The adhesive bridge – a good solution with minimal tooth defects?
An adhesive bridge, also known as Maryland or adhesive bridge, is a modern and solid denture. Especially with healthy neighboring teeth, minor tooth defects or single tooth loss, the adhesive bridge offers a good opportunity to close single tooth gaps and treat the healthy neighboring teeth only minimally invasive. Read more about the adhesive bridge here.
What is an adhesive bridge?
Bridges consist of bridge piers and bridge piers. The adhesive bridge is a three-limb bridge: two bridge abutments delimiting the tooth space and a bridge element. This bridge member closes the single tooth gap.
The special feature: An adhesive bridge is attached using an adhesive.
While with the usual dentures your teeth are ground and thus a large amount of tooth hard substance is removed, with adhesive bridges sticking materials are used. The tooth hard substance is removed only minimally invasive. Subsequently, the adhesive surface is roughened by means of acid etching technique. By means of a special dental adhesive, the adhesive bridge can then be incorporated.
Depending on the situation, a distinction is made between single and double-leaf adhesive bridges. Single-leafed individuals are only interlocked with one abutment tooth, while two-winged adhesive bridges are glued to two abutment teeth.
An adhesive bridge is only possible in special cases
The use of an adhesive bridge is only possible in special situations:
- The bridge pier teeth must be caries free
- In contrast to small area fillings, large fillings are a contraindication for adhesive bridges
- Sufficient enamel is needed to create an adhesive bond
- Parafunctional loads, such as crunching or pressing, are unfavorable in the case of adhesive bridges because they release the bonded dentures more quickly
- In the anterior and posterior region of the maxilla, adhesive bridges are only suitable for single tooth gaps
- If several teeth are missing, this is often considered a contraindication for adhesive bridges. In the lower jaw further margins of up to four anterior teeth are possible. However, the arcuate progression of the row of teeth and jawbones often present a problem for these wide margins in adhesive bridges as they are rigid in course
When is an adhesive bridge commonly used?
- Gum disease: In adults, gum disease and associated single tooth loss are the reasons for the use of adhesive bridges
- After orthodontic treatments: In children and adolescents, adhesive bridges are more frequently used after orthodontic treatments, which have led to minimal remaining tooth spaces. It is important to use double-leaf adhesive bridges only after completed jaw growth. A complete maturation and adjustment of the teeth is thus not prevented.
- As a long-term temporary: Also as a long-term temporary restoration before definitive implantation for a permanent gap closure, an adhesively secured denture with adhesive bridges is possible. It should be noted here that the bone growth in boys takes significantly longer than in girls. While bone growth in girls is around 17 years old, it is only 21 years for boys. Thus, an implantation only makes sense after completing the jawbone growth.
What are the advantages of an adhesive bridge??
Successfully adhering adhesive bridges place high demands on precision, integration, technical production in the laboratory and also on your individual oral hygiene.
The advantages of an adhesive bridge are:
- the minimally invasive hard tooth substance loss of the bridge abutment teeth
- the avoidance >How is the treatment with an adhesive bridge??
Despite minimally invasive surgery, you need to prepare for multiple treatment sessions.
Step 1: Production of planning models
Step 2: Treatment of your teeth
Then your dentist treats your teeth. The tooth surfaces on the palate are minimally ground in a so-called insertion direction. It requires a parallel insertion direction from both bridge piers, so that as few forces as possible from different directions when loading your new dentures can act. Early loosening of the adhesive bridge is thus avoided.
Step 3: Impression of your teeth
This is followed by a definitive impression of your teeth prepared by the dentist so that the laboratory can produce the dentures. Tooth color and tooth shape are individually adapted to you.
Step 4: Control
In another session, your dentist will check the fit and adaptation of the tooth color to your natural teeth. Subsequently, the adhesive bridge is adhered by means of acid-etching technique.
Regular and intensive oral hygiene provide a perfect and also the most important basis for long-lasting hold of your new adhesive bridge. Regular checks at your dentist are also not negligible.
