Context: Dental magnets are used for retaining removable prostheses such as a removable partial denture, complete denture, and maxillofacial prosthesis. They provide good retention for the prostheses. However, the elements released from the magnets may be cytotoxic for the tissues. Therefore, it is necessary to evaluate their cytotoxic effect on cell lines. Aim: The aim of the study is to check the cytotoxic effect of indigenously fabricated dental magnets on animal cell lines...

Even dentures exhibiting superb aesthetics are of no use if they visibly move during speech and social intercourse. In this, the second paper of three on removable denture aesthetics, we describe impression making and shaping the wax occlusal record rims. Not only are the impressions important for producing dentures with maximum retention, stability and support, but their extensions and the thickness of their borders have a decisive influence on lip support and profile. This article shows how the contours of the definitive impressions and the wax rims are developed so as to prescribe the overall form of the replacement gums and teeth...

Dentinogenesis imperfecta (DI) is a hereditary condition that may affect both primary and permanent dentition and is characterized by abnormal dentin formation. The teeth may be discolored with chipping of enamel and, in untreated cases, the entire dentition may wear off to the gingiva. This may lead to the formation of abscesses, tooth mobility, and early loss of teeth. In the Indian population, DI is found to have an incidence of 0.09%. Treatment of DI should aim to remove infection, if any, from the oral cavity; restore form, function, and esthetics; and protect posterior teeth from wear for maintaining the occlusal vertical dimension...

Introduction: Treatment of edentulous atrophic mandible with severe atrophy is a challenge based on local conditions and systemic diseases confronted by the age group affected. If bone grafting is indicated, it is often used in lateral or inferior aspects of the mandible. Case Report: A 70-year-old male with a unilateral fracture of the atrophied left mandibular body was managed by lingual bone grafting and inferior border miniplate fixation to prevent two common problems after fracture healing; the need for plate removal before denture fabrication and facial asymmetry in the unilateral body fracture...

Introduction: Aspirated foreign bodies continue to present challenges to otorhinolaryngologists. Removal of impacted airway foreign bodies via conventional methods can at times pose difficulty. This may be related to the location and type of foreign body, experience of the surgeon and anesthetist, and the availability of appropriate instruments. In adults, especially in edentulous patients, a swallowed denture usually gets lodged in the esophagus and entrance into the airway is uncommon...

Demographers agree that the so-called elderly population will increase steadily in the future. Not only will their numbers increase, but they will live to an older age. In the case of fully edentulous patients, implant treatment is a possibility, but for many, rehabilitation by means of full removable dentures is still the preferred option. In recent decades, computer-aided design/computer-aided manufacturing (CAD/CAM) has brought about what can only be described as a revolution in dental offices and dental laboratories...

BACKGROUND: The success of prosthetic rehabilitation in patients with removable dentures depends on the achievement of the aesthetics, phonetics and most of all, proper use in the mastication process. All the patients that receive removable prostheses need a feeding education program. They must cut the food into smaller pieces, extend the length of time necessary for chewing and place the food upon both the right and left sides of the mouth at once. Bilaterally chewing with dentures will contribute to increased efficiency and denture stability during mastication...

Patients requiring dentures are getting older and as a result can be difficult to treat owing to various co-morbidities. This series of papers presents an overview of the processes involved in making removable dentures which the patient considers to be functionally and aesthetically successful. We hope not only to provide technical suggestions but also to address the issue of the clinician's, technician's and dental nurse's relationships with the dentally depleted patient. It is increasingly clear from defence organisation reports that this has a decisive effect on the success of this fundamentally difficult enterprise ('The only branch of dentistry in which you are trying to attach something to nothing' [Hubert Aïche])...
