Purpose: Simplified and predictable immediate single-tooth replacement therapy can be optimised by leveraging recent advances in digital workflows that combine static surgical guidance and customised prosthesis design and fabrication. The present case report illustrates a novel approach to successfully executing immediate single-tooth replacement therapy via static computer-aided immediate implant placement and digital provisionalisation utilising angulated screw access, with a 1-year follow-up after delivery of the definitive restoration.
Materials and methods: A healthy 27-year-old woman with congenital agenesis of the mandibular second premolars and who required replacement of the mandibular left second premolar underwent immediate single-tooth replacement therapy via computer-aided, restrictive implant placement and provisionalisation using custom prosthetic components designed prior to the surgical intervention being performed.
Results: After a 6-month healing period, the provisional crown was replaced with the definitive restoration. After 1 year, the peri-implant keratinised mucosa demonstrated vertical gain in the mid-buccal portion and stability in the interproximal aspects, and no changes in marginal bone level were observed.
Conclusions: The present case report demonstrates the successful application of novel digital tools to facilitate both surgical and prosthetic aspects of immediate single-tooth replacement therapy. Digital workflows can optimise the clinical efficiency and predictability of tooth replacement therapy with dental implants by reducing surgical and restorative chair time and increasing patient satisfaction.
