摘要
背景：上颌咬合平面的确定是无牙颌患者治疗中的一个重大临床挑战，同时也是有牙患者复杂全口重建的关键，包括那些接受种植体支持修复的患者。目的：这项临床研究使用数字三维分析评估了上颌牙体与面部地标的矢状位置关系，并评估了在无牙颌患者中使用模拟福克斯平面板（也称为咬合平面引导板）的适宜性和可靠性：根据特定的纳入标准，在德国法兰克福歌德大学修复牙科系招募了 81 名受试者。使用 GOM Inspect Pro 软件（GOM，德国布伦瑞克）获取口内和面部扫描结果并进行分析。测量了上颌咬合平面与坎珀平面和腭嵴线各三个变体之间的角度，分别与上、中、下腭嵴点有关。然后将这些修改后的平面与模拟数字福克斯平面板建立的平面进行比较，该平面与上颌前牙和两个象限后牙的最低点相适应：本研究共评估了 81 名受试者（58 名女性和 23 名男性），他们的平均年龄为 23.9 岁。上颌咬合面的角度与上康氏面、中康氏面或上腭嵴线的角度相比没有发现明显的角度差异（P>0.05）。右侧（3.443°）和左侧（3.535°）康帕上平面与上颌咬合平面之间的角度最小。70% 的患者在使用 Fox 平面板后会出现两个不同的咬合平面，与数字确定的平面有明显偏差（p 结论：Fox 平面板与数字确定的咬合平面有明显偏差：上、中Camper平面以及上ala-ragus线可视为近似平行的参考平面，适用于修复治疗中上颌咬合平面的常规确定。然而，与数字评估方法相比，在牙质较好的患者中应用福克斯平面板的变异性很大，这表明由于其在上颌牙体上的定位不明确，其可重复性很低。临床试验注册网站：https://drks.de/search/de/trial/DRKS00030166。
3D evaluation of sagittal inclination of the maxillary dentition in relation to facial landmarks: A cohort study
Background
The determination of the maxillary occlusal plane presents a significant clinical challenge in the treatment of edentulous patients as well as it is critical for complex full-mouth reconstructions in dentate patients, including those with implant-supported rehabilitations. While the use of a Fox plane plate is standard in edentulous cases, its application in dentate patients lacks thorough documentation in existing literature.
Purpose
This clinical study assessed the sagittal position of the maxillary dentition in relation to facial landmarks using a digital three-dimensional analysis and evaluated the suitability and reliability of applying a simulated Fox plane plate, also known as an occlusal plane guide, in dentate patients.
Materials and Methods
Eighty-one subjects were recruited at the Department of Prosthetic Dentistry of Goethe University Frankfurt, Germany, according to specific inclusion criteria. Intraoral and facial scans were obtained and analyzed using GOM Inspect Pro software (GOM, Braunschweig, Germany). The angles between the maxillary occlusal plane and three variations each of Camper's plane and ala-tragus line, relating to superior, middle, and inferior tragus points, were measured. These modified planes were then compared to a plane established by a simulated digital Fox plane plate, which was adapted to the maxillary anterior teeth and the lowest point of the posterior teeth in both quadrants.
Results
A total of 81 subjects (58 female and 23 male) with a mean age of 23.9 years were evaluated in this study. No significant angular difference was found between the angles of the maxillary occlusal plane compared with superior Camper's plane, middle Camper's plane, or superior ala-tragus line (p >0.05). The smallest angle occurred between superior Camper's plane and the maxillary occlusal plane on both the right (3.443°) and left (3.535°) sides. The application of a Fox plane plate resulted in two different occlusal planes in 70% of patients, significantly deviating from the digitally determined plane (p <0.05).
Conclusion
Superior and middle Camper's planes, along with superior ala-tragus line, can be considered approximately parallel reference planes and are suitable for routine determining of the maxillary occlusal plane in restorative treatments. However, in contrast to digital evaluation methods, the application of a Fox plane plate in dentate patients showed high variability, indicating its low reproducibility due to its ambiguous positioning on the maxillary dentition.
期刊介绍：
The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal.
The range of topics covered by the journals will include but be not limited to:
New scientific developments relating to bone
Implant surfaces and their relationship to the surrounding tissues
Computer aided implant designs
Computer aided prosthetic designs
Immediate implant loading
Immediate implant placement
Materials relating to bone induction and conduction
New surgical methods relating to implant placement
New materials and methods relating to implant restorations
Methods for determining implant stability
A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
