IMPLANTOLOGY

GUIDED BONE REGENERATION AT

IMMEDIATE IMPLANT PLACEMENT

Meet Shah

THE SITUATION
A 45-year-old female patient reported to the dental office with pain, discomfort,
and swollen gums in the lower front tooth since the past few days. Tooth #31
showed a vertical fracture, resulting in chronic periodontal involvement.
Probing suggested missing labial cortex of #31. Tooth #41 was also affected. It
was decided to extract teeth #31 and #41 and replace them with a fixed, aesthetic
restoration. A 3D bone augmentation was also planned to be performed with
Geistlich Bio-Oss® Collagen and Geistlich Bio-Gide® membrane.

THE APPROACH
The aim of this clinical procedure was to regenerate the hard as well as the soft
tissue compartment to provide long-lasting, functionally stable and aesthetically
pleasing implant supported prosthesis. The implant was placed in the region
of tooth #41 and tooth #31 was planned as a cantilever to provide sufficient
cancellous bone around the implant. The defect was filled with Geistlich Bio- Fig 1: Pre-operative picture displaying the initial situation of the
