Embodiment 1

[0039] Such as figure 1 and figure 2 As shown, the pulp cavity access guide plate for incisors and canines includes a guide plate body 1, and a guide cylinder 3 is also arranged on the guide plate body 1, and a central hole 6 is arranged in the center of the guide cylinder 3, In the wall thickness direction of the guide cylinder 3, the side wall of the guide cylinder 3 is also provided with a second groove body 5 that runs through the side wall of the guide cylinder 3. One side intersects.

[0040] The existing digital pulp cavity access solutions for root canal treatment include: solutions based on high-speed mobile phone burs, slow-speed mobile phone burs, and straight-line pathways. The burs include:

[0041] The cutting part is divided into: split drill, inverted cone drill, ball drill, columnar emery, flame emery, etc., the diameter is generally: 0.5 ~ 1.5mm;

[0042] Connecting part: The part that is submerged in the dental handpiece and connected to it. In the ISO s...

Embodiment 2

[0049] The present embodiment is further limited on the basis of embodiment 1, as figure 1 and figure 2 As shown, in order to make the preparation of the guide plate convenient and accurate through the existing scanning technology and 3D printing technology, it is set as an integrated structure formed by the combination of the guide plate body 1 and the guide cylinder 3 .

[0050] In order to realize the limitation of the specific axis direction of the bur based on the guide plate, so as to realize the accurate preparation of the pulp hole, it is set as follows: the material of the guide cylinder 3 is plastic or rubber, and it also includes a sleeve made of metal. Sleeve 2, in the wall thickness direction of the sleeve 2, the side wall of the sleeve 2 is also provided with a first groove body 4 penetrating through the side wall of the sleeve 2, one end of the first groove body 4 and one end of the sleeve 2 intersect;

[0051] The central hole 6 is used as the installation h...

Abstract

The invention discloses a dental pulp cavity approach guide plate for incisors and canines. The dental pulp cavity approach guide plate includes a guide plate body, a guide cylinder is further arranged on the guide plate body, and a center hole is formed in the center of the guide cylinder. In the wall thickness direction of the guide cylinder, a second groove body penetrating through the side wall of the guide cylinder is further formed in the side wall of the guide cylinder, and one end of the second groove body intersects the side, away from the guide plate body, of the guide cylinder. According to the structural design of the guide plate, performing of the pulp opening operation of dental pulp cavity approach is facilitated, the comfort of patients is improved, and realizing of minimally invasive pulp opening is facilitated.

Description

technical field [0001] The invention relates to the field of dental pulp cavity access hole opening tools, in particular to a pulp cavity approach opening guide plate for incisors and canines. Background technique [0002] In oral root canal treatment, the opening of the pulp cavity is the first step in the dental operation procedure. Good pulp cavity design and opening quality are of great significance to oral root canal treatment and tooth protection. [0003] Pulp cavity approach is also called pulp cavity entry, which refers to making a hole from the outside of the crown to enter the pulp chamber or pulp cavity, also known as pulp opening, which requires the hole to reach the root canal directly. The proper shape of the pulp opening hole should not only facilitate the establishment of a straight path for instruments to enter the root canal, but also preserve the tooth tissue to the maximum extent to ensure retention and resistance. big dependency. [0004] Due to the i...
