Pro-Matrix Case Study

An 87 year old gentleman attended as a new patient and was unconcerned about aesthetics but wanted a functional solution to two teeth which had become fractured and had become symptomatic and were found to be carious. These were LL5 LL6 (lower left second premolar and first molar).

X-rays were recorded, LA delivered and the teeth were isolated with Unodent latex-free rubber dam, Hygienic clamp and Triodent V-ring wedges.The existing amalgam restorations and underlying caries were removed and the cavities were then sandblasted with 50μ aluminium oxide. This was rinsed off, VOCO Vococidacid etchant applied and agitated then rinsed once more.

1

The Pro Matrix was placed on LL6 and the wedges adapted (1). The band was burnished/shaped with an American Eagle teardrop to ensure good tight contacts and the VOCO Futurabond U applied then agitated, air thinned and cured with an Ultradent VALO curing light.

2

VOCO Grandio SO Flow flowable nanohybrid composite was applied to the box up to the band in a very thin layer then cured. VOCO Grandio SO nanohybrid composite was applied to each proximal contact independently and cured on each occasion, converting the cavity into an occlusal (Black's Class 1). The band was then removed and the stages were repeated on LL5. (2)

The tooth morphology was then restored on a cusp by cusp basis with American Eagle titanium nitride instruments and a VOCO Single Tim microapplicator, gently drawn up towards the cusp tips.

3

Basic shaping was then performed with an NSK X600L air turbine using fine diamond burs (yellow band) and polished with VOCO Dimanto points run at slow speed with water spray in an NSK Z25L. (3)

4

The rubber dam was then removed and occlusal checks performed with 40μ Dr Bausch articulating paper and final adjustments made. Contacts were cleared with floss and polished with GC Epitex tapes. (4)
