Introduction • Zirconia crowns have gained popularity over the past decade.

what Can Cause Ill-Fitting Zirconia Crowns? • Dental crown and Hybrid Denture was rushed :When crowns and hybrid denture are rushed, errors occur, like incorrect margins. Crowns cemented with an open margin allows entry or seepage of saliva inside the crowns, which causes decay in your patient’s gums. • Crown wasn't cemented properly: Clinicians must meticulously check the crown margins to avoid potential errors during cementation, sort of a niche within the patient’s crown. • Impression was questionable: Air pockets, drags or pull marks, missing impression data, inaccurate marginal impressions and poor impression material will all affect the quality of the impression.
How to Fix Debonding Complications • Zirconia crowns are debonding, try altering your cementation process. • Most technicians will test out the fit of the zirconia crown within the patient’s mouth before cleaning the tooth with pumice. • Even though these are standard procedures, clinicians sometimes fail to decontaminate the intaglio thoroughly, which causes the bonding process to fail. • Because zirconia bonds with phosphate groups, it’s critical to properly remove the phosphate groups therefore the oxide sites can bond successfully in your patient’s mouth.
Three Ways to urge obviate Phosphate Groups • Sandblasting: Although sandblasting the inside surface with 50-micron diameter alumina is typically not recommended, most manufacturers do recommend sandblasting the inside surface very lightly at a coffee pressure. • Sodium hypochlorite : The intaglio of the crown is wiped with gauze soaked during a 5% concentration of hypochlorite or full peroxide , which is removed by rinsing with water and air-drying the restoration. • Ivo clean: Use a proprietary solution like Ivo clean. Leave the solutions on the crown for 20 seconds before rinsing. The crown is air-dried and ready to bond.
Cementing and Finishing Zirconia Restorations • Quite often marginal finishing is required when fitting and cementing Zirconia restorations. • Excess cement must be removed to avoid plaque formation which may cause tooth sensitivity and periodontitis . • Gingival margins are often finished using non-cutting, safe-end finishing burs which will protect the soft tissues. • Although these adjustments may slightly roughen the surface of a Zirconia restoration, it should be easy to shine , creating an exceptionally smooth surface
Ensuring Restorations Don’t Rock Facial-Lingualy • When the digital image of the patient’s tooth is formed , any irregularities are removed as milled restorations have smooth surfaces internally and may not fit over irregularities or undercuts. • When fabricating zirconia restorations, have your clinician confirm that the pc program is close to make well-fitting margins, while specifying the size of the space between the fit surface and thus the prep site. • Ill-fitting crowns can cause unhappy patients.
