Description

Denture removing device and denture removing assembly

Technical Field

The application relates to the technical medical appliance field, in particular to a false tooth removing device and a false tooth removing assembly.

Background

When the teeth are damaged due to trauma or caries, the teeth not only have influence on the external appearance of people, but also have certain negative effects on daily life behaviors such as chewing, speaking and the like. For such a defective tooth, a dentist usually prepares various types of dentures to restore the appearance thereof, such as a coping, a bridge, a post-core crown, etc., and finally adheres the denture to the surface of the abutment using an adhesive. When special conditions such as abutment pain, porcelain collapse or influence nuclear magnetic resonance and the like need to be removed, a patient cannot take the adhesive out of the abutment by himself usually due to the use of the adhesive, and the adhesive can be removed by a doctor through the combined use of instruments such as a high-speed turbine handpiece, a crown remover and a dental elevator.

The clinically common denture removal procedure: firstly, a high-speed turbine mobile phone and a carborundum machine needle act on the surface of the false tooth to cut the false tooth into two parts, the depth is until an adhesive is seen, then a dental elevator is inserted into a seam to slightly rotate and elevator until the dental crown is observed to be loosened, finally the edge of the crown is hooked by a traditional crown remover, and the dental crown is vibrated and shed from the surface of the abutment by using impact force generated by impact of a sliding hammer. However, this solution has significant drawbacks: 1. the dental implant needs to be matched with a high-speed turbine handpiece and a carborundum needle, the depth is difficult to control during cutting, and excessive grinding of tooth tissues and even injury to dental pulp nerves are easy to occur; 2. the operation difficulty of the dental elevator or the crown remover is high, the force is difficult to control, and the abutment is easy to be damaged and cracked or loosened; 3. the crown remover or the tip of the dental elevator is of a blade-shaped structure, so that a doctor needs to make an intraoral fulcrum with hands when using the dental crown remover or the dental elevator, otherwise the dental crown remover or the dental elevator is easy to slip off to cause mucosal injury, and the pain of a patient is increased; 4. the mechanical impact sound produced by the crown remover and the sound of the high speed turbine handpiece tend to increase the patient's fear of dentistry.
