Fiber Retention Osseous Resective Surgery (Carnevale 2007): brief Description of the Technique
First step: flap design At the buccal sites, internally bevelled incision that can be intrasulcular or extrasulcular, depending on the probing depth and the apico-coronal dimension of the keratinized tissue. A split-thickness flap is then incised beyond the mucogingival junction. In case of thin soft tissue, a combined flap (split–full–split thickness) is suggested. At the mandibular lingual sites, a full-thickness flap is recommended. At palatal level, palatal thinned flap is the procedure of choice.
Aimetti Knife 1 Intended use: Spear point Periodontal Inter-proximal Knife for carefully removing the supracrestal soft tissue at inter-dental sites during gengivectomy procedures associated with osseous resective surgery. This blade was specifically introduced for its application in Fiber Retention Osseous Resective Surgery Technique. Clinical significance: thanks to its sharp cutting edges, it permits fine control during the selective dissection of the granulation tissue from the connective fibers attached to the most concave portion of the periodontal defect. Moreover, its anatomical shape allows for better access in narrow inter-dental spaces compared to commercially available inter-proximal knives (Orban 5/6, Buck 1/2, Goldman-Fox 8/11).
Third step: ORS Inter-proximal bone reshape by considering the coronal level of the fibre system as the bottom of the defect. This reference point, being more coronal than the real base of the bony defect, minimizes bony removal in order to level the adjacent buccal/lingual bone to the inter-proximal retained fibres. An inverse bony anatomy generally results following this inter-proximal reshape. In order to recreate a positive bony architecture, ostectomy/osteoplasty is performed in these areas using diamond-round burs and chisels. Inter-proximal bone is more coronal than that consequential to a traditional approach, the amount of buccal and lingual bony removal is also reduced. Second step: marginal soft tissue removal and fibre retention Soft tissue removal begins at the buccal and lingual sites, by using a blade number 15. At inter-dental sites, an inter-proximal knife (Aimetti 1/2) is used to sharp dissecting the granulation tissue from the connective fibers attached to the most concave part of the crater. The blade is positioned in the interdental soft tissue over the most coronal part of the buccal and lingual walls of the bony defect and permits precise severing buccolingually. All the soft tissue not attached to the root surface is carefully removed, leaving only fibres connected to the root cementum in the infrabony defect.
Aimetti Knife 2 Spear point Periodontal
KAIMETTI1 Aimetti Knife 1
Inter-proximal Knife similar to Aimetti 1, except blades are offset for easier handling in more posterior region (distal to first/second molars).
Fourth step: suture of the flaps Suturing of the apically positioned flap requires periosteal anchorage.
