Summary
Removable partial dentures (RPDs) are common, but many lack dentist design input and rests. Non-metal frameworks are frequent, indicating evolving patient needs and variable prosthodontic care standards.
Area of Science:
- Prosthodontics
- Dental Materials Science
- Public Health Dentistry
Background:
- Limited current demographic data exists on removable partial denture (RPD) prevalence and types.
- Understanding RPD patterns is crucial for prosthodontic literature and patient care.
Purpose of the Study:
- To investigate tooth loss patterns in patients receiving RPDs in eastern Wisconsin.
- To analyze the characteristics and design of RPDs fabricated in the region.
Main Methods:
- Analysis of 1502 digital cast images from 5 dental laboratories.
- Investigator assessment of RPD details including Kennedy Classification and major connector type.
- Descriptive statistics and Fisher's exact test for data analysis.
Main Results:
- Kennedy Class I RPDs were most frequent (38.4%).
- Over 40% of RPD prescriptions lacked dentist design input; 1 in 5 RPDs had no rests.
- Acrylic resin or flexible frameworks were used in one-third of RPDs.
Conclusions:
- RPDs remain a prevalent prosthodontic treatment in eastern Wisconsin.
- Non-metal RPD frameworks are common and often lack rests, suggesting evolving treatment approaches.
- Findings highlight a changing partially edentulous population and variable adherence to standard prosthodontic care.

01:01Dosage Regimens: Partial Pharmacokinetic Parameters
It is not uncommon for complete drug pharmacokinetic profiles to remain elusive in pharmacokinetics. This necessitates certain educated assumptions by pharmacokineticists to determine appropriate dosage regimens without comprehensive pharmacokinetic data from animal or human studies. One prevalent assumption is setting the bioavailability factor, denoted as F, to 1 or 100%. This assumption caters to the scenario where a drug doesn't achieve full systemic absorption, resulting in the patient...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
