背景资料：在几篇文献中，我们报道了通过冠状手术入路将大鼠粘骨膜瓣抬高后3周内牙槽骨出现明显的吸收期。在本研究中，我们比较了牙槽骨的损失后粘骨膜瓣手术冠状面的方法（COR）的手术方法切割粘膜接近牙齿尖和分离的粘骨膜对牙冠（根尖的方法，AP）。方法：18只Wistar大鼠被分为2个实验组，每组由9只大鼠。在第一组中，在大鼠下颌骨右侧的颊侧和舌侧进行COR，而左侧作为假手术对照。结果：AP组牙槽骨的外侧面（颊侧或舌侧）有轻度吸收，通常发生在粘膜被切开的水平。在许多切片中，在手术切口的冠状面可见广泛的新生骨小梁。相反，冠状面手术的方法揭示了广泛的再吸收阶段，主要是牙周方面的牙槽骨。结论：本研究的结果表明，牙周手术的冠状面手术的方法刺激了一个非常具体的模式的牙槽骨的重塑爆发。
Background: In several publications, we have reported that a distinct resorptive phase of alveolar bone developed during 3 weeks following elevation of a mucoperiosteal flap in rats by a coronal surgical approach. In the present study, we compared the alveolar bone loss after mucoperiosteal flap surgery by a coronal approach (COR) to a surgical approach incising the mucosa close to the tooth apices and separating the mucoperiosteum toward the tooth crown (apical approach, AP).Methods: Eighteen Wistar rats were divided into 2 experimental groups; each group consisted of 9 rats. In the first group, COR was performed on both buccal and lingual aspects on the right side of the rat mandible, while the left side served as a sham-operated control. In the second experimental group, AP was performed.Results: In the AP group, the outer aspect (buccal or lingual) of the alveolar bone was slightly resorbed usually at the level where the mucosa was incised. In many sections, extensive modeling of new trabecular bone was seen, coronal to the surgical incision. On the contrary, the coronal surgical approach revealed an extensive resorptive phase, mainly of the periodontal aspect of the alveolar bone.Conclusions: The results of this study show that periodontal surgery by a coronal surgical approach stimulates a burst of remodeling of the alveolar bone in a very specific pattern.
