Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Twenty recruited patients indicated for immediate implant placement in mandibular molar sites are divided into two groups, with each group containing ten patients. One group assigned for placement of xenograft after molar extraction and immediate implant placement, while the other group received allograft as space-filling material.

Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Participants
This trial is considered a randomized single blind clinical trial due to the following:

* The participants will be blinded to the technique that will be used during the surgical procedure.
* The operator will not be blinded for both techniques during the surgical procedure as the two techniques are different.
* The outcome assessor cannot be blinded.
