Why do implants break up? (First reason of the amount of force and design of the implant body)
 
The implant body and its components are likely to break, and this often occurs during prolonged periods of force.
The probability of a fracture is increased if more forces are applied to the implant. Angular forces and parafunctional movements and larynx can increase the risk of fractures. The risk of fracture will increase over time.
In the long run, 80% of the implant's failure is related to the fracture of the implant body. Implant body features that affect the risk of fracture include implant size, implant design, and biomaterial implant.


 

Many biodegradable materials are unable to tolerate the type and amount of parafunctional forces involved in tooth implants. Ceramics, for example, have excellent biocompatibility but are very vulnerable to violent forces. Bending forces are commonly applied to dental implants, making the use of ceramics in the body of the implant unsuitable.
Other examples are hydroxyapatites that are highly compatible with biological tissues, but their mechanical properties are not suitable for bearing implants.
In practice, many of these materials are used as coatings on stronger and stronger materials.
Implants should be able to withstand chewable forces, and the implant body should be very sturdy and titanium and its alloys have a successful history of application in dental and orthopedic treatments, and the bio-compatible compatibility of titanium excellent and its alloys is well documented.
In dentistry, there are 4 different categories (1 to 4) of titanium cp and 1 titanium alloys (Category 5). When the implant is placed in the bone, a titanium oxide layer forms, which makes the material well bone And tissues endure.
 
Titanium-Aluminum-Vanadium (Ti-6Al-4v) alloy has good mechanical and physical properties, corrosion resistance and excellent biocompatibility. The first advantage of titanium alloy (grade 5) is its titanium strength compared to other titanium grades.
In general, the mechanical properties of titanium alloys are better than titanium. Titanium alloy is 4 times stronger and tighter than pure titanium grade 1 and 2 times stronger than titanium grade 4.
Titanium and its alloys are very similar to bone areas in which metal is used as an artificial element and their hardness is 6 times more dense than cortical bone.
