Introduction: Langerhans cell histiocytosis (LCH) refers to a group of rare reticuloendothelial system disorders and it occurs most often in young adults and children. A 57-year-old edentulous female patient who complained of dull pain in the posterior region of the mandible referred to the dental office, with a complaint of dull pain in the posterior region of the mandible. The lesion was diag...

BACKGROUND To evaluate the bone mineral density in the mandible of edentulous patients at prospective intraoral implant sites. Pre-operative evaluation of bone density is essential to assist the clinician with the treatment planning of implant supported prosthesis. MATERIALS AND METHODS A study group of 12 edentulous subjects comprising of six male and six female between the age group of 45-5...

Alveolar bone loss (RRR) is a continuous process following tooth extraction, more pronounced during the first few months after the tooth extraction than later. The RRR in the mandible is twice that of the maxilla during a 1-year period and the mandibular: maxillary resorption ratio increases further to 4:1. So far, the etiology of RRR has not been elucidated. It has been speculated that both sy...

Edentulous patients with a severely resorbed mandible often experience problems with their dentures. Treatment concepts involving two to four implants for the support of an overdenture have been proposed. The aim of this study was to develop a treatment concept for mandibular overdentures supported by endosseous implants based on a review of the literature. It is proposed that two implants supp...

Segmental resection of the mandible commonly results in deviation of the mandible to the defective side. The amount of deviation depends on the amount of hard and soft tissue involvement, the method of surgical site closure, the degree of impaired tongue function, the number of remaining teeth and the extent of loss of sensory and motor innervations. Prosthodontic treatment along with physical ...

PURPOSE The aim of this study was to obtain statistical data on the residual bone height at different natural tooth positions by panoramic radiography in edentulous Korean patients aged 60-90 years. MATERIALS AND METHODS The study included the diagnostic panoramic radiographs of 180 randomly selected edentulous patients without systemic diseases affecting bone. The radiographic selection crit...

OBJECTIVES To study the prevalence and the degree of lingual concavity in the edentulous first molar region from cone beam computed tomography (CBCT) scans of the mandibles. MATERIAL AND METHODS Qualified cross-sectional images in mandibular first molar edentulous region taken from CBCT were selected. The mandible morphology 2 mm above the inferior alveolar canal (IAC) was classified into the...

Our earlier studies on edentulous elderly subjects have shown associations of severe resorption in the mandibular residual ridge with female gender and systemic diseases. The aim of this study was to examine whether other factors also were related to residual ridge resorption (RRR). Among 177 edentulous elderly subjects effects on RRR were investigated with regard to history of edentulousness a...

An implant-retained overdenture retained with 2 implants placed in the anterior edentulous mandible is a simple and predictable treatment option. The fabrication and use of this prosthesis requires satisfactory interarch space for adequate denture base thickness and esthetics. This clinical report describes the use of low-profile attachments for this overdenture design to solve the problem of l...

Atrophic edentulous mandible fractures represent a subset of facial injuries that are more commonly sustained by older victims. Perioperative management of the acutely injured elderly patient is different from the management of younger patients, and is often described as more complex.1,2 Physiologic and anatomic changes attendant to complete edentulism in the mandible, and the metabolic effects...
