【摘要】：[目的]评估非平台转移设计的骨水平种植系统Nobel Replace Groovy,种植修复后牙1-3年后,种植体边缘骨吸收情况,比较分析各因素对边缘骨吸收的影响。在CBCT上测量种植体周围牙槽骨和软组织的量,分析各相关性,进而验证种植体周围生物学宽度对软硬组织的彼此作用。[方法]选取2012年5月至2014年4月就诊于浙江大学医学院附属口腔医院种植中心、后牙区采用Nobel Replace Groovy种植体,行常规种植修复且修复后1-3年的患者,共69例,计131个植体。术后即刻及负载1-3年后查口腔全景片,测量种植体近远中边缘骨高度,计算边缘骨吸收量。其中55例患者,99个植体复查CBCT,分别测量颊、舌(腭)侧牙槽嵴顶到牙龈缘处牙龈的高度、牙槽嵴顶处牙龈的厚度、牙槽嵴顶下1mm、3mm、5mm处与种植体长轴垂直的牙槽骨宽度。应用SPSS17.0软件进行统计分析。[结果]口腔全景片测量Nobel Replace Groovy在后牙区近中、远中的平均边缘骨吸收量分别为(1.35±1.08)mm、(1.36±1.06)mm,种植成功疗效明确。但是,骨吸收超过2mm的分别占27.48%,23.67%。采用SPSS17.0进行统计分析,糖尿病患者和非糖尿病患者之间,厚龈型和薄龈型之间,上下颌位置、植入深度对边缘骨吸收差异有统计学意义(P0.05)。CBCT测量颊、舌(腭)侧牙槽嵴顶到牙龈缘处牙龈的高度分别为(2.62±0.71)mm、(2.69±0.78)mm,颊、舌(腭)侧牙槽嵴顶处牙龈的平均厚度分别为(2.23±0.96)mm、(2.46±1.25),采用pearson相关性分析颊龈高与颊龈厚相关,颊龈厚与牙槽嵴顶下1mm、3mm、5mm处与种植体长轴垂直的牙槽骨宽度相关。而舌侧则是两两相关。[结论]在后牙区,Nobel Replace Groovy种植体基本可以达到良好的种植效果。种植体周围的软组织一般稳定在生物学宽度范围内,软硬组织间有正相关性。
[Abstract]:[objective] to evaluate the bone resorption at the implant edge of Nobel Replace implant system, which is not designed for platform transfer, and to evaluate the bone resorption at the implant edge after 1 to 3 years of implant restoration. The effects of various factors on marginal bone resorption were compared and analyzed. The amount of alveolar bone and soft tissue around the implant was measured on CBCT, and the correlation was analyzed. [methods] from May 2012 to April 2014, the implant center of the affiliated Stomatology Hospital of Zhejiang University Medical College was selected, and the posterior region was treated with Nobel Replace Groovy implant. A total of 69 patients (131 implants) underwent routine implant repair and 1-3 years after repair. Oral panoramic films were examined immediately after operation and 1-3 years after loading to measure the bone height near the distal margin of the implant. The bone resorption was calculated in 55 patients and 99 implants. The height of the alveolar ridge from the top of the alveolar ridge to the gingival margin and the thickness of the gingival at the top of the alveolar ridge were measured. The width of alveolar bone perpendicular to the long axis of the implant at 1 mm or 3 mm below the alveolar crest was analyzed by SPSS17.0 software. [results] the Nobel Replace Groovy was measured by oral panoramic radiography in the proximal region of posterior teeth. The average marginal bone resorption was 1.35 卤1.08mm and 1.36 卤1.06mm respectively, and the successful implantation was effective. However, the proportion of bone resorption over 2mm was 27.48mm and 23.67.The SPSS17.0 was used to analyze the results of statistical analysis, and the results showed that there were two types of bone resorption between diabetic and non-diabetic patients, gingival type and thin gingival type. There were significant differences in the position of upper and lower jaw and the depth of implantation to the marginal bone resorption. CBCT was used to measure the gingival height from the top of the alveolar ridge of the lingual (palatal) side to the gingival margin. The height of the gingival was 2.62 卤0.71 mm and 2.69 卤0.78 mm, respectively. The average thickness of the gingiva at the top of the alveolar crest of the lingual (palatal) side was 2.23 卤0.96mm. the correlation between the height of buccal gingiva and the thickness of buccal and gingival was analyzed by pearson correlation. The thickness of the buccal and gingival is related to the width of alveolar bone perpendicular to the long axis of the implant at 1 mm or 3 mm below the alveolar ridge. [conclusion] in the posterior region, the Replace Replace Groovy implant can achieve good results. The soft tissue of the soft tissue is generally stable within the biological breadth, There was a positive correlation between soft and hard tissues.
