New Complete Dentures
Every patient is eager to see what their new dentures (or false teeth) look like, and for good reason. But how can you judge if it's really going to be grand?
Coco Chanel, the world-renowned fashion designer, once said that if you notice a lady's clothes, she's poorly dressed; if you notice the lady instead, she's impeccably dressed. That same philosophy can help prosthodontics wearers to assess for themselves what looks right.
During the wax try-in appointment, when you're "fine-tuning" your replacement teeth, you may be tempted to peer at them while holding them in your hands, or evaluate what you see in the mirror through bifocals. While this "view" will give you an idea of the construction of your new denture, it's not how other people will see it.
What goes into creating good complete dentures?
Your prosthodontist can create a rugged or delicate, masculine or feminine, assertive or passive, youthful or mature look. Youthfulness can be achieved by a curved smile line, showing the two front teeth more than those on each side, and having a darker translucent edge on those front teeth. False teeth can be brought down where they are more visible and placed further forward to plump out a thin upper lip. If teeth are arranged evenly in a flat line, it makes a person look older.
Any of these qualities can be realized in a new denture, but they won't show while it is in your hand. A good denturist invests time and all his care to make your denture look best, in your mouth, where it belongs. Look at your dentures in the mirror from a conversational distance, while you talk or smile. And if your friends don't notice it, your prosthodontist has done a good job.

Avoiding Conventional Partial Dentures and False Teeth
Precision and semi-precision partial dentures, like conventional partial dentures, replace missing natural teeth with artificial teeth. However, the means by which they are retained in the mouth is different than a conventional clasp prosthesis.
To better understand these partial dentures types, it is best to first review the basics of conventional partial denture clasps.
How Conventional Partial Denture Clasps Function
Most partial dentures are usually kept in place by clasps. These are thin finger-like projections of special resilient metal alloy, or, in certain cases, plastic or plastic-like materials.
- Clasps rest on and around certain remaining natural teeth so that their ends extend into narrow areas below a gentler bulge on the tooth. Sometimes it is necessary to shape a tooth or make a crown for a tooth or teeth in order to develop the right amount and relationship of undercut and bulge for retention.
- When a partial denture is placed in the mouth, clasps gently spring over a tooth bulge and rest in a relaxed state within an undercut.
- A partial dentures are held in place during normal eating, speaking and other activities because clasps resist springing back over tooth bulges.
- Clasp resistance to removal is not great enough to prevent a person from comfortably removing their partial denture whenever they choose.
The Problem With Conventional Denture Clasps
Despite numerous successful conventional clasp designs, they do have some drawbacks.
- Clasps may at times become visible. Often, this is unavoidable and usually is not objectionable. However, for some individuals, the show of clasps is simply not acceptable because of personal circumstances and compromised appearance.
- Certain partial false teeth may function better with retentive means other than conventional clasps.
- Remaining natural tooth structures may be inadequate to accommodat conventional clasps. Therefore, dental crown or crowns may need to be fabricated to correct these deficiencies.
Semi-Precision and Precision Partial Dentures -- Viable Alternatives
Alternatives to conventional clasp partial dentures fall into two categories, both of which have no clasps to show.
- Semi-precision partial dentures are retained in the mouth by means of mechanical interlocking components. A specially-shaped extension of the partial denture fits into or onto a complementary receiving area or projection of a natural tooth that has been crowned.
The components fit snugly and consist of a semi-rigid metal-to-other-surface interface, which may also be metal or some other resilient material such as nylon.
- Precision partial dentures are similar to the semi-precision type except that the mechanical interlocking components are manufactured to extremely high tolerances and are held together by precise alignment and a rigid metal-to-metal frictional interface of components.
Advantages of Semi-Precision and Precision Partial Dentures
- A cosmetically-enhanced partial denture as compared to conventional partial dentures
- No show of metal clasps
- Blends in with the conformity of remaining natural teeth
- Functions with a more even pressure on remaining natural teeth than conventional partial dentures
Disadvantages of Semi-Precision and Precision Partial Dentures
- Semi-precision partial dentures are the most costly to fabricate
- Usually some natural teeth need to be crowned
- More difficult to fabricate and adjust
- Some components may need periodic replacement
Which Type of Partial Denture Is Best?
Every patient has unique oral health needs that are best determined by a licensed dentist after a thorough examination.
