Dental implants have revolutionized dentistry, and provided the foundation needed to add fixed or removable teeth that match your own. With traces dating more than 2000 years ago, this procedure is still being used and is still evolving. Today’s trends revolve around several technologies, such as:
1. Finite element analysis
Since implants are prone to failures, proper analysis is a must. This three dimensional computer model, or FEA as it’s usually called, is now used to study the bones around the implants, predicting their stress distribution and heightening the success rate of the procedure.
2. Design and manufacturing with the help of computers
The creation process of dental implants keeps changing at a rather rapid pace. The implementation of techniques such as CAD/CAM has increased the accuracy and decreased the time needed for manufacturing implant parts.
3. Micro Casting
Using micro structured molds and metals, this method allows the creating of small structures and tiny details impossible to achieve through other means. Micro Casting is also quite cheap and can be used to create multiple identical items.
4. Electron microscopy
Due to the thin oxide layer, the more complex the geometry of the implant is, the rougher its surface gets and the more difficult the task of creating it becomes. However, with the help of electron microscopy techniques, one can measure accurately the lattice parameters, as well as the microstructure and the surface layer’s measurements (making the process much easier).
5. Implants based on nanotechnology
Techniques to create implants based on nanotechnology are currently being researched and for good reason. Modifying the surface of the implant on a nano scale increases the growth factors, which speed up the healing process of the bone, the cell adhesion and the protein absorption, as well as the calcium phosphate coatings.
Quite a few methods, like surface laser pitting and lithography, have been used to obtain nano-roughness in implants. However, with only a few studies confirming their usefulness, we will need a few more years before implants based on nanotechnology become available to the general public.
6. The functional gradation of materials
Functionally graded materials’ (FGM) main feature is their change in structure and composition over volume, causing modifications to occur in the material’s properties (specifically thickness). Thanks to this design, the mechanical behavior of the implant is optimized, the bone integration is improved as well as the biocompatibility.
After the first modern dental implant appeared around 40 years ago, their development and the creation of the ideal one has been a major concern for all those involved in the field. In recent years, implants have been improving constantly, giving patients the benefits of efficiency, low prices and convenience.
