Summary
Oligodontia, the congenital absence of many teeth, can be effectively managed with implant-supported prostheses. This interdisciplinary approach requires careful planning and patient motivation for successful long-term outcomes.
Area of Science:
- Dentistry
- Genetics
- Oral and Maxillofacial Surgery
Context:
- Oligodontia is a rare genetic condition characterized by the congenital absence of at least six permanent teeth.
- This condition can lead to significant dental abnormalities, affecting facial growth, mastication, and phonation.
- Familial hypodontia is often linked to specific gene mutations or polymorphisms.
Purpose:
- To evaluate the management of 30 patients diagnosed with oligodontia.
- To assess the efficacy of implant-supported dental prostheses as a rehabilitation method.
- To analyze the clinical and paraclinical data for orthognathic and implant rehabilitation planning.
Summary:
- The study analyzed 30 patients (6-20 years old) with an average of 15 missing teeth, including frequent agenesis of third molars, second molars, and maxillary incisors.
- Treatment involved orthognathic surgery (46.7%), bone grafting (56.7%), and implant insertion (46.7%) with a total of 155 implants.
- Rehabilitation with implant-supported prostheses was successful, necessitating an interdisciplinary team approach.
Impact:
- Implant-supported prostheses offer a viable solution for restoring function and aesthetics in oligodontia patients.
- The success of treatment hinges on a multidisciplinary approach involving surgeons, orthodontists, dentists, and prosthodontists.
- High patient and family motivation is critical for achieving optimal and lasting results in managing this complex condition.

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.
