Short description
This course focuses on how to effectively acquire critical
patient information at the consultation/examination
appointment for success with all types of tissue-supported
complete dentures. It covers effective patient communication,
the clinical examination and managing patient expectations
for predictable and satisfying denture outcomes.
Abstract
This course focuses on essential elements of the consultation/
examination appointment for enhancing the predictability
and success of complete denture fabrication.
It breaks down this initial appointment into three phases:
preexamination consultation, clinical edentulous examination
and postexamination consultation.
- In the preexamination consultation phase, the emphasis
is on actively listening to the patient. Understanding
their previous experiences with dentures, their
adaptability to prostheses, and their specific desires
and expectations for new dentures is essential.
- The clinical examination involves an assessment of
the patient’s oral conditions. This helps determine
their restorative needs in alignment with their desires
and expectations. The dentist evaluates oral health,
anatomy and factors that may affect the success of the
dentures, such as stability of the temporomandibular
joints and potential airway obstructions.
- The final phase, the postexamination consultation,
includes a discussion of the findings from the consultation
and examination. Here, various options and recommendations
are presented, tailored to the patient’s
individual needs, wants and expectations.
Additionally, a comprehensive informed consent process
is crucial and should cover all treatment options and their
benefits, risks and associated costs to ensure transparency
and foster patient compliance.
Learning objectives
After completing this course, readers should be able to:
- Conduct a preexamination consultation that establishes
open communication and patient rapport,
leading to a better understanding of patient wants
and expectations..
- Provide a practical clinical edentulous examination,
including evaluating the patient’s oral health and identifying
anatomic factors influencing denture success to
determine the patient’s needs.
- Discuss the importance of patient-centered care,
including: active listening and empathetic communication
to create a comfortable environment where patients can express their wants,
expectations and concerns; and incorporating
information from the findings
of the clinical examination to perform
appropriate treatment.
- Conduct a thorough informed consent
process, including a discussion of treatment
options, risks, benefits and fees, and the
recognition of the patient's right to choose
no treatment.
Introduction
For dentists and their teams, providing a successful
complete denture service requires a combination
of technical expertise, communication
skills and a deep understanding of the patient’s
unique expectations and needs. The first step
in this process is the consultation/examination
appointment. This course examines key aspects
of this initial appointment that can enhance the
effectiveness and predictability of the complete
denture experience.
All denture fabrication steps must be done
competently by the dentist, dental assistant and
dental laboratory technician to create well-made
complete dentures that are stable; have
adequate occlusal vertical dimension, retention
and aesthetics relative to the patient’s anatomy;
and have all posterior denture teeth contacting
evenly in centric relation occlusion. However,
the dentist should understand that even competently
crafted dentures may face rejection by
the patient. To mitigate this unpredictability,
dentures should be skillfully made according to
the patient’s wants and expectations.
Fundamental aspects of the consultation
examination appointment
- Preexamination consultation: Patient
interview before the visual clinical examination.
Establish a foundation for open
communication and understanding patient
expectations.
- Visual clinical examination of the
edentulous stomatognathic system:
Comprehensive evaluation of patient oral
health and anatomical factors influencing
denture success.
- Postexamination consultation: Patient
consultation after the visual clinical examination.
Discuss findings, thoughts, options
and recommendations based on patient
expectations and oral examination results.
Competently completing the denture fabrication
steps leads to fewer problems after
the delivery of the final dentures and greater
predictability and success. Life is too short to
routinely fabricate dentures that are unpredictable
and unsuccessful!
This course is the first of a five-part series
about keys to success with tissue-supported
complete dentures, which explores fundamental
denture fabrication techniques surpassing
those commonly employed by many dentists.
Following these fundamentals should result in
higher predictability and success for the dental
team with analog, digital and implant-retained
tissue-supported complete dentures. This course
aims to inspire and encourage dentists and
dental teams to incorporate the fundamentals
covered and persist in their learning journey,
fostering growth and continual improvement of
their denture services.
