“…It is worth noticing that the resistance to fracture progressively increased with occlusal thickness and the failure mode became more favorable; consequently, differently from the behavior of ceramic materials, thicker cores could enhance the clinical longevity of Cerasmart restorations thanks to the shock adsorbing capability of the high density nanoparticle-filled composite resin matrixx [17]. Furthermore, the clinical performances are strongly related both to the type of resin cement and to the accuracy of adhesive procedures [6,12,19].…”

“…Although fracture patterns were similar, significant differences between CAD-CAM composite and ceramic crowns were reported; indeed, resin-based restorations exhibited longer endurance limits before unrestorable fractures [16]. Furthermore, it was pointed out that CAD-CAM composite-based blocks have better shock absorbing properties than similar ceramic materials, although these results still remain partly controversial [17,18]. To date, very few studies are available about Cerasmart and its advantages and limitations should be investigated and better understood both in vitro and in vivo [14].…”

“…19 This choice was made in the attempt to reduce the load on the implant. Even though the intensity, frequency and duration of the occlusal overload could not be measured, the implant was considered overloaded because the patient chew only with the left side of his mouth, as the elements 45, 46, 47 had been extracted.…”

“…However, the amount of load to be defined as overload has not been quantified, also because the range of host physiological adaptability varies. 19 Up to now, clinical evidence on the impact of overloading on peri-implant bone is not available. The inability to quantitatively define overloading, as well as several methodological and ethical limitations, has seriously compromised the potential of human studies to draw valid conclusions.…”

This paper presents a case report where the influence of plaque accumulation and overload on a dental implant was observed. The patient presented crown loss on one implant affected by peri-implant bone resorption and gingival inflammation associated with poor oral hygiene. After 12 months a single crown was delivered, but as soon as the occlusal load was applied bone loss and implant failure occurred. In the present case report the dental implant remained stable as long as the implant was not loaded, although a 100% plaque index and bleeding on probing were present during the entire followup period. In contrast, as soon as an occlusal load was applied periimplant bone loss and implant failure occurred. These observations suggest that plaque accumulation alone is not a triggering factor for peri-implant bone loss and implant failure. On the contrary, occlusal load, when not properly controlled, might cause bone resorption.

“…In the literature, veneering materials have been reported to absorb most of the energy, in contrast to the larger displacement and deformation of materials with a low Young's modulus (Ciftçi & Canay, 2001). Also, materials with a high Young's modulus were found to have less deformation under a load, with the stresses probably transferred through the material (Menini et al, 2013).…”

The purpose of this study was to evaluate through finite element analysis (FEA) the total deformation or displacement as a whole system of multiple implant-supported prostheses in the maxillary anterior region with different implant's length, connection, location and restoration material. An edentulous anterior region of a hemi-maxilla model was used in finite element analysis. The simulations were divided in two groups according to treatment plan: 1) two implants were placed in the upper central incisors, simulating an implant-supported fixed prosthesis (acrylic resin and metal-ceramic) of four elements with cantilever of both upper lateral incisors; 2) two implants placed in the upper lateral incisors, simulating a conventional fixed prosthesis of four elements with both upper central incisors as pontic. Models with cantilever prosthesis in acrylic resin showed the highest values of total deformation, which were 17 times higher than those of metal-ceramic in the distal face of the lateral incisors, regardless of the type of implant connection. In conventional prostheses in acrylic resin, external hexagon connections had lower total deformation values compared with morse taper connection. Also, the implant length was found to have no effect on the values of total deformation. In conclusion, total deformation was substantially greater in all models with acrylic resin restorations.
