The ideal placement of implants is not always possible in partially edentulous patients. The diverse and unique implant positions that occur in clinical practice may be difficult or impossible to restore through the use of conventional abutments. Customized abutments permit the fabrication of aesthetic restorations that correct deficiencies in implant(More)
Toxic-shock syndrome (TSS) is believed to be caused by a toxin produced by Staphylococcus aureus. An exotoxin has been identified that is associated with strains of S. aureus isolated from patients with TSS. Coded strains of S. aureus were tested for the presence of the exotoxin by polyacrylamide gel isoelectric focusing. Sixty isolates of S. aureus were(More)
Textured implant surfaces are thought to enhance endosseous integration. Torque removal forces have been used as a biomechanical measure of anchorage, or endosseous integration, in which the greater forces required to remove implants may be interpreted as an increase in the strength of bony integration. The purpose of this study was to compare the torque(More)
Roughened implant surfaces are thought to enhance osseointegration. Torque removal forces have been used as a biomechanical measure of anchorage or osseointegration in which the greater forces required to remove implants may be interpreted as an increase in the strength of osseointegration. The purpose of this study was to compare the torque resistance to(More)
STATEMENT OF PROBLEM The success rates of osseointegrated implants used to restore patients who were irradiated for head and neck tumors are influenced by radiation-induced changes in the hard and soft tissues. PURPOSE This article examined, by review of the literature, current perspectives on the restoration of irradiated patients using osseointegrated(More)
A clinical study of 40 craniofacial implants placed in 13 auricular defects was conducted over a 6-year period. Implant-retained prostheses were fabricated, the implant success rate was determined, and the soft tissue responses were recorded at regular intervals. All of the implants became osseointegrated and none demonstrated failure during the study(More)
PURPOSE Fabricating a maxillary obturator can be challenging. Placement of implants can have a dramatic effect on the stability and retention of the prosthesis in the edentulous maxillectomy patient. This article provides clinical retrospective analysis of osseointegrated implants used to retain maxillary obturators. MATERIAL AND METHODS Patient charts(More)
Reconstructive procedures are able to provide improved aesthetics for implant patients who present with anatomical limitations (e.g., vertical or horizontal tissue loss) in the anterior maxilla. Aesthetic results, however, are directly related to the ability of the treatment team to reconstruct the lost bone and soft tissue, place the implant into its(More)
A clinical study of 23 craniofacial implants placed in 11 nasal defects was conducted over a 7-year period. Implant-retained nasal prostheses were fabricated, implant success rate was determined, and the soft tissue responses were recorded at 6-month intervals. No data were gathered on two implants because of patient death. The implant success rate was(More)
