Summary
This review examined occlusion schemes for removable partial dentures (RPDs). Limited evidence exists, with recommendations primarily based on expert opinion for harmonious, balanced RPD occlusion.
Area of Science:
- Dentistry
- Prosthodontics
- Dental Occlusion
Background:
- Extensive research exists on complete denture occlusion.
- Data on occlusal schemes for removable partial dentures (RPDs) is less clear.
- This review focuses on the limited literature concerning RPD occlusion.
Purpose of the Study:
- To investigate the dental literature regarding occlusal schemes specifically for removable partial dentures (RPDs).
- To identify and synthesize available recommendations for RPD occlusion.
- To highlight the evidence base, or lack thereof, for current RPD occlusion practices.
Main Methods:
- Conducted a comprehensive PubMed search using various keyword combinations related to RPD occlusion.
- Screened titles and abstracts to identify relevant articles.
- Included a hand search of relevant textbooks to supplement literature findings.
Main Results:
- Only 4 articles provided specific recommendations for RPD occlusion after initial screening.
- The identified recommendations were based on expert opinion, not empirical evidence.
- Textbook reviews yielded no evidence-based references for RPD occlusal schemes.
Conclusions:
- RPD occlusion should promote physiological harmony and distribute functional stress.
- Centric occlusion should feature bilateral posterior contacts without deflective contacts.
- Balanced occlusion or canine-protected occlusion are recommended for RPDs, with bilateral balanced occlusion suggested when opposing complete dentures.

01:21Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Veneer refers to a thin sheet of wood, typically produced to a thickness of about one-eighth of an inch or less. This material is crafted through various methods, the most common being rotary cutting. In this process, a log is mounted into a large lathe and spun against a knife edge, peeling off a continuous strip of wood as the knife penetrates deeper into the rotating log, creating a rotary-cut veneer.
Other veneering techniques include plain-slicing, quarter-slicing, and rift-slicing. These...

01:26Assessment of the Mouth
702
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
