What are Overdenture Attachments ?
Overdenture attachments are a type of attachment of a removable or partially removable prosthesis. They are a castle structure consisting of two elements – a matrix and a patrix. The first is installed in the prosthesis, the second – in the abutment tooth and crown, after which both parts are snapped into place, providing a secure fixation. Attachments in dentistry by their principle resemble the familiar push-button mechanism.
What Types of Attachments are There?
Intracoronal – hidden inside the abutment tooth or crown, so they are not visible from the side.
Extracoronal – attached from the outside, which provides the necessary mobility.
Root posts – Placed directly on the root of the tooth.
Crossbars – use a kind of small valve.
Anchoring (spherical) – the patrix is made in the form of a ball.
Rail – the male has a T-shape, which increases the friction force.
Rod (bar) – implants are interconnected by a transverse bar, under which a groove is provided in the prosthesis.
Pro’s & Con’s of Overdenture Attachments
The overdenture attachment has quite a few advantages. Among them:
- Compactness and lightness in comparison with traditional removable versions on a plastic base – This shortens the period of getting used to, provides greater comfort, does not affect diction or taste;
- Invisibility – Outwardly nothing betrays the presence of artificial teeth, even distribution of the load when chewing;
- A small number of contraindications – in many cases, clasps can be used when the installation of implants is impossible
- Cost – The price of a Overdenture Attachments prosthesis for the upper or lower jaw depends on the number of teeth being restored. On whether it will be one- or two-sided, from the model of locks; the complexity of the work, etc.
The disadvantage is that, in contrast to the overdenture attachments technology, in order to fix it, the abutment teeth in any case have to be ground or crowned on them. On the other hand, this solution provides better fixation and makes the prosthesis completely invisible. It is not easy to break an overdenture attachment, but if it does happen, it can be problematic to fix it.
Indications and Contraindications
In many cases, the main indication is the inability to install implants. For example, due to malocclusion, periodontitis or bruxism. Most often, clasps are used when the dentition lacks several adjacent teeth on one or both sides of the dentition.
Accordingly, in this case, they speak of a one- or two-sided prosthesis. Installation is also permissible when it comes to one tooth. There are relatively few contraindications for this technology. The main thing is the absence of teeth that could play the role of supporting ones, or pathological changes in their tissues. In some cases, the shape of the gums, insufficient depth of the bottom of the oral cavity (when it comes to the lower jaw) or other anatomical features do not allow the use of such constructions. There are also temporary contraindications such as untreated inflammatory diseases in the mouth.
For whom are the Overdenture Attachments Suitable?
This variety has certain indications. Those who have:
- No 3 or more teeth in a row in the anterior or lateral part of the dentition.
- Impaired diction and chewing due to the loss of one or more teeth
- Revealed diseases of the periodontal tissues, for example, periodontitis
- Enamel is subject to increased abrasion
It is difficult to overestimate the Overdenture prosthesis on attachments. It copes perfectly with the main tasks of prosthetics, ease of use and high aesthetics. Top Implants Ltd. attachments have a high reputation among orthodontists and have all the necessary qualities for a successful prosthetics.
