This document discusses procedures for repairing different types of fractures in complete dentures. It describes common types of denture fractures like midline fractures and fractures involving individual teeth. The most common fracture is in the midline of the maxillary denture due to pressure from ridge resorption. The repair process involves reassembling pieces, making a plaster index, beveling edges, and adding acrylic resin to fuse the pieces back together. Tooth replacements and repairs to flanges or posterior palatal seals follow similar steps of indexing the area and adding acrylic. Finishing involves trimming, polishing, and ensuring proper fit.
The patient who requires a single denture opposing a natural or restored dentition challenges the clinician even more than the completely edentulous patient does. This is due to the biomechanical differences in the supporting tissues of the opposing arches. So a proper evaluation, correction of the existing factors and proper sequence of denture construction is necessary to give a more stable prosthesis.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

2 Case Reports of Gastric Ultrasound
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

3. Learning outcomes
1. List the types of denture
fractures.
2. Explain the procedure for denture
repair.
3. Explain the procedure for denture
tooth replacement.
4. Types of Denture Fracture
Midline fractures
Fracture or chipping of a
portion of the denture
Multiple fractures (more
than two pieces)
Cracks in the denture
Fracture or dislodgement
of one or more teeth
5. The most common
fracture of a
complete denture
occurs in the
midline of the
maxillary complete
denture.
Causes of denture fracture
6. This occurs because
as a ridges resorb,
the palate does not
resorb. This results in
the dentures
contacting only in the
palatal area and not
contacting the ridge
area.
7. Therefore all the
pressure is
transferred to the
middle of the palate.
The stresses
increase as the
ridges resorb,
increasing the
likelihood that the
denture will fracture
in the mid-palate as it
8. Other causes of denture
fracture
1. Deep labial frenal notch
2. Absence of labial flange
3. Incomplete polymerization of acrylic
resin
4. Previous repair
5. Maxillary posterior teeth placed
buccally
6. V shaped palatal arch
9.
10.
11.
12. 7. Accidental dropping of
the denture
8. Faulty denture design
resulting in areas of
inadequate thickness
9. High occlusal loads
10. Single denture
15. When the dentures can not be repaired
When the broken pieces cannot be
joined accurately
When the dentures need to be replaced
anyway due to poor fit or occlusal wear
or any other reason
16. Types Of materials used in
repairs
1.Chemical-Cured acrylic
2.Visible Light Cured (VLC) acrylic
19. • Broken parts are
assembled &
fixed together
with sticky wax
on the polished
surface.
• Assembled
parts may be
strengthened
with burs or
plastic sticks.
20. • Any undercut on
the fitting surface is
blocked out with wax
or clay.
• The fitting surface
is painted with
petroleum jelly.
21. • Stone plaster is poured into
the fitting surface. After stone
has set, the denture is
removed from the cast and
cleaned from any traces of
sticky wax.
• Fractured edges are
widened along the fracture line
and beveled towards the
polished surface to increase
bonding surface area.
22. • The cast is painted with
separating medium and
the denture is secured to
the cast with rubber
bands.
• Self cure acrylic resin is
applied to the modified
fracture area until the
area is overfilled.
•Cure the denture in the
pressure pot.
38. Here a fractured flange is shown, but the process is
the same for any fracture of a denture base. A midline
fracture of a maxillary or mandibular denture would
follow the same steps.
Fracture Line
39. First, hold the pieces of the fractured appliance
together to evaluate their “fit”. If the segments
don’t relate very accurately, we have a problem
at this stage.
40. While CAREFULLY holding the segments
together, have someone flow sticky wax at
the fracture line to temporarily hold the
segments together.
41. These images show the segments held together with
sticky wax. Note that the inner aspect of the denture
has no wax in it at all. The fracture is visible as a fine
line on the inner surface of the denture. We will now
make an index which will orient the segments during
the remainder of the repair process.
42. Once the
segments of the
denture have been
related, we make
an index using fast
setting plaster. The
plaster is first
carefully placed in
the denture in the
area of the fracture
so that we have no
voids in the index
in this area. The
denture is then
inverted on a small
base of plaster to
complete the
index.
43. The denture is inverted on the
base of plaster and the
peripheries smoothed. After
the plaster sets we have an
index to relate the segments
for the repair procedure itself.
44. The denture is then lifted off the
index and the edges of the broken
segments are beveled toward the
outer surface. This will provide
fresh acrylic to allow a better repair
as well as provide more surface
area for the repair acrylic to bond
to.
45. Here we have two views of the beveled surfaces
ready for the addition of repair acrylic. Note the
bevel is toward the outer surface of the denture.
This leaves the inner surface minimally disturbed.
We also have a large surface area for the new
repair acrylic to form a bond with.
46. Repair acrylic is then placed
along the fracture line by
dipping the brush in liquid
and picking up a small
increment of powder. The
increments of repair acrylic
are placed in the defect and
the denture placed in warm
water.
47. The completed repair is removed from
the index and the area smoothed with an
acrylic bur.
48. After the repaired area has been shaped and
smoothed with a bur, the denture is polished
with pumice.
51. After block out of the undercuts in the denture
a cast is poured into the denture itself. Care is
taken to create a land area around the
denture especially in the posterior area.
52. The denture is removed from the cast. The posterior
area corresponding to the palatal seal is a good
reproduction of the inner surface of the denture with
the impression wax. Remember, the green stick had
been molded in the patient’s mouth and the
retention was seen to have been increased.
In the lab exercise, you will do a repair of a fracture of the mandibular complete denture. This is mainly because It is easier to break the mandibular complete denture into two pieces than it is to break the maxillary complete denture into two pieces.
