Do comparative study between conventional en-masse retraction ( sliding mechanics ) and en-masse retraction using orthodontic micro implant?
Mini-implants provided absolute anchorage in patients requiring maximum anterior retraction. No differences in the mean retraction time were noted between 2 groups.
Non-curative gastrectomy does not improve survival in patients with metastatic gastric cancer, nor reduces the rate of late occlusions. There is no need for prophylactic palliative gastrectomy in patients with gastric cancer who do not have bleeding or obstruction preoperatively. Among those patients, postoperative chemotherapy seems to improve survival.
