It is the type of dentures that is applied when there are many missing teeth and when fixed prosthesis cannot be done. Hidden clips are placed inside the cavities carved inside the teeth.
Stages of precision attachment partial dentures are the same as stages of partial dentures. The dentures are prepared in 5 sessions as including impressions and various trials, on the average. For 5 sessions, 2 weeks would be sufficient.
In precision attachment partial dentures, there are sensitive parts which are placed in the cavities. When they are newly made, although they are too tight when placing and removing them, in time they can be placed and taken out more comfortably and easily. They should be placed and taken out with care.
Just like partial dentures, this type of dentures have metal parts that pass from under the tongue at lower jaw and from palate at the upper jaw. Because of these parts that are on the prosthesis, it can be difficult to get used to it in time. But after a certain time, many patients used these prosthesis just like their own teeth.
Cleaning of precision attachment partial dentures are just like cleaning complete dentures.
As precision attachment partial dentures are made by getting support from soft tissue and existing teeth, no problems are seen regarding their adhesion capacity. Cutting, biting and grinding functions can be done easily.
Parts of the precision attachment partial dentures which are placed in the cavities avoid for the prosthesis to get out its place. Therefore, they don't move while eating. In time loosening can occur with the rubber parts of sensitive connections. In this case, rubber parts can be easily changed.
As the parts giving support to precision attachment partial denturesare placed in the prosthesis, they are more aesthetical than prosthesis with hooks.
In addition to paying attention to the particulars relating with the usage of complete dentures, it is required not to damage the sensitive connection parts when placing or removing them. Process of placing or removing should be done carefully. After making sure that the denture is exactly placed, jaw should be closed. The denture should be placed without closing the jaw. Or else, damages can occur at precision attached parts.
Just like the case with partial dentures, the base section and teeth can be easily repaired for precision attachment partial dentures. If the rubber parts within precision attachment get loose, they can be changed but if precision attachment parts are broken, it is difficult to repair them.
Just like the case with partial dentures, even though it changes depending on the shape and dimension of fracture in the partial dentures, generally it is possible to repair them in 1-2 days.
Just like the case with partial dentures, precision attachment partial dentures can be applied to almost all the patients and they can also be easily applied to patients with diabetics. It can take a long time for the bents and wounds that appear at the end of application, to recover. Besides, as there can be the problem of mouth dryness, it can be required to use special gels and artificial saliva.
Mass of bone tissue is not very important in prosthesis with sensitive connections. As it is a prosthesis done by getting support from existing teeth, number, solidness and dimensions of teeth are important.
First of all, allergy tests should be taken to determine the particulars causing allergy. In prosthesis with sensitive connections, metal and acrylic materials are used. If there is metal allergy, the type of metal causing allergy should be determined and thus, by using a different type of metal, prosthesis can be applied. But if there is allergy for acrylic, it is not possible to use precision attachment partial dentures. In this case, implant-supported dentured can be used.
Prosthesis with sensitive connections can serve for many years, when they are well taken care of and hygiene conditions are provided. Depending on the usage, loosening or breaking can occur on the rubber and other parts of sensitive connections. If teeth providing support are lost, it is required to repeat the prosthesis application.
As precision attachment partial dentures should be placed inside the cavities that are carved, it is required for existing teeth to be crowned.
In partial dentures, there are hooks which are not aesthetic. In precision attachment partial dentures, there are no hooks. For partial dentures, it may not be required to apply a process to existing teeth. In precision attachment partial dentures, process must be applied on existing teeth. For precision attachment partial dentures, there should be at least 4-6 teeth on the jaw. For partial dentures, there are no restrictions. Cost of precision attachment partial dentures is a little more than partial dentures.
If there are many missing teeth, if fixed prosthesis cannot be made by using existing teeth, removable denture (partial denture and precision attachment partial denture) can be applied or dental implant can be placed inside the jaw bone for fixed dental prosthesis. When mobile prosthesis are applied, they cause trauma on teeth as they are placed or taken out or cause melting on jaw bone. Thus, fixed prosthesis is healthiest option applied by placing dental implants inside jaw bone if many teeth are missing.
