			Clinical method
						Fig. 9 Positioning of the fibrin glue with a two-way syringe and the aid of a celluloid mould placed in the bone defect to ensure proper fitting of the glue to the distal surface of the root.
	Fig. 8 The poster presented at the SidP congress in Catania in 1987 which summarizes the method used in isolating the periodontal space.
						Fig. 11 The amniotic membrane during positioning.
		Fig. 10 The Interpore 200 implant.
Results
								Fig. 14 X-ray after 8 months: the bone is forming and the periodontal space is maturing.
	Fig. 12 X-ray of the bone defect before the operation.
					Fig. 13 X-ray of the bone implant clearly not in contact with the distal root surface.
	Experimentation on the dog
					Fig. 16 The bone defect is shown following artificial preparation and stabilization. The defect is 10 mm deep.
								Fig. 17 Careful radicular curettage follows (compare with Fig. 31 concerning histological examination).
			Fig. 15 At the beginning of experimentation on the dog, a flap having mucoperiosteal thickness at the level of the second upper right premolar is sculpted.
		Fig. 18 The fibrin glue, prepared at a concentration of 500 I.U./1 ml with a Duplojet two-way syringe and a celluloid mould placed in the defect to facilitate adaptation of the glue to the root surface.				Fig. 19 The amniotic membrane has been placed on the fibrin glue over the entire apico-coronal surface of the root.
