“…This bone level change corroborates well with previously published data for the OsseoSpeed implant, short implants 21,22,29,[31][32][33][34]37,[39][40][41] as well as for standard length implants. 15,16,[42][43][44][45] In this study, 4 early implant failures occurred and one implant rotated at 5 weeks post-surgery.…”

“…25,30,31 Nevertheless, there is no evidence for such and longer OsseoSpeed implants. 39 The author's conclusion from this split-mouth study was that marginal bone levels were equally well maintained at short implants as at regular length implants. It is very interesting that the non-splinting of 6 mm-short implants revealed a gain in bone at 24 and 36 months compared with baseline.…”

“…Short implants are recommended for maxillary posterior region (molar) due to poor availability of bone tissue; however, short implants are more susceptible to failures rates than conventional implants (6). Thus, the splinting of short implants with implants of longer length is indicated in these situations (4). Splinted crowns help to distribute the stress between the splinted implants.…”

“…The make decision about the use or not of splinted crowns is based on different factors such as: implant length, occlusion, hygiene, connection type and difficulty achieving a passively fitting framework (4). The maxillary posterior area after tooth loss often can limits the use of the longer implants.…”

“…However, short implants may present greater risks when compared to implants with conventional lengths, especially when placed in the posterior region (6). Thus, the splinted crowns of short implants can be indicated in atrophic maxilla because transmit more uniform stress in structures with higher reduction of stress in the periimplant region (4).…”

Retention System and Splinting on Morse Taper Implants in the Posterior Maxilla by 3D Finite Element Analysis

et al. 2018

The purpose of this study was to evaluate different retention systems (cement-or screw-retained) and crown designs (non-splinted or splinted) of fixed implant-supported restorations, in terms of stress distributions in implants/components and bone tissue, by 3-dimensional (3D) finite element analysis. Four 3D models were simulated with the InVesalius, Rhinoceros 3D, and SolidWorks programs. Models were made of type III bone from the posterior maxillary area. Models included three 4.0-mm-diameter Morse taper (MT) implants with different lengths, which supported metal-ceramic crowns. Models were processed by the Femap and NeiNastran programs, using an axial force of 400 N and oblique force of 200 N. Results were visualized as the von Mises stress and maximum principal stress (σ max ). Under axial loading, there was no difference in the distribution of stress in implants/components between retention systems and splinted crowns; however, in oblique loading, cemented prostheses showed better stress distribution than screwed prostheses, whereas splinted crowns tended to reduce stress in the implant of the first molar. In the bone tissue cemented prostheses showed better stress distribution in bone tissue than screwed prostheses under axial and oblique loading. The splinted design only had an effect in the screwed prosthesis, with no influence in the cemented prosthesis. Cemented prostheses on MT implants showed more favorable stress distributions in implants/components and bone tissue. Splinting was favorable for stress distribution only for screwed prostheses under oblique loading.

Analysis of stress/strain distribution in dental mini‐implants manufactured by additive manufacturing and machining

The study aimed to analyze the stress/strain distribution of new designs of miniimplants manufactured by machining and additive manufacturing. Four designs were evaluated (Ø2.0 mm Â 10 mm): Intra-lock, helical, threaded machined (MN threaded) and threaded by additive manufacturing (AM threaded). Analysis of stress was performed through photoelastic analysis (100 N axial/oblique loads) and analysis of strain by digital image correlation (DIC) (250 N axial/100 N oblique load). Data distribution was verified using the Shapiro-Wilk test and a significance level of 5% was adopted. Quantitative data were analyzed using the non-parametric Kruskal-Wallis test. In photoelastic analysis, the Intra-lock mini-implant showed the highest stresses in the cervical (104 kPa), middle (108 kPa), and apical (212 kPa) thirds. Higher stresses were observed in the oblique loading situation for all designs. For DIC analysis, axial loading, a significant difference was observed for the AM Threaded miniimplants about the other designs in the cervical third (p = .04), with the highest strain value 47 με [10; 76]. In oblique loading, a significant difference between the miniimplants was observed in the middle and apical thirds, with higher strains for the AM threaded design À185 με [À173; 162] (p = .009) and 242 με [87; 372] (p = .013), respectively. In general, the influence of different mini-implant designs and the additive manufacturing method on the stress/strain was observed, in the photoelastic and DIC analysis. The evaluated designs demonstrated a lower concentration of stress/strain in the cervical region compared to the apical region, and higher stress/ strain in situations of oblique load compared with axial load.
