ISQ (RFA) vs BIC and torque: a histomorphometric and biomechanical analysis in humans.
The aim of the present study is to clarify the controversy and to demonstrate in human implants if a statistically significant correlation exists between the ISQ values and measurement of osseointegration (degree of osseointegration), the Torque-Out values and histomorphometric data of bone implant anchorage.
In the limits of the present study , this results can implicate that the development of the osseointegration after a healing period of two months, misurable through the percentage of BIC, doesn't influence the values of ISQ. The ISQ depends, also during the development of the osseointegration, strongly on the quantity of cortical bone and does not account for the osseointegration in cancellous bone, namely do not "measures" the % of osseointegration, but only the cortical anchorage. Further studies in humans implants are need to better clarify these aspects of the ISQ values.

Clinical application of bisphosphonates in implant dentistry: histomorphometric evaluation.
Bisphosphonates are pharmacologic compounds characterized by high tropism to bone tissue. They affect bone metabolism by inhibition of osteoclast recruitment, proliferation, differentiation, and function. Because they can reduce bone resorption, bisphosphonates are used mainly for the treatment of osteometabolic conditions, particularly osteoporosis, Paget disease, multiple myeloma, and other solid tumors with bone metastases. Their use has conferred great benefits to patients affected by these diseases, significantly improving their quality of life. Bisphosponates' inhibition of bone resorption might be exploited to maintain implant primary stability during the process of implant osseointegration. The aim of this histologic clinical study was to compare the response of bone tissue around an implant treated with a bisphosphonate solution (test) to that of the bone around an untreated implant (control). The bisphosphonate-treated implant showed more contact with newly formed bone than the control implant.
