Exam 2: Implants in the Esthetic Zone
Terms in this set (30)
What are the 7 risk assessments to consider for esthetic implants?
1. Patient expectations
2. Height of lip line
3. Gingival biotype
4. Shape of teeth
5. Shape of edentulous space
6. Soft tissue anatomy
7. Bone anatomy
A _____________ lip line means a more difficult esthetic result.
T or F: Thinner gingival biotypes are preferred for an esthetic result.
Which is easier to manipulate? A thick or a thin gingival biotype?
What tooth shape is preferred for esthetic implant restorations?
Square (triangular teeth pose a risk for black triangles)
In what case is a high lip line easier to work with for an esthetic result?
Replacing 3 or more teeth
The highest risk for esthetically replacing soft tissue is when soft tissue for _____________ (how many) teeth needs replacement.
2 or more
How much soft tissue is preferred for an esthetic implant restoration?
____________ bone deficiencies pose the highest risk for esthetic implant restorations. _____________ deficiencies are less difficult to work with, but still not preferred.
How much vertical space is needed to restore with an anterior crown?
A crown + root fixed prosthesis requires how much vertical space?
A PIB prosthesis requires ______________ of vertical space.
An overdenture prosthesis requires ____________ of vertical space. A bar overdenture requires _____________.
17-20mm; 20mm or more
An implant should engage ___________ into the apical portion of the extraction site. From the gingival zenith to the bone crest, ___________ of abutment space is needed.
What is the best bone phenotype to work with?
What is the process for creating an esthetic implant restoration?
2. Surgical protocol
3. Tissue control
4. Capture tooth texture
5. Analyze occlusion
6. Capture tooth features
There are 5 factors to consider for esthetic results:***
1. Peri-implant tissue health
2. Harmonious scalloping
3. No open embrasures
4. Convex soft tissue contours
5. Balanced tooth dimension
What are the zirconia connector sizes for:***
Anterior FPD 1 pontic?
Posterior FPD 1 pontic?
Posterior FPD 2 pontics?
Full-arch implant FPD?
1. Anterior cantilever? 6mm2
2. Anterior FPD 1 pontic: 7mm2
3. Posterior FPD 1 pontic? 9mm2
4. Posterior FPD 2 pontics? 12.5mm2
5. Full-arch implant FPD? 16mm2
An angled screw channel (ASC) has an angulation of up to ______________.
There are 5 factors to consider for a predictable anterior restoration:***
1. Tooth position (coronal)
2. Gingival form (flat scallop)
3. Biotype (thicc)
4. Tooth shape (square)
5. Osseous crest (high)
What is the ideal distance between an implant and a natural tooth? What about between 2 implants?
What part of an anterior tooth should the implant be aligned with?
T or F: It is better to have a buccally-positioned implant.
False; palatal positioning spares the buccal bone
After a tooth extraction, how much horizontal and vertical bone width/height is generally lost?
What are some indications for immediate implant placement?
1. Intact facial coronal bone
2. Primary stability
3. Controlled forces
What are some indications for delayed implant placement?
1. Deficient facial coronal bone
2. Poor primary stability
3. Uncontrolled forces
T or F: Socket preservation PREVENTS physiologic ridge reduction after an extraction.
False; It LIMITS reduction
What are the 3 zones of an implant restoration?***
E: Esthetic zone (1mm sub-G)
B: Bounded zone (1-2mm apical to E zone)
C: Crestal zone (1-1.5mm immediately coronal to implant platform)
What are the designs and functions associated with the E, B and C zones?
Zirconia does not cause discoloration in tissue that is at least __________ thick, but titanium has been seen to cause visible discoloration.
