Implants For Denture Wearers

This relates to patients who have no natural teeth left in one or more arches

Implant retained overdentures

Implant retained dentures is when there are generally two dental implants that act as anchors to prevent the denture from moving. They are classified as Implant retained because the denture still is supported by the soft tissues (gums). The two implants can retain the dentures with different attachments.

1. A small bar with clips

2. Ball and o-rings

3. Clips that snap directly on the implants

Implant supported overdentures

Implant supported dentures is when the denture is sitting on 4 or more implants. They are classified as implant supported because the denture sits entirely on the dental implant fixtures and only lightly touches the soft tissues (gums) The implants retain the denture from moving as well as supporting the dentures from hitting the gums. The added advantage is that the more dental implants that are placed the less bone will atrophy and the dentures are more stable.

Advantages of Removable Dental Implant Prosthetic

The advantages of removable prosthetics are several. The most important advantage is that the implants and dentures are much easier to keep clean than non removable options. They are less expensive and easier and less expensive to repair when they break.

Full Arch Dental Implants (Semi-Removable Prosthetics)

See also “All On 4” content for more detail on this option

Semi removable prosthetics means that the prosthesis (the teeth) are non removable by the patient, but can be removed by the dentist if necessary. If this involves an entire arch then usually at least 4 implants are necessary to be able to support the teeth. There are a lot of pressures created with biting and overloading the implants by not having enough of them may cause them to all fail.

There are various materials that can be used when this kind of option is selected. It could be a acrylic denture with acrylic teeth or metal re enforced porcelain gums with porcelain teeth. With porcelain there is a lot more pressure created with biting and so more implants will be needed to support the prosthesis (teeth). The semi removable option is often used when there is a lot of bone loss and extensive areas of gums are replaced in addition to the teeth.
