Implants in fresh extraction sockets: a prospective 5‐year follow‐up clinical study

Abstract Objective: The aim of this prospective study was to evaluate the 5‐year clinical outcome of the ‘immediate implants.’ Material and methods: One week after the cementation of the prosthesis, a clinical baseline examination was carried out. Clinical measurements were performed of the following: plaque, mucositis, probing pocket depth , and soft tissue position . The height of the keratinized mucosa was measured at the buccal/lingual aspects. Standardized intra‐oral radiographs were taken. The marginal level of bone to implant contact [radiographic (Rx) bone level] was measured, and Rx bone level change over time was evaluated. The clinical/radiographic measurements were repeated on a yearly basis. The subjects were enrolled in a carefully supervised oral hygiene program. Results and conclusion: It was demonstrated that ‘immediate implants’ that were loaded after 5–7 months had a high success rate. During the 5‐year interval, no implant was lost, and the mean Rx bone level at the implants was maintained or even improved. The plaque and mucositis scores were low (<20%) at baseline and at all re‐examinations. Implant sites located adjacent to the teeth showed bone gain during the initial period while sites that were facing edentulous zones lost some bone.
