Long-standing chronic inflammatory tissue appears in single or multiple elongated folds related to the border of an ill-fitting denture.
EpulisFissuratum
located on the palate, rarely outside the confines of the bony ridges.
Papillary hyperplasia
what does papillary hyperplasia look like
The overall lesion appears as a group of closely arranged, pebble-shaped, red, edematous projections.
Denture stomatitis
Oral candidiasis in the form of denture stomatitis is a reoccurring disease common to denture wearers
how does denture stomatitis look/ feel to the pt
Generalized redness, inflamed mucosa of the supporting tissues occurs
Burning sensation
who is more prone to denture stomatitis
Patients with a depressed immune system, history of head and neck radiation, and antibiotic use.
ill fitting dentures cause?
EpulisFissuratum
cleaning dentures/ RPD
clean dentures after each meal and change cleaning solutions daily
Why leave dentures out at night?
Rest for the tissues (to help prevent denture induced oral lesions)
a pt can be unaware of what type of denture induced oral lesions?
chronic mucosal lesions, which are often asymptomatic.
why should the edentulous pt conduct IO/EO exam daily?
Tissue changes can be indicators of oral cancer or other disease. Conduct IO exam thoroughly with adequate lighting.
A bony protuberance generally located on the buccal aspects of maxilla and/or mandible.
Exostosis
bony mass generally located on the lingual in the region of the premolars.
Torus mandibularis
bony enlargement located over the midline of the palate.
Torus palatinus
when do major bony changes occur after a pt becomes edentulous
within the first year
The bone after a patient becomes edenutlous
After teeth are removed, the alveolar bone which formerly supported the teeth undergoes resorption.
removable prosthesis that replaces the entire dentition and rests on the mucosal-covered alveolar ridge.
Tissue supported complete denture
a complete dental prosthesis that is supported in part or whole by one or more dental implants. The denture itself is not an implantable device.
Implant denture
Removable; rests on one or more remaining natural teeth. Also called an overlay.
Overdenture
fabricated for placement immediately following the removal of natural teeth. After approx. 6 months when soft tissue and bone has healed, the denture must be remade, relined, or rebased to fit.
Immediate denture
what type of fluoride should be used during ortho placement and treatment?
Varnish
what are Subperiosteal dental implants made of?
titanium or vitallium
Custom-fabricated framework of metal that rests over the bone of the mandible or maxilla, under the periosteum: complete arch or unilateral.
Subperiosteal dental implants
implant most commonly used for dentures
Transosseous Implants (Transosteal)
A dental implant that penetrates both cortical plates and passes through the full thickness of the alveolar bone.
Transosseous Implants (Transosteal)
Transosseous Implants (Transosteal) is also known as
a mandibular staple implant or staple bone implant.
Transosteal made of
stainless steel, ceramic-coated materials, and titanium alloy
MOST COMMON DENTAL IMPLANT
Endosseous (Endosteal) Implant
implant placed within the bone to replace a single tooth or provide support for the replacement of complete or partial loss of teeth. These are placed fully within the bone
Endosseous (Endosteal) Implant
osseointegration is used in
– used in endosteal implants, maing tooth replacement successful
endostea implants made of
primarily plasma-sprayed titanium
Endosteal implants may be placed in
May be placed in one or two phases
the implant is placed immediately following the extraction of the tooth it will replace
immediate placement of endosteal inplants
the support, body or fixture is placed in bone during the first surgical step and left covered by a periodontal flap for several months while the implant bonds with the bone. The abutment post is then exposed through the soft tissue at second-stage surgical procedure. Placement of the crown follows
Two phase steps of ednosteal implant placement
patients contraindicated for dental implants
Pregnancy debilitation Recent radiation therapy to the affected part of the oral cavity Uncontrolled diabetes Alcoholism or heavy alcohol intake Substance abuse An immunosuppressive disease or medication Anticoagulant medication Psychosis or paranoia
what irrigation do we use for a pt with implants
Chlorhexadine can be used as a rinse or with an oral irrigator
What fluoride should be used for a pt with implants
Neutral sodium fluoride. Avoid acidic fluoride
if a pt has natural teeth and implants
they should use an at-home fluoride treatment.
biofilm around implant
Biofilm microorganisms around implants with healthY tissue have been shown to be similar to the flora around natural teeth.
