Dental implants have emerged as a first line of treatment to replace missing teeth for both the edentulous and partially dentate patients. The anticipated high degree of success is somewhat challenged by the onset of peri-implantitis. Peri-implant diseases are a cluster of “contemporary” oral infections in humans; they are characterized by the inflammatory destruction of the implant-supporting ...

BACKGROUND The failure of osseointegration in oral rehabilitation has gained importance in current literature and in clinical practice. The integration of titanium dental implants in alveolar bone has been partly ascribed to the biocompatibility of the implant surface oxide layer. The aim of this investigation was to analyze the surface topography and composition of failed titanium dental impla...

Osseointegrated dental implants are now a well-established treatment option in the armament of restorative dentistry. These technologically advanced devices are designed to functionally and esthetically replace missing teeth. Despite the revolutionary advances that implants have incurred, they have also provided the oral cavity with new artificial surfaces prone to the formation of oral biofilm...

Bacteria present on implant surface may lead to an inflammation of the peri-implant mucosa, and, if left untreated, the inflammation spreads apically and results in bone loss, a process that has been named peri-implantitis (Garcia et al., 1998). So, the removal of bacterial biofilms seems to be a prerequisite in the therapy of peri-implant infections (Schwarz et al., 2005). Periodontal diseases...

PURPOSE The aim of this study was to examine whether a previous peri-implantitis site can affect osseointegration, by comparing implant placement at a site where peri-implantitis was present and at a normal bone site. A second aim of this study was to identify the tissue and bone reaction after treating the contaminated implant surface to determine the optimal treatment for peri-implant disease...

successful treatment of a large implant periapical lesion (ipl) that caused paraesthesia and perimandibular abscess. ipl is a pathologic phenomenon that rarely involves implants. this event first described in 1992 with an incidence rate of 0.26–9.9% and the origin is not well known. the most likely suggested causes are presence of preexisting bone pathology, contamination of implant surface, bo...

PURPOSE To evaluate the early bone response to a nanotextured dental implant treated with sodium sulfate (Na2SO4), using a rabbit model. METHODS Twelve animals were randomly divided into group 1 (Control) - machined implants and group 2 (Test) - nanotextured implants. Extra-oral incision was performed to provide access to intended surgical site where the dental implant was inserted immediatel...

PURPOSE This case series evaluated the implant success rate and peri-implant tissue response of immediately loaded unsplinted implants retaining a mandibular overdenture. MATERIALS AND METHODS Eight completely edentulous patients (five men, three women) with a mean age of 69.1 years were included in the study. All participants received new maxillary and mandibular complete dentures prior to i...

General term of implantation implies insertion of biomaterials of different designs into the tissues. Oral implantation is a surgical insertion of aloplastic materials (metals, alloys, ceramics, polymers, carbons as well as their combinations) into the hard and soft tissues of the upper and lower jaws . The essence of implantology lies in favorable reaction of the organism to the presence of fo...
