Description

Dental drill guide

Technical Field

Background

Dental implant refers to a dental defect restoration method for supporting and retaining an upper dental restoration on the basis of a lower structure implanted in bone tissue. It is made of artificial material (such as metal, ceramic, etc.) and is implanted into tissue (usually upper and lower jaws) by surgical method to obtain firm retention support of bone tissue, and the dental prosthesis is connected to the upper portion of the support by means of special equipment and mode.

Dental drills are commonly used in dental restorative implant procedures. In the process of planting teeth by using a dental drill, a dental drill guide is needed to play a role in guiding a drill bit to open holes of dental sockets.

However, due to inconsistent sizes of the edentulous areas of different patients or the same patient, the guides that can be used are different in size, and the involuntary slight closing of the patient's upper and lower jaws also reduces the area of the drilled holes to be performed, requiring additional support members, but the support members themselves also affect the use of the dental drill.

Detailed Description

The present utility model will be further described with reference to the following examples in order to better understand the technical solutions of the present utility model and to make the above features, objects and advantages of the present utility model more clearly understood. The examples are only for illustrating the present utility model and are not intended to limit the scope of the present utility model.

As shown in fig. 1 to 5, the present utility model includes: a guide ring (1), a limit piece (2) positioned on the side wall of the guide ring (1), a bearing piece (3) connected with the limit piece (2), a supporting piece (4) connected with the bearing piece (3) and a fixing piece (5) positioned at the other end of the supporting piece (4),

The time period of use is after incising the gums and before the dental alveolus is drilled.

When the novel tooth-opening type guide ring is used, the guide ring (1), the limiting piece (2) and the bearing piece (3) are connected and fixed to form a fixing assembly of the guide ring (1), and then a support piece (4) with proper length is selected to be connected with the fixing piece (5) according to the opening degree of teeth of a patient.

The cavity formed by the limiting piece (2) and the bearing piece (3) is attached to the tooth at one side of the drilling hole to form fixation, and the guide ring (1) is returned to the position right above the drilling hole to serve as guide. Because patients still have a tendency to close the mouth to some extent after anesthesia. At this time, the fixing piece (5) is firstly attached to the teeth on the upper part, then the other end supporting piece (4) is connected with the bearing piece (3), and the whole fixing is completed in a way of mutually supporting the upper jaw and the lower jaw.

Referring to fig. 1, 4 and 5, as a specific structure of the support (4):

the support piece (4) comprises a double groove piece (41) and a single groove piece (42) which are mutually embedded and fixed, the whole double groove piece (41) is cylindrical, embedded grooves are formed in the upper side and the lower side of the double groove piece, one end of the single groove piece (42) is an embedded groove, and the other end of the single groove piece is a third convex plate.

In a single selection, the double groove (41) will generally have a plurality of length specifications, the length values are distributed between 1 cm and 2cm, and the single groove (42) is unified to be 2cm. The distance between the upper teeth and the lower teeth after the oral cavity of the human body is opened is generally 5-7cm, and the oral cavity of the patient can be expanded as much as possible by the splicing of the double groove parts (41) and the single groove parts (42) and the fixing piece (5).

To assist in the use of this embodiment:

the guide ring (1) is wide in upper part and narrow in lower part, the narrowest part of the inner wall is larger than the width of the dental drill, and the biggest part of the outer wall is smaller than the spacing between teeth at two sides of the position.
