Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Processo FAPESP: 07 53293-4 Purpose: The objective of this in vitro study was to quantify the strain development of external hexagon. and internal hexagon implant-supported partial prostheses in. straight and offset implant placement configurations.Materials and Methods: Three external hexagon and 3 internal hexagon. implants were embedded in the center of each polyurethane block. Four strain gauges were bonded on the surface of polyurethane. The 20 superstructure occlusal screws were tightened onto the Microunit abutments with a torque of 10 Ncm using the manufacturer's manual of torque-controlling device.Results: There were statistic significant differences in hexagonal ope (P = 0.0210 < 0.05). There were no statistic significant differences in placement configuration (P = 0.7483 > 0.05). The results showed fundamental differences between both conditions.Conclusion: Under the limited conditions of this study the hexagon internal connection displayed higher values of microstrain. than the hexagon. external type implant placement. There was no evidence that there was an advantage of offset placement in reducing the strain around implant. There was no proof from this investigation that the straight placement generated higher microstrain than offset placement. (Implant Dent 2009;18:512-520) |
