The importance of metals and the use of organic compounds of the medium - metals in pharmaceuticals are being developed every day and the medications that are based on metals , plays an effective role in treating patients . In recent years, many metals have been unveiled in many diseases due to their therapeutic applications However , a limited number of them have entered the medical arena .
The medicinal uses of some of the most widely used metals are as follows :
Iron : Photodynamic therapies, lowering blood pressure, increasing phosphate concentration
Gold : Rheumatoid arthritis, asthma, malaria, cancer, bacterial infections
Silver : skin diseases, parasitic and microbial infections, diagnostic and imaging agents
Copper : diagnostic and imaging agents, radiotherapy, photodynamic therapies
Platinum : Malignant tumors, microbial and viral infections, photodynamic therapies
Magnesium : laxative, glandular hypertension, antacid
Cobalt : diagnostic and imaging agents, vitamin B12, photodynamic therapies
Chromium : Diabetes, diagnostic and imaging agents
Stainless steel or stainless steel is a wide range of special alloys that have a high resistance to corrosion, also called stainless steels. This type of steel is used in the medical , surgical , hospital , hospital , surgical beds , surgical beds , and sterile equipment . The resulting tools and equipment are used in medicine for ease of sterilization, corrosion resistance and sharpness.
Among stainless steels, stainless steel 304 is one of the most widely used grades in medicine and tool making due to its properties and price. The deep elasticity of the alloy is suitable for the fabrication of the sink and the medical vessels . The low-carbon version, called the L304, has welding capabilities to produce parts that require strong welding.
This type of steel does not suffer from brittleness or failure due to its usability at very low temperatures, and its hardening capability has led to its use in the production of high-strength parts. In addition, 316 stainless steel, due to the presence of molybdenum in its structure, has a better hardening and sharpening ability than 304 steel and is usually used to make needles, scissors and other cutting tools.
one of the uses of metal in the implant . Implants in the general sense are internal implants but are more common in dentistry. Implant surgery is a part of a dental implant that replaces a patient's natural tooth as a prosthetic tooth in the mouth. The use of root implants is thousands of years old . About 4,000 years ago bamboo was used in China and 2,000 years ago in Egypt, precious metals were used to replace teeth. However, the first dental implants were made of stainless steel in 1932, but about 70 years ago, in the early 1950s, scientists discovered bone growth around the metal of the rabbit during the study of rabbit thigh bone and used it in Oral, finally, the first dental implant was made in 1965 using a titanium alloy. Titanium alloy is the most common material used for intra-dental implants and is used to make fixtures, bridges, overdentures and prosthetic implant components.
The most important reason for using titanium alloy for the implant is good consistency with the body . Insufficiency, high corrosion resistance, thermodynamic conditions, its properties against pH and low ion generation are some of the physical properties of titanium that make it suitable for compatibility.
Artificial heart valves, joint implants such as hips, knees, shoulders and elbows, as well as implants and tooth pins are among the applications of titanium-based alloys in medicine. Recently, titanium has also been used to make medical instruments such as needles and scissors. The use of titanium in biomedical is also very common because it meets the requirements better than competitors such as stainless steel, CoCr alloys, niobium and tantalum with commercial purity. Properties of biomedical applications include corrosion resistance, biocompatibility, adhesion (internal bone growth), fatigue strength, and proper processability such as casting, bonding, and modulus of elasticity, which should be as close as possible to the bone modulus.

Although gold is now more of an ornamental concept, and its market for jewelry, coins, and… is becoming more and more popular, it is also used as a restorative material. Because pure gold is relatively soft, its use is limited to parts that are not subject to high loads or pressures. Hence, gold alloys are chemically inert, non-allergenic, and resistant. They are useful for dentistry due to their corrosion and stability . These alloys have mechanical properties that are superior to pure gold, and the addition of copper in the gold field improves the strength of the resulting alloy and its mechanical properties. In general, gold alloys are used for fillings, dental veneers, bridges that connect dentures to the natural, and orthodontic appliances.
Although only some metals in the field of health and medicine are capable , aluminum is one of the most toxic metals in this field . This metal, due to its high resistance and strength against corrosion, rust, low density, non-toxic, high machinability and ease of recycling, are among the metals that can be used in medical industries and equipment and hospital space. It is one of the top metals in the field of health and wellness. Another application of aluminum is its plating properties, which increases its resistance to abrasion and scratches.
Patients with dialysis and use medical equipment and equipment in this regard . People who go to the hospital for x-rays, people who have slept in hospital beds many times, people who spend an hour on dental chairs in dental chairs, and people with wheelchairs and walkers for They have benefited from displacement, aluminum has somehow played a role in their lives, even if they are not aware of it. The main applications of this metal are in the field of making different types of hospital beds, making different types of dental chair units, making different types of wheelchairs, walkers and stretchers, equipment for dialysis of kidney patients and X-ray imaging.
