Outline of Final Research Achievements

Proper implant placement is very important for long-term implant stability. Recently, numerous biomechanical studies have been conducted to clarify the relationship between implant placement and peri-implant stress. However, few studies have used multiple analyses to clarify the value of offset placement under identical conditions. The present study aimed to clarify the biomechanical effects of offset placement on the peri-implant bone in edentulous posterior mandibles by comparative investigation using FEA and model experimentation with strain gauges.
The greatest stress and compressive strain was on the load side in all types of placements. Offset placement may not necessarily be more biomechanically effective than straight placement in edentulous posterior mandibles.
