Abstract
SUMMARY
The aim of this study was to compare the effect of degree of palatal
coverage on the occlusal forces exerted by implant retained maxillary
overdenture using T-Scan.
Sixteen male patients were selected from the out-patient clinic of
Prosthodontic Department, Faculty of Dentistry Shams University according
certain criteria
Patients were randomly divided into two equal groups:
Patients of group A received implant supported maxillary
overdentures with complete palatal coverage opposed by implant supported
mandibular overdenture, while patients of group B received implant
supported maxillary overdentures with partial palatal coverage opposed by
implant supported mandibular overdenture.
T-scan device was used to record and analyze the biting force of the
denture. T-scan record at the first molar region was taken three times for each
patient in the two groups, first at the time of loading then after three weeks
and last record was taken after three months of loading.
Data at the different follow up periods for the two groups was
collected, tabulated and statistically analyzed.
Within the limitation of this study, the results revealed that no
statistically significant difference was found between the two groups
throughout the follow up period
The results also revealed no statistically significant difference
between occlusal forces within the same group at different follow up period.
