Abstract
Patient: A 71-year-old man complained of articulation disorder caused by poor retention of the upper and lower complete dentures. Both maxillary and mandibular residual ridges showed severe resorption. The dentures had short base borders and poor retentions, and were sway with mandibular functional movement. First, I planned to improve the retention and mandibular position of his dentures by repairing his dentures. When I confirmed to make a good retention and an appropriate mandibular position, I started to make new dentures, and then set them.
Discussion: Evaluation before and after treatment showed recovery of articular function. The new denture, which has suitable tongue space, made the tongue movement area during speaking wider. This might result from the patient acclimatizing to a new condition.
Conclusion: New dentures showing stable retention and good articular function were not sway during functioning or articulation, and the patients articulation became clear.
