Beyond biological and functional results, achieving an optimal aesthetic outcome can be a key measure of success for implant placement. This study aimed to evaluate whether the use of a provisional implant-supported crown would lead to better results in the aesthetic zone.
Fixed implant-supported provisional crowns are often used to customise emergence profiles and the surrounding peri-implant soft tissue. To determine whether this procedure has significant aesthetic benefits, researchers examined 20 patients, each requiring a single implant in the aesthetic zone.
The patients were split into two groups: one underwent a provisional phase with soft-tissue conditioning using the dynamic compression technique, and the other group did not. All placements followed an early implant protocol and were placed with simultaneous guided bone regeneration by the same practitioner.
Follow-ups took place at 3, 12 and 36 months. Clinical and radiographic parameters were assessed and an independent clinician carried out aesthetic assessments. 100% of the implants survived with one patient excluded from the study due to tooth loss. The mean Pink and White Esthetic Scores were both higher for the group with provisional loading.
Based on these results the authors conclude that a provisional phase with soft-tissue conditioning can improve aesthetic results. The authors also noted that the provisional phase does not lead to an increase in bone loss.
This study was presented as an e-poster at the 2018 EAO Congress.
