Introduction:
Immediate implant placement and provisionalization in the maxillary aesthetic zone necessitates meticulous treatment planning. The integration of intraoral scanning with cone beam computed tomography allows for three-dimensional prosthetic-driven planning of the implant. Additionally, it facilitates static computer-assisted implant surgery and prefabrication of a temporary restoration, enabling chairside restoration of the immediate implant. This study aimed to evaluate the clinical, aesthetic, radiographic, and patient-reported outcomes after immediate implant placement and restoration.
Materials And Methods:
In a prospective case series, 30 patients with a failing tooth in the maxillary aesthetic zone were included and received immediate implant placement with a bone graft and a prefabricated temporary restoration. The definitive restoration was placed 3 months later. The clinical, aesthetic, radiographic, and patient-reported outcomes were collected prior to implant treatment, 6 weeks after the temporary restoration, and 1 month and 1 year after the definitive restoration.
Results:
The prefabricated temporary restoration could be placed in all patients. Three cases of early implant failure were observed (implant survival rate 90%); hence, 27 patients were evaluated after 1 year. The survival and success rates were 100% for the temporary and 100% and 96%, respectively, for the definitive restorations. Plaque, bleeding on probing, and peri-implant inflammation were absent in most cases. At the 1-year follow-up, the mean (SD) Pink Esthetic Score and White Esthetic Score (scale 0-20) was 15.4 (2.5). The mean (SD) marginal bone level change between implant placement and the 1-year follow-up was -0.18 mm (0.57) on the mesial side and -0.44 mm (1.23) on the distal side. The median buccal bone thickness remained stable after immediate implant placement and grafting. The mean (SD) patient satisfaction (scale 0-10) was 9.2 (0.8) at the 1-year evaluation.
Conclusion:
The digital workflow has the potential to enable the manufacture of prefabricated temporary restorations, leading to satisfactory clinical, aesthetic, radiographic, and patient-reported outcomes after immediate placement of single-tooth implants in the aesthetic zone.
