Abstract

Purpose

To assess the effect of scanbody (SB)-type, edentulous site, and restoration-type on the scan quality of SBs used in the treatment of short-span edentulism.

Materials and Methods

The cohort consisted of SBs with different specifications connected to bone-level implants for intraoral digitalization in the fabrication of fixed restorations. SBs matched with library CAD files for digital implant position transfer into dental CAD software were enrolled in the study group. Intraoral implant digital records were categorically evaluated to assess the quality of SB scans. In statistical analyses, the chi-squared test was used to describe the clinical variables, and logistic regression models were constructed to reveal the association between the clinical variables and SB scan quality.

Results

A total of 243 SBs were eligible for scan quality evaluation. Scan quality did not differ statistically (p > 0.05) in the SB reference area, while texture in the representation of SB was significantly affected (p < 0.05) by the variables SB-type and edentulous-site. Cylindrically designed SBs without specific geometrical features presented remarkably higher risks for reduced scan quality in SB representation.

Conclusion

SBs successfully aligned with library CAD files based on a software algorithm may not consistently present similar scan quality. Intraoral scanning of a SB is highly vulnerable with regard to scan deterioration in texture and geometry.

与CAD库匹配的植入体扫描体扫描质量的回顾性队列研究

目的评价扫描体（SB）类型、无牙位置和修复体类型对SBs治疗短牙槽位的扫描质量的影响。材料和方法该队列包括不同规格的SBs与骨水平种植体连接，用于制造固定修复体的口内数字化。将SBs与图书馆CAD文件相匹配，用于将数字种植体位置转移到牙科CAD软件中。对口腔内种植体数字记录进行分类评估，以评估SB扫描的质量。在统计分析中，采用卡方检验描述临床变量，并建立logistic回归模型揭示临床变量与脑电图扫描质量的相关性。结果243个SBs符合扫描质量评价标准。参考区域的扫描质量无统计学差异（p > 0.05），而SB类型和无牙位置变量对SB表征中的纹理有显著影响（p < 0.05）。没有特定几何特征的圆柱形SBs在SB表示中呈现出明显更高的扫描质量降低风险。结论基于软件算法的SBs与库CAD文件对齐后的扫描质量可能不一致。口腔内扫描的SB是高度脆弱的，考虑到扫描的纹理和几何恶化。

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.
