| Abstract | ||
| Purpose: The study aimed to compare progression of masticatory efficiency associated with mandibular bar-supported overdentures either retained by immediately or delayed loaded two implants. Material and Methods: A total 12 completely edentulous patients with persistent complaints from their complete mandibular dentures were chosen. Each participant received two dental implants of (3.8 mm x 12 mm) bilaterally using computer-guided flapless surgery. The participants were grouped according to the bar attachment design into two equal groups. Group SB: six participants received mandibular overdenture supported by immediately loaded two implants connected with prefabricated SFI-Bar system. Group CB: six participants received mandibular overdentures supported by delayed loaded two implants splinted with conventional cast Co-Cr bar attachment. Glucose extraction method was performed to objectively measure the masticatory efficiency for each patient at different time points including; including; one week after implant-bar connections connections (T0), six months after implant-bar connections (T6), and 12 months after implant-bar connections (T12). Results: There were statistically significant difference of masticatory efficiency between the (SB) and, (CB) (P=.004 and P=.001 respectively). Starting from T0, the findings showed highly statistical significance (P=0.000) in improving the masticatory efficiency at (T6) and (T12) respectively. Conclusion Regardless the limitations of this clinical study, it can be conclude that restoring edentulous patient with mandibular overdenture assisted with bar improves the masticatory efficiency with a noticeable statistical improvement of masticatory efficiency for immediate versus delayed loading protocol. | ||
