Last few years, the clasp prosthesis, or also sometimes it is called bugle, is in the lead position (among removable prosthesis). So what is it? Clasp denture is based like arc, and in contrast to other prosthesis, it uses for support not only gum, but also patient’s teeth. Thanks to it, bugle is more sensitive to gum, also there is considered, that clasp prosthesis can supply masticatory load more naturally. Thereby clasp denture wins traditional laminar removable dental prosthesis. In addition, we can to add that clasp denture looks compact, is comfortable in using and long-lived. In dentistry is used clasp denture with telescopic fixation system and bugles with micro-locked fastening (clasp denture with klammers and locks).
Clasp prosthesis with klammers is made to teeth, that’s why is fixed the best way on it, and thanks to elastic, it doesn’t spoil enamel. The one minus is the metal details are visible during smile.
The second way of clasp fixation is with help of locks, which are fixed on abutment teeth, it’s more durable. The most important in lock fastening is its invisible, and that it is hided in clasp denture. Everything is supplied by high modern technologies – high-precision casting and special materials, and of course high skilled specialists. Clearly, that there is most desirable is last variant, though you have pay more, as the making process of clasp denture is hard and difficult!
The advantages of lock fastening is:
- Higher precision than with klammers;
- Higher esthetic quality of prosthesis and shorter period of patient’s adaptation to such prosthesis;
- Availability of standard interchangeable compound parts;
- The prosthesis is long-lived (in average is 7-10 years).
- Ability to change matrixes and repeated activation;

1 - is fist part of lack (patrix), it is on removable construction (on crowns, bridges and so on) |

On the 1st pic. – It is silicone matrix. It is second part of attachment. Exactly there is fixed patrix.
On 2nd pic. Is showed linked lock:
1 - is crown (which will be cemented on tooth).
2 - patrix
3 - matrix
4 – framework of clasp denture |
|
|
1 – Metal-porcelain dental bridge with attachments.
2 – Attachment (lock) – patrix
3 - Attachment (lock) – matrix.
4 – Taking area is free. That’s why diction is usual, in contrast to using of partial removable prosthesis with plastic palate.
5 –metal part which join right and left parts of prosthesis (the partial removable denture has plastic plate)
6 – dental basis, where the plastic teeth are fixed. |
|
|
1 - Metal-porcelain crowns which will be cemented.
2 - It is arc, which joined right and left parts of dental prosthesis, is set inside behind lower teeth.
3 - patrix
4 - matrix
5 - klammer |
|
|
1 – Removable part of construction.
2 – Fixed part. |
Opt for clasp prosthesis depends on different factors, and the defined factor is price. That’s why laminar dental prosthesis is cheaper, than follows classic clasp denture with klammers and then high-tech clasp denture with attachments (locks).
