Implant-supported overdentures using the Locator® system show good patient satisfaction and retention. However, frequent maintenance is needed due to component wear and retention loss in these dental prostheses.
Area of Science:
- Dentistry
- Prosthodontics
- Biomaterials
Background:
- Implant-supported overdentures offer a stable prosthetic rehabilitation solution.
- The Locator® attachment system is a common choice for overdenture retention.
Purpose of the Study:
- To systematically review the success rate, complications, maintenance, and patient satisfaction of implant-supported overdentures utilizing the Locator® system.
Main Methods:
- A systematic review was conducted using the PICO approach.
- Literature search performed in PubMed®, B-On®, and Cochrane® databases.
- Article selection based on relevance and scientific evidence level.
Main Results:
- Ten articles were included in the analysis, focusing on mandibular and bi-maxillary rehabilitations.
- Complications primarily involved loss of retention and replacement of the nylon male component.
- Patient satisfaction was a frequently highlighted positive outcome.
Conclusions:
- The Locator® system demonstrates good retention for implant-supported overdentures in both arches.
- High patient satisfaction suggests it's a viable option for prosthetic rehabilitation.
- The system necessitates regular maintenance due to observed complications.
