Description

Oral cavity impression transfer box

Technical Field

The utility model belongs to the technical field of oral impressions, and particularly relates to an oral impression transfer box.

Background

The preparation of various dental restorations generally comprises the steps of firstly preparing an oral impression, then pouring a model material into the oral impression to obtain a model which is completely consistent with the form of soft and hard tissues of the oral cavity, and finally preparing the dental restorations according to the model. The oral cavity impression is a female die of related tissues of the oral cavity and is used for reflecting the conditions of soft and hard tissues of the oral cavity related to restoration, whether the oral cavity impression truly reflects the conditions of the oral tissues or not is closely related to the accuracy of manufacturing the oral cavity restoration, and only if the accuracy of the oral cavity impression is ensured, the restoration with excellent quality can be manufactured.

As shown in fig. 7-8, an oral impression is prepared by preparing a negative impression of the tissue associated with the oral cavity with an oral impression material and an oral impression tray, which holds the oral impression material. The most widely used oral impression material in clinic at present is an alginate impression material, which is an elastic irreversible hydrocolloid impression material with high stability under the condition of 100 percent of humidity, and because hydrocolloid gel mainly consists of water, if the water content is increased or reduced, the volume of the impression material is changed, so that the stability of the dimension of the impression is affected; meanwhile, the viscosity of the hydrocolloid gel material is low, and when violent shaking, collision and extrusion are encountered, demolding can be caused.

When the prepared oral impression is transported, the prepared oral impression is mainly contained in a container such as a disposable oral examination tray or a disposable bending tray, and the like, as shown in fig. 7, and the prepared oral impression is sealed and stored by a disposable packaging bag. Thus, the oral impression has the following problems during transportation: the disposable packaging bag is soft in material, easy to deform, and incapable of effectively protecting the oral impression, and can be mutually extruded during transportation, so that the oral impression is deformed; the inability of the disposable oral examination tray or the disposable bending tray to fix the oral impression can cause the oral impression to move, collide, shake, etc., resulting in demolding or local deformation, so that the oral impression cannot reflect the actual situation of the soft and hard tissues of the oral cavity to be repaired, thereby affecting the accuracy and quality of the dental impression making prosthesis transported in this way.

According to the cleaning and disinfecting operation and management guidelines of the oral cavity impression and restoration of the medical institution in Guangdong province, the virus transmission caused by the nonstandard treatment of the impression and restoration is prevented, the disinfecting quality of the impression and restoration is ensured, and the medical safety and quality are ensured. The medical institution and the prosthesis processing institution should establish a safe transfer protocol for the impression and standardize the execution. At present, the packaging bag used for the oral cavity impression to be transported is soft in material, has no protective effect on the appearance of the impression, is easy to break, and can pollute the environment when the impression is exposed to the air (the oral cavity impression possibly has residual saliva or blood). And additionally, the packaging bag is additionally arranged, which is time-consuming and labor-consuming.

Therefore, the problem that the quality of the repairing body manufactured by the oral cavity impression is affected due to deformation and pollution of the impression caused by poor container holding during transportation of the oral cavity impression at present is solved, the number of times of re-diagnosis of a patient and the workload of doctors are increased, the medical quality is generally affected, and the satisfaction degree of the patient and the trust degree of the doctors and even hospitals are reduced. There is a need to develop an oral impression transfer cartridge to overcome the above-mentioned shortcomings and enhance the quality of oral impression transport.
