Abutment Selection Flashcards

Question

Implant Provisionalization: Advantages

Answer 1

* restore esthetics & function * extended period of use (Bone graft) * patient exerpience prosthesis before final restoration (expensive)

Answer 2

* Fixed Provisionals * Bonded bridge * “Ribbond or Everstick” * Temporary Fixed Bridge * Immediate Implant provisionalization * Temporary Implant retained provisional * Removable Provisionals: * Removable Partial Denture (RPD Flipper) * Complete denture * Essix retainer

Answer 3

* Fixed: * more comfortable * well tolerated * show how final prosthesis will look and feel * less bulky * Removable * Remove at night * Bulkier

Answer 4

* Framework=Ribbond (Fiberglass) or Everstick * Advantages: * No transmucosal loading * Disadvantages: * requires special materials * Can't replace \>1 anterior tooth * Weak bond in: * wear cases→ due to lack of enamel * poor isolation * Can't use if: * Deep Bite * crowned adjacent teeth

Answer 5

* aka Tooth Supported Temporary Bridge * Advantages: * No Transmucosal loading * More resistant to dislodgment * Disadvantages * Have to prep adjacent teeth * Prepped teeth cannot be finalized until the implant is ready to be restored

Answer 6

* Provisional placed immediately after implant placement * take tooth and hollow out→use as shell * Keep out of occlusion * can't use w/parafunctional habits

Answer 7

* Fixed Provisional * Mini Implants=Temporary Implants * holds temporary prosthesis * don't osseointegrate→ Easily Removed * Advantages: * takes the load off definitive implants * Disadvantages: * added expense * High stress area=Fracture

Answer 8

* Removable Provisoinal * tissue supported * Advantages: * cheap * convert to fixed temporary after implants are healed * if satisfactory=index for final prosthesis * Disadvantages: * Transmucosal loading * Bulky * Psychological trauma

Answer 9

* teeth supported * No Transmucosal Loading * Disadvantages: * Breaks easily * Altered speech at beginning * Don't use when eating

Answer 10

* Cement Retained Provisional * Screw Retained Provisional

Answer 11

* Temporary Abutment * Plastic Gasket “Coping” * Advantages: * More esthetic * Disadvantage: * can't use with Short Abutment * limited inter arch space * Excess cement in sulcus

Answer 12

* No Abutment * Advantages: * Better for Limited Interarch space * Disadvantages: * No Angled Implants=Facial access hole

Answer 13

* after osteointegration * record all dimensions accurately * easier than natural teeth * but Less forgiving (No PDL)

Answer 14

* Aka Implant fixture screw or cylinder * part of implant in bone

Answer 15

* transfer implant position to cast * used during impression

Answer 16

* Implant replica * used on the cast

Answer 17

* Increase stress * No PDL→ Never neutralized * prevent complete seating of restoration * Complications: * biological→ Bone Loss * Mechanical→ Screw Loosening

Answer 18

* **_Implant Level (deeper)_** * High Esthetic cases * Anterior Implants * Recreates gingival tissues * uses resin * Types: * **Open Tray** (Direct Coping Transfer) * Splinted vs Non-Splinted * **Closed Tray** (Indirect Coping Transfer) * **Customized Impression transfer technique** * **_Abutment Level (shallower)_** * use w/Solid Abutments * final abutment delivered and temporized * allows for healing to go ahead and start * Impression coping “clicks” onto abutment * Types: * Direct * Indirect * Digital Impression

Answer 19

* Implant level impression (Deeper) * **Direct Coping Transfer** * pick-up impression * Coping: * long retaining screw that goes through tray * unscrew when impression material set * Limits: * hard to seat inside mouth so that screw goes through hole * Posterior region (more difficult) * _Non-Splinted:_ * Copings: Not Connected * Limits: * Movement→inaccurate relationship of implants * _Splinted:_ * Copings: Connected w/resin or composite * Limits: * time consuming * technique sensitive * Material shrinkage

Answer 20

* Implant Level impressoins (Deeper) * **Indirect Coping Transfer** * Limits: * Transfer process: * incorrect orientation * inaccuracies

Answer 21

* Implant level impression * Modified open tray impression * **Esthetic Zone** * better emergence profile & soft tissue contours * Anterior Teeth emergence profile * supports soft tissue→ Superior esthetics * Rapid Tissue collapse after temporary crown is removed

Answer 22

* transition from circular implant diameter to restoration contours * “Running Room”

Answer 23

1. Unscrew Temporary Restoration 2. Screw Temp on analog 3. Place Temp/Analog in plastic cup filled with Bite Registration 4. Remove temporary (analog stays in bite registration) 5. Connect Impression Coping to Analog 1. fill gap b/w bite registration and coping w/autopolymerizing acrylic resin 6. unscrew customized impressions coping from analog 7. Seat Impression coping on implant intra-orally 8. Take impression

Answer 24

* Closed Tray Impression Technique * use with **Solid abutments** * Final abutment is delivered & temporized * allows healing to go ahead and start * Impression coping “clicks” onto abutment * Limits: * Prefab abutments can't be used with: * severe implant angulation * Deep implant platforms * Direct vs Indirect

Answer 25

* 2004 * coded healing abutment * provides 3D info on implant location to: * adjacent teeth * opposing dentition * soft tissue * Scan Body

Answer 26

* translates implant position to digital file * same fxn as impression coping * require intraoral scanner (IOS) to collect data (point clouds=3D coordinates)
