Biomechanics of Dental Implants

Dental Implant

What Are the Forces on My Implants?

Fibrous tissue presence has known to lessen the long-term rate of survival for root form implants. Higher than normal loads on an absorbed implant can result in movement of the device even after a bone-implant interface has been undertaken. Our surgeons can explain these issues to patients, ensuring a well-informed decision is made if a patient is seeking one dental implant procedure or may be interested in the full mouth dental implants.

Many different conditions may cause bone loss in patients but one key condition that can be a factor is prosthetic overload. Excessive loading can cause increased strain conditions in the bone, reports show, and microstrains may affect the bone’s remodeling rate and result in pathologic overload conditions and the loss of bone as a result. The amount of strain on the bone is always related to the stress applied to the interfacing bone and implant. The greater the stresses throughout the interface, there is a far higher risk of bone loss. That means the stress and strain situation is shown to be an important factor in maintain crestal bone and the rate of implant survival. Forces applied to dental implants are often characterized in five distinct factors. Each is related to the other. They include factors such as Magnitude, Duration, Type, Direction and Magnification. Each can be viewed within the physiologic constraints on the size of the implants. Moreover, are surgical and prosthetic considerations related to implant size are also key factors.

Force Magnitude

Stomatognathic system physiology imposes a varied range of forces that apply to implant within the oral environment of the patient. Bite force varies as a function of anatomical region and state of the patient’s teeth, and, on average, bite forces range from about nine or 10 lbs. to well over 30o lbs. The magnitude of force is strongest in the typical patient’s molar area (as much as 200 lbs.), less strong in the canine area (half of the molar area forces, and smallest in the front incisor region (roughly 20 to 40 lbs.). These bite forces, on average, can increase to far higher magnitudes in the back regions of the bite process.

After lengthy periods of full tooth loss, bone and foundations often transform to less dense bone. Studies on normal dentate and toothless jaws show far more trabecular bone in the frontal regions as contrasted with molar regions and pre-molar areas. The ultimate strength of the bone can highly depend on its inherent density. That means that less dense bone mass can sometimes not support a patient’s normal occlusal forces.

With good treatment plans in place and thoughtful size selection for implants results of less load magnitude on the implant-bone areas under difficult conditions. In most patients, the posterior regions with greater occlusal forces and less dense bone may require varied and different implant size parameters when contrasted with the frontal regions. In addition, those front regions are more often important in the patients’ appearance perception and can be a major influence in decisions on implant size.

Force Duration

Bite force duration in teeth covers a varying range as varied as human kind. In normal conditions, teeth generally meet during swallowing and dining quite briefly throughout normal contacts. The time of teeth contact episodes is generally under a half-an-hour each day. Patients who suffer from bruxism and clenching or other dysfunctional habitual chewing, etc., can result in having teeth making contact for as many as several hours daily.  Fatigue fractures thus increase in relationship to the direct amount of the force and the number of load cycles in patients. Increased duration of such forces can far increase the risk of fatigue to implants and be greater than the prepared endurance limits of the implant and its parts. The body width of the implant is always related to the strength of an implant and the wider implant is generally reduces fracture risks from fatigue. Biting duration and forces from it can hinder the implant-bone relationship, as well.

Force Type

Three kinds of force impact dental implants within the mouth and oral cavity. They include the forces of compression and tension along with shear. Jawbones are stronger when in compression, a third more weak when subjected to tensile forces, and about half as strong when loaded in shearing conditions. Dentists should encourage patients to lessen shear forces on bone since implants are most prone to break off in these kinds of loading conditions. This is critical in areas of less bone density since the bone strength is quite related to the state of its density. Wider implants may decrease loads and increase the implant-bone interface area under compressive loads.

Force Direction

Implant body forces are generally strongest when at the crestal bone conjunction, and loads to the implant prosthesis caused angled loading to the implant crest module. By increasing the angle of the load by only 6 degrees, the lateral component of that load is increased more than two times. Also, each degree of the angle can increase shear load damage of the implants, and presents the highest load component damage likelihood.

Force Magnification

Magnification of force increases stresses beyond the usual load conditions. Multiple force magnifiers, such as a patient with an excessive tall crown, can cause the dental implant not to adequately withstand the normal loading and damage the implant.

Financing care for implants

We can offer assistance in arranging payment plans for dental implant treatment and care. Insurance plans, in some instances, can cover part of the fees. We also can assist patients with finding financing arrangements in many cases. If you are asking how much are dental implants and where can I find dental implants near me, we are here to assist you.
