Editor’s choice in February: the study of Verardi et al. on the osseointegration of tissue level implants placed in soft bone and with low primary stability.
Verardi S, Swoboda J, Rebaudi F, Rebaudi A. Osteointegration of tissue-level implants with very low insertion torque in soft bone: a clinical study on sla surface treatment. Implant Dent. 2018 Feb;27(1):5-9.
Study objectives: The present work tested the hypothesis that implants unstable at insertion could achieve osteointegration with proper implant surface treatment. Eleven Straumann tissue-level implants with sandblasted, large-grit, acid-etched (SLA) surface treatment were placed in soft bone unfavorable to primary stability, as indicated by insertion torque lower than 10 N/cm and slight mobility on the application of a lateral load of 250 g. After 4 to 6 months of healing, a reverse torque of 35 Ncm was applied to assess osteointegration.
Results and conclusions: 1. All implants appeared to be clinically osseointegrated and were successfully restored and loaded with fixed partial dentures or single crowns. After 28.5 months, all implants remained functional. 2. Within the limitations of the low number of implants analyzed, it can be concluded that tissue-level implants with sandblasted and acid-etched surface treatment can achieve osteointegration, even in the absence of primary stability.
