  2. Concept Objective Key Point Goal • To acquire basic knowledge of each type of implant prosthetic. • To look over overall implant prosthetics. - To understand each type of implant prosthetic. • Screw retained restoration. • Cement retained restoration. • Combination type retained restoration. www.befrest.com

  3. Contents • 1. FAQ • 2. Contents for education • Classification of implant prosthetics • Feature of each type of implant prosthetic • Terminology • Quiz www.befrest.com

  4. 1. FAQ • What is a difference between implant prosthetic and prosthetic for natural teeth? • Root – Fixture • Prepped tooth – abutment • Nerve – can’t sense prep www.befrest.com

  5. I. Classification of implant prosthetic Classification based on shape of abutment. Classification based on connection type. www.befrest.com

  6. I. Classification of implant prosthetic 1. Classification Upper structure (Prosthetic) • classify by shape of abutment: • - Screw-combinedabutment. • - Screw-separatedabutment. Crown Abutment • classify by connection type of upper structure: • - Screw retained restoration. • - Cement retained restoration. • - Combination type restoration. Artificial root of tooth (fixture) www.befrest.com

  7. I. Classification of implant prosthetic 2. Classification by shape of abutment (1) Screw-combinedAbutment: one body type abutment that body of abutment is combined with screw which connects to fixture. Body screw www.befrest.com

  8. I. Classification of implant prosthetic (2) Screw-separatedAbutment: The abutment and the screw are separated in 2 pieces. Body screw www.befrest.com

  9. II. Understanding of implant prosthetic 2. Classification by connection type • (1) Screw retained restoration (Screw type): • : Connects crown & abutment with screw • Oral • Crown + Screw • Loading prosthetic Resin Fill Fixture Crown Screw www.befrest.com Hole Fill + 

  10. II. Understanding of implant prosthetic (2) Cement retained restoration (Cement type): Cement crown withcement material. • Oral • Crown Loading prosthetic Fixture + Abutment Crown Hole Fill www.befrest.com Cementation +  Cement

  11. II. Understanding of implant prosthetic • (3) Combination type restoration (ER type): • Screw Cement retained restoration. • Crownis cemented to abutment by cement material for fixation and connecting / disconnecting to/from fixture by screw. • Oral • Crown Loading prosthetic Fixture Crown Resin Fill Screw Hole Fill www.befrest.com +  Cement Cementation between ABT and Crown

  12. II. Feature of each type of implant prosthetic • Screw retained restoration (Screw type) • Cement retained restoration (Cement type) • Combination retained restoration (Combination type) www.befrest.com

  13. II. Feature of screw-retained implant prosthetic 1. Screw retained restoration Connecting combined crown and abutment to fixture. connecting screw. Filling screw hole with resin. Resin block out. www.befrest.com

  14. II. Feature of screw-retained implant prosthetic ◆ RealCase (GoldCast ABT. single)  One body type Abutment connects to fixture by screw. Connecting pick-Up type Imp. coping to the fixture Connecting ABT to stone model Impression PutLab analog in impression Trimming ABT Wax Up Casting Completed prosthetic Loading a Crown onto ABT Screw tightening Screw hole fill www.befrest.com

  15. II. Feature of screw-retained implant prosthetic • advantage: • Repair and maintenance are easy due to easy removal. • Inflammation from use of cement does not happen. • Easy to solve prosthetical problems. • disadvantage: • Wearing down occlusal surface requires repairing and replacing. • Building aesthetic occlusal surface is complicated due to screw hole on the occlusal. • Requires high technique. • “Passive Fit” is tough in bridge case. • Non-applicable to anterior which requires aesthetic. www.befrest.com

  16. II. Feature of screw-retained implant prosthetic ◆ disadvantage of Screw-retained type prosthetic • Exposure of Screw hole. •  Unaesthetic • block out resin andPorcelain could be damaged. www.befrest.com

  17. II. Feature of each type of implant prosthetic ◆ Line-up of Screw type Abutment GoldCast ABT. NP-Cast ABT. ZioCera ABT. Convertible ABT. Multi ABT. Multi angled ABT. www.befrest.com

  18. II. Feature of each type of implant prosthetic 2. Cement retained restoration Applying cement to inner surface of crown. Connecting crown to Abutment. Removingresidual Cement on the margin of crown. www.befrest.com

  19. II. Feature of cement-retained implant prosthetic ◆ RealCase(Rigid ABT. 3 bridge)  Crown is cemented to abutmentby cement material. Impression Impression material Connecting ABT to fixture Capping Rigid Imp. Coping www.befrest.com Sticking lab analog to impression material stone model Capping burn-out cylinder Wax Up casting Completed prosthetic Cementation Cement crown onto fixture

  20. II. Feature of cement-retained implant prosthetic • advantage: • Same process with natural teeth prosthetic. • Creating functional and esthetical occlusion surface is possible. • (No screw hole) • Easy to get “Passive Fit “. • It is less influenced by path. • disadvantage: • Difficult to repair and do maintenance. • Hard to remove leaked cement materials. • Leaked cement material to gingiva could cause inflammation. www.befrest.com

  21. II. Feature of cement-retained implant prosthetic ◆ disadvantage of Cement-retained type prosthetic  Difficulty to remove leaked cement. • Inflammation on gingiva www.befrest.com • Peri-implantitis

  22. II. Feature of cement-retained implant prosthetic ◆ Cement-retained typeabutment Line-up FreeForm ST ABT. Transfer ABT. Angled ABT. ZioCera ABT. Rigid ABT. www.befrest.com

  23. II. Feature of each type of implant prosthetic Fill Screw hole. 3. Combination type restoration Apply cement. Capping crown to abutment. Removingresidual cement. disconnecting Screw. www.befrest.com Puling out crown cemented to abutment. Removing cement around margin. Connecting cemented ABT with crown. connecting Screw. Fill screw hole. Resin block out.

  24. II. Feature of each type of implant prosthetic ◆ Realcase (ER ABT. 3 bridge)  Crown is first cemented toabutmentwith cement materialand cemented prosthetic (Crown+ABT) will be connected to fixture by screw. Connecting Pick-Up type Imp. Coping to fixture Impression StickingLab analog to impression material stone model www.befrest.com Completed prosthetic Trimming ABT. Wax Up Casting Cementation Capping crown and plugging screw hole Connecting ABT to fixture Removing Cement

  25. II. Feature of each type of implant prosthetic • advantage: • Repair and maintenance are easy due to easy removal. • Inflammation from use of cement does not happen. • Good passive fit in a bridge case. • Applicable to multiple case. • disadvantage: • Wearing down occlusal surface requires repairing and replacing. • Building aesthetic occlusal surface is complicated due to screw hole on the occlusal. • Non-applicable to anterior due to path-related problem. www.befrest.com
