Abstract

Introduction

The primary objective was to assess 1-year clinical and radiographic outcomes of a newly designed implant with a machined long neck in the anterior region, including marginal bone loss, horizontal bone width, vertical bone height, and implant survival and success rates. The secondary objective was to evaluate the effect of guided bone regeneration on bone dimensional changes and implant survival and success rates.

Materials and Methods

A total of 117 implants in 58 patients who received the novel implant in the anterior region were included. Marginal bone loss, horizontal bone width, and vertical bone height changes were assessed using panoramic radiographs and cone beam computed tomography (CBCT) scans obtained after prosthetic restoration and at the one-year follow-up. Implant survival and success rates, along with the influence of guided bone regeneration (GBR) on bone dimensional changes, were statistically analyzed.

Results

Within the one-year follow-up period, implant survival and success rates were 97.43% and 91.45% at the implant level, and 94.83% and 82.76% at the patient level, respectively. Among the 114 surviving implants, the mean marginal bone loss was 0.46 ± 1.05 mm. In the subset of 32 implants with available CBCT data, horizontal bone width and vertical bone height changes were minimal in both buccal and palatal/lingual aspects. Subgroup analyses indicated that guided bone regeneration provided measurable advantages in preserving bone dimensions at specific sites, particularly in the mid-buccal region and the palatal/lingual vertical height. However, at most other reference points, dimensional changes were comparable irrespective of whether GBR was performed.

Conclusion

A novel implant featuring a machined long neck exhibited clinically acceptable outcomes with respect to implant survival, implant success, and bone dimensional stability over a one-year follow-up period.

一种新型机械长颈种植体的生存和影像学结果：1年回顾性研究。

前言：主要目的是评估新设计的前区机械长颈种植体1年的临床和影像学结果，包括边缘骨丢失、水平骨宽度、垂直骨高度、种植体存活率和成功率。次要目的是评估引导骨再生对骨尺寸变化、种植体存活和成功率的影响。材料与方法：58例患者，共117颗种植体在前牙区种植。使用全景x线片和锥形束计算机断层扫描（CBCT）评估假体修复后和一年随访后的边缘骨丢失、水平骨宽度和垂直骨高度变化。统计分析种植体成活率、成功率以及引导骨再生（GBR）对骨尺寸变化的影响。结果：随访1年，种植体成活率97.43%，种植体成活率91.45%，患者成活率94.83%，患者成活率82.76%。在存活的114个种植体中，平均边缘骨损失为0.46±1.05 mm。在32个有CBCT数据的种植体中，水平骨宽度和垂直骨高度的变化在颊和腭/舌方面都是最小的。亚组分析表明，引导骨再生在保留特定部位的骨尺寸方面具有可测量的优势，特别是在中颊区和腭/舌垂直高度。然而，在大多数其他参考点，无论是否进行GBR，尺寸变化都是可比性的。结论：在一年的随访期间，一种新型的长颈机械假体在种植体存活、种植体成功和骨尺寸稳定性方面表现出临床可接受的结果。

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.
