“…In another in vitro study, the marginal discrepancy for definitive single‐unit iFDPs, where the prostheses were cemented to standardized titanium abutments, was investigated using stereomicroscopy (Donmez & Okutan, 2022). For the fabrication of the SM iFDPs, three different definitive restorative materials were used, including two composites and one resin‐modified ceramic material.…”

“…When it comes to definitive iFDPs, the present review found conflicting results on the marginal and internal discrepancies between AM and SM fabrication methods. Whereas some results favored the SM method (Revilla‐Leon, Methani, et al, 2020), another study showed significantly lower marginal discrepancies for the AM fabricated prostheses (Donmez & Okutan, 2022). The differences in outcomes might be attributed to the use of different restorative materials and manufacturing technologies.…”

AimTo compare and report on the performance of implant‐supported fixed dental prostheses (iFDPs) fabricated using additive (AM) or subtractive (SM) manufacturing.MethodsAn electronic search was conducted (Medline, Embase, Cochrane Central, Epistemonikos, clinical trials registries) with a focused PICO question: In partially edentulous patients with missing single (or multiple) teeth undergoing dental implant therapy (P), do AM iFDPs (I) compared to SM iFDPs (C) result in improved clinical performance (O)? Included were studies comparing AM to SM iFDPs (randomized clinical trials, prospective/retrospective clinical studies, case series, in vitro studies).ResultsOf 2′184 citations, no clinical study met the inclusion criteria, whereas six in vitro studies proved to be eligible. Due to the lack of clinical studies and considerable heterogeneity across the studies, no meta‐analysis could be performed. AM iFDPs were made of zirconia and polymers. For SM iFDPs, zirconia, lithium disilicate, resin‐modified ceramics and different types of polymer‐based materials were used. Performance was evaluated by assessing marginal and internal discrepancies and mechanical properties (fracture loads, bending moments). Three of the included studies examined the marginal and internal discrepancies of interim or definitive iFDPs, while four examined mechanical properties. Based on marginal and internal discrepancies as well as the mechanical properties of AM and SM iFDPs, the studies revealed inconclusive results.ConclusionDespite the development of AM and the comprehensive search, there is very limited data available on the performance of AM iFDPs and their comparison to SM techniques. Therefore, the clinical performance of iFDPs by AM remains to be elucidated.

“…17 Composite resins are among the materials that can be additively manufactured. [18][19][20][21][22] Recently, additively manufactured composite resins that contain ceramic particles have been marketed as definitive restorative materials.

ObjectiveThe purpose of this in vitro study was to evaluate the effect of potassium aluminum sulfate (alum) application on the stainability and translucency of computer‐aided design and computer‐aided manufacturing (CAD‐CAM) materials after coffee thermocycling (CTC).Materials and MethodsDisk‐shaped specimens (Ø10 × 1 mm; N = 200) were fabricated by using additively (Crowntec [CT] and Varseo Smile Crown Plus [VS]) and subtractively manufactured (Brilliant Crios [RCR], CEREC Block [FC], and Vita Enamic [VE]) CAD‐CAM materials and polished. All specimens were randomly divided into two groups as alum applied and control (n = 10). All specimens were then subjected to CTC (10,000 cycles at 5–55°C) and color coordinates were measured at each time interval. Color differences (ΔE00) and relative translucency parameters (RTPs) were calculated and the data were statistically analyzed (a = 0.05).ResultsAmong tested time intervals, alum applied specimens had their lowest ΔE00 after alum application (p ≤ 0.006), except for FC (p = 0.177). In addition, alum applied RCR had lower ΔE00 values than its control specimens (p = 0.029). Alum applied specimens had their lowest RTP after CTC (p < 0.001) and alum application decreased the RTP of CT (p = 0.010). CTC reduced the RTP of all materials in control groups (p < 0.001). Alum applied CT had higher RTP than its control specimens (p = 0.049).ConclusionsAlum application's effect on color change varied depending on the material and alum mostly resulted in clinically acceptable changes in translucency. CTC led to unacceptable color and translucency changes based on previously reported threshold values.Clinical SignificanceOptical properties of CAD‐CAM materials and the sustainability of these properties over time is critical for longevity. Alum may improve the color stability of reinforced composite resin when subjected to long‐term coffee consumption.
