Anterior Bridge - Clinical Applications

Why Dentapreg Anterior Bridges?

Dentapreg® PFM strips are used for anterior bridge fabrication and serve as a bridge framework which is capable of carrying the loading from occlusion forces.  It is very easy to use and you don't need any special instruments or equipment as it is compatible with all light-curing composites. 

Dentapreg® Anterior Bridges may be done directly chair-side, semi-directly in the office, or indirectly in the laboratory.

Typical Clinical Situations:
- emergency provisionals
- short-term provisionals
- temporization during healing phase of the implant
- short to long-term temporaries to postpone the final treatment
- anterior bridge combined with perio splint

Benefits:
- non-invasive or minimally-invasive procedure (no prep of neighboring teeth needed -> less destructive treatment than conventional bridges)
- time saving (i.e. single visit bridges)
- low cost (no lab fees)
- repairable during service life 
- their versatility and unique mechanical properties allow for a wide range of solutions for specific clinical situations

 

Types of Bridges

With Dentapreg® PFM strips you can use different bridge retentions such as wing (Maryland Bridge), inlay, slot, or partial crown retention depending on the particular clinical situation. Thanks to the unique mechanical properties of Dentapreg® you can even use it for building a cantilever bridge or bridge with long spans. In order to obtain a dependable prosthesis you should follow the basic biomechanical principles of Dentapreg® bridges and instructions of use.

It can be combined with virtually all crown and bridge composites for creating pontics as well as used with natural coronal portion of the tooth.

Types of Pontics:
- a free hand pontic made from composite build-up material
- a prefabricated denture tooth with a groove cut into the lingual surface to fit over the Dentapreg® PFM strip (example of such a clinical case here and clinical video with instructions here)
- the original tooth with the root cut off and a groove cut into the lingual surface to fit over the Dentapreg® PFM strip

Types of Retention:
- wing retention (Maryland Bridge) - requires no preparation of neighboring teeth (unless the patient has a very tight bite in which case a minimal preparation of the ligual surface is necessary)
- inlay 
- slot
- partial crown prep

 

Implantology

A Maryland type bridge reinforced with Dentapreg®  PFM is a great alternative to traditional partial removable dentures ("flippers") during an implant healing period. It can take up to six months for an implant to settle in and conventional flippers used in this situation are not only unesthetic, but most importantly uncomfortable for the patient. The main advantage of a Maryland bridge built with Dentapreg® PFM is that it has extra-corronal retention and does not therefore require any preparation of the neighboring teeth. Such a bridge can be made either as a direct chair side procedure, or indirectly in a lab.
