“…Schneider et al [4] report in their systematic review a mean deviation of 1.07 mm (95% CI 0.76–1.22 mm) at the shoulder and 1.63 mm (95% CI 1.26–2 mm) at the apex as well as a mean angular deviation of 5.26° (95% CI 3.94–6.58°). More recent studies report similar results [3, 6]. Thus, the accuracy of virtual implant planning in oligodontia patients is comparable to that reported in non-oligodontia cases.…”

“…The difference in position between the virtually planned and actually placed implants, according to our workflow, resembles the deviation in implant placement for virtually planned and placed implants in non-oligodontia patients [3–6]. Schneider et al [4] report in their systematic review a mean deviation of 1.07 mm (95% CI 0.76–1.22 mm) at the shoulder and 1.63 mm (95% CI 1.26–2 mm) at the apex as well as a mean angular deviation of 5.26° (95% CI 3.94–6.58°).…”

BackgroundThe aim of computer-designed surgical templates is to attain higher precision and accuracy of implant placement, particularly for compromised cases.PurposeThe purpose of this study is to show the benefit of a full three-dimensional virtual workflow to guide implant placement in oligodontia cases where treatment is challenging due compromised bone quantity and limited interdental spaces.Patient and methodsA full, digitalized workflow was performed for implant placement in two oligodontia patients. Accuracy was assessed by calculating the coordinates of the entry point (shoulder) and apex (tip) as well as the angular deviation of the planned and actual implants.ResultsImplant placement could be well performed with the developed computer-designed templates in oligodontia. Mean shoulder deviation was 1.41 mm (SD 0.55), mean apical deviation was 1.20 mm (SD 0.54) and mean angular deviation was 5.27° (SD 2.51).ConclusionApplication of computer-designed surgical templates, as described in this technical advanced article, aid in predictable implant placement in oligodontia where bone quantity is scarce and interdental spaces are limited.

“…3D models obtained from CBCT data can be accurately measured, and since they are noninvasive, they are useful in the clinical setting and for successful treatment planning [2829]. The present study demonstrated that the RSA could be measured conveniently by producing 3D models of teeth using CBCT and the Mimics software.…”

PurposeMeasurement of the root surface area (RSA) is important in periodontal treatment and for the evaluation of periodontal disease as a risk factor for systemic disease. The aim of this study was to measure the RSA at 6 mm below the cementoenamel junction (CEJ) using the Mimics software (Materialise, Leuven, Belgium).MethodsWe obtained cone-beam computed tomography (CBCT) data from 33 patients who had visited the Department of Oral and Maxillofacial Radiology of Dankook University Dental Hospital. The patients comprised 17 men and 16 women aged from 20 to 35 years, with a mean age of 24.4 years. Only morphologically intact teeth were included in our data. Because the third molars of the maxilla and mandible have a high deformation rate and were absent in some participants, they were not included in our research material.ResultsThe CBCT data were reconstructed into 3-dimensional (3D) teeth models using the Mimics software, and the RSA at 6 mm below the CEJ was separated and measured using 3-Matic (Materialise). In total, 924 3D teeth models were created, and the area at 6 mm below the CEJ could be isolated in all the models. The area at 6 mm below the CEJ was measured in all teeth from the 33 patients and compared based on sex and position (maxilla vs. mandible).ConclusionsIn this study, we demonstrated that it was feasible to generate 3D data and to evaluate RSA values using CBCT and the Mimics software. These results provide deeper insights into the relationship between periodontal inflammatory burden and systemic diseases.

“…According to these data, the simulations of maxillary resection, fibula cutting, and repositioning were accomplished. In the field of oral implantology, Shen et al (2015) presented the usage of Simplant Pro 11.04 (Dentsply) to conduct the preoperative planning including the evaluation of bone mass, the selection of suitable implant sizes, and the determination of the insertion depth and orientation [9].

Introduction: Currently, oral and maxillofacial surgery (OMFS) still poses a significant challenge for surgeons due to the anatomic complexity and limited field of view of the oral cavity. With the great development of computer technologies, he computer-aided surgery has been widely used for minimizing the risks and improving the precision of surgery.Areas covered: The major goal of this paper is to provide a comprehensive reference source of current and future development of computer-aided OMFS including surgical planning, simulation and navigation for relevant researchers.Expert commentary: Compared with the traditional OMFS, computer-aided OMFS overcomes the disadvantage that the treatment on the region of anatomically complex maxillofacial depends almost exclusively on the experience of the surgeon.
