dental bridge / temporary bridge
Tooth loss is an unpleasant experience as the area around the teeth has a huge impact on a patient’s appearance. The solution: a dental bridge. It closes the tooth gap and enables the patient to confidently participate in daily life. Find out here when a dental bridge makes sense, what types there are and how the treatment of fixed dentures works.
What is a dental bridge used for?
A bridge is a dental prosthesis that is used to close a tooth gap, which can include one or more teeth. It not only improves the appearance of a gap in the teeth but also restores the chewing function. Alternative dental prostheses are the placement of an implant and removable prostheses.
Dental bridge: what types are there?
There are different types of dental bridges in the dental care of a tooth gap with a bridge. These dental bridges can differ according to the type of materials used, the size or shape and the type of attachment to the adjacent teeth. The cost of a dental bridge varies accordingly.
In contrast to the suspension bridge, the bridge element of the base bridge rests on the alveolar ridge. As the name suggests, this dental bridge is used as a standard restoration.
A suspension bridge is characterized by the fact that the pontic itself does not rest on the jaw. This type of bridge is sometimes used in the invisible molar area.
A cantilever bridge is used if there is no longer a natural tooth on one side after the tooth gap or if grinding a healthy tooth would sacrifice too much substance. That is why there is no need for a pillar to be attached on both sides. Instead, two pillars are used side by side on one side. For reasons of statics, however, only small spans can be bridged, and, as a rule, only one tooth can be replaced.
Composite bridge (also hybrid bridge)
A composite bridge is a composite of different types of bridges; this can only refer to the materials used. In most cases, however, a composite bridge refers to a dental bridge that uses different bridge abutments (e.g., a natural tooth and an implant).
In order to protect the neighbouring, healthy teeth, no crowns are used as anchors for the dental bridge, but the bridge is glued to the natural teeth. The adhesive bridge is alternatively also known as the Maryland bridge and is mostly used in children or adolescents who cannot “block” multiple teeth for growth reasons.
While the bridge anchors in a normal dental bridge consist of crowns, in an inlay bridge, the same is attached to the natural, adjacent tooth by inlays. Inlays are fillings made of ceramic or gold made in a dental laboratory.
A removable dental bridge is a special form of this dental prosthesis and can be removed by the patient for cleaning. Apart from this special feature, however, it does not differ from other dental bridges.
What material is a dental bridge made of?
Since bridges as dentures usually require a crown as an anchor, the same material is used in the manufacture of dental bridges as in the manufacture of crowns.
A metal alloy is often used in the non-visible area. In the visible area, a metal alloy is usually partially or completely coated with a ceramic material (partial/full veneer).
To maintain the teeth’ natural aesthetics, even more, dental bridges can also consist exclusively of ceramic. Compared to ceramic, metal is more stable. However, the quality of all materials used for dental bridges has proven itself.
Dental bridge: this is the treatment
The first appointment: grinding the teeth
During the first appointment, the neighboring teeth are ground and prepared similarly to a crown’s insertion. For this purpose, any existing caries must be removed and, if necessary, a top-up must be placed. The pillars of the dental bridge must be parallel to each other so that the bridge can be used. In addition, the tooth color for the manufacture of the tooth-colored bridge is determined during this appointment. Impressions are also taken, and temporary dentures are used to protect the teeth.
The second appointment: the interim rehearsal
The second appointment is for the interim trial of the dental bridge, the so-called framework trial. Here, the accuracy of the fit of the dental bridge is checked, and it is ensured that it does not trigger a feeling of tension. The dental bridge is then completed by the laboratory. Further processing includes, for example, veneering the dental prosthesis with ceramic. In order to reduce the risk of a change in the fit of large dental bridges, another intermediate try-in at the dentist, the so-called raw fire try-in, may be necessary.
The third appointment: the incorporation of the bridge
At the third appointment, or later depending on the size of the dental bridge, the bridge is finally incorporated, which is analogous to the insertion of a crown. Thus, the crowns, i.e., the anchors, are inserted and firmly glued if the fit is accurate. Particular attention is paid here to the accuracy of fit with the abutment teeth and the adjacent teeth, as well as the absence of tension.
During a routine check-up, the integration of the dental bridge and its height is checked again.
What are the advantages, disadvantages and risks of a dental bridge?
Advantages of a dental bridge
Long shelf life: 10 to 20 years
Less time consuming to manufacture than prostheses
Disadvantages of a dental bridge
Adjacent, healthy teeth must be ground down> good tooth substance is lost
Risk of infection from grinding teeth: tooth enamel is attacked
WHAT IS A TEMPORARY BRIDGE?
In addition to a clasp prosthesis, a temporary bridge can also be used as an interim tooth replacement. This is used temporarily to close tooth gaps in neighboring teeth that need a crown until a final bridge is inserted or a final implant restoration is carried out.
FIXING A TEMPORARY BRIDGE
As an alternative to the clasp prosthesis, a temporary solution can be attached by gluing (adhesive bridge or Maryland bridge, adhesive bridge ). In this case, the temporary arrangements will be made by the Berlin dentist, Dr. Seidel, made of high-quality plastic. Temporary cement, which often contains a drug (e.g., zinc oxide eugenol) to soothe a toothache after grinding the tooth or an inflamed tooth nerve, ensures reliable hold. In addition to alleviating any toothache that may occur, this special luting cement also makes it easy to remove the temporary when it is no longer needed. An adhesive bridge means a stable fit but is primarily suitable as a temporary solution in the anterior region and is comparatively cost-intensive.
DENTAL BRIDGE AS A LONG-TERM TEMPORARY
While a dental bridge used as a short-term temporary is mostly made of plastic, a bridge to be used as a long-term temporary is mostly made of metal. A bridge is mostly used as a long-term temporary restoration when neighboring teeth are in great need of renovation, bone augmentation is to be carried out at the missing teeth location, the occlusion is corrected, or extensive periodontal treatment is carried out.
WHAT IS THE IMPORTANCE OF A TEMPORARY IN IMPLANT RESTORATION?
Implants require a certain healing time (implant healing). Therefore, the provision of a temporary restoration is very important in the transitional phase because aesthetics and chewing function should also be ensured for the patient during this time. In addition, the healing implant is protected from overload.
WHAT ARE THE REQUIREMENTS FOR A TEMPORARY SOLUTION?
Before the restoration with temporary implants, perfect contouring of the soft tissue by the Berlin dentist Dr. Seidel necessary. This means the ideal adaptation of the temporary restoration for the respective patient, on the one hand, for aesthetic reasons and, on the other hand, from a psychological and functional point of view. The contouring is an important aspect of the optimal rehabilitation of implant patients. The provisional is fixed immediately and can be loaded. It is often used as a template for a later implant bridge.
WHICH OPTIONS FOR TEMPORARY IMPLANT RESTORATION CAN BE USED?
In the case of temporary implant restoration, on the one hand, immediate loading by means of a temporary crown and, on the other hand, the use of short-term implants (interim implants), which temporarily carry a temporary bridge, can be used. The fabrication of a fixed temporary implant is very important in the edentulous upper jaw even after the implants have healed and after the late restoration so that further therapy can be planned reliably. Here, too, the dentist must pay attention to the optimal contouring of the soft tissue and the position of the teeth in order to achieve satisfactory functionality and aesthetics for the patient.
Immediate loading does not apply to temporary implants for single-tooth restoration. The dentist uses adhesive bridges or interim prostheses due to the load conditions, but these are also decisive for the subsequent implant appearance.
