Types of Removable Dentures

Contents:

Several classifications of removable dentures in a dental practice fully reflect their main features regarding the masticatory function restoration and aesthetic appearance of a smile. There are the following types of prostheses classified by size:

  1. Full dentures. This type of prosthesis can completely cover the upper or lower jaw. Removable full dentures are most commonly applied in case of complete edentulousness (absence of all teeth).
  2. Partial dentures. This option of the fixed prosthesis is preferred in case of partial edentulism when several teeth are missing but abutment teeth are still present.
  3. Microprostheses. Miniature artificial teeth are fixed if 1-2 teeth are missing in the oral cavity. Immediate or butterfly prostheses can be referred to as microprosthetic construction.

The type of manufacturing material classifies the following options for removable dentures:

  • Nylon. Such material is completely biocompatible and suggests maximum aesthetics.
  • This type of removable denture can be manufactured from the following materials: acrylic, Spofadent, IvoBase, Vertex, and Deflex.
  • With metal fasteners (clasp).

The type of attachment can also classify removable dentures. There are:

  1. Completely removable dentures. These products are fixed in the oral cavity using the vacuum effect when negative pressure is created between the palate or gum and the prosthetic bed.
  2. Overdenture restoration. Such prostheses are supported by the remaining teeth while using special locks.
  3. Implant-retained over-denture restorations. Such constructions are indicated in the case of missing teeth (edentulism). Before fixing the prostheses, 2 to 6 titanium pins are inserted into the jaw bone, onto which the prostheses are subsequently fixed.

Независимо от разновидности съемных протезов, любая конструкция состоит из седловидной части (базиса), опорного элемента (каркаса), а также самих зубов, изготовленных из металлокерамики, керамики или пластика.

Regardless of the type of removable dentures, any design contains a saddle (base), a supporting element (frame), and the porcelain fused metal, ceramic or plastic teeth.

How Removable Dentures Are Attached

Several factors influence the way the removable dentures are fixed. Such factors include:

  • degree of mobility, size, and position of the tongue in the oral cavity;
  • some anatomical features of the prosthetic bed, palate, and alveolar ridge;
  • lack of dental precontact.

The following types of fixation methods are used to fix removable dentures in the oral cavity:

  1. Attachments or locks. This fixation method is not often used when installing removable dentures, but it is often used when installing fixed structures. Attachments can be used for partial edentulism when there are no more than two teeth in the patient’s mouth. The patrix or fitting part of the attachment can be located in the root or crown part of the abutment tooth.
  2. Clasps and hooks. This type of fitting is used mainly for removable prosthetics, and the fixing devices and the dentures are made of similar material. Acrylic, polyurethane, and nylon dentures have fixation devices, while removable clasp dentures are equipped with metal hooks.
  3. Suction cup or flexible dentures. This method of attachment is used when installing a complete denture or overdenture. The attachment mechanism of such devices is based on the adhesion or natural vacuum effect of suction.
  4. Implants. Removable implant-retained dentures can be fixed by a bar or ball attachment.

New Generation of Removable Dentures

Dentures of the new generation mean dental constructions that are attached to a particular base. The main advantages of such designs include convenience and ease of wearing, strength, small size, and aesthetic appearance. The critical difference is the type of attachment since they are fixed mainly on the alveolar process without involving the palate. The new generation of removable dentures includes telescopic, clasp, and acrylic designs, which are most often attached to abutment teeth.

How much Does Overdenture Restoration Cost?

The price of overdenture restoration directly depends on the following factors: the method of prosthetics, the complexity of the clinical case, the denture material, and the type of attachment. The estimated cost of removable dentures is given in the information table format.

Reviews on Removable Dentures

Removable dental prosthetics have both advantages and disadvantages, which must be considered before choosing a particular method for restoring dentition. The benefits include the relatively low cost and ease of placement. The disadvantages of this type of prosthetics are a loss of the jaw bone tissue, a high risk of prosthesis falling out, and psychological discomfort of which about half of patients with removable dentures complain.

Alternative methods of prosthetics such as “All-on-4”, “All-on-6” help gain a beautiful smile and restore chewing function. Compared to the standard process of implantation, which provides for installing an artificial post for each tooth separately, the prosthetic structure is retained by four fused implants in the case of the “All-on-4” concept. If there are no contraindications, prosthetics can be performed in a single visit to the dentist.

A similar procedure is performed using the All-on-6 procedure when six implants retain the prosthetic structure. Both methods are safe, low-traumatic, and are not associated with a high risk of complications. It is possible to place a tooth implant in Kyiv performing an All-on-4 or All-on-6 procedure, immediately or in several stages, at an affordable price with complete restoration of the dentition. All-in-4 and all-in-6 procedures are the best alternatives to both removable dentures and conventional implants.
