Summary
Traumatic anterior tooth fractures, particularly in maxillary incisors, can be treated using homogenous bonding with donated teeth. This case study details a successful 18-year follow-up of this dental restoration technique.
Area of Science:
- Dentistry
- Dental Trauma
- Restorative Dentistry
Background:
- Anterior tooth fractures are common dental injuries, especially in maxillary central incisors.
- Homogenous bonding, using donated extracted teeth, is an alternative when tooth fragments are unavailable or unsuitable for reattachment.
- This technique offers a viable option for restoring fractured anterior teeth.
Observation:
- A case of a fractured maxillary central incisor treated with homogenous bonding is presented.
- The treatment involved the use of a donated extracted tooth for restoration.
- Long-term follow-up was conducted to assess the durability and success of the procedure.
Findings:
- The homogenous bonding procedure resulted in a successful restoration of the fractured maxillary central incisor.
- The restoration demonstrated excellent longevity, with a successful follow-up period of 18 years.
- This indicates the long-term viability and effectiveness of homogenous bonding in treating anterior tooth fractures.
Implications:
- Homogenous bonding is a predictable and durable treatment option for anterior tooth fractures.
- This technique can provide a long-lasting aesthetic and functional solution for patients.
- Further research into homogenous bonding could refine its application and long-term outcomes in dental traumatology.

Bonding and Strength of Aggregate
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...
Bonding in Metals
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.
Longitudinal Research
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Chemical Bonds
Atoms participate in a chemical bond formation to acquire a completed valence-shell electron configuration similar to that of the noble gas nearest to it in atomic number. Ionic, covalent, and metallic bonds are some of the important types of chemical bonds. Bond energy and bond length determine the strength of a chemical bond.
Types of Chemical Bonds
An ionic bond is formed due to electrostatic attraction between cations and anions. Often, the ions are formed by the transfer of electrons from...
Covalent Bonds
Overview
Cohesion
Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.
