Alveolar ridge reconstruction with a digitally customized bone block allograft.

Background: Reduced alveolar ridge volume is an often consequence after tooth loss, compromising implant placement and prosthetic rehabilitation. The digital customization of bone block allografts (BBA) is an alternative that incorporates advantages such as intimate contact with the recipient bed, increasing graft stability and reduced surgical time. In addition, enamel matrix derivate (EMD) has attracted interest for its effect on osteogenic gene expression and cell adhesion; few studies have focused on the benefits of bone regeneration with EMD.

Periodontal regeneration by minimally invasive procedures and its influence on pulp status.

Unlabelled: Dental pulp and periodontium have different communication routes including, e.g., apical foramen, accessory canals and dentin tubules.

Clinical and microbiological assessment in a subpopulation of young Argentine patients with severe periodontitis.

Unlabelled: Aggressive periodontitis (AP) is the most serious entity of periodontal disease (stage III/IV, grade C periodontitis according to the latest classification, 2017).

Aim: to enhance knowledge of periodontal microbiota in AP in native Argentine patients and describe the effect of a combined pharmacologicalmechanical periodontal treatment on clinical and microbiological parameters.

Materials And Method: The study analyzed 42 periodontal sites in 11 patients diagnosed with AP.

The Effects of Alloplastic Bone Substitute and Enamel Matrix Derivative on the Preservation of Single Anterior Extraction Sockets: A Tomographic Evaluation.

This study was designed to assess the use of enamel matrix derivative (EMD; Emdogain, Straumann) and alloplastic bone substitute (BoneCeramic [BC], Straumann) in postextraction alveolar sockets. A total of 45 patients requiring anterior single tooth extractions and subsequent implant placement were recruited and randomly assigned to one of three treatment groups. Postextraction sockets were filled with BC or BC + EMD, or were left to heal spontaneously.

The Effect of an Alloplastic Bone Substitute and Enamel Matrix Derivative on the Preservation of Single Anterior Extraction Sockets: A Histologic Study in Humans.

This study was designed to assess the effect of enamel matrix derivative (Emdogain, Straumann) and alloplastic bone substitute (BoneCeramic, Straumann) on new bone formation in postextraction alveolar sockets. Twenty-one patients requiring anterior single-tooth extractions and subsequent implant placement were recruited and randomly assigned to one of three treatment groups. Postextraction sockets were filled with either an alloplastic bone substitute (BoneCeramic [BC]), BC combined with Emdogain (EMD+BC), or left to heal spontaneously (SO).

Alveolar dimensional changes relevant to implant placement after minimally traumatic tooth extraction with primary closure.

The purpose of this study is to evaluate the dimensional changes that occur in the alveolar ridge after minimally traumatic tooth extraction by means of computed tomography (CT), with special focus on the portion of bone supporting the gingival zenith. Twenty subjects with indication for singlerooted tooth extraction and preserved alveolar walls were selected for this study. After a minimally traumatic extraction, two CT scans were performed; the first within 24 hours postextraction (TC1) and the second 6 months (TC2) later.

A method for measuring post-extraction alveolar dimensional changes with volumetric computed tomography.

The aim of this study is to present a predictable method for evaluating dimensional changes in the alveolar ridge through cone beam computed tomography (CT). Twenty subjects with single-rooted tooth extraction indication were selected for this preliminary report, which is part of a larger ongoing investigation. After extraction, two CT scans were performed; the first within 24 hours post-extraction (TC1) and the second 6 months (TC2) later.
