greater than or equal to 90%
What are the 3 main types of dental implants?
subperiosteal
transosteal: supports mandibular denture in pts with severe bone resorption
endosseous: MOST COMMON; it is more successful in the mandible due to denser bone
Which type of implants are surgically placed in the bone and are the most popular type of implants?
endosseous
What are the 2 most commonly used metals in endosseous implants?
titanium and titanium alloy
What are 3 reasons why titanium and titanium alloys are the most common metals used in endossious implants?
favorable biocompatibility with oral tissues
light-weight
corrosion-resistant
What material is used when need parallel of multiple implnts; for correct anbulation of implants? (surgical 2 stages)
acrylic STENT (guide)
What will happen in surgically placing an implant if excessibe heat is generated during drilling in the bone?
the bone can be damaged and will not integrate with the implant cylinder (or fixture)
What is a risk with the immediate-placement surgical procedure?
the implant is placed immediately into the fresh extraction site; and it causes loading of the implant under chewing forces before the bone shows healing around the implant, which may cause the implant to loosen and be lost
true or false. Although no connective tissue fibers (PDL or JE) are connected to the implant surface, close adaptation and attachment of ths sulcular epithelium to the implant surface are noted
true
What helps to develop a biological seal that prevents microorganisms from invading the tissues around dental implants?
