A dental implant was present in the position of tooth No. #33, whereas the other two implants previously placed posterior to this one had been extracted due to severe periimplantitis (Figure 1).
Teeth #43 and #48 were prepared according to the previously defined vertical dimension. A healing abutment was placed on the implant in position No. #33 after the removal of the cement-retained crown.

The metal framework carrying a unilateral custom tray at the edentulous area was tried intraorally. Impression of the edentulous area distal to the implant No. #33 was made with the framework in place so that an altered cast can be fabricated.

This area was filled with low-viscosity silicone, and the IARPD was seated to verify that adequate space was present for the activation (Figure 4).
The patient is in the maximum intercuspation position to ensure proper activation of the implant attachment. The activation insert was replaced by one with medium retentive force.
