- 7. Patient Education Dental Implants A dental implant is an artificial tooth root. Implant restorations look and feel more like your natural teeth than other therapies. For those who have removable restorations (full or partial dentures) dental implants increase stability, function, esthetics and preserve the structural integrity of bone. www.indiandentalacademy.com © Centerpulse Dental Inc., 4937 rev 04/03

- 25. HEALING Emanating from existing bone, new bone is formed by osseo conduction directly on the implant surface following the contour of the threads. The osteogenic cells differentiate into osteoblasts. By this,always new osteogenic cells, socalled pre osteoblasts,must be recruited from stem cells and have to migrate to the front part of bone formation. www.indiandentalacademy.com
- 26. Pre osteoblasts form cytoplasmic extentions,socalled pseudopodia, which are important for both cell attachment and migration on solid surfaces. By means of pseudopodia, pre osteoblasts make use of porous structures of implant surface to migrate and become attached. www.indiandentalacademy.com
- 27. Pre osteoblasts become differentiated into osteoblasts and start the secretion of bone matrix. Subsequently, the collagenous bone matrix becomes minerallized and deposites of woven bone are formed directly on the implant surface. There by, initially a small band of woven bone follows the contour of the threads.This small band broadens and matures to lamellar bone. www.indiandentalacademy.com