Probe used for implants
Use a smooth, plastic probe with a round end
refers to the infusion of connective tissue cells between the implant body and surrounding bone. It indicates failure of osseointegration. Mobility is evident.
Fibrous encapsulation
reversible bacterial infection in the soft tissue similar to gingivitis. Mild color change with bleeding may be present.
Initial Stage-Mucositis
Inflammation has reached the level of the bone. Edema or hemorrhage is present in the surrounding tissues. Exudate may or may not be present, and probing depths are increased.
Secondary Stage Periimplantitis
inflammation present but no mobility. Consult surgeon if no response to tx in 2 weeks.
Ailing Implant .
inflammation present. Bone loss has occurred and continues. Mobility faintly noticeable.
Failing implant
Evident mobility. Radiographic changes are evident, often showing a vertical bony defect. Refer pt. immediately back to surgeon.
Failed implant
dental hygiene considerations when cleaning an implatn
Always use plastic instruments!
Do not use an ultrasonic
Confine manual instrumentation to the prosthesis and supragingival area of the abutment
Only non-abrasive prophy paste is used if any at all
a healthy implant shows
No pain or discomfort reported by the patient
No mobility
No bone loss or periimplant radiolucency in a radiograph
No clinical signs of periimplantitis. Gingiva should be firm with no edema.
No bleeding or increased probing depths on gentle probing performed with a rounded, smooth plastic probe.
a pt that is a good candidate for dental implants will have
no systemic conditions that interfere with healing or implant acceptance
refers to direct structural and functional union between the implant and healthy living bone. It indicates successful placement of the implant. No mobility is evident.
osseointegration
A series of customized transparent and removable aligners utilized in orthodontic therapy to align or straighten teeth
Aligner system
curved wire positioned in the brackets around the dental arch and held in place by elastomers or ligatures
Arch wire
attachment that is bonded to the enamel for the purpose of holding the arch wire
bracket
elastoplastic ring or latex elastic used to hold an arch wire in a bracket wing
elastomer
a removable plastic and wire appliance used to stablilize teeth; may be modified for special applications during or after orthodontic therapy
Hawley retainer
An orthodontic appliance, fixed or removeable, used to maintain the position of the teeth following corrective treatment
retainer
prosthetic replacement for prematurely lost primary teeth to prevent closure of the space before eruption of the permanent successors
space maintainer
a tooth of an implace used for the support or retention of a fixed or removable prosthesis
abutment
dental prosthesis that replaces the entire dentition and associated structures; may be a complete maxilary denture or a complete mandibular, or both
complete denture
an inflammation of the oral mucosa that bears a complete or partial removable dental prosthesis, typically a denture
denture stomatitis
a replacement for one or more missing teeth that is securely cemented to natural teeth and dental implant abutments that furnish the primary support for the prosthesis; also called a fixed prosthesis or bridge
fixed partial denture
dental prosthesis that supplied teeth and/or associated structures in a partially edentulous jaw and can be removed and replaced at will
removable partial denture
a prosthesis used to close a congenital or acquired opening, such as for a cleft palate, an area lost because of trauma, or after surgery for removal of diseased areas
obturator
Capable of existing in harmony with the surrounding biologic environment
bicompatible
layer of fibrous connective tissue between the implant and surrounding bone. Also called fibrous integration, indicative of failed osseointegration
fibrous encapsulation
a procedure that attempts to regenerate lost periodontal structures
guided tissue regeneration
the direct attachment or connection of osseous tissue to the inert alloplastic material without intervening connective tissue
osseointegration
destructive inflammatory process of the periodontal tissues around an implant charactersized by progressive bone loss in addition to soft tissue inflammation with hemorrhage and/or exudate; similar to periodontitis in a natural tooth
peri-implantitis
a common titanium allow used for dental implants that contains 6% aluminum to increase strength and decrease weight and 4% vanadium to prevent corrosion

anodontia
bony projection extending beyond the normal contour of a bony surface
exostosis
