Clinical Trial Summary

The aim of this study was to evaluate clinically and radiographically the splinted short implants' and single short implants' stability and bone condition before and after loading, in atrophic posterior mandibular alveolar ridges.

Description:

A prospective study was conducted on 16 Patients with missing posterior molars. Group A: 8 patients had 2 short implants placed in atrophic posterior mandibular alveolar ridge. Group B: 8 patients had a single short implant placed in atrophic posterior mandibular alveolar ridge.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Implant Stability	Implant stability was measured using Implant Stability Quotient (ISQ), a scale from 1 to 100. The ISQ scale has a non-linear correlation to micro-mobility. High stability means >70 ISQ, between 60-69 is medium stability and < 60 ISQ is considered as low stability.	Immediately after the operation
