### Evaluation of Peri-Implant Marginal Bone Loss  
The marginal bone loss at the time of taking an impression for a prosthesis (T1), and 12 months after the prosthesis (T2), was measured based on the time immediately after implant placement (T0). At the time of T1, the marginal bone loss of 41 implants was measured, and the marginal bone loss of 36 implants with the final prosthesis at the time of T2. In T1, marginal bone loss was observed to be an average of 0.16 mm compared to T0,
