Summary
This study evaluated direct composite resin restorations for worn teeth over 5.5 years. The template-guided technique showed good overall quality, with minor issues treatable by polishing.
Area of Science:
- Restorative Dentistry
- Dental Materials
Background:
- Erosive tooth wear necessitates durable and aesthetic restorative solutions.
- Direct composite resin restorations offer a minimally invasive approach for extensive dental rehabilitation.
Observation:
- A case series of six patients with severe erosive tooth wear (75 posterior teeth) underwent full-arch reconstruction.
- A wax-up-based template technique was employed for direct composite resin restorations to ensure anatomical accuracy and function.
- Patients were re-assessed after an average service time of 5.5 years using United States Public Health Service criteria.
Findings:
- Overall restoration quality was rated as good, with predominantly 'alpha' and 'bravo' scores.
- Deterioration was noted in marginal quality, discoloration, surface texture, and anatomy compared to 3-year follow-up.
- Marginal impairments were successfully resolved through polishing.
Implications:
- Template-guided direct composite resin restorations present a viable treatment option for erosive worn dentitions.
- This technique demonstrates clinical efficacy for at least a 5.5-year service period.
- Regular maintenance, including polishing, is crucial for preserving the longevity and aesthetics of these restorations.

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.

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...
