Schubert, Oliver; Beuer, Florian; Schweiger, Josef; Gueth, Jan (2019): Digital Tissue Preservation Concept: A Workflow for Guided Immediate Implant Placement and Restoration. In: Journal of Prosthodontics-Implant Esthetic and Reconstructive Dentistry, Vol. 28, No. 6: pp. 613-617

The digital workflow presented here allows for fabrication and placement of a definitive custom abutment at the time of tooth extraction and guided immediate implant placement, thus preserving soft tissue anatomy. Since abutment design was based on the shape of the original tooth, it represented a de facto emergence-analog that provided ideal soft tissue support. The approach of superposing and merging of custom abutment design data with data captured intraorally after abutment placement enabled a digital impression without gingival displacement and associated trauma. The generated data facilitated the fabrication of a precisely fitting restoration concurrent with the implant healing period.
