Prospective evaluation of immediate and delayed provisional single tooth restorations.

J Oral Maxillofac Surg

November 2009

Department of Oral and Maxillofacial Surgery, LSU School of Dentistry, Louisiana State University, New Orleans, LA, USA.

Purpose: The purpose of this study was 2-fold: to determine whether there is a significant difference in the hard and soft tissue response comparing immediate with delayed implant placement after tooth removal, with immediate provisionalization, in maxillary anterior sites; and to determine and compare the crestal bone levels as the primary endpoint variable for implants placed and immediately temporized in extraction sites, to implants placed into extraction sites after the extraction site has been grafted and healed for 4 months, all immediately restored with an anatomic provisional restoration. This aim was to be evaluated by measuring crestal bone levels on standardized digital radiographs of the implants, using implant threads as a monitor of magnification and a pre-extraction reference. Secondary endpoint variables include soft tissue measures compared with method.

Many clinicians consider the prosthetic restoration of missing posterior teeth by means of a 5-unit fixed partial denture with a pier abutment a non-favorable situation. The present article assesses the validity of the pier abutment by means of a critical review of the literature and mathematical analysis of the forces generated within a fixed partial denture of this design. Few studies are available, and none substantiate the theory that the pier abutment serves as a fulcrum.

Adhesive cementation of chairside CAD/CAM inlays and onlays.

January 2006

Department of Operative Dentistry and Biomaterials, LSU School of Dentistry, New Orleans, LA, USA.

Chairside CAD/CAM restorations offer aesthetic, functional, biocompatible, and long-term successful alternatives to traditional materials and techniques, and can be fabricated in one appointment. Adhesive cementation is key for the long-term clinical success of CAD/CAM inlays and onlays. The clinical use of a newly developed composite resin cement for adhesive cementation of CAD/CAM inlays/onlays has been described.

Reconstruction of severe anterior maxillary defects using distraction osteogenesis, bone grafts, and implants.

J Oral Maxillofac Surg

March 2005

Department of Oral and Maxillofacial Surgery, LSU School of Dentistry, New Orleans, LA 70119, USA.

Purpose: The purpose of this article is to describe the method for reconstructing patients with severe anterior maxillary defects, using a combination of distraction osteogenesis, onlay bone grafts, and implants to support either fixed or fixed/removable prostheses.

Materials And Methods: The surgical technique involves placement of an extraosseous distraction device followed by greater than 10 mm of distraction of the alveolus. A corticocancellous graft is harvested from the hip to establish sufficient horizontal bone for implant placement.

The few clinical long-term studies published on all-ceramic posterior crowns indicate a favorable trend. In light of the well-documented longevity of conventional PFM crowns, however, more randomized controlled clinical long-term trials are necessary for one to recommend any technique or material over another.

The clinical long-term success of ceramic restorations--Part I: Inlays and onlays.

Department of Prosthodontics, LSU School of Dentistry, New Orleans, Louisiana, USA.

Ceramic inlays and onlays have significant aesthetic and biologic benefits. Long-term clinical studies on the success of ceramic inlays and onlays, however, provide only limited observation periods, considering that such restorations rely on current and constantly improving adhesive bonding techniques. Alternative materials, such as cast-gold restorations, have a long history of documented clinical success, which should be taken into consideration when making decisions on proper restorative material selection.

Cell-spreading assays.

Methods Mol Biol

April 2005

LSU School of Dentistry, Department of Cell Biology and Anatomy, New Orleans, LA, USA.

A method is provided to quantitate the extent of cell spreading as a function of the expression level of transfected recombinant proteins. This chapter contains protocols for 1) replating and staining transfected cells for immunofluorescence microscopy, 2) optimizing image acquisition so that fluorescence intensity can be measured independent of cell morphology, and 3) quantitating cell area and expression levels of recombinant proteins for individual transfected cells using ImagePro-Plus software. This method can be used to further our understanding of intracellular signals and protein interactions that regulate cell spreading.

Perceptions of dental schools from within and outside the university.

November 2004

Department of Periodontics, LSU School of Dentistry, 1100 Florida Avenue, Box 138, New Orleans, LA 70119-2799, USA.

Perceptions of dental schools held by high-level administrators of their parent institutions and officials in the local community have great potential to influence the future of dental education. The intent of this investigation was to gain a preliminary knowledge of such perceptions at seven institutions in the United States and to use this information to formulate hypotheses that can provide the basis for further targeted investigations that provide evidence useful in decision making and planning processes within dental schools. Interviews with university administrators, executive directors of state dental associations, and state government officials in seven areas of the United States were conducted.

September 2003

Department of Prosthodontics, LSU School of Dentistry, New Orleans, Louisiana, USA.

The indications for implant dentistry continue to increase, enabling the restoration of partially and totally edentulous patients with greater success and predictability. Recent goals for implant dentistry include simplifying the involved procedures, reducing the duration of therapy for the patient and clinician, and enabling the use of conventional prosthodontic techniques for implant-supported restorations. This article reviews key developments in implantology and highlights the various design characteristics of internal abutment connection implants, demonstrating their clinical application in a detailed case presentation.

Patient demands for improved esthetics have prompted the development of all-ceramic restorative systems for dental implants, but material strength and restorative costs have presented clinical challenges. Therefore, a new restorative system with tooth-shaped ceramic copings for the anterior and premolar jaw regions has been introduced to address these problems. Fatigue and 17o.

Department of Operative Dentistry and Biomaterials, LSU School of Dentistry, New Orleans, LA 70119, USA.

Purpose: To compare the microleakage and bond strength exhibited by two light-cured, filled dentin bonding agents, a resin cement, and cavity varnish.

Materials And Methods: The four test groups of lining agents for amalgam restorations included (LF) Light-cured, Filled resin (Clearfil Liner Bond 2); (LCF) light- and chemical-cured, Filled resin (Clearfil Liner Bond + Protect Liner); (RC) Resin Cement (Panavia 21); and (V) Varnish (Copalite). For each group, 20 Class V cavity preparations were cut in human extracted molars.
