Removable prostethics

When the situation in the oral cavity is such that fixed prostheses are not feasible, dental medicine offers the possibility of removable or combined works.
Combined works involve the solutions that are only partially fixed within the mouth, while the remaining part of the prosthesis remains removable and must be regularly taken out for oral hygiene.

Removable prostheses can be total or partial. While total prostheses are exclusively made of acrylic, partial prostheses can be made of two types of material: acrylic or wiron (with metal base).

The solution proposed depends primarily on the condition of the patient’s oral cavity.

When choosing the type of work to be performed you can rely safely on the suggestions and solutions proposed by our experienced staff.

Cover prosthesis on implants

An ideal solution for a prosthetic rehabilitation of a toothless oral cavity. In comparison with a total fixed prosthetic replacement, the cover prosthesis requires fewer placed implants, which, along with a greater possibility of the implementation of the planned therapy (based on the quantity and quality of the remaining bone structure), and a less invasive intervention, greatly decreases the financial aspect of the therapy as well. The main retention element is the bar. Fixed on four previously placed implants, it makes a primary (inverse matrix), while a secondary (matrix) is placed inside the prosthesis. Along with great retention and a completely reduced prosthesis base, the cover prosthesis on implants offers an ideal prosthetic replacement, comfortable for the patient.

Wiron prosthesis (with metal base)

Classic wiron prosthesis is a mobile acrylic prosthesis with a metal base. It is used as a permanent solution of partial toothlessness if no other option is available. The retention is achieved in the form of cast posts that enclose with precision the supporting tooth. This transfers the biting pressure to the tooth and the bone, while the option to reduce the base of the prosthesis plays a great role in maintaining the patient’s oral comfort.

Combined prosthetics replacements

If the arrangement of the remaining teeth is favorable, there is a possibility of modifying the wiron prosthesis by replacing posts as retention elements with joint attachments. The remaining teeth in the oral cavity are whetted and covered with a metal ceramic bridge that has embedded attachments on the edges in order to achieve retention on the principle of the matrix. This is referred to as combined work, that is, a combination of fixed and removable prosthetic replacements.

Telescopic dentures

They represent modified wiron prostheses that are an ideal solution for a prosthetic rehabilitation of subtotal toothlessness with unfavorable teeth position. The remaining teeth are whetted and covered by a total primary metal crown (gold), while a secondary crown is placed inside the wiron prosthesis. An excellent retention is achieved, with the friction between the two metals, based on the matrix principle.

Acrylic prosthesis

A total acrylic prosthesis is a removable prosthetic replacement made from acrylic. It is the only solution for a prosthetic rehabilitation of a toothless oral cavity if implants are not an option. Retention elements are soft gingival and firm bone structures, as well as negative pressure and resilience of mucous membrane.

A partial acrylic prosthesis is most commonly used as a temporary solution for the lack of individual teeth. It differs from a total prosthesis in the retention obtained by cast posts around existing teeth.

Fixed prosthetics

Zirconium-oxide ceramics

Ideal aesthetic results in treating front teeth are achieved with the application of press-ceramics or zircon oxide.
Zirconium is a relatively new material in dental medicine and certainly the biggest discovery concerning the metal ceramic crowns. Zirconium, as a material, is biocompatible, it does not react to surrounding tissues, it is a weak heat and electricity conductor that minimizes teeth oversensitivity and it is an unfavorable base for plaque build-up, which greatly improves oral hygiene care and slows down gingival recession. Along with the mentioned advantages, zirconium is a material strong enough to bear chewing forces of the lateral region without getting fractured, and does not have a metal base. The aesthetic characteristics are exceptional and give technicians the possibility to model a crown that is difficult to distinguish from a natural tooth.

Metal-free ceramics (press)

It is used exclusively in the frontal region in order to achieve high tooth aesthetics in the shape of a crown or with minimally invasive facings technique (veneers). Since there is no base that gives it firmness and strength it is not suitable for lateral regions because of the strong chewing forces.

Metal ceramics

With the development of dental medicine and dental materials, metal ceramic crowns have replaced total metal crowns. The metal ceramic crown consists of a metal base (cobalt – chrome – molybdenum, nickel – titanium, gold) fused with ceramic in special laboratory conditions. This enables the crown to assume the shape of a tooth, with satisfactory aesthetic results. Due to the resistance of the metal base and the ceramic aesthetics, metal ceramic crowns and bridges are used in both lateral and frontal regions.

SLM technology

(abbreviation for selective laser melting)

This method is used for affixing layers of metal dust by a laser beam.

The scanned conditions of the oral cavity are digitally transmitted onto the screen. The dental technician then virtually models the construction. The tridimensional data thus obtained are subsequently turned in a bidimensional cut that the SLM device applies, a layer at a time, and in this way builds the construction.

BEGO was the first to present this kind of technology in Germany in 2001. It is the BEGO company itself that produces prosthetic constructions for our patients. German precision and quality guarantee our patients a safe and long-term product.
