Background: The immediate loading of implants with a porous anodized surface is a well‐described technique. Few data are however available on the long‐term outcomes. Purpose: The aim of this prospective study was to assess the 10‐year performance of TiUnite implants supporting fixed prostheses placed with an immediate loading approach in both postextractive and healed sites. Materials and Methods: All patients received a fixed provisional restoration supported by immediately loaded parallel design, self‐tapping implants with a porous anodized TiUnite surface, and an external‐hexagonal connection. Both healed and postextractive cases were included. Success and survival rate for restorations and implants, changes in marginal peri‐implant bone level, probing depth measurements, biological or technical complications, and any other adverse event were recorded at yearly follow‐up up to 10 years after surgery. Results: A total of 210 implants fulfilled the inclusion criteria and were consecutively placed in 59 patients. Forty‐seven (22.38%) implants were lost because of the recalled patient refused to attend the planned 10‐year follow‐up. Five over 210 (2.38%) implants were lost. At the final follow‐up, the accumulated mean marginal bone loss and probing depth were, respectively, 1.93 mm (SD 0.40) and 2.54 mm (SD 0.44) for the implants placed in healed sites (n = 84); 1.98 mm (SD 0.37) and 2.63 mm (SD 0.39) for the implants placed in postextractive sites (n = 74). The restorations examined achieved a cumulative 65.26% success rate and 97.96% survival rate. The implants placed in healed and postextractive sites, respectively, achieved a 98.05% and a 96.52% cumulative survival rate. Conclusions: Positive results in terms of bone maintenance in the long‐term perspective are to be expected using immediately loaded implants with a TiUnite porous anodized surface in both postextractive and healed sites when adequate levels of oral hygiene are kept.  相似文献

Intrasellar cysticercosis   总被引:1,自引:0,他引:1  
Eight patients with cysticerci located inside the sella turcica are presented, and the clinical and radiological features of this rare form of neurocysticercosis are discussed. Clinical features included nonspecific ophthalmological and endocrinological disturbances similar to those produced by other sellar lesions. Computerized tomography (CT) usually showed a hypodense mass that simulated either a cystic tumor or an arachnoid cyst. Cerebrospinal fluid (CSF) findings were also nonspecific, as immunological reactions to cysticercosis were most often negative when inflammation was limited to suprasellar and intrasellar regions. An incorrect diagnosis of tumor was frequent in these cases. In contrast, when intrasellar cysticercosis was associated with other forms of neurocysticercosis, proper integration of CT and CSF data permitted an accurate diagnosis. Cysticercosis should be suspected in patients with hypodense juxtasellar lesions living in geographical areas where this disease is endemic. Prompt surgical resection of cysticerci will avoid irreversible damage to visual function.  相似文献

The pulmonary circulation represents a unique vascular bed, receiving 100% of the cardiac output while maintaining low blood pressure. Multiple different cell types, including endothelium, smooth muscle, and fibroblasts, contribute to normal vascular function, and to the vascular response to injury. Our understanding of the basic cell biology of these various cell types, and the roles they play in vascular homeostasis and disease, remains quite limited despite several decades of study. Recent advances in approaches that enable the mapping of cell origin and the study of the molecular basis of structure and function have resulted in a rapid accumulation of new information that is essential to vascular biology. A recent National Institutes of Health workshop was held to discuss emerging concepts in lung vascular biology. The findings of this workshop are summarized in this article.  相似文献
