Digital Workflows for Restoring Patient-Specific Implants and Digitally Designed Subperiosteal Implants.

Area of Science:

• Dental Implantology
• Oral and Maxillofacial Surgery
• Biomaterials Engineering

Background:

• Classic subperiosteal implants (CSI) have a long history in dentistry, particularly for managing severe alveolar bone atrophy.
• Advancements in digital technology have spurred renewed interest in subperiosteal implant techniques.
• Patient-specific implants (PSI) are emerging as a modern adaptation of traditional CSI.

Purpose of the Study:

• To provide a comprehensive overview of the historical evolution of subperiosteal implants.
• To detail the treatment planning considerations for patient-specific subperiosteal implants.
• To outline the design principles and fundamental requirements for successful PSI placement and restoration.

Main Methods:

• Literature review of classic subperiosteal implant techniques and their evolution.
• Analysis of digital technologies impacting implant design and fabrication.
• Synthesis of current best practices for patient-specific implant treatment planning and surgical execution.

Main Results:

• CSI have been a valuable tool for decades, especially in cases of significant bone loss.
• Digital technologies enable highly precise, patient-specific designs for subperiosteal implants.
• Successful PSI outcomes depend on meticulous treatment planning, accurate design, and proper surgical placement.

Conclusions:

• Patient-specific implants represent a significant advancement over classic subperiosteal implants.
• The integration of digital workflows is crucial for optimizing PSI outcomes.
• Further research can refine the application of PSI for complex restorative cases.
