Part 1 Quiz

Teeth with normal support respond to (jiggling forces) from occlusal overload with ?

• Resorption, repair, widened periodontal space and increased mobility

•   Resorption, wear, crown fracture and mobility

•    Resorption, widened periodontal space, mobility and sever pain

• Resorption, wear, muscle fatigue and pain

According to Gross article in 2008, for posterior fixed implant-supported restoration clinical guidelines, when working group function on posterior implant supported segment is selected, it is recommended to ?

•   Make the cusps very steep to allow for better separation in group function to reduce biomechanical risk

• Flattened the incisal guidance

• Flattened the condylar guidance of the articulator during the restoration fabrication

•   Flattened cusps and smooth even contacts in group function are desirable to reduce biomechanical risk

One of the following is not true regarding the occlusal guidelines for single implant prosthesis

• Light contact at heavy bite and no contact at light bite

• Centered contacts (1-1.5 mm flat area)

•   No offset contact

•   light proximal contact

In one of the assigned articles for this topic, it was recommended for Full-arch fixed implant prosthesis to use either one of the two types of occlusal scheme, mutually protected occlusion or balanced occlusion (occlusal balance).

What is your opinion about this recommendation?

• I totally agree with this recommendation

• I totally disagree with this recommendation

• I am not sure, but it could be acceptable

• I am not sure, but it could be incorrect

According to Carlsson article in 2009, he recommended the following for implant occlusion ?

• Mutually protected occlusion design for full-arch implant prosthesis

• Canine guided occlusion design if the canine is a natural tooth

• Group function occlusion design on posterior implant segment

• There is no evidence to recommend a specific occlusal design

Which one of the following is not considered as a warning sign of the implant failure:

•    Very slight implant mobility

•   Loosening or fracture of connecting screws or abutment screws

• Swelling or bleeding of peri-implant soft tissues

• Pain

One of the biomechanical complications of implant prosthesis overload is connecting screw fracture. This connecting screw mostly fracture at:

• The middle of the screw

• The head of the screw

• The level where the screw thread part ends

• The tip (end) of the screw
