Screw Application in Dental Prosthesis

Indications for use of screws in Prosthetic Dentistry:
1. The main indications are the connections of abutments and the construction of functional dental prosthesis.
2. Where a conventional fixed dental prosthesis cannot be constructed, screws can be employed to connect parts of the denture to in the mouth, thereby forming a functional fixed dental prosthesis.
3. Screw assemblies may be used to allow the prosthesis to be removed by the dentist. This can be useful in planning ahead.
4. Because dentist can remove the dental prosthesis, it is possible for him to examine the area underneath the pontics to prevent inflammation. Repairs are also simplified.
