Abstract:
OBJECTIVETo determine ITI implants stability in different bone types using RFA and to provide evidence for feasibility of early loading.
METHODSA total of 104 ITI sand-blasted large-grit acid-etched (SLA) implants in 50 patients were classified into 3 groups according to bone type. Resonance frequency analysis was conducted at 0, 1, 4, 6, 8 and 12 weeks after installation.
RESULTSThe survival rate was 100%. Primary stability was affected by bone type (P < 0.001). The implant stability quotient (ISQ) was significantly higher in type I bone than in type IV bone. At 12 weeks, there was no significant difference among the 3 groups. Comparison of ISQ was made between 6 th week and 12 th week for all bone types, there was no significant difference for type I and III (P > 0.05) while there was for type IV (P < 0.001).
CONCLUSIONSEarly loading with ITI SLA implants placed in type I, III bone were highly predictable.
