Bone-Implant Interface Around Titanium Implants Under Different Loading Conditions: A Histomorphometrical Analysis in the Macaca fascicularis Monkey

Bone-implant interface around titanium implants under different loading conditions: a histomorphometrical analysis in the Macaca fascicularis monkey.

BACKGROUND Bone healing around endosseous dental implants is associated with peri-implant loading conditions. Therefore, the aim of this study was to evaluate histomorphometrically the bone response around unloaded, delayed, and immediately loaded implants with a progressive thread design that were placed in the posterior regions of the lower jaw in monkeys. METHODS Nine adult monkeys (Macaca...

Astrocytoma in a cynomolgus monkey (Macaca fascicularis).

concurrent infection with Torulopsis glabrata in a dog. Predisposing factors included a history of chronic skin disease of obscure origin treated with antibiotics and/or corticosteroids for 6 months. Laboratory findings, sebaceous gland atrophy, epidermal atrophy, and epidermal hyperkeratosis were all findings that were consistent with those of corticosteroid effects. The immune status of this ...

Porencephaly in a Cynomolgus Monkey (Macaca Fascicularis)

Porencephaly was observed in a female cynomolgus monkey (Macaca fascicularis) aged 5 years and 7 months. The cerebral hemisphere exhibited diffuse brownish excavation with partial defects of the full thickness of the hemispheric wall, and it constituted open channels between the lateral ventricular system and arachnoid space. In addition, the bilateral occipital lobe was slightly atrophied. His...

Finite Element Analysis of Different Hip Implant Designs along with Femur under Static Loading Conditions

Background: The hip joint is the largest joint after the knee, which gives stability to the whole human structure. The hip joint consists of a femoral head which articulates with the acetabulum. Due to age and wear between the joints, these joints need to be replaced with implants which can function just as a natural joint. Since the early 19th century, the hip joint arthroplasty has evolved, a...
