Implant-Retained Overdentures Using an Attachment with True-Alignment Correction: A Case Series.
The International Journal of Prosthodontics
|October 31, 2019
Summary
This study showcases a novel implant attachment (CM LOC FLEX) that corrects angular discrepancies for implant-retained overdentures (IODs). It successfully enabled metal-free IOD fabrication using PEKK frameworks in complex cases.
Area of Science:
- Dental Implantology
- Prosthodontics
- Biomaterials Engineering
Background:
- Implant parallelism is crucial for implant-retained overdentures (IODs), particularly with unsplinted attachments.
- Compensating for inter-implant angular discrepancies often presents challenges in achieving true parallelism.
Observation:
- A novel CM LOC FLEX attachment offers true alignment correction for non-parallel implants.
- This attachment was successfully used in two cases: a two-implant mandibular IOD and a four-implant maxillary IOD.
- A novel polyetherketoneketone (PEKK) framework was utilized for metal-free IOD fabrication.
Findings:
- The CM LOC FLEX attachment effectively corrects inter-implant angular discrepancies, achieving parallelism.
- The PEKK framework provided a lightweight, strong, and aesthetic alternative to traditional metal frameworks.
- Both novel solutions were successfully applied in complex clinical scenarios with compromised implant parallelism.
Implications:
- The CM LOC FLEX attachment may offer significant advantages in managing non-parallel implants in IOD cases.
- PEKK frameworks present a promising option for fabricating esthetic, metal-free IODs.
- Further clinical studies are required to validate the long-term performance and maintenance of these novel approaches.
