Introduction:
The success of hard
tissue regeneration techniques in the pre-implantation phase is
correlated with the primary healing of the surgical wound. For this
reason, the essential moment in the implementation of this procedure is
the passivation of the flaps and their sufficient mobilization.
Aim:
The study aimed to obtain an increase in the soft tissue volume using
surgical expanders and then proceed with guided bone regeneration
techniques.
Case presentation:
Two patients presented for implant procedures with clinically and
radiologically confirmed diagnoses of bone tissue atrophy and fibrous
scars on soft tissues which were to be healed in the phase of
pre-implantation preparation. Osmed® expander, which was used in the
procedure, consists of a hydrogel, a copolymer of methyl methacrylate
and N-vinylpyrrolidone, and is contained in a cylindrical perforated
silicone sheath. The final soft tissue expansion after 4 weeks was
increased in volume by about 38%.
Conclusion:
The technique of increasing the volume of soft tissue with the use of an
expander enabled the increase of soft tissues in a separate surgical
procedure, freeing the surgeon from the relaxation of the flap during
the phase of implanting the artificial bone, and thus excluding possible
disturbing factors that interfere with the primary healing of the wound
during that surgical procedure.
