【摘要】：目的:支抗是影响正畸治疗效果的关键因素。微型种植体支抗的应用极大地拓宽了正畸治疗的范围,显著提高了正畸治疗的效果,受到广大正畸医师和患者的青睐。但微型种植体尺寸小、手术方便的同时也影响了其稳定性,脱落情况时有发生。植入部位的牙槽骨状况及手术方式是影响微型种植体稳定性的主要原因,其中牙槽骨的厚度、硬度、及种植体周围的骨量关系到种植体尺寸和形态、手术方式及载荷力值等的选择,受到大家的广泛关注。许多学者通过CT扫描研究了牙槽骨不同高度骨皮质厚度和硬度的分布规律及牙根间距离,有研究表明牙根间水平距离与骨面类型相关。大量临床试验表明以膜龈联合线作为种植体植入位点,其稳定性更高,但口腔各处膜龈联合线到牙槽嵴顶的距离不一,且具有明显的个体差异。微型种植体常用植入位置的膜龈联合线到牙槽嵴顶距离的分布情况,国内外文献未见报道。本实验通过测量微型种植体常用植入位置膜龈联合线到牙槽嵴顶的距离,探索牙龈乳头作为参考标志的可能性、膜龈联合线到牙槽嵴顶的距离的分布规律及与骨性面型的相关性,为微型种植体临床应用提供理论依据。方法:测量位置:上颌中切牙与侧切牙间(U12)、第二前磨牙和第一磨牙间(U56)、下颌中切牙与侧切牙间(L12)、第二前磨牙和第一磨牙间(L56)、第一磨牙和第二磨牙间(L67)。测量项目:牙龈乳头高度、膜龈联合线到牙槽嵴顶的距离及头颅侧位片的测量。1牙龈乳头高度(d1):牙周探针沿着远中牙龈乳头轻轻插入,有轻微阻力感后停止,然后读出牙周探针上的数据。2膜龈联合线至牙槽嵴顶的距离:2.1牙龈乳头尖至龈沟底的距离d1:同前2.2牙龈乳头尖至膜龈联合线处的距离d2:使牙周探针以牙长轴为标准,测量从牙龈乳头尖处至膜龈联合的距离。2.3附着龈宽度:牙龈乳头尖至膜龈联合线的距离减去牙龈乳头尖至龈沟底的距离即为附着龈的宽度(d2-d1)。2.4膜龈联合线至牙槽嵴顶的距离d:附着龈宽度减去2mm(生物学宽度)。公式:d(mm)=d2-d1-2mm3头颅侧位片的测量:使用Smart’n Ceph Researcher V 9.0软件(泰国清迈设计)测量每位患者的SNA、SNB、ANB角。SNA:SN与NA连线的夹角(82.8°±4.0°)SNB:SN与NB连线的夹角(80.1°±3.9°)ANB:NA与NB连线的夹角(2.7°±2.0°)结果:1各处膜龈联合线至牙槽嵴顶的距离d在左右同名牙齿间、男女之间差别无统计学意义(P0.05),因此数据合并。2牙龈乳头尖至牙槽嵴顶的距离:同名牙齿间牙龈乳头尖至牙槽嵴顶的距离在左右侧及男女间的差别无统计学意义(P0.05)。U56与U12,L12,L56,L67之间有统计学意义(P0.05),但U12,L12,L56,L67之间无统计学意义(P0.05)。3膜龈联合线处到牙槽嵴顶的距离:上颌膜龈联合处至牙槽嵴顶的距离稍大于下颌,上下颌前部膜龈联合处至牙槽嵴顶的距离分别大于后部距离。U12及U56的距离为7.3±1.2mm、6.5±1.7mm,L12、L56及L67的距离分别为5.5±1.0mm、5.0±1.2mm及4.7±1.5mm。除L56和L67之外U56,U12,L12,L56,L67两两比较均有统计学意义(P0.05)。4膜龈联合线至牙槽嵴顶的距离在不同骨性错牙合类型之间无统计学差异(P0.05)。结论:1膜龈联合线至牙槽嵴顶的距离在不同骨性错牙合面型之间差别无统计学意义。2上颌膜龈联合处至牙槽嵴顶的距离稍大于下颌,上下颌前部膜龈联合处至牙槽嵴顶的距离分别大于后部距离。
[Abstract]:Objective: anchorage is the key factor to effect the orthodontic treatment. Mini implant applications greatly broaden the scope of orthodontic treatment significantly improved the effect of orthodontic treatment, by the majority of Orthodontists and patients of all ages. But the micro implant with small size, convenient operation and also affect its stability, fall off when circumstances have occurred. The alveolar bone condition and surgical implant site is the main reason affecting the stability of Micro Implant and alveolar bone thickness, hardness, and peri implant bone to implant size and shape, operation mode and load value choice, all the attention of many scholars. Through the study on CT scanning distance distribution of different height of alveolar bone and root cortical bone thickness and hardness, studies have shown that the root between the horizontal distance and the bone surface types. A large number of clinical trials The results show that the mucogingival junction line as the implant site, the stability is higher, but the mouth throughout the mucogingival junction line to the alveolarridge distance is not the same, and has obvious individual differences. The micro implant implantation position of the mucogingival junction line to the crest of the ridge distance distribution, the domestic and foreign literature has not been reported. The experiments of measuring micro implant implantation position of mucogingival junction line to the alveolarridge distance of gingival papilla possibility as a reference marker, mucogingival junction line to the correlation distribution of alveolar ridge distance and bone surface type, and provide a theoretical basis for the clinical application of micro implant. Methods: to measure