Changing the flute design affects initial dental implant stability: Study
Changing the flute design affects initial dental implant stability, according to a recent study published in the journal named- Clinical Biomechanics.
Self-tapping screws have been extensively used for dental implants. Their biomechanical behaviour is highly associated with their clinical success, particularly for screws used for immediate implant placement and restoration, because occlusal forces can directly affect the loading transfer at the bone-implant interface after implantation. The effect of implant design on the initial stability of self-tapping screws remains unclear. This study explored the biomechanical behaviours of implant stability in standardized implants with different design features.
Six types of dental implants were designed using computer-aided design/computer-aided manufacturing technology, including three types of cutting flute shapes (spiral, straight, and non–self-tapping) combined with two types of screw features. Peak insertion torque values were first recorded; initial stability levels were subsequently evaluated in terms of the maximum force and resistance to lateral loads using an electrodynamic test system.
