Compact structure, convenient measurement of the angle between the line of the crest of the upper and lower jaw alveolar ridges and the occlusion plane, simple use and convenient guidance of tooth arrangement.
Description
Technical Field
The invention relates to an alveolar ridge angle measuring instrument for upper and lower jaws and a using method thereof.
Background
Dentition loss is a common disease for elderly patients, while complete denture repair is a common repair mode for dentition loss patients. With the development of complete denture repair technology and materials, the clinical fabrication of complete dentures has tended to be simplified and streamlined. The complete denture is manufactured by mainly 3 key steps, namely impression, jaw position relation determination and tooth arrangement, wherein the reasonable degree of tooth arrangement is closely related to the stability and comfort after the complete denture is manufactured.
The complete denture can be partially repaired by patients who wear the complete denture and then have the problems of denture tilting, poor retention force, soft tissue tenderness and the like, which probably is that the traditional denture is not reasonably arranged according to the conditions of the alveolar ridge during tooth arrangement, so that the complete denture is poor in stability after being manufactured, and the denture tilting is caused in the chewing process, so that mucous membranes are pressed and pressure pain exists. Therefore, reasonable tooth arrangement is required according to the condition of the alveolar ridge during tooth arrangement, so that resultant force generated by the false tooth is vertically transmitted to the alveolar ridge, and the burden of the alveolar ridge is reduced.
According to the requirement, from the frontal section of the posterior dental area, if the angle formed by the connecting line of the upper alveolar ridge and the lower alveolar ridge and the joint plane is more than 80 degrees, the relationship between the upper jaw and the lower jaw is considered to be normal, and the normal cuspate contact relationship can be arranged. When the intersection angle between the line of the upper and lower alveolar ridges and the plane is 80 degrees or slightly smaller, the upper and lower alveolar ridges can still be arranged in a normal position, but the upper posterior teeth can still be arranged in a normal position if the posterior teeth are covered by the lower posterior teeth, the functional cusps are arranged on the line of the alveolar ridge tops, the lower posterior teeth can be arranged in a buccal direction slightly, and the fossa lingualis is widened. When the intersection angle of the connection line of the upper and lower alveolar ridges and the occlusal plane is obviously smaller than 80 degrees, namely the lower arch is wider than the upper arch, the posterior teeth need to be arranged in a contra-occlusion relationship.
