What to Know About a Temporary Dental Crown

Understanding Temporary Dental Crowns

This post was written with Consensus AI Academic Search Engine – please read our Disclaimer at the end of this article. Temporary dental crowns are essential components in restorative dentistry, serving as interim solutions while permanent crowns are being fabricated. They play a crucial role in protecting the prepared tooth, maintaining aesthetics, and ensuring proper function. This article explores various aspects of temporary dental crowns, including their fabrication techniques, materials, and clinical performance.

Fabrication Techniques

Temporary crowns can be fabricated using different techniques, each with its own advantages and limitations. Direct chairside methods involve creating the crown directly in the patient’s mouth, which can be convenient but may not offer the best mechanical properties. In contrast, digitally fabricated crowns using CAD/CAM technology have been shown to provide superior mechanical properties, such as better marginal and internal fit, and higher fracture strength compared to direct handmade counterparts1 9.

Materials Used

The choice of material for temporary crowns significantly impacts their performance. Common materials include polymethyl methacrylate (PMMA), bis-acrylic composites, and high-performance polymers like PEKK. Studies have shown that PEKK-made temporary crowns offer a stable and aesthetically pleasing alternative to traditional materials like cobalt chrome, with no significant differences in clinical parameters such as plaque index and probing depth2. Additionally, novel materials like PLA-based resins have demonstrated promising results in terms of structural durability and marginal seal under cyclic loading conditions7.

Clinical Performance

The clinical performance of temporary crowns is evaluated based on several factors, including retention, marginal leakage, and patient satisfaction. Temporary cement cleaning methods can affect the retention of crowns, with air-abrasion techniques improving retention when using zinc phosphate cement4. Marginal microleakage is another critical factor, with zinc-phosphate cements showing reduced leakage compared to other temporary cements5. Patient satisfaction is also a key consideration, with studies indicating that the direct-indirect fabrication technique can enhance aesthetic outcomes and patient experiences3.

Periodontal and Aesthetic Considerations

Temporary crowns play a role in maintaining periodontal health and aesthetics during the interim period. They help in preserving gingival health and can be designed to improve the esthetic appearance of the dental restoration. Techniques such as the use of U-shaped flaps in conjunction with temporary crowns have been shown to enhance soft tissue aesthetics around dental implants6. Moreover, the choice of material and fabrication technique can influence plaque adherence and gingival response, with some materials showing increased plaque accumulation compared to untreated teeth8.

Conclusion

Temporary dental crowns are vital in ensuring the success of permanent restorations. The choice of fabrication technique and material can significantly impact their mechanical properties, clinical performance, and patient satisfaction. Advances in materials and digital fabrication techniques continue to improve the quality and functionality of temporary crowns, making them an indispensable part of modern dental practice.
