“…For example, in [26,36], wear was evaluated relative to baseline after 6 months and 1 year, obviously having weaker variations and taking respectively the visual evaluation and the microCT as references. Time is further extended (12 and 24 months) when wear is evaluated on lithium disilicate implant crowns and their enamel antagonists, as conducted by Stück et al [21].…”

“…In other cases, specific software referring to the dental field was used, such as WearCompare (leedsdigitaldentistry.com, accessed on 20 June 2023) [63], a purpose-based software specifically produced to assess tooth wear; TRIOS Patient Monitoring (3Shape A/S, Copenhagen, Denmark), proprietary software from the same company that produces the TRIOS IOS, which allows the visual recording of changes over time; OrthoCAD (Cadent, Inc., San Jose, CA, USA), proprietary software from the same company that produces the iTero scanner, which allows the analysis of dental arch models, enabling measurements of the width of dental arches, such as in [22], where the authors evaluated the effect caused by removable appliances over a period of 10 months in children with malocclusion; and Maxilim software (V2.3.0, Medicim NV, Mechelen, Belgium), which is used to align the IOS models. Additionally, self-developed software was used to address specific needs, such as the evaluation of dental plaque in 3D models [20], the assessment of teeth [21], and the identification of structural and functional problems along with a carefully designed OCT hardware prototype [41].…”

Diagnostic Applications of Intraoral Scanners: A Systematic Review

et al. 2023

In addition to their recognized value for obtaining 3D digital dental models, intraoral scanners (IOSs) have recently been proven to be promising tools for oral health diagnostics. In this work, the most recent literature on IOSs was reviewed with a focus on their applications as detection systems of oral cavity pathologies. Those applications of IOSs falling in the general area of detection systems for oral health diagnostics (e.g., caries, dental wear, periodontal diseases, oral cancer) were included, while excluding those works mainly focused on 3D dental model reconstruction for implantology, orthodontics, or prosthodontics. Three major scientific databases, namely Scopus, PubMed, and Web of Science, were searched and explored by three independent reviewers. The synthesis and analysis of the studies was carried out by considering the type and technical features of the IOS, the study objectives, and the specific diagnostic applications. From the synthesis of the twenty-five included studies, the main diagnostic fields where IOS technology applies were highlighted, ranging from the detection of tooth wear and caries to the diagnosis of plaques, periodontal defects, and other complications. This shows how additional diagnostic information can be obtained by combining the IOS technology with other radiographic techniques. Despite some promising results, the clinical evidence regarding the use of IOSs as oral health probes is still limited, and further efforts are needed to validate the diagnostic potential of IOSs over conventional tools.

“…Innovatively, this study utilized IOS to obtain static interocclusal records of the quadrants. These records were then analyzed Recent studies have consistently shown that digital scans of the intermaxillary relationship obtained by IOSs exhibit higher precision than those achieved through conventional methods using a silicone impression material and a gypsum cast (Fraile et al, 2022;Iwauchi et al, 2022;Lee et al, 2018;Stück et al, 2022). Morsy and El Kateb (2022) assessed the precision of digital interocclusal registration compared with conventional registration in an RCT and revealed that quadrant arch interocclusal registration obtained by IOS exhibited significantly higher precision, with a mean value of 18 ± 6 μm compared with 255 ± 136 μm for conventional registration (p = .0009).…”

