Brief 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.

Outcome Measures

Primary Outcomes (3)

  • 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

  • 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.

Study Arms (2)

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.

Other: Double short implant

Single short implant

Interventions

Patients receives 2 short implants to restore missing posterior teeth, loaded with splinted screw retained crowns.

Two short implants

Patients receives single short implants, loaded with single screw retained crowns.
