1. Look at figures 5 & 6 from Dr. Bidra's article. Why does he advocate a cross sectional matrix in measuring prosthetic space?
• The matrix technique helps to determine accurately if there is adequate space directly below the denture where the implant and prostehtic component would be located. Failure to correctly assess the amount of space has the potential to encroach on the neutral zone.
• The sectional matrix can also provide information on the amount of horizontal prosthetic space, which can be helpful in choosing the appropriate type of attachment system
2. ____ is one implant variable that will impact prosthetic space.
• Height of the abutment
• Polished collar of the implant
• Additional height of the attachment component that seat over the abutment
• Thickness of the acrylic to encase the abutment attachment adequately
3. Inadequate prosthetic space results in _____?
• Problems such as over contoured prosthesis
• Compromise in the neutral zone & tongue space
• Fractured prosthetic teeth or Prosthesis
• Excessive OVD
• Additional need for corrective surgeries
• Impede the fabrication of the prosthesis
4. The amount of prosthetic space available is dictated by ____?
• Position of planned prosthetic teeth
• Design of the prosthesis
• Establishment of proper occlusal plane & OVD
5. According to Dr. Bindra (and many others), ------------ is the standard of care when treating an edentulous mandible.
Overdenture retained by 2 implants
6. From table 6 of Dr. Pan's article, _____ is one reason the patients might prefer a mandibular denture retained by implants.
• Provide stability of the denture which manifests in social and psychological impact such as:
i. Ability to fully laugh
ii. Speak easy in denture
iii. Understanding from people during speaking
iv. Better facial appearance
v. Visit family with your dentures
vi. Visit friends and go to parties with denture
7. ____ is one aspect of additional treatment planning that must be followed when treatment planning implants for an overdenture.
• Amount of prosthetic space
• Number of implants
• Choice of prosthetic design (bar or individual attachments)
• Position of implants
• Choice of attachment system
8. Table 5 from Dr. Pan's article lists several questions that were asked of patients. _____ is one example of the benefit of an implant overdenture compared to a previous conventional CD.
• Decreased pain under the mandibular denture
9. In Dr. Scherer's article, Figure 4 is really important. Why?
This is an image of fit-checker with areas of show thru marked in blue. The areas of show through were then enlarged the recesses. This is important because you want to make sure the retentive component will be able to fit in the recesses and not bind or move also allowing the components to be put into the denture with acrylic placement to secure them.
10. I read the article by Dr. Mericske-Stern. Even though it is 16 yo article, it had some great points to make about determining the number and positions of implants for the edentulous. I will keep this handy for reference when talking to edentulous patients about utilizing implants.
1. ___ is a reason that a surgical stent is utilized in a palatal torus removal surgery?
aid in patient comfort and prevent hematoma formation
2. Why is the historical technique of interseptal alveoplasty not as common in modern prosthetic treatment?
• Historically, interseptal alveoplasty offers an alternative technique to remove large bony undercuts while maintaining vertical ridge height.
• However, this method should be used judiciously while maintaining adequate ridge width to accommodate possible future implant placement.
3. Give one example of an unsatisfactory anatomical presentation and a surgical intervention to address this concern.
• Excessive maxillary tuberosity. This compromises the vertical space needed for prosthesis fabrication. The surgery required is a maxillary tuberosity reduction. A good rule of thumb is if a dental mirror passes freely between the tuberosity and the retromolar pad then that is adequate space needed for prosthesis fabrication.
4. Dr. Ephros states that the purpose of preprosthetic surgery is t
o facilitate the fabrication of prostheses of the improve the outcome of prosthodontic treatment.
1. What are the two broad types of intracapsular disorders?
• Disorders involving the muscles
• Disorders involving the TMJ
2. ----- and ------ are the reasons that the disc and condyle move together.
Morphology of the disc and interarticular pressure
3. Briefly summarize the function of the ligaments in the TMJ.
• The ligaments in the TMJ act as a guide to stabilize and control the types of movement in the TMJ. They restrict border movements while allowing the functional movements.
• The collateral ligaments attach the disc to the condyle medially and laterally and restrict the medial and lateral movement of the disc but allow anterior and posterior movements.
• The range of motion of the disc is also controlled in the anterior and posterior direction by the inferior retrodiscal ligaments which restrict the anterior movement of the disc.
• The anterior capsular ligament limits the posterior rotation of the disc.
4. Dr. Solow classifies anterior guidance into four categories. Choose a category and describe the excursive contacts for that category.
• Class 1: Lateral excursion contact solely on the canines and protrusive excursive contact is solely on the central incisors.
• Class 2: lateral excursion contact is first on the canines and then on the central incisors. Protrusive excursive contacts is solely on the central incisors or first on the canines and then on central incisors.
i. Used when periodontal support is compromised or if the patient notices a sore tooth from severe bruxism
• Class 3: All excursive contacts is solely on the canines. "Michigan Splint"
i. Used when anterior open bites or periodontal compromised incisors. These incisors should touch at the end of protrusive excursive movements to prevent extrusion.
• Class 4: where there is unacceptable occlusal design with missing posterior teeth contact or posterior teeth contact in excursions that can prevent anterior teeth contact.
5. The separation of the posterior teeth by the anterior teeth during mandibular excursion ------ elevator muscle hyperactivity.
6. What is the definition of mutually protected occlusion?
• Posterior teeth prevent excessive contact of the anterior teeth in MI
• Anterior teeth disengage the posterior teeth in all mandibular excursive movements
• Posterior contacts should be across each tooth and evenly distributed
7. Why is it important for an occlusal device to cover all the teeth in the arch?
• This prevents the overeruption of unopposed teeth from the segmental arch coverage and minimizes the pressure on each contacting tooth
8. What are the three criteria that an occlusal device must fulfill?
1. All teeth should contact evenly on the occlusal device in the arc of closure when the mandibular condyles are physiologically seated in their respective fossae
2. Anterior teeth should not contact more heavily than posterior teeth
3. Anterior teeth should smoothly separate posterior teeth during all excursive movements
9. Bruxism is one reason to fabricate an occlusal device.
• Myofascial pain is another
• Attrition from bruxism
1. --------is one option when preventing or mang tooth wear.
2. What is the difference between erosion and attrition
Attrition is caused from tooth against tooth wear, with facets appearing with those teeth in guidance. Erosion is caused by frequent consumption of acids or eating disorders

1. Dr. Jerbi describes 6 steps in trimming the cast. What do these 6 steps represent?
a. Step 1: Cutting away the part of the crown that is visible above the gingival 1/3 line
b. Step 2: Removal of the entire crown of each tooth. Recess the ridge to the depth of the length of the anatomic crown.
c. Step 3: Flat cut across the ridge that extends the labial depth of the length of the crown to the junction of the gingival and middle 1/3 of the labial surface of the ridge. (Collapse of the labial gingival tissues toward the alveolus)
d. Step 4: Flat cut across the ridge from the center of the ridge to the midwidth point of cut in step three. (Contour of the labial surface of the ridge)
e. Step 5: The incisive papilla in its collapsed position so that the denture will not place undue pressure on the underlying structure
f. Step 6: Contour and smooth the ridge from the lingual side to the junction of the middle vestibular 1/3s of the labial side of the ridge. The collapsed position of the incisive papilla is sculptured on the crest of the ridge. (Smooth tissue receptive inner surface of the denture if bone must be removed for mechanical, biologic, or esthetic requirements)
