Abstract
Previous preclinical and clinical studies have demonstrated the effectiveness of precisely configured laser-ablated microgrooves placed on implant collars to allow direct connective tissue attachment to the implant surface. A recent canine study examining laser-ablated microgrooves placed in a defined healing abutment area demonstrated similar findings. In both instances, direct connective tissue attachment to the implant-abutment surface served as an obstacle to the apical migration of the junctional epithelium, thus preventing crestal bone resorption. The current case report examines the effectiveness of abutment-positioned laser-ablated microgrooves in human subjects. As in the preclinical trial, precisely defined laser-ablated microgrooves allowed direct connective tissue attachment to the altered abutment surface, prevented apical migration of the junctional epithelium, and thus protected the crestal bone from premature resorption.Entities:
