Screw Breakage and Loosening Problems in Implant Applications

Abutment screw fracture is one of the most common complications in implant applications. This problem, which is considered very important by dentists, can be solved by removing the broken screw or by making extra attempts on it. However, the aforementioned procedures cause the treatment process to be prolonged and painful for the patient. Screw fractures usually occur as a result of a higher load than normal, called occlusal trauma. This occlusal force can cause loosening of the screw inside the abutment. One of the main reasons for loosening is that the screw is not strong enough to withstand this resistance, but that the screw used is not compatible with the abutment. At this point, the abutment and screw used for the implant must be fully compatible with each other. The risk of screw loosening or breakage is reduced to a minimum as a result of occlusal trauma in screws and abutments that ensure the perfect fit. The screw, which is known to be compatible, is the key point of a perfect implant application by ensuring that the resistance is evenly distributed at all the points it contacts after it has been inserted in conformity with the geometric shape within the abutment.
