Development and application of venous thromboembolism intelligent evaluation and automatic warning system / 医疗卫生装备

Objective To develop an intelligent evaluation and automatic warning system to improve the diagnosis rate of venous thrombo embolism (VTE) and strengthen its standardized treatment.Methods A clinical data center was constructed by using data extraction,conversion and loading,which involved in military medical system,clinical laboratory system,electronic medical record system and surgical anesthesia system.The warning model was established with international standards,clinician experiences,warning parameters selection by statistical method and weighted assignment.Results The system could predict the risk of the hospitalized patient for VTE rapidly and inform the doctor in time.Conclusion The system facilitates the doctor to prevent and control VTE,and thus is worthy promoting practically.

Effects of alveolar bone resorption on stress of tooth/implant-supported restoration connected by precision attachment / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To investigate the effects of alveolar bone resorption on stress of tooth/implant-supported restoration connected by precision attachment using three-dimensional finite element(FEM) approach.</p><p><b>METHODS</b>The FEM was applied to analyze the stress distribution of tooth/implant-supported restoration connected by precision attachment under various loading conditions when the alveolar bone was absorbed to different level.</p><p><b>RESULTS</b>The stress values of the tooth, implant and their surrounding bone increased when their surrounding bone decreased by bone absorption.</p><p><b>CONCLUSION</b>The stress values of the tooth, implant and their surrounding bone were closely related with the bone resorption.</p>

Clinical analysis of immediate implant and implant-supported complete denture for 12 patients with severe periodontitis / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To evaluate clinical results of implant-supported complete denture of 12 patients with severe chronic periodontitis.</p><p><b>METHODS</b>After systematically periodontic treatment and controlling the inflammation, 12 cases with severe chronic periodontitis were extracted the residual teeth and received immediate implant placement. The implant-supported complete dentures were finished at 5 or 6 months after operation. Restorative results were evaluated with clinical examination, radiological examination and chief complaints of the patients.</p><p><b>RESULTS</b>A total of 108 implants were placed into 20 dental arches, including 37 immediate implants. Average loading was for 3 years and all implants were stable. Progressive bone resorption was observed around two implants. The average bone resorption of other peri-implants was (1.33 +/- 0.10) mm. The implant survival rate was 98.1%. The immediate implant survival rate was 97.3%.</p><p><b>CONCLUSIONS</b>After periodontic treatment, the patients with severe chronic periodontitis could be restored using immediate implant placement and implant-supported complete denture. It can shorten the treatment period, reduce absorption of alveolar and obtain a favorable result by oral health care.</p>

Affecting factors for height of adjacent gingival papilla of maxillary central incisor single implant / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To analyze and find factors affecting the height of adjacent gingival papilla of maxillary central incisor single implant in human in order to promote the esthetic result of dental implants.</p><p><b>METHODS</b>Sixteen maxillary central incisor single implants of 16 patients and 30 sites of adjacent tissues and prosthesis were evaluated. Data on the height of adjacent gingival papilla of dental implant and relative factors were obtained from clinical parameters, photographs, research models, and X radiographs.</p><p><b>RESULTS</b>The mean and standard deviation of adjacent gingival papilla height of maxillary central incisor single implant were (4.01 +/- 1.85) mm. Statistical analysis revealed that factors affecting the height of adjacent gingival papilla of implant were as following from strong to weak: vertical distance between contact point and gingival margin, vertical distance between proximal bone level of natural tooth and implant abutment, vertical distance between proximal bone level of natural tooth and contact point, proximal protruding degree of crown, horizontal distance between abutment and root, length ratio of the crown and fixture, vertical distance between proximal bone level of implant and abutment, lip-side protruding degree of crown, probing depth.</p><p><b>CONCLUSIONS</b>Multiple factors affected the height of adjacent gingival papilla of maxillary central incisor single implant in human.</p>

Clinical study on the stability of palatal implant anchorage / 中华口腔医学杂志

<p><b>OBJECTIVE</b>To evaluate the clinical stability of the palatal implant anchorage system in orthodontic treatment.</p><p><b>METHODS</b>Sixteen osseointegrated implants (5.0 mm in diameter, 6 mm length) were inserted in the median palatal suture area of 19 patients with malocclusion (average age: 18.22 +/- 7.10 years, from 11 years to 35 years 1 month) as anchorage of active orthodontic treatment with MBT appliance. The standard lateral cephalogram after implant placement and before implant removing was taken to compare the radiological parameters.</p><p><b>RESULTS</b>The successful rate of palatal implant anchorage was 84.2%. The average duration of 16 palatal implant was 23.08 +/- 8.06 months (from 10 months to 36 months). There were no statistical differences in all parameters from the implant placement to the end of treatment. IL-X was from (62.88 +/- 5.85) mm to (62.45 +/- 6.70) mm, IL-Y was from (36.66 +/- 5.41) mm to (37.96 +/- 4.90) mm, IAP-PP was from (73.81 +/- 8.84) degrees to (74.72 +/- 9.22) degrees, IAP-Y was from (62.09 +/- 9.33) degrees to (63.85 +/- 10.96) degrees, U6-Y is from (20.80 +/- 5.87) mm to (21.49 +/- 6.00) mm.</p><p><b>CONCLUSIONS</b>Stable palatal implant anchorage was maintained during active orthodontic treatment.</p>
