Guided tissue regeneration using a bioresorbable matrix barrier.

Bioresorbable barrier material, used in guided tissue regeneration, changes the conventional two-stage surgery to a single-step procedure. This article presents a general surgical protocol for application of a bioresorbable matrix barrier (Guidor AB, Huddinge, Sweden). Three case reports are used to illustrate the surgical treatment of a Class II furcation defect, an intrabony defect, and a recession type defect. The learning objective of this article is to enhance the knowledge of surgical procedures and bioresorbable barrier membranes available.

[Surgical augmentation of alveolar clefts with connective tissue autografts]. / Comblement chirurgical des fentes alvéolaires par autogreffe conjonctive.

A more or less important alveolar gap is often seen after the surgical treatment of clefts. The connective tissue autograft corrects the functional and aesthetic defect of the residual lesion and a fixed prosthetic restoration can be realized.

[Orthodontic and periodontal considerations for labially placed canines in cleft lip and palate]. / Considérations orthodontiques et parodontales pour la mise en place des canines en bordure des fentes labio-alvéolaires.

Clefts can present themselves at any time after the eruption of the permanent teeth. The authors describe methods for managing these defects which include both orthodontic movement and periodontal therapy. The treatment differs depending on the dimension of the clefts and its location.
