Composite restorations: closing and open gingival embrasure


Tariq Bashir presents a case through which he handled a fellow dentist with aesthetic restorations to shut a black triangle upfront of her summer time wedding ceremony.

A 27-year-old dental colleague dentist attended the clinic.

She was eager to have composite bonding carried out to enhance the aesthetic look of her UL1 and UL2 earlier than her summer time wedding ceremony (Determine 1).  

She had undergone orthodontic remedy prior to now and was exhibiting some indicators of relapse.

A small rotation of the UL1 was famous and, because of the triangular tooth form and lack of papilla, a black triangle was seen between the UL1 and UL2 (Determine 2).  

Unpleasant black triangles, or open gingival embrasures, may be efficiently handled with a spread of aesthetic choices. Because the affected person was a dentist, she understood the advantages and process concerned with composite bonding.  

Previous to the remedy, she accomplished a course of residence tooth whitening utilizing Boutique by Evening 10% carbamide peroxide with night-time trays. 

Whitening was adopted by a two-week ready interval to permit shade stabilisation and get rid of any residual bleaching agent that would cut back the enamel-to-resin bond energy.

Shade choice 

On the remedy appointment the shade was chosen utilizing composite buttons with Kulzer Venus Pearl nano-hybrid composite B1 and BL shades.  Small quantities of the closest matching shades have been chosen and positioned on the UL1 and light-cured.  

Subsequent, retracted pictures have been taken in color and monochrome to examine the composite worth, to make sure an in depth match can be achieved for the enamel shade.  

The B1 composite button on the mesial facet of UL1 was revealed to be the closest matching shade (Figures 3 and 4).  

No additional shades can be required for this case as solely a small quantity of composite was wanted for the mesio-incisal facet of the tooth.  


Retracted pictures with a black contraster have been additionally taken to examine the incisal translucency (Determine 5). Rubber dam was then positioned with molar clamps on the higher first molars and the higher anterior tooth have been remoted.  

Floss ties across the anterior tooth have been used to stabilise the dam (Determine 6).  

Rubber dam not solely helps with isolation to minimise contamination of the bonding web site, it additionally aids retraction of the papilla to create a beneficial subgingival composite emergence. 

A minimal 1-2mm bevel preparation was carried out on the mesial facet of the UL1. Then, the UL1 and UL2 have been particle abraded with Aquacare aluminium oxide 29 micron powder to take away biofilm and improve the composite bond energy.  

The margins have been etched with 37% phosphoric acid etch gel.  

A two-bottle, total-etch bond was then utilized to the surfaces and air dried, earlier than light-curing for 20 seconds in accordance with the producer’s directions.  

Seamless contouring

The mesial facet of the UL2 was first outlined utilizing a posterior matrix tailored across the palatal facet. The B1 Venus Pearl shade was utilized to create the brand new mesial contour of the tooth.  

I’ve used Venus Pearl for greater than 10 years for anterior and posterior composite instances.  

Robust and sturdy, the fabric delivers superior polishability. It blends seamlessly with the pure tooth resulting from its chameleon-like traits and simple dealing with.  

The mesial elements have been then constructed out and formed with Venus Pearl B1 composite utilizing Garrison Varistrip Mylar matrix strips.  

The Mylar Pull method was utilized to finalise the form of the lateral incisor.  

The composite was brushed into place utilizing a quantity two brush with wetting resin, and light-cured.  

The identical course of was repeated to enhance the distal type of the UL1. Additionally, to even the area between the UL1 and UL2.  

Ending and sharpening

The composite restorations have been completed utilizing Sof-lex discs of lowering coarseness.

The Kulzer Venus Supra sharpening package was used with water to provide a ultimate pure sheen.  

The package has simply two grades of sharpening factors so it’s time-saving and easy to make use of.  

The end was achieved with a fantastic goat hair wheel and aluminium oxide paste.  

The occlusion was checked in all actions throughout the chewing sample and no interferences have been discovered. 

The affected person was ecstatic with the end result. She couldn’t wait to point out the consequence to her fiancé, who can be a dentist.  

Submit-treatment pictures have been taken (Determine 7). Closing pictures might be obtained on the assessment appointment throughout the affected person’s subsequent go to.  

I used to be honoured to assist enhance this colleague’s smile in time for her massive day this summer time.

 Her fiancé has since booked an appointment with me. Additionally they had restorations positioned, which I created with Venus Pearl!
