Deciding whether indirect or direct restorations will be the most effective in posterior teeth can be challenging, but GC has the answer.
Direct restorations or indirect restorations? Deciding which is the most clinically effective in posterior teeth is a question clinicians face on a regular basis.
Posterior teeth can be restored either way depending on the clinical situation and the amount of remaining tooth substance. Every clinical case has its own requirements that need to be fulfilled by material selection and the particular technique chosen. The aim is to create a restoration that best restores the form, function and aesthetics of the tooth.
The choice between direct and indirect composite restorations can be a challenge. However, for the majority of Class I, III, IV and V restorations, as well as most Class II (MO, DO and MOD) restorations, direct restorations are clearly indicated (Smithson et al, 2011).
Single visit direct posterior restorations allow for preservation of tooth structure. In this technique, following etching and application of bonding agent to the cavity, the composite restoration is built up in layers. This allows sculpting of the final restoration.
Advantages include strength of remaining tooth structure, potential for repair and closely matching the aesthetics of the lost tooth structure.
The complete workflow for direct restorations in posterior teeth
Clinicians have a wide variety of options when selecting direct restorative materials for posterior restorations. But what matters is the strength and durability of the material, while also delivering excellent aesthetic results. GC has the solution.
Step One – Bond with G-Premio BOND
G-Premio BOND is a universal bonding agent with excellent bond strength and is compatible with all etching modes. It can be used for direct bonding as well as repair and hypersensitivity treatment.
Step Two – Reinforce with everX Flow
everX Flow is a short-fibre reinforced flowable composite indicated for dentine replacement in direct restorations (together with a conventional composite as enamel layer), and for core build-up.
everX Flow’s high thixotropic viscosity allows it to flow and adapt perfectly to the cavity floor without slumping – even in upper molars. Its exceptionally high fracture toughness reduces the risk of catastrophic failures making it ideal for use in weakened or cracked teeth, especially after amalgam removal.
Step Three – Cover
GC offers two exceptional options to cover and finish the restoration:
- G-ænial A’CHORD universal composite with a simplified unishade system which achieves the aesthetics of the 16 classic Vita shades using just 5 core shades. The secret behind G-ænial A’CHORD is GC’s Full-Coverage Silane Coating (FSC) and High Performance Pulverized CERASMART (HPC) – giving the material its high strength, low wear, gloss retention, low discoloration and excellent radiopacity
- G-ænial Universal Injectable universal composite with a high load of ultra-fine barium particles and GC’s FSC technology brings exceptional strength and wear-resistance for long-lasting aesthetic restorations. As GC’s strongest composite – even stronger than leading paste composites on the market – it’s indicated for all cavity classes without a covering layer.
When used together these products provide a complete, simplified three-step workflow for direct posterior restorations.
