Use of lingual frenum in determining the original vertical position of mandibular anterior teeth.

STATEMENT OF PROBLEM: There is no accurate method for determining the correct vertical dimension of occlusion in edentulous patients. Preextraction diagnostic casts may facilitate determination of vertical dimension of occlusion. In the maxilla, the incisive papilla is a stable anatomic landmark and can be used as a guide to determine the vertical relation of the edentulous patient. Unfortunately, the mandible is devoid of such a stable anatomic landmark. PURPOSE: This study evaluated the reliability of measurement of the distance between the anterior attachment of the lingual frenum and the incisal edges of the mandibular incisors, on casts, to be used as a preextraction record for determining the vertical position of the mandibular incisors in complete denture patients. MATERIAL AND METHODS: Eighteen dentate subjects (9 men, 9 women; 21-28 years; mean age 23 years) were selected. Four mandibular casts were made from irreversible hydrocolloid impression material in plastic stock trays for each subject. All subjects were instructed to elevate the tongue while the impressions were made. The vertical distance between the anterior attachment of the lingual frenum and incisal edges of mandibular central incisors was measured on the casts. Means and standard deviations of the 4 measurements were calculated and statistically analyzed. RESULTS: The mean standard deviation of the distance between the anterior attachment of the lingual frenum and incisal edges of mandibular central incisors among the subjects was 0.1326 mm (coefficient of variation 1.292%). The distance between the anterior attachment of the lingual frenum and incisal edges of mandibular incisors was relatively stable when the frenum was recorded during function. CONCLUSION: The distance between the anterior attachment of the lingual frenum and incisal edges of the mandibular central incisors can be used on preextraction diagnostic casts as a preextraction record for determining the original vertical position of the mandibular anterior teeth.

A simple procedure for easy and safe deflasking.

When the dough-molding method is used for processing a trial denture, it is often difficult to remove the processed denture from the flasking stone. The palatal and lingual stone portions contribute to this difficulty. This article describes a procedure that uses metal aluminum plates to facilitate the removal of these stone portions. The plates are placed vertically at the midline and in the palatal and lingual stone mixtures during flasking. The plates, which are removed during deflasking, make deep grooves and allow the stone portions to be pried toward the midline without considerable force during deflasking. The procedure is easy, facilitates the deflasking procedure, reduces the danger of damaging the denture base and the artificial teeth, and saves time.

Copying maxillary anterior natural tooth position in complete dentures.

The natural teeth provide the optimal guide for the correct placement of artificial teeth. A stent is made on the patient's maxillary preextraction diagnostic cast. The stent is transferred to the patient's edentulous maxillary cast to help position the maxillary anterior artificial teeth in the same positions the maxillary natural teeth occupied before extraction.
