Eksperimentel: implant placement
insertion of 2 interforaminal mandibular implants and conversion of the lower complete denture to an implant-overdenture
|
Participants received two Straumann Standard Implants® in the interforaminal region using the recommended surgical protocol.
The implants were loaded using Locator® attachments after six to eight weeks healing time by transforming the existing lower denture to an IOD.
