In the contemporary landscape of dentistry, certain procedures serve as fundamental pillars of restorative care. Crown and bridge dentistry, a practice aimed at replacing damaged or missing teeth, has long been pivotal in enhancing both oral function and aesthetics. Traditionally, crafting dental crowns and bridges has relied on labor-intensive techniques, often entailing manual molding and casting. However, a transformative wave has swept over this field, ushering in novel possibilities and unprecedented precision through the intersection of crown and bridge techniques with 3D printing and digitalization.
1. UNDERSTANDING DENTAL RESTORATION
Dental restoration stands as a crucial aspect of oral healthcare, with the goal of replacing damaged or missing teeth using prosthetic devices like crowns and bridges.
- Crown Dentistry:
A dental crown, often referred to as a dental cap, is a customized prosthetic covering that encases a damaged, weakened, or aesthetically compromised tooth. Crowns are designed to restore the tooth’s strength, shape, and appearance, providing protection and improving its overall function. They can be made from various materials, including composite, metal alloys, and ceramic compounds, each with its own set of advantages and considerations.
- Bridge Dentistry:
A dental bridge is a prosthetic appliance used to replace one or more missing teeth by bridging the gap between adjacent natural teeth. The bridge consists of one or more artificial teeth, known as pontics, which are anchored to the neighboring teeth or dental implants. Dental bridges serve to restore both aesthetics and function, preventing the shifting of remaining teeth and maintaining proper bite alignment.
2. CHALLENGE OF TRADITIONNAL METHODS
Traditional methods in crown and bridge dentistry have long been effective in restoring appearance, comfort and oral functionality. However, they have not been without their limitations. One of the first limitations are inconsistencies in sizing and fit, which can result in discomfort for patients and compromise the longevity of restorations.
Indeed, traditional methods do not offer the opportunity to verify or correct errors that may arise during the process of taking molds. These errors can include excessive compression, lack of moisture control, incorrect extensions of the borders, excessive pressure on the supporting surfaces, inaccurate dimensional assessment, and improper centering of the impression tray. Additionally, factors such as incorrect material viscosity during insertion into the mouth and excessive material during the loading of the impression tray can contribute to inaccuracies.
Moreover, the conventional impression process involves a series of sequential steps that follow the initial surface impression. These subsequent steps, including casting and model preparation using additional materials like plaster, are susceptible to introducing cumulative errors. These errors can accumulate and lead to larger discrepancies in the final adaptation of the prosthesis or restoration. As a result, the final restorations might require multiple adjustments, leading to prolonged treatment times and increased patient frustration.
The introduction of 3D printing has revolutionized this domain, streamlining procedures and enhancing outcomes.
3. 3D PRINTING AND DIGITALIZATION
The introduction of 3D printing technology into the realm of crown and bridge dentistry, thanks to 3d printed models has brought with it a promising solution to traditional method challenges. 3D printing, also known as additive manufacturing, enables the creation of three-dimensional objects from digital designs by layering material upon the material. This revolutionary approach empowers dental professionals to craft precise and customized restorations with unparalleled accuracy.
Digital Impressions and Intraoral Scanners
Central to the success of 3D printing in dentistry is the shift from traditional molds to digital impressions, with CAD/CAM (Computer-Aided Design and Manufacturing) playing a pivotal role. Intraoral scanners, a cornerstone of digitalization, have become essential tools in this transition. These compact devices also utilize advanced imaging technologies to capture detailed, high-resolution scans of the oral cavity. The discomfort associated with traditional impressions is eliminated, as patients experience a non-invasive and streamlined process.
Moreover, digital impressions provide real-time visualization, enabling both the dental practitioner and the patient to promptly evaluate the scan’s quality, ensuring precision before moving forward. These impressions could serve as a tangible communication tool for patients, helping them grasp and give consent to dental treatments. This tool provides a clear comprehension of their oral health condition, thereby enhancing the patient-practitioner relationship and fostering better treatment decisions. The integration of CAD/CAM technology further empowers dental professionals to seamlessly translate these digital impressions into precise, patient-specific restorations, revolutionizing the field of dentistry.
