No full textSingle-tooth implant restoration in esthetic zone with immediate provisionalization: a clinical report.
No full textObjectives: This clinical report describes a single-tooth implant restoration in a fresh extraction socket in the anterior maxilla, with immediate provisionalization and CAD-CAM zirconia final prosthesis.
Methods and Materials: Due to a traumatic injury, an esthetically concerned 40 year-old female patient was treated with an atraumatic extraction of a maxillary central incisor, which was immediately substituted with a single implant. Immediate provisionalization was performed using a screw-retained resin crown. Two months after surgery, the patient was fitted with a final all-ceramic single crown cemented on a CAD-CAM customized zirconia abutment. Results: Healing was predictable, with the implant neither showing mobility nor presenting pain. The zirconia crown was undamaged. The patient was pleased with treatment time and esthetic result.
Discussion: Implant treatment with immediate provisionalization offers several advantages: optimal esthetics is achievable as bone and soft tissue architecture is maintained; patients are provided with a fixed temporary restoration at the time of surgery; treatment time is shortened, as second stage surgery is eliminated. Furthermore, the fresh extraction socket is a metabolically active region with good potential for bone repair and successful implant placement.
Conclusions: Optimal mechanical performances and excellent esthetics were achieved in the anterior sites by means of a CAD-CAM zirconia customized abutment and crown.
Clinical Significance: In cases where clinical conditions are favourable to the placement of an implant into a fresh post-extraction socket, such a treatment modality offers several advantages over a conventional approach

Marginal masticatory mucosa dimensional changes in immediate post-extractive implants: a 2 year prospective cohort study
No full textThe present two-year prospective cohort study was undertaken to evaluate marginal masticatory mucosa dimensional changes around immediate post-extractive implants positioned transgingivally with a non-submerged healing screw. Material and methods: Twenty-one immediate post-extractive implants from 21 patients were enrolled, peri-implant gap was filled with bovine bone mineral, and soft tissue was allowed to heal around a non-submerged healing screw. Post-extractive socket dimension was recorded. Intraoperative (T0) vertical distances: bone margin level (BML) from the bone margin to the implant platform and mucosal margin height (MMH) from marginal mucosa to implant platform were taken; MMH measurement was repeated 4 months later (T4). Horizontal mucosal level (HML): from customized stent to marginal mucosa at 0, 4, 12, and 24 months postoperatively (T0, T4, T12, T24) and vertical mucosal level (VML): from the stent to marginal mucosa at T4, T12, T24 were registered. Results: One implant failed at 3 weeks; in the remaining 20 cases the MMH, coronally positioned with respect to the BML ≅2 mm at T0, showed a statistically significant vertical contraction of the mucosa at T4. Other vertical mucosal measurements (VML) did not show further changes over time. HML measures showed a, statistically significant, shrinkage of the mucosa on the transverse plane between T0/T12 and T0/T24 and between T4/T12 and T4/T24. Conclusions: Immediate post-extractive implant inserted transgingivally with a non-submerged healing screw and internal peri-implant gap filled with bovine bone mineral may favor an early and stable peri-implant soft tissue healing over 2 years
