Accuracy of Two Stereolithographic Surgical Templates: A Retrospective Study

Abstract

The results of the present study indicated best accuracy of the single-type guide using a bone or tooth support. The multiple-type guide recorded the best accuracy data when the mucosa support was considered comparing either a fixed and a not-fixed single-type guide.

A Novel Dental Implant Guided Surgery Based on Integration of Surgical Template and Augmented Reality

“…The entry point and apical mean deviations as well as angle, lateral, and depth deviations obtained from this study were within the lower end of the comparison ranges. The deviations may be related to mechanical errors caused by the gap between the guiding sleeve and the bur during simulation procedures . Comparing previous results listed in Table with the data attained from this study, we conclude that computer‐aided positioning of oral implants with an HMD and a computer‐generated AR environment as well as a SLA surgical template exceeds presently available methods in accuracy.…”

How Accurate Is CBCT in Measuring Bone Density? A Comparative CBCT‐CT In Vitro Study

“…3,5,6,[10][11][12][13] With CT, bone density measurements are given in HU based on density values for air (-1,000 HU) and pure water (0 HU). 3,5,6,[10][11][12][13] With CT, bone density measurements are given in HU based on density values for air (-1,000 HU) and pure water (0 HU).…”

“…4 Several studies have proposed a variety of methods for assessing bone density, but these involve evaluation either at the time of implant site preparation or subsequent to implant placement. 3,5,6 Even more recently, due to the need for less expensive image acquisition protocols or for scanners with lower radiation dose, cone beam CT (CBCT) has been widely employed for oral and maxillofacial imaging, 7 as it seems to provide good spatial resolution, gray density range, and contrast, as well as a good pixel/noise ratio. 3,5,6 Even more recently, due to the need for less expensive image acquisition protocols or for scanners with lower radiation dose, cone beam CT (CBCT) has been widely employed for oral and maxillofacial imaging, 7 as it seems to provide good spatial resolution, gray density range, and contrast, as well as a good pixel/noise ratio.…”

The influence of guided sleeve height, drilling distance, and drilling key length on the accuracy of static Computer‐Assisted Implant Surgery

“…As the popularity of the sCAIS increases, the responsible introduction of it's broad application requires a knowledge of common variables and decision‐making points during treatment planning and execution. Errors during data acquisition, data transfer, data processing, treatment planning, guide design and production, as well as surgical execution might all contribute to increased deviations from the virtually planned implant position . The variables encountered during the treatment‐planning step by itself are numerous.…”
