Tray puncher

Abstract

The invention discloses a tray puncher. The tray puncher comprises a first forceps body and a second forceps body, wherein the first forceps body comprises a first forceps handle and a second forcepshandle; the second forceps body comprises a second forceps handle and a second forceps handle, a first forceps tip and a second forceps tip are connected to one end of the first forceps handle and oneend of the second forceps handle, and the first forceps body and the second forceps body are hinged through a joint; a bulging tenon port is arranged at the tail end of the first forceps tip, a mortise is formed in the tail end of the second forceps tip, the tenon port and the mortise are meshed and matched, and meshing surfaces of the tenon port and the mortise are sawtooth structures; the outerend surface of the forceps body provided with the tenon port is a frosted surface. The tray puncher is convenient to operate, time-saving, labor-saving and convenient, and the working efficiency andthe working quality of doctors can be effectively improved, so that an impression is more accurate during preparation. The tray puncher is made of stainless steel and is convenient to clean, disinfectand sterilize, hospital infection is prevented, the tray puncher can be repeatedly used, and the cost is greatly saved. Therefore, the puncher has broad application prospects in the oral field.

Description

technical field [0001] The invention relates to a punching device for trays during implant restoration and mold taking in the later stage of dental implant surgery, in particular to a pliers puncher for plastic disposable trays that can be selected for punching tooth positions. Background technique [0002] The following impression techniques are commonly used clinically when taking impressions for implant restoration in the later stage of implant surgery: transgingival implant non-fenestration, octagonal abutment system non-fenestration and transgingival implant fenestration. The windowed impression refers to the impression made by using a windowed tray and a transfer body with a set screw in the center. Compared with the non-opened impression method, the windowed impression has higher accuracy, so clinical This method is often used to take impressions for implant restorations. [0003] However, the open window impression technology has certain requirements on the tray. A...

Problems solved by technology

This action not only greatly increases the workload and working hours of the doctor, but also in the process of grinding the window opening, due to the heat generated by friction during grinding, the temperature will be high, which will easily lead to the deformation of the tray and affect the effect of the impression.

The polished plastic debris is also easy to pollute the environment, and even splash into the eyes of doctors and patients, causing eye damage

Moreover, the edge of the polished tray is rough, which is easy to damage the corners of the patient's mouth and oral mucosa
