Abstract

Objectives: This study intended to investigate masticatory muscle activity in patients treated with two different designs of lingualized occlusal schemes in implant mandibular overdenture prosthesis.

Methodology: Twenty completely edentulous male patients were selected and two implants
were inserted for each patient. After 3 months of installation, the patients were equally divided into two groups; group I: patients were received complete denture with conventional lingualized (LO) concept and group II: patients were received complete denture with Gerber lingualized occlusion(GC). Muscle activity was measured after one week of denture insertion, one month and 3 months after overdenture insertion.

Results: The results revealed that muscle activity was significantly higher in Gerber concept than the conventional lingualized concept along the whole follow up periods with both hard and soft food and both muscles (masseter and temporalis)

Conclusion: Gerber lingualized concept was found to exert more freedom of muscles activity compared to conventional lingualized concept .
