Full Arch Removable

When all teeth are missing in either upper or lower jaw, it is possible to replace these with either a full arch bridge or a denture attached to implants. In this case, the number of implants required is fewer than the number of missing teeth.

The first stage is the placement of a suitable number of titanium implants to support the removable bridge (overdenture). Typically this may be two to four implants in the lower jaw and four to six implants in the upper jaw. These implants will remain unloaded at gum level for up to 4 months. During this time, the bone will form a bond with the surface of the implants.

The final stage is the attachment of permanent abutments (posts) to each implant, and sometimes also a metal bar connecting the implants, followed by construction and insertion of the removable bridge. With techniques that ensure optimal size, shape, colour and fit, this removable restoration, sometimes called an “over-denture” will be designed to complement your facial characteristics while providing the support needed for a natural appearance of the lips.

Removable appliances to replace all teeth on the jaw

These appliances essentially are dentures. However, unlike conventional dentures, these are retained in the mouth not by suction to the gums but by an attachment to the implants. The simplest of these is a full lower denture retained over two implants. In many cases an existing denture can be used and modified to allow retention to the implants. The maintenance that is required for these dentures usually involves yearly replacement of plastic retainers inside the denture and necessary repairs and cleaning of the denture itself.

These are so called implant-retained dentures where implants are employed for denture retention only. The support for the denture is still offered by the gums that bear all the load of chewing. As it is important to maximise the area of that support, the denture has to be fully extended. In other words these dentures are not necessarily smaller than conventional full lower dentures.

The main advantage of these dentures is dramatically improved retention. Even in situations where a conventional denture could no longer stay in place and jumps out of the mouth, anchorage with dental implants offers reliable retention and security. This is also the least expensive solution to replacing all missing teeth on the lower jaw. The downside of this design is the fact that it is still a full denture. By virtue of their bulk, full dentures can be very uncomfortable. As was mentioned before, they rest on the gums and food could get between the denture base and the gum causing some sore spots.

The next removable design is a full denture retained and supported by four or six implants. Unlike the previously discussed construction, these dentures are not only strongly retained but they are also fully supported by the implants. This allows a dramatic reduction of the denture base. In the case of the upper jaw, the roof of the mouth could remain uncovered by the denture therefore significantly reducing gagging and improving the ability to enjoy food.

The dentures could be made out of acrylic resin or have a metal substructure that would increase their strength and reduce bulk. The dentures could be directly attached to the separate implants or as an alternative there might be a bar permanently joining the implants in the mouth. This bar serves to retain the denture. Similar maintenance is required for implant-supported dentures: replacement of attachments, cleaning and repairs.
