CONTENTS n Patient History n Patient Condition and Background n Clinical Treatment Plan n Dental Technology Treatment Options n Dental Technology Procedures n References n Acknowledgements
Patient History n Bridge 12 -14
Patient Condition and Background n Root canal on 141 n Micro leakage in 14 n Lateral Periodontal Abscess formed 2
Clinical Treatment Plan (1 st phase) n 14 removed n 12 in good condition n Bridge separated
1 st Phase… n Tissue surgically sutured 1: Prevent - any infection - ulceration - exposed tissue Reasons for transitional denture n
Clinical Treatment Plan… (2 nd Phase) n Implants placed n Bone collector used n Stent used
Dental Technology Treatment Options n Available options: - Cobalt Chrome Denture - Acrylic Denture - Implant-Supported Crowns
Cobalt Chrome Denture (Kennedy Class 1 Mod. 1) n ADVANTAGES n DISADVANTAGES Excellent support n Durability n n n Expensive +/-R 1100 Discomfort Not suitable as healing appliance Must be well designed
Acrylic Denture 3 n ADVANTAGES n DISADVANTAGES Inexpensive +/-R 600 n Comfortable n n Must be cleaned regularly n Increased risk of fracturing
Implant-Supported Crowns 4 n ADVANTAGES n DISADVANTAGES Aesthetically pleasing n Excellent retention n Excellent support n n Very expensive
Left Untreated n Consequences n n n Drifting of teeth Aesthetics will degenerate Discomfort Lead to bad habits Maxillary arch will eventually collapse
Requirements of Ideal Prosthesis n Aesthetically pleasing n Comfortable n Durable n Financially viable n Conserve existing oral environment n Concluded: Implant-supported crowns are the best and chosen option
Implants n 2 Externally hexed implants used n Length 15 mm n Diameter 3. 75 mm
Dental Technology Procedures n Transitional acrylic denture - ball clasps between 25 and 26, 14 and 15
Dental Technology Procedure… (Standard procedure for temporary partial denture) n Wax-up done and ball-clasps positioned n Denture flasked n Heat cure denture material used n Cured n Deflasked and polished n Ready for placement
Dental Technology Procedures… n Stent made
