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.

Extrusión quirúrgica para la restauración del diente altamente comprometido: seguimiento a 3 años / Surgical extrusion to restore highly compromised tooth: 3-year follow-up

INTRODUCCIÓN: Un ferrule de 2 mm a 3600 asegura la supervivencia a largo plazo del diente restaurado. Sin embargo, existen situaciones clínicas donde el ferrule es insuficiente. Existen básicamente 3 opciones de tratamiento para la obtención de ferrule sin invadir el espacio biológico: el alargamiento de corona quirúrgico, la extrusión ortodóntica rápida y la extrusión quirúrgica. CASO CLÍNICO: EL presente caso clínico describe la restauración de un premolar inferior sin ferrule por medio de la extrusión quirúrgica, el retratamiento de conductos, y la colocación de poste y corona. CONCLUSIÓN: La extrusión quirúrgica permite, de manera altamente predecible restaurar dientes sin ferrule con raíces largas y periodontalmente sanos, sin comprometer los tejidos periodontales ni necesidad de aparatología ortodóntica

INTRODUCTION: A 2-mm ferrule over 3600 ensures a long-term survival of the restored tooth. However, there are clinical situations in which ferrule is insufficient. Thus, there are 3 treatment options to obtain ferrule without invading the biological width: surgical crown lengthening, rapid orthodontic extrusion and surgical extrusion. CLINICAL CASE: The present clinical case describes the restoration of a lower premolar without ferrule by means of surgical extrusion, root canal re-treatment, and post and crown. CONCLUSION: Surgical extrusion allows predictably the restoration of long, periodontally healthy teeth with no ferrule, without compromising the periodontal tissues or the need for orthodontic appliances

Lesión endo-periodontal: curación a tres años / Endo-periodontal lesion: a 3-year healing process

Las lesiones endo-periodontales pueden suponer un reto en el diagnóstico. Las imágenes radiolúcidas de furca acompañadas de sondajes profundos y aislados son compatibles con fracturas verticales, perforaciones o causas puramente endodónticas, es decir, abscesos periapicales crónicos con exacerbación por el surco gingival. Las perforaciones son complicaciones que afectan al pronóstico de la endodoncia y que desencadenan defectos periodontales. En el presente caso clínico se describe el retratamiento ortógrado con el sellado de una perforación en el tercio coronal de un primer molar inferior. Después de tres años de control, se observa curación radiográfica de ambas lesiones y una reducción de 6 mm en el sondaje periodontal

Diagnosis of endo-periodontal lesion can be challenging. Furcal radiolucencies accompanied with deep and isolated probings are compatible with vertical root fractures, perforations or with endodontic causes, that is to say, chronic periapical abscess exacerbated through the gingival sulcus.Perforations are complications that affect the prognosis of the root canal treatment and induce periodontal defects. The present case describes an orthograde root canal retreatment with a perforation sealing in the coronal third of a first lower molar. Three years after, a radiographic healing of both lesions and a reduction of 6mm periodontal probing is observed
