With the growing use of dental implants, the incidence of implants' failures grows. Late treatment complications, after reaching full osseointegration and functionality, include mechanical failures, such as fracture of the implant and its components. Those complications are deemed severe in dentistry, albeit being usually considered as rare, and therefore seldom addressed in the clinical literature. The introduction of dental implants into clinical practice fostered a wealth of research on their biological aspects. By contrast, mechanical strength and reliability issues were seldom investigated in the open literature, so that most of the information to date remains essentially with the manufacturers. Over the years, implants have gone through major changes regarding the material, the design, and the surface characteristics aimed at improving osseointegration. Did those changes improve the implants' mechanical performance? This review article surveys the state-of-the-art literature about implants' mechanical reliability, identifying the known causes for fracture, while outlining the current knowledge-gaps. Recent results on various aspects of the mechanical integrity and failure of implants are presented and discussed next. The paper ends by a general discussion and suggestions for future research, outlining the importance of mechanical considerations for the improvement of their future performance.

“…The surface roughness produced by shot blasting and the compressive residual stress can favor the fatigue life of the dental implant. However, the connection surface where the load is applied and the strength of the material used are key parameters for the long-term mechanical properties of the dental implant [10][11][12]. Thus, the assessment of the fatigue behavior of implantable alloys has been taking greater importance.…”

“…The materials used, fabrication process, and effective connection surface can be optimized in order to obtain a narrow dental implant with excellent static and dynamic mechanical properties. There is very little known about the fatigue of these narrow implants, and the durability and success rate have been described by only a limited number of clinical reports [10,13,14].…”

Fatigue of Narrow Dental Implants: Influence of the Hardening Method

et al. 2020

The use of narrow titanium dental implants (NDI) for small ridges, reduced interdental space, or missing lateral incisors can be a viable option when compared to the conventional wider dental implants. Furthermore, in many cases, standard diameter implant placement may not be possible without grafting procedures, which increases the healing time, cost, and morbidity. The aim of this study was to analyze the mechanical viability of the current narrow implants and how narrow implants can be improved. Different commercially available implants (n = 150) were tested to determine maximum strength, strain to fracture, microhardness, residual stress, and fatigue obtaining the stress–number of cycles to fracture (SN) curve. Fractography was studied by scanning electron microscopy. The results showed that when the titanium was hardened by the addition of 15% of Zr or 12% cold worked, the fatigue limit was higher than the commercially pure grade 4 Ti without hardening treatment. Grade 4 titanium without hardening treatment in narrow dental implants can present fractures by fatigue. These narrow implants are subjected to high mechanical stresses and the mechanical properties of titanium do not meet the minimal requirements, which lead to frequent fractures. New hardening treatments allow for the mechanical limitations of conventional narrow implants to be overcome in dynamic conditions. These hardening treatments allow for the design of narrow dental implants with enhanced fatigue life and long-term behavior.

“…Osseointegration is enhanced by a series of surface modications, such as grit-blasting/thermo-chemical treatment, 1 grit-blasting/acid etching, 2 electrodeposits, 3 deposition by lasers, 4 and microarc oxidation. 5 Many studies have investigated the feasibility of applying cell sheets to bone regeneration, 6 cardiac regeneration, 7 cartilage regeneration, 8 tendon healing, 9 corneal regeneration, 10 esophageal regeneration, 11 periodontal regeneration, 12 and full thickness skin wound repair.…”
