What can happen if excessive cantilever forces are applied to implants?

When excessive cantilever forces are applied to implants, the primary concern is the potential for implant loosening. Cantilever forces occur when an implant extends out beyond its support structure, creating a leverage effect that can place undue stress on the implant itself and the surrounding bone. This excessive force can lead to several biomechanical challenges.

Implants are designed to function within certain load limits, and surpassing these limits may compromise the osseointegration process, where the bone fuses effectively to the implant. If the cantilever load exceeds what the implant can handle, it may result in micro-movements, which can contribute to the loosening of the implant. This scenario can create increased stress on the surrounding bone and potentially lead to bone resorption, further jeopardizing the stability and success of the implant.

Maintaining the appropriate distribution of forces and minimizing excessive cantilever loads is crucial for ensuring long-term stability and function of dental implants. Understanding this concept is essential for practitioners when planning and executing dental implant placements and restorations.
