Comparison of implant - abutment breaking values

Implant treatment is used frequently and successfully in one tooth loss, partial and complete tooth loss. Despite the implant therapy's advantages, dentsits has some problems because of the mechanical and biological complications. This subject's aim is to see the breaking values of the implants and abutments and compare them. Totally 40 implants, abutmetns and screws are divided into 4 different groups. ISO 14801 standard is used and implants are placed with 30 degree angle to transition piece. 25 N torque moment is calibrated by using the company's implant devices. Instron Universal test machine applied an increasing force until the breaking happens with the speed of 8 mm per second. This process is applied to 40 implants one by one. Breaking values and breaking spotsa re saved. Datas are statistically evaluated by using student t test and oneway anova test. As a result, solid abutments' mean breaking value (2350 N) is higher than digital abutments' (1089 N). 4.5 mm platform diameter abutments' mean breaking value (1753 N) is higher than 3.5 mm platform diameter abutments' (1685 N).
