Tian J, et al. - In this prospective cohort study involving 30 patients, researchers quantitatively evaluated the time-dependent contour alterations of labial soft tissue after single immediate implants and immediate provisionalization (IIPP) in maxillary incisors through intraoral scanning. According to the findings, the labial soft tissue contour exhibited a continuous alteration resulting in a mean change in thickness of 0.62 mm that occurred mainly in the first three months and tended to be relatively stable after six months during the 1-year observation following single IIPP treatment in maxillary incisors. On the other hand, the crescent-like shape, width, height, and thickest point position of the alteration volume remained stable after three months. There was no advanced mid-facial recession in this analysis.
