Study Notes
Prosthodontics Concepts
- Peri-implantitis can be caused by poor oral hygiene, smoking, and genetic predisposition.
Implant Retention
- Screw-retained implants offer the advantage of easier retrievability.
- A potential disadvantage of screw-retained implants is that the screw access hole can be problematic.
Bridge Design
- Using a cantilever design is not recommended for posterior regions.
- When one of the abutment teeth is tilted off-axis, a non-rigid connector is used.
Prosthodontics Definition
- Prosthodontics is the branch of dentistry concerned with the design and fitting of artificial replacements for teeth and other parts of the mouth.
Abutment Tooth Selection
- Teeth that should never be used as abutments for a bridge include endo-treated teeth.
- Compromised periodontal teeth are not ideal abutments due to their doubtful prognosis.
- Ideal abutment teeth have a root shape that is conical, tapered, and long.
Crown to Root Ratio
- The ideal crown to root ratio for an abutment tooth is 2:3 or 1:1.5.
- According to Ante's Law, the PDL surface area of the abutment teeth should be equal to or greater than the imaginary PDL surface area of the missing teeth.
- Violating Ante's Law can lead to a poor prognosis for the bridge.
Bridge Components
- The crown that attaches to the abutment in a dental bridge is called a retainer.
- The fake tooth in the center of a dental bridge is called a pontic.
- The tooth to which the bridge attaches is called an abutment.
- The component that connects the retainer to the pontic is called a connector.
Treatment Options
- Removable partial dentures are indicated when there are multiple missing teeth.
- An over denture is a type of treatment option that involves placing a denture over existing teeth.
Implant Complications
- Excess cement in a cement-retained implant can cause peri-implantitis.
- Peri-implantitis is different from periodontitis in that it occurs around implants rather than natural teeth.
