Substance-Gain Extrusion Technique (SGET) in Combination With BOPT-Technique Description
1Clinic of Reconstructive Dentistry, Center for Dental Medicine, University of Zurich, Zurich, Switzerland.
Summary
The substance-gain extrusion technique (SGET) combined with biologically oriented preparation technique (BOPT) offers a minimally invasive method for restoring severely fractured teeth. This approach preserves natural dentition, improves esthetics, and ensures soft tissue stability, serving as a viable alternative to implants.
Area of Science:
- Restorative Dentistry
- Periodontology
- Prosthodontics
Background:
- Deep subgingival tooth fractures present complex restorative challenges.
- Traditional treatments like orthodontic extrusion or implants can be invasive and costly.
- Minimally invasive alternatives are sought to preserve natural dentition and optimize outcomes.
Purpose of the Study:
- To introduce and describe the substance-gain extrusion technique (SGET) as a novel approach for managing deep subgingival fractures.
- To evaluate the combination of SGET with the biologically oriented preparation technique (BOPT) for predictable restorative solutions.
- To highlight the benefits of SGET in preserving natural teeth and enhancing esthetic and functional results.
Main Methods:
- A case study involving a patient with a failed anterior bridge and medical conditions contraindicating extensive surgery.
- Substance-gain extrusion technique (SGET) using the Benex system for controlled coronal extrusion of a fractured tooth.
- Restoration following BOPT principles, including fiber post placement, composite core buildup, and zirconia crown fabrication.
- Comparison with an immediately placed implant-supported crown on the contralateral incisor.
Main Results:
- Successful preservation of the natural tooth treated with SGET and BOPT.
- Favorable esthetic and functional outcomes at 6-month follow-up.
- Radiographic evidence of stable marginal bone levels and excellent soft tissue integration.
- High patient satisfaction with the restorative outcome.
Conclusions:
- The combination of SGET and BOPT presents a minimally invasive, cost-effective, and time-efficient alternative to implant therapy for significant tooth structure loss.
- This technique shows promise for preserving natural dentition while achieving predictable esthetic results and enhancing soft tissue stability.
- Further long-term clinical data are needed to fully establish the longevity of this approach.

01:20¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)
When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...
01:06Nuclear Overhauser Enhancement (NOE)
Irradiation of a spin-active nucleus causes an increase or decrease in the signal intensity of neighboring nuclei that are not necessarily chemically bonded or involved in J-coupling. This phenomenon, called the nuclear Overhauser enhancement (NOE), results from through-space interactions between the nuclear spins. The NOE effect decreases with increasing internuclear distance and is generally not observed beyond 4 angstroms. In NOE, dipole-dipole interactions between neighboring spin-active...

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...

Insensitive Nuclei Enhanced by Polarization Transfer (INEPT) is an advanced Nuclear Magnetic Resonance (NMR) technique specifically designed to detect and enhance the signals of low-abundance nuclei, such as carbon-13 and nitrogen-15, in small molecules. The fundamental principle behind INEPT is the transfer of polarization from a more abundant and highly polarizable nucleus, typically hydrogen-1, to the low-abundance nucleus of interest. This process effectively boosts the NMR signal of the...
