Abstract

Aim: This study was carried out to evaluate clinically and radiographically using
of nanocrystalline hydroxyapatite (NcHA) and platelet-rich fibrin (PRF) as a grafting
materials around the implant after narrow alveolar ridge splitting and expansion by
piezoelectric surgery. Subjects and methods: twenty systemically healthy patients with
partial edentulous narrow maxillary alveolar ridges were selected from those attending
at the Out-Patient Clinic, Oral Medicine and Periodontology Department, Faculty of
Dental Medicine, Al-Azhar University, Assiut Branch. Then they divided randomly into
the following equal groups. First Group, ten patients with partial edentulous narrow
maxillary anterior alveolar ridges, treated by piezoelectric ridge splitting and expansion
with simultaneous implant placement into their ridges. Second Group, ten patients with
partial edentulous narrow maxillary anterior alveolar ridges treated by piezoelectric
ridge splitting and expansion with simultaneous implant placement into their ridges;
combined with application of nanocrystallin hydroxyapatite bone graft mixed with
platelet rich fibrin (PRF). Patients were evaluated clinically to assess probing depth
and implant stability quotient, and radiographically to assess the alveolar ridge width,
marginal bone loss, and bone density measurement parameters at baseline, 6, 9, and
12 months. Results: Among the studded groups, there is a high statistically significant
difference between the clinical and radiographic measurements. Conclusion: Usage
of combination of nanocrystallin hydroxyapatite bone graft and platelet rich fibrin
as a grafting materials around the implant after narrow alveolar ridge splitting and
expansion by piezoelectric surgery appeared significantly superior to immediate
implant placement alone
