Dental implants is one of the best tooth restoration techniques science has given us today. At one time dental implants could be afforded by rich and famous only but thankfully there prices have come so down that even a person with reasonably good income can afford to get dental implants fixed. Apart from money how many people think aout the problems involved with dental implants or the complication involved during fixing dental implants or post operation. What are the factors that affet the long term success of dental implants. Here is an insight into the problems involved  with dental implants , the complications and the factors affecting the long tem sucess of dental implants

Occlusion: Bone resorption around the dental implant can be caused by the occlusal trauma which occur by osteoclastic activity. In the natural dentition, bone remodeling occurs once the stress is eliminated but in dental implant system, it usually does not reform

Connecting a dental implant to natural teeth

Connecting a single implant to one natural tooth with a fixed partial denture can create excessive forces because of the imbolity of implant, compared to functional mobility of a natural tooth. Potential problems with this type of restoration include: 

  1. Breakdown of osseo integration.
  2. Cement failure on the natural abutment.
  3. Screw or abutment loosening.
  4.  Failure of implant prosthetic component.

Dental Implant and Framework Kit

Pathogenic forces can be placed on dental implant if the framework does not fit passively. The fit of dental implant framework should be checked, No visible amount of space or any amount of movement with finger pressure should be there on any of the other implant abutments.

 

Shock Absorbing Elements

 

Because there is no movement between the bone and dental implant, incorporating some type of shock – absorbing layer to reduce occlusal implant forces may be necessary. This shock may be specially designed into the dental implant system, or the occlusal surface of restoration..

 

Maintainence of Dental Implants

 

The goal of dental implant maintenance is to eradicate microbial populations affecting the prosthesis. Proper and timely home care measures for prolonging the life time of Dental implant is most effective. Recall visit should be scheduled at least every 3 months during the 1st year. The patient’s oral hygiene should be evaluated and documented at a racall visit. Sulcular debridement should be performed with plastic or wooden scalers, since conventional instruments will scratch the titanium. Abutment should be polished with rubber cup and tinoxide. At each recall, dental implant mobility should be evaluated; any bleeding after probing should be examined. Frame work fit and occlusion must be checked.

Complications of Dental Implants

  1. Bone loss
  2. Inappropriate size and shape of dental implant.
  3. Inadequate number or positioning.
  4. Poor quality.
  5. Compromised healing phase.
  6. Inadequate fit.
  7. Improper design of prosthesis.
  8. Excessive occlusal forces .
  9. Inadequate oral hygiene.
  10. Systemic influence( tobacco use or diabetes.)
