One of the possible choices of restoring missing teeth is removable partial denture, especially when fixed restorations are not indicated or not feasible. Removable dentures can be attached for retention and support to the natural remaining teeth by conventional connectors(retentive-stabilising-resting arms, hooks).
In some cases, when crowning of the abutment teeth is indicated
the denture can be attached to those crowns by different precision attachments, which mechanically and cosmetically are advantageous in comparison with the regular connectors. These are the precision attachment combined cases.
Some patients are completely edentulous or at least couple teeth can be saved on the lower jaw. In such cases the upper complete denture can be constructed, which usually is sufficiently retentive, and the lower remaining teeth can be root canal treated, restored with special posts and connected to the lower denture for retention with special attachments.
In the case of complete lower edentulism minimally two implants with attachments for retention of the lower denture are recommended.
