Protocol for Bone Augmentation with Simultaneous Early Implant Placement: A Retrospective Multicenter Clinical Study.

Area of Science:

• Dentistry
• Oral Surgery
• Regenerative Medicine

Background:

• Alveolar bone defects pose challenges for dental implant placement.
• Simultaneous bone augmentation with early implant placement requires optimized protocols.

Purpose of the Study:

• To introduce and evaluate a novel protocol for alveolar bone regeneration concurrent with early dental implant placement.
• To assess the long-term efficacy and survival rates of this standardized approach.

Main Methods:

• A 10-year study involving 497 patients undergoing extraction, early implant placement, and bone augmentation.
• Utilized in situ hardening, fully resorbable alloplastic grafting materials (β-tricalcium phosphate and calcium sulfate).
• Protocol: atraumatic extraction, implant placement (4 weeks post-extraction), bone augmentation, and implant loading (12 weeks post-placement).

Main Results:

• 601 postextraction sites were treated using the novel protocol.
• Achieved an overall implant survival rate of 99.0% (6 implant failures out of 601).
• Mean follow-up period of 4 years, ranging from 6 months to 10 years.

Conclusions:

• The standardized protocol demonstrates successful long-term functional outcomes for alveolar bone regeneration and implant rehabilitation.
• This approach, involving early implant placement with resorbable alloplastic materials and timely loading, offers advantages over traditional methods.
