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.
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Two short implants | Experimental | DENTIUM superline implant fixture is characterized by sandblasted with large grits and acid etched surface treatment (S.L.A). SLA surface allows good bone-implant contact with good clinical performance, maintaining crestal bone margin. Short Implants of 7.0 mm length and 4.5 mm diameter are to be used. The Short Implants are characterized by 1.5mm supra-bony smooth collar, and 5.5mm infra-bony surface treated double threaded titanium. |

| Measure | Description | Time Frame |
|---|---|---|
| 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 |
