Chairside, Surgical Support and Instruments

Study guide

The nurse’s own topic — what you prepare, hand over, hold, handle and do when something happens. It is also the most component-heavy part of the certificate, and the components are tested by description rather than by name, so a vocabulary list learned in the wrong direction will not answer the questions.

Preparing the environment and supporting the patient

The work before the operator sits down, some of which the GDC describes explicitly.

• The GDC describes tasks dental nurses generally carry out, and a question may ask whether a described task is among them.
• Surgical suction and irrigation have stated purposes during placement, and the purposes are not the ones assumed from ordinary chairside suction.
• The implant text gives a reason for completing the procedure promptly once the flap is raised, and that reason is examinable.

Instruments, drills and decontamination

A block where the sequence and the handling rules are both specific.

• Drills are handed over in sequence, and the drill that finishes the preparation carries its own stated significance.
• Instruments laid out and never used are still treated as used for decontamination purposes — a rule that catches people out.
• Aspirating equipment has its own required protections in the guidance.

Components and materials

Two extended matching sets, and the densest vocabulary in the certificate.

• Fixture, abutment, cover screw, healing abutment, impression coping, analogue and the rest are all matched from descriptions of what they do.
• Chairside materials are matched the same way — membranes, graft materials, sutures, cements — so learn each by its function.
• Grafts and membranes carry their own content: what a barrier is there to do, what resorbable materials require, and what the alternatives to the patient’s own tissue are.

Impressions, torque and the restorative visit

The second half of the treatment, where the numbers live.

• Open and closed impression techniques differ, and divergent implant angulations decide which is used.
• A digital scan requires something fitted first, which is a straightforward mark if you know it.
• Torque values are stated for the abutment screw and handled differently for driving the fixture itself; the amount of cement needed for a cemented crown is also stated, and excess cement is a peri-implantitis risk rather than an aesthetic one.

When something happens

Medical emergencies and the immediate response, including a full extended matching set.

• The emergency drug store is governed by current resuscitation guidance rather than by what an implant practice thinks it needs.
• A collapse part-way through a placement raises a specific question about the state of the site, and the GDC places the nurse somewhere specific in what follows.
• The extended matching set asks for the nurse’s single immediate response to an event — first action, not eventual management, and the distractors are all things that happen later.

In the exam Build the component and material lists as description-to-name pairs from the start; every one of the three big matching sets runs that way. For the emergency set, answer with the immediate response — the most common error is selecting a correct action that belongs three steps further on.
