ABSTRACT
Objective To analyze the effect of one-part form mini-implant in treatment of immediately and delayed repair of edentulous space. Methods Retrospectively analyzed 80 cases of edentulous space patients in our hospital from Jan. 2009 to Jan. 2011, and divided them into the immediately repair group ( observation group) and the delayed repair group ( control group) according to time of edentulous space repair. Patients of the two groups were given permanent PFM 3 months later, and regular clinical and X-ray examinations were made to evaluated clinical efficacy and complications of the two groups. Results The score of ISQ of the observation group was higher than that in the control group with significant difference (P <0. 05); and the postoperative complications of the observation group was significantly decreased compared to the control group with a significant difference (P <0. 05). Conclusion Mini-implant used in immediately repair in edentulous space can remove pain in a short time with less postoperative complications, it has more advantages than delayed repair of edentulous space.
ABSTRACT
The incidence of traumatic rupture of the tracheobronchial tree has been increased considerably with advent of widespread mechanization and high speed era. Rupture of the bronchus is an unusual result of nonpenetrating trauma to chest. Early diagnosis and primary repair not only restore normal lung function but also avoid difficulties and complications associated with delayed diagnosis and repair. These complications are pneumonia, atelectasis and lung abscess secondary to the bronchial obtruction. We experienced a case of partial rupture on left main bronchus caused by nonpenetrating blunt chest trauma with rib fractures 1 year ago. He was suffered from progressively developing dyspnea on exercise and treated as bronchial asthma at other hospital. Bronchoscopic finding was the narrowed lumen of left main bronchus at 1cm from carina by web-like membrane. We confirmed by bronchogram and repaired by end to end anastomosis, which is rare delayed finding in bronchial rupture without pulmonary complications. We report a case of nonpenetrating traumatic bronchial rupture, manifested by bronchial web in bronchoscopy.
