Immediate Postextraction Single-Tooth Implants and Provisional Crowns in the Esthetic Area: 2-year Results of a Cohort Prospective Multicenter Study- Patient-Centered Outcomes.

Purpose: A prospective cohort multicenter study was undertaken to identify risk factors for implant survival, complications, and patient-centered outcomes following single-tooth immediate implant placement and loading in esthetic areas.

Materials And Methods: Consecutive immediate implants placed in incisors, canines, and premolar sites were included. Variables recorded as possible risk factors included smoking habit, systemic conditions or therapies, previous assumption of bisphosphonates, inability to take amoxicillin, untreated periodontitis, thin periodontium, parafunctional habits, suppuration, bone dehiscences, and buccal bone fracture during implant insertion.

Distraction osteogenesis for implant site development using a novel orthodontic device: a case report.

The case report describes the distraction osteogenesis of a small bone fragment supporting a maxillary central incisor that had become ankylosed and infraoccluded after trauma. After initial orthodontic treatment, surgery was performed, entailing a trapezoidal osteotomy with minimal periosteal elevation through a horizontal incision. On this occasion, a device was applied, anchored to the tooth, and activated by a micrometer screw.
