Prosthetics involves the introduction of a metal pin with a screw thread instead of the removed root. Priority – conical, repeating the anatomical shape of the incisors and molars, minimally injuring the gums. The intermediate part – the abutment – the rod of the supragingival part serves to connect and hold the crown. The latter are made to order in the dental laboratory from metal or zirconium, or factory ones are used. The stronger the material, the higher the cost of production.
In the case of a thinned bone with a small size of the alveolar bone (less than 5 mm), subperiosteal or subperiosteal ones are selected for placement of dental implants. They are made in the form of a figured metal structure with protruding supports. Attach under the gum to the lateral jaw, and not through the hole of the removed root. The protruding parts hold firmly removable and fixed prostheses, do not cause problems when chewing food, and retain a natural articulation.
These systems are most popular among clinic patients. The absence of damage to the integrity of the gums and bone tissue during installation promotes rapid healing after. Prosthetics is indispensable, if you need to strengthen the root, keep the functionality of the device. The procedure is carried out through a lost or partially preserved peak. The surgeon implants a screw into the root through the channel of the removed nerve. Crowns or a bridge attached to supports protruding above the gum.
A mushroom-shaped orthopedic system with an extended platform for prosthetics of the toothless upper jaw is used to fix the prosthesis with complete atrophy of the alveolar process. First:
- make a complete removable denture;
- carry out the installation of the implant at the base, distributing artificial teeth along the alveolar bone and palatine arch;
- prepare the recess in the structure.
The procedure for installing implants: with the help of point anesthesia they are sutured into the mucous membrane in the region of distal tubercles on both sides, on the frenum of the upper lip. After a month, the sutures are removed, the prosthesis is removed, partially removed in the palatine part, polished, fixed.
Structures 60 mm long, manufactured using Nobel Zygoma technology, are used in a number of cases:
- with dystrophic pathologies of the maxillary bone;
- complete or partial edema;
- atrophy of hard tissues caused by the absence of teeth when wearing dentures;
- mechanical damage.
A feature of the method is the fastening of the trans-buccal system. First, it is passed through the jaw, then attached to the zygomatic bone. Thanks to this method, you can avoid the procedure sinus-lift.
