Evaluation of the Efficacy of Allograft Versus Tenting Technique in Open Sinus Lifting With Immediate Implant Placement

Not Applicable

Not yet recruiting

• Conditions: Implant Complication; Sinus; Dental; Surgery-Complications
• Interventions: Procedure: Sinus lifting with allograft; Other: Sinus lifting without graft

• Registration Number: NCT06254378
• Lead Sponsor: Cairo University

Brief Summary

Implant placement in deficient posterior maxilla is a challenging clinical situation that necessitates appropriate treatment options to restore this area.

-Aim of the study: To compare allograft vs tenting technique in terms of implant stability and bone height.

Detailed Description

Rationale for carrying out the trial:

The research population will be divided into two groups. Group1 will be treated by allograft with immediate implant technique, Group2 will be treated by tenting technique with immediate implant technique. Allograft has been effective in augmenting bone growth and has been proven to be a vital asset in sinus lifting.

Arm && Interventions

Group	Intervention	Description
Sinus lifting with graft (intervention)	Sinus lifting with allograft	Patients will receive sinus lifting with immediate implant and allograft placement.
Sinus lifting without graft (control )	Sinus lifting without graft	Patients will receive sinus lifting with immediate implant placement without graft placement.

Primary Outcome Measures

Name	Time	Method
Implant stability	During the implant placement procedure and after 6 months	implant stability quotient(ISQ) is the evaluation unit set to determine the correct isq\<60:low stability isq 60-65 : medium stability isq \>70: high stability stability of the implant, this module by means of a resonance frequency analysis (rfa) applied to the bone manages to measure stability on an isq scale from 1 to 100 (khz):

Secondary Outcome Measures

Name	Time	Method
Bone hight	Before surgery and after 6 months	Newly formed bone length will be measured on cone beam ct by millimeter
