RPD Review Learning Activity.docx + 15 implant questions -
1. what material are most dental implants and abutments?: Implant: Titanium Grade 4 = Pure Titanium
Abutment: Titanium Grade 5 = Titanium alloy
2. what implant shape is best for low density bone?: Tapered Screw ?
3. If you have deficient keratinized tissue in the area, what do you do before placing an implant?: complete a
graft to get keratinized tissue
(Incision should always maintain attached tissue on facial/buccal, Minimum of 2mm Circumferentially Required for Lon
Term Crestal Bone Stability)
4. type of microsurfaces on implants (degree of roughness of implant, aid in osteointegration): additive or
subtractive
additive:
1. HA coating (hyaluronic acid)
2. TPS (titanium plasma technique)
3. Anodization (to Thicken titanium oxide surface)
subtractive:
1. SLA (Sand-blasted w/ Large grit and Acid)
2. Resorbable Blast Media (RBM): Blasting w/ abrasive material, like silicon or HA
3. Lasers
5. What is Platform Switch?: •Abutment is narrower than implant at the connection
• Reduces bone loss
• Allows greater volume of soft tissue at implant-abutment interface for better esthet- ics
6. How to determine the diameter / size of healing abutments: Look at cervical diameter of tooth you're replacing
(On a CBCT, using the axial section, look at the CEJ of the contralateral tooth and measure it. This will tell you the
diameter of the healing abutment you need)

7. A guided circle approach for implants requires a : cervical guide
8. Which implant abutment connection is the best to seal off and prevent bac- terial contamination / Peri-
Implant Inflammation?: internal hex butt joint (~2-3 m¼ microgap)
9. (3) advantages of immediate implant technique placement: 1. preservation of bone and soft tissue architecture
2. shorter treatment time 3. esthetics (if anterior tooth)

10.4 indications for Small Diameter /Mini-Implants (1.8 - 2.9mm): 1. Overden- tures
2. Narrow Ridges where ridge-
augmentation
is contraindicated
3. Lower Incisors
4. LATERAL UPPER INCISORS
11.Major connectors (purpose + material): material = chromium cobalt alloy (rigid)
purpose =
1. unification of major parts of prosthesis
2. distribution of applied force to teeth/tissue
3. minimization of torque to individual teeth
A properly designed rigid major connector effectively distributes forces and reduces load while effectively controlling
prosthesis movement.
12.t/f: · Large, operable, bony prominences or tori should be removed to avoid compromise in the
location and design of the MAXILLARY MAJOR CONNECTOR: true
13.For maxillary major connectors, how far away should metal p gingival margins?: at leastarts be from
6mm to not disrupt blood flow (marginal g NEVER support an RPD) ingiva
should
14.All elements for maxillary major connectors should cross the palate at
angles: right
15.What is beading?: -used for maxillary major connectors only
-creates shallow groove on cast (0.5 - 1mm) outlining the maxillary major connector
16.When is a palatal strap usually used? What's the minimum width? :-
strap is a mx major connector usually only used for Kennedy Class 3
Palatal
-Need a minimum width of 8-10mm
