Clasp prosthesis is a popular and effective type of prosthetics, aiming to restore the already lost teeth. The demand is due to excellent functionality, aesthetics and performance.
The medical products are of all possible kinds replaced both separate units, and the entire dentition. Due to design features clasp prostheses are supported by the bone tissue, or by treated teeth and it positively affects the optimal distribution of the load during a meal.

Structures designed for the upper jaw are easy to use, they can be put on and off without any difficulties due to the arcuate shape. They practically do not bother during communication and food intake, and attachments are very reliable.
The design consists of the following components:
Musculoskeletal retaining elements are manufactured as one piece or from separate metal wires or elements connected by soldering.
The one-sided design makes it possible to restore the number of teeth and has no jumpers. Such prosthesis is generally fastened by means of attachments (locks). Its components are:
Installation is recommended in the following cases of:
This type of prosthesis (the entire jaw/side) is the absolute solution to the problem if there are contraindications for implantation, and in the absence of several teeth in a row, when the supportive teeth are preserved from only one side. This defect is so-called an end effect, which means an inability to install a bridge prosthesis.
Designs have different types of fixation, which are selected by a specialist according to the particular features of the structure of the jaw and the state of the oral cavity. Clasp dentures are attached with hooks (clasps), locks and crowns with a special telescopic fastening.
Such fastening is used, if the shape of teeth is retained, including those units on which crowns have been set. The hooks are part of the cast metal frame that can reliably hold the medical device in the oral cavity.
At the same time, an optimal load distribution during chewing occurs between the teeth and gums (which supports a clasp). Clasps do not destroy the enamel, as this type of lock is used in the case of installation on implants.
In the lock fastening hooks (clasp) are replaced by attachment (microlocks). This is a completely different kind of attachment and can be displayed in the absence of inflammation, and at enough height to support the teeth.
During the installation of dentures on abutment teeth, crowns with locking parts are set. One part of the locks is located directly in the prosthesis, which locks after installation, and securely fixes the construction.
The advantage of this type of fastening is its complete secrecy – all locks are hidden inside the prosthesis and cannot be seen with an open mouth and a wide smile.
It is the most expensive type of construction, which allows you to securely fix the product. The crown of the prosthesis consists of two elements. One of them is on the prosthesis, the second – on the supportive tooth. Once the construction is installed on a supporting unit, the two elements are fixed firmly and securely.
The design has several functions: connective, stabilizing, supportive. Its location depends on the presence of defects.
The shape of the element is:
The ring arc is a rigid structure consisting of stripes. It is supported by the back and front palatal parts. It is possible when many teeth are absent, and if there are no obstacles to using the arc.
Horseshoe arc provides the evenest distribution of load during chewing of food, and is used for:
The design of a transverse stripe is used in a small length limit and with defects included, and a contraindication for the installation may be inflammation of the palate.
The prosthetic procedure takes quite a long time, requires great skill from an orthopedic doctor and the patient’s patience. Before installing it is mandatory to conduct a complete dental health sanation: a recovery of damaged teeth, cleaning of sediment, caries treatment, cropping of all the inflammatory processes.
After the treatment, the patient’s wishes are specified, depending on the number of remaining teeth a design with the best way of fixation is selected. Next, a cast is made and sent to a lab, where a three-dimensional model of the product is created. Then, grinding of the workpiece, the medical device, ready for installation, is tried on and created.
Such constructions are very durable, and the frame is made of safe and hypoallergenic alloys of gold and platinum, titanium. Due to the high-performance characteristics of the product, it is prior to a plastic prosthesis, which differs in insecure and structural fragility.
Today, this is the best way to replace missing teeth:
The only drawback of the medical device is a sufficiently long period of getting used to it, but temporary discomfort pays off in a long-term service life, the restoration of the chewing function and aesthetics.
After the procedure, the dentist is required to tell all the nuances of the process of adaptation. In the first days, the patient may be concerned about the presence of a foreign object in the mouth, excessive salivation, impaired articulation.
After a week of wearing a gradual adaptation takes place, and the symptoms, causing discomfort quickly disappear. Maximum adaptation period – 30 days, and if the patient continues to experience discomfort, there is a reason to assume that the structure is made incorrectly.
Caring for dentures is not too much trouble. They, as well as healthy teeth, need to be cleaned in the morning and evening. You can remove a prosthesis, if necessary, for example, for more thorough cleaning. With proper care, the medical device will last for at least five years. For comparison, the life of a plastic prosthesis does not exceed two years.
The construction does not allow the bone quickly to degrade. However, progressive atrophy of bone fixation can lead to violating of the fixation, cause the pain and inflammatory processes. Therefore, in order to avoid complications, you need to visit the dentist regularly.
The total price depends on several factors. Depending on the condition of the oral cavity simple and complex designs may be installed. In a complex variant, the amount of the supportive arches increases (instead of one may be several); the increase in the price is affected by the type of locking system.
Locking fixation will cost considerably more expensive because it consists of a set of prices for the locking device and the cost of the metal-ceramic crowns.
Simple design costs in major cities from 440$; in the regions from 310$ to 450$.
Complicated prosthetic – 500$, in the regions from 380$ to 460$.
Construction with fixing on two locks from the German firm Bredent will cost not less than 1000$. The price includes the cost of:
The price of one-sided clasp construction is quite high, depending on the parameters described above, and starts from 600$. The final price is determined by the location and the clinic status, as well as physician qualifications.
Experts believe that the clasp denture is a decent and only alternative to other methods. High-level constructions cope with their mission – the restoration of the chewing function and the creation of a cosmetic effect of a healthy dentition.
Positive reviews and appreciation to patients are an indicator of the demand for dental technology. You can also share your impressions about the procedure of prosthetics in the comments to the article.
