Abstract
Osseus defects in the alveolar ridge can occur from trauma events, periodontal disease,
and infections. Reconstruction of osseus defects requires bone augmentation, which
is a crucial component of dental implant procedures, particularly in the aesthetic
zone where the availability of sufficient bone volume can be a challenge. The symphysis
block graft is a technique that has gained popularity in recent years for bone augmentation,
by harvesting a small section of bone from the mandible. The standard procedure usually
takes up to 3 to 6 months of a waiting period for implant placement after a bone graft
procedure; however, it is not impossible to simultaneously do the single stage surgery
of block graft and implant placement in the aesthetic zone. This article aims to evaluate
the outcome of autogenous block graft with simultaneous implant placement procedure
in the aesthetic zone in one single visit. A 21-year-old man presented with an edentulous
area in the upper front teeth and wanted to get tooth replacements of his missing
central and left incisors. The front teeth were avulsed and extracted after a road
traffic accident 3 months earlier, and the treatment given was a closed reduction
with arch bars for 2 months. The osseus defects in labio-palatal width was reconstructed
with a symphysis block graft as the donor and two implants were inserted into the
recipient site in a single stage surgery. A single stage surgery involving an autogenous
block graft with simultaneous implant placement is an effective technique and can
be considered safe with a high survival rate. However, further studies with long-term
evaluations need to be conducted to provide more evidence to support this protocol.
