【摘要】：[目的]評估非平臺轉(zhuǎn)移設計的骨水平種植系統(tǒng)Nobel Replace Groovy,種植修復后牙1-3年后,種植體邊緣骨吸收情況,比較分析各因素對邊緣骨吸收的影響。在CBCT上測量種植體周圍牙槽骨和軟組織的量,分析各相關性,進而驗證種植體周圍生物學寬度對軟硬組織的彼此作用。[方法]選取2012年5月至2014年4月就診于浙江大學醫(yī)學院附屬口腔醫(yī)院種植中心、后牙區(qū)采用Nobel Replace Groovy種植體,行常規(guī)種植修復且修復后1-3年的患者,共69例,計131個植體。術(shù)后即刻及負載1-3年后查口腔全景片,測量種植體近遠中邊緣骨高度,計算邊緣骨吸收量。其中55例患者,99個植體復查CBCT,分別測量頰、舌(腭)側(cè)牙槽嵴頂?shù)窖例l緣處牙齦的高度、牙槽嵴頂處牙齦的厚度、牙槽嵴頂下1mm、3mm、5mm處與種植體長軸垂直的牙槽骨寬度。應用SPSS17.0軟件進行統(tǒng)計分析。[結(jié)果]口腔全景片測量Nobel Replace Groovy在后牙區(qū)近中、遠中的平均邊緣骨吸收量分別為(1.35±1.08)mm、(1.36±1.06)mm,種植成功療效明確。但是,骨吸收超過2mm的分別占27.48%,23.67%。采用SPSS17.0進行統(tǒng)計分析,糖尿病患者和非糖尿病患者之間,厚齦型和薄齦型之間,上下頜位置、植入深度對邊緣骨吸收差異有統(tǒng)計學意義(P0.05)。CBCT測量頰、舌(腭)側(cè)牙槽嵴頂?shù)窖例l緣處牙齦的高度分別為(2.62±0.71)mm、(2.69±0.78)mm,頰、舌(腭)側(cè)牙槽嵴頂處牙齦的平均厚度分別為(2.23±0.96)mm、(2.46±1.25),采用pearson相關性分析頰齦高與頰齦厚相關,頰齦厚與牙槽嵴頂下1mm、3mm、5mm處與種植體長軸垂直的牙槽骨寬度相關。而舌側(cè)則是兩兩相關。[結(jié)論]在后牙區(qū),Nobel Replace Groovy種植體基本可以達到良好的種植效果。種植體周圍的軟組織一般穩(wěn)定在生物學寬度范圍內(nèi),軟硬組織間有正相關性。
[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 鹵1.08mm and 1.36 鹵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 鹵0.71 mm and 2.69 鹵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 鹵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.
