Article Abstract
Purpose: The objective of this study was to evaluate the 5-year radiographic bone loss surrounding implants treated with surface sandblasting and acid etching (SA).
Materials And Methods: This retrospective study was conducted at a private clinic in Los Angeles, CA, USA, and included 100 patients with a total of 188 implants with an SA surface treatment. Five years after implantation, the patients were radiographically evaluated for bone loss adjacent to the implants. Each radiograph was digitized and uploaded to an online measuring instrument. Bone loss was determined by subtracting the measurements at the 5-year follow-up from the initial measurements acquired from radiographs taken at the time of implant placement. The posterior mandible, posterior maxilla, anterior mandible, and anterior maxilla received 90, 74, 6, and 18 implants, respectively.
Results: The average marginal bone vertical remodeling values on the mesial and distal surfaces of the implants were 1.19 mm and 1.25 mm, respectively, significantly lower than the 2.3-mm loss previously reported for other implants.
Conclusions: Marginal bone remodeling was visible on radiographs; however, the bone levels surrounding the implants remained essentially stable after 5 years of function.

Osteoporotic hip fractures are a considerable cause of pain and disability particularly among the elderly. Osteoporosis causes loss of bone stability, which in turn leads to an increased risk of fractures especially in metaphyseal bone. Moreover, the body's capacity for healing is diminished, resulting in prolonged recovery times following these fractures.

Gaucher's disease (GD) is the most common lysosomal storage disorder inherited in an autosomal recessive pattern. It occurs due to a deficiency of the enzyme glucocerebrosidase owing to a mutation in the acid-β-glucosidase () gene resulting in accumulation of glucocerebrosides in lysosomes of cells. It presents with abdominal distension, hepatosplenomegaly, developmental delay, pancytopenia, neurological manifestations and bone diseases.

Fahr's syndrome is a rare neurological condition marked by unusual calcifications in the basal ganglia and other brain regions, often resulting from metabolic disorders, such as hypoparathyroidism. Secondary hypoparathyroidism, a frequent complication of total thyroidectomy, can lead to Fahr's syndrome, manifesting as movement disorders, seizures, psychiatric symptoms and indications of calcium deficiency. This case report discusses a woman in her mid-30s who developed Fahr's syndrome due to secondary hypoparathyroidism after total thyroidectomy.

Fetal magnetic resonance imaging (MRI) is a safe method of in-utero evaluation of fetal anomalies and a valuable adjunct to prenatal ultrasound. The utilization of rapid sequences reduces the impact of fetal motion and allows for high contrast resolution of fetal structures. A thorough understanding of fetal anatomy and a systematic approach to MRI interpretation are essential for accurate diagnosis of fetal head and neck anomalies.

Total hip arthroplasty (THA) is the standard surgical treatment for end-stage hip osteoarthritis, with its success dependent on precise preoperative planning, which, in turn, relies on accurate three-dimensional segmentation and reconstruction of the periarticular bone of the hip joint. However, patients with hip osteoarthritis often exhibit pathological characteristics, such as joint space narrowing, femoroacetabular impingement, osteophyte formation, and joint deformity. These changes present significant challenges for traditional manual or semi-automatic segmentation methods.
