Enhanced Lateral Bone Augmentation With a Perforated Resorbable Barrier Membrane

Clinical Advances in Periodontics
Julio A CarrionVincent J Iacono

Abstract

To the best of the authors' knowledge, this is the first case report to describe the use of a perforated resorbable barrier membrane (PRBM) to enhance lateral bone augmentation for implant site development. A 41-year-old female presented to the Advanced Specialty Education Program in Periodontics at Stony Brook University, Stony Brook, New York, for implant consultation regarding a missing maxillary right lateral incisor. The tooth had been lost as a result of trauma 10 years prior to presentation. Clinical examination and radiographs showed significant horizontal ridge deficiency (<5 mm) that supported a staged intervention. Horizontal bone augmentation was performed following guided bone regeneration principles using a mineralized mixed corticocancellous (70:30) allograft followed by a PRBM. A cone beam computed tomography scan was obtained before surgery and 8 months after treatment, from which volumetric width changes were quantified. A bone biopsy was obtained at the time of implant placement to measure new vital bone (NVB) formation, residual graft (RG) particles, and connective tissue (CT) formation. Dimensional width changes were assessed during reentry for implant placement. The lateral bone gain was 5.0 mm, clinically...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
