Partial denture is a suitable treatment to replace several teeth that are amiss in an arch. Partial dentures are detachable appliances which are held in position with metal clasps which fit around some of the remnant innate teeth. The clasps are shaped alike the letters C, Y and I.
6 Problems With Partial Dentures
Natural Wear And Tear
Partial dentures constantly bear the brunt of frequent gnawing that places sizeable pressure on the components, namely the metal clasps and the pink-coloured acrylic.
Many individuals who have been using partial dentures for protracted periods of time (such as five or more years) report cracks and ruptures developing in the acrylic section.
Several long term wearers have also complained of broken metallic clasps, termed as precision attachments, which lock the denture in position for an innate feel.
As they are quite thin pieces of metal, hence, one needs to be wary about not munching on any hard consistency victuals since it increases the likelihood of cracks developing in them.
With passage of time a wearer could even start to grind on the partial denture with his/her innate teeth, thus leading to their occlusal parts (the biting or grinding surfaces) being impacted.
Ill-Fitting Partial Dentures
By far, the most prevalently encountered issue with partial dentures is that they are rather loose due to which they can be slightly moveable. A partial denture, in essence, is designed to be non-rigid as it is reliant on compactable tissue for supporting it or it hooks around the borders of your teeth. Since it has to be removable, thus the dental practitioner always designs the appliance accordingly.
In regards to regular functionality, the partial denture ought to fit in a manner that user is incapable of dislodging it by manually tapping to athwart it. In addition to this feature, complete ceding of the partial denture against the oral tissue also holds importance.
In case the partial denture which is resting on a tooth that is held up by a metallic or plastic part doesn’t allow it to totally cede against the tissues then considerable pressure would be exerted on the concerned tooth.
In such a situation, it would partly replicate the action of an orthodontal device which works by moving tooth to pre-decided location and then holds it in place till solidification occurs. The partial denture would then be moving the tooth. But once the denture is removed then the teeth is moved back.
Regular removal and re-attachment of the partial denture in the mouth coupled with incomplete ceding can result in the wearer experiencing considerable soreness in that tooth which can also loosen due to such repetitive back and forth rocking against it.
A number of patients who wear partial dentures are self-conscious or slightly disconcerted due to the apparent look of metallic clasps that are necessary for preserving structural form and positioning.
Clasps of metal have been found to draw calculus and plaques that innately accrue on teeth. Thus, a person using partial dentures would have to go that extra mile in regards to maintaining optimal oral hygiene.
Strain On Adjoining Teeth
Oftentimes, partials could augment stress on the adjacently placed teeth which is causal to their breakdown and augment susceptibility to dental caries as well as gum disease.
