Summary
Guided bone regeneration (GBR) using either collagen membranes or titanium mesh effectively augments horizontally deficient maxillary alveolar ridges. Both methods showed significant bone width increase, with collagen membranes offering a less technique-sensitive option.
Area of Science:
- Oral and Maxillofacial Surgery
- Periodontology
- Regenerative Dentistry
Background:
- Alveolar ridge reconstruction is crucial for dental implant success.
- Guided bone regeneration (GBR) is a key technique for horizontal bone deficiency.
- The optimal barrier material for GBR remains a subject of debate.
Purpose of the Study:
- To compare bone quantity and quality gained via GBR using collagen membranes versus titanium mesh.
- Both barrier types were used with a 1:1 mixture of autogenous and anorganic bovine bone mineral (ABBM).
- The study focused on horizontally deficient maxillary alveolar ridges.
Main Methods:
- A comparative study involving 20 patients undergoing GBR for horizontal maxillary ridge augmentation.
- Ten patients received GBR with a native collagen membrane and a bone graft mixture.
- Ten patients received GBR with a titanium mesh and the same bone graft mixture.
Main Results:
- Both techniques significantly increased alveolar bone width (4.0 mm for collagen, 3.7 mm for titanium mesh).
- Bone area percentage was comparable (~28%) between the groups.
- Titanium mesh showed higher rates of mesh exposure (4/10 cases) and potential complications compared to collagen membranes.
Conclusions:
- GBR with both collagen membranes and titanium mesh is effective for horizontal maxillary ridge augmentation.
- Collagen membranes present a less technique-sensitive alternative to titanium mesh.
- Complications associated with titanium mesh, such as dehiscence and removal difficulties, may limit its application.
