GC presents a masterclass on step-by-step protocols for bonding direct and indirect restorations, available upon request as a webinar.
Nik Sethi is the president-elect of the British Academy of Cosmetic Dentistry and director of Elevate Dentistry, Square Mile Dental Center and Dental Beauty Basildon.
In a recently released Dentistry webinar, Nick spoke in depth about his step-by-step, evidence-based protocols for achieving successful bonding in both direct and indirect restorations using only proven techniques and materials.
As a specialist in restorative dentistry, Nik believes that there is a lot of confusion among dentists when it comes to bonding and the choice of bonding agents. His webinar aims to provide a clear workflow for all adhesive-bonded restorations to overcome everyday problems such as marginal staining, post-operative sensitivity, premature bond failures, fractures, fissures and secondary caries.
Read on for a preview of this insightful webinar.
The process
First, adhesive success begins at the design stage. Nick talks through a detailed assessment of a case to determine whether a direct or indirect remedial approach is appropriate, taking into account both local and general factors.
When teeth will return to compression, Nik considers cavity margin design, shrinkage tendency, the importance of biofilm removal, and why the tooth-restoration boundary is always problematic.
Adhesives
The correct choice of adhesive agent is the key to the success of the restoration. Nik presents the current systems available for indirect bonding, providing advice on choosing the right material for long-term success.
It follows a discussion of the different universal and self-clearing welding systems and presents a self-registration welding protocol using a single-bottle system such as G-Premio BONDor a two-bottle system such as G-2 BOND Universal.
“These are two incredible binders that do the work for you. They are able to set and bond with the dentin without having to carve it first,” he says.
Nik completes the long-term hybrid layer over the dentin by applying a flowable composite. His choice is to use G-ænial Universal Injectable (GUi) as “it’s incredibly full and incredibly powerful.” In his view, it is a healing material in itself!
Base assembly
With the welding protocol complete, Nik proceeds to create a base to form the molars with a predictable build-up protocol, using GUI followed by heated G-ænial A’CHORD universal composite and G-ænial light-cured radiopaque composite restorative.
Finishing and polishing follow, with a reminder that polishing must be done quickly before the composite fully cures.
As part of the base build, Nik demonstrates a mini core build using GUI and explains how to deal with hacks. It gives some useful tips on which photopolymerization unit to use and a brief summary of polishing protocols.
There is also a constant reminder from Nikos throughout his presentation of the importance of having a great relationship with your workshop technician to ensure your restoration is successful every time.
Cementation
The conclusion is the cementation stage, where Nik explains the protocols for try-in, preparation of the adhesion fitting surface for onlay placement after temporary protocols are removed, and lubrication protocols.
To close the webinar, Nik presents a thought-provoking final case study to show that clinicians sometimes need to think ‘outside the box’. One patient presented with three large failed restorations and, due to time constraints, Nik used a direct approach to selective reduction of the cusp to predictably restore the dentin and cusp.
