In vivo analysis of active versus self-tapping implants with SLA surface treatment

Abstract

Surface modifications and implant thread designs play a crucial role in achieving primary stability and osseointegration. Therefore, it is of interest to compare the short-term clinical and radiographic outcomes of active versus self-tapping titanium implants with sandblasted, large-grit, acid-etched (SLA) surfaces in 20 systemically healthy patients requiring posterior implant-supported prostheses. Clinical and radiographic parameters were assessed at 4, 7, 12 and 26 weeks and statistical analysis showed significant intra-group improvements in probing depth, attachment levels, mucosal margin stability and bone gain. However, intergroup comparisons at all-time points revealed no statistically significant differences, indicating comparable performance between the two implant designs. Overall, both active and self-threaded SLA implants demonstrated favorable short-term clinical outcomes, supporting their effectiveness in promoting early osseointegration and potential use in early loading protocols.
