研究目的:

动态导航技术是常用于辅助种植体植入的数字化技术之一,其精确度显著高于自由手植入。动态导航的精确植入依赖于患者三维CBCT影像与颌骨实际位置的配准。目前最常见的配准方式是基于咬合夹板的有标记点配准(如“U”型管配准),通过使用阻射点进行配准。然而,这种配准方式需要提前制作“U”型管并佩戴后再次拍摄CBCT,程序繁琐。并且该方式还存在复位误差、不易长期储存、影响标定装置安装等缺点,限制了动态导航技术在临床上的高效应用。“牙尖比对”技术是通过直接使用牙尖作为配准点的无标记点配准方法,不需要使用额外的辅助装置,极大程度简化了临床流程。因此,本研究拟对比上颌前牙区单颗或多颗牙缺失患者使用数字化动态导航“牙尖比对”配准技术与常规“U”型管配准技术在辅助牙科种植体植入的三维精确度,临床效率和后期修复效果,评估该新配准技术的临床有效性。同时记录术中不良事件以及以患者为中心的结果,从而评估其安全性。  

Objectives of Study:

Dynamic navigation is one of the digital techniques commonly used to assist accurate implant placement. Its accuracy is proved to be significantly higher than that of free-hand implant placement. The Accuracy of dynamic navigation-assisted implant placement depends heavily on the registration procedure between the patient's 3D CBCT images and the actual position of the jaw. Currently, the most common registration method is based on splints with marked points (such as the U-shaped tube-based registration), which functions through the radiopaque markers on the splints. However, this registration method requires preparation of the U-shaped tube in advance and taking CBCT again with it, which is very tedious. Moreover, this method is also subjected to shortcomings such as repositioning error, difficulty in long-term storage, and occupying dentition space against the installation of the calibration device, which all limit its clinical efficiency. In contrast, the tooth cusp-based registration is a marker-free method that directly uses the tooth cusp as the registration marker, and does not require additional auxiliary devices, which simplifies the clinical procedures. Therefore, this study intends to compare the tooth cusp-based registration with the conventional U-shaped tube-based registration for their three-dimensional accuracy, clinical efficiency and restoration effect in dynamic navigation-assisted dental implant placement for patients with single or multiple maxillary anterior tooth loss. Intraoperative adverse events and patient-reported outcomes will also be recorded to assess the safety of these two methods.

药物成份或治疗方案详述:

拍摄初诊开口位CBCT确定需要在导航下进行种植体植入的患者签署知情同意后,根据纳入排除条件进行筛选。筛选入组的患者使用随机数表的方法进行随机入组。所有患者预先扫描数字化口腔印模记录咬合关系。对于“U”型管组的患者,使用硅橡胶和“U”型管制作患者个性化“U”型管,患者佩戴“U”型管拍摄CBCT。而牙尖比对组患者不做其它操作。随后,研究团队根据CBCT和数字化口腔印模资料对患者进行术前设计。手术方案与患者沟通同意后进行导航手术,所有植入流程均为常规手术流程,术中记录手术和配准时长。种植体植入后,旋入覆盖螺丝或愈合基台,术后拍摄CBCT。愈合3~4个月,旋入覆盖螺丝的患者进行二期手术。二期手术后3周,患者进行取模,制作修复体,常规戴牙。 

Description for medicine or protocol of treatment in detail:

Open-mouth CBCT was taken at first visit to evaluate if the surgery needs the assistance of dynamic navigation. Patients who need dynamic navigation-assisted surgery will be screened according to the inclusion and exclusion criteria after signing the informed consent. The enrolled patients will be randomly divided into the experimental and control group using random number table. The occlusion of all patients will be recorded using digital oral scan. For patients enrolled in the U-shaped tube group, personalized U-shaped tube will be prepared using silicone rubber and "U" tube, and then the patients will take CBCT wearing the U tube. In contrast, no additional procedures will be done for patients in the tooth cusp-based registration group. Then, the research team will perform preoperative design based on the CBCT and the digital oral impression data. After the surgical plans are communicated and finalized with the patients, navigation-assisted surgery will be carried out. All the surgeries will be performed according to the routine protocols, and the operation and registration time will be recorded. After implant insertion, screws or healing abutments will be installed, and postoperative CBCT will be taken. After 3 to 4 months of healing, the patients with cover screws will undergo the second-stage surgery. Three weeks after the second-stage surgery, impression will be recorded to make the temporary or final prosthesis.

随机方法(请说明由何人用什么方法产生随机序列):

患者签署知情同意书后,由资料管理员通过随机数表生成随机数,若为奇数,则纳入牙尖比对组;若为偶数,则纳入“U”型管组。

Randomization Procedure (please state who generates the random number sequence and by what method):

After the patient has signed the informed consent form, the data manager of the research team will generate a random number through the random number table. If the number is odd, the patient will be included in the tooth cusp-based registration group.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

盲法:

由于受试者需要配合完成“U”型管制作过程且术中患者保持清醒,因此该临床试验无法实现对患者和术者进行盲法。但本研究中数据分析人员无法得知患者的具体分组,患者姓名将使用无法识别分组的患者编号替代,以减少偏倚。

Blinding:

This trial cannot be blinded for patients and dentists who perform the surgery because subjects have to cooperate to prepare the U-shaped tube and patients will remain awake during the operation.But the data analysts will not be informed of the specific group of the patients to reduce the risk of bias, and patients' names will be replaced by the patients' ID that cannot identify the group.
