Dental bridge

A bridge is a fixed dental restoration (a fixed dental prosthesis) used to replace one or more missing teeth by joining an artificial tooth definitively to adjacent teeth or dental implants.

Definitions

Fixed bridge: A dental prosthesis that is definitively attached to natural teeth and replaces missing teeth.

Abutment: The tooth that supports and retains a dental prosthesis.

Pontic: The artificial tooth that replaces a missing natural tooth.

Retainer: The component attached to the abutment for retention of the prosthesis. Retainers can be major or minor.

Unit: Pontics and abutment teeth are referred to as units. The total number of units in a bridge is equal to the number of pontics plus the number of abutment teeth.

Saddle: The area on the alveolar ridge which is edentulous where at least one missing tooth is to be reinstated.

Connector: Joins the pontic to the retainer or two retainers together. Connectors may be fixed or movable.

Span: The length of the alveolar ridge between the natural teeth where the bridge will be placed.

Resin bonded bridge: A dental prostheses where the pontic is connected to the surface of natural teeth which are either unprepared or minimally prepared.

Hall Technique

Image
The Hall Technique is a non-invasive dental treatment for managing decayed baby molars without the need for injections or drilling, significantly improving the patient's comfort. This method involves sealing the decay under preformed stainless steel crowns , aligning with modern, biologically-oriented dental care strategies. Notably preferred by children, parents, and dentists , this technique is backed by evidence demonstrating its effectiveness and acceptability, providing a more patient-friendly alternative to traditional fillings . Despite initial concerns about potential progression of sealed caries, long-term studies have shown that the Hall Technique can successfully arrest decay, reducing the risk of pain and infection associated with untreated carious teeth . Originating from the work of Dr. Norna Hall in Scotland, this technique simplifies the restoration of primary molars by cementing a crown directly over the decayed tooth without prior caries removal or tooth prepa...

Replacing multiple teeth with dental implant supported prostheses. Is that possible?

Replacement of multiple teeth follows generally the same process as replacement of one tooth. However, if two adjacent teeth are required to be replaced they can be supported on a single implant. The entire set of teeth in a jaw can be supported on a minimum of four implants, while in some cases up to […] Original post here: Replacing multiple teeth with dental implant supported prostheses.
