Will there be a difference in Pink Esthetic score and soft tissue changes around immediate implants in maxillary esthetic zone following grafting the jumping gap with partially demineralized dentin matrix compared with xenograft?

This study aims to evaluate the soft tissue changes as well as hard tissue changes around immediate implants in maxillary esthetic zone following grafting the jumping gap with partially demineralized dentin matrix in comparison to xenograft.

Because xenogeneic bone is so readily available in substantial quantities, it has been the subject of notable research. However, because they contain organic material from a foreign species, xenogeneic bones are inherently very antigenic.

According to experimental results, PDDM encourages bone regeneration in a manner like autogenous bone. Both cortical bone and autogenous tooth grafts share similar physical and chemical characteristics, including optimal biodegradability, not requiring a separate surgery to harvest the graft and space maintenance capabilities. PDDM is a valuable comparator to autogenous bone in ARP and around dental implants in guided bone regeneration procedures

Inclusion Criteria:

• Patients above 18 years of age; with non-restorable teeth requiring replacement with immediate implants in the maxillary esthetic zone.
• Absence of active infection at the surgical site.
• Adequate primary stability following immediate implant placement.
• Intact socket walls following the extraction.
• Class I dental socket based on a preoperative CBCT scan
• Buccal plate thickness more than 1 mm and thick biotype.
• Compliant patients who will sign an informed consent and agree to the follow up period.

Exclusion criteria

• Poor oral hygiene or the lack of regular maintenance.
• Individuals with compromised immune system or debilitating systemic disease.
• The presence of parafunctional habits (bruxism or clenching).
• External root resorption.

baseline data and follow up measurements will be shared while keeping patients' identity protected.

The two groups will be equally prepared for both surgical procedures. Then the decision of which group will receive (PDDM), and which will receive xenograft will be taken according to the randomized numbers placed in opaque sealed envelopes. The number will be picked by the supervisor.
