“…This is below the survival rate of implants in the general population, which is estimated at 96.4% over a 10-year period by [28], and 92.6% over 27 years by [29]. Nevertheless, there is no strict contraindication to placing dental implants in DS patients [30].…”

Objectives: Down Syndrome patients are a particularly vulnerable group to teeth loss and periodontal disease. Therefore, the need for prosthetic rehabilitation is only a matter of time. The aim of this systematic review is to assess and summarize the available literature regarding the outcome of dental implants in patients with Down Syndrome. Materials and Methods: An electronic search was performed in Pubmed-Medline, Lilacs, and Cochrane Library. Search terms used were: “dental implant” OR “implant rehabilitation” AND “down syndrome”. Articles reporting the placement of implants in patients with down syndrome up until 2022 were included. Results: A total of 15 studies (10 case reports, 4 retrospective studies and 1 prospective study) comprising 234 implants placed in 61 patients were included. Implant failure occurred for 45 implants, leading to a survival rate of 80.7%. 12 studies out of 15 reported their results after a follow up period of 6 months to 4 years. Conclusion: The limited body of evidence suggests a survival rate of implants in Down Syndrome patients that is lower than among the general population. While several risk factors could explain these failures, there is still much to be answered regarding the mechanisms leading to implant rejection. A careful approach by dental practitioners should be the norm until better designed future studies with longer follow up periods can further shed light on the outcomes of implant therapy in Down Syndrome patients.

“…The ideal treatment option is to replace a missing tooth with a dental implant [1]. However, this option can be expensive, and many complications may occur due to medical (i.e., uncontrolled diabetes, several cancer therapies) and surgical conditions (i.e., insufficient bone volume) [2]. In these cases, an alternative treatment would be the conventional three-unit porcelain fused to metal (PFM) bridge.…”

Influence of Resin Cement Thickness and Elastic Modulus on the Stress Distribution of Zirconium Dioxide Inlay-Bridge: 3D Finite Element Analysis

The mechanical properties and the thickness of the resin cement agents used for bonding inlay bridges can modify the clinical performance of the restoration such as debonding or prosthetic materials fracture. Thus, the aim of this study was to evaluate the stress distribution and the maximum strain generated by resin cements with different elastic moduli and thicknesses used to cement resin-bonded fixed partial denture (RBFPD). A three-dimensional (3D) finite element analysis (FEA) was used, and a 3D model was created based on a Cone-Beam Computed Tomography system (CBCT). The model was analyzed by the Ansys software. The model fixation occurred at the root of the abutment teeth and an axial load of 300 N was applied on the occlusal surface of the pontic. The highest stress value was observed for the Variolink 0.4 group (1.76 × 106 Pa), while the lowest was noted for the Panavia 0.2 group (1.07 × 106 Pa). Furthermore, the highest total deformation value was found for the Variolink 0.2 group (3.36 × 10−4 m), while the lowest was observed for the Panavia 0.4 group (2.33 × 10−4 m). By means of this FEA, 0.2 mm layer Panavia F2.0 seemed to exhibit a more favorable stress distribution when used for cementation of posterior zirconium-dioxide-based RBFPD. However, both studied materials possessed clinically acceptable properties.
