Extraction Sockets

Limitations, open questions
> Using this method, an optimal soft tissue structure can be created during the 6-week time
frame between extraction and implantation. However, this time duration is not sufficient for a
bone regeneration to occur. Thus, in this indication, Geistlich Bio-Oss® Collagen is not used to
promote bone regeneration in the alveolus, but rather as a space maintainer to support the
buccal and crestal soft tissue contours as well as for stabilizing the blood coagulum.
> It is not yet clear whether, or to what extent, the Geistlich Bio-Oss® Collagen can also reduce
or prevent the resorption of the buccal bone lamellae.
> Currently, this method is still classified as experimental. The aim of future development is to
achieve comparably good clinical results without soft tissue grafting; this would simplify the
surgical procedure and be less demanding time-wise.

Remark: Method can be used with a smaller sized bone defect. However, the
method is not suitable for larger bone defects that require a two-stage procedure
(first bone augmentation and then implantation).
primary wound closure possible without problems

Soft tissue situation

primary wound closure poses problems from the esthetic aspect: Mobilization of a
buccal flap would negatively influence the mucogingival border.
yes, immediately

Bone augmentation indicated

yes, at the time of implantation
Remark: A bone augmentation is usually necessary to optimize the hard and soft
tissue contours.
no
yes, after about 6 weeks

Implantation planned

no
