Immediate total tooth replacement.

Successful implant placement at the time of extraction has been documented. Implant placement at the time of extraction was initially performed as a two-stage procedure often with barrier membranes and sophisticated second-stage surgical uncoverings. The authors describe the next generation of this technique, including atraumatic tooth removal with simultaneous root form, implant placement, and temporization at one appointment. This technique of "Immediate Total Tooth Replacement" allows for the maintenance of the bony housing and soft-tissue form that existed before extraction, while at the same time establishing a root form anchor in the bone for an esthetic restoration.

Fifty years of interdisciplinary site development: lessons and guidelines from periodontal prosthesis.

Just as "osseointegration" became synonymous with successful restoration of function in the fully edentulous patient during the 1980s, the term "implant site development" has become intricately associated in the 1990s with the techniques used to achieve esthetic results with implants in the partially edentulous patient. This article explores the roots of the concept of site development within the philosophy and principles of periodontal prosthesis. In addition, the myriad of techniques that are presently collectively referred to as site development are systematically classified into a sequential four-tiered approach that optimizes their efficient application as well as overall success.

Treatment planning 2000: an esthetically oriented revision of the original implant protocol.

Soft and hard tissue ridge deformities are prevalent in areas of tooth loss and trauma and can compromise esthetic outcomes. Only a full understanding of the severity of the dimensional defects, the reconstructive techniques available, and the functional and esthetic needs of the final implant restoration will allow the design of a treatment approach that will achieve the desired outcome. This article emphasizes the synergistic relation of the osseous, gingival, and restorative triad in treatment planning. In addition, a systematic approach to the enhancement of this triad, in the partially edentulous patient, is outlined as part of a revised protocol for achieving optimal esthetics in implant therapy.

Experimental murine schistosomiasis: reduced hepatic morbidity after pre- and/or post-infection treatment with ibuprofen or diclofenac sodium.

Arachidonic-acid metabolites appear to participate in skin penetration by and transformation of schistosome cercariae and in the pathogenesis of schistosomiasis. With this in mind, mice were treated with one of two cyclooxygenase inhibitors before and/or after infection with Schistosoma mansoni. The effects of the treatment on liver morbidity and the parasitic infection were then evaluated, using infected, untreated and uninfected, treated mice as controls. Treatment with ibuprofen (20 mg/kg.day) or diclofenac sodium (2.5 mg/kg.day) for 7 days before infection led to significantly lower liver weights, worm loads and hepatic hydroxyproline contents than in the untreated mice. If treatment with either drug was continued after infection, for 28 days, there was an additional significant decrease in hepatic gamma-glutamyl transpeptidase activity. All these parameters except liver weight were similarly affected when treatment with either drug was begun on the day of infection and continued for 28 days. There was no significant change in liver weight or worm load when treatment was delayed until day 28 post-infection but faecal egg counts were reduced in the treated groups. In additional experiments, using a smaller dose of diclofenac sodium (1.25 mg/kg.day), all the measured parameters of infection were significantly decreased when the treatment was initiated 7 days before infection and continued until day 28 post-infection. The results indicate that the treatment of S. mansoni-infected mice with ibuprofen or diclofenac sodium was effective in reducing the severity of infection and in attenuating hepatic fibrosis, particularly when the treatment was started early in relation to the time of infection.

The interproximal height of bone: a guidepost to predictable aesthetic strategies and soft tissue contours in anterior tooth replacement.

Enhanced aesthetic objectives can be achieved with precision and predictability due to recent advances in restorative materials and procedures. Although these developments have expanded the therapeutic options available to practitioners and their patients, anterior hard and soft tissue deformities in the aesthetic zone continue to represent a significant technical challenge to the reconstructive team. The objective of this article is to present diagnostic and prognostic criteria that emphasize the osseous-gingival relationship as a means to achieve predictable aesthetic results in the anterior segment with conventional or implant-supported restorations.
