A custom orthotic in Oshawa is a shoe insert that changes how the foot reacts during walking. Most of these devices have a rigid base, whereas some are made of soft materials and will collapse or give way when the foot is put in a neutral position. This force causes discomfort when you first wear them, but this pain will subside over time as your foot gets used to the new position. When considering orthotics, you must know which materials are best for your needs. Let’s know about these materials.
Cross-linked polyethylenes are among the most common orthotics materials. These foams come in a variety of weights and thicknesses. They are excellent for pressure relief and total-contact applications. However, they have limitations, and patients should be aware of them before purchasing a polyethylene orthotic.
EVAs are firm but not uncomfortably hard, a characteristic similar to the shock-absorbing support of a running shoe. They provide shock absorption while being far more comfortable than rigid plastic orthotics.
Poron is one of the best materials for orthopedic devices because it offers a wide range of benefits, including flexibility, resilience, and shock absorption. In addition, it is breathable and offers load-bearing capability. This material also comes in various densities and colors, making it a popular orthotic choice.
Traditionally, soft orthotics are made of polyethylene or polyurethane foam. However, various materials can also be used, including plastazote (polyethylene foam) and other types of foam. A polyurethane mold has the advantage of slowly cooling the hot plastic. The downside of this material is that stockinettes can stick to it. To alleviate this issue, some practitioners use silicone mold release. Others prefer non-aerosol silicones, such as a water-based product.
Subortholen, or high-molecular-weight polyethylene, is an excellent material for orthotic cuffs and other lower extremity braces. This polymer is strong, rigid, and flexible. It is also resistant to cracking. It has excellent heat and cold-molding properties and is suitable for many orthopedic applications.
Latex foam is made from cellular rubber and has been used in orthopedics for many years. It is washable, odorless, and can be cemented into other materials. Other foams used in orthotics include Dynafoam(r), and ortho felt, a combination of wool and cotton.
