Resumo


Purpose: This study aimed to evaluate the influence of tomographic acquisition parameters (mAs and kV) from different devices on the identification and classification of peri-implant angular bone defects. Material and methods: Dental implants were placed in bovine ribs, and angular defects were surgically created in the cervical region of the implants using burs. Tomographic acquisitions were performed using two different CBCT devices (Accuitomo 170 and OP300). For each system, two distinct acquisition protocols were employed: Accuitomo 170 - ProtA1 (90kV, 8mA, 4x4 FOV) and ProtA2 (90kV, 7mA, 4x4 FOV); OP300 - ProtO1 (90kV, 12.5mA, 5x5 FOV) and ProtO2 (90kV, 6.3mA, 5x5 FOV). Results: The identification of peri-implant angular bone loss was satisfactory for both devices. ProtO1 and ProtO2 showed no significant difference in the identification of peri-implant angular bone defects. However, ProtA1 allowed for superior visualization of the types of peri-implant angular bone defects compared to ProtA2. Conclusion: It can be concluded that the tomographic acquisition protocol can directly interfere with the ability to identify the specific type of peri-implant angular bone defect.