ObjectivesTo compare the survival and complication rates of posterior screw‐retained monolithic lithium disilicate (LS2)/veneered zirconia (ZrO2) single implant crowns (SICs), as well as analyze the occlusal changes observed during a 3‐year follow‐up period.Materials and MethodsThirty‐three patients were included and randomly divided into two groups. The test group consisted of 17 patients who received monolithic‐LS2–SIC, while the control group consisted of 16 patients who received veneered‐ZrO2‐SIC. Implant/prosthesis survival rates, technical complications, peri‐implant soft tissue conditions, and quantitative occlusal changes of SIC (obtained by the intra‐oral scanner and analyzed in reverse software Geomagic Control 2015) were assessed at 1‐ and 3‐year follow‐ups. Bone loss and Functional Implant Prosthodontic Score (FIPS) were evaluated at a 3‐year follow‐up.ResultsAfter a 3‐year follow‐up period, one patient dropped out of the follow‐up. No implant loss was observed. One crown was fractured, resulting in prosthesis survival rates of 93.75% for the monolithic group and 100% for the veneered group. A technical complication rate of 25% (4/16) was observed in the veneered group (p = .333). No significant differences in the marginal bone loss were observed at the 3‐year follow‐up (0.00 (−0.22, 0.17) mm versus 0.00 (−0.12, 0.12) mm, p = .956). The total FIPS scores for the test group were 9.0 (9.0, 9.0), while the control group received scores of 9.0 (8.0, 10.0) (p = .953). The changes in mean occlusal clearance were 0.022 ± 0.083 mm for the test and 0.034 ± 0.077 mm for the control group (at 3 years, p = .497). The changes in occlusal contact area were 1.075 ± 2.575 mm2 for the test and 1.676 ± 2.551 mm2 for the control group (at 3 years, p = .873).ConclusionAfter a 3‐year follow‐up, screw‐retained monolithic LS2 and veneered ZrO2 SIC demonstrated similar survival rates. The occlusal performance of implant prostheses needs to be closely examined during follow‐up, and appropriate occlusal adjustments need to be considered.

“…No comparison between the wear rates of the same prosthetic material supported either by teeth or by implants was performed. This study, as described by the authors themselves, was limited by the small number of cases and the large discrepancy of data related to the multitude of factors affecting tooth wear in the clinical setting [ 2 ]. A pilot in vitro study by Rosentritt et al assessed that the type of abutment (implant or natural tooth) may affect the wear of the same prosthetic material, but the possibility of drawing conclusions from the obtained data was limited [ 38 ].…”

“…Natural occlusion (i.e., the way in which the teeth of the upper and lower jaw contact each other) is a state of dynamic equilibrium and the wear of dental tissues is its inherent component [ 1 ]. Studies show that occlusion is self-adjusting through the process of wear and continuous tooth migration [ 2 ]. Under physiological conditions, tooth enamel wears off at an average rate of 30–35 µm per year [ 3 ].…”

Lithium disilicate (LDS) glass ceramics are among the most common biomaterials in conservative dentistry and prosthodontics, and their wear behavior is of paramount clinical interest. An innovative in vitro model is presented, which employs CAD/CAM technology to simulate the periodontal ligament and alveolar bone. The model aims to evaluate the effect of the abutment rigidity on the wear resistance of the LDS glass ceramic. Two experimental groups (LDS restorations supported by dental implants, named LDS-on-Implant, or by hybrid ceramic tooth replicas with artificial periodontal ligament, named LDS-on-Tooth-Replica) and a control group (LDS-Cylinders) were compared. Fifteen samples (n = 15) were fabricated for each group and subjected to testing, with LDS antagonistic cusps opposing them over 120,000 cycles using a dual axis chewing simulator. Wear resistance was analyzed by measuring the vertical wear depth (mm) and the volume loss (mm3) on each LDS sample, as well as the linear antagonist wear (mm) on LDS cusps. Mean values were calculated for LDS-Cylinders (0.186 mm, 0.322 mm3, 0.220 mm, respectively), LDS-on-Implant (0.128 mm, 0.166 mm3, 0.199 mm, respectively), and LDS-on-Tooth-Replica (0.098 mm, 0.107 mm3, 0.172 mm, respectively) and compared using one-way-ANOVA and Tukey’s tests. The level of significance was set at 0.05 in all tests. Wear facets were inspected under a scanning electron microscope. Data analysis revealed that abutment rigidity was able to significantly affect the wear pattern of LDS, which seems to be more intense on rigid implant-abutment supports compared to resilient teeth replicas with artificial periodontal ligament.
