Effect of Albumin Platelet-Rich Fibrin or Leucocyte- Platelet-Rich Fibrin on Immediate Implant

Clinical and Radiographic Evaluation of Xenograft With Albumin Platelet-Rich Fibrin or Leucocyte- Platelet-Rich Fibrin on Immediate Implant Placement in Mandibular Molar Extraction Sites: Randomized Clinical Trial.

The objective of this study will be to compare between Immediate Implant grafted with xenograft and Alb-PRF gel versus xenograft with L-PRF.

The objective of this study will be to compare between xenograft with Alb-PRF gel and xenograft with L-PRF ( L-PRF Block ) in the aspects of :

• Peri-implant vertical defect depth.
• Crestal bone level.
• Bucco-lingual bone width.
• Keratinized tissue width

1. Inclusion criteria

   • The presence of non-restorable mandibular molar.
   • Patient 18-45 years old
   • Intact buccal and lingual walls
   • Good oral hygiene.
   • Prescence of sufficient restorative space.
   • Jumping gap more than 2 mm.

2. Exclusion criteria

   • Proximity of anatomical structures
   • Acute localized infection (suppuration at the surgical field)
   • Patients on chemotherapy or radiotherapy.
   • Patients who have systemic disorders (diseases) {diabetes mellitus, autoimmune disease, …etc},
   • Pregnant patients.
   • Smoking and Alcohols.
   • Presence of periapical pathology affecting the neighboring teeth.
