Example Embodiment
[0052] Example 1,
[0053] A complete denture includes a maxillary denture and a mandibular denture. Both the upper and lower dentures are provided with a base and artificial teeth.
[0054] The base part of the maxillary denture includes the upper alveolar crest area and the palatal side area of the upper alveolar crest. The artificial teeth are arranged in the base part of the upper alveolar crest area. The horizontal projection of the upper alveolar crest area is curved. , The palatal area of the alveolar ridge crest is located in the curved area of the upper alveolar crest area; the base part of the upper alveolar crest area facing the oral vestibule is made of silicone rubber; figure 1 , 2 , 5 shown.
[0055] The base part of the mandibular denture includes the inferior alveolar ridge crest area and the posterior molar area. The artificial teeth are arranged in the base part of the inferior alveolar ridge crest area. The horizontal projection of the lower alveolar ridge cr...
Example Embodiment
[0057] Example 2,
[0058] A complete denture whose structure is as described in Example 1. The difference is that one third of the proximal end of the pad area after the molar is made of silicone rubber, such as image 3 , 4 .
Example Embodiment
[0059] Example 3.
[0060] A complete denture whose structure is as described in Example 1, except that the connecting surface of the base part made of silicone rubber and the base part made of non-silicone rubber is connected by a concave-convex head, and the base made of silicone rubber Part of the connecting surface is provided with grooves, and the connecting surface of the base part made of non-silicone rubber is provided with bosses, such as Figure 7 As shown, the groove and the boss are matched and connected. The boss is a rectangular body, the groove is a rectangular groove, the boss is provided with a cylindrical through hole, the cylinder axis is parallel to the connecting surface; the groove is correspondingly provided with a cylindrical cylinder, and the cylindrical cylinder is located in the cylindrical through hole. After hot compression molding, the cylindrical cylinder located in the cylindrical through hole is integrated with other surrounding silicone rubber, s...