the position of the incisor and lateral maxillary incisor (U12), between the second premolar and first molar (U56), and the lateral incisor mandibular incisor (L12), between the second premolar and first molar (L56), and the first molar Two molar (L67). The measurement items: gingival papilla height, mucogingival junction line to the distance and lateral cephalometric radiographs of the alveolar crest height of gingival papilla measurement of.1 (D1): periodontal probe along the distal gingival papilla gently inserted, stop feeling after a slight resistance, and then read the data.2 mucogingiva joint line to the alveolar periodontal probe on the top of the distance: 2.1 gingival papilla tip to the sulcus at the end of the distance of d1: with 2.2 gingival papilla tip to mucogingival junction line at the distance of d2: to the periodontal probe in the long axis of the tooth as the standard, measured from the tip to the gingival papilla membrane combined with the distance.2.3 width of attached gingiva: gingival papilla tip to mucogingival junction line distance minus the papilla tip to the sulcus bottom as the distance of the width of attached gingiva (d2-d1).2.4 mucogingiva joint line to the alveolarridge distance d: width of attached gingiva minus 2mm (biological width). Formula: D (mm) = d2-d1-2mm3 cephalometric the test The amount of Smart n Ceph Researcher ": the use of V 9 Software (Thailand Chiang Mai) measurement of each patient's SNA, SNB,.SNA:SN and NA angle ANB angle line (82.8 degrees - 4 degrees) the angle between SNB:SN and NB lines (80.1 degrees - 3.9 degrees) the angle between ANB:NA and NB lines (2.7 degrees - 2 degrees results: 1) throughout the mucogingival junction line to the alveolarridge distance d between the teeth around the same, no significant difference between men and women (P0.05), so the data with.2 gingival papilla tip to the alveolarridge distance: between isonym tooth papilla tip to the alveolarridge distance on the left side and the difference between men and women there was no statistically significant difference between.U56 and U12 (P0.05), L12, L56, there was statistical significance between L67 (P0.05), but U12, L12, L56, no statistical significance between L67 (P0.05) from the.3 line at the mucogingival junction to the alveolar crest: maxillary mucogingival junction to the alveolar ridge distance slightly larger than the lower jaw, upper and lower anterior membrane The gingival and alveolar crest distance were greater than the rear distance.U12 and U56 distance was 7.3 + 1.2mm, 6.5 + 1.7mm, L12, L56 and L67 distances were 5.5 + 1.0mm, 5 + 1.2mm and 4.7 + 1.5mm. in addition to L56 and L67 U56, U12, L12, L56, L67 were 22 statistical significance (P0.05) there is no significant difference between.4 mucogingival junction line to the alveolarridge distance in different skeletal malocclusion type (P0.05). Conclusion: 1 mucogingival junction line to the alveolarridge distance in different skeletal malocclusion type had no significant difference between.2 maxillary mucogingival junction to the alveolar ridge distance is slightly larger than the upper jaw, anterior mandibular mucogingiva joint to the alveolarridge distance are larger than the rear distance.
