Lamina

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.

Handling
Lamina 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.
