Summary
Orthodontic extrusion, or forced eruption, offers a less invasive alternative to traditional crown lengthening surgery for restoring teeth and developing implant sites. This technique preserves bone and improves aesthetics, making it a valuable option when planned carefully.
Area of Science:
- Periodontology and Implant Dentistry
- Orthodontics
- Restorative Dentistry
Background:
- Crown lengthening is crucial for periodontal health and restoration success when biological width is invaded or ferrule effect is lacking.
- Optimal peri-implant tissue architecture is essential for esthetics and function, often requiring site development before implant placement.
Purpose of the Study:
- To provide comprehensive guidance on the clinical use of orthodontic extrusion (forced eruption).
- To review and discuss current literature on forced eruption for crown lengthening and implant site development.
- To maximize patient outcomes for dental restorations and implant procedures.
Main Methods:
- Systematic review and discussion of available literature on orthodontic extrusion.
- Comparison of forced eruption with traditional crown lengthening surgery.
- Analysis of appliance types (fixed and removable) and patient compliance factors.
Main Results:
- Forced eruption offers advantages over traditional crown lengthening, including bone preservation, improved esthetics, and less impact on adjacent teeth and crown-to-root ratio.
- It serves as a non-invasive technique for increasing clinical crown length, correcting periodontal defects, and developing implant sites.
- Patient compliance is a key factor, particularly for removable appliances.
Conclusions:
- Orthodontic extrusion is a valuable adjunct for crown lengthening and implant restorations.
- Careful case selection based on indications and contraindications (e.g., inflammation, ankylosis, root fracture) is essential.
- Further research is needed on the long-term stability of orthodontically extruded teeth and their supporting tissues.

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...

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...
