PADDING OF DENTURES


Padding of dentures

Prosthetic work is intended to replace teeth that have been lost due to numerous processes, whether carious or traumatic in nature, and can also be added to teeth that are still present in the dental arches but have undergone changes.

The prosthetic pieces are designed in the dental surgery, where the patient goes through several stages before the final result is achieved, but they are made in the dental laboratory. There are several types of prosthetic work.

Types of prosthetic work

Single crowns – these are added to a tooth that has a partially or totally destroyed crown and are intended to restore both the morphology and function of the affected tooth.

Unitary crowns may be made entirely of metal or ceramic or may be a combination of these two materials. The patient chooses, together with the doctor, the optimal treatment option according to aesthetic and material considerations, but also according to the stresses that arise in the area where the prosthetic work is added.

Dental bridges – applied when at least one dental unit is lost from the arch.

Bridges are added to the patient’s healthy, solid teeth and require a greater sacrifice of tooth substance.

Skeletal prostheses – these are fitted when the back teeth are missing and are bonded to the front teeth.

Full dentures – are applied when the arch is missing teeth.

They rest only on the soft, gum tissues and through these, on the hard, bony, underlying tissues.

Prosthetic work can deteriorate over time but changes can also occur in the prosthetic field.

These are mainly due to the continuous remodelling of the underlying bone.

Therefore, over time, especially in the case of total prosthetic work, a series of adjustments must be made, otherwise the work becomes unstable, tilting in the oral cavity.

It can come loose when speaking or chewing and can cause aesthetic, functional and psychological problems for the patient.

Lining of full dentures is indicated when there is no longer a parallelism between the prosthetic work and the field to which it has aggregated.

Lining consists of adding a new layer of material to the mucosal surface, i.e. the surface that comes into contact with the prosthetic field.

Counter-indications

Lining is not indicated in the following situations:

If the intermaxillary relationships are not correct, lining will not solve the fitting problem. The ideal solution would be to reshape the prosthesis in harmony with the prosthetic field situation.

Inadequate fit of the prosthesis edges – the edges must fit firmly and tightly to the prosthetic field. If this condition is not met, the denture will come loose or cause damage to the oral mucosa.

Old dentures where the materials have deteriorated must be replaced. Worn, old, aged materials are susceptible to fracture and debris.

Dentures that have been modified several times over time may not respond favourably to further repair.
