Objective To evaluate the method, clinical effects and influential factors of using three dimensional external fixators in the treatment of severe open comminuted tibiofibular fractures 5 cm near the knee or ankle joints. Methods We retrospectively analyzed 32 cases of open comminuted tibiofibular fracture 5 cm near the knee (11 cases) or ankle joints (21 cases). They were treated with three dimensional external fixators from October 2000 to May 2005. The patients with small wounds were treated with manipulative reduction or leverage reduction through the wound under the guidance of C-arm radiography. In case of malreduction or soft tissue being tangled by the fracture ends, visible reduction was carried out after the wound was lengthened or a small incision was added. Limited internal fixation was used in case of necessity. The results were evaluated in terms of shortening of the fractured limbs, X-ray manifestation, bilateral flexion differences and postoperative walking complaints. Results Follow-ups from 5 to 18 months (nine months on average) showed that all the cases achieved osseous union. The mean union time was 5.6 months. The total excellent and good rates of fracture healing and functional recovery were 81.3% and 87.5% respectively. Conclusion Application of the three dimensional external fixator is appropriate for the treatment of severe open comminuted tibiofibular fracture 5 cm near the knee or ankle joints, because its operative procedure is simple, the injury it causes is minimal, its fixation is reliable and its complications are quite limited.

Objective To investigate the clinic application of micro-implant anchorage in the treatment of maxil-lary protrusion malocclusion. Methods Twenty-two patients,aged 18 to 25 years old,with maxillary protrusion were divid-ed into two groups:experimental group and control group with 11 patients in each group. All patients were treated with ex-traction. Micro-screw palatal implant was used in the cases of experimental group as orthodontic anchorage ,and traditional anchorage composed of extraoral arch used in the cases of control. The cephalometric films were measured before and after treatment. Statistical methods were utilized to analyze the morphological changes of facial profile and hard tissues in both groups. Results The values of U1-NA(mm:3.08±1.18 vs 8.15±3.05) and U1-SN(101.90°±3.50° vs 117.90°±6.05°) were sig-nificantly decreased after treatment compared with those before treatment in the experimental group ( P<0.01). The value of U1-L1(123.98°±5.78°vs 103.89°±8.95°) was significantly increased after treatment (P<0.01). In control group, the values of U1-NA (mm:5.01±1.34 vs 9.12±2.13) and U1-SN(101.90°±3.97° vs 114.87°±7.69°)were significantly decreased after treat-ment. The values of U1-L1(126.01°±3.12°vs 112.98°±5.98°) and U6-PtPNS(mm:21.45±2.43 vs 18.36±2.19)were significant-ly increased after treatment (P<0.05). The value of U1-L1(19.48°±8.90° vs 13.01°±5.90°) was significantly changed in exper-imental group than that of control group, but the value of U6-PtPNS(mm:0.90±0.29 vs 3.78±0.12)was significantly changed in control than that of experimental group (P<0.01). Conclusion The maxillary protrusion malocclusion with micro-im-plant anchorage can be used as treatment for patients with maxillary protrusion that needs strong anchorage.

Objective To evaluate the orthodontic effect of surgery on mixed dentition period class Ⅲ malocclusion and to investigate the effective therapeutic method of the skeletal class Ⅲ malocclusion.Methods A total of 20 patients aged 8.5 to 9.1 years with early mixed dentition class Ⅲ skeletal malocclusion.The treatment was divided into two phases.During the first phase,the entire stuffy group was treated with a bonded maxillary expansion and protraction.During the second phase,the entire study group received multiple loop edgewise arch wire (MEAW) treatment until an ideal occlusion relationship achieved.Comparison of the pre-and post-orthodontic treatment cephalometric radiographs had been done after maxillary protraction and MEAW were applied for patients.Results In the 20 patients after orthodontic treatment,Class Ⅲ skeletal facial profile was improved,the retraction of anterior teeth was obvious,and there were significant changes in dentition; the profile of soft tissue and satisfactory occlusion relationship were significantly improved,as compared with the changes between pre-treatment and post-treatment.Conclusions Skeletal Ⅲ malocclusion in early mixed dentition can be successfully treated.The results can be satisfied with improved class Ⅲ skeletal and molar relationship,high-angle and profile of soft tissue.

BACKGROUND:Studies addressing reconstruction of tooth tissue engineering have shown that tooth structure can be constructed using tissue engineering technology. Tooth root and its periodontal attachment are critical for tooth survival and functions, based on which, whether we can target root tissues with simple structure for tissue engineering construction by bypassing a complex dental tissue engineering concept with the structural integrity?
OBJECTIVE:To construct a tissue-engineered dental root by seeding dental papil a cells, as seed cells, into poly(lactic-co-glycolic acid)/sodium alginate hydrogel.
METHODS:Rabbit dental papil a cells were isolated and cultured. The cells were then mixed with 1%sodium alginate hydrogel at a final density of 6×109/L. The cellsuspension was seeded into a poly(lactic-co-glycolic acid) scaffold with predetermined shape of human tooth and solidified with calcium chloride. Final y, the cel-scaffold composites were subcutaneously implanted into the back of nude mice. The specimens were harvested after 4 and 8 weeks respectively and processed for gross inspection, X-ray and CT examination and histological observation.
RESULTS AND CONCLUSION:The newly formed tissue kept the original shape of human dental root 4 and 8 weeks post-implantation. After 4 weeks of implantation, the specimen density was low;the root implants appeared to be incompletely mineralized, alginate hydrogels were degraded, but the copolymer scaffold was not degraded;a number of dentin-like structure appeared, and a fibrous membrane structure was visible on the surface of specimens paral el to the root surface, but the structure was not continuous, and no pulp cavity formed. After 8 weeks, the newly formed tissue was highly mineralized close to root tissue of the nature tooth;the copolymer scaffold was mostly degraded;specimens appeared to have a large number of mature dentin-like structure, and form continuous fibers membrane on the surface paral el to the root surface, below which, cementum-like structure formed. Artificial dental root with biological y similar structures of human dental roots can be constructed using the method of tissue engineering.
