RPD Framework - Linguoplate (Lingual Plate) Major Connector
Posted on 11/02/2011
While the lingual bar is the recommended design for the mandibular arch, it is not always possible or indicated. Specifically, if the patient exhibits any of the following features, a lingual plate is indicated:
1. High floor of the mouth (i.e. less than 7mm from the gingival margin)
2. High Lingual Frenum
3. Inoperable Lingual Tori
4. Future extraction of anterior teeth is likely
5. Posterior teeth are missing and additional retention is needed
The lingual plate has a lingual bar but extends to cover the lingual side of the indicated teeth up to the middle third of the tooth. As such, it provides additional support for the framework. However, it also introduces two important potential complications:
1. Oral Hygiene: It is difficult for the patient to clean the lingual side of the teeth and food tends collect in any crevices
2. Caries and Periodontal Problems: Food collection can lead to caries or periodontal problems.
There are two very important design specifications for the lingual plate:
1. Lingual plating does not extend superior to the middle third of the teeth
2. Superior border should be scalloped and thereby extending into the interproximal contact areas.
