Redefining the Restorative Interface in Implant Dentistry: Intermediate Multi-Unit Abutments for Enhanced...

Area of Science:

• Dentistry
• Implantology
• Prosthodontics

Background:

• Optimal implant-supported prostheses rely on managing anatomic, phenotypic, surgical, and prosthetic factors.
• Effective restorative interface management is crucial for esthetics and long-term peri-implant tissue health, especially in the anterior maxilla.

Purpose of the Study:

• To present a workflow using intermediate multi-unit abutments on bone-level implants for tooth replacement.
• To detail digital planning, surgical protocols, and prosthetic strategies for immediate and delayed implant placement.

Main Methods:

• Employing intermediate multi-unit abutments on bone-level implants.
• Integrating digital planning, surgical protocols, and prosthetic strategies.
• Applying the technique in both immediate and delayed implant placement scenarios.

Main Results:

• Intermediate abutments can aid ridge preservation and provisional restoration in immediate implant placement.
• They may promote bone preservation between adjacent implants in delayed placement, reducing remodeling.
• This strategy supports stable marginal bone levels and long-term peri-implant tissue health and esthetics.

Conclusions:

• Intermediate multi-unit abutments offer a versatile approach for predictable esthetic and functional outcomes in implant dentistry.
• This method enhances peri-implant tissue stability and bone preservation, particularly in the anterior maxilla.
• It can also compensate for suboptimal implant positioning, improving overall treatment success.
