“…Considering that regardless of the design, all prostheses seated on the inserted implants, it can be stated that fabrication of interim prosthesis prior to sCAIS implant placement is feasible. [3][4][5][6]9 However, for all the variables, the errors of the different groups were measurable, and some designs and workflows had more superior seating than others. Specifically, PF interim prostheses for intraoral cementation following surgery appears to have a more superior seating, especially with larger internal spacing.…”

“…Immediate implant restoration by interim prosthesis has significant benefits, such as immediate aesthetic and functional restorations, reduction of treatment duration, modeling of peri-implant soft tissue and development of emergence profile for definitive implant prosthesis. [1][2][3][4][5][6] However, fabricating a satisfactory interim prosthesis immediately following implant placement is time-consuming, technique sensitive, and may require an additional clinical visit. 1,2 Therefore, there is a consistent need for a reliable, simple, and efficient approach to fabricate implant immediate interim prosthesis.…”

BackgroundImmediate implant restoration by prefabricated prosthesis has multiple benefits. However, the design and insertion workflow of the prosthesis may influence the seating.PurposeEvaluation of seating accuracy of prefabricated interim prosthesis of different designs and insertion workflows for immediate restoration of implants placed via static computer‐assisted implant surgery (sCAIS).Materials and MethodsA maxillary model without incisors was used to plan for two implants at the lateral incisor locations. According to the planned implants, sCAIS surgical template and a four‐unit interim prosthesis were designed. Four prostheses were fabricated based on the design and insertion workflow. The first prosthesis involved complete fabrication (CF) of the interim prosthesis, where the interim prosthesis is fabricated for laboratory attachment to abutments. The other three prostheses were produced by partial fabrication (PF), where the interim prosthesis shell was produced with internal spacing between the fitting surface and the abutments. The PF prostheses were cemented on abutments attached to the inserted implants. Three different PF prosthesis designs were included with different levels of internal spacing: 100 μm (PF.1), 200 μm (PF.2), and 300 μm (PF.3). A total of 15 surgical models received implants on which each prosthesis was seated and scanned by a laboratory scanner. The vertical, horizontal, and proximal contact errors were measured.ResultsAlthough all prostheses were seated on every model, the CF prostheses had greater vertical error, followed by PF.1, PF.2, and PF.3 prostheses, respectively. A similar pattern was observed for proximal contact error, where PF.3 was most superior. PF.3 prostheses had the least horizontal error than the other prostheses.ConclusionsAll interim prostheses experienced errors at the vertical, horizontal, and proximal surfaces, which can be attributed to deviations of the inserted implants. The PF of interim prosthesis with increased internal spacing for intraoral insertion appeared to reduce seating errors.

“…The use of non‐engaging conical abutments for bridge prosthesis and the application of the recommended manufacturer torque might have ensured complete seating on the implants via deformation of the prosthesis, which was noticed from resistance to the tightening of the retaining screws. Since all the prostheses were eventually seated on the implants, it can be assumed that this clinical protocol is feasible (Lanis et al., 2019; Leite et al., 2020; Schubert et al., 2019; Venezia et al., 2019). However, the study revealed that all the prostheses were associated with measurable errors in the vertical position and proximal contact regions that may have a clinical impact.…”

“…Today, it is feasible to combine the sCAIS with digital prosthesis fabrication in a single workflow to immediately load the implants. In this workflow, the prosthesis is fabricated according to the digital implant planning prior to the actual implant placement (Lanis et al., 2019; Leite et al., 2020; Venezia et al., 2019). Subsequently, at the time of implant surgery, the implants are placed via sCAIS, followed by immediate restoration by the premade digital prosthesis (Johansson et al., 2009; Komiyama et al., 2008).…”

Objectives Evaluation of seating accuracy of implant immediate provisional prostheses fabricated prior to fully guided static computer‐assisted implant surgery (sCAIS). Materials and Methods Two maxillary training models were used to plan for single anterior (S‐Ant) and single posterior (S‐Post) implant prostheses, and a bridge (B) spanning from an anterior implant (B‐Ant) to a posterior implant (B‐Post). A commercial software was used to plan the implant location, design the surgical guides and design the provisional prostheses. The master models with the provisional prostheses were scanned to generate virtual master models. For each maxillary model, a total of 10 guides and 10 surgical models were produced. Following implant placements in each surgical model, the provisional prostheses were attached to the implants and were scanned to produce virtual surgical models. The virtual master and surgical models were superimposed to measure the vertical error, the proximal contact error and the proximal contact quality. Results The vertical error was greatest for the S‐Post (0.41 mm), followed by B‐Post (0.29 mm), B‐Ant (0.26 mm) and S‐Ant (0.21 mm). There was no significant difference in vertical errors among the prostheses. For the proximal contact, the S‐Ant had significantly greater error (0.45 mm ‐ 0.46 mm) than S‐Post (0.15 mm) and B (0.09 mm ‐ 0.15 mm). A similar pattern was observed for proximal contact quality. Conclusions All prostheses were associated with errors vertically and at the proximal contacts. Therefore, the clinicians who plan to use this workflow should be prepared to adjust the prosthesis after implant insertion.

“…compared the mechanical properties of CAD/CAM and the conventional heat-cured PMMA and found that CAD/CAM PMMA had significantly improved flexural strength, impact strength, and flexural modulus compared to conventional heat-cured PMMA (57). Nowadays, PMMA interim crowns are increasingly used on the implant with digital workflow (58,59).…”

This study was to investigate the damping capacity of implant-supported crowns made from various computer-aided design and computer-aided manufacturing (CAD-CAM) restorative materials.�A titanium implant fixture was embedded in epoxy resin.�Crown specimens were divided into three groups: Zirconia (Z), Lithium disilicate (E), and Polymethyl methacrylate�(P). Each crown was subdivided into Uncement�(Un) and Adhesive resin cement (RC) subgroups�(n=5). Specimens were loaded�(0-200N).�Strain gauges were attached to measure microstrains at crestal and apical levels. Damping capacity was determined based on load-time curves,�microstrain-time curves, and time required to reach the maximum load.�A two-way ANOVA with Tukey post hoc test and independent�t-test were conducted (?=0.05). The results showed that�slopes of curves�and time to reach maximum load were similar in the Z and E groups (p>0.05), but the P group exhibited less steep slopes and more time to reach maximum load (p<0.05). The UN group had significantly steeper microstrain slopes at crestal level and less time to reach maximum load compared to the AR group (p<0.05). In conclusion, the crown material significantly influenced the damping capacity, with lower modulus of elasticity materials showing higher damping capacity. Cementation enhanced�damping capacity in implant-supported crowns.
