[Application of sublingual bar to removable partial denture of a patient complaining of major discomfort to lingual plate].

PATIENT A 62-year-old man complained of discomfort during insertion of lower removable partial denture (RPD). Existing denture was highly objectionable to tongue and intolerable to wear due to volume and contour of its lingual aspect. The treatment plan included fabrication of an interim denture and altering its shape until it did not lead to discomfort, followed by fabrication of a final denture. Consequently, RPD using sublingual bar was found to be the most comfortable to wear and was fabricated as final denture. The patient was ready to insert the final denture and restoration of masticatory function was accomplished. DISCUSSION In cases with unfavorable anatomic conditions such as a lack of mouth-floor depth, lingual plate should be applied as first choice, and when it is not well tolerated by the patient, sublingual bar should be applied. CONCLUSION Sublingual bar is suggested to be one of the least objectionable major connectors.
