Subperiosteal implant has come to the fore again with cur- rent technological developments. It offers an alternative therapeutic option in the rehabilitation of advanced atrophic jaws. It is a minimally invasive approach compared to com- plex regenerative treatments, and it also provides immediate functional and aesthetic improvements [1]. However, some complications have been observed regarding custom-made subperiosteal implants, as in every surgical procedure [2]. Among the most common complications are mucosal reces- sion and exposure of the implant skeleton. Soft tissue phe- notype, amount of keratinized gingiva, and alveolar bone morphology are parameters that need to be evaluated before the operation and adjusted with additional surgical interven- tions when necessary. The literature reports that the knife- edge alveolar crest and sharp bone edges cause late-term biological complications [3].
