What is the minimum occlusal distance needed for implant retained overdentures with individual attachments?

The minimum occlusal distance needed for implant retained overdentures with individual attachments is critical to ensure adequate functioning and support of the prosthesis. A distance of 10-12 mm is necessary because it provides sufficient space for the components of the implant system, including the abutment and attachment mechanisms. This distance allows for proper alignment and prevents mechanical complications that can arise from insufficient space, such as screw fracture or loosening.

Furthermore, a minimum of 10-12 mm ensures adequate vertical space for the denture base and contributes to the overall stability and retention of the overdenture. It supports proper esthetic outcomes, as it allows the clinician to create an appropriate contour for the soft tissue around the implant, which is important for both function and aesthetics.

When considering other ranges suggested, they may not provide enough clearance for the diverse components necessary for effective attachment systems, potentially leading to complications that can affect the longevity and functionality of the overdenture. Overall, the 10-12 mm range is a clinically accepted minimum to ensure that all necessary components fit comfortably while maintaining oral functionality.
