Implants Overdentures

The removable implant prosthesis from iSmile Dental is a design that replaces lost teeth. It consists of artificial crowns and an acrylic base attached to artificial roots implanted in the jaw. The patient can remove such structures on his own without the help of a doctor.

iSmile Dental doctors recommend removable prosthetics on implants to those who do not want to replace missing teeth with traditional jaws on suction cups, and non-removable structures cannot be installed according to indications or limited financial capabilities.

Design Features

Systems in the mouth are fixed in several ways. They are attached to titanium roots with spherical abutments or locators.

Removable structures can be installed both on the upper and lower jaw. In the first case, prosthetics are carried out on at least four implants, regardless of the diameter and size of titanium roots. This is due to the soft and loose bone of the upper jaw. If there are fewer implants, it will be impossible to qualitatively fix an orthopedic prosthesis on them.

Removable prosthetics on implants have advantages. Products are firmly attached to the mouth, and food particles do not fall under them, as happens with removable structures on suction cups. The patient can easily remove the artificial teeth to brush and process them.

Push-button removable prostheses differ from traditional ones in the presence of additional fixing elements. Thanks to them, the design is securely held in one position - it does not fly off and does not shift. The advantage of this method of prosthetics is that it can be implemented both after classical and after mini-implantation.

A prosthesis for two implants can be installed only when the lower row is restored. At the same time, the diameter of titanium roots can be at least 4-5 mm; otherwise, the entire system's stability will suffer. If the teeth of the lower jaw are restored using mini-implants, then they will need as many as for the upper jaw - four.

On spherical retainers. The head of such products in shape resembles a ball. Prostheses with spherical fixation are inexpensive, but the design has one significant drawback. Gradually, the abutment leaders wear out and cease to hold the system reliably. After 2-3 years, you will have to see an orthopedist again. Due to the high wear and tear, the products are recommended as temporary.

On equator abutments (locators). Locators are shaped like a cone. Unlike globular heads, they wear out less. This type of fastener has another advantage - they can install orthopedic systems at a high inclination angle.

Beam fixation. Implants are interconnected by a titanium arc (beam) on which orthopedic systems are placed. After installation, the implant is combined with a beam, on which the prosthesis is fixed with a corresponding depression in the base. Due to this, the structure is not loosened, the fasteners are not erased, and the load is distributed more evenly. Beam prostheses are also removable but more durable.

Prostheses on spherical and locator fixators are installed on mini-implants or classical artificial roots. The prosthesis on the implants is placed 2-3 days after the implantation of artificial roots — no need to wait until they take root in the jaw.

Stages of the Procedure:

  1.   Manufacture of an orthopedic system. In the dental laboratory of iSmile Dental, special matrices are mounted in the prosthesis, which will snap at the top of the implant.
  2.   Implant placement. To implant thin titanium supports in the gums, the doctor makes a small puncture and installs implants in the jaw bone, where they stabilize for several days.
  3.   Fixation of the prosthesis. The doctor combines the abutments of artificial mini-roots with the matrices of the prosthesis.

After the procedure, the doctor will tell the patient how to care for artificial teeth.

Rules of Care

Preventive care - performed by a dentist:

  • professional cleaning of the prosthesis every year;
  • relocation of the structure;
  • repair of the entire system or its systems, for example, the matrix.

Regular care - daily actions of the patient to prolong the service of the product:

  • cleaning the surface of the prosthesis from food residues with an irrigator and brushes;
  • rinsing the structure with water;
  • storage of the system in antiseptic solutions one time per week.

Patients are also advised to abandon rough food, which provokes the appearance of chips and cracks in the system: crackers, nuts, and seeds.

The advantages of a removable type of prosthetics before a non-removable one are apparent - this is the low installation cost, especially if ball locks are used, and the possibility of self-correction of the position of the system.

Prosthetics on implants in the complete absence of teeth can be divided into three types: removable, non-removable, and conditionally removable. Removable prosthetics on implants are suitable for those patients who have already used a removable prosthesis but have not been able to get used to it.

When the patient does not have a single tooth, dentists recommend the installation of prostheses on implants or mini implants. The implant acts as a support for attaching a non-removable and even removable prosthesis.

Clasp prostheses on locks or telescopic crowns. These are reliable and durable conditionally removable designs that need not be removed or put on.

Dentures on suction cups are removable dentures. The design is fixed in the mouth employing a vacuum suction effect. Prostheses on the suction cups on the upper jaw are held very firmly, and on the lower – a little worse. Dentures with suction cups are increasingly used in dental prosthetics, i.e.

The surface of acrylic is perfectly smooth, and it does not injure the mucous membrane. Fewer microbes and food residues are retained on it. But the surface of nylon structures is rough, gradually darkens, and loses its luster. They are cheaper. The acrylic prosthesis will cost 1.5-2 times cheaper than nylon.

On average, dental implant service life is from 10 to 30 years. For some brands of implants, the manufacturer gives a lifetime warranty. This means that in case of detection of a defect or design inaccuracies on the implant itself, it guarantees to replace the implant – the analog of the root with a new one.

Conditionally removable prostheses on implants are permanent structures on screw fixation. The patient cannot remove them alone – only in the dentist’s office if it is necessary to repair or perform hygienic procedures.

The answer to the question “which removable dentures are the best for partial prosthetics” is unequivocal: clasp. They consist of a metal frame and a nylon or plastic base with artificial teeth.

The existing teeth hold partial removable dentures with the help of special hooks – clamps (for example, clamp fixation of clammer dentures) or special locks (telescopic fixation of dentures). Fixation of partial removable dentures is usually good, thanks to the supporting teeth.

An alternative to removable dental prosthetics is implantation. It is the implantation of artificial titanium roots into the jawbone and the installation of prostheses (crowns) on the — upper dentition: bridge prosthesis on the front teeth.
