Implant Materials – Which One is Best For You?
Stainless steel, titanium, ceramic zirconia, and Surgical mesh are all popular implant materials. But what exactly are the differences between these materials? Which one is best for you? Read on to discover more! And then, choose the right implant for you! Here are some of the pros and cons of each material. Then, get in touch with your dentist to find out which implant is best for you! Let’s get started! Surgical mesh – It’s a great option for implants, but is it compatible with bone?
Stainless steel
A variety of corrosion mechanisms, including SCC, affect the durability of stainless steel implant materials. High nickel content minimizes the tendency of implants to form delta ferrite. 서초역치과 A high nickel content also provides better austenite stability. Higher chromium content is beneficial to corrosion resistance, but has a negative effect on austenite stability. Stainless steel implant materials have nominal nickel contents greater than commercial grades, a property essential for implant quality.
Stainless steel implant materials are classified according to their microstructure and composition. Some stainless steels are highly magnetic due to the austenitic microstructure. In addition, some austenitic stainless steels become magnetic when cold-worked. Implant quality stainless steels contain at least 10% chromium. This means that the implant cannot be heated or moved while it is implanted. However, a non-magnetic implant material is ideal for this purpose.
Titanium
The properties of titanium as an implant material are well understood. Although commercially pure titanium is the preferred material for dental implants, unalloyed titanium exhibits low strength and stiffness, which limits its use in this field. Further, new developments in implant design require implants with improved strength and low elastic modulus. These new materials should also exhibit a uniform distribution of deformation, which would influence the amount of stress induced by bone-to-implant attachments.
The biocompatibility of titanium is further enhanced by its low electrical conductivity. This property contributes to the electrochemical oxidation of titanium, which forms a thin passive oxide layer that is resistant to corrosion. Titanium oxide has an isoelectric point of five to six, making it ideal for use in biomedical implants. As a result, there are several titanium alloys on the market today that have superior biocompatibility.
Ceramic zirconia about Implant
The benefits of ceramic zirconia as an implant material are many. This biocompatible material has excellent osseointegration properties, and its surface topography is very similar to that of titanium. The surface of the ceramic is also very smooth, allowing epithelial cells to attach and grow more effectively. This smoothness is advantageous for oral keratinocytes, a type of highly specialized epithelial cell.
Although ceramic zirconia implants are not yet fully biocompatible, they have a high degree of biocompatibility and strength. They also have improved long-term success rates. Compared to titanium implants, ceramic zirconia implants do not form microgaps, which can cause a failure of the implant over time. This type of material is also better at osseointegration than titanium implants.
Alumina implants were briefly used in the past but showed poor survival rates. To address these issues, biomedical grade zirconia was developed. This material features a phase-transformation inside, which increases the crack-propagation resistance. Furthermore, the metastability of zirconia also increases its ability to age in water. In this way, ceramic zirconia implants are more durable than their alumina counterparts.
Surgical mesh
Mesh is a non-absorbable material, made of monofilament polypropylene yarns. Mesh pores are usually irregular quadrangles, but can also be triangular. Pores are formed by either a single thread running parallel to the material or two perpendicular to it. The size and orientation of the fibres also influence the interactions between the implant and the surrounding native tissue.
Typically, surgeons implant mesh to achieve maximum overlap over the defect, with little regard to its mechanical properties. The composite mesh is composed of a unique combination of polymer material properties and textile design, which influence the overall performance of the mesh after implantation. While weight is an important parameter, mesh also exhibits a variety of other properties that may influence the inflammatory response. For example, synthetic meshes with large pore structures exhibit better mechanical properties, and surgeons use them for a variety of applications.
Surgical meshes are often made from synthetic materials, which are commonly used for many surgical interventions, including hernia repair. They are composed of polypropylene, expanded polytetrafluoroethylene, and polyvinylidene fluoride. While these materials are considered biocompatible, potential complications associated with meshes include chronic pain and chronic infections. Despite the popularity of mesh implants, their use in hernia repair is still controversial.
