It is rather rare for a dental implant to fail. However, when that happens, the dental implant must be removed. The dentist will re-evaluated as to why the failure occurred and to see if that implant needs to be substituted. The common factors for dental implant failure includes:

 

1) Failed Integration of Dental Implants — This occurs when the bone does not grow and fuse in between the threads of the implant. This fusion of the bone to dental implant is called osseointegration. If this does not occur, the dental implants will not function correctly, will become uncomfortable, loose, or come out altogether. To reduce this risk, the dentist needs to evaluate the quality and density of the jaw bone prior to the surgery. This step is crucial to ensure that dental implants are placed only where there is an incredibly predictable success rate. If osseointegration does not happen, the dental implants can be removed, and surgery can be re-attempted once the area has healed over time.

 

2) Infection – The most frequent complication of dental implant surgery. The surrounding bone and gums can get infected during the surgical procedure. Infections happen due to various reasons such as non-sterile technique, poor healing ability (diabetic, smoker, osteoporosis medications, etc.), or pre-existent disease. It is highly likely to occur during the placement of the dental implant into the jawbone as well. Poor hygiene, massive force placed on the implant, or excess cement can cause the support tissue to break down. Implant infection is a condition known to dentists as peri-implantitis. Peri-implantitis is characterized by inflammation of the tissues surrounding the area where the implant is placed. Peri-implantitis can also appear as a secondary infection later as a form of periodontal disease that can lead to inflammation, bone loss, and even failure of the implant itself. As the infection can occur months or years after surgery, it is the dentist’s responsibility to review the patient annually.

 

3) Post Surgical Bleeding — Bleeding following the surgery is normal and should even be expected for about 1-2 days. Biting on a gauze placed over the surgery area for 30 minutes should stop the bleeding. Excessive bleeding is not normal, so you should inform your dentist if you have concerns after a few days. Don’t wait till it’s too late

 

4) Damage To Surrounding Tissues — Dental implant complications related to surgical errors affecting adjacent teeth, nerves or sinus are correlated with the experience and skills of the operating dentist or surgeon. An experienced implant dentist can identify potential problems by examining x-rays or CT scan, design the proper surgical plan and execute it successfully. Still, human make mistakes. Taking such necessary precaution is necessary.

 

5) Rejection – Though this has been cited in the research literature, it is an extremely rare complication. The dental implants can at times be viewed as a foreign body, and the body rejects it.

 

6) Unusable Dental Implants – This is in cases where an implant which has successfully integrated with bone, but the area or extreme angle of placement deem it un-restorable. So the implant ends up being unusable in the end.

the main components of this all kinds of sensor are the emitter, detector and the Retro-reflector Nagano keiki Pressure sensor . The emitter and the detector are in abs speed sensor the same package. The Retro-reflector is placed little far from the sensor. The light from the emitter is reflected off the Retro-reflector and detected by mazda 6 suction control valve . When the target passes between the suction control valve and Speed Sensor the Retro-reflector the beam is not reflected back to Pressure Sensor . Here the problem can be that the beam could reflect from the target itself. For this the polarising filter is used in the sensor. Pressure Switch
