Summary
Recent research shows a shift from nonresorbable to resorbable bone substitutes in preprosthetic surgery. These biodegradable materials, often combined with autogenous bone, show promise for bone regeneration and alveolar bone maintenance.
Area of Science:
- Oral surgery and regenerative medicine.
- Biomaterials science and tissue engineering.
Background:
- Decreased use of nonresorbable hydroxylapatite implants in preprosthetic surgery.
- Increased application of resorbable (biodegradable) bone substitutes like porous bone mineral.
Purpose of the Study:
- To review the evolving trends in bone grafting materials and techniques for preprosthetic surgery.
- To highlight the growing importance of biodegradable materials and bone induction substances.
Main Methods:
- Literature review focusing on studies from the past year.
- Analysis of the application of various bone graft materials, including composite grafts and bone induction substances.
- Examination of techniques involving intraosseous titanium implants with graft materials and membranes.
Main Results:
- A notable shift towards resorbable bone substitutes over nonresorbable hydroxylapatite.
- Successful long-range studies of composite grafts using biodegradable materials with autogenous bone.
- Emphasis on bone induction substances and their clinical applications.
Conclusions:
- Biodegradable bone substitutes are increasingly favored in preprosthetic surgery.
- Future applications may involve bone inductive techniques with both degradable and non-degradable carriers, autogenous bone, and microporous membranes for enhanced bone regeneration and alveolar bone maintenance.
