Popis: | 102 The principle of nanosprous composite from the concept of guided tissue regeneration (GTR), by using membrane to block the upper soft tissue, prevent the soft tissue first ingrowth to the bony defect area to be rebuilt, enable migration and proliferation of slower growth bone cell, in order to achieve the purpose of bone regeneration. The healing process can be confirmed by histological studies – regeneration of functional periodontium occurs only as the connection of periodontium to root surface. When periodontium gradually healed, the use of membrane isolated from the faster growth gingival epithelial cells that provide a stable environment and physical space for the slower growth cells (cementum, periodontal ligament, and alveolar bone) to retain its original growth area, as well as tissue repair time required. Pore size, thickness, strength of regeneration membrane, as well as its physical-chemical quality of material (biocompatibility) will affect the final outcomes of guided tissue regeneration directly. Therefore, it become a very important issue to find out a method for controlling the pore size, structure and physical-chemical quality of regeneration membrane. This study will utilize the composite as a substrate, and then by the mechanical properties, physical and chemical properties test, in order to obtain the optimized composite membrane. It can be a favorable basis for future animal experiments and clinical trials. |
