When the situation in the oral cavity is such that fixed prosthetic replacements are not feasible, dental medicine offers the possibility of mobile or combined prosthetic replacements. Mobile dentures can be total or partial. While total dentures are made exclusively of acrylate, partial dentures can be made of two types of material: acrylate or wirone (with a metal base). Which solution will be offered to the patient depends primarily on the situation found in the oral cavity.
The ideal solution for prosthetic rehabilitation of the edentulous jaw. Unlike a fully fixed prosthetic replacement, a cover prosthesis requires a smaller number of implants, which, along with a higher probability of implementing the planned therapy (looking at the quantity and quality of remaining bone) and a less invasive procedure, greatly reduces the financial aspect of therapy. The main retention element is the bar, which fixed to the four previously placed implants forms the primary (patric), while the secondary (matrix) is located inside the prosthesis. With excellent retention and a completely reduced denture base, the implant cover prosthesis is an ideal and patient-friendly prosthetic replacement.
The classic wiron prosthesis is a mobile acrylic prosthesis with a metal base. It is used as a permanent solution to partial edentulousness if other options are not possible. Retention is achieved in the form of cast brackets that precisely enclose the abutment tooth, thus favorably transmitting masticatory pressure to the tooth and bone, and the possibility of reducing the denture base plays a major role in the comfort of wearing the patient.
If the arrangement of the remaining teeth is favorable, there is a possibility of modifying the wiron denture in such a way that the brackets as retention elements are replaced by articular connections (attachment). In that case, the remaining teeth in the jaw are ground and covered with metal with a ceramic bridge, which has built-in articulated connections at its ends, which achieve retention on the principle of the patrix and the matrix. Then we talk about combined work or a combination of fixed and mobile prosthetic replacement.
* Combined prosthetic replacements include those that are only partially fixed in the mouth, while the rest of the prosthesis is mobile and needs to be removed for oral hygiene.
They represent a modified wironit denture which is an ideal solution for prosthetic rehabilitation of subtotal edentulousness (up to 3 remaining teeth in the jaw) with unfavorable tooth position. The remaining teeth are ground and covered with a primary complete metal crown (gold), while the secondary crown is located inside the wiron denture and excellent retention is achieved by friction of two metals on the principle of a patrix and a matrix.
A complete acrylic prosthesis is a mobile prosthetic replacement made of acrylate. The only solution for prosthetic rehabilitation is edentulous jaw if implants are not possible. Retention elements are soft gingival and hard bone structures as well as negative pressure and mucosal resilience.
Partial acrylic dentures are most commonly used as a temporary solution to the lack of individual teeth. The difference from a complete denture is in the retention that is achieved by the brackets around the existing teeth.
