WHY NOT TO NEGLECT MECHANICAL PROBLEMS WITH THE IMPLANT?
Turkey Medicals, “Mechanical damage to implants may occur over time due to overload. Regular maintenance can prevent problems that will be encountered. What mechanical problems are encountered after the implants are applied to the jaw surface, we talk about them,” was said.
Let it be started by describing the occlusion that you will often encounter. Occlusion is the name given to the closing process and the state of being closed. Mechanical complications may occur as a result of an occlusal loading. The frequency of component deconstruction varies widely between reviewed articles. Fatigue of the implant components is considered a biomechanical overload sequela. In the worst case, an overload will result in a fatigue breakage of the fixture.
Other complications may include screw loosening, screw breaks, cementum decays, frame breakage, wear or breakage of the cladding material. There may also be the problems with the holding prosthesis on a mechanical tooth…

FRACTURE OF THE IMPLANT
Research in Turkey shows that the implant fracture rate varies between 0-14 percent. The occurrence of an implant fracture is associated with bone loss that has been subjected to excessive load. Pitting of the bone has also been reported before the determination of the implant fracture. Studies conducted on patients whose implants were broken show that 60 percent of these implants that were broken had previously experienced mechanical complications such as loosening or breaking the screws. Therefore, mechanical problems should be addressed without any delay. Prosthetic intervention may include returning to prosthetic design and occlusion and installing additional implants. Maximizing the implant support for a prosthesis can reduce the bending fatigue of the metallic components inside. In order to minimize the distribution of stress and torque, it is recommended to place the prostheses flush with the implant-mounted part. It is also advocated to install two implants instead of a single molar. This application will provide more surface area for osseointegration and will be able to spread the occlusal loading over a larger area by reducing the bending forces that may possibly occur in otherwise single implant molar restoration.

NON-COMPLIANCE WITH THE REPLACEMENT OF THE PROSTHESIS
Some studies have specifically examined the effects of implant restorations on osseointegration on non-compliance. Many authors have stated that passively fitting a prosthesis is a prerequisite for achieving successful integration. To date, the authors who conducted research in this area have not been able to prove the negative consequences of non-compliance of the bone/implant interface. It remains to determine whether there is damage to the bone/ implant interface in case of non-compliance with any quantity. However, if the prosthesis does not fit into place, it is likely that the component will loosen and break.
.
SCREW LOOSENING
The decoupage of the abutment screw varies from 1 to 35 percent of abutments. The prosthetic screw decoupling varies between 1 and 38 percent. The factors on which screw loosening is based are: occlusion, fitting the prosthesis into place, screw design and its formation. Over the years, manufacturers have modified the components in order to reduce the problem of screw loosening. The transition to gold-alloy screws allowed more effective compression for larger front loads due to a lower coefficient of friction than titanium. In order to reduce the friction resistance, dry lubricant coatings were applied to the abutment screws. The effectiveness of this screw joint stability technology needs to be fully documented in further independent research and clinical trials.
.
Screw loosenings are usually detected by mobility testing or radiographic examination in control examinations. It remains unclear exactly what triggered the screw loosening encountered by most researchers. However, routine back compression is recommended for control examinations.
.
SCREW BREAKS
It is often found that the screws of the prosthesis and the abutment are broken. Initially, it was thought that the prosthetic screw could break before the other components because it is smaller and weaker than the fulcrum screw. Studies show that the fulcrum screw is often broken, although not as much as the prosthetic screw. A mechanical hypothesis has been prepared to explain this. The implant support interface corresponds to the level at which the bone support ends and the maximum bone hardness level. This increased rigidity strengthens the tension localized in the area of the crest around the cheek of the implant. The fulcrum screw can be subjected to much greater force and, although it is a more massive structure, is more susceptible to fatigue deterioration. Patients and physicians should be aware that screw breakage is not an uncommon complication in world implant therapy.
.
COMPLICATIONS DUE TO CEMENTATION
Implant restorations may seem tempting to compensate for the cementation prosthetic incompatibility. But the disadvantage of this procedure is that the chances of restoring the implant are lost. Some physicians have advocated the use of temporary cements to overcome this problem, but no definite success has been achieved. In the long term, implant-assisted restorations may require correction or revision, and a temporary cementum may not always allow predictable recovery. The ability to disassemble a prosthesis makes it easier to maintain it during control examinations. Other retaining devices, such as lateral set screws or lingual composite stoppers, are newer aesthetic and retrievable options.
.
FRACTURE OF THE FRAME/PROSTHESIS
Metal frame breakage occurs due to reasons such as insufficient metal thickness, bad solder joints, excessive console length, alloys, insufficient strength, parafunctional habits of the patient, and incorrect frame design. Acrylic resin fractures for implant dental prostheses are usually caused by insufficient space. The use of a metal-reinforced dental prosthetic base can minimize this complication. Acrylic resins and composites tend to break more in fixed partial dentures than porcelain veneer materials. Since studies have not been able to identify a more superior coating material, porcelain has been used more often for aesthetic reasons in recent years. A high number of dental complications associated with clips and attachments have been reported. These components tend to loosen and break down over the time, and they need to be replenished regularly.

RESULT
Turkey Medicals, “The best physicians who perform dental implant treatment for their patients should be familiar with the possible complications and care of such restorations. These complications; a standardized data collection method further strengthens our knowledge about etiology and frequency of these complications. Regular care and addressing these complications can appropriately extend the life of implant restorations,” was said.
