“…Similarly, Papavasiliou et al (10) demonstrated that oblique forces increased the stress concentration in the implant and bone. These results are also in accordance with the literature that describes the influence of increase in crown height on the transference of occlusal forces (9,11,13,15,(18)(19)(20)(21)(22)(23)(24).…”

The purpose of this study was to assess the influence of the crown height of external hexagon implants on the displacement and distribution of stress to the implant/bone system, using the three-dimensional finite element method. The InVesalius and Rhinoceros 4.0 softwares were used to generate the bone model by computed tomography. Each model was composed of a bone block with one implant (3.75x10.0 mm) with external hexagon connections and crowns with 10 mm, 12.5 mm and 15 mm in height. A 200 N axial and a 100 N oblique (45°) load were applied. The models were solved by the NeiNastran 9.0 and Femap 10.0 softwares to obtain the results that were visualized by maps of displacement, von Mises stress (crown/implant) and maximum principal stress (bone). The crown height under axial load did not influence the stress displacement and concentration, while the oblique loading increased these factors. The highest stress was observed in the neck of the implant screw on the side opposite to the loading. This stress was also transferred to the crown/platform/bone interface. The results of this study suggest that the increase in crown height enhanced stress concentration at the implant/bone tissue and increased displacement in the bone tissue, mainly under oblique loading.

“…The correct implant position and inclination were established with a surgical guide, and a conventional 2-step technique was used (Blanes et al, 2007). After 1 week, RDPs were adjusted and relined with resilient soft lining material (Ufi Gel P; Voco, Cuxhaven, Germany) for use during the 4-month osseointegration period.…”

“…Several clinical studies indicated a maximum probe penetration of 3 mm for successful implants [15,46,48,51]. The two year longitudinal study of Brägger et al [13] confirmed that the measurements of probing attachment level (PAT) along with radiographic parameters were good predictors of peri-implant bone level.…”

-The loss of bone around implants is, on an average, below 1 mm during the first year and 0.2 mm per year in the years that follow. It essentially depends upon biomechanical factors but the level at which the bone stabilizes is determines by the implant depth. Intraoral radiographs (paralleling technique) are considered as the "firs choice2 for the evaluation of the radiolucency with respect to the proximal peri-implant bone. This study was based on 528 implants placesd in private practice, with an objective to determine their success rate and their survival at 5-6 years, to evaluate the peri-implant proximal bone loss and outline the factors that could influence this bone loss. The results obtained from 411 accessible patient files are in accordance with the literature date (at 5-6 years, the survival rate is 99.2%, the success rate is 93%, the average bone los sis 1.16 mm). The bone loss was more severe in smokers and in implants with a TPS surface, those placed in the anterior regions or those with vestibular cortical bone below the 1 mm. Short implants were not associated with a more severe bone loss than longer implants.

A 10‐year prospective study of ITI dental implants placed in the posterior region. I: Clinical and radiographic results

Abstract: ITI dental implants placed in the posterior jaw demonstrate excellent long-term clinical success. Hollow-cylinder implants seem to display a higher risk for crestal bone loss. Recession depth and attachment levels appear to be good clinical indicators of peri-implant bone loss.
