IMPLANT DENTISTRY EXAM I - 8180 QUESTIONS ANSWERED CORRECTLY LATEST UPDATE
2025/2026
What is a dental implant? - Answers - An alloplastic material or device that is surgically placed
beneath the mucosal or periosteal layer and on/or within the bone to provide retention and
support for a fixed or removable prosthesis
T/F
The first dental implants were pieces of shell placed into extraction sockets in 600 A.D.
Implants placed due to tooth removal due to caries have a better prognosis than teeth removed
due to perio disease. - Answers - True
- True
What are the 3 main implant classifications? - Answers - Morphology
- Constituent material
- Position: subperiosteal, transosseous, endosseous
Why are subperiosteal implants so difficult? *Where are they indicated?* - Answers - Tissue
must be flapped prior to impression being taken for bone contours; framework is then made,
then the tissue must be flapped again for placement
- Meant for highly resorbed mandibles - these require extensive restorative space
Why are transosseous implants not often used anymore? - Answers - They require an incision to
be made through skin to the inferior portion of the mandible - extensive surgery
What are the three types of endosseous implants? Which do we typically use today? - Answers -
Blades
- Cylinders
- *Screws*
T/F
Blade implants show a significantly lower number of failures. Bone staple implants show very
high success rates after 5 to 10 years. - Answers - False: they show a significant number more
failures
- True: due to osteointegration
What are the 5 and 10 year success rates for subperiosteal, blade, and bone staple implants? -
Answers - *Subperiosteal*: 60-90% at 5 years, 36-64% at 10 years
, - *Blade*: 42-66% at 5 years, 40-50% at 10 years
- *Transosseous*: 93% at 5 years, 86% at 10 years
Who coined the term "osseointegration"? What is this? - Answers - Professor Branemark in 1951
- When titanium integrates with bone
Endosseous root form implants were introduced by _________ in 1955. The first clinical trial was
begun in _______. - Answers - P.I. Branemark
- 1965
What is osseointegration? What are some variables of this? - Answers - A direct, structural, and
functional connection between ordered, living bone and the surface of a load carrying implant at
the level of light microscopy
- Biocompatibility, macro and micro structure, surgical techniques, time of loading, state of
hosting bone
T/F
Osseointegration is technique sensitive and subject to host variables. As we increase in
titanium grade, the tensile strength decreases. - Answers - True
- False: it increases as we increase in grade; however, the oxidizing qualities decrease
Nobel Implants are Grade ____ titanium. Straumann are Grade ____ titanium. - Answers - Nobel:
Grade 1
- Straumann: Grade 4
T/F
Success rate shown by many studies for endosseous implants is > 95%. Mandibular implants
are more successful than maxillary implants. - Answers - True
- True
List the location of endosseous implants from most to least successful as quoted by Dr. K. -
Answers - Anterior mandible
- Anterior maxilla
- Posterior mandible
- Posterior maxilla
- Grafted areas
