UTHSC SPRING 2024 D3 PERIO EXAM 2 MEGA SET QUESTIONS
WITH COMPLETE VERIFIED ANSWERS ALREADY PASSED
What should we consider when determining the success of an implant?
. Criteria is variable
. the original treatment plan is performed as intended without complications
. all implants that were placed remain stable and functioning without problems,
. peri-implant hard and soft tissues are healthy.
. patient and treating clinicians are pleased with the results.
What are the criteria for a successful implant that were established in 1986?
. Immobile implant
. No radiolucency around dental implants
. <0.2 mm annual loss of marginal bone level
. No persistent pain, discomfort or infection.
. Success rate of 85% at the end of a 5 year observation period and 80% at the end of a
10 year
What is the gauge for implant survival?
. Implant remains in place at the time of evaluation.
. Non-functional implants should not be considered for survival rate
What are the two types of implant complications?
1. TECHNICAL COMPLICATIONS
2. SURGICAL & BIOLOGICAL COMPLICATIONS
TYPES & PREVALENCE OF IMPLANT COMPLICATIONS: TECHNICAL
1. fracture of veneers (13.2% after 5 years).
2. loss of the screw access hole restoration (8.2% after 5 years).
3. abutment or occlusal screw loosening (5.8% after 5 years).
4. abutment or occlusal screw fracture (1.5% after 5 years and 2.5% after 10 years).
technical implant complications: fracture
,. Partially edentulous restorations (1.5%)
. completely edentulous arches (0.2%)
. ALL FRACTURES:
-commercially pure,
-3.75-mm diameter
-threaded implants
What are the risk factors for implant failure?
. Smoking
. Diabetes
. Periodontal disease
What are the different kinds of implants?
-machined surfaces
-external hexagonal connection
T/F prevalence and type of complications associated with the newer implant
designs may be different
True
SURGICAL COMPLICATIONS to implant placement
. Bleeding
. Damage to adjacent structures
. Injury to nerves
. Iatrogenic jaw fracture
POST-OPERATIVE COMPLICATIONS to implant placement
. Hematoma
. Infection
What causes the rate of Hemorrhage?
. Diameter of the blood vessel.
How can we stop hemorrhage?
. Apply pressure or suture the hemorrhaging vessel.
. Cauterizing (Except: floor of the mouth or posterior maxilla).
T/F Excessive bleeding can lead to airway obstruction
True
,Hemorrhage
. Post-operative bleeding (PO instructions - normal expectations).
. Medications that increase tendency of bleeding (consult medical practitioner).
Hematoma
. Submucosal or subdermal bleeding into the connective tissues.
. Larger hematomas susceptible to infection: Medically compromised individuals.
Prescribe antibiotics.
Why is Massive internal bleeding in the highly vascular region of the floor of the
mouth (displace the tongue and soft tissues of the floor of the mouth) so
dangerous and how do we treat it?
It can cause Upper airway obstruction
- Airway management
- Surgical intervention to isolate and stop the bleeding
What can cause neuropathy?
Injury during drilling
What can a neuroma formation result in?
A. Hypoesthesia
A. Hyperesthesia
If a diagnosis is established and treatment is rendered within the first ___ hours,
a high percentage of successful outcomes can be achieved
36 hours
Lateral transpositioning of the inferior alveolar nerve
- Almost 100% incidence of neurosensory dysfunction immediately Post-OP.
- Approximately 50% of neurosensory changes are permanent
What causes Implant Malpositioning?
. Poor treatment planning before surgery,
. Poor communication between the implant surgeon and the restorative dentist.
. lack of surgical skills,
. Implant angulation
Implant Malpositioning: Apicocoronal position
, - metal collar, insufficient prothetic space).
- Difficult access to hygiene
Implant Malpositioning: Buccal-lingual position
Ridge lap
What are the minimum distances between implants and other structures?
- IAN: 2mm
- Implant - tooth: 1.5mm
Implant - Implant: 3-4mm
What does biologic width invasion cause?
bone loss
What complications are cantilevers predisposed to?
- Biologic (i.e., bone loss)
- Mechanical (i.e., screw loosening, screw fracture, and implant fracture)
- Difficulties with hygiene
What are some adjacent vital structures that implants can be malpositioned into?
- Adjacent tooth root, PDL, tooth nerve.
- Inferior alveolar nerve, mental foramen (Paresthesia, hypoesthesia, hyperesthesia,
dysesthesia, or anesthesia)
- Maxillary sinus or nasal cavity
What helps us minimize complications when planning implants?
- CBCT scans (zone of safety)
- Surgical guides
- Radiographic guides
Why would someone need alveolar ridge augmentation?
Deficient alveolar ridge (developmental defects, periodontal disease, tooth loss, or
trauma).
What procedures can we do to help repair a deficient alveolar ridge?
. Autogenous bone harvesting and grafting,
. Guided bone regeneration, and sinus bone augmentation
Autogenous Bone Grafting
