Introduction/Context/Diagnosis

Digital dentistry is slowly and gradually becoming the new face of esthetic dentistry. Application of digital dentistry gives a slight edge over the conventional approach in relation to taking impressions for multi-unit bridges. Review of recent literature has shown that when Digital impression is taken for multi-unit crown preparation, the digital impression has a slight edge over the conventional impression regarding the interproximal & marginal fit. Digital impression also considerably reduces the treatment time in relation to impression taking and is more convenient for the operator and more comfortable to the patient.

Methods/Treatment Plan

Introduction

A 43- year old female patient visited the dental clinic with the chief complain of wanting to restore her missing anterior teeth using fixed prosthetics options. The patient had an accident due to which she had fractured her tooth #9 (Horizontal fracture at the gum level) and severely traumatized tooth #8 (Grade II mobility).

Procedure

The patient was presented with the options of Implants and fixed prosthetics bridge. The patient decided to go for the option of a conventional bridge in place of implants because of economic reason and time factor. Maxillary anterior central Incisors (8 & 9) were extracted due to poor long-term prognosis. The patient had an edge to edge bite. The decision was made to extend the bridge from canine to canine on both sides with the canine & lateral incisors being double abutted. The material chosen for this procedure was layered zirconia because of its inherent strength for long-span bridges and good esthetic details. The wax-up was done, and the case was presented to the patient and faculty to show the expected outcome. The splint was prepared using wax-up as the base for the fabrication of temporary crowns. Bis-bake acrylic try-in was done to determine the final fit. After, this the framework was sent to the lab for the final porcelain firing.

Results/Outcome

Patient loved the outcome of the result. The patient reported stable occlusion in all excursive movements.

Significance/Conclusions

These long span bridges can be challenging in fabrication as well as in terms of long-term prognosis. The prognosis of these bridges depends upon several factors such as the compliance of the patient to maintain oral hygiene, the choice of material, occlusion, prep design among the few. It is very important to follow all the steps in precise order as far as esthetic smile design cases are concerned. It is prudent for a practitioner to analyze all aspects of the arches before starting with complex rehabilitation cases.
