ABSTRACT: Mandibular single denture opposed by maxillary natural
dentition showed a great problem. However, mandibular
implant overdenture treatment has gained considerable recognition. Ten male patients with complete
mandibular edentulous arch and opposing arch have full natural dentition.
Patients were divided into two groups. All patients received two endosseous titanium implants. In Group I, patients were rehabilitated with conventional
implant retained overdentures. While in Group II, Patients were rehabilitated
with occlusal reactive implant overdentures. A Novel proposed biosensor was used to measure the amount of biting force on
the implant retained overdenture. Quantitative electromyographic (EMG) signals
of the masseter and anterior fibers of temporalis muscles were recorded,
filtered and directly interfaced with a computer to represent the data
graphically. The mean amplitude (μV), turn, and activity were recorded at the
baseline and after three months. The results revealed an increase in the muscle
activity in group II after three months as compared to group I. Significant
difference in bilateral biting force at the premolar-molar area was found
between group I and group II after three months. This study concluded that a
resilient implant overdenture denture could be a desirable treatment in
mandibular overdenture supported by two implants with resilient attachment and
opposing natural dentition due to its easy fabrication and durability in use
and increased muscle activity.
