目的：评价改良骨劈开术后唇腭侧骨壁吸收的临床效果。方法：选取上颌前牙缺失、牙槽嵴高度足够、宽度为3~5 mm的患者20例，采用骨劈开术同期植入28颗种植体，填骨粉，覆盖生物膜。将28个牙位按随机数字表法分为对照组和观察组，每组14个牙位。对照组劈开位置为唇腭侧骨板中间，观察组对劈开位置进行改良，劈开位置为唇腭侧骨板中间位置偏腭侧1 mm。6个月后行二期手术，翻瓣观察种植体周围骨质愈合情况，计算出种植体唇腭侧骨壁高度吸收值。结果：观察组种植体唇侧骨壁有（0.77±0.11）mm吸收，腭侧骨壁有（0.41±0.12）mm吸收；对照组分别有（1.57±0.16）mm、（0.34±0.11）mm吸收。两组唇侧骨壁吸收比较差异有统计学意义（P<0.05），腭侧骨壁吸收比较差异无统计学意义（P>0.05）。结论：改良骨劈开术在唇侧骨壁保留了相对多的骨松质，有效防止唇侧骨壁的进一步吸收。
目的：評價改良骨劈開術後脣腭側骨壁吸收的臨床效果。方法：選取上頜前牙缺失、牙槽嵴高度足夠、寬度為3~5 mm的患者20例，採用骨劈開術同期植入28顆種植體，填骨粉，覆蓋生物膜。將28箇牙位按隨機數字錶法分為對照組和觀察組，每組14箇牙位。對照組劈開位置為脣腭側骨闆中間，觀察組對劈開位置進行改良，劈開位置為脣腭側骨闆中間位置偏腭側1 mm。6箇月後行二期手術，翻瓣觀察種植體週圍骨質愈閤情況，計算齣種植體脣腭側骨壁高度吸收值。結果：觀察組種植體脣側骨壁有（0.77±0.11）mm吸收，腭側骨壁有（0.41±0.12）mm吸收；對照組分彆有（1.57±0.16）mm、（0.34±0.11）mm吸收。兩組脣側骨壁吸收比較差異有統計學意義（P<0.05），腭側骨壁吸收比較差異無統計學意義（P>0.05）。結論：改良骨劈開術在脣側骨壁保留瞭相對多的骨鬆質，有效防止脣側骨壁的進一步吸收。

Objective:To evaluate the clinical treatment effects of the absorption of buccal and palatal bone-wall by improved bone splitting technique.Method:20 patients with missing maxillary anterior teeth,the sufficient vertical bone height and the maxillary anterior alveolar ridge of 3-5 mm were enrolled in this study. 28 implants were placed using bone splitting technique ,bone substitute grafting and guide bone regeneration technique would be used. 28 implants were randomly divided into the observation group and the control group,each group had 14 dental implants. The bone split position in the control group was in the middle of the lip side and palatal side,while the bone split position in the observation group was 1 mm by palatal side. Two-stage operations were after 6 months,the bone of implants around and caculating the loss of bone wall height were observed.Result:The absorption of buccal bone wall was(0.77±0.11)mm and the absorption of palatal bone wall was(0.41±0.12)mm in the observation group. The absorption of buccal bone wall was(1.57±0.16)mm and the absorption of palatal bone wall was(0.34±0.11)mm in the control group. The difference of absorption in buccal bone wall between the two groups was statistically significant(P<0.05).The difference of absorption in palatal bone wall between the two groups was not statistically significant(P>0.05).Conclusion:The split buccal bone wall retained relatively more cancellous bone in the improved bone splitting technique,that effectively prevented further absorption of buccal bone wall.
