Unilateral Fixed Partial Denture

A lower Unilateral Extension Fixed Partial Denture was fabricated with the purpose of restoring the center of occlusion, and create a premolar occlusion. The Cantilever Fixed Partial Denture design will also provide functional stability for the complete denture on the upper. It will also protect the anterior part of the maxillary ridge from excessive load or resorption.

Minimal occlusal preparation was done on both premolars. Selective grinding on maxillary denture was done to obtain balanced occlusion in the muscular contact position.

Segmented Fixed Partial Denture

A lot of times, we do long Fixed Partial Dentures for cases which are indicated for RPD. This is due to patient’s demand and his/her willingness to pay for fixed prostho treatment.

Long Fixed Partial Denture

Common problems with long fixed bridgework are inaccuracy of the final restoration due to cast errors, problems with non parallel abutments and difficulty to repair.

You may decide not to do it, but the dentist next to your office will do it anyway. So why not do it?

But instead of a long bridge, a Fixed Partial Denture can be done for such cases by segmenting it. By using attachments, segmented FPD can be done for the patient.

Dental Screws in Dentures

Screw Retained Denture

To overcome problems in Prosthodontics, dental screws can be used. Screws may permit combination of advantages of fixed partial dentures and removable partial dentures.

A Fixed Partial Denture is the restoration of choice where the edentulous area is small. But the problem of malaligned abutment results to too much tooth tissue to be removed to the extent that inadequate retention is achieved. Dental screws can be used where the restoration is made in two parts and secure these parts with Dental Screws.

Screw retained Dental Prosthesis allows damaged pontics be removed and modified. Screws facilitate routine maintenance as the area under the pontics can be examined by unscrewing them.

Fixed Partial Denture : Implant Angled Abutments

While tightening the abutment screw, correct position of the Dental Implant Angled Abutments for fixed partial denture is maintained by doing this procedure: A silicone putty index may be made from the master cast, placed palatally and grooved by a guide-pin, reduced in length to 2 threads and placed in the hole for the gold screw. This guide pin may then be used to support the abutment firmly in place while tightening the abutment screw.

Metal Ceramic Dental Bridge

Metal Ceramic Dental Bridge was made for a 22 year old male patient. Missing teeth are 11 and 21 FDI Two-Digit Notation or upper right central incisor and upper left central incisor. Tooth numbers 12 and 22 FDI (upper right lateral incisor and upper left lateral incisor) were prepared as abutments for the 4-unit Porcelain Fused to Metal Fixed Partial Denture.

All Ceramic / Alumina Dental Bridge

All Ceramic Dental Bridge / Alumina Dental Bridge is esthetically superior than Porcelain Fused to Metal Crown & Bridge. With all ceramic materials, metal associated allergic reaction by the patient is eliminated. Sensitivity level to cold and warm is also reduced. Long term esthetics is also achieved because they are biocompatible, thus all ceramic dental bridge integrate better with surrounding soft tissue. Alumina, aluminum oxide, is amphoteric oxide of aluminum. Alumina is more transluscent than Zirconia.

Alumina Dental Bridge

4-Unit Alumina Dental Bridge which was fabricated to restore missing teeth, 11 and 21, FDI Two-Digit Notation, upper right central incisor and upper left central incisor.

Crown and Bridge

Eight-year-old Porcelain Fused to Metal Crown and Bridge which exhibited marginal breakdown, asymmetric gingival form and ridge lap pontics.

Dental Implant Body

A good implant body should offer high initial stability, bone condensing property and allow optimal placement flexibility. It should offer less traumatic treatments and options for patients with compromised bone situations.

Alumina Fixed Partial Denture

Alumina Fixed Partial Denture or all ceramic crown and bridge / restoration is significantly more esthetically pleasing than porcelain fused to metal (PFM) restorations. Gray line that is often visible under PFM crown and bridge is eliminated in all-ceramic restoration. All-ceramic substructure preserves the luminosity of the underlying remaining tooth resulting in more natural appearance, as compared to PFM crown and bridge.

Under very bright light, Porcelain Fused to Metal FPD shows shadow effect from the metal.
