Abstract

Objective: This in vitro study aimed to evaluate the effectiveness of a printed surgical guide for root sectioning in the socket-shield technique.

Materials and methods: A typodont model of the maxilla with augmented filler was used for the upper right central incisor, and CBCT images were obtained. Two types of vertical root sectioning guides were tested: one with a buccal sleeve (Group A, n = 10) and another with a buccal orientation slit (Group B, n = 10). Control group (n = 10) performed freehand cuts on printed models. After crown cutting with diamond burs, root sectioning was conducted using an ultrasonic tip with the guides. Mean and standard deviation were calculated for the remaining root length, width, and volume. Data were analyzed using the Kruskal-Wallis test and Dunn's post hoc test.

Results: Statistical analysis showed significant differences in root width between the control group (2.0 mm) and both Groups A (2.655 mm; p < 0.0001) and B (2.460 mm; p < 0.0001). Group B (5.585 mm) also showed a significant difference in root remnant compared with the control (13.880 mm; p < 0.0043). Groups A and B did not differ significantly from each other.

Conclusions: The socket shield technique is safe and effective, this study aimed to add improvements through the introduction of surgical guides, facilitating the root section, which is the critical phase so that the parameters that are requisite for success are achieved in terms of width, length, and volume of the root remnant. Both guided techniques effectively facilitated root sectioning, maintaining satisfactory root thickness and length.

Clinical significance: Sectioning the root is challenging for the correct angulation to remove the palatal portion in the socket shield technique. Therefore, modifying this technique with the use of the presented guides, it is possible to prevent damage to the soft tissues and to plan the surgery with the help of cone beam computed tomography (CBCT) scans to remove the root apex and maintain the root remnant with a thickness greater than 1.5 mm, making the socket-shield technique more predictable.

套筒屏蔽技术中牙根切片的改良手术指南--体外研究。
目的这项体外研究旨在评估印刷手术指南在窝沟封闭技术中进行牙根切片的有效性:上颌右上中切牙使用了带增量填充物的类型矫正模型,并获得了 CBCT 图像。测试了两种垂直根切引导器:一种是颊侧套筒(A组,n = 10),另一种是颊侧定向缝隙(B组,n = 10)。对照组(n = 10)在打印模型上进行徒手切割。使用金刚石车针切割牙冠后,使用带有导板的超声波刀头进行牙根切片。计算剩余牙根长度、宽度和体积的平均值和标准偏差。数据分析采用 Kruskal-Wallis 检验和 Dunn's post hoc 检验:统计分析表明,对照组(2.0 毫米)和 A 组(2.655 毫米;P)的牙根宽度存在明显差异:牙槽窝屏蔽技术安全有效,本研究旨在通过引入手术导板进行改进,促进牙根切面的切削,这是关键阶段,以便在残根的宽度、长度和体积方面达到成功的必要参数。两种引导技术都能有效促进牙根切片,保持令人满意的牙根厚度和长度:临床意义:在窝沟封闭技术中,要想以正确的角度切除腭侧部分,对牙根进行切段是一项挑战。因此,利用所介绍的导板对该技术进行改良,可以防止对软组织造成损伤,并在锥形束计算机断层扫描(CBCT)的帮助下制定手术计划,以切除牙根顶端并保持残根厚度大于 1.5 毫米,从而使牙槽骨屏蔽技术更具可预测性。
