“…Hinckfuss et al [18] reported significantly less angulation error in the buccal-lingual direction for experienced operators utilizing tooth-supported surgical guides, yet no significant difference in positional errors was found between experienced and inexperienced operators. A similar result was reported by Fernandez-Gil et al in a model study using a tooth-supported guide [8]. Rungcharassaeng et al [19] used mandibular models with bilateral second premolars missing and carried out tests with the tooth-supported guide.…”

“…All the models were screened by the optical scan to make sure the difference in model surface geometry was negligible. Fernandez-Gil et al [8] examined the potential wear of the surgical guide using an optical scanner after five simulation surgeries, and no changes of the sleeves were inspected. Based on their findings, in this study, each surgical guide was used for five times only.…”

“…In the literature, the accuracy of computer-guided implant surgery had been widely examined and compared [1,5,6]. Conventionally, these studies used the method of overlapping the pre-and postoperative computed tomography (CT) images to measure the deviations of the placed implant [7,8]. The problem of this CT matching method is that the outline of the postoperative implant could be ambiguous due to the artifacts produced from the titanium implant material.…”

Studies examining the effect of operator experience on the accuracy of static guided implant surgery have used postoperative computed tomography (CT) images to measure the error, with inconsistent results. The purpose of this study was to try to clarify this issue by using a measurement method based on the postoperative optical scan. Thirty dentists were divided into an experienced group and an inexperienced group. On a partially edentulous mandibular model in the manikin head, each dentist placed three implants via the stereolithographic (SLA) surgical guide. The implant positions were identified by a desktop scanner and compared with the planned positions using a metrology software program. No statistically significant differences were observed for any of the measured positional and angular deviations of the three implant sites between experienced and inexperienced operators (p > 0.01). All the mean values of deviations of the inexperienced group, except the depth deviation, were less than the experienced group. Implants inserted by dentists under 40 years old had significantly better accuracy than senior doctors in the global deviation at implant apex (p = 0.006). Within the limits of this study, we concluded that operator experience is not a critical factor in achieving the accuracy of guided implant surgery via the tooth-supported SLA surgical guide. Large deviations could occur even with the aid of the SLA surgical guide, and care must be taken to avoid errors for both experienced and inexperienced operators.

“…Однако высказываются и другие мнения относительно точности использования таких шаблонов. Так, Á. Fernández-Gil (2017) в своей аналогичной работе in vitro указывает на возможное отсутствие клинической значимости разницы в точности между хирургами разной квалификации (0,5°), с чем нельзя согласиться, особенно учитывая все более широкое распространение скуловых и длинных имплантатов [6].…”

“…Показано, что компетенции хирурга являются большим фактором риска, нежели такие как бруксизм, курение табака, состояние кости, тип поверхности имплантата. Действительно, опытный хирург-стоматолог проводит формирование костного ложа для имплантата с меньшими угловыми отклонениями, о чем свидетельствуют результаты исследования in vitro A. Gil (2017) [6]. Применение специальных стереолитографических шаблонов облегча-ет имплантацию, делает вмешательство более точным.…”

Существует множество толкований слова «портфолио» -это прежде всего коллекция определенной области. Некоторые исследователи рассматривают портфолио как «рабочую файловую папку, содержащую многообразную информацию, которая документирует приобретенный опыт и достижения учащихся».Определение, предложенное Д. Майером: «Портфолио -это целенаправленная коллекция работ учащегося, которая демонстрирует его усилия, прогресс, достижения в одной области или более. Коллекция должна вовлекать учащегося в отбор его содержания, определения критериев его отбора; должна содержать критерии для оценивания портфолио и свидетельства о рефлексии учащегося».

Purpose To investigate the influence of different education approaches on the implantation performance (operation time, three‐dimensional deviation) of inexperienced operators. Methods Eighteen students who met the inclusion criteria were randomly assigned to traditional training group or digital training group. After training, the average operation time and implant deviation (platform deviation, apex deviation, and angle deviation) of the two groups were calculated by Student's t‐test. A self‐developed questionnaire was used to evaluate the students’ grasp of clinical knowledge and skill. Result Compared with the traditional training group, the duration of implant installation and temporary prosthesis placement of the digital training group decreased significantly (p < 0.05). The implant deviation of the digital training group was lower than that of the traditional training group. The apex deviation (p = 0.015) and angle deviation (p = 0.015) significantly improved with digital training, but differences in platform deviation (p = 0.065) were not statistically significant. The questionnaire survey showed that the overall perception of the inexperienced operators in the digital training group was better than that in the traditional training group. Conclusion In the hands of inexperienced operators, digital training reduced the operation time and improved the implant accuracy in comparison with traditional training.
