12 - Implant restoration Flashcards
What are the types of implant retained prosthesis?
- removable (stud, bar, magnet)
- fixed (single, multi-unit, full arch)
What are the different types of over denture attachment?
- retentive ball
- LOCATOR (silicone)
- bar
What are the different types of fixed implant prothesis?
- screw or cement retained
- single, multi-unit or full arch
What are the purpose of provisional crowns?
- to provide patient with aesthetic result in interim
- gingival moulding and maturation for final impression
How long should provisional crowns be placed on implants?
2-3 months
What are the different types of implant impression?
- open tray
- closed tray
What is the open tray implant impression technique?
- impression coping screwed into implant
- impression tray is modified to have access hole over implant area
- impression taken over top of coping
- coping unscrewed after impression set
What is the closed tray implant impression technique?
- impression coping friction fitted to implant
- impression taken over coping
- coping removed from implant with impression
What are the benefits of an open tray implant impression?
- safer as screw retained
- one piece
- adjustable
What are the benefits of a closed tray implant impression?
- no additional preparation of tray
- cheaper
- easy to snap on
What impression material should be used for implants?
- impregum
- rigid so removes implant coping
What complications are associated with screw retained implants?
- technical
- porcelain fracture (hole for screw weakens crown)
- screw fracture
- screw loosening
What complications are associated with cement retained implants?
- biological
- peri-implant tissue inflammation due to excess cement
What are the factors in the pink aesthetic score?
- mesial papilla
- distal papilla
- soft tissue level
- soft tissue contour
- alveolar process deficiency
- soft tissue colour
- soft tissue texture
How far apart should adjacent implants be?
- 3mm
- prevent bony necrosis
