Objective: Complete denture occlusion is the most important factor that affect the masticatory performance and
patient satisfaction. This study evaluates the impact of the type of occlusion used in complete dentures.
Methods: Thirty edentulous patients referred for construction of new complete dentures, to Marmara University,
Faculty of Dentistry, Department of Prosthodontics were enrolled in this study. The Ethics Committee of the University
of Marmara approved the protocol. Two sets of dentures that have bilaterally balanced and lingualized occlusion
were made for each patient. Patients used both type of dentures for 6 months. A single blind study design was
used, in which the patients were not aware of exchanging the dentures. In 3 months period, the electromyographic
measurements were performed for the anterior temporalis and masseter muscles. At 6 months period, the patient
satisfaction was evaluated.
Results: Lingualized occlusion at 6 months measurements showed the highest values for anterior temporalis and
masseter muscles while chewing gum (174.5 μV-208.19 μV, respectively) and eating peanut (211,26 μV-260,29
μV, respectively). The highest values of maximum biting were also found at lingualized occlusion in 6 months
measurement for both anterior temporalis and masseter muscles (142.91 μV-187.55 μV, respectively). The mean
chewing time decreased with lingualized occlusion (18.36 s). Patients’ ratings with lingualized occlusion were higher
with respect to bilateral balanced occlusion.
Conclusion: Lingualized occlusion resulted in a greater masticatory performance and patient satisfaction.
Key words: Balanced occlusion, complete denture, electromyography, lingualized occlusion, patient satisfaction
