Although there is evidence that covering teeth by parts of a denture may damage teeth and the periodontium, the lingual plate is still common in clinical practice in many countries. The aim of this study was to compare the lingual plate and lingual bar type major connectors in the lower jaw as reflected in the literature.
Materials and methods
A literature search was carried out in PubMed for articles focusing on the possible effects of lingual plate major connector on the oral environment. Case and technical reports were excluded.
The lingual plate which covers the soft tissues of the periodontium and the hard tissues of teeth results in increased plaque accumulation, development of caries and gingivitis, which in turn results in periodontal breakdown. The lingual plate functions as a barrier to saliva circulation, decreasing selfcleaning of teeth on the covered surfaces. Wearing a linguoplate denture increases the likelihood of halitosis, corrosion and metallic taste. Patients have to wear a large volume of metal, which may cause difficulties in speech and may impair touch and form perception. The lingual plate may not satisfy the patient's esthetic expectations either. These issues are uncharacteristic for the use of lingual bar connector for removable partial denture.
A lingual bar should always be used in the lower removable partial denture, thus providing a hygienic denture design, comfort and esthetic appearance.
