Brief summary

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.

Interventions

PROCEDUREXenograft

The jumping gap and surrounding space will be augmented and packed with Xenograft

Masking description

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.

Inclusion criteria

* Patients with non-restorable mandibular molars * Both sexes with age range from 25 years to 40 years * Good oral hygiene * Adequate alveolar bone dimensions for implant replacement * Adequate bone volume after extraction to achieve primary stability of the immediate implant * Co-operative patient

Exclusion criteria

* Patients with any systemic disease as uncontrolled diabetes or osteoporosis * Heavy smokers with smokers more than 10 cigarettes per day * Pregnancy * Patients with any signs of active infection or pus formation * Patients undergoing chemotherapy or radiotherapy, immunocompromised patients

Design outcomes

Primary

MeasureTime frameDescription
Horizontal bone thickness in millimeters6 months postoperativeTwo CBCT images will be taken, one immediately after surgery (baseline) and the other at 6 months post-surgically

Secondary

MeasureTime frameDescription
Vertical bone height in millimeters6 months postoperativeTwo CBCT images will be taken, one 2 days after surgery (baseline) and the other at 6 months post-surgically
Pain intensityOne week postoperativeThe pain will be recorded by participants at 1, 3, and 7 days after surgery using the Visual Analogue Scale (VAS), which ranges from 0 to 10. The minimum score is 0, indicating no pain, and the maximum score is 10, representing the worst possible pain. Higher scores on the VAS indicate worse outcomes in terms of pain experienced.
