Long-term complications are related to factors in the patient and others to technology. There are risks associated with the appearance, including the shape of the smile, poor quality of the gums such as retraction or loss, difficulty in matching the shape of the natural teeth and other times. Orthopedic or not brushing teeth, which results in poor oral hygiene, which affects the success of implants. [43]
Risks can be related to biomechanical factors, where the geometry of dental implants is different from natural teeth in terms of support, such as when there are extensions of the denture that are not centered on one side, or when the implants have fewer roots or teeth they replace (or when they are The crown-to-root surface ratio is low. Similarly, bruxism, bone deficiency or low diameter implants increase biomechanical risks. Finally, there are technological risks, as the implants themselves can fail due to fracture or loss of adherence to the teeth to be supported.[4]
