- Abstract
- The healing potential of individual polymer implants for the reconstruction of extensive craniofacial defects after cancer resection is largely determined by the internal architecture of the implant. The architecture of an implant during polymer crystallization could affect the structure and shape of the implant at the micro and macro levels. In this study, the relationship between the internal architecture (triply periodic minimum surface structure (gyroid), cube, grid, and honeycomb) and shape changes of individual implants by 3D printing with a vinylidene fluoride-tetrafluoroethylene copolymer after crystallization is examined at a filling density of 70%. Using the method of differential scanning calorimetry, it is established that crystallization leads to the rearrangement of the crystalline structure of the implant into electrically active (ferroelectric) crystalline phases. Moreover, the type of internal architecture affects the change in the shape of the implant after crystallization. The results of the computed tomography show that structures with a triply periodic minimum surface (gyroid) provide the minimal deformation of the implant during crystallization, which makes such structures optimal for manufacturing implants for replacing bone defects in the zygomatic-orbital complex.
