The purpose of this study was to examine the healing potential and re-osseointegration in peri-implant infection defects adjacent to various implant surfaces. In 7 female Beagle dogs, a total of 41 titanium oral implants (ITI, Straumann, Waldenburg; Switzerland) with a sink depth of 6 mm (diameter 2.8 mm) were placed transmucosally. Four different surface(More)
Legume root nodules are the site of biological nitrogen fixation in the Rhizobium-legume symbiosis. Nodules are structures unique to this symbiosis and they are morphologically as well as physiologically distinct from other plant organs. Organic substances affecting the macro- or microsymbionts vitality, such as PAHs (WETZEL: et al., 1991), reduce(More)
Periodontal probing is commonly used for assessing both the status of gingival health and the connective tissue attachment level around teeth. The role of probing around endosseous implants still remains unclear. The purpose of this study was to determine the histological level of probe penetration in healthy and inflamed mucosal tissues around implants.(More)
The placement of oral implants into jaw bone has a high predictability provided an adequate bone volume surrounding the implant is present to ensure primary stability and resistance to functional loading forces after completion of osseointegration. In the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the(More)
Shields, Joshua M. Ph.D., Purdue University, December 2013. Effects of Amur honeysuckle (Lonicera maackii [Rupr.] Herder) invasion and removal on native vegetation and white-footed mice (Peromyscus leucopus) in mixed-hardwood forests of Indiana. Major Professor: Dr. Michael A. Jenkins. The threat of non-native invasive species continues to compromise the(More)
The success of endosseous dental implants is enhanced when sufficient bone is present to stabilize the implant. If adequate bone for full coverage of the implant is not possible, then the use of guided bone regeneration to regenerate the missing bone has been shown to be a predictable solution. Defect size can often limit the amount of soft tissue available(More)
Guided tissue regeneration has been shown to establish new attachment in periodontal defects and to facilitate hard tissue repair around dental implants. This case report describes a patient treated with guided tissue regeneration adjacent to an endosseous dental implant. Histologic analysis showed the regenerated tissue to be mature, cortical bone(More)
