Clinical Trial Summary

aim Evaluation of the amount of bone gain following Ridge augmentation using tunneling technique in atrophic posterior mandibular ridges using anorganic bovine bone derived mineral mixed with particulated autogenous bone chips with collagen membrane

Description:

Bone grafting before implant placement has become a routine procedure over the last 20 years. A 5-year survival rate of up to98.3% for implants placed in grafted bone has been reported.

Autologous bone grafts are considered the gold standard.However, the success rate of the grafting procedure may beinfluenced by various risk factors.

A particular challenge isposed by an extensive graft of the alveolar ridge, with relativelyhigh complication rates of up to 20% being reported, mostcommonly dehiscence. More serious complications such asdehiscence or mobilization of the graft were observed in one third of smokers compared to a complication rate of only 7.7%for non-smokers. Complications such as flap necroses, dehiscenceand resorption are frequently soft-tissue complications.

A tension-free wound closure is a key factor in the successof bone grafts. Periosteal incisions are a common techniquefor flap extension. However, too many relief incisions in the periosteum may also result in an excessively thin or stretched wound flap.

This type of soft-tissue management may result in perforation or flap necrosis above the bone graft.

In 1987 Härle reported on a tunneling access in connectionwith a technique for preprosthetic jaw ridge grafting in the mandibular side-tooth region with bone replacement materials.

In the clinical experience of the authors the use of a tunneling technique for preparation without a crestal incision can present an alternative with autologous bone grafts to conventional surgical procedures with a trapezoid flap design.
