A Prospective Multicenter Clinical Trial Comparing One‐ and Two‐Stage Titanium Screw‐Shaped Fixtures with One‐Stage Plasma‐Sprayed Solid‐Screw Fixtures

Cumulative survival rates for MS fixtures placed in one and two stages as well as one-stage TPS screws up to the 2- to 3-year follow-up examination were similar, indicating excellent clinical results. Radiographic measurements for changes in crestal bone loss were clinically insignificant for fixtures placed in one stage. For two-stage fixtures, maxillary changes were insignificant, whereas mandibular bone loss was statistically significant but clinically insignificant. Changes in crestal bone loss for TPS implants were statistically significant.
