Evaluation of Short Implants' Success for Teeth Replacement in Atrophic Posterior Mandibular Ridge

Not Applicable

Completed

• Conditions: Alveolar Bone Loss
• Interventions: Other: Double short implant; Other: Single short implant

• Registration Number: NCT04414709
• Lead Sponsor: Alexandria University

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.

Detailed 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.

Arm && Interventions

Group	Intervention	Description
Two short implants	Double short implant	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.
Single short implant	Single short implant	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.

Primary Outcome Measures

Name	Time	Method
Implant Stability	6 months	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.
