Let’s learn about how to install fixed dentures.

How to install fixed dentures?

Prepare

1. According to the number of missing teeth. The abutment teeth and the number of abutment teeth are selected based on the position, relationship, morphology, tissue structure and periodontal supporting tissue conditions.

2. Check whether the tooth extraction wound in the edentulous area has healed, the size of the gap, the alveolar ridge and oral mucosa, etc.

3. The crown of the abutment tooth should be tall and the root should be long. If there is tooth or periodontal disease, it needs to be treated first. Pulpless teeth should undergo complete root canal treatment.

4. The occlusal relationship should be basically normal. If the abutment teeth are tilted, displaced, or the opposing teeth are elongated, twisted, or misplaced, it is necessary to adjust the grinding or change the design of the retainer.

method

1. Preparation of abutment teeth: With reference to tooth defect restoration, tooth preparation should be performed according to the type of retainer. It is required that the corresponding axial surfaces of all abutment teeth are parallel to each other, without undercuts or slightly to the sides or with the cutting ends converging 2o-5o, so as to obtain a common positioning path for each retainer. At the same time, attention should be paid to enhancing the retention force of the retainer.

2. Impression and molding: The impression must be accurate, complete and clear. For both cast fixed bridges and metal porcelain bridges, a double-layer silicone rubber impression method is used to take an impression of the entire dentition, which is then cast with hard plaster and then formed into a removable model with a mold pin.

3. Fixed bridge production: usually completed in the technician room.

4. Trial-fitting of fixed dentures: The initially polished retainers are tried on each abutment tooth respectively. The retainers are required to fit correctly and tightly with the neck of the abutment tooth, with appropriate edge extension, good adjacent relationship, coordinated occlusion, no tilting and good retention. If there are any problems, they can be polished and bonded after being dealt with accordingly. The metal porcelain bridge is tried on before glazing, and the shape is trimmed and the bite is adjusted before glazing and bonding.

5. Doctor's instructions: Instruct the patient to fast within 2 hours after bonding, and not to chew hard food within 24 hours without the bridge. Make an appointment for a follow-up examination if necessary.

The above is an introduction to how to install fixed dentures. After understanding it, we will be able to consider the size of fixed dentures. In addition, when we have problems with our teeth, it is best to listen to the doctor's advice to choose dentures that suit us, and we must also pay attention to oral hygiene after installing the dentures.
