“…48,49 However, they may have biological weaknesses if the emergence profile and the embrasure contour are inappropriately formed. 50 In the same vein, it is known that a wider emergence angle and overcontoured prosthesis can be risk factors for peri-implantitis. 51,52 Mechanical complications occurred more often than the aforementioned biological complication.…”

Background: In immediately loaded implants within 72 h after the implant placement in the unilaterally and partially edentulous ridge, primary stability is considered critical, which can be influenced by the design of the implant fixture.Purpose: To determine the outcomes at 1 year after the immediate loading of multiunit fixed partial prostheses over either tapered implants (TIs) or straight implants (SIs) in the posterior region.Materials and methods: Forty-eight patients (24 patients, 52 implants in TI group; 24 patients, 50 implants in SI group) were included for the study. Except for the one SI group patient whose two implants showed the insertion torque less than 30 Ncm, provisional prostheses designed and fabricated from intraoral scan data obtained immediately after implant surgery were delivered to rest of the 47 subjects at 3-7 days. After a year, the survival rate was estimated by intention-to-treat (ITT) and per-protocol (PP) analyses, and marginal bone loss (MBL) and implant stability were also analyzed statistically (p < 0.05).Results: Survival rate at implant level in TI group was 96.2%, and that of SI group in the ITT analysis was 86.0%. Intergroup difference, however, was not statistically significant (p > 0.05). Insertion torque was significantly higher in TI group than SI group (47.12 ± 6.37 Ncm vs. 41.60 ± 9.77 Ncm; p < 0.05). MBLs of both groups were less than 0.1 mm at 1-year follow-up and was similar between two groups (p > 0.05).Conclusions: Immediate loading of fixed partial prostheses after TI and SI placement showed reliable outcomes in the partially edentulous posterior ridge. In terms of the initial mechanical stability, the performance was superior for TIs than for SIs.dental implant, immediate loading, implant survival rate, peri-implant marginal bone loss, randomized clinical trial Yoo-Yeon Kim and Young Woo Song contributed equally to this study.

“…Overload may cause mechanical complication/ failure of the restoration and/or implant and biological failure of the surrounding bone. [1][2][3][4] In order to minimize those complications, some authors recommended splinting implant restorations where biomechanical risks are high, such as posterior region in an attempt to distribute the occlusal forces over a bigger resistance area. [5][6][7] A split-mouth prospective study of splinted ipsilateral implants and nonsplinted contralateral implants showed that all screw loosening complications occurred on the nonsplinted side for 5 of 15 patients.…”

Purpose: The purpose of this study was to retrospectively evaluate the effects of splinting implant crowns against nonsplinted crowns on the failures and complications of multiple adjacent implants. Material and methods: A retrospective chart review was conducted of all registered implant patients treated at the University of Minnesota School of Dentistry from 1988 to 2018. A total of 2738 implants within 1171 sections of 890 patients were examined retrospectively using an inclusion criteria of (1) two or more adjacent implants (section) present and (2) implants were restored by splinted crowns (Splinted group) or nonsplinted (individual) crowns (Nonsplinted group). Results: An average follow-up interval was significantly longer (p < 0.0001) for Splinted (median 5.52 [IQR 1.97, 9.67] years) compared to Nonsplinted (3.76 [1.49, 6.54] years). Splinted group’s Hazard ratio (HR) for implant failure was 0.67 (95% CI 0.35–1.31, p = 0.24) relative to Nonsplinted, and estimated 5- and 10-year failures rates were 2.5 (1.3–3.7) vs. 3.0 (1.9–4.0)% and 8.7 (6.1–11.3) vs. 8.6 (5.7–11.3)%, respectively. Splinted group’s HR for total complication relative to Nonsplinted was 0.98 (95% CI 0.71–1.36, p = 0.92) and estimated 5- and 10-year complication rates were 24.7 (21.7-27.5) vs. 23.7 (21.1-26.3)% and 38.1 (34.2-41.7) vs. 42.1 (37.2-46.6)%, respectively. Three most common complications (Splinted/Nonsplinted, 10-year estimates) were crown decementation/dislodgement (20.8/13.0%), peri-implantitis (12.2/13.1%), and screw loosening (5.9/12.8%), while 3 failure causes (5-year estimates) were peri-implantitis (1.8/1.3%), implant fracture/metal collar flowering (0.3/1.1%), and soft tissue encapsulation (0.1/0.2%). When 380 Lifecore implants with higher failure rates (8.4% in 7.2 years) were excluded, the implant failure HR became lower 0.46 (0.22–0.99, p = 0.05) indicating significantly lower implant failure risk in Splinted compared to Nonsplinted, while the total complication HR did not change much 0.95 (0.64–1.40, p = 0.79). When compared per section, Splinted total complication HR went down to 0.75 (0.55–1.02, p = 0.07), indicating lower risk for complication in Splinted sections compared to Nonsplinted sections. Conclusion: The trends of implant therapy of multiple adjacent implants have changed over the last three decades. The effects of splinting crowns of multiple adjacent implants were not significant in reducing implant failures or total complications. However, when the Lifecore implants mainly used in Splinted group during earlier phase (1988 – 2003) were excluded, the Splinted group showed significantly lower implant failure risk than Nonsplined group.
