Nine localized buccal ridge deformities were treated combining the use
of barrier membranes and resorbable space-making material. After elev
ating flaps, the bone defects were completely filled with calcium carb
onate and a fibrin-fibronectin sealing system (FFSS). Membranes (Gore-
Tex augmentation material) were then shaped and positioned to cover th
e calcium carbonate overlapping the surrounding bone. The flaps were s
utured, taking care to avoid any compression on the treated area. The
membranes were removed 4 to 5 months postoperatively: in all cases the
membranes were tightly adapted to the regenerated tissues and force w
as required to separate them from the underlying tissues. The defects
were filled with hard, bone-like tissue. The histology from one case,
taken 1 year postoperatively, confirmed the regeneration of bone and r
evealed the presence of a few residual particles of calcium carbonate
in the sample. The clinical appearance of the treated areas was satisf
actory for colour, texture and form. The horizontal deficiencies were
almost completely resolved in all cases, while the vertical component
showed incomplete filling in some cases.
