background patients with thalassemia major and intermedia are susceptible to osteopenia and osteoporosis. the mechanism of osteoporosis in these patients is multifactorial. transfusion related iron overload in endocrine organs leads to impaired growth hormone secretion, diabetes mellitus, hypothyroidism, hypoparathyroidism, lack of sex steroids and vitamin d deficiency that contribute to impair...

Objective: To compare between implant retained overdenture with two different attachments by measuring : Retention. Bone changes radiographic evaluation. Subjects and Methods: Eight completely edentulous patients were selected from the Outpatient Clinic of Prosthodontic Department; Faculty Dental medicine, Al Azhar University classified into equal groups. Each patient in groups received implant...

A variety of surgical techniques and materials have been developed to increase the vertical bone height in the posterior maxilla. Minimally invasive crestal approaches for the elevation of the floor of the sinus using a crestal approach have been recently reported to minimize adverse events associated with the use of the osteotome technique for indirect sinus lift. The aim of this study is to r...

background and aims. furcally-involved teeth present unique challenges to the success of periodontal therapy and influence treatment outcomes. this study aimed to assess to compare use of adm and connective tissue membrane in class ii furcation defect regeneration. materials and methods. 10 patient with 2 bilaterally class ii furcation defects in first and/or second maxilla or man-dibular molar...

Post-extraction crestal bone resorption is common and unavoidable which can lead to significant ridge dimensional changes. To regenerate enough bone for successful implant placement, Guided Bone Regeneration (GBR) is often required. GBR is a surgical procedure that uses barrier membranes with or without particulate bone grafts or/and bone substitutes. There are two approaches of GBR in implant ...

Tooth restorations using implant-supported prostheses for functional and esthetic rehabilitation of patients has become an established and widely used treatment modality in modern dentistry. Preservation of peri-implant bone is one important factor for success. The quantity and quality of the bone surrounding an implant not only affect implant osseointegration, but also influence the shape and ...

Tooth extraction is usually followed by bone reduction. In the maxillary posterior region, this remodelling combined with sinus pneumatisation and periodontal defects may lead to a reduced basal bone height available for implant placement. Sinus floor elevation can be performed with different surgical techniques. Crestal approach has demonstrated to be effective, less invasive, and associated w...
