, to avoid the problem of excessive or insufficient drilling depth, in order to achieve the stability of dental implants and can avoid damage to body tissues due to incorrect positioning.
