Objectives: This study aimed to investigate masticatory muscle activity in patients treated with
2 modalities of implant mandibular overdenture prosthesis.
Methodology: Fourteen completely edentulous male patients were selected and four implants
were inserted for each patient. After 3 months of installation, the patients were equally divided into
two groups; group I receiving overdentures retained with ball attachments and group II receiving
telescopic retained overdentures. Muscle activity was measured at time of denture insertion, two
weeks and one month after insertion.
Results: The results revealed that muscle activity was significantly lower in telescopic retained
overdentures compared to overdentures retained with ball attachments.
Conclusion: Telescopic attachments decreased the effort exerted by the muscles compared to
ball and socket attachments.
