“…The better manner of estimation of an implant solution is to show the zone of destruction or the zone exposed to atrophy from overloading. Especially, that in case of cyclic mastication loads, the stresses beyond 28-35 MPa are critical for bone tissue disuse at a long-term effect [19]. In presented analysis the zone of atrophy was in agreement with typical bone atrophy at the margin after one year of loading.…”

“…The stresses in bone tissue surrounded the implant under occlusal force of 800 N and during bearing the mastication load was compared on Fig.6. The areas of the bone tissue in which the stresses exceed allowable instantaneous limit of 140 MPa and average allowable fatigue limit of 30 MPa [19] were visualized. The stresses in the tooth associated with bearing the mastication load were shown on Fig.7.a.…”

Implant and a tooth supported dentures are avoided by dentists because of uneven distribution of occlusal loads between a stiffer implant and a more pliable tooth. The hypothesis was that a 3-point all-ceramic bridge supported on a natural second premolar tooth and a two-pieces typical implant bears safely mastication loads. The finite element analysis showed that the implant splinted by all-ceramic zirconium bridge with the second premolar was safe under lateral mastication load, but there was found an overload at wide zone of bone tissue around the implant under the load of 800 N. The patients can safely masticate, but comminution of hard food should be avoided and they should be instructed that after such an indiscretion they need to contact a dental professional, because, in spite of integrity of the prosthesis, the bone tissue around the implant may fail and there is a hazard of intrusion of the tooth.

“…[1][2][3] Since the beginning of osseointegration, when the Brånemark protocol composed of a fixed prosthesis with five or six implantations as pillars in the mental region and bilateral cantilevers was proposed, there has been an interest not only in determining the most suitable occlusal configuration, providing a harmonious and effective disclusion, but also in understanding the relationships of this configuration with the stomatognathic system. 4 Thus, the relationship between the involved occlusal factors and chewing muscles, masticatory efficiency, bruxism, temporomandibular articulation, adjacent tissues, etc.…”

Stress analysis on the free-end distal extension of an implant-supported mandibular complete denture

A comparative and qualitative analysis of the tensions generated in the cantilever region of an implant-supported mandibular complete denture was conducted using the three-dimensional finite element method. The mechanical properties of the components were input in the model and a load of 15 N was applied in pre-determined points. In the first simulation, the load was applied on the occlusal surface of the first premolar. In the second simulation, it was applied on the first and second premolars. In the third simulation, it was applied on the first and second premolars and on the first molar. The different occlusion patterns produced similar tension distributions in the cantilever region, which followed a similar pattern in the three simulations. In all of the cases, the highest levels of tension were located in the region of the first implant. However, as the loads were dislocated distally, the tensions increased considerably. The more extensive the cantilever, the more compromised will be the infrastructure, the prosthetic components and the implants. Regardless of the length of the cantilever, the highest tensions will always be located in the region of the implant next to the load application point.

Palabras clave-Biomecánica y simulación, Implante, Modelos de elementos finitos, Torque.Abstract-The main purpose of this research was the development of a study to determine the values of insertion torque recommended to reduce the likelihood of generating pathological overload of mandible molar region due to insertion torque applied to adjust the dental implant. Ti6Al4V dental implants were manufactured to be inserted into bone tissue specimens of human cadaver jaw and similar densities of bone substitute specimens Sawbone ® normalized like bone density D2 type. Then were measured the insertion torque data recording to adjust the implant at samples. Data from the test were used in simulations based on the finite element method. Through the elastic strain criteria, it was known the strain values less than 0,4% of the elastic strain at the bone implant interface. Based on outputs case study, the values of insertion torque to be applied to insert implants surgery are recommended.
