The aim of the present retrospective analysis was to assess peri-implant tissue conditions and document peri-implant tissue stability in C-Tech implants when placed simultaneously with a GBR (Guided Bone Regeneration) augmentation procedure.
A total of 47 implants, which were placed simultaneously with a GBR (Guided Bone Regeneration) procedure with a synthetic bone substitute material in 20 patients, were investigated clinically and radiologically at least 3 years after loading.
The follow-up investigation revealed a survival rate of 100% and only low median rates for probing depths (2.7 mm) and BOP (bleeding on probing) (30%). The mean PES (Pink Esthetic Score) was 10.1 from the maximum value of 14.
No osseous peri-implant defects were obvious, and the mean bone loss was 0.55 mm.
In conclusion, implants placed in combination with a GBR (Guided Bone Regeneration) procedure can achieve long-term stable functionally and esthetically satisfying results for replacing missing teeth in cases of atrophy of the alveolar crest.
