New bone formation and cancer implants; relationship to tumour proliferative activity

Breast Implants and Breast Cancer

De novo alveolar bone formation adjacent to endosseous implants.

OBJECTIVE To describe a model for the investigation of different phases of wound healing that are involved in the process resulting in osseointegration. MATERIAL AND METHODS The implants used for the study of early healing had a geometry that corresponded to that of a solid screw implant with an SLA surface configuration. A circumferential trough had been prepared within the thread region (in...

Angiogenesis and lymphangiogenesis in thyroid proliferative lesions: relationship to type and tumour behaviour.

The role of angiogenesis and lymphangiogenesis in thyroid cancer pathogenesis has not been elucidated. Patterns for tumour behaviour and metastasic spread vary according to tumour type and whether differences in the angiogenic or lymphangiogenic phenotype influence the route for tumour metastases or determine a more aggressive behaviour has not been fully explored. The angiogenic and lymphangio...

Histomorphometric evaluation of new bone formation in diabetic rats submitted to insertion of temporary implants.

This study aimed to quantify new bone formation in the femurs of diabetic Wistar rats. Over an eight-week period, MTI-MP implants were evaluated in control rats and in diabetic rats. At several points during this period, various markers for bone deposit were introduced. The material was observed under fluorescent light microscopy. New bone formation in periosteal and cortical regions linked to ...
