Multicenter randomized clinical trial: early loading of implants in maxillary bone.

Purpose: The aim of this study was to show prognostic equivalence between implant loading in the maxilla after 12 weeks versus 4 weeks.

Materials And Methods: One hundred four patients, from four centers in this open-labeled randomized multicenter prospective controlled clinical trial, were assigned to either 12 weeks or 4 weeks of unloaded healing. Two hundred sixty-nine implants (sand blasted large-grid, acid etched [SLA] surface, ≥ 4.

Early loading of sandblasted and acid-etched titanium implants in the edentulous mandible: a prospective 5-year study.

Purpose: The aim of this prospective cohort study was to determine the 5-year implant survival and success rates associated with early loading (6 weeks after nonsubmerged placement) of sandblasted and acid-etched (SLA) Straumann implants in the edentulous mandible. A secondary objective was to determine the peri-implant tissue response and measure alterations in peri-implant crestal bone levels.

Materials And Methods: SLA implants were placed and primarily loaded 6 weeks later with 35 Ncm during abutment placement.
