Background
Minimal or no crestal bone resorption is considered to be an indicator of the long-term reported success of implant restorations. Mean crestal bone loss ranging from 0.12-0.20mm has been reported 1 year after the insertion of single-tooth implant restoration. And after the first year, an additional 0.01 to 0.11mm of annual crestal bone loss.
Aim/Hypothesis
Aim of the report is to examine the change of alveolar bone lever of locking-taper implants .
Material and Methods
125 locking-taper implants in the present study were observed from March 2008 to March 2016. Case Presentation A 74-years-old patient who missed 35/36/37. He received treatment in a hospital in the U.S.A in August 2006. Two implants of BICON 4.5*8mm, 6*5.7mm were implanted into the position of 35/36. There was “angled alveolar bone resorption” at cervix of implant of 36 in January 2007. The situation doesn’t change until February 2008 when we did the second-stage operation. X-ray after 3 months of second-stage operation showed that alveolar bone developed a bit at the cervix of implant of 36. We finished the PFM in March 2008. We found the alveolar bone increased apparently at the cervix of implant of 36 after 1y , 2y, 4y,6y and 8y.
Results
125 implants in the present study (13.1%) showed crestal bone gain from March 2008 to March 2016. And the crestal bone mineralization were increased to the local strains engender by the natual opposing teeth during functional occlusal loading.
Conclusions and clinical implications
Peri-implant bone gain by locking-taper dental implant designs. The phenomenon of crestal bone gain around dental implants is supported by several longitudinal clinical studies on dental implants and has been commonly observed around locking-taper implants in our clinical experience.
