Torque wrench for loosening of abutment screws (English)
Abstract [sv]

Underhåll av tandimplantat är tidskrävande och kan vara smärtsamt för patienten. Av denna anledning är det önskvärt att maximera tiden mellan återbesök. En faktor som påverkar återbesökstiden är hur mycket distansskruven i ett tandimplantat har lossnat med tiden. För att forska vidare på detta så behövs en momentnyckel som kan mäta det maximala momentet som krävs för att lossa distansskruven. För att uppnå detta har en systematisk produktutvecklingsprocess genomförts. Hållfasthetsberäkningar och FEM-analyser har genomförts för att se till att prototypens mekaniska egenskaper uppfyller de krav som ställs. För att framställa prototypen har 3D-skrivning använts, där mätningar, kalibrering och programmering gjorts för att säkerställa så momentnyckeln kan mäta det maximala momentet. Arbetet resulterade i en prototyp av kolfiberkomposit och titan för att mäta det maximala momentet som krävs för att lossa en distansskruv.

Abstract [en]

Maintenance of dental implants is time-consuming and can be painful for thepatient. For this reason, it is desirable to maximize the time between return visits. One factor that affects the revisit time is how much the abutment screw in a dental implant has loosened over time. In order to further research on this, a torque wrench is needed that can measure the maximum torque required to loosen the abutment screw. To achieve this, a systematic product development process has been carried out. Strength theory calculations and FEM analyses have been carried out to ensure that the prototype's mechanical properties meet the requirements. To produce the prototype, 3D printing has been used, measurements, calibration and programming has been done to ensure that the torque wrench can measure the maximum torque. The work resulted in a prototype made of carbon fiber composite and titanium for measuring the maximum torque required to loosen a abutment screw.
