distal extension removable partial denture is a prosthesis with lack of distal dental support with a 13-fold difference in resiliency between the mucosa and the periodontal ligament, resulting in leverage during compression forces. it may be potentially destructive to the abutments and the surrounding tissues. the aim of this study was to assess the effect of implant location on stress distribu...

The prevention of periodontal disease is a key factor in oral health. It has also become evident that periodontal health is associated with systemic health. Nonsurgical scaling and root planing is the standard of care for periodontitis. Supragingival plaque removal influences the bacterial environment in pockets up to 3 mm in depth, while subgingival scaling and root planing is essential in poc...

BACKGROUND The advantages of platform switching using narrower abutments remain controversial. Many researchers suggest that platform switching can yield enhanced clinical results, while others remain skeptical. We hypothesize that the effectiveness of platform switching might be associated with the degree of reduction in size of the abutment. PURPOSE To radiographically and clinically examin...

BACKGROUND Indigenous Australians experience an overwhelming burden of chronic disease, including cardiovascular diseases. Periodontal disease (inflammation of the tissues surrounding teeth) is also widespread, and may contribute to the risk of cardiovascular diseases via pathogenic inflammatory pathways. This study will assess measures of vascular health and inflammation in Indigenous Australi...

The 1-piece, implant-supported abutment and crown, colloquially described as the UCLA abutment, commonly is used to fabricate single, screw-retained crowns. This abutment was designed to allow attachment of the crown directly to the implant and requires a waxing and casting procedure by a laboratory technician. A new prefabricated abutment has been developed that uses a similar approach but doe...

PURPOSE The purpose of this study was to observe and compare any loosening of screws attaching several interchangeable abutments to internally connected implants after cyclic loading. MATERIALS AND METHODS Four different abutment groups mated with Straumann single-stage transmucosal implants (n = 7 each group) were assessed: Straumann solid abutment, Restore COC abutment, Neoplant solid abutm...

OBJECTIVES There is a strong body of evidence to support the relationship between periodontal diseases and diabetes mellitus. Unless dental practitioners are aware of this link, they cannot apply the information to their daily practice. The aim of the study was, therefore, to evaluate the knowledge of dental practitioners concerning the effect of diabetes on periodontal health. SUBJECTS AND M...

Gingivitis and chronic periodontitis are highly prevalent chronic inflammatory diseases. Gingivitis affects the majority of people, and advanced periodontitis is estimated to affect 5-15% of adults. The detection and diagnosis of these common diseases is a fundamentally important component of oral health care. All patients should undergo periodontal assessment as part of routine oral examinatio...

UNLABELLED Periodontal health can be restored through assessment, diagnosis, treatment and management of periodontal osseous defects by the periodontist-dental hygienist team. BACKGROUND AND PURPOSE Treatment of periodontitis has evolved over time, with regenerative periodontal therapy at the forefront in cutting-edge periodontal care. While the techniques and materials available today are al...

Four different orthodontic applications of a polyethylene fiber material are shown and discussed in case reports. Ribbond (Ribbond Inc, Seattle, Wash), a bondable, reinforced polyethylene fiber material, was successfully used in a fixed orthodontic retainer, a space maintainer, a temporary postorthodontic fixation device to attach a pontic to abutment teeth during periodontal therapy, and a pos...
