Does the Outcome of Graft Materials at Dental Implant Sites Differ Between Patients With Normal and Compromised Bone Health?

The objective of this paper was to assess the outcome of bone graft material at alveolar bone augmentation sites combined with dental implants in postmenopausal women with compromised bone health by evaluating cone beam computerized tomography (CBCT) scans at multiple time points.CBCT scans were analyzed on 55 postmenopausal women with compromised bone health status to determine the fate of alveolar bone augmentation. CBCT scans were taken immediately after surgery and 9 and 24 months postoperatively.

A review of the association between osteoporosis and alveolar ridge augmentation.

Objective: Because of increasing life expectancy and popularity of dental implants, surgeons face a larger number of osteoporotic patients who require bone augmentation. Relationship between low bone density/osteoporosis and bone graft success is still not clear. The purpose of this article is to review and summarize the literature regarding the success of alveolar bone augmentation in osteoporosis.

Design and use of a prefabricated fiber-reinforced composite substructure for the chairside replacement of missing premolars.

Fiber-reinforced resin composites (FRCs) have been used to make frameworks to support particulate resin composite veneers in the replacement of missing teeth. Both prosthetic laboratory-fabricated and chairside-fabricated approaches have been used with varying degrees of success. The chairside FRC fixed partial denture has been mainly used for anterior tooth replacement where the emphasis is on esthetics rather than withstanding occlusal load.

Use of a prefabricated fiber-reinforced composite resin framework to provide a provisional fixed partial denture over an integrating implant: a clinical report.

The development of fiber-reinforced composites offers new possibilities in minimally invasive tooth replacement approaches. This article describes the use of a prefabricated fiber-reinforced composite resin framework for the chairside fabrication of a provisional fixed partial denture over an integrating implant. The framework fabrication, theory, and a clinical scenario are illustrated.

Fiber-reinforced composite prostheses.

Metal-free prosthetic dentistry continues to gain interest. Although the metal alloys contribute great strength and stiffness to restorations and prostheses, they do so at a considerable esthetic liability. Two somewhat divergent metal-free approaches to fixed tooth replacement continue to be developed for a variety of clinical applications.

Clinical evaluation of fiber-reinforced fixed bridges.

Background: This study evaluated the clinical performance of 39 light and heat polymerized fixed partial bridges made with a substructure of preimpregnated, unidirectional fiber-reinforced composite, or FRC, veneered with a hybrid particu late composite.

Methods: The authors evaluated 22 extracoronal, full-coverage retainer prostheses and 17 intracoronal, partial-coverage retainer prostheses placed over a 37-month period. All substructures initially were fabricated with a low-volume FRC.

The design and fabrication of fiber-reinforced implant prostheses.

The use of fiber composite technology in the creation of metal-free implant prostheses may solve many of the problems associated with a metal alloy substructure such as corrosion, toxicity, complexity of fabrication, high cost, and esthetic limitations. Laboratory and clinical research evaluating glass fiber-reinforced composite prostheses used to restore and replace teeth has shown that these materials exhibit excellent mechanical properties and can form a chemical bond to resin-based veneer materials such as those used in the fabrication of certain types of implant prostheses. Two different designs of fiber-reinforced composite implant prostheses have been developed and placed in human subjects.
