Implant-supported restorations in prosthetics involve the placement of dental implants into the jawbone, which serves as artificial tooth roots. These implants are typically made of biocompatible materials such as titanium that can integrate with the surrounding bone through a process called osseointegration.
Once the implants are placed, prosthetic components such as abutments and crowns or dentures are attached to them, providing functional and aesthetic replacements for missing teeth. The key to preserving bone in this process lies in the biomechanical properties of implant-supported restorations.
When a natural tooth is lost, the forces exerted during chewing and biting are no longer transmitted to the underlying bone. This lack of stimulation can lead to bone resorption, where the bone gradually diminishes in volume and density.
Implant-supported restorations help counteract this bone loss by transferring the forces generated during chewing and biting directly to the jawbone. The implant acts as an artificial tooth root, anchoring the restoration and distributing the forces evenly to the surrounding bone. This stimulation mimics the natural function of a tooth, promoting bone maintenance and preventing its degradation.
By preserving the bone, implant-supported prosthetics offer long-term stability, better aesthetics, and improved functionality compared to traditional removable dentures or bridges. Additionally, maintaining the integrity of the jawbone supports facial structure and prevents the sunken appearance often associated with significant bone loss in the jaw.
Therefore, the use of implant-supported restorations and the promotion of osseointegration are crucial aspects of prosthetics that contribute to the preservation of bone in the oral cavity.
