“…On the other hand, a surgical template in SCAI limits the operator’s perceptive feedback, without any possibility of correction of the established plan and to change the implant dimension in the operative phase. The IOS’s use speeds up the treatment timing, eliminating intermediate manual phases and patient discomfort for a conventional impression [ 38 ]. This is particularly true using a scanner not needing the powder for the occlusal surfaces’ record as employed herein.…”

“…Even in this phase, the practitioner experience seems to play a decisive role in the impression-making process’s precision and duration. Regarding accuracy, it has not been still demonstrated the superiority of the digital approach compared to the conventional one [ 38 ]; indeed, Mangano et al found quite heterogeneous outcomes using twelve different IOS machines taking an impression of six implants inserted in totally edentulous upper arches [ 21 ]. Hence, some doubts persist on the IOS’s reliability, particularly when long span prosthesis is going to be realized.…”

A full-arch rehabilitation of the edentulous upper jaw without grafting procedures exploits the residual alveolar or the basal bone, with the necessity of long implants placed with a particular orientation. The precision in planning and placing the fixtures is fundamental to avoid clinical problems and to allow an acceptable connection with the prosthesis. The computer-aided implantology resulted in more accuracy than the traditional one, with a high standard of correspondence between the virtual project and the real outcome. This paper reports about the two different digital protocols, static and dynamic, as support to implant-borne prosthetic rehabilitation of edentulous maxillae. Two pterygoid and two/four anterior standard implants were seated in both cases by two different operators, without flap raising, and immediately loaded. This approach avoided the posterior cantilever by-passing the maxillary sinus and was adequately planned and realized without any surgical or prosthetic error. The two digital flow-charts were described step by step, underlining each other’s advantages and drawbacks compared to a free-hand approach.

“…[19][20][21] Other studies reported no significant difference. 22,23 Moreover, the technique for obtaining the virtual model either by direct intraoral scanning or via cast digitization influenced the marginal fit of single crowns. 24 There is lack of literature on the comparative evaluation of the fit of the endocrowns fabricated by different techniques and workflow.…”

Objective To compare the marginal and internal adaptation of endocrowns produced using conventional technique, digital technique, and combination (cast digitization) techniques using microcomputed tomography (micro‐CT). Materials and Methods Ten freshly extracted human mandibular molar teeth were prepared for all‐ceramic endocrowns. A total of 40 Lithium Disilicate (IPS e.max) endocrowns were fabricated and grouped according to the impression and production technique to four groups: Group (CO): Conventional impression/heat pressed endocrowns (n = 10), Group (CAD): Direct scanning of teeth/CAD‐CAM endocrowns (n = 10), Group (COMIO): Combination; Cast digitization using Intraoral scanner/CAD‐CAM endocrowns (n = 10), Group (COML): Combination; Cast digitization using laboratory scanner/CAD‐CAM endocrowns (n = 10). Micro‐computed tomography was used to measure the marginal and internal gaps in 11 predetermined sites. Mean marginal and internal gaps were compared using analysis of variance and Scheffe's post hoc test. Results CO, CAD, COMIO, and COML groups showed significant differences in the mean marginal gap (150 ± 35 μm, 120 ± 27 μm, 110 ± 24 μm, 120 ± 29 μm, respectively p = 0.013), gap at line angle (280 ± 70 μm, 130 ± 37 μm, 140 ± 54 μm, 130 ± 33 μm, respectively, p < 0.001), gap at cavity wall (210 ± 76 μm, 140 ± 43 μm, 140 ± 52 μm, 150 ± 44 μm, respectively, p = 0.010) and gap at pulpal floor (500 ± 150 μm, 240 ± 58 μm, 260 ± 59 μm, 240 ± 64 μm, respectively, p < 0.001). Conclusion Digitally fabricated endocrowns showed superior marginal and internal fit compared to the conventionally fabricated endocrowns. Clinical Significance Marginal and internal adaptation are detrimental factors for the success and survival of dental restorations including endocrowns. When compared with the conventional impressions and conventional production techniques, Digital workflow is more predictable and reliable as it reduces errors and improves the accuracy of fit.

“…Intraoral scanners (IOSs) are widely used by clinicians in the daily practice as an alternative to conventional impressions in fixed prosthodontics 5‐9 . IOSs may provide numerous advantages over conventional physical impressions, including better patient acceptance, greater standardization of the impressions, instant evaluation of the digital model, and no need of physical casts 10‐17 . Moreover, it has been shown that digital scans are a trustworthy option to conventional impression making for unitary and short‐span fixed dental prostheses 18,19 .…”

Objective To provide a comprehensive protocol for final impressions making under rubber dam isolation by using an intraoral scanner. Clinical consideration Impression making after tooth preparation with rubber dam isolation are impossible with conventional physical impressions, which are not with intraoral scanners. Digital technologies have disrupted dentistry in the last decades, bringing new, straightforward, and more time‐efficient protocols for dental practice. Conclusions Taking in consideration the beneficial properties of scanning under rubber dam this protocol can be highly recommended for everyday use for making definitive intraoral scans for tooth‐supported restorations. Clinical significance The described protocol offers the possibility to make a final impression in a stress‐free environment, without blood or saliva, to obtain a better visualization and scanning of the finish line, and the potential of save time on definitive impression making.
