Clinical Trial Summary

To compare the use of demineralized autogenous tooth graft versus autogenous bone graft, in the jumping gap in immediate implant placement with immediate loading.


Clinical Trial Description

Immediate implant placement was introduced in 1978, using a ceramic implant made of Al2O3. Ever since then it has become one of the most successful treatment options to maintain the alveolar bone after tooth extraction, showing success rate of more than 95%. Continuous research and development of immediate implant techniques keep being introduced, stemming from the fact that immediate implant placement is a safe, predictable, and favorable solution after the loss of a tooth. A 2 mm jumping gap is recommended in the treatment guidelines proposed in an ITI Consensus Conference. This provides sufficient space to fill the bone defect between the exposed implant surface and the facial bone wall with an appropriate bone filler. A gap in these dimensions also provides a space for the formation of a blood clot which can subsequently reorganize into a provisional connective tissue matrix and support the formation of newly formed woven bone. This was demonstrated in a preclinical study in which a wider defect and bone wall dimension were associated with less crestal bone height reduction and more bone to implant contact than a narrower defect and bone wall dimension. Also, immediate placement with a dual-zone augmentation technique, and a socket seal technique utilizing a prefabricated shell made of acrylic and immediate restoration, out of occlusion showed very promising results. The addition of graft material during immediate implant placement is very common and useful in many cases. Autogenous bone graft is considered to be the gold standard graft material, which makes comparing new graft materials to it sensible. Still, tooth bone graft has been used numerous of times for socket preservation, and it shows good results. ;