Preexamination consultation
Understanding patient expectations
The consultation/examination appointment
is not solely about assessing the patient’s oral
health; it’s also an opportunity to connect with
and learn more about the patient. Engaging in
open and empathetic communication helps to
create a comfortable and safe environment for
patients to express their wants, expectations and
concerns. The dentist should ask patients about
their experiences with former dentures and denture
services. Understanding their history and
experiences with dentures will help the dentist
gauge the potential for successful treatment and
assist in deciding if referral of the patient is the
best option.
It’s important for the dentist to understand the
patient’s expectations concerning their desired upcoming dentures. Consider a scenario where
an edentulous patient anticipates eating a hamburger
wearing tissue-supported prostheses as
effortlessly as they did in their teenage years with
healthy natural teeth. Such elevated expectations
may lead to dissatisfaction with new dentures.
The dentist and patient must recognize that
dentures are prostheses with differences from
natural teeth and gums, and the patient must
adapt to changes in speech, function and feel.
Active listening
The preexamination interview with the patient
should occur before the visual clinical examination.
A good opening for the dentist with a new
patient is asking, “How can I help you?” and then
listening attentively. Ask the patient to assess
and describe the conditions with their existing
dentures (e.g., aesthetics, comfort, retention,
function) and discuss their likes and dislikes
with present and past dentures. Also, inquire
about the patient’s wants and expectations with
new dentures. Listen with the intent to understand
the patient.
The preexamination consultation is a time
to understand the patient, rather than educate
them about dentures. Education should occur
after the clinical examination to inform the
patient about restoring their conditions and
needs in relation to their wants and expectations.
At the preexamination consultation, the
dentist should take the time to actively listen to
the patient’s concerns and expectations. Many
patients seeking new complete dentures may
have had negative experiences or fears associated
with dental procedures. By empathetically
listening, the dentist can gather valuable information
and establish trust, a crucial factor in the
success of any dental treatment.
The comprehensive clinical oral examination
The clinical examination begins only after
completion of the preexamination consultation,
where the patient has discussed their wants
and expectations and the dentist has listened and spoken briefly in general terms. After
understanding the patient’s wants and expectations
and the conditions and restorative needs
learned at the oral examination, the dentist
will discuss their findings, impressions, options
and recommendations at the postexamination
consultation.
A thorough oral examination of the edentulous
patient is a cornerstone of successful complete
denture treatment. Beyond assessing the
patient’s oral health, it provides insights into the
anatomical and physiological factors that may
affect the success of dentures.
For predictability and success with complete
dentures, it’s essential to treat patients who have
stable (not changing) stomatognathic systems;
this includes stable (noninflamed) denture-supporting
tissues and temporomandibular
joints (TMJs). If final impressions are made of
unstable inflamed, swollen tissues (Fig. 1a), the
denture will not fit well to the healed, unswollen
tissues (Fig. 1b). Other conditions that can lead to
unpredictability include the absence of retromolar
pads, hypertrophied maxillary tuberosities, large tori or exostoses (Fig. 2), salivary hypofunction
and mobile (displaceable) alveolar ridge
soft tissues (Fig. 3). Also, any pathologic areas
detected during the oral cancer screening, which
should be part of the oral examination, should be
addressed before beginning denture fabrication.

Fig. 1b
Fig. 2
Fig. 3
Evaluate the TMJs and masticatory muscles,
looking for red flags indicative of problems
and instability. Evaluation can include using
palpation and a stethoscope to notice if clicking,
popping or crepitus of the joints is present.
Discuss current or past pain of the patient’s TMJs
and ears, including their history of headaches
and neck aches. The TMJs can be assessed with
manual bilateral mandibular guidance and load
testing of the right and left TMJs to verify centric
relation or detect possible temporomandibular
disorders and instability (Fig. 4).
Fig. 4
Stable TMJs are crucial for attempting successful
and predictable edentulous restorations.
A thorough understanding of TMJ anatomy,
function, and disorders and diagnosis of temporomandibular
disorder (TMD) is beneficial
with this step.
