Does guided bone regeneration to improve implant prosthetic outcome still a predictable surgical procedure in implant dentistry?
Bone augmentation in implant dentistry consists to look more in details about the Diagnosis and Clinical evaluation of the Implant specific site.
- Anatomy of the ridge and the amount of alveolar bone resorption to be augmented in Horizontal and vertical dimensions.
- Phenotype (Thickness and quantity) of the soft tissue.
- Quality of the adjacent teeth as Position and their Periodontium, and relationship with the Anatomical landmark.
- Choice of bone augmentation approach as One stage or two stages.
- One stage: bone augmentation with simultaneous implant placement.
- Two stages: bone augmentation first and implant placement between 4-6 months later.
- Timing of the bone augmentation:
- Immediately with tooth extraction, and implant placement.
- After soft tissue primary closure in 6-8 weeks post extraction.
- Delayed in 3-6 months post extraction or Later.
The predictability of the guided bone regeneration will depends on many factors:
- Topography of the defect: Horizontal better than Vertical, positive for Dehiscence and Fenestration.
- Space keeping of the regenerated defect while using Bone graft substitutes and Barrier Membranes.
- Selection of Bone Graft materials: Best for Autogenous, then for Allograft, Xenograft And Alloplastic.
- Barrier Membranes: better bone formation in NON RESORBABLE/Titanium reinforced, Than RESORBABLE, with fixation means.
In conclusions, the requirements for predictable bone augmentation with Autogenous or synthetic Bone graft materials with the help of barrier membranes will be focused. The choice of surgical approach will be explained upon clinical situations.
