Comparison Between PEEK With Platelet-rich Fibrin and PEEK Alone in Maxillary Sinus Augmentation

Histomorphometric and clinical analysis of the bone formed after 6 months after the maxillary sinus elevation using PEEK in the 2 groups : the study group (PEEK with platelet rich fibrin) and the control group (PEEK alone ) .

Inclusion criteria

• Patient not complain from maxillary sinusitis
• Patient with good oral hygiene.
• Both males as well as females without any active periodontal disease.
• The edentulous ridges are covered with optimal thickness of mucoperiosteum with no signs of inflammation, ulceration or scar tissue.
• Remaining natural teeth have good periodontal tissue support and occlusion showed sufficient inter arch space for future prosthesis.

Exclusion criteria

• • General contraindications to implant surgery.

• Untreated gingivitis, periodontitis.
• Subjected to irradiation in the head and neck area less than 1 year before implantation.
• Untreated periodontitis.
• Pregnant or nursing.
