Cement- Retained Restorations
The cemented implants is defined as an intermediate element of cemented prosthesis (abutments), screwed directly on to the implants
Advantages
- Improved esthetics due to the compliance with the emergence profile
- The concrete sealant facilitates the passivation of the structure
- Easy Occlusal balancing
Screw Retained Restorations
The screwed implant is defined as an intermediate element of screwed prosthesis (abutments), in turn screwed directly on the implants and in some select indications screwed on to abutments too.
Advantages
- Easy disassembly of the prosthesis
- Connection through anatomical pillars
- No use of sealant cements
Attachment- Retained Restorations
There are several indications for overdenture treatment in connection with implant therapy. Functionally esthetics, phonetics and hygienic requirements in certain clinical situations require the use of overdenture as option of treatment with implants.
Indications
- An unfavourable jaw relation which makes treatment with a fixed bridge restoration difficult
- Esthetic problems, Eg: the need for lip support in the upper jaw
- Patients dissatisfaction with removable denture due to oral irritations and /or loss of bone for denture fixation
- Edentulous patients with a cracked palate
- Economic constraints
