Study Notes

Treatment Options for Edentulous Areas

  • The first question to consider when treating an edentulous area is why not a dental implant, considering factors such as medical history, bone amount, and other teeth.
  • Implants may be the best option depending on the circumstances, and it's essential to rule out implant placement before considering other alternatives.

Partial Dentures

  • A partial denture may be an option, but its stability may be questionable, especially if it relies on clasps.
  • Even with clasps, the stability of a partial denture may not be sufficient.

Implant-Supported Overdentures

  • An implant-supported overdenture is an option, involving extracting all remaining teeth except for the implants.
  • This option is not a natural tooth-supported overdenture.

Treatment of Peri-Implantitis

  • Peri-implantitis is a condition where bone loss occurs around a dental implant, and detoxifying the implant surface is necessary.
  • Methods for detoxifying the implant surface include:
    • Plasti surgery: using a high-speed bar to remove roughened surfaces and exposed threads, while generating a lot of heat and titanium particles.
    • Powder abrasion
    • Ultrasonics
    • Non-metal curates
    • Citric acid
    • Chlorhexidine
    • EDTA
  • The effectiveness of these methods varies, and there is no clear evidence of which one is superior.

Restoration Options

  • The choice of restoration option can have consequences, and it's essential to consider these consequences.
  • Common causes of denture-related problems include alveolar ridge resorption, which can be difficult to treat.

Detoxifying the Implant Surface

  • Detoxifying the implant surface is crucial before placing a bone graft or treating the defect.
  • A titanium brush can be used to clean the implant surface, removing toxins and poisons.

Implant Surface Modification

  • Companies like Strom and Nobel Biocare are working on modifying implant surfaces to make them more biocompatible and effective.
  • These modifications can improve the stability of the implant, with some getting similar results in a shorter time.

Detoxification and Bone Grafting

  • Detoxifying the implant surface can be done using various methods, including titanium brushes, saline, tetracycline, and EDTA.
  • After detoxification, a bone graft can be placed to promote additional bone growth.

Real-World Case Study

  • A patient came in for a second opinion after being recommended to extract all their remaining teeth and get a denture.
  • The patient was given an alternative option of placing two implants, which didn't take long and provided a stable solution.
