NICOLAS-SILVENTE, A Isabel et al. The use of immediate placement of definitive transmucosal abutments. Av Odontoestomatol [online]. 2020, vol.36, n.2, pp.99-106.  Epub 05-Dez-2022. ISSN 2340-3152.  https://dx.doi.org/10.4321/s0213-12852020000200006.

The use of transmucosal healing abutments before the placement of the definitive prosthetic abutment is a technique that has been developed for many years in classical implantology. Repeated disconnection and connection of theses abutments result in a negative bone response that manifests as bone loss at the marginal ridge level, accompanied by apical soft tissue migration. This article aims to review the current status in the scientific literature of the use of the definitive transepithelial abutments with immediate placement on the day of implant insertion and maintenance of the biological seal, minimizing peri-implant bone loss and adequately remodeling the adjacent soft tissues, compared to the traditional protocol of the use of abutments that are disconnected on multiple occasions producing peri-implant bone loss. Scientific evidence suggests that the best biological, aesthetic, and functional results are achieved with the use of the definitive abutment placed immediately after implant insertion, especially in yuxtacrestal implants and post-extraction implants.
