Full digital workflow for crown lengthening by using a single surgical guide.

A technique using a digital workflow for performing crown lengthening by using a free software program is presented to digitally design a single surgical guide. The technique consists of obtaining standard tessellation language (STL) files from intraoral scans from a digital design of the new tooth shape and from a cone beam computed tomography (CBCT) scan, after which Digital Imaging and Communications in Medicine (DICOM) files are converted to the STL format. These files are then superimposed and used for surgical planning of the crown-lengthening procedure.

Esthetic Rehabilitation through Crown Lengthening Surgery and Conservative CAD/CAM Veneers: A Multidisciplinary Case Report.

This case report describes a successful multidisciplinary approach used to improve the smile esthetics of a patient presenting with excessive gingival display, asymmetric gingival margins, and small upper anterior teeth and lower anterior teeth. The treatment combined esthetic crown lengthening, dental bleaching, and restorative dentistry using CAD/CAM veneer. The 6-month follow-up examination confirmed the stability of the modification and absence of adverse effects.

Repair of Class II furcation defects after a reparative tissue graft obtained from extraction sockets treated with growth factors: a histologic and histometric study in dogs.

Background: Reparative tissue of extraction sockets was proposed as grafting material in the treatment of periodontal defects. Our hypothesis was that the addition of growth factors to extraction sockets improves the regenerative potential of this tissue when used as a graft. The objective of the present study was to analyze qualitatively and quantitatively the repair of acute Class II furcation defects after they receive this grafting material.
