Primary | change of alveolar bone level | The primary outcome of the study was a change in alveolar bone level (height in mm) at the 40 implant site between T0 and T2 months after surgery measured on CBCT. All measurements were performed at four sites (mesial, distal, buccal, and lingual) around each dental implant at T0 and T2. These four values were then averaged for each dental implant. Alveolar bone level were measured in millimeters (height in mm) from a fixed reference point on the implant (implant shoulder to the most coronal position of the crestal bone contacting the implant). |
0 and 6 month | |
Secondary | changes level of IL-1ß | The secondary outcome of the study was change the level of IL-1ß pg/ml between T0, T1, and T2. To obtain PICF, filter paper strips were gently inserted into the peri-implant crevice for 30 s at the mesial, distal, buccal, and lingual sites of the dental implant. A Williams periodontal probe was used for all clinical measurements.These parameters were recorded for evaluating the clinical status of the dental implants. All measurements were performed at four sites around each dental implant. For the statistical analysis, median of the four measurements at each implant was used. The level of IL-1ß pg/ml (weight in picogram, weight in milliliter) |
0, 3, and 6 month | |
Secondary | changes of PPD | The secondary outcome of the study was change of the PPD between T0, T1, and T2. A Williams periodontal probe was used for all clinical measurements.These parameters were recorded for evaluating the clinical status of the dental implants. All measurements were performed at four sites around each dental implant. For the statistical analysis, median of the four measurements at each implant was used. Probing pocket depth (PPD) (depth in mm), were measured |
0, 3, and 6 month | |
Secondary | changes of Modified plaque index | The secondary outcome of the study was change of the Modified plaque index between T0, T1, and T2. A Williams periodontal probe was used for all clinical measurements.These parameters were recorded for evaluating the clinical status of the dental implants. All measurements were performed at four sites around each dental implant. For the statistical analysis, median of the four measurements at each implant was used. Modified plaque index (0=no plaque, 1= mild plaque, 2= moderate plaque, 3=severe plaque). |
0, 3, and 6 month | |
Secondary | changes of Modified gingival index | The secondary outcome of the study was change of the Modified gingival index between T0, T1, and T2. A Williams periodontal probe was used for all clinical measurements.These parameters were recorded for evaluating the clinical status of the dental implants. All measurements were performed at four sites around each dental implant. For the statistical analysis, median of the four measurements at each implant was used. Modified gingival index (0=healthy, 1=mild inflammation 2= moderate inflammation 3=severe inflammation). |
0, 3, and 6 month | |
Secondary | changes of Modified bleeding index | The secondary outcome of the study was change of the Modified bleeding index between T0, T1, and T2. A Williams periodontal probe was used for all clinical measurements.These parameters were recorded for evaluating the clinical status of the dental implants. All measurements were performed at four sites around each dental implant. For the statistical analysis, median of the four measurements at each implant was used. Modified bleeding index (0= no bleeding, 1= mild bleeding, 2= moderate bleeding, 3=severe bleeding). |
