The neurofibrillary tau pathology and amyloid deposits seen in Alzheimer's disease (AD) also have been seen in bacteria-infected brains. However, few studies have examined the role of these bacteria in the generation of tau pathology. One suggested link between infection and AD is edentulism, the complete loss of teeth. Edentulism can result from chronic periodontal disease due to infection by ...

UNLABELLED The aim of the present study is to compare the histological aspects of bone formation in atrophic posterior mandibles augmented by autologous bone block from chin area with corticocancellous bone block allograft used as inlays with the sandwich technique. MATERIALS AND METHODS Sixteen patients with bilateral partial edentulism in the posterior mandible were selected. The residual b...

Prosthodontics is concerned with the impact of tooth or tissue damage and partial or complete loss of teeth on oral function in its broadest sense. It deals with this largely through prosthetic replacement. The discipline occupies a major portion of a dental school curriculum, and dental practitioners usually devote much of their practice to prosthodontic services. With the rapid improvement in...

BACKGROUND Implant-supported restorations have become the most popular therapeutic option for professionals and patients for the treatment of total and partial edentulism. When implants are placed in an ideal position, with adequate prosthetic loading and proper maintenance, they can have success rates >90% over 15 years of function. Implants may be considered a better therapeutic alternative t...

AIMS To evaluate the success of the osseointegration of dental implants in patients with severe maxillary atrophy after sinus lift augmentation and onlay graft surgery with autologous bone grafts. DESIGN A descriptive and analytic study of 27 patients with severe maxillary atrophy and partial or total edentulism, after 4 years follow-up. All cases underwent to autologous bone graft sinus lift...

The use of dental implants to assist in the treatment of partial and complete edentulism is well documented. Most of the implant literature, however, reports results associated with implant survival and success when there has been adherence to rigid placement and loading protocols. Conventionally, these protocols call for the undisturbed healing of the implant—3 months in the mandible and 4 to ...

Mastication is achieved through the action of multiple organs working together, including the teeth, periodontal tissue, masticatory muscles, temporomandibular joints, lips, cheeks, palate and tongue. In particular, the tongue plays a major role in the preparation phase of mastication, which includes the transport of food to the occlusal surfaces of molars and transferring the food bolus to the...

18 INTERNATIONAL DENTISTRY SA VOL. 9, NO. 5 Modern RPDs need to redeem the unfavourable reputation of their predecessors. They need to be able to hold their own in terms of comfort, aesthetics and function while safeguarding oral health. To achieve this, RPDs require both considered prosthodontic treatment planning and careful design. Most RPD frameworks are designed in the dental laboratory wi...
