Randomized, Open Investigation Evaluating the Efficacy of Nobel Biocare SFB and CFB Implants
|Partial Edentulism Complete Edentulism||Device: NobelActive Internal implant Device: NobelActive External implant Device: NobelReplace Tapered Groovy implant|
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Evaluation of NobelBiocare SFB and CFB Implants|
- The Primary Endpoint Was the Change in Marginal Bone Levels (in mm) From the Time of Implant Insertion to Follow-up Visits (3,6,12,24,36 and 60 Months). [ Time Frame: baseline, 3 months, 6 months, 12 months, 24 months, 36 months and 60 months ]
Marginal bone remodeling is calculated for each side of the implant (mesial and distal) separately, as the difference between bone levels at two time points. The average of mesial and distal remodeling is then calculated for each implant site (paired for each side between two different points). Negative numbers indicate bone loss. Implant insertion was defined as a baseline.
Missing data was not imputed and not included in evaluation.
- Implant Survival Rate From the Time of Implant Insertion to Follow-up Visits (3,6,12,24,36 and 60 Months). [ Time Frame: baseline, 3 months, 6 months, 12 months, 24 months, 36 months and 60 months ]An implant was reported to be a surviving implant when it remained in the jaw and was functionally loaded even if not all the individual success criteria were fulfilled (i) an implant that causes no allergic, toxic or gross infectious reactions either locally or systemically, ii) offered anchorage to a functional prosthesis, iii) showed no signs of fracture or bending, iv) showed no signs of peri-implant radiolucency on an intraoral radiograph using a paralleling technique strictly perpendicular to the implant-bone interface, and v) showed no mobility when individually tested by either tapping or rocking with a hand instrument).

The purpose of this study is to determine safety and efficacy parameters for the NobelActive Internal and External implants and to make comparisons with the NobelReplace Tapered Groovy implant placed in healed sites.
- survival rates,
- marginal bone resorption with marginal bone levels measurement,
- soft tissue health and maintenance via gingival index measurement, plaque index, papilla index .
