- receiving bed - donor site - fibrin glue
The author focuses his attention on the careful finishing of the receiving bed of a free implant to achieve the most favourable morphologic adaptation of the implant on a specific suture, so as to stabilize it in the current unfavourable anatomic situation, and then on protection of the vast donor site with properly prepared fibrin glue.
|Fig. 1 Insufficient adhering gum|
|Fig. 2 Receiving bed is prepared by thinning the periosteum by chamfering the margins of the bed and scarifying the gum adhering mesio-coronal-distally to the bed itself.|
|Fig. 4 Graft is test-placed on receiving bed|
|Fig. 3 Graft is taken.|
|Fig. 6 The fibrin glue is prepared: it is reconstituted with one solution of freeze-dried Tissucol containing fibrinogen and Factor XIII and a solution of Aprotininia and another of freeze-dried bovine thrombin with a solution of calcium chloride at a concentration of 500 I.U./ml. The two solutions thus prepared are sucked into two separate syringes. These are then inserted into a two-way syringe, thus allowing the two solutions to blend and form fibrin glue on coming out of the needle.|
|Fig. 5 It is sutured with single stitches and an apical subperiosteal cross stitch penetrating through the compact tissues of the gum distally adhering to 3.4 in the vestibular-lingual direction and emerging mesially at 3.3 in the lingual vestibular direction and is then tied to the graft.|
|Fig. 7 A thin layer of Tissucol is deposited on the donor site.||Fig. 8 After five months the cure is at its best.|
|Fig. 9 Appearance of graft following removal of the second pack on day fifteen.|
|Fig. l0 After five months the blending of the graft is quite good (Anglo-Saxon authors thus define all factors that influence the morphological adaptation of the graft).|
