A kind of semi-finished complete denture based on prefabricated dentition structure and the rapid manufacturing method of complete denture

Abstract

The invention provides a semi-finished complete denture based on a prefabricated dentition structure and a rapid production method of the complete denture, aiming at reducing the workload of dentists and technicians and reducing the waiting time of patients under the premise of accurately fitting the patient. The semi-finished complete denture includes a prefabricated temporary base of thermosetting resin material and a prefabricated dentition fixedly combined with it; the prefabricated temporary base is provided with a plurality of strip-shaped holes, and the width of the hole on one side of the polished surface is Slightly larger than the width of the orifice on one side of the tissue surface; the strip-shaped holes in the palatal area of ​​the preformed temporary base of the upper jaw are symmetrically distributed on the left and right, and both ends of the length direction are closed; One end on the top reaches the edge of the preformed temporary base, forming an opening on the edge of the preformed temporary base, and the other end is closed; the distance between the lip-palatal (tongue) and buccal-palatal (tongue) of the preformed temporary base tissue surface is slightly It is greater than the distance between the corresponding parts of the clinical complete denture tissue surface to replace the role of the impression tray and reserve a space for the impression material.

Description

Technical field [0001] The present invention relates to a rapid production method of full dentures. Background [0002] as Figure 1 As shown, the surface structure of a full denture can be divided into three parts, namely the tissue surface 1, the polished surface 2 and the occlusal surface 3. [0003] Tissue Surface is the surface where the denture base is in close contact with tissues such as the alveolar crest and palate under its coverage. The area of tissue under the base cover is called the Denture Bearing Area, and the load on the denture when it functions is transmitted through the tissue surface to the supporting tissue. The tissue surface is also the main part where the denture gains a fixation. [0004] Polishing surfaces, also known as polished surfaces, are surfaces where dentures come into contact with soft tissues and muscles on the lips, cheeks, and lingual sides, such as those Figure 2 as shown. The polished surface should form an appropriate concave bevel so t...

Problems solved by technology

[0008] However, in clinical practice, most patients often cannot achieve the occlusal position of the upper and lower teeth at one time and satisfy the patient's facial aesthetics. It is often necessary to go back and forth between the clinical clinic and the denture processing factory repeatedly to re-upper the jaw frame and re-fit the denture. Arrange the teeth, try them repeatedly until the occlusal relationship is correct, and the shape of the dentures satisfies the patient, then the filling and grinding can be completed

The entire process takes several days, and the process is numerous and time-consuming
