The aim of this cross-sectional prospective study was to evaluate the bone density changes around the bicortical corticobasal implant placed in the maxilla over 18 months of follow-up using cone-beam computed tomography (CBCT), focusing on the comparison between the anterior and posterior teeth and regions.
Thirty-five subjects (20, 53.26%, were males, and 15, 46.73%, were females) received 380 implants (Basal Cortical Screwable implant, BCS®) at Narsinhbhai Patel Dental College and Hospital, India. Implant survival and success were assessed using Albrektsson criteria for implant success. The peri-implant bone density values were measured using CBCT (Vatech PaX-i 3d Smart) and software (Anatomage, San Jose, California, USA) at the baseline (immediate postoperative) and at the 18-month follow-up visit. For standardization purposes, the bone density values for only the maxillary implants were measured at the level of the second implant thread in four sites: buccal, mesial, distal, and palatal, respectively. The recorded data were tabulated and grouped according to the tooth's region (anterior/posterior) and sites (mesial, distal, buccal, and palatal).
The implant's survival rate was 100%. After 18 months, the bone density increased significantly ( < 0.05) in all the sites in both anterior and posterior regions. The study's findings revealed a higher bone density increase in the posterior region compared to the anterior region after 18 months of follow-up, except for the palatal site.
Within the limitations of this study, an increase in the peri-implant bone density has been associated with the use of corticobasal implants over time, with reported anterior/posterior regional variations.
This study provides valuable insights into the bone density changes associated with bicortical corticobasal implants and emphasizes the importance of CBCT in evaluating bone density, as well as the significance of regional considerations in implant dentistry. By integrating these findings into clinical practice, clinicians can improve treatment outcomes and ensure long-term implant survival.

本横断面前瞻性研究的目的是使用锥形束计算机断层扫描（CBCT）评估在上颌植入双皮质皮质骨基台种植体后18个月的骨密度变化，重点是前牙区和后牙区及区域之间的比较。
35名受试者（20名男性，占53.26%；15名女性，占46.73%）在印度纳辛哈伊·帕特尔牙科学院和医院接受了380颗种植体（皮质骨可旋入式种植体，BCS®）。使用阿尔布雷克特松种植成功标准评估种植体的存活率和成功率。在基线（术后即刻）和18个月随访时，使用CBCT（Vatech PaX-i 3d Smart）和软件（美国加利福尼亚州圣何塞的Anatomage）测量种植体周围骨密度值。为了标准化，仅在上颌种植体的四个部位（颊侧、近中、远中、腭侧）的第二个种植体螺纹水平测量骨密度值。记录的数据根据牙齿区域（前牙/后牙）和部位（近中、远中、颊侧、腭侧）进行列表和分组。
种植体存活率为100%。18个月后，前牙区和后牙区所有部位的骨密度均显著增加（<0.05）。研究结果显示，随访18个月后，除腭侧部位外，后牙区的骨密度增加高于前牙区。
在本研究的局限性内，随着时间的推移，种植体周围骨密度的增加与皮质骨基台种植体的使用有关，且存在前/后区域差异。
本研究为双皮质皮质骨基台种植体相关的骨密度变化提供了有价值的见解，强调了CBCT在评估骨密度方面的重要性，以及在种植牙科中区域考虑的意义。通过将这些发现纳入临床实践，临床医生可以改善治疗效果并确保种植体的长期存活。如何引用本文：多希A，帕特尔J，高尔V，上颌弓双皮质锚定皮质骨基台种植体植入后种植体周围骨密度的评估：一项横断面前瞻性研究。《当代牙科实践杂志》2024；25（9）：820 - 829。
