BioClear for Black Triangles
BioClear for Black Triangles
Repair and smooth your smile with Bioclear Black Triangle treatment. This minimally-invasive technique corrects the appearance of spaces between the teeth near the gums resulting in a blended smile without empty gaps or spaces.
Bioclear treats and fills gaps using a combination of resin filling and a matrix band to build up the gum tissue and reduce spaces. This can be done in a single appointment, so prepare to walk out of our office with renewed confidence.
The Benefits Of Bioclear For Black Triangles
Bioclear for black triangles repairs and improves the appearance of small or triangular-shaped gaps between the teeth. Other benefits of Bioclear include:
- Improved appearance of the smile
- Minimally invasive procedure
- Single appointment procedure
- No removal of healthy tooth structure
- Improved oral health
- Prevents future dental issues
It’s stronger and longer lasting
The typical longevity of a composite restoration—like certain cavity fillings—might be two to five years. Traditional composites are applied at room temperature, in successive layers. This not only creates noticeable edges at the gumline, but also weakens the structural integrity of the restoration. After that, they need to be touched up or replaced. There was clearly room for improvement.
Bioclear uses a heated composite made by 3M that is flowed in, rather than layered. Essentially, the material that will form the new tooth structure is combined with a warmed, viscous material that allows it to be flowed into the Bioclear Matrix, creating a single, monolithic fill that is cured (hardened) with light. The result is harder and more structurally sound than layered composite alone. Bioclear restorations typically last fifteen to twenty years or more.
Our Method for Posterior Fillings
Class II Pre-Operative View
Rubber dam isolation is always preferred. Groom contacts with Bioclear TruContact Sander before rubber dam placement to expedite the process and avoid tearing the rubber dam.
Disclose the Tooth to Identify Biofilm
Place Bioclear Dual Color Disclosing Solution with a disposable brush onto the dried tooth.
Pre-Wedge with Diamond Wedge
The wedge can be placed from buccal or lingual directions. If possible, the wider end near the handle should be placed into the widest, deepest part of the embrasure.
Cavity Preparation and Beveling
The pre-wedge helps to protect the dam, soft tissue, and neighboring tooth. Bevel using Komet USA’s fine trimming diamond FSD3F.FG.031 or fine grit finishing diamond 8833.FG.008.
Finished Cavity Preparation
For most cavities, no mechanical retention via box shape prep is needed when the proper Bioclear Class II preparation is cut.
Run Sanding Strip Through Contact
The contact area must be lightly broken. It is much safer to use a Komet lightening strip instead of a bur in order to protect the neighboring tooth.
Blast Tooth Inside and Out
The blaster has 3 purposes, first to remove biofilm from the infinity edge area, second to remove the pellicle from enamel past the bevel, and third to cleanse the inside of the cavity.
Use EMHI to Determine Matrix Selection and Cure Depth
The numbers on the Evolve Matrix Height Indicator (EMHI) correspond with the numbers on the Evolve matrices to help determine matrix height selection. The colors on the EMHI indicate if the composite should be cured in one layer or two.
Place Evolve Matrix and Wedge
The Evolve Matrices are rugged and will withstand heavy seating pressure. Hold the “Tab” against the neighboring tooth during wedge insertion to keep matrix fully seated and stable. To aid separation, use the largest wedge that will fit in the embrasure. The tab should be centered.
Place TwinRing
The TwinRing has four “hands” that will straddle the wedge. Rock the TwinRing apically, like a rubber dam clamp, to assure full seating.
Place Acid Etch
Make sure to inject acid etch all the way to the infinity edge area (the edge of the matrix). Etch for 15 seconds, rinse and dry.
Place and Massage Adhesive Into Dentin
Apply 3M™ Scotchbond™ Universal Plus Adhesive, with agitation, for 20 seconds. Do not cure.
Air Thin the Adhesive
Gently air dry 3M™ Scotchbond™ Universal Plus Adhesive for a minimum of 5 seconds until there is no adhesive movement. Do not light cure.
Place Spot Welds of Flowable Composite
Place two “Spot Welds” of heated 3M™ Filtek™ Flowable Restorative composite, 1-2mm in diameter, inside, over, and outside the corners of the matrix.
Place Push-Pull, Quick Light Cure
Place the Push-Pull Instrument inside of the cavity prep, with pressure mid coronal-apical, to approximate the matrix for a broad, tight contact. Hold the Push-Pull instrument and the matrix in place while your assistant light cures the “Spot Welds”.
Cure Again After Removing Push-Pull
Light cure the adhesive for 10 seconds after the Push-Pull instrument has been removed.
2nd Application of Adhesive
Wet the cavity area and infinity edge areas with 3M™ Scotchbond™ Universal Plus Adhesive to act as a surfactant. This step allows good flow of composite in the next steps. Do not light cure.
Air Thin the Adhesive
Gently air dry the 3M™ Scotchbond™ Universal Plus Adhesive for 5 seconds.
Inject Warmed Flowable Composite
Slowly inject the warm 3M™ Filtek™ Bulk Fill Flowable Restorative, at a 90 degree angle to the Tooth Restorative Interface (TRI), while displacing the adhesive/surfactant.
Inject Warmed Bulk Fill Paste Composite
Slowly inject the warm 3M™ Filtek™ One Bulk Fill Restorative at a 90 degree angle to the matrix tooth interface while displacing the flowable to ensure strong, seamless composite coverage.
Quickly Shape the Composite
Massage the composite toward the cusp tips and place a general groove. Do not over-manipulate or marginate the composite. Leave the excess.
3-Point Curing: Step 1
Cure the occlusal surface of the 3M™ Filtek™ One Bulk Fill Restorative for 10 seconds.
3-Point Curing: Steps 2 and 3
After removing the TwinRing, cure the bulk fill, through the matrix, on the buccal and lingual surfaces.
Remove Wedge and Matrix
Remove the wedge, then release the matrix from around the tooth with an explorer. Once loosened, spin the matrix out with a hemostat.
Sculpt Restoration with Disc
Round the marginal ridge and marginate the restoration using a 3M™ Sof-Lex™ XT Coarse Disc. Keep disc out of deep interproximal areas in order to maintain the smooth mylar finish.
Grind Simple Anatomy
Use Komet USA’s Q-Finisher carbide H379.FG.0180 to create simple fossa near the contact area and central grooves.
Occlusal Margination
A rubber abrasive point such as a “brownie” is used to marginate the occlusal infinity edge Tooth Restoration Interface (TRI).
Magic Mix Pre-Polish
Apply Bioclear Magic Mix in a disposable prophy cup for further margination and pre-polish.
Rockstar Polish
Polish the tooth with the Bioclear RS Polisher. Use light pressure in the dry phase and then heavy pressure in the wet phase. Have your assistant blow a gentle air stream during the dry phase and constant, full air-water during the wet phase.
