“…The results of the current study are strongly related to and in line with a recently published clinical study [ 52 ]. This study evaluated the effect of implant-supported fixed porcelain-to-metal dentures and indirect composite resin on peri-implant marginal bone resorption, and no difference was found at 18-month follow up.…”

Background: The objective of this study was to evaluate the load transmitted to the peri-implant bone by seven different restorative materials in single-unit rehabilitations with morse taper implants using a strain gauge. Materials: In a polyurethane block that simulated type III bone, a morse taper platform implant was installed (3.5 × 11 mm) in the center and 1 mm below the test base surface, and four strain gauges were installed around the implant, simulating the mesial, distal, buccal and lingual positions. Seven similar hybrid abutment crowns were crafted to simulate a lower premolar using different materials: 1—PMMA; 2—glass ceramic over resin matrix; 3—PEEK + lithium disilicate; 4—metal–ceramic; 5—lithium disilicate; 6—zirconia + feldspathic; 7—monolithic zirconia. All groups underwent axial and oblique loads (45 degrees) of 150 N from a universal testing machine. Five measurements (n = 5) were performed with each material and for each load type; the microdeformation data underwent statistical analysis. The data were obtained in microdeformation (με), and the significance level was set at p ≤ 0.05. Results: There was no statistically significant difference in the evaluation among the materials under either the axial load or the oblique load at 45 degrees. In turn, in the comparison between axial load and oblique load, there was a difference in load for all materials. Conclusion: The restorative material did not influence the load transmitted to the bone. Furthermore, the load transmitted to the bone was greater when it occurred obliquely at 45° regardless of the material used. In conclusion, it appeared that the different elastic modulus of each material did not influence the load transmission to the peri-implant bone.

“…However, based on the current literature search, 6 RCTs are available, comparing titanium and zirconia implants (Koller et al, 2020; Osman et al, 2014; Payer et al, 2015; Ruiz Henao et al, 2021), immediately and conventionally loaded zirconia implants (Cannizzaro et al, 2010) or porcelain‐fused‐to‐metal and indirect‐composite‐resin fixed dental prosthetics on zirconia implants (Aldebes et al, 2022). However, 4 studies investigated zirconia implants that are not commercially available, respectively, were removed from the market (Cannizzaro et al, 2010; Koller et al, 2020; Osman et al, 2014; Payer et al, 2015), investigated the same patient population (Koller et al, 2020; Payer et al, 2015) and/or used a novel, unestablished surgical protocol combining alveolar and palatal implants in the maxilla (Osman et al, 2014) or evaluated individually designed, custom‐made zirconia implants (Aldebes et al, 2022). Only 1 RCT investigated 16 currently marked available zirconia implants in comparison to 14 titanium implants.…”

ObjectivesFor the present review, the following focused question was addressed: In patients with root‐analog dental implants, what is the effect of implants made of other materials than titanium (alloy) on implant survival, marginal bone loss (MBL), and technical and biological complications after at least 5 years.Materials and MethodsAn electronic (Medline, Embase, Web of Science) search was performed to identify observational clinical studies published from January 2000 investigating a minimum of 20 commercially available zirconia implants with a mean follow‐up of at least 60 months. Primary outcome was implant survival, secondary outcomes included peri‐implant MBL, probing depths (PDs), and technical and biological complications. Meta‐analyses were performed to evaluate implant survival, MBL, and PD.ResultsFrom 5129 titles, 580 abstracts were selected, and 111 full‐text articles were screened. Finally, 4 prospective and 2 retrospective observational clinical cohort studies were included for data extraction. Meta‐analyses estimated after 5 years of loading mean values of 97.2% (95% CI 94.7–99.1) for survival (277 implants, 221 patients), 1.1 mm (95% CI: 0.9–1.3) for MBL (229 implants, 173 patients), and 3.0 mm (95% CI 2.5–3.4) for PDs (231 implants, 175 patients).ConclusionsAfter 5 years, commercially available zirconia implants showed reliable clinical performance based on survival rates, MBL, and PD values. However, more well‐designed prospective clinical studies and randomized clinical trials investigating titanium and zirconia implants are needed to confirm the presently evaluated promising outcomes.

“…This higher survival rate may explain the surface treatment's role in facilitating tighter cell-titanium interactions, which enhance the bone tissue's biological and biomechanical effects [162]. Aldebes et al [163] observed that the mean MBL of one-piece modified anatomic zirconia implants was 0.61 mm in the low bone type. The findings also indicated that the one-piece design and zirconia implant material, considered tissue-friendly and biocompatible, may offset lower MBL.…”

Titanium has been the material of choice for dental implant fixtures due to its exceptional qualities, such as its excellent balance of rigidity and stiffness. Since zirconia is a soft-tissue-friendly material and caters to esthetic demands, it is an alternative to titanium for use in implants. Nevertheless, bone density plays a vital role in determining the material and design of implants. Compromised bone density leads to both early and late implant failures due to a lack of implant stability. Therefore, this narrative review aims to investigate the influence of implant material/design and surgical technique on bone density from both biomechanical and biological standpoints. Relevant articles were included for analysis. Dental implant materials can be fabricated from titanium, zirconia, and PEEK. In terms of mechanical and biological aspects, titanium is still the gold standard for dental implant materials. Additionally, the macro- and microgeometry of dental implants play a role in determining and planning the appropriate treatment because it can enhance the mechanical stress transmitted to the bone tissue. Under low-density conditions, a conical titanium implant design, longer length, large diameter, reverse buttress with self-tapping, small thread pitch, and deep thread depth are recommended. Implant material, implant design, surgical techniques, and bone density are pivotal factors affecting the success rates of dental implant placement in low-density bone. Further study is required to find the optimal implant material for a clinical setting’s bone state.
