Full-arch rehabilitation of an upper jaw with 6 GTB Tzero implants

The decision to perform a full rehabilitation of a dental arch forces us to make other importantdecisions regarding the management of osseointegration, soft tissue and hard tissue.In this specific case, our focus was on maintaining masticatory parameters, vertical dimensionand soft tissue stability.The 75-year-old patient was rehabilitated with a full arch prosthesis screwed into the upperarch, choosing a deferred-loading implant. 

Two types of provisional restorations were thenmade, the first for dental support, pending the integration of the implants, and the secondfor implant support.The permanent prosthesis screwed onto the GTB Tzero implants was made using compositematerials and a glass fibre framework.

The decision to perform a full upper arch rehabilitation with deferred-loading implants was dictated by the fact that the patient inquestion still had some strong teeth that could support a temporarymasticatory load and give us the possibility to better manage hardand soft tissues.Primary stability during implant placement is decisive for the decisionto perform immediate loading or deferred loading once osseointegrationhas taken place.A 75-year-old man came to us with a partially decemented fixed prosthesison the upper arch and a fractured metal framework.
