In the field of edentulous restoration, bracket-based removable partial dentures (commonly known as removable dentures) are the most commonly used method. They utilize natural teeth and the mucosa and bone covering the base for support, relying on the denture's retainers and base for retention. Artificial teeth restore the form and function of the teeth, while the base material restores the morphology of the alveolar ridge and soft tissue defects. Patients can remove and wear these brackets themselves, providing a convenient restorative option for edentulous patients.
Bracket Classification and Characteristics
Based on the material used, common types on the market include PEEK, pure titanium, and cobalt-chromium. Each material has its own advantages and disadvantages. PEEK and pure titanium have better intraoral compatibility, but are relatively expensive. Cobalt-chromium braces are more affordable, but can have a stronger foreign body sensation. With market development and innovations in raw material technology, titanium alloy braces are becoming increasingly mature and are gradually gaining popularity among consumers. Widespread Application of Titanium Alloys in Dentistry
Titanium alloys are widely used in the dental field. They can be used in the manufacture of various artificial joints, artificial bones, bone fixation devices, dentures, dental inlays, fixed bridges, and more. The titanium alloy mentioned in this article has a primary chemical composition of titanium (89%), which is nearly pure titanium. The remaining components and their contents are approximately: aluminum (Al): 5.5-6.5%; vanadium (V): 3.5-4.5%; oxygen (O): ≤0.13%; iron (Fe): ≤0.25%; nitrogen (N): ≤0.03%; carbon (C): ≤0.08%; hydrogen (H): ≤0.008% (parameters vary depending on the actual specimen).
Advantages of Titanium Alloys as Human Implants
Titanium alloys offer many significant advantages as human implants:
Lightweight: With a density of 4.5 g/cm³ (at 20°C), implantation reduces the body's load and provides greater comfort for the patient. Low elastic modulus: After implantation, it more closely resembles the body's natural bone, facilitating bone grafting and reducing the stress shielding effect of bone on the implant, thus ensuring bone health.
Non-magnetic: Unaffected by electromagnetic fields and thunderstorms, ensuring safety during use and eliminating the need for patients to worry about potential risks in special environments.
Non-toxic: The implant has no toxic side effects, providing reliable protection for patient health.
High corrosion resistance: As a bioinert metal material, it exhibits excellent corrosion resistance in an environment immersed in human blood, ensuring good compatibility with human blood and tissue, and extending the lifespan of the implant.
High strength and toughness: Implants are left in the human body for long periods of time and are subject to bending, twisting, squeezing, and muscle contraction. The high strength and toughness of titanium alloys meet these requirements and ensure implant stability.
