Evaluation Of Osseointegration of Immediately Placed And Loaded Dental Implants With Nanocrystalline Hydroxyappatite Particles In The Esthetic Zone (A Randomized Controlled Clinical Trial)

Immediate implant placement as a single surgical procedure has shown many advantages. Ideal implant positioning is an important advantage, socket bone preservation, and also decreasing treatment time. Several studies have reported a decreased amount of bone loss when using immediate implants directly after tooth extraction. Adequate peri-implant bone support is needed for successful immediate and long-term implant stability. Many procedures have been suggested to increase alveolar bone height and width. Xenografts have proven to be one of the most successful but also widely used grafting materials these days as they proved to be a good substitute for autogenous bone grafts. This success is due to their osteoconductive properties, and their density which shows great stability to the implant as they also supply all the needed minerals for bone formation. An example of one of the osteoinductive biomaterials is the NanoBone® (Nanocrystalline hydroxyapatite particles), which is a granular material composed of nanocrystalline hydroxyapatite mixed in silica gel matrix showing a great advantage of the nanostructural bio-materials. This bone substitute material shows many advantages as it proved to be safer, faster bone formation, complete bone remodeling, and very high performance through the nanostructure. The aim of the present study is to evaluate the osseointegration of NanoBone® (Nanocrystalline hydroxyapatite particles) around immediately placed and loaded dental implants in the esthetic zone by measuring Implant stability and Marginal bone loss.
