“…Another strength of this study is characterized by the fact that only a small number of articles [17,46] have used marginal bone loss in maxilla as a term of comparison between a fully digital versus conventional approach and both studies reported in accordance with this present prospective study an implant success rate of 100% and no statistically prosthesis survival differences between the 2 groups.…”

Background: The objective of this study was to compare conventional versus digital impressions for Full-Arch maxillary rehabilitations. Methods: Patients selected for this study were treated with full-arch screw-retained rehabilitations supported by six immediately loaded dental implants. Patients have been scheduled randomly into control (conventional impression group, CIG) and test (digital impression group, DIG) groups respectively for a fully conventional workflow and a fully digital workflow. In both groups, within 24 h, temporary prostheses were delivered. Four months after the implant positioning, the two groups dealt with the fabrication of definitive restorations: conventional pick-up was performed in the control group, and definitive digital impressions were carried out in the test group. The time involved following these two procedures was recorded. Patients underwent intraoral digital radiographs to evaluate the accuracy of the framework-implant connection, check for the presence of voids at the bar-implant connection and measure bone level. Criteria used to assess success at the prosthetic level were the occurrence of prosthetic maintenance, the absence of fractures of the acrylic resin superstructure and voids. Results: A total of 50 patients received immediately loaded prostheses supported by six implants (total 300 implants). A fixture and prosthetic survival rate of 100% was observed. All digital X-ray examinations revealed a bar-implant connection accuracy and no voids. Differences that were not statistically significant (p > 0.05) in marginal bone loss were found between control and test groups. Significantly less time was spent to perform digital impression procedure (p < 0.05). Conclusions: Clinical and radiological results of the test group advocate a satisfactory accuracy and predictability of the intraoral scanner (IOS) to be a reliable alternative in clinical practice for implant full-arch rehabilitations and suggest fabrication of definitive restorations with a successful marginal fit precision.

“…Several studies have investigated the accuracy of full‐arch digital implant scans. Most of them are in vitro and have shown that digital scans demonstrate comparable accuracy to that of conventional impressions 17‐29 . Additionally, there is a paucity of data in regards to three‐dimensional (3D) printed casts generated from Standard Tesselation Language (STL) files (digital scans) 30 .…”

Purpose: A prospective clinical study to compare for the first time the accuracy of digital and conventional maxillary implant impressions for completely edentulous patients. Materials and Methods: Sixteen patients received maxillary implant supported fixed complete dentures. After the verification of the conventional final casts, the casts were scanned with a desktop (extraoral) scanner. Intraoral full-arch digital scans were also obtained with scan bodies and STL files. Extraoral and intraoral scans were superimposed and analyzed with reverse engineering software. The primary outcome measure was the assessment of accuracy between scans of the verified conventional casts and digital full-arch impressions. The secondary outcome was the effect of the implant number on the 3D accuracy of impressions with Spearman's rank correlation coefficient. Results: The 3D deviations between virtual casts from intraoral full-arch digital scans and digitized final stone casts generated from conventional implant impressions were found to be 162 ± 77 µm. In the 4-implant group, 5-implant group, and 6-implant group the 3D deviations were found to be 139 ± 56 µm, 146 ± 90 µm, and 185 ± 81 µm, respectively. There was a positive correlation between increased implant number and 3D-deviations, but there was no statistically significant difference (p = 0.191). Conclusions: The 3D accuracy of full-arch digital implant scans lies within previously reported clinically acceptable threshold. Full-arch digital scans and a complete digital workflow in the fabrication of maxillary fixed complete dentures may be clinically feasible.

“…For digital scanning of implants, two approaches have been proposed: confocal microscopy (IOS) and stereo photogrammetry. 36 Both systems were studied in short-term clinical trials, with similar results: a satisfactory survival rate after 1 to 2 years, as well as clinical and radiological responsiveness of the artificial frames [59,60]. Several in vitro investigations compared the accuracy of digital scanning for distance and angulation to traditional impressions, and current IOS offered superior or equal findings.…”

Total edentulism is a serious public health issue, particularly among the aged people. Edentulism has a detrimental impact on various elements of a patient's everyday life, including masticatory function, phonetics, and facial structure, with significant psychosocial implications. For those patients, complete dentures remain the first option. Despite the fact that age-specific rates of edentulism are expected to decline, demand for complete dentures will continue to rise in the next decades. Patients with new complete dentures who are edentulous are fairly pleased, however up to 30% of them have issues. They continue to struggle with issues such as unattractive appearance, ripping pain or discomfort owing to the failure of holding and stabilization, impaired articulation, food deposition under the denture, and trouble with chewing. These types of issues can lower one's quality of life and force him to seek additional help to resolve them. In some circumstances, a specific clinical technique known as rebasing is recommended as a solution to these issues.
