  • Many edentulous patients when examined on routine dental visits, require replacement dentures, although they themselves did not feel this need. This indicates:
    A disparity between the normative need and perceived view of the patients;
    B a possibly large reservoir of unmet need in the edentulous elderly population;
    C an opportunity for a patient to relax during a preliminary conversation;
    D that dental patients may harbour fears over problems encompassing appearance, speech or serious illness;
    E that many conditions may cause extreme discomfort to the denture patient.

  • The examination of the complete denture-wearing patient could be sub-divided into soft tissue and hard tissue assessment. By asking fundamental questions (eg address, family details etc.), that provides an opportunity for the tone of the lips and cheeks assessment, the dentist could indicate:
    A the tips of the maxillary incisor teeth touch the vermilion border of the lower lip during fricative (‘f ’ and ‘v’) sounds;
    B the closest speaking space;
    C the functional relationship of the lips and tongue to the dentures in speech;
    D the appropriate positioning of the upper incisor teeth;
    E the presence of facial asymmetry, atrophy or hypertrophy.

  • The assessment of the edentulous patient could be sub-divided into soft tissue and hard tissue observation. In hard tissue assessment, the edentulous ridges should be basically assessed for:
    A ridge form by the classification of Atwood, which has been modified by Cawood and Howell;
    B ridge consistency;
    C presence of undercuts, knife-edge ridges;
    D modifications to the master casts;
    E form, presence of retained roots, tori and degree of inter-ridge space.

  • If the edentulous patient’s expectations are unrealistic and if the general dental clinician has doubts about the successful outcome of the prosthetic treatment, then the most properly should be, that:
    A no treatment is commenced;
    B the patient is referred to a clinician who specialises in family dentistry;
    C no treatment is commenced and the patient is referred to a clinician who specialises in prosthodontics;
    D the dentures are assessed as functional units;
    E occlusal relations are assessed in retruded contact position.

  • The first part of the denture assessment in the patient’s denture-wearing history is structured as follows:
    A general factors, denture-wearing history, specific factors;
    B assessment of retention, assessment of stability, assessment of dentures as functional units;
    C extension of the complete upper denture, extension of the complete lower denture;
    D upper tooth position, lower tooth position;
    E occlusal relations in retruded contact position.

  • The minimal requirements for any complete dentures should be that they exhibit balanced occlusion in retruded contact position: this means that there should be simultaneous and even bilateral occlusial contacts to prescribe the vertical dimension of occlusion appropriately. Accordingly, appropriate freeway space is measured:
    A by assessment of retention and stability;
    B indirectly by subtracting the occlusal vertical dimension from the resting facial height;
    C by upper and lower tooth assessment of appearance;
    D by occlusal relations in retruded contact position;
    E directly by the biological capacity of the patient to withstand occlusal loading.

  • Some treatment measures for the edentulous patients may require what might be termed ‘rehabilitation devices’. The dentist may find it necessary to modify the patient's existing dentures or to construct a special appliance, as the old denture may be irreversibly altered. Common soft tissue conditions for such a treatment are all the following, except of:
    A denture-related stomatitis, angular cheilitis;
    B unerrupted teeth and retained roots, sharp bony ridges;
    C tissue distortion, fibrous degeneration of the residual ridge(s);
    D border faults, hyperplasia of the border tissues;
    E fibrous degeneration of the residual ridge(s), hyperplasia of the border tissues.

  • To provide ‘rehabilitation devices’ for the edentulous patients, the dentist may modify the patient's existing dentures or to construct a special appliance, looking at the following hard tissue conditions, except of:
    A unerrupted teeth and retained roots;
    B sharp bony ridges, enlarged tuberosities;
    C tori and other bony prominences;
    D border faults, hyperplasia of the border tissues;
    E sharp mylohyoid ridges.

  • A term “rehabilitation devices” (transitional prostheses) for the edentulous patients is used to describe those appliances, which are used:
    A as an adjunct to surgical preprosthetic procedures;
    B for assessment of retention and stability of dentures;
    C for extension of the complete upper denture;
    D as primary devices, to prepare a patient for prosthodontic treatment, or as an adjunct to surgical preprosthetic procedures;
    E for assessment of retention and stability of complete lower denture.

  • Rehabilitation devices (transitional prostheses), the most commonly used for the edentulous patients, include all the following, except of:
    A baseplates to assess tolerance to vertical dimension increase;
    B conditioning appliances to desensitise patients who suffer from headache;
    C a diagnostic appliance for patients having a history of intolerance to a lower denture;
    D stents following surgery to the border tissues;
    E transitional prostheses for patients with exceedingly worn prostheses.

  • Although impressions are imprints produced by ‘the pressure of one thing upon or into the surface of another’, impression making for complete dentures, that implies an active role of the clinician (impressions are made, not taken), does not include:
    A extruding techniques;
    B conventional techniques;
    C template techniques;
    D selective pressure techniques;
    E functional techniques.

  • Definitive impressions for the complete dentures fabrication do not require:
    A conventional techniques;
    B double-base techniques;
    C selective pressure techniques;
    D functional techniques;
    E reline and rebase techniques.

  • According to the clinical guidelines, definitive impressions ‘should record the entire functional denture-bearing area to ensure maximum support, retention and stability for the denture during use’. The primary purpose of definitive impressions, therefore, is:
    A assessment of retention and stability;
    B assessment of upper and lower tooth position;
    C to record accurately the tissues of the denture-bearing areas;
    D occlusal relations in retruded contact position;
    E reline and rebase techniques.

  • It is recommended, that the adaptation of the customised impression trays should be done as for a denture base try-in procedure. The common clinical conditions, requiring selective impression techniques for the adaptation are, except of:
    A displaceable (flabby) anterior maxillary ridge;
    B fibrous (unemployed) posterior mandibular ridge;
    C flat (atrophic) mandibular ridge covered with atrophic mucosa;
    D the presence of facial asymmetry, atrophy or hypertrophy;
    E uncomplete peripheral moulding.

  • The clinical stage following the definitive impressions recording is that clinical visit often referred to as ‘the bite’ or occlusal registration stage. The component parts of this clinical stage do not include:
    A creating and outlining the form of the denture;
    B recording of intermaxillary relations;
    C selection of upper teeth;
    D selection of lower teeth;
    E recording the functional width and depth of the sulci.

  • The vertical relationship as a space between the occlusal surfaces of the teeth of the opposing jaws when they are at rest and with the head upright – the freeway space or interocclusal distance, is determined by a:
    A upper tooth position, lower tooth position;
