Experience introduction of induced eruption on multiple adjacent impacted teeth in anterior maxillary bone / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To study the method of induced eruption on multiple adjacent impacted teeth in anterior maxillary bone.</p><p><b>METHODS</b>Twenty-two multiple adjacent impacted teeth of 9 cases were chosen. The position of the impacted teeth and the relationship to each other were assessed on X-ray images, oral examination and plaster model. The impacted teeth were extracted or induced erupted with the closed-eruption technique and fixed orthodontic appliances.</p><p><b>RESULTS</b>Of 22 impacted teeth, 19 impacted teeth were moved into arches by induced eruption with the closed-eruption technique and fixed orthodontic appliances. There were not root adsorption or conglutination for 19 impacted teeth. Three impacted teeth with deformed root were extracted. The average time for treatment was 19 months.</p><p><b>CONCLUSION</b>With correct diagnosis, reasonable design, the complicated impacted teeth could be moved into alignment with good esthetic and functional effect.</p>

<p><b>OBJECTIVE</b>To observe and compare the curative effect of pingyangmycin and sodium morrhuae respectively in the treatment of oral and maxillofacial venous malformation.</p><p><b>METHODS</b>Forty cases of oral and maxillofacial venous malformation were induced in this study, 20 of which were given local injection of low dose of pingyangmycin, and 20 given local injection of 5% sodium morrheate. The therapeutic effects were observed.</p><p><b>RESULTS</b>The effective cases of pingyangmycin was 19, and the effective cases of sodium morrhuate was 12. The side effect was found in 10 cases of, and in 15 cases sodium morrhuate group, the former was mainly pingymangmycin group systemic, the later was mainly local. The difference was significant between the two groups (P < 0.05).</p><p><b>CONCLUSIONS</b>Pingyangmycin is more effective in effective rate and side effect treatment of venous hemangioma than sodium morrhuate.</p>
