BACKGROUND: Evidence shows lower chance for osseointegration of implants without sufficient primary stability. The present retrospective study observed bone level conical screw implants with textured surface without primary stability.
METHODS: Twenty-six Stark conical screw implants, with V-Blast (Vanish Blast) surface treatment were placed with low primary stability, (insertion torque lower than 10 N/cm and visible mobility at lateral load of 250 g). A soft diet was prescribed. osseointegration was assessed applying 30 Ncm of reverse torque 6 months after placement.
RESULTS: The 26 implants that did not achieve primary stability still had a survival rate of 96% after the observation period and were classified as successful according with ICOI Pisa consensus conference success, survival, failure classification .96% of the implants showed clinical osteointegration and were successfully restored. After 12 months, all implants remained functional.
CONCLUSIONS: It can be concluded that bone-level implants with V-Blast surface in absence of functional loading are able to achieve osteointegration, even with low primary stability.
