ABSTRACT

Introduction: This article describes an efficient chairside method for immediate fabrication of an esthetically superior pontic, compared to an acrylic denture tooth, prior to extraction of a tooth due to any underlying reason.

Discussion: Taking an impression of the patient’s own individual tooth permits the orthodontist to create a pontic with precise anatomy, size, and esthetics. The total time for the procedure of pontic assembly is less than a few minutes.

Conclusion: This small chairside procedure of pontic fabrication can go a long way in delivering esthetics as well in building up the confidence of the patient and that too in a very short time period.

Clinical significance: Simple, easy, cost effective, and time-saving chairside procedure.

Keywords: Chairside, Orthodontic, Resin, Riding pontic.

INTRODUCTION

Riding pontics are acrylic teeth that act as temporary prosthesis during fixed orthodontic treatment in a patient with missing tooth, especially in the smile zone.1 This article describes an efficient chairside method for immediate fabrication of an esthetically superior pontic, compared to an acrylic denture tooth, prior to the extraction of a tooth due to any underlying reason (Fig. 1).

PROCEDURE

DISCUSSION

Taking an impression of the patient’s own individual tooth permits the orthodontist to create a pontic with precise anatomy, size, and esthetics.3 The total time for the procedure of pontic assembly is less than a few minutes. An impression of the teeth made inside the mouth is far superior to taking an impression of the tooth after extraction for several reasons:

If the patient presents with a lost or extracted tooth, the clinician can use an adjacent or contralateral tooth to make the impression mold. If a central incisor is missing, the adjacent central incisor should be used for exact size and shape, with minor interproximal re-contouring as needed, to improve the shape of the tooth. A single-tooth pontic will tend to rotate on a round archwire. To prevent this, the pontic is bonded labially to the adjacent tooth on the one side.4 This can be altered according to the case as the leveling and alignment progresses.

CONCLUSION

The strive for esthetics to be delivered at every step is an endless job in the field of orthodontics. This small chairside procedure can go a long way in delivering esthetics as well in building up the confidence of the patient.
