Embodiment 1

[0031] A method for making a closed mouth impression of a complete denture, the steps are as follows:

[0032] ⑴Take the initial impression, perfuse the initial impression to make the initial model: use the alginate impression material to obtain the initial impression of the upper and lower edentulous jaws of the patient, pour the initial impression with ordinary plaster, and after the plaster hardens, reproduce the initial model

[0033] ⑵ Make a temporary base and individual trays on the initial model: Use base wax to buffer the upper and lower jaw undercuts and hard areas, and use temporary base materials to make temporary bases and individual trays. The temporary base material is a photocurable base resin material

[0034] ⑶ Make a wax embankment on the temporary base and individual trays, and conduct a test occlusion in the patient's mouth to determine the relationship between the upper and lower jaws;

[0035] ⑷Paste the edge plastic material on the edge of the temporar...

Embodiment 2

[0043] A method for making a closed mouth impression of a complete denture, the steps are as follows:

[0044] The finished edentulous tray was used to take the alginate impression material, and the upper and lower edentulous initial impressions were taken by the traditional open-mouth impression method, and the ordinary plaster model was reproduced. Use room temperature curing denture base resin to make a temporary base, try on the temporary base in the oral cavity, and trim the edge height of the base, generally 1 mm to 2 mm from the gingiva-labial and buccal sulcus. Cheek and lingual frenulum. Make a wax embankment on the temporary base, and accurately record the vertical distance and cusp staggered position; paste the edge plastic material on the edge of the temporary base, introduce it into the patient's mouth, and guide the patient to perform edge shaping to complete the edge shaping After the molding work, take out the temporary base with the wax embankment and the edg...

Abstract

The invention relates to a method for preparing a complete denture closed impression from a novel edge trimming and shaping material.The method comprises the following steps that an initial impression is taken and filled, and an initial model is made; a temporary base tray and individual trays are made on the initial model; bite blocks are made on the temporary base tray and the individual trays, and trial biting is carried out to determine the upper and lower jaw position relation; the edge trimming and shaping material is bonded to the edge of the temporary base tray, the temporary base tray is led into the mouth of a patient, and the patient is guided to carry out initiative edge trimming and shaping.Inorganic filler is added into the edge trimming and shaping material and can improve the strength of the material; the inventor finds through practical use that the strength of an existing material is slightly poor, the shape maintaining effect is not good and slight deformation exists after the existing material is cooled to the room temperature, after deformation, the fitting degree of denture bases and the edge soft tissue thereof is likely to be decreased, and the edge sealing effect is weakened.

Description

technical field [0001] The invention relates to the field of complete denture production, in particular to a method for preparing a closed-mouth impression of a complete denture by using a novel edge plastic material. Background technique [0002] The closed-mouth impression is taken with the patient's mouth closed. Since there is no external human interference, the closed-mouth impression can better reflect the real edentulous tissue impression of the patient's oral function state. However, due to the complicated clinical operation and high technical requirements of the closed impression, it is generally used in the relining of complete dentures and the duplication of complete dentures. When the edentulous condition is poor, the quality of the impression is particularly important for the final complete denture restoration. In particular, the edge extension of the denture, the buffering of the ligature, the sealing of the edge, and the closeness of the complete denture to t...
