Many conventional types of luting cement are available for the dental clinicians to choose and restore luting of ceramic crowns. But not all the available luting cements are ideal for all situations. All ceramic restorations do benefit from resin cements bonding to the tooth. Hence it necessitates comparing the bonding ability of different luting cements to ceramic and dentin. The main objectiv...

AIM The objective of this study was to compare the film thickness of a light body polyvinylsiloxane addition silicone impression material using the "replica technique" (RT) to the film thickness resulting from the cementation of Procera copings. METHODS AND MATERIALS Twenty Procera copings were fabricated on ten casts each having one central incisor and one premolar. The thickness of the ligh...

Masquelet technique, which is the use of a temporary cement spacer followed by staged bone grafting, is a recent treatment strategy to manage a posttraumatic bone defect. This paper describes a series of 9 patients treated with this technique of staged bone grafting following placement of an antibiotic spacer to successfully manage osseous long bone defects. The injured limbs were stabilized an...

We present a case of giant osteofibrous dysplasia (OFB) of the proximal tibia with 15 years of follow-up. The tumor recurred after first biopsy and curettage done at the age of 6 years and, again, 4 years later. Following recurrence, the option of amputation was suggested. Staged treatment of curettage, cryosurgery, bone cement as a temporary spacer with internal fixation at age 12 years, follo...

Periprosthetic joint infection is a frequent complication after total hip replacement. Two-stage exchange with the use of a temporary cement spacer is commonplace. Several complications are possible with its use. In addition to infection persistence, mechanical complications such as dislocation or fractures are among the most common. Several risk factors can and should be addressed during first...

BACKGROUND Addition of antibacterial drugs to interim antibacterial cement spacers (ACSs) is considered to be standard of care for surgical revision in prosthetic joint infections (PJIs). We reviewed published studies evaluating the choice and doses of antibacterials in spacers. METHODS We conducted a PubMed search of all clinical study reports evaluating the use of ACSS in a 2-stage hip or k...

Resorbable calcium phosphate based bone void fillers should work as temporary templates for new bone formation. The incorporation of macropores with sizes of 100 -300 µm has been shown to increase the resorption rate of the implant and speed up bone ingrowth. In this work, macroporous brushite cements were fabricated through foaming of the cement paste, using two different synthetic surfactants...

Gentamicin (G) and vancomycin (V) concentrations in drainage fluids obtained from patients during the first 24 hours after implantation of antibiotic-loaded polymethylmethacrylate (PMMA) spacers in two-stage revision of infected total hip arthroplasty were studied. The inhibitory activity of drainage fluids against different multiresistant clinical isolates was investigated as well. Seven hips ...
