目标。种植体周围组织的血管状况是牙种植体置入后健康组织建立和维持的重要参数。本研究的目的是利用犬下颌骨模型，比较皮瓣和无皮瓣种植体手术前后种植体周围粘膜的血管分布情况。研究设计。在6只杂种犬中，在下颌骨形成双侧、无牙、扁平的牙槽嵴。愈合3个月后，通过皮瓣或无皮瓣的方法在每侧放置2个种植体。在另一个3个月的愈合期后，进行活检，准备进行光镜检查，并进行形态测量。无瓣组种植体外侧的结缔组织血管丰富程度高于带瓣组。这些结果表明，无瓣手术可以增加种植体周围粘膜的血管。（口腔外科口腔医学口腔病理口腔放射学2009；107:508-512）
Objective. The vascularity of a peri-implant tissue is a very important parameter in the establishment and maintenance of healthy tissue after dental implant insertion. The purpose of this study was to compare the vascularity of the peri-implant mucosa between flap and flapless implant surgeries by using a canine mandible model.Study design. In six mongrel dogs, bilateral, edentulated, and flat alveolar ridges were created in the mandible. After 3 months of healing, 2 implants were placed in each side by either flap or flapless procedure. After another healing period of 3 months, biopsies were obtained, prepared for light microscopy, and exposed to morphometric measurements.Results. The supracrestal connective tissue lateral to the implant was found to be more richly vascularized in the flapless group than in the flap group.Conclusion. These results suggest that the flapless procedure may increase the vascularity of the peri-implant mucosa. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009; 107: 508-512)
