Characteristics: Lamina barriers are made of cortical bone of heterologous origin produced with an exclusive Tecnoss® process that avoids the ceramization of hydroxyapatite crystals, thus allowing gradual resorption. After a process of superficial decalcification, Lamina soft acquires an elastic consistency, nevertheless maintaining the typical compactness of the bone tissue from which it originates; the margins are soft in order not to cause micro-traumas to the surrounding tissues. Curved soft Lamina has a semi-rigid consistency and should be grafted without hydration, provided that it is previously shaped to fit the defect morphology. Rigid Lamina undergoes a process of superficial semi-decalcification (50% vs Lamina soft) therefore increasing its consistency, typical of the cortical bone tissue^(1-2).
Clinical indications: Lamina soft becomes flexible after hydration and can be shaped⁽³⁾ and adapted to the defect morphology creating, once fixated with osteosynthesis screws, a semi-rigid covering to the underlying graft^(4-6). This property is particularly useful when it is necessary to maintain the graft volume in aesthetic areas, as well as in horizontal augmentation^(6-8) of two wall defects and in lateral access sinus lift procedures^(5,9,10). Lamina can also be used in regenerations with risks of exposure. Curved soft Lamina has a ~1.0 mm thickness and must be directly grafted without hydration⁽¹¹⁾: it can be particularly effective in association with GTO® for regeneration of ridges with compromised buccal plate. Rigid Lamina (ref. LS35LS) has been documented for orbital floor and wall reconstruction⁽¹²⁾.
The new 0.7 mm thickness Rigid Lamina (ref. LS15LS) represents a viable alternative to autogenous cortical bone plates in the reconstruction of three-dimensional crestal defects with the shell technique.
