Technical Field
The utility model relates to the technical field of medical treatment, in particular to an improved injector for assisting temporary crown repair.
Background
The temporary crown is a temporary prosthesis currently used for tooth restoration, and not only can protect gingiva and living marrow abutments, but also can maintain the morphology of the abutments and the basic chewing function of teeth. The method for preparing the temporary crown is commonly used in clinic, wherein an impression is prepared before the preparation of a tooth body, after the preparation of the tooth body is finished, the mixed temporary crown material is placed into a trimmed impression abutment, then the impression is placed in the mouth to be in place, and after the material is solidified, the temporary crown is taken down for adjustment and then is bonded. The common temporary crown repairing material in the outpatient department of the oral cavity is a mixing type DMG (dimethyl methacrylate) quick setting material, the mixing is carried out according to a certain proportion by matching with a mixing knife used by a nurse, the temporary crown material is placed into an abutment area of an impression for a plurality of times by using the tip part of the mixing knife, and a tray needs to be vibrated so as to reduce the generation of bubbles. The nursing operation needs to be completed within 1 min. The temporary crown in the anterior tooth area is prepared, because of the anatomical form of the anterior teeth, the impression is in a form of being wide at the top and narrow at the bottom, and the temporary crown material is difficult to put in place by using the tip of the stirring knife, so that the temporary crown generates air bubbles and needs to be prepared again.
In clinic, when a plurality of temporary crowns for anterior teeth are repaired, a nurse needs to perform an operation method by the method, and the time required for completely putting the temporary crown material into the impression abutment is prolonged, so that the operation time of a doctor is shortened, and even the material is solidified outside the oral cavity. When the temporary crown has bubbles and the corner cut is missing, the doctor needs to prepare the temporary crown again or even for a plurality of times, thereby increasing the workload of medical workers, reducing the comfort level of patients and wasting materials. In order to improve the working efficiency of doctors, an improved injector for assisting the repair of temporary crowns is designed.
