The Benefits of Plastination
The Alternative to Artificial Models
The use of authentic human specimens presents an up-close look at human anatomy in a way that cannot be shown with three-dimensional models. When the physiochemical treatment is performed correctly, the microscopic cell structures maintain their original shape. Plastinates are accurate representations of preserved bodies illustrating all functional structures perfectly and are visually appealing.
The Alternative to Formalin Specimens and Wet Specimen Dissection
Traditionally, medical students familiarize themselves with the human body through a process of removal. First, they remove the skin from the cadaver. They then detach the muscles from the limbs and, finally, conclude by removing the chest and abdominal walls. After removing the organs, the remainder of the body is, to use the rather telling term, “dissected down” to the bones and ligaments.
Health Aspects
In many countries, laws limit how much time someone should be exposed to formaldehyde fumes due to their carcinogenic effects. Many universities have to make substantial investments to bring their laboratories up to the legal standards. In addition to being non-toxic, plastinates can also help limit or completely exclude formaldehyde fume exposure by reducing the time spent dissecting and then studying wet specimens.
Effective Curriculum
Plastinated specimens allow for precise preparation, planning, and compliance to a specific curriculum. Traditional wet dissection can lead to unanticipated surprises such as collapsed organs or unwanted appearances of diseases. Because plastinates guarantee visibly clear anatomical structures or specific abnormalities, teaching with them is very effective and results oriented.
Practical Aspects
Many universities maintain their own body donation programs. Such programs are time consuming and require considerable organization, care and appropriate administration. Due to rising costs, smaller universities may not be able to maintain wet specimen dissection programs or may need to severely limit them. Additionally, due to religious and cultural restrictions, institutions in some countries may not have any access to body donors. Aside from problems with availability, wet specimens are difficult to transport and can only be used and stored in specific, approved locations. Plastinates, however, can be used wherever needed and can easily be transferred between teaching locations.
Economic Aspects
Growing enrollment numbers, larger class sizes, and budget cuts have led to enormous economic pressure on many institutions. The use of plastinated specimens does not only improve the quality of education, it also has clear economic benefits. While many wet dissection programs require costly and regular maintenance, plastinates need almost nothing in terms of maintenance. Simple dusting and color touch-ups (occasionally needed after 5 years) are the extent of maintenance needed for plastinates. Due to their durability, plastinates can be reused year after year, and therefore typically recoup their costs after only a few semesters.
Quality
Quality and References
Our plastinates benefit from 40 years of continuous development and improvement of the Plastination technique. Anatomists, professionals and experts recognize and appreciate our detailed, high quality dissections. The precise and thorough practice of each step in the process, particularly, complete water and fat removal is important to ensure the durability of each specimen. Shrinking and color changes are avoided by precise methods used in our laboratory. At von Hagens Plastination we pay special attention to our processes, which have resulted in perfecting each of the steps in Plastination, to ensure the highest quality specimens.
