The present disclosure features adhesive compositions and methods of use thereof related to the medical, veterinary, and dental fields.

A dental implant method comprises securing a denture to a denture receiving component installed to a wearer's dental arch, using normal hand force. The denture receiving component includes a first interlocking platform configured to mate lock with a second interlocking platform in the denture to secure the denture. The second interlocking platform is further configured to detach from the first interlocking platform to release the denture using normal hand force. The denture can be fully held in place by the denture receiving component and does not require gum tissue coverage or extraneous elements for support.

Disclosed are example embodiments of methods and systems for improving teeth appearance and repositioning of the teeth. One of the systems is an appliance that includes: an outer shell with simulated teeth that approximate a final teeth arrangement; and inner cavities configured to receive a patient's teeth and to incrementally reposition the teeth toward the final teeth arrangement.
