| SEMI FIXED PROSTHESIS
For those with little bone tissue, but who need an implant, the dentists at the Cukon Dental Clinic suggest a solution with semi-fixed dentures on dental implants, also called semi-mobile dentures.
​
After the procedure in which the implants are inserted into the bone, our dentists put the attachments called locators or rods which connect the implants to ensure higher stability and support. At the end of this step, a semi-fixed denture gets placed onto the implants.
Maryland Bridges
​
The Maryland bridge is a method used to replace a missing tooth, without having to prepare the neighboring teeth.
A Maryland bridge consists of a metal framework with a porcelain tooth connected onto the front of the framework. The framework then ends up as a false tooth with one or two metal wings on the side. These metal wings are prepared to have a porous surface so that they can receive a bonding agent and then the wings are bonded to the back sides of the teeth on either side of the missing tooth.
The non-metallic option is zirconia, a material that mimics natural teeth due to its tooth colored appearance. The single retainer cantilever design from Zirconia ceramics has shown very good esthetics and strength.
Advantages of a “ Maryland bridge ”
​
-
Minimal tooth structure needs to be removed.
-
Abutment teeth are not damaged. They are basically left intact.
-
Because of the conservative nature of the preparaton, the potential for pulpal trauma is minimized.
-
Anesthesia is often unnecessary in order to prepare the teeth.
-
Less periodontal irritation results in comparison with the conventional bridge
Precision and Semi-Precision Attachments
​
Precision and semi-precision attachment dentistry allows for esthetic removable partial dentures that do not display the metal clasps that can make traditional removable clasped cast partial dentures unesthetic. The attachment itself becomes the clasp, rest, reciprocating and stabilizing element and is hidden inside the partial denture, which renders it invisible. The attachment also provides the retentive element necessary to retain the partial in the mouth at rest and during masticatory function (Figure 25-1). Attachments are also used in segmented fixed partial denture and overdenture prosthetics on natural roots and implants. There are two parts to the attachment: a male and a female. In planning a removable partial denture, one part is incorporated into the casting or root on the crown, bridge, or splint, and the other part is incorporated into the removable partial framework or acrylic. As a result, the partial denture becomes highly esthetic and appealing to patients. Esthetically speaking, from a patient’s perspective, they smile with confidence, knowing that they have functioning, beautiful, natural-looking teeth.
