Biologically oriented preparation technique for surgically extruded teeth: A clinical report.

Surgical extrusion allows a ferrule to be obtained without the use of orthodontic extrusion or the need to remove hard and soft tissues. However, after the healing period, the soft tissue of the extruded tooth might become thinner, creating an unesthetic gingival margin. Unlike other preparation techniques, the biologically oriented preparation technique provides increased long-term gingival thickness. This article describes the treatment of 3 patients with teeth with no ferrule that were surgically extruded and restored with the biologically oriented preparation technique .

Guided Endodontics for Managing Severely Calcified Canals.

Endodontic treatment of teeth with pulp canal obliteration presents a challenge given the high likelihood of procedural errors and complications during treatment. These drawbacks can be avoided by using a personalized 3-dimensional (3D) guide designed by overlaying a cone-beam computed tomographic scan with an intraoral scan of the patient. This 3D guide enables the clinician to obtain a straight access to the obliterated root canal.This article described guided endodontics in managing 7 severely obliterated teeth using both virtually designed 3D guides and a customized 1-mm-diameter cylindrical bur. This treatment approach was demonstrated to be safe and fast and can be considered as a predictable technique for the location of calcified canals, thus minimizing complications.
