BACKGROUND: Mini-screw anchorage is an innovation technique applied in the orthodontic field, expanding the treatment ability of orthodontic appliance. Accurate of mini-screw insertion in the target position is a clinical problem which making orthodontist trouble in this technique application. OBJECTIVE: To introduce a kind of three dimensional guide of mini-screw used as anchorage in orthodontic treatment and to evaluate the positioning accuracy. DESIGN, TIME AND SE'I-rlNG: A contrast study was performed at the Department of Orthodontics, Capital Medical University from April to October 2005. PARTICIPANTS: Twenty cases (40 mini-screws) of maxillary critical anchorage requisition were considered as the experimental group, and 15 cases (30 mini-screws) who were not treated with surgical guide were considered as the control group. METHODS: Self-made stent was used as a positioning guide for implantation of mini-screw anchorage between the roots of upper second bicuspid and first molar. Thereafter, the position was measured. MAIN OUTCOME MEASURES: The vertical distance from measure points to the reference middle line were measured. RESULTS: In 40 mini-screws inserted with the aid of surgical guide, the average survival time of mini-screw as anchorage was 10.3 months, 2 were lost, and the success rate was 95%. The average survival time of 30 mini-screws in the control group was 9 months, 9 were loss, and the success rate was 70%. The positioning measurement showed that deviation of mini-screw was not found in the experimental group, but it was found in the control group. CONCLUSION: By aid of surgical guide splint, mini-scraw can be inserted correctly into the target region.

ObjectiveTo evaluate and compare the prognosis of idiopathic macular holes (IMH) and traumatic macular holes (TMH) treated by pars plana vitrectomy (PPV). Methods The clinical data of 72 IMH eyes and 55 TMH eyes, which were treated by PPV between November 2001 and December 2007,were retrospectively reviewed. The visual outcomes and macular anatomic closure were evaluated, and their relationships with prognostic factors including the size of macular hole (MH), preoperative visual acuity (VA) and duration of disease were analyzed. Results The closure rate of IMH (100. 0%) was significant higher than that of TMH (85.5%) (P=0. 001). The postoperative VA of IMH and TMH were (0. 25±0.02) and (0. 21±0. 21) respectively, both significantly increased compare to their preoperative VA (t=-6. 841, -4. 093; P=0.000). VA-increased IMH and TMH eyes had same VA (χ2=3. 651, P=0.07).Pre-PPV VA≥0. 1 IMH eyes had better outcomes than Pre-PPV VA＜0. 1 IMH eyes (χ2 = 12.04, P=0. 001), while Pre-PPV VA had no effects on TMH outcomes (χ2=0. 371, P=0. 486). IMH eyes with small holes had better outcomes (t=2. 476, P=0. 016), and TMH eyes with small holes had better closure (t= -4. 042, P＜0. 001). The duration of disease had no significant influence on TMH visual (χ2=0. 704,P = 0. 401 ) and anatomic (χ2 = 0. 166, P= 0. 684) outcomes. Conclusions PPV is an effective treatment for MH. The closure rate of IMH is higher than that of TMH. The diameter of MH and preoperative VA are major factors for IMH outcomes, and the duration of disease and preoperative VA have no effects on postoperative VA in TMH.
