Dental Treatment of March 2015

Final Delivery for crown. Existing partial upper denture is not shown in this x-ray. Final Delivery for crown. Existing partial upper denture is not shown in this x-ray.
Case of March was a case that required high precision and collaboration among the dental lab, the patient, and the clinician. Due to confidentiality, I decided not to disclose some of the information in this case. 

The case involved a patient with a large amalgam on tooth #2 that had recurrent decay. Tooth #2 was an abutment with rest seat for an existing partial upper denture (PUD) that replaced some front teeth. Therefore, any new restorations must be retrofitted to the existing PUD, otherwise the new PUD is required. Typical procedure would require a final pickup impression, and the dental lab would hold on to the existing PUD for the duration of the fabrication (one to two weeks), in order to retrofit the new crown to the existing PUD. 

However, patient is highly depended on the existing PUD for confidence and without PUD to replace the missing front teeth, it would be devastating to patient's social life. Due to this special situation, I communicated with our local PreTech Lab technician to make special arrangement for patient. The lab technician agreed to give priority to the fabrication of the master cast and give the existing PUD back to patient the same day; but the patient must also visit the PreTech again when the lab technician would be layering the porcelain. Because PreTech is a local dental lab that is only 10 minutes away, this arrangement was feasible. 

A crown fabricated to retrofit an existing partial denture requires extraordinary precision and skill in comparison to a typical crown without existing partial denture. Not only must the inner surface fit to the tooth preparation, the outer surface of the crown must also fit to the existing PUD. Because this PUD has a flexible retentive clasp for retention, and so, the high of contour and amount of undercut must fit both the reciprocal clasp, the retentive clasp and the guide plane.  

The final delivery of this case was a success. Careful adjustments were needed during the delivery appointment as expected. Nevertheless, our patient was happy and satisfied. Kudos to PreTech for the special arrangement which made this case possible.

Case of February 2015

Before and After Dental Treatment
Original fractured tooth
Fracture to both central incisors. Patient's chief concern is esthetics and then replace the missing upper teeth. Existing large composite on both central insicors. Best option would be all-tooth-colored crowns (emax) for longevity and esthetics. Follow up with upper partial denture.

Choosing the correct color for the tooth
Shade is chosen by Vita 3D Master Shade guide, which offer superior representation of color space. Because centrals were darker due to existing fillings, we decided to use the shade of adjacent teeth. 

Temporary dental crown - AKA Provisional Crowns
Provisional (temporary crowns) were fabricated in house. The provisional was actually a single piece, connection both central incisors together, instead of two separate provisional crowns. Connecting the two units offers improvement on retention and strength. The esthetics of provisional crowns is usually more challenging, especially when the units are connected together; sufficient embrassure (space near the contacts) must be created to give the illusion of two separate teeth. 

Final dental treatment
Our lab technician was very skillful. Date of delivery was uneventful, and patient was very pleased by the result. Future plan include the replacement of upper teeth with upper partial denture.
