How to solve the problem of unclear pronunciation with full dentures? When wearing dentures for the first time, especially full dentures, the range of tongue movement is restricted and temporary pronunciation disorders can occur. If the denture is not well fixed, the abutment is too thick, too large, or the teeth of the denture are positioned to the side of the tongue, the effect on pronunciation is more obvious. These problems should be modified in time. What is more important is to rely on the patients themselves to gradually adapt, adjust, exercise, and consciously practice the often unintelligible sounds, most of them can quickly restore the normal pronunciation function. The solution to the articulation disorder method depends on its cause. If it is because the palatal surface of the abutment is too smooth and the lingual surface of the anterior teeth is too smooth, the anterior part of the maxillary abutment can be formed into the form of palatal folds and incisal papillae. If the abutment is too thick it can be appropriately ground thin. What should I do if my full denture falls out when I open my mouth to speak or yawn? This is due to the fact that the edge of the abutment is too long and too thick, and the cushioning of the edge of the abutment in the labial, buccal and lingual ligatures is not enough, which affects the activities of the surrounding muscles: or the shape of the polished surface of the denture is not good. In this case, we should use symptomatic methods such as grinding and changing the edge of the abutment that is too long or too thick, cushioning the abutment in the ligament area, forming the proper shape of the abutment polished surface, or appropriately grinding away part of the buccal and lingual surfaces of the artificial teeth to reduce the width of the artificial teeth. What should I do if my complete denture tends to dislocate when I eat? When chewing food, the denture is easily dislocated, which is caused by interference with the cusps of the teeth and imbalance of the bite, causing the denture to buckle and destroy the edge closure. In the mandibular molar posterior cushion area, the thick base is in contact with or close to the base of the posterior edge of the maxillary tubercle, which can also cause poor retention during chewing. In addition, when the maxillary dentition plane is low, the contact between the posterior edge of the maxillary and mandibular abutments when the mandible is extended forward will cause the anterior part of the mandibular denture to buckle and dislocate. In this case, selective grinding and adjustment of the denture should be performed to eliminate premature contact and interference of the cusps, or the edge of the abutment should be ground short or thin.
