Biologic complications

Extraction of teeth with persistent periapical lesions requires a specific drilling protocol to remove infected bone, to reach healthy trabecular bone and start up a bleeding. Residual dens sclerotic bone may harbor latent pathogenic microorganisms for a...

Framework materials

A commonly used option for fixed restorations is a metal or zirconia framework with ceramic or acrylic veneering. The amount of alveolar bone resorption determines whether teeth or teeth and soft tissue must be replaced...

Cement-retained restorations, overview

Cement-retained restorations are a traditional design to attach a restoration (crown, bridge) to an implant-retained abutment, similar to cementing a crown or bridge restoration on a natural tooth. With the traditional, relatively...

Veneering with Acrylic

Frameworks are veneered with veneering materials, to design the esthetics and shape of the definitive restoration. Framework material options for acrylic veneering include titanium, (CrCo) Cobalt - Chrome and precious alloys...

Veneering with Ceramic

Frameworks can be made from titanium, zirconia, precious alloys and Co-Cr base alloys and can be cement-retained or screw-retained. With minimal bone resorption, a ceramo-metal restoration is preferable to accommodate interarch...

Abutment materials

Implant-based prostheses can be cement-retained, screw-retained or a combination of both (Fig 1). By definition, an abutment is a component that is intermediate between the implant and the restoration and it is usually screw...

Direct to implant vs. abutment

Advantages of abutment-supported prostheses are 1) When implants are not parallel to each other, the use of angulated abutments can "correct" for the non-parallelism 2) Angulated abutments are available for a screw-retained prosthesis and 3) Custom abutments can be...

Choice of implant

The majority of commercially available implants are variations of Brånemark’s original design of a screw which he coined as 'fixtures'. This has been the starting point for numerous current market variations that incorporate convergent themes of implant material...
