Basically, the skull is symmetrical structure; regularly abnormalities on one side of the skull model full fill with mirror image portion. By contrasting ordinary side of the skull with the deformity, an accurate portion for the malformation can be planned. In the zone of deformity, the mirror image can be exported to computer aided modelling software, which can precisely model an appropriate implant . This …show more content…
In an ordinary state, the volume of the cranial cavity, which is approximately 1700 ml, is occupied with three components: brain tissue (80%), cerebrospinal fluid (10%) and blood (10%). It varies with age, body position. An adult human being, when lying down, has a neutral value of intracranial pressure between 7-15 mm Hg [3,9,11] (pressure value expressed by a height of mercury column) which corresponds to 0.934-2.0 kPa.
Cranioplasty depends on autograft, allograft, xenograft, or uses synthetic material, not only to protect intracranial structures but also serves an aesthetic purpose. To best fit the hole on the skull and recover pre-operative head shape. Patients will feel more comfortable if post-operative shape resembles the original appearance.
The objective of this study was comparing both materials as cranioplasty implants in a simplified model. We wanted to investigate the structural changes that occur in the implants and the load-bearing material in a cranioplasty
