Abstract

Purpose: This retrospective cohort study evaluated the accuracy of analog versus virtual wax-ups in prosthetic-driven planning and guided surgery.

Methods: There were 73 patients with a single missing posterior tooth who underwent either an analog or virtual wax-up design following a prosthetic-driven concept. Intraoral scans of the final restoration were performed 1 year after completion of the restoration. The accuracy was assessed by comparing the deviation between the final restoration and the wax-up (analog or virtual) of each patient at the prosthetic level. The maximum deviation in six areas (buccal top, buccal mid, buccal bottom, lingual top, lingual mid, and lingual bottom) was recorded. The accuracy was also assessed at the implant level by comparing the deviation between the virtual new implant position, which was redesigned based on the final restoration as the new wax-up, and the planned position. The mean deviations in the coronal, apical, angular, and depth measurements were recorded. A two-tailed independent t-test and a one-way analysis of variance were used.

Results: Statistically significant differences were observed between the buccal (P = 0.03) and lingual tops (P = 0.03) at the prosthetic level. Significant differences were observed in the angular (P < 0.01) and coronal (P = 0.01) deviations at the implant level. There were smaller deviations between the analog wax-ups and final restorations regardless of the prosthetic or implant level.

Conclusions: Analog wax-ups were preferable to virtual wax-ups for preoperative design in computer-guided implant surgery.

假体驱动计划和引导种植手术中模拟和虚拟上蜡的比较准确性评估：一项回顾性队列研究。

目的：本回顾性队列研究评估假体驱动计划和引导手术中模拟和虚拟蜡化的准确性。方法：73例后牙缺失患者采用假体驱动的模拟或虚拟上蜡设计。最终修复的口内扫描在修复完成1年后进行。通过比较最终修复和每个患者在假体水平的蜡化（模拟或虚拟）之间的偏差来评估准确性。记录颊上、颊中、颊下、舌上、舌中、舌下6个区域的最大偏差。通过比较虚拟新种植体位置与计划位置之间的偏差，在种植体水平上评估准确性，虚拟新种植体位置是根据最终修复作为新上蜡而重新设计的。记录冠状、根尖、角度和深度测量的平均偏差。采用双尾独立t检验和单因素方差分析。结果：在假体水平上，颊部（P = 0.03）与舌部（P = 0.03）差异有统计学意义。种植体水平的角度偏差（P < 0.01）和冠状偏差（P = 0.01）差异有统计学意义。无论假体或种植体水平如何，模拟上蜡和最终修复体之间的偏差较小。结论：在计算机引导下种植手术的术前设计中，模拟打蜡术优于虚拟打蜡术。

期刊介绍： Journal of Prosthodontic Research is published 4 times annually, in January, April, July, and October, under supervision by the Editorial Board of Japan Prosthodontic Society, which selects all materials submitted for publication. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. The Journal will cover all diagnostic and clinical management aspects necessary to reestablish subjective and objective harmonious oral aesthetics and function. The most-targeted topics: 1) Clinical Epidemiology and Prosthodontics 2) Fixed/Removable Prosthodontics 3) Oral Implantology 4) Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology) 5) Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism) 6) Orofacial Pain and Temporomandibular Disorders (TMDs) 7) Adhesive Dentistry / Dental Materials / Aesthetic Dentistry 8) Maxillofacial Prosthodontics and Dysphagia Rehabilitation 9) Digital Dentistry Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, of orofacial trauma, or of a variety of dental and oral diseases and orofacial pain conditions. Reviews, Original articles, technical procedure and case reports can be submitted. Letters to the Editor commenting on papers or any aspect of Journal of Prosthodontic Research are welcomed.
