Assessment of ridge preservation with immediate implant placement using socket shield versus guided bone regeneration techniques in aesthetic zone (a randomized clinical trial) [PDF]

Alexandria Dental Journal
Background: The socket shield technique was created to protect periodontal ligament-related perfusion following tooth extraction to prevent alveolar bone resorption, which occurs as a result of a lack of blood flow caused by the loss of periodontal ...

Mechanisms of Guided Bone Regeneration: A Review [PDF]

The Open Dentistry Journal, 2014
Post-extraction crestal bone resorption is common and unavoidable which can lead to significant ridge dimensional changes. To regenerate enough bone for successful implant placement, Guided Bone Regeneration (GBR) is often required. GBR is a surgical procedure that uses barrier membranes with or without particulate bone grafts or/and bone substitutes ...

Membranes for the Guided Bone Regeneration

Maxillofacial Plastic and Reconstructive Surgery, 2014
Many kinds of membrane have been used for the guided bone regeneration (GBR) technique. However, most membranes do not fulfill all requirements for the ideal membrane for the GBR technique. Among them, collagen membrane has been most widely used. However, its high price and weak tensile strength in wet condition are limitations for wide clinical ...

Histological and histomorphometric evaluation of efficacy of a polypropylene barrier in guided bone regeneration and modified guided bone regeneration in critical defects in rodent cranial vaults

Journal of Indian Society of Periodontology, 2019
Background: The last few years have detailed a number of surgical materials and techniques to stimulate guided bone regeneration (GBR). Polypropylene has been used as a mechanical barrier, intentionally designed to be exposed to the oral environment ...

Mechano-Biological Computer Model of Scaffold-Supported Bone Regeneration: Effect of Bone Graft and Scaffold Structure on Large Bone Defect Tissue Patterning

Frontiers in Bioengineering and Biotechnology, 2020
Large segmental bone defects represent a clinical challenge for which current treatment procedures have many drawbacks. 3D-printed scaffolds may help to support healing, but their design process relies mainly on trial and error due to a lack of ...

Split crest technique for implant treatment of agenesis of the upper lateral incisors: results of a randomized pilot histological and clinical study at 24-month follow-up [PDF]

Brazilian Oral Research
Agenesis of lateral incisors, besides the functional issues, represents a great esthetic drawback. The selection of an appropriate treatment is a complex decision, which should consider the stability of the clinical outcomes over time.
