The aim of this in vitro study was to evaluate the early cell response and protein adsorption elicited by the argon plasma treatment of different commercially available titanium surfaces via a chair-side device. Sterile disks made of grade 4 titanium (n = 450, 4-mm diameter) with 3 surface topographies (machined, plasma sprayed, and zirconia...

Background: Altering surface characteristics by increasing its energy and hydrophilicity will accelerate the interaction between cells and implant surface. Energy and hydrophilicity tend to disappear over a short time. The implant surface may be reactivated by the use of argon plasma Objective: To assess bone density at cleaned and activated...

Objective: To assess the influence of a collagen membrane covering a perforation of the sinus (Schneiderian) membrane on the outcome (bone fill) of a sinus floor elevation. Materials and Methods: Eighteen Pelibuey sheep were used. The animals underwent sinus floor elevation on both sides of the upper jaw. A perforation of 5 9 4 mm in dimension...

Objective: To histologically assess the hard and soft tissue changes after insertion of cleaned and activated titanium implants using plasma of argon. Materials and methods: Eight dogs were included in this study. The mandibular premolars and first molars were extracted. For each hemi-mandible, four implants, 7 mm long and 3.3 mm of diameter,...

Background: Due to the lack of data on bone-to-graft contact (BGC) over time in the various regions within the subantral space of the augmented sinus floor, the present study aimed to evaluate the osteoconductivity of deproteinized bovine bone mineral (DBBM) with granules of different sizes applied in maxillary sinus floor elevation. Methods: A...
