Immediate loading of oral implants is an established concept for lower jaw restoration using four intraforaminal implants splinted together with a bar. There is a lot of misunderstanding in the literature and not exact definition of the term "immediate loading." Moreover, the number of implants to restore edentulous jaws is relatively high to compensate for the loading forces and dependent on t...

Higher animals typically rely on calcification to harden certain tissues such as bones and teeth. Some notable exceptions can be found in invertebrates: The fangs, teeth, and mandibles of diverse arthropod species have been reported to contain high levels of zinc. Considerable quantities of zinc also occur in the jaws of the marine polychaete worm Nereis sp. High copper levels in the polychaete...

Purpose. The aim of this study was to analyze the clinical and radiographic outcomes of 23 edentulous jaws treated with 3D software planning, guided surgery, and immediate loading and restored with CAD-CAM full arch frameworks. Materials and Methods. This work was designed as a prospective case series clinical study. Twenty patients have been consecutively rehabilitated with an immediately load...

BACKGROUND The pre-operative evaluation in oral and maxillofacial surgery is currently performed by computerized tomography (CT). However in some case the information of the traditional imaging methods are not enough in the diagnosis and surgical planning. The efficacy of these imaging methods in the evaluation of soft tissues is lower than magnetic resonance imaging (MRI). AIM The aim of the...

introduction: giant cell lesions of the bone comprise a group of jaw bone pathologies. different pathogeneses such as reactive, vascular or neoplastic have been proposed for these lesions. in addition, differentiating between aggressive and nonaggressive central giant cell granuloma (cgcg) of the jaws based on histopathologic features is still impossible and due to different treatment protocols...

BACKGROUND The clinicopathologic characteristics of multiple ossifying fibroma (OF) are unclear due to the condition's rarity, making diagnosis challenging. Sporadic multiple OFs must be distinguished from hyperparathyroidism-jaw tumour syndrome (HPT-JT) related OF and other fibro-osseous lesions. METHODS Multiple OF cases were identified from ossifying fibroma cases. Clinical data including ...

Clear cell carcinoma rarely appears in the jaws. We here reported two possible cases of such rare carcinoma. Microscopic examination and the clinical features indicated case NO. I being a renal cell carcinoma metastasized to the mandible, and case NO.2 being a primary acinic cell carcinoma originated from the minor salivary gland.

Patients diagnosed with jaw deformity after middle age often have periodontal disease and missing teeth. In such cases, prosthetic treatment is required in addition to orthodontic treatment. Therefore, surgical for middle-aged patients requires a more careful approach than younger patients. This report of two representative cases. Case 1: A 51-year-old male patient the chief complaint masticato...

Chronic osteomyelitis of maxilla and mandible is rare in industrialized countries and its occurrence in developing countries is associated with trauma and surgery, and its microbial etiology has not been studied thoroughly. The aim of this investigation was to evaluate the microbiota associated with osteomyelitis of mandible or maxilla from some Brazilian patients. After clinical and radiograph...

BACKGROUND There is limited evidence for the outcome of short implants (7 mm) to rehabilitate posterior jaws. PURPOSE To report on the outcome of 7 mm short implants in the rehabilitation of posterior areas of atrophic jaws 1 year after loading. MATERIALS AND METHODS This prospective study included 127 patients treated with 217 implants supporting 165 fixed prostheses. Final abutments were ...
