Characteristics of implant surface and implant-abutment gap in two- and one-stage systems

| Sumario: | The aim of this study was to evaluate under scanning electron microscopy the characteristics of the implant surface and the gap between the components of two- and one-stage systems. Three two-stage implants coated with RBM and three one-stage implants coated with TPS were selected. In the two-stage implants, the esthetic-cone abutments were adapted and screw tightened with 20 N/cm . In the one stage implants, solid abutments were adapted and torque tightened mechanical frictional with 30 N/cm. The specimens were mounted on stubs and analyzed under scanning electron microscopy. The gap in each implant was measured in four different points and repeated three times. The paired Student-t test was applied to detect the difference in the gap extension. The results showed that no significant differences (P >; 0.05) were found regarding the gap extension between two- and one-stage systems and that the treatments produced different surface roughness. |
