Final answer:
Fixed partial dentures (FPD) and removable partial dentures (RPD) can be attached to the maxilla using precision attachments and connectors. The attachments are placed on the abutment teeth of the FPD, and the connectors are custom-made to fit the design of the FPD and RPD.
Step-by-step explanation:
When attaching a fixed partial denture (FPD) and a removable partial denture (RPD) to the maxilla, there are different methods that can be used. One common method is to use attachments called precision attachments or semi-precision attachments. These attachments provide a secure and stable connection between the dentures and the maxilla.
For the FPD, the attachments are usually placed on the abutment teeth, which are the teeth that support the FPD. These attachments can be in the form of crowns, bridges, or implant-supported crowns. They are designed to fit precisely into the corresponding attachments on the FPD, ensuring a tight and stable fit.
On the other hand, the RPD is usually attached to the FPD using metal or acrylic connectors. These connectors are custom-made to fit the specific design of the FPD and RPD and provide a secure connection between the two. The connectors are usually placed on the lingual or buccal surface of the FPD, depending on the design.
