【摘要】：目的探究?jī)煞N骨粉對(duì)少數(shù)民族老年患者牙槽窩保存的臨床效果。方法 40例老年拔牙患者隨機(jī)分為兩組,每組20例。對(duì)照組應(yīng)用進(jìn)口骨粉,觀察組應(yīng)用國(guó)產(chǎn)骨粉作為骨移植材料進(jìn)行拔牙窩保存術(shù),并在3個(gè)月內(nèi)觀察測(cè)量牙槽嵴吸收情況。結(jié)果兩組患者治療前后牙槽嵴高度差異明顯(P0.05);隨著時(shí)間延長(zhǎng),兩組患者牙槽嵴高度均有所降低,但觀察組患者降低程度明顯大于對(duì)照組(P0.05)。兩組患者治療前后牙槽嵴寬度差異明顯(P0.05);隨著時(shí)間延長(zhǎng),兩組患者牙槽嵴寬度均有所降低,但觀察組患者寬度降低程度明顯大于對(duì)照組(P0.05)。兩組患者治療前后牙槽嵴灰度差異明顯(P0.05);隨著時(shí)間延長(zhǎng),兩組患者牙槽嵴灰度均有所降低,但觀察組患者灰度降低程度明顯大于對(duì)照組(P0.05)。結(jié)論國(guó)產(chǎn)骨粉在拔牙后牙槽骨保存術(shù)中效果與進(jìn)口骨粉具有一定差異,但其效果良好,在經(jīng)濟(jì)欠發(fā)達(dá)的地區(qū)仍然具有良好的應(yīng)用前景。
[Abstract]:Objective to investigate the clinical effect of two kinds of bone powder on alveolar fossa preservation in elderly minority patients. Methods 40 elderly patients with tooth extraction were randomly divided into two groups, 20 cases in each group. The imported bone powder was used in the control group and the bone powder made in China was used as the bone graft material in the observation group for the preservation of extraction of tooth nest and the absorption of alveolar ridge was observed and measured within 3 months. Results the alveolar ridge height of the two groups was significantly different before and after treatment, and the alveolar ridge height of the two groups decreased with time, but the degree of reduction in the observation group was significantly higher than that in the control group. The width of alveolar ridge was significantly different between the two groups before and after treatment, but the width of alveolar ridge in the observation group was significantly higher than that in the control group. The gray scale of alveolar ridge in the two groups was significantly different before and after treatment, and decreased with time, but the gray level of the patients in the observation group was significantly higher than that in the control group (P 0.05). Conclusion the effect of domestic bone powder in alveolar bone preservation after extraction is different from that of imported bone powder, but its effect is good, and it still has a good application prospect in economically underdeveloped areas.
