Description

1 TARIFF A METHOD FOR MANUFACTURING AN ENDODONTIC ROOT CANAL INSTRUMENT Technical Area The invention relates to a method for manufacturing an endodontic root canal instrument. State of the Art 5 Nitinol (nickel-titanium, NiTi) alloy is used in the production of medical instruments due to its structural properties. especially endodontic root canal instruments, in dentistry, veterinary medicine and It is a material widely used in various dental industry applications. The mechanical behavior of the alloy, crystallographic differences between austenitic and martensitic phases. It is based on transformation, and the applied heat treatment parameters are 10 for this transformation. It directly determines their temperatures and, consequently, the physical properties of the instrument. In the current state of the technique, endodontic root canals are constructed using nitinol alloy wires. The devices are classified into three different phases based on their mechanical properties: silver phase, gold phase, and blue phase. They are produced in the phase structure category. Each phase structure is distinctly different from the others. obtained by subjecting to varying temperature values, time intervals and processing conditions 15 This situation involves independent heat treatment cycles for each phase in the production process. This necessitates their separate implementation; and this necessity refers to production times. This leads to longer working hours, increased labor requirements, and higher energy consumption. This opens up a production constraint in the known state of the art, namely the existing manufacturing processes. It negatively impacts its efficiency and scalability; unnecessarily increases production costs. It increases. From the end-user perspective, the current state of each phase structure is... The fact that it is only available on a single device creates significant functional difficulties in clinical applications. This is why. Each of the silver, gold, and blue phases affects hardness, flexibility, and cutting performance. They exhibit different physical characteristics in terms of canal anatomy and treatment. 25 given that the process simultaneously presents different mechanical requirements, Existing instruments with a single-phase characteristic do not adequately meet these requirements. This prevents the physician from meeting the demand; it forces the doctor to change equipment and prolongs the treatment process. In the current state of the art, these three different phase structures can be combined into a single nitinol device body. 30 2 a doctrine relating to any method or production technique that makes its introduction possible It is not available. In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion... Due to its shortcomings, an improvement is needed in the relevant technical field. It has been made. 5 Purpose of the Invention The invention was created by drawing inspiration from existing situations and overcoming the aforementioned drawbacks. It aims to solve the problem. The invention relates to wires made from nitinol (NiTi) alloy, which have different phase structures due to heat treatment methods. 10 of the existing techniques in the production processes of the acquired tools It relates to a production method that aims to eliminate production constraints. The method in question involves nitinol, which is used in dentistry, the dental sector, and veterinary medicine. Alloy wire-based instruments have three different crystallographic phases: silver phase, gold phase, and blue phase. phase structure on a single tool body, in a single manufacturing process and process repetition It makes it possible to obtain it without needing anything else. 15 In the current state of the art, each phase structure is obtained by a separate heat treatment cycle. It is known that in this context, the silver phase is kept at 150–250 °C for 6 hours, and the gold phase... Processing at 250–400 °C for 6 hours and blue phase at 400–500 °C for 6 hours. It is subjected to. These three independent heat treatment cycles, supported by the mold, total eighteen. It requires a production time exceeding 20 hours, high energy consumption, and intensive labor. The invention's primary goal is to radically transform this inefficient and costly multi-stage process. This transformation is due to the production of laser engraving machine technology. This is achieved by integrating it into the process. In the method developed within the scope of the invention, After a phase structure is first obtained on the nitinol wire, the remaining regions... Phase transformations are performed via a laser marking machine, each phase structure having 25 different characteristics. This is achieved using wavelength and frequency parameters. This approach Thanks to this, each phase conversion process takes an extremely short time, approximately one minute. It can be completed and the laser application is done only by positioning the device. It can be precisely directed to the desired area of ​​its body. This production transformation provided by the invention reduces total production time, energy consumption, and labor. It aims to significantly reduce power requirements. In addition, the laser... 3 Based on regional phase transformation technique, high precision of the processing area Because it allows for the determination of phase boundaries, it increases control over phase limits and production. It improves its repeatability. As a result, this invention, nitinol alloy wire-based tool simultaneously improving process efficiency, cost effectiveness, and product quality in production. 5 represents an industrial-scale applicable technical solution aimed at improvement is doing. The structural and characteristic features and all the advantages of the invention are given in the figures below. This becomes clearer thanks to the detailed explanation written with references to these figures. This will be understood, and therefore the evaluation should also take these forms and detailed explanations into consideration. It needs to be done by taking precautions. 10 Figures that will help understand the invention. Figure 1 shows a representative view of the application of the method described in the invention. Explanation of Part References 1 Silver zone 2 Gold zones 15 3 Blue zones 4 Laser marking machines Engine 6 Laser beams Detailed Description of the Invention 20 In this detailed explanation, the preferred configurations of the method in question are described only. This is explained to facilitate a better understanding of the subject. The invention relates to silver zone (1), gold zone (2) and tools made from nitinol (NiTi) alloy wires. three different crystallographic phase structures including the blue region (3) in a single instrument body 25 with regional laser energy applied on it via laser marking machine (4). It relates to a production method based on obtaining [the desired result]. This method... By replacing conventional oven-based heat treatment processes, it reduces production time and energy. It drastically reduces consumption and labor requirements. The laser marking machine (4) used in the invention method has a power of 30 watts. 30 working and aiming to trigger phase transformation in different regions of the nitinol alloy 4 a laser beam (6) that can produce different frequency and wavelength parameters It is a device. Laser beams (6) are emitted from the laser marking machine (4) and the nitinol alloy By focusing the wire on the target region, the region is brought down to its phase transition temperature in a short time. It is an energy beam that delivers energy in a short time. This high-frequency energy input is unlike conventional Eliminates the lengthy furnace heating and cooling cycles required in these methods. 5 removing; each phase conversion process takes approximately one minute. It allows for its completion. Laser energy is applied homogeneously and evenly to the entire circumferential surface of the Nitinol alloy wire. In order to transfer it, the production setup includes a motor (5). Motor (5) is a dremel It is a type of motor that rotates the nitinol alloy wire 360 ​​degrees around its own axis to power the laser 10. This mechanism ensures that the rays (6) contact the wire surface at an equal angle. This prevents the transformation from occurring only on one surface of the wire and Regional phase homogeneity is ensured. The phase transformation process within the scope of the invention is the power of the laser marking machine (4). It relies on the precise adjustment of the parameter. Power range 40% to 45% 15 When the laser energy is applied between them, it targets the silver region of the nitinol alloy. (1) brings the temperature corresponding to its characteristic and hard phase structure in this region is obtained. When the power range is between 25% and 35%, the applied rate is higher. low energy level, the relevant region of the nitinol alloy has the characteristic of gold region (2) transporting it to the corresponding temperature and forming a medium-hard phase structure in this region 20 The blue region (3) represents the flexible phase structure and the obtained region The power parameters required for this are used for the silver region (1) and the gold region (2). This requires the application of laser energy that varies in power ranges. All three phases The same principle applies in its transformation: the applied power level only affects the nitinol alloy. in the target region and only to the temperature value corresponding to the desired phase transformation 25 This ensures that it reaches its destination quickly; thus, it is essential for each phase in traditional methods. The long heating time is completely eliminated. In the method described in the invention, the need for mold use is completely eliminated. The multi-stage process sequence is reduced to a single stage, and each phase transformation is approximately Within one minute, 30 can be detected by precise laser positioning to the relevant area. This is being carried out.
