Problems solved by technology

[0003] At present, commonly used impression materials in clinical practice, such as alginate, silicone rubber, polyether, polysulfide rubber, etc., cannot obtain the dynamic (functional state) of the soft palate defect area due to the fast solidification speed or too strong fluidity of these materials in the mouth. impression

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0024] The novel mouth-temperature shaping wax (hereinafter referred to as the mouth-temperature wax) developed by the present invention requires that it should have good biological safety, become soft and moldable but not flow at the temperature of the mouth, and be hard and stable in shape at room temperature. This ensures that the impression of the soft palate defect area is not deformed.

[0025] 1. Formula screening and development of mouth temperature shaping wax

[0026] The main factors affecting the softening point of wax are as follows:

[0027] (1) It is related to molecular weight. Waxes composed of different molecular weights have different softening points. Generally speaking, as the molecular weight increases, the softening point will increase accordingly;

[0028] (2) It is ...

Abstract

The invention discloses an oral-temperature shaping wax used for preparing a soft palate defect cavity impression and a preparation method thereof, belonging to the technical field of medical materials used for the oral cavity. The oral-temperature shaping wax comprises, by mass, 45 to 55% of paraffin, 25 to 35% of mixed crystalline wax, 8 to 15% of microcrystalline wax, 5 to 10% of rosin and 1 to 5% of polypropylene. The oral-temperature shaping wax disclosed in the invention has good biosecurity, becomes soft and shapable at oral temperature without becoming flowable, and is hard and stable at room temperature. The preparation method for the oral-temperature shaping wax is simple to operate, is green and environment-friendly and is applicable to industrial large-scale production.

Description

technical field [0001] The invention belongs to the technical field of oral medical materials, and relates to an oral temperature shaping wax used for making impressions of soft palate defect cavities and a preparation method thereof. Background technique [0002] Soft palate defect is a common type of maxillofacial defect in clinical practice. Because the defect destroys the velopharyngeal closure structure, the patient's diet will leak out through the nasal cavity, and they will not be able to swallow food normally. The repair method of soft palate defect mainly adopts occluder repair. In the occluder repair of soft palate defect, due to the special anatomy and function of the defect site, it is necessary to make an impression of the functional state of the defect area (such as swallowing, pronunciation, etc.). There is a need for an impression material that remains plastic and does not flow for a long time in the oral cavity. It is hoped that the material will always mai...
