Types of dental implants
Dental implants make it possible to fill the gaps in the patient's teeth. Their insertion allows for the reconstruction of single tooth crowns as well as prosthetic bridges or whole prostheses. They are stable, durable and durable, and most importantly - the patient is free to smile and eat even very hard foods without fear of falling out of the prosthesis. What types of dental implants are used in dental surgeries?
Established use time of implants
Taking into account how long dental implants will be used, we have two types of implants:
• temporary implants - mainly used in orthodontics, which can correct the bite,
• permanent implants - as attachments for removable dentures, prosthetic bridges or single crowns.
Place of placement of the implant
Another criterion for distinguishing different types of implants is the place, and the depth of their placement in the jaw or jaw of the patient. They can be divided into:
• Intraocular implants - fixed in the jaw or mandibular bone, where the implant is implanted in two stages - first, the implant is placed in the desired position, the dentist stitches the surrounding gums, and after 3 to 6 months and after integration of the implant with the bone, it is selected. At the top of it is assumed prosthetic casing - crown or connector for the bridge or prosthesis.
• Subcutaneous implants - fixed much more pliable, superficial than intraocular implants. They are located directly beneath the gums, so they only come into contact with the outer part of the bone. The implantation process involves only one stage where the implant tip remains outside. After healing the wounds are attached to the crown implant. This type of implant is used in patients with low density bones, which excludes the insertion of jawbone implant in their jaw or jaw.
Shape and size of dental implant
There are several types of dental implants that can be distinguished by their size and shape. Implants can have the shape of spirals, cylinders or bolts, but more and more often occur and their variations, varied in terms of their geometric shapes.
Typical dental implants are 3.5 to 4.2 mm in diameter, but smaller and larger types of implants - measuring up to 6 mm in diameter and about 2-3.5 mm in diameter. Depending on how much space is available for possible implant placement, the appropriate types are used.
Material for implants
The criteria for splitting dental implants can be the materials from which they were made. At present, dental implants are the most commonly used titanium, biocompatible implants that do not usually induce allergies and other types of allergic reactions in patients. Their surface is usually covered by different biomaterials or plasma of titanium oxide. Titanium is a material well tolerated by the human body, so titanium implants quickly integrate with the surrounding bones, making them ideal for supporting the crown, bridge or prosthesis.
In dentistry, zirconium implants are used, that is, ceramic implants made of zirconium oxide, which has been used for years in hip prostheses. They are made of zirconium oxide, which, like titanium, exhibits very good integration into the human body and is resistant to abrasion.
