Summary
The Bone into Bone (BiB) technique shows comparable horizontal bone augmentation results to guided bone regeneration (GBR) for lateral ridge augmentation. This easily reproducible BiB method offers reduced patient morbidity.
Area of Science:
- Oral surgery
- Periodontology
- Regenerative medicine
Background:
- Horizontal bone augmentation is crucial for dental implant placement.
- Traditional guided bone regeneration (GBR) involves membranes and bone graft materials.
- Alternative techniques are sought to simplify procedures and reduce patient morbidity.
Purpose of the Study:
- To compare the efficacy of the Bone into Bone (BiB) technique with porcine cortical barriers against the guided bone regeneration (GBR) technique for lateral ridge augmentation.
- To evaluate the outcomes of BiB technique in a surgical bone gap, buccal to the defect.
Main Methods:
- Retrospective case-control study involving 23 subjects (BiB technique) and 18 subjects (GBR technique).
- BiB group used porcine cortical barriers.
- GBR group used a resorbable membrane with heterologous bovine particles and autologous bone fragments.
- Radiological and histological analyses were performed 8 months postoperatively.
Main Results:
- Mean ridge width increased from 4.8 mm to 7.5 mm in the BiB group (8 months postoperatively).
- Mean ridge width increased from 3.4 mm to 7.1 mm in the GBR group (8 months postoperatively).
- Histological analysis at 8 months revealed native, mineralized bone with a lamellar pattern (30.3% ± 5.3) in the BiB group.
Conclusions:
- The Bone into Bone (BiB) technique using resorbable heterologous biomaterials is a viable alternative for horizontal bone augmentation.
- The BiB technique, without retention devices, is easily reproducible and associated with reduced patient morbidity.
- This technique offers a promising, simplified approach to lateral ridge augmentation.
