Abstract
Different types of artificial teeth and occlusal designs can be used in complete dentures. Bilateral balanced occlusion, lingualized occlusion, canine guidance, and monoplane are the main occlusal designs; however there is no agreement on which tooth arrangement is ideal for achieving success in complete dentures. This report presents an alternative for persistent involuntary protruding complete denture wearers through the use of artificial teeth with higher cusps. Due to an old and worn pair of complete dentures, the patient had the habit of protruding. New dentures were made with Biotone artificial teeth and in the trial session, the patient would still protrude. A new set was made with Premium artificial teeth, which present higher cusps. With these dentures, the involuntary protrusion did not occur. From the delivery to the follow-up sessions, the patient stopped protruding.
Highlights
Despite the efforts to reduce tooth loss in the world, edentulism prevails in most countries, presenting higher rates, especially in countries where poverty exists [1]
Long-time use of the same pair of complete dentures might lead to aesthetics impairment, loss of vertical dimension, and reduction of masticatory efficiency [2, 3]
Complete dentures have been used in prosthodontics for over a hundred years, there is no consensus on which tooth arrangement is ideal for achieving success in complete dentures [5, 6]
Summary
Despite the efforts to reduce tooth loss in the world, edentulism prevails in most countries, presenting higher rates, especially in countries where poverty exists [1] In these countries, complete dentures are the primary choice of the edentulous patients for cost reasons and most patients, while satisfied, do not replace their dentures in the recommended period. Despite the little options available in the market, some patients need teeth with different cusps heights, according to their condylar guidance inclination. The food promotes greater penetrating power into the food bolus; it has not yet been proven [4] This clinical report displays how the application of different posterior teeth cusps heights can influence the excursive movements of the patient
