Horizontal bone augmentation by means of guided bone regeneration

Area of Science:

• Dental Implantology
• Periodontology
• Biomaterials Science

Background:

• Bone augmentation procedures enable dental implant placement in areas with insufficient jaw bone volume.
• Guided bone regeneration (GBR) is the most documented method for augmenting localized alveolar defects, expanding implant indications.
• While GBR shows success in bone regeneration and implant placement, its long-term impact on implant survival and augmented bone stability is not fully understood.

Purpose of the Study:

• To present the scientific basis and accepted clinical procedures for guided bone regeneration.
• To classify bone defects to aid in selecting bone augmentation strategies.
• To provide an outlook on current research and future directions in bone augmentation for dental implants.

Main Methods:

• Review of existing scientific literature on guided bone regeneration techniques and materials.
• Presentation of a classification system for alveolar bone defects.
• Discussion of recent advancements and future research trends in bone augmentation.

Main Results:

• Guided bone regeneration is a well-established technique for regenerating bone at implant sites with insufficient volume.
• Evidence supports the long-term success of implants placed with or after GBR procedures.
• Gaps in knowledge exist regarding the long-term influence of GBR on implant survival and augmented bone stability.

Conclusions:

• Guided bone regeneration is a crucial procedure for modern dental implantology, allowing treatment in complex cases.
• Further clinical studies are needed to validate new materials and techniques and to fully understand long-term outcomes.
• A standardized classification of bone defects can improve treatment planning and decision-making for bone augmentation.
