Reduced Diameter Implants - A Long Term Follow-Up

The success rate of 327 Straumann Bone Level implants with diameter of 3, 3 mm was observed for a period of one to six years. At the control visit the following were registered absence or presence of exudation, bleeding on probing and marginal bone resorption visible on radiography, and survival rate. The survival rate of the implants with reduced diameter was 98, 2 %. Bleeding on probing was registered in 18, 7 % of the cases. The mean marginal bone resorption was 0, 137 in the cases without registered bleeding on probing, and 0, 705 in the cases where bleeding on probing was observed.
