Question 28

Healing abutments 2 things

Answer 28

Cover screws Transmucosal (tapered,conical, ovoid)

Question 29

Cover screw characteristics

Answer 29

Submerged healing Avoid soft tissue to proliferate in the implant connection Color coded Different heights It is removed at the 2nd stage surgery or uncover surgery

Question 30

T/F: you torque cover screws

Answer 30

False - NEVER torqued, can strip screw head

Question 31

Transmucosal (tapered,conical, ovoid) characteristics

Answer 31

Maintains an opening through the soft tissue during treatment, allowing easy access to the implant Not useable to make the final impression Help in initial tissue shaping - can add composite for custom healing abutment Comes in different heights and widths Placing a larger healing abutment helps the restorative dentist (soft tissue management)

Question 32

T/F: Transmucosal are torqued

Answer 32

False - never torqued

Question 33

T/F: stocks are prefabricated abutments and cannot be modified

Answer 33

True

Question 34

Stock characteristics

Answer 34

Cement retained restorations Screw into the implant body Less expensive and easier for the lab

Different types of stock

Answer 35

Straight Angled Anatomic Ceramic

Question 36

Custom abutments characteristics

Answer 36

Allow Anatomic design of the abutment Cement retained restorations and screw retained restorations Custom designed for final restoration

Question 37

Why are custom abutments more expensive

Answer 37

Gold cylinder + metal allow

Question 38

CAD/CAM fabricated custom abutment

Answer 38

Milled from titanium

Question 39

Angle abutments characteristics

Answer 39

Correct implant angulations Usually associated with multi unit restorations Screw or cement retained Different angle correction Different heights

Question 40

Precision attachments (overdentures) self aligning attachment system (locators)

Answer 40

Unsplinted Resilient dual retention system

Question 41

Precision attachments most common complications

Answer 41

Dull insert Lost of retention over time Dislocation of metal housing

Question 42

Answer 42

Stock Angled

Question 43

Analogs/replica-laboratory use Implant (fixture) level

Answer 43

Tissue level Bone level

Question 44

Open tray

Answer 44

Require modification of the tray Need to make sure impression material does not get locked into the access Allows for verification jig (splinting of multiple implants)

Question 45

Short vs long open tray
