Different materials and properties of implants
Before delving into the differences between fourth grade titanium and fifth grade titanium in implants, let's first understand the material properties of each type of implant.
Biological properties of implants
·Biocompatibility: Whether the body will experience excessive rejection reactions to implants, ensuring the stability of osseointegration.
·Biosafety: Whether the materials of the implant are non-toxic and harmless, and whether the quality of the implant itself meets the standards.
·Biological functionality: After implantation, whether the implant matches the elastic modulus of the jawbone and supports chewing function.
Physical properties of implants
·Is it easy for the implant to experience fatigue fracture under the influence of various forces in the oral cavity after implantation.
·Whether the mechanical indicators such as tensile strength, yield strength, hardness, and elastic modulus of the implant meet the standards.
Chemical properties of implants
·Chemical stability: The presence or absence of an oxide layer on the surface of the implant isolates the impact of the oral cavity on the implant, ensuring its lifespan.
·Corrosion resistance: If there is an oxide layer on the implant, can the oxide layer effectively resist external corrosion.
What are the advantages of fourth grade pure titanium implants
In previous articles, we mentioned that "the higher the grade of titanium material, the higher its hardness and affinity." Next, we will elaborate on why we came to this conclusion.
Chemical components
Composed of titanium (Ti) with a purity of over 99% and containing a small amount of trace elements, fourth grade pure titanium has a higher titanium content.
Strength and hardness
Compared to grade five titanium alloy for implants, grade four pure titanium for implants may have a certain difference in hardness.
Resistance to corrosion
Fourth grade pure titanium implants have excellent corrosion resistance and can effectively resist the erosion of oral substances.
Biocompatibility
Compared to implant grade pure titanium and titanium alloys, implant grade four titanium has a greater advantage in biocompatibility.
Advantages of Grade 5 Titanium Alloy for Implants
After understanding the advantages of grade four pure titanium for implants, let's take a look at the advantages of grade five titanium alloy for implants.
Chemical components
Composed of an alloy containing 90% titanium (Ti), aluminum (Al), and vanadium (V), while also containing a small amount of trace elements.
Strength and hardness
Grade 5 titanium alloy for implants has excellent hardness and strength, and its hardness is close to stainless steel to a certain extent.
Resistance to corrosion
Implant grade five titanium alloy, like implant grade four titanium, can effectively resist the erosion of oxides and other chemicals.
Biocompatibility
Compared to grade four pure titanium for implants, grade five titanium alloy for implants has better biocompatibility.
reminder
Although different grades of pure titanium and different grades of titanium alloys have different advantages, in the process of selecting implants, it is still necessary to make a comprehensive judgment by implant experts based on the situation of missing teeth and the overall condition of the patient's body. The more expensive the implant, the better, and the cheaper the implant, the better.
It is generally recommended that if there are missing teeth and one does not know which implant to choose, it is advisable to promptly go to a reputable chain dental hospital for a dental examination. On the one hand, this can help to understand the situation of missing teeth, and on the other hand, after the examination, timely treatment measures can be taken to avoid the problem of missing teeth being left untreated for a long time, leading to the deterioration of "one missing tooth and three missing teeth".
