Aesthetic Finishing & Polishing:<br />

Techniques for<br />

Ceramic Restorations<br />

››Abstract:<br />

Contemporary ceramic materials<br />

enable dental professionals to<br />

instill natural aesthetics <strong>and</strong><br />

luster in the restorations of<br />

their patients. The long-term<br />

function <strong>and</strong> performance of<br />

these restorations depend on<br />

numerous factors that include<br />

marginal integrity <strong>and</strong> the<br />

creation of a proper finish <strong>and</strong><br />

polish. Development of an optimal<br />

surface reduces stain <strong>and</strong> plaque<br />

accumulation, minimizes wear,<br />

<strong>and</strong> enhances the appearance of<br />

the definitive restoration. This<br />

presentation exhibits a simplified<br />

protocol for finishing <strong>and</strong> polishing<br />

ceramic restorations.<br />

The increased patient dem<strong>and</strong><br />

for restorations that<br />

closely resemble natural<br />

dentition in aesthetics<br />

<strong>and</strong> function has contributed<br />

to the development of ceramic materials<br />

that provide the needed strength,<br />

durability, <strong>and</strong> beauty to meet those<br />

expectations. Although porcelain restorations<br />

such as CERCON® Zirconia<br />

<strong>and</strong> Finesse® (DENTSPLY Prosthetics,<br />

York, PA) possess intrinsic optical properties<br />

such as opalescence, fluorescence,<br />

<strong>and</strong> translucency that enable clinicians<br />

to achieve beautiful outcomes for their<br />

patients, minor marginal finishing is<br />

needed in virtually every indirect treatment<br />

to remove excess cement or during<br />

finalization of aesthetics or the occlusion<br />

(Figure 1). The use of a systematic finishing<br />

technique following cementation<br />

will improve a restoration’s long-term<br />

performance <strong>and</strong> maintenance of its<br />

marginal integrity.<br />

Once the restoration is seated, excess<br />

cement must be carefully removed, as<br />

any residual cement or marginal roughness<br />

will lead to plaque retention <strong>and</strong> the<br />

associated gingival inflammation. This<br />

will compromise not only the biological<br />

integration of the restoration with the gingival<br />

tissues but also the aesthetics, leading<br />

to chronic marginal inflammation<br />

<strong>and</strong> a potential for recurrent marginal<br />

decay. The restoration, therefore, must<br />

remain as biocompatible as possible (eg,<br />

particularly where in contact with soft<br />

tissues) to provide mechanical strength<br />

<strong>and</strong> aesthetics. Non-cutting, safe-end tips,<br />

which are featured in most tapered burs<br />

in the Midwest® Esthetic Finishing Bur<br />

system (DENTSPLY Professional, York,<br />

PA), enable the clinician to finish gingival<br />

margins while protecting the soft tissues<br />

throughout the procedure (Figure 2).<br />

Prior to selecting or using finishing<br />

instrumentation of any kind, the<br />

clinician should examine his or her<br />

Figure 1. Although ceramic restorations are delivered from the dental<br />

laboratory with a high luster <strong>and</strong> accuracy, minimal reduction may be<br />

necessary following cementation.<br />

Figure 2. Soft tissues can be effectively protected during marginal finishing<br />

with a Midwest ® Esthetic Finishing Bur (DENTSPLY Professional,<br />

York, PA), which features a non-cutting tip on the end of the bur.<br />

Inset: Cement can be removed marginally without lacerating the soft tissue.<br />
