AI Technical Summary
In the existing dental restoration technology, it is difficult for dentists to improve operating accuracy and fault tolerance when filling teeth, resulting in uneven filling of composite resin.
An adjustable composite resin filler for tooth restoration is designed. By adjusting the height of the limit stop ring and limiting its movement with the limit marking rod, the limit position of the downward movement of the push rod and the piston is limited, thereby improving the filling accuracy. At the same time, a longitudinal ruler is provided to facilitate the dentist to determine the rotation position of the limit stop ring.
Through the design of this filler, the dentist can more accurately control the filling amount of the composite resin, improve the accuracy of tooth repair filling and the fault tolerance of operation, and avoid the problem of excessive or too small filling amount.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dental restoration, and particularly relates to an adjustable composite resin filler for dental restoration. Background Art
[0002] Tooth defect is a common disease in oral clinic. Among them, dental caries is the main cause of tooth defect. When a carious cavity forms on a person's tooth, generally in clinical practice, the filling method is adopted, and a composite resin material is used to fill the defect on the tooth surface to achieve the purpose of filling and strengthening the tooth. When a dentist performs filling and restoration on multiple teeth, a filler with a quantitative adjustment function can improve the error tolerance rate of the operation and the control accuracy of tooth restoration filling. Summary of the Invention
[0003] The technical problem to be solved by the utility model is to provide an adjustable composite resin filler for dental restoration that can improve the filling accuracy and error tolerance rate of dentists during dental restoration.
[0004] To solve the above technical problem, the present invention is realized through the following technical solutions: An adjustable composite resin filler for dental restoration, comprising a filler barrel, a push rod, a pressure ring, a limit marking rod and a limit stop ring. A piston is slidably and sealingly installed in the filler barrel. The lower end of the push rod is coaxially and fixedly installed with the piston. A groove is provided on the bottom surface of the pressure ring. The limit marking rod is fixedly embedded in the groove on the bottom surface of the pressure ring. The pressure ring is fixedly installed on the top surface of the filler barrel. The push rod is provided with an external thread. The limit stop ring is screwed onto the external thread of the push rod. A jack is provided through the push rod. The limit marking rod is slidably installed in the jack. The push rod is provided with a longitudinal scale.
[0005] Preferably, a mesh anti-slip pattern is provided on the outer surface of the limit stop ring.
[0006] Preferably, the longitudinal scale is provided on the inner wall of the jack, and the longitudinal scale is set as a percentage scale.
[0007] Preferably, the pressure ring is screwed and fixedly installed on the top surface of the filler barrel, and the limit marking rod is pressed and fixed on the top surface of the filler barrel by the pressure ring.
[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: By adjusting the height position of the limit stop ring and limiting the extreme downward movement position of the adjusted limit stop ring through the limit marking rod, the present filler restricts the extreme downward movement position of the combination of the push rod and the piston, thereby improving the accuracy of a dentist's single-time filling of composite resin into a patient's tooth, and at the same time increasing the error tolerance of the operation. In addition, by setting a longitudinal scale, it is convenient for the dentist to accurately judge the upward rotation position of the limit stop ring, and it has the advantage of convenient use. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The present utility model will be further described below with reference to the accompanying drawings.
[0010] Figure 1 It is a schematic diagram of the internal structure of the present utility model.
[0011] Figure 2 It is a schematic diagram of the arrangement structure of the insertion hole on the push rod. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0012] The present utility model will be described in detail below in conjunction with the specific embodiments:
[0013] As Figure 1 and Figure 2 shown, a tooth restoration adjustable composite resin filler includes a filler barrel 1, a push rod 2, a pressure ring 3, a limit marking rod 4 and a limit stop ring 5. A piston is slidably and sealingly installed in the filler barrel 1. The lower end of the push rod 2 is coaxially and fixedly installed with the piston. A groove is provided on the bottom surface of the pressure ring 3. The limit marking rod 4 is fixedly embedded in the groove on the bottom surface of the pressure ring 3. The pressure ring 3 is fixedly installed on the top surface of the filler barrel 1. An external thread is provided on the push rod 2. The limit stop ring 5 is screwed onto the external thread of the push rod 2. An insertion hole 21 is provided through the push rod 2. The limit marking rod 4 is slidably installed in the insertion hole 21. The push rod 2 is provided with a longitudinal scale.
[0014] A mesh anti-slip pattern is provided on the outer surface of the limit stop ring 5 to facilitate the user's rotation operation of the limit stop ring 5.
[0015] The longitudinal scale is provided on the inner wall of the insertion hole 21. The longitudinal scale is set as a percentage scale. The percentage scale is divided with 5% as the minimum unit. The numerical range of the percentage scale is 0%-100%. That is, 100% corresponds to the unused filler barrel 1, and 0% represents that the composite resin in the filler barrel 1 is exhausted.
[0016] The pressing ring 3 is fixedly installed on the top surface of the filler cylinder body 1 by screwing, which has the advantage of being convenient for assembly and fixation. The limit marking rod 4 is pressed and fixed on the top surface of the filler cylinder body 1 by the pressing ring 3. Even if the limit marking rod 4 and the pressing ring 3 become loose, under the pressing action of the pressing ring 3, the limit marking rod 4 still has the advantage of high installation firmness.
[0017] When the dentist uses this filler to repair and fill composite resin for the patient's teeth, according to the dosage required for a single filling, the dentist rotates the limit stop ring 5 to move upward along the push rod 2, and uses the longitudinal scale as a reference for adjusting the limit stop ring 5. In this way, when the dentist pushes the combination of the push rod 2 and the piston to extrude the composite resin from the filling head at the lower part of the filler cylinder body 1, after the limit stop ring 5 contacts the limit marking rod 4, the downward movement of the combination of the push rod 2 and the piston is restricted, which can avoid the problem that the dentist fills too much composite resin into the patient's teeth at a single time.
