Summary
Modern patient-specific subperiosteal implants (SPIs) offer a stable solution for retaining prostheses, even with limited bone. This case report highlights their use in securing a surgical obturator without extra wiring.
Area of Science:
- Dental Implantology
- Prosthodontics
- Biomaterials Engineering
Background:
- Limited alveolar bone presents challenges for traditional endosteal implants.
- Subperiosteal implants (SPIs) offer an alternative for prosthesis retention in such cases.
- Digital technology has improved the design and fit of modern SPIs.
Purpose of the Study:
- To report the use of a patient-specific subperiosteal implant (SPI) for retaining a surgical obturator.
- To demonstrate an alternative application of SPIs beyond fixed restorations.
- To evaluate the stability and adaptation of a custom SPI in a clinical setting.
Main Methods:
- A modern, patient-specific subperiosteal implant (SPI) was designed and fabricated using digital technology.
- The SPI was surgically placed.
- The SPI was utilized to retain a surgical obturator.
Main Results:
- The custom SPI provided excellent adaptation and stability for the surgical obturator.
- No additional interdental or interosseous wiring was required.
- The SPI facilitated secure retention of the obturator.
Conclusions:
- Patient-specific subperiosteal implants (SPIs) are a viable option for retaining surgical obturators.
- Advanced digital manufacturing enhances the precision and stability of SPIs.
- SPIs offer versatile applications in complex dental reconstructions.
