Both tooth-supported and implant overdentures will help prevent bone loss and offer a more stable fit and more comfortable experience by attaching to an anchor in the jaw.
With tooth-supported overdentures, the remaining teeth you have are leveraged to act as the anchors for a removable denture that attaches securely over top. The ligaments (soft tissue) around the natural tooth structure allow you to feel a more normal sensation of chewing than with traditional dentures.
With implant overdentures, dental implants are surgically placed into the maxillary (upper) and/or mandibular (lower) jawbone to provide strong and durable support. Implant-supported overdentures allow your dentist to optimize the best support for your bone structure by customizing the number and type of dental implants used, and the option of a fixed (permanent) denture instead of a removable denture.
