| 摘要 |
<p>Dentures of the present invention include opposing upper (12) and lower (14) dentures and have at least one pair of opposing posterior upper (36) and posterior lower (15) teeth. Each posterior upper artificial tooth (36) is formed from a resilient material, preferably an acrylic material, and has a substantially flat masticating surface. Each posterior lower artificial tooth (50) has a single longitudinal crest (82) formed along the length of its masticating surface. An elongated metal blade (62) is embedded in each posterior lower artificial tooth (50) with a longitudinal edge of the metal blade lying flush with the longitudinal crest (82). The dentures are manufactured by aligning the metal blade (62) and longitudinal crest (82) of each posterior lower artificial tooth (50) substantially parallel with and overlying the apex of denture wearer's mandibular ridge and by aligning each opposing posterior upper artificial tooth (36) substantially parallel with and centrally overlying the denture wearer's maxillular ridge.</p> |
