Временное ограничение |
---|---|---|
Marginal Bone Level Alteration
Временное ограничение: Evaluated from implant installation to 12 months after implant loading
|
Marginal Bone Level determined from radiographs and expressed as the difference from a reference point on the implant to the most coronal bone-to-implant contact on the mesial and distal aspect of the implant, and expressed in millimeters. Marginal Bone Level change calculated from values obtained at delivery of permanent restoration i.e. loading of implants (baseline) compared to the values obtained at the follow-up visit 12 months after loading. Positive value = bone gain, Negative values = bone loss. |
Evaluated from implant installation to 12 months after implant loading

Marginal Bone Level Alteration After 36 Months
Временное ограничение: Evaluated from implant loading to 36 months after implant loading.
|
Marginal Bone Level determined from radiographs and expressed as the difference from a reference point on the implant to the most coronal bone-to-implant contact on the mesial and distal aspect of the implant, and expressed in millimeters. Marginal Bone Level change calculated from values obtained at delivery of permanent restoration i.e. loading of implants (baseline) compared to the values obtained at the follow-up visit 36 months after loading. Positive value = bone gain, Negative values = bone loss. |
Evaluated from implant loading to 36 months after implant loading.
|
Implant Survival
Временное ограничение: Evaluated from implant installation to 36 months after implant loading.
|
Implant survival rate evaluated clinically and radiographically.
|
Evaluated from implant installation to 36 months after implant loading.
|
Implant Stability
Временное ограничение: Evaluated 36 months after implant loading.
|
Implant stability evaluated clinically/manually (recorded as stable yes/no).
|
Evaluated 36 months after implant loading.
|
Condition of the Periimplant Mucosa (PPD).
Временное ограничение: Evaluated from implant loading to 36 months after implant loading.
|
Condition of the periimplant mucosa measured by assessment of probing pocket depth (PPD). Change in pocket depth expressed in millimeters at the 36 month follow-up visit compared to values obtained at delivery of permanent restoration i.e. loading (baseline). Negative value = increased pocket depth |
Evaluated from implant loading to 36 months after implant loading.
|
Condition of the Periimplant Mucosa (BoP).
Временное ограничение: Evaluated from implant loading to 36 months after implant loading.
|
Condition of the periimplant mucosa will be measured by assessment of bleeding on probing (BoP). Presented as % of the implants that show presence of bleeding at time of the 36 months follow-up. |
Evaluated from implant loading to 36 months after implant loading.
|
Plaque
Временное ограничение: Evaluated 36 months after implant loading.
|
Occurence of plaque around the study implant.
Presented as proportion of implants that showed presence of plaque at the 36 months follow-up visit.
|
Evaluated 36 months after implant loading.
|
Crown-to-implant Ratio
Временное ограничение: 12 months after implant loading
|
Crown height measured radiographically from the implant-abutment interface to the most coronal point on the prosthesis.
The crown-to-implant ratio calculated from radiographs
|
12 months after implant loading
