Background: Immediate implant placement followed by an immediate restoration has proven tobe a viable technique in the anterior maxillary region.Purpose: This prospective study evaluated the mid-long term (2-5 years) tissue changes aroundimmediately placed and restored implants in the anterior maxilla using flapless surgery and simulta-neous hard tissue augmentation.Materials and methods: Thirty AstraTech implants were immediately placed in 30 patients, fol-lowed by the delivery of an immediate provisional restoration on the same day. All participating30 patients underwent the same treatment strategy that involved flapless ...

All participating30 patients underwent the same treatment strategy that involved flapless removal of a failing max-illary anterior tooth, immediate implant placement, simultaneous augmentation with adeproteinized particulate xenograft, followed by the connection of a screw-retained provisionalrestoration. Radiographs and photographs were used to measure hard and soft tissue changes.Aesthetic evaluation was performed using the Pink Esthetic Score (PES).Results: All implants remained osseointegrated during the follow up period of 2-5 years (mean47 6 15 months). Twelve of the thirty patients completed the 5 year follow up. Radiographic eval-uation revealed average gains in bone levels of 0.18 and 0.34 mm mesially and distally,respectively. Soft tissue evaluation showed a mean tissue loss of 0.05 6 0.64 mm and 0.16 60.63 mm at the mesial and distal papillae, respectively, while mid-facial mucosal recession was0.29 6 0.74 mm. A significant improvement in the Pink Esthetic Scores was seen at the finalfollow-up (mean PES 11.50), as compared to the baseline (mean PES 10.27) (P 5 .001).Conclusions: In addition to a favorable implant success rate and peri-implant bony response, thesoft tissue levels and overall aesthetics around single immediately placed and restored implantscan also be maintained in the mid-long term.
