Most unacceptable types of dentures - nesbit tooth prosthesis

Temporary dental crown and acrylic resin pivot

This type of crown made from acrylic resin, is in use until a definitive, porcelain or PFM (porcelain fused to metal) crown can be fitted. This period should not exceed 15 days, which is more than required to fit a permanent crown.

No matter how well it was done, the temporary crown has no quality. Do be untempted by the price and do be unfooled. It was not made to last, and it does not have the perfection, hardness, colour stability or biocompatibility of a true fixed dental crown.

Nesbit denture, Nesbit rpd, Nesbit partial, Nesbit tooth prosthesis

Unilateral removable prosthesis with one or more teeth and clasps at both ends

Also known as bridge with retentive clasps, nesbit tooth prosthesis, or Nesbit rpd. This is a type of prosthesis that is extremely dangerous to use.

Because of its small size, it can easily be swallowed or become lodged in the trachea. It seems very tempting to have a prosthetic tooth in the acrylic prosthesis limited to only one side of the mouth, specially when there are no missing tooth / teeth on the other side. Don't be lured by the nesbit low price.

In fact, it is what it seems, completely wrong. The removable denture should be always bilateral, it should extend to the other side of the arch to give it dimension, stability and retention. If you want to visualize images on this, please search for the term "nesbit partial or denture", which is the term by which they are known.

Usually, a case like this is ideal for a dental bridge work, with all the superior advantages of the fixed partial denture.

Removable partial denture without occlusal rests (vertical stop)

All removable partial dentures in acrylic or silicone are prostheses that sit on the gum, without any support from remaining teeth still present in the mouth. This fact accelerates bone loss and consequent degradation of oral health conditions. It decreases the longevity of those teeth, complicating or compromising the future possibility of prosthetic quality restorations.

The use of this type of denture is only temporarily justified, whilst the person waits for the undertaking of a good quality permanent denture.

Unfortunately, people's economic status has conducted them to use this kind of provisional prosthesis for much longer periods than they were designed.

These negative factors are even greater in flexible dentures. The characteristic that makes them alluring is the elasticity, which contributes to the damage of the alveolar bone much more than with a rigid acrylic prosthesis.

Acrylic complete denture with hollow palate surface

The upper denture can fit in many ways, among which by vacuum formed between the palate and the denture. Sometimes has been created a space in the denture palate with a heart-shape or another, intended to increase such vacuum effect. It is inappropriate, unnecessary and dangerous because it promotes the mouth deformation at palate level and the appearance of tumours. The proper procedure is to seal the end of the prosthesis in the area of the Fovea Palatini. A slight groove is sufficient to obtain a perfect seal.

Fake veneers don't resolve your aesthetic problems. You're the one fooling yourself. You should always look for long-lasting cosmetic dentistry.
