CharacteristicsLamina 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).HandlingLamina soft soft can be shaped with sterile scissors until the desired size is reached, then it must be hydrated for 5/10 minutes in sterile physiological solution. Once it acquires the desired plasticity, it must be adapted to the grafting site; it should always be immobilized either with titanium microscrews or sutured (fine model) directly to the surrounding tissues with a triangular section non-traumatic needle. Curved soft Lamina should not be hydrated in order to maintain its tenting effect but can also be shaped with sterile scissors, and must be fixated with osteosynthesis screws. In case of exposure, Lamina soft should only be removed if there is a clear suprainfection, because its consistency allows to achieve a complete second intention healing of the wound.Clinical informationLamina 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.
