Brånemark Novum Immediate Loading Rehabilitation of Edentulous Mandibles: Case Series with a 16-Year Follow-up.

The aim of the present report was to evaluate the clinical outcomes of edentulous jaws rehabilitated with the Brånemark Novum protocol over a 16-year period. Between April and November 2001, four patients (three males, one female) were rehabilitated with fixed full-arch rehabilitations supported by three immediately loaded implants following the Brånemark Novum protocol. Cumulative survival rates (CSRs) of the implants and prosthesis, bleeding on probing (BOP), Plaque Index (PI), probing depth (PD), implant stability quotient (ISQ; as measured through resonance frequency analysis [RFA]), and peri-implant bone resorption were evaluated over time, up to the 16-year follow-up. At 16 years of follow-up, no implant failed (CSR 100%) and no prosthesis needed to be substituted (CSR 100%). During the period between the 11th and 16th year of follow-up, bone level (mean: 2.2 mm at 16 years) and RFA values remained stable. At the 16-year follow-up, the implants presented high PI (79.2%) but low BOP (10.4%) values. Mean PD was 3.30 mm (range: 2 to 6 mm). One biologic complication was detected on a central implant (crater-form bone destruction), and several prosthodontic complications occurred during the 16 years (fractures of resin or teeth), the majority of which were registered on the same parafunctional patient. This is the first description of the Brånemark Novum protocol rehabilitation with a 16-year follow-up. The outcomes demonstrated very good long-term outcomes for this protocol.
