Dental implants have become a popular choice of treatment in replacing individual lost teeth or entire dentitions. The physical properties of high corrosion resistance, high structural strength and high melting point, suggest the retention of intact implants following most physical assaults. As the implants are machine made, they lack the individualisation required for their use as identifiers ...

This study constructs a standard in vitro laser treatment platform with dental implant thread surface on bacterial adhesion for peri-implantitis at different tooth positions. The standard clinical adult tooth jaw model was scanned to construct the digital model with 6 mm bone loss depth on behalf of serious peri-implantitis at the incisor, first premolar, and first molar. A cylindrical suite co...

BACKGROUND One-piece narrow diameter implants (NDIs) have been recommended as "Single-tooth replacements in the anterior zones, single posterior, multiple-unit fixed dental prosthesis (FDP), edentulous jaws to be rehabilitated with FDP, and edentulous jaws rehabilitation with overdentures in situations with reduced mesiodistal space or reduced ridge width." (ITI consensus 2013). Since NDIs can ...

Patients undergoing total knee arthroplasty (TKA) who have hypersensitivity to metals usually receive hypoallergenic TKA implants. Coating of a standard implant is a common solution. Although in vitro tests have demonstrated reduction in polyethylene wear for these coatings, it is unknown whether these costly implants have a clinical benefit for patients. One hundred twenty patients undergoing ...

The reliability and failure modes of molar crowns supported by three different implant-supported designs were tested according to the following groups: group 1, one standard-diameter implant (3.75 mm); group 2, one narrow-diameter implant (3 mm); and group 3, two narrow-diameter implants (3 mm). Loads were applied as mouth-motion cycles using a step-stress accelerated life-testing method. ? val...

BACKGROUND Attempts have been made to evaluate the biologic dimension of osseointegrated implants, however, most are histologic studies in animals, and the effect of soft tissue support from adjacent teeth on the interproximal dimension of the peri-implant mucosa for anterior single implants has not been addressed. This study clinically evaluated the dimensions of the peri-implant mucosa around...

background and aims. different clinical studies have reported high survival rates in immediate implant placement in extraction sockets with periapical lesions. the aim of this study was to investigate the effect of er:yag laser irradiation on success rate of immediate implant placement in tooth extraction sockets with chronic periapical lesions. materials and methods. thirty patients requiring ...

The fibular free flap, with or without a cutaneous component, is the gold standard for reconstructing mandibular defects. Dental prosthetic rehabilitation is possible this way, even if the prosthesis-based implant is still a challenge because of the many anatomical and prosthetic problems. We think that complications can be overcome or reduced by adopting the new methods of computed tomography ...

In patients with rheumatoid arthritis, metacarpophalangeal joint deformities can significantly affect hand function. Flexible hinge implant arthroplasty, designed in the 1960s, remains the most accepted and widely performed technique for treatment of severely involved metacarpophalangeal joints in rheumatoid arthritis. An arc of motion of 40 degrees to 60 degrees can be expected after arthropla...