Another important element of the clinical oral
examination is screening the patient for obstructive
sleep apnea. The dentist can use the STOPBANG
questionnaire and a home pulse oximeter
for screening. The vertical dimension of occlusion
of the edentulous restoration may affect the
patient’s airway and should be assessed. If the
edentulous patient uses a CPAP (continuous positive
airway pressure) machine, implants may be
needed for denture support or retention for a seal
of the CPAP face mask. Be sure to consult with
the patient’s physician regarding these matters.
Suppose the patient has an unstable condition
such as TMD, obstructive sleep apnea or irritated,
inflamed, ulcerated denture-supporting
tissues. In that case, it is important for the dentist
to decide how the condition will be resolved
before proceeding with the fabrication of new
final denture prostheses.
Aside from the patient’s physical conditions,
remember that their attitudes and adaptability
toward their new dentures are critical regarding
predictability and success with tissue-supported
complete dentures.
Assessment of oral health and anatomy
During the oral examination, evaluate the overall
health of the oral tissues, including the condition
of the oral mucosa. Identify and address any
current oral health issues that may affect the
success of the complete denture treatment. Also,
evaluate existing prosthetic appliances and their
effects on the stomatognathic system.
Some positive characteristics of an edentulous
maxilla regarding the fabrication of tissue-supported
complete dentures include:
- Abundant keratinized attached tissue. Thick
denture-supporting tissues make wearing
dentures more comfortable for the patient.
- Palate U-shaped in cross-section.
- Absence of undercuts and tori.
- Adequate residual alveolar ridge bone for
denture retention, stability and support.
- Frenum and muscle attachments below the
crest of the ridge.
- Well-formed tuberosities.
- Well-defined hamular notches, which
indicate the location of the posterior
extension of the denture and help with
denture retention.
Some positive characteristics of an edentulous
mandible regarding the fabrication of tissue-supported
complete dentures include:
- Well-defined retromolar pads.
- A well-formed buccal shelf to support the
mandibular denture.
- Frenum and muscle attachments below (apical
to) the crest of the alveolar ridge.
- Absence of undercuts and tori.
- Abundant attached keratinized mucosa.
- Adequate residual alveolar ridge vertical
height and buccolingual thickness, similar
to the cast in Fig. 5.

Assessment of facial characteristics
Appraise the patient’s facial characteristics,
including lip support and length, the vertical
dimension of occlusion and the aesthetics of
their smile. Look for red flags indicative of
challenges that may present during the denture
fabrication. This assessment can help achieve
patient satisfaction with their new dentures or
may lead the dentist to refer the case because of
complex conditions.
Radiographic evaluation
Incorporate a radiographic evaluation to assess
bone density and the overall oral anatomy.
Radiographs provide valuable information about
the underlying structures and aid in treatment
planning and detection of pathology. The dentist
or radiologist should carefully evaluate and
diagnose any radiographs taken. If the patient is
considering placement of dental implants in the
future, consider recommending 3D cone beam
computed tomography.
POSTEXAMINATION CONSULTATION
Considering the clinical findings and patient
expectations, the dentist should decide if they
can achieve acceptable results and would like
to treat the case or if they want to refer it. It is
important to emphasize that referring patients
to colleagues is acceptable and encouraged when
appropriate.
Considering the patient’s wants, expectations
and restorative needs, inform them about the
available treatment options, what to anticipate
with each course of action, the associated fees
and the recommended treatment. Advise the
patient about conditions with potential for
improvement (e.g., retention, aesthetics). Be positive
and realistic.
Discuss options regarding dental implants
with the patient, such as:
- Placing dental implants after the dentures
have been fabricated. However, inform the
patient that bone reduction may be needed
if implants and attachments are placed.
Ensure they are aware of the additional
costs for these added services.
- The denture base will weaken in the areas
of implants and attachments, and denture
fracture may require repair or refabrication
of the denture.
- The patient may need to have the current
new dentures remade or rebased after bone
reduction when implants and attachments
are added.
The dentist should understand and accept
the limitations of dental implants and digital
technology related to complete denture success.
