简要总结
To evaluate a novel method using a designed tenting abutment to reduce number of surgeries and the edentulous healing period is shortened. In addition, to prevent vertical and horizontal collapse of the bone graft and minimizes resorption of the bone graft during the healing the atrophic posterior mandible.
The tent pole provides excellent mechanical properties; stability & fixation, yet very poor features to preserve the integrity of the soft tissue.
Using the tenting abutment technique will help preserve the soft tissue and decrease the amount of dehiscence that might accompany the use of the tent pole.
详细描述
Augmentation of insufficient bone volume can be brought about by different methods, including, particulate and block grafting materials, guided Bone Regeneration with or without growth and differentiation factors, ridge splitting, expansion and distraction osteogenesis, either alone or in combination. These techniques may be used for horizontal/vertical ridge augmentation.
Xenograft bone has been utilized for the reconstruction of large 3-dimensional defects because it has no donor site morbidity and is of an unlimited volume in quantity.
Guided bone regeneration (GBR) describes the use of membranes to regenerate bony defects. A membrane for GBR needs to be biocompatible, cell occlusive, non-toxic, moldable and possess space-maintaining properties including stability.
- e. Explanation for choice of comparators (conventional titanium mesh): Tent pole offers superb mechanical properties for guided bone regeneration treatment in larger areas and it is regarded one of the most available covers for guided bone regeneration yet one of the cheapest.
