Technical Field
The utility model belongs to oral cavity maxillofacial surgery medical instrument field, concretely relates to rotatory wicresoft of upper jaw molar forceps.
Background
Dental extraction is the most basic and common procedure in oromaxillofacial surgery. Dental forceps are the preferred tool for performing tooth extractions. The quality of the tooth extraction forceps is an important factor influencing the tooth extraction efficiency. The tooth extracting forceps can be divided into an upper front tooth forceps, a lower front tooth forceps, an upper front tooth grinding forceps, a lower front tooth grinding forceps, an upper tooth grinding forceps and a lower tooth grinding forceps according to tooth anatomical forms. The upper molar is positioned in the far middle of the upper premolar and is a type of tooth with the largest volume of the crown and the most complex shape in the permanent tooth. Most of the upper molar teeth have three roots, the roots are thick and the root branches are large. Therefore, when the upper jaw molar is pulled out by using the dental forceps, a large clamping force is needed, the upper molar forceps is required to have a strong rigidity performance, and meanwhile, the form design of the dental forceps is reasonable, so that the upper jaw molar dental crown can be conveniently clamped.
The current upper jaw grinding tongs cross section is great, and the pincers beak is thick, though has certain rigidity, however when centre gripping upper jaw grinding, because the nearly buccal side space of upper jaw grinding is little, current upper jaw grinding tongs beak top can't laminate whole dental crown, easy slippage to the biggest efficiency that can't exert dental forceps leads to extracting the tooth efficiency lower, hardly once only extracts the grinding tooth. In addition, because the existing molar forceps have thicker beak and are easy to damage surrounding soft tissues and adjacent teeth, the pain of patients is brought, and the working strength of doctors is increased.
