Single-tooth implants and their role in preserving remaining teeth: a 10-year survival study
The International Journal of Oral & Maxillofacial Implants
|April 23, 1999
Summary
Dental implants effectively replace single missing teeth, preserving adjacent natural teeth. This 10-year study shows high implant survival and minimal complications, protecting surrounding dentition from restorative trauma.
Area of Science:
- Dentistry
- Prosthodontics
- Dental Implantology
Background:
- Using natural teeth as abutments for dentures can lead to irreversible damage.
- Dental implants offer a supportive solution for tooth replacement without compromising adjacent teeth.
Purpose of the Study:
- To evaluate the survival rates and prosthetic complications of single-tooth dental implants over a decade.
- To assess the condition and survival of teeth adjacent to these implant restorations.
- To determine the role of implants in preserving intact teeth and avoiding further abutment use.
Main Methods:
- A retrospective analysis of 99 patients with 116 single-tooth implants and 112 prostheses placed between 1988 and 1998.
- Examination of implant survival, prosthetic complications, and the status of adjacent teeth.
Main Results:
- Implant survival rate was 97.4% over 10 years, with only 3 implant failures.
- Prosthetic complications were minimal, including crown loss, screw loosening, and cement washout.
- Of 196 adjacent teeth, 79.6% remained intact or minimally restored, with very few requiring new restorations or extraction.
Conclusions:
- Single-tooth dental implants demonstrate favorable long-term survival and low complication rates.
- Implants effectively preserve adjacent natural teeth, preventing the need for them as abutments.
- This approach is crucial for maintaining healthy dentition during prosthodontic therapy.

01:15Teeth
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 and...

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 grinding food.
