The anchor-type attachment is placed on the collar, lip or bar of the abutment, which needs less space and less elastic cushion for gingival space, suitable for unilateral/bilateral calcium deficiency and implant-supported overdentures (unilateral calcium deficiency should be supported on the opposite side)The hammer-like structure of the attachment creates a mechanical retention force between positive and negative retainers. The positive retainers with different retentions can be replaced for single/bilateral free deficiency and partial deficiency repair
Advantages: The steel denture has high strength and hardness, even if the thickness of the denture base is less than 1 mm,the steel denture feels comfortable in the mouth, the support strength and hardness are obviously better than the traditional Resin denture base, which is the mainstream material of the removable denture at present
