Cutting saw for proximal surface sheet of fixed partial denture and processing method of cutting saw

Abstract

The invention discloses a cutting saw for a proximal surface sheet of fixed partial denture and a processing method of the cutting saw. The cutting saw is of a toothed structure; the width of teeth is 10mu m, the apex angle of the teeth is 30 to 60 degrees, the total length of the saw is 50 to 150mm, the width of the saw is 2 to 10mm, and thickness of the saw is 30 to 100mu m; during processing, a cleaned stainless steel sheet is putted on a laser cutting machine by adopting a laser cutting method, and parameters of the laser cutting machine are adjusted for micro processing; during use, the current of a laser power supply is 10 to 20A, and the scribing speed is 1 to 3mm / s; finally, edges are deburred and cleaned again. The cutting saw disclosed by the invention can be used for quickly removing a residual bonding agent of the proximal surface of the teeth and polishing the surface; compared with other cutting saws for the proximal surface, the process disclosed by the invention has the advantages of high microprocessing precision, excellent processing speed, higher rate of finished product and good removing effect on the proximal surface; the product can be repeatedly used, the working efficiency can be improved, and the use cost is reduced.

Description

technical field [0001] The invention relates to the field of commonly used orthodontic instruments, in particular to a fixed denture adjacent surface cutting saw and a processing method thereof. Background technique [0002] As a commonly used instrument in orthodontics, the interproximal enamel reduction saw is mainly used for interproximal enamel reduction (IER). It is a clinical operation through the grinding, reshaping, obtaining space or adjusting the size of the interproximal enamel, which can give Orthodontic treatment provides space or improves the shape and size of teeth to achieve the purpose of orthodontic treatment. Its main purpose is to relieve malocclusion such as mild crowding of the dentition or uncoordinated teeth in the upper and lower dental arches (ie abnormal Bolton ratio). Nowadays, many physicians in North America and Europe have taken "tooth extraction as much as possible" as an orthodontic principle, and the proportion of non-extraction cases in th...

Problems solved by technology

[0003] With the development of oral restorative technology, patients have higher and higher demand for fixed denture restoration. As long as the fixed restoration is done, adhesives will be used, which will lead to a more serious problem: the excess adhesive after the restoration is bonded. Adhesive is difficult to clean

However, the dental floss is not strong enough and it is easy to break during use; the scalpel and scaler can only remove the adhesive on the outer gap of the teeth, and the contact area cannot be cleaned; the rapid mobile phone grinding method is not easy to implement and may hurt the gums or grind to the teeth
