Summary
Ensuring artificial teeth adhere to denture bases is crucial. Current methods show uncertain efficacy, with 3D printing currently less reliable than traditional or milled denture teeth.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
- Prosthodontics
Background:
- Artificial tooth extraction from denture bases is a persistent challenge in both traditional and digital prosthodontics.
- Various chemical and mechanical treatments are used to enhance tooth retention, but their effectiveness is not fully established.
- Material incompatibility and poor copolymerization are key factors contributing to denture tooth failure.
Purpose of the Study:
- To provide an updated review on the adherence of synthetic denture teeth to denture base materials.
- To evaluate the efficacy of diverse methods used by dental technicians to improve tooth retention.
- To identify optimal denture base resin (DBR) and artificial tooth combinations for improved denture longevity.
Main Methods:
- Narrative review of existing literature on denture tooth adherence and retention methods.
- Analysis of chemical and mechanical treatments, including abrasion, laser treatment, and abrasive blasting.
- Comparison of retention and failure patterns across different fabrication methods: traditional, milled, and 3D-printed.
Main Results:
- Specific DBR and artificial tooth combinations show improved retention in heat-cured dentures after certain treatments.
- 3D-printed denture tooth-DBR combinations exhibit lower bond strength and less favorable failure modes compared to conventional methods.
- Milled and traditional denture fabrication methods currently offer more reliable tooth retention.
Conclusions:
- Further research is essential to determine optimal tooth-DBR combinations as new materials and fabrication techniques emerge.
- Advancements in additive manufacturing are needed to improve the reliability of 3D-printed denture teeth.
- Milled and traditional denture fabrication approaches remain the preferred choice for robust tooth retention.

01:12Bonding and Strength of Aggregate
146
The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...

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...
