"What is osteointegration?
ONCE AN IMPLANT IS PLACED IN THE JAW BONE, HOW IS IT HELD STRONGLY TO THAT AREA? I.E. WHAT MAKES AN IMPLANT BE HELD IN THE JAW BONE?
To answer this question, let's first get to know implants a little bit. Implants are made of titanium. Titanium is tissue-friendly and compatible with the bone tissue it is in contact with. The shape of the implant resembles a screw. The implant enters the jawbone by rotating like a screw, and retention is initially provided mechanically. An implant resembles a screw and Its outer surface is roughened. Thus, when the implant is placed in the bone, the contact area with the bone increases. After placing the implant in the jawbone, the bone around the implant is activated and bone producing cells begin to produce new bone. Thus, the bone around the implant is tightly wrapped and compressed. Let's go back to the beginning. The formation that occurs when we first place the implant. While the mechanical retention will come to the point of disappearing within 3 months, the biological retention formed by the growth of the bone around the implant will reach a sufficient level. This is called osteointegration.
Oral and Dental Health During Pregnancy
During Pregnancy Some of the important problems are gingival enlargement and changes in saliva. With pregnancy, the amount of sodium in the saliva decreases and the pH of the saliva decreases, meaning that the saliva is now more acidic. Saliva with increased acid density increases the risk of gum infection. The amount of potassium and protein in saliva also increases with pregnancy. Some of the changes that occur in the mouth during pregnancy are gum infection, gingivitis, gum disease. Pregnancy alone does not cause gum disease, but it paves the way for the occurrence of gum disease. Sometimes it increases an already existing gum disease.
Gingivitis that occurs during pregnancy is called pregnancy gingivitis. This disease is characterized by redness, swelling and bleeding in the gums. It is seen in almost half of pregnant women. This gingivitis is sometimes slightly red and painless. Sometimes it is very swollen, bleeding and very painful. It is more common in the front area of the mouth. Research shows that there is a connection between gum diseases in pregnant women and low birth weight and premature birth. The period from the beginning of pregnancy to the 14th week is the period during which the baby's organs in the womb are formed. During this period, dental intervention should be avoided as much as possible. The middle period of pregnancy is between the 14th and 28th weeks. The organs of the baby in the womb are shaped. It is the time period during which some treatments on teeth can be performed.
"zirconium crowns and bridges"
Zirconium is a chemical element. , symbol is Zr. It comes from the Arabic word zargon, meaning "color similar to gold".
It is a metal element in the 4-B group of the element table with the chemical symbol "Zr". Its melting point is 1855 degrees. It is a grayish white metal. It is extremely resistant to heat and corrosion. Its fracture resistance is 7-10 MPa. Its bending strength is 1570 MPa. Zirconium's high resistance to heat makes it a material with high dimensional stability.
Zirconium has a high degree of mechanical durability. It is a material with very successful aesthetics and advanced biocompatibility. It is the hardest ceramic known in the dentistry industry. It is used in blocks of various sizes in the dentistry industry.
Monolithic zirconiums are partially stabilized with yttrium (0.01%). This increased the mechanical resistance of the metal. Zirconium has become more preferred with its successful aesthetic properties. In addition, in the presence of insufficient interdental distance, the rate of making monolithic zirconium restorations on implants also increases. Monolithic zirconiums have a very successful natural appearance thanks to their non-porous structure and high transparency properties. Natural tooth color can be obtained by painting monolithic zirconium with special staining solutions. Considering these features, it is considered to be a material that can be used very easily for each tooth within the smile line without any aesthetic concerns. In addition, their wear resistance is close to natural teeth.
The high resistance of monolithic zirconia to fracture provides the advantage of use in cases where interocclusal distance is insufficient. It can show sufficient resistance and durability even with an occlusal thickness of 0.5 mm. Their features enable them to be used in posterior restorations.