While it is exciting that implants can
often improve a denture, they usually will not
transform a poorly made denture into a suitable
denture. Digital denture technology can only
produce adequate dentures if accurate information
is input (e.g., accurate impressions, records
of tooth position and vertical dimension of occlusion,
etc.). In other words, garbage in, garbage
out. Also, the digital denture technology must
be sufficiently advanced to produce adequate
dentures. The dentist should strive to choose an
excellent digital denture manufacturing system
and input quality data.
Patient education
Engage in a discussion with the patient about
what to expect with new tissue-supported dentures.
Clarify that chewing function will notably
decrease compared with healthy natural teeth.
Additionally, emphasize that the new prostheses
will initially feel “different” and potentially
uncomfortable. Inform the patient their speech
will be affected and this is a normal part of
the adjustment process. Address that they will
experience some movement of the dentures in
their mouth. Assure the patient the dental team is
committed to providing support throughout their
adaptation to the new dentures, but accepting
limitations of prostheses is essential. Furthermore,
the dentist should decide the steps they
will take if the patient encounters difficulties and
does not accept the new dentures after delivery.
Empower patients by providing education
about the complete denture fabrication
process and obtaining informed consent.
A well-informed patient is more likely to accept
and be satisfied with the treatment outcome.
The informed consent process
Ensure a thorough informed consent process,
explaining potential risks, benefits and alternatives
to tissue-supported complete denture treatment.
Address any questions or concerns the
patient may have, and document the informed
consent process in the patient’s clinical records.
Have the patient and a witness sign and date a
written informed consent form.
In the form, include the following issues if they
were discussed:
- The option of no treatment and its consequences.
(Note that this option was presented
but is not recommended.)
- The option of small-diameter (less than
3 mm) implants or root-form (3 mm or more)
implants in the maxilla and mandible to
retain dentures.
- The option of All-on-4-6 fixed (dentist-removable)
restorations.
- The option of implants with fixed bridges.
- Benefits/advantages, risks/disadvantages
and fees of all options.
- The fact a denture can fracture and need
repairs or replacement at additional fees.
- The fact denture teeth can wear, necessitating
replacement of teeth or remaking of the
denture at additional fees.
- The fact a patient should not attempt to
repair their own denture but instead should
return to the dentist for evaluation and
discussion of repair options.
- The fact the American Dental Association
reports that, over time, dentures may need
relining, rebasing, or replacing. The typical
life of dentures is between five and 10 years.
Setting realistic expectations
At the postexamination consultation, inform
the patient about the complete denture process,
including the time required, potential challenges
and the expected outcome. Discuss the possibility
of additional appointments with laboratory
time if more steps become necessary for the
denture fabrication process. Be transparent
about what complete dentures can and cannot
achieve. Realistic expectations contribute to
patient satisfaction and compliance throughout
the treatment.
Visual aids such as models, diagrams and
videos are useful when explaining the various
stages of complete denture treatment. They
can enhance patient understanding as well as
facilitate better communication. If appropriate,
provide printed or digital information about the
treatment plan and supply denture and oral care
instructions. These materials serve as valuable
references for patients and reinforce the information
discussed during the consultation.
Incorporating patient-centered care
Adopting a patient-centered approach is critical
to the success of complete denture treatments.
Strategies should be tailored to meet
each patient’s individual needs and preferences.
Develop individualized treatment plans based on
the patient’s oral health, lifestyle and preferences.
Consider factors such as the patient’s ability to
adapt to new prosthetic appliances and their
expectations regarding aesthetics and function.
Encourage open communication and seek
patient feedback throughout the consultation/
examination and treatment process. Actively
address concerns or discomfort the patient
reports, fostering a collaborative and supportive
dentist-patient relationship.
Conclusion
The consultation/examination appointment
for complete dentures is a multifaceted process
beyond traditional dental examinations. Success
in this phase requires effective communication,
examination skills and a patient-centered
approach. By understanding the patient’s expectations,
conducting a visual clinical examination,
providing patient education and adopting
a patient-centered care model, dentists can lay
the groundwork for a successful and satisfying
complete denture fabrication experience.
Taking the time to learn and master these
fundamentals for success in the consultation/
examination appointment and for all phases of
the fabrication process promotes optimal treatment
outcomes and fosters positive long-term
patient relationships.
