Metal Restorations
PFM (Porcelain Fused to Metal) crown stands as a proven restoration known for its strength and durability. When dealing with challenging and intricate cases that demand precision attachments or require substantial strength in limited spaces, PFM crowns may be the most suitable choice. In difficult and complex situations that require precision attachments or high strength in limited spaces, PFM crowns may be the most suitable choice. These crowns closely resemble natural teeth as they consist of a metal base layered with porcelain, ensuring a natural and lifelike appearance. From single units to roundhouse bridges, porcelain fused to metal has the versatility for the job.
Classification System
The three main categories under which the fabrication of dental crowns generally falls are: high noble (precious), noble (semi-precious), and non-noble (non-precious).
As the names suggest, this classification system draws its essence from the very composition of the alloys. Each of these dental alloys is defined by its own set of physical characteristics, with comparative advantages and disadvantages that allow an intricate array of possibilities.
We understand that every dental masterpiece is a symphony of artistry, science, and patient aspirations. With meticulous precision and artistic finesse, Yen Dental Laboratory strives to elevate dental restoration to an exquisite level, leaving no room for compromise.
The Ultimate Pursuit
Where dental artistry is concerned, no two situations are alike. Each demands a nuanced clinical decision regarding replacement, repair, or careful observation.
At Yen Dental Laboratory, we understand that the ultimate pursuit is the desired outcome. By meticulously delineating the specific objectives, we pave the way for choosing the most suitable material, while cultivating an unwavering commitment to an outcome-based mindset.
Our dedicated team of technicians use their skills in the blending of today’s materials to create highly aesthetic, yet functional restorations.
PFM Crowns – High Precious Alloy
If cost is not a factor, opting for an alloy with the highest precious metal content is usually the superior choice.
So, what exactly is a precious metal crown? These remarkable dental crowns consist of two essential components. The inner core is meticulously crafted using a variety of precious metals or alloys, such as gold, platinum, or palladium. This inner core is then encased with layers of porcelain, creating an aesthetically pleasing appearance that seamlessly blends with natural teeth.
Unsurprisingly, precious metal restorations have gained tremendous popularity worldwide, and for good reason. They are commonly prescribed for single unit crowns, bridgework, inlays, and onlays. With proper care and usage, they can last for many years, ensuring long-term dental health and happiness.
Core Strength, Aesthetic Appearance
Composed of precious metal, the inner core provides exceptional durability, allowing it to withstand the rigours of daily chewing while safeguarding the teeth from external forces.
Moreover, these crowns seamlessly integrate with the gum and bone structure, offering optimal compatibility and resistance to oxidation within the oral environment, under the watchful influence of saliva.
Precious Craftsmanship
At Yen Dental Laboratory, we understand the significance of selecting the perfect alloy for PFM crowns. Our commitment to excellence drives us to utilise high precious alloys in crafting crowns that surpass expectations.
With our expertise and dedication to precision, we ensure that our PFM crowns with high precious alloy will bestow unparalleled beauty, strength, and resilience to your smile.
Natural & Biocompatible Properties
But that’s not all. Precious metal crowns are known for their remarkable biocompatibility, making them an ideal choice for patients with allergies or sensitivities. The natural coloration of these crowns ensures a harmonious blend with the surrounding teeth, minimising any discernible differences. Their low reflectivity prevents unsightly glares, effectively reducing the risk of discolouration.
It’s worth noting that gold, a primary component of precious metal crowns, possesses impressive antibacterial properties. As a result, these crowns exhibit anti-inflammatory abilities, offering additional oral health benefits to the wearer.
Comprising over 95% noble metals, with yellow gold constituting more than 85% of the composition, these alloys stand tall. The prestigious noble metals include gold, palladium, and platinum each contributing to the exceptional quality and longevity of high noble alloy crowns.
PFM Crowns – Semi-Precious Alloys
Semi-precious alloys offer a multitude of benefits, making them an attractive choice for dental restorations. One key aspect that distinguishes these crowns is the composition of the alloys used, which includes a minimum of 65% noble metal content, with over 50% consisting of yellow gold.
Their inherent strength and durability ensure reliable performance, while the good marginal integrity contributes to long-lasting restorations.
With proper oral hygiene practices, PFM crowns featuring semi-precious alloys can endure for many years, providing patients with lasting satisfaction. At Yen Dental Laboratory, these alloys have been meticulously tested and certified, guaranteeing their efficacy and reliability.
Indications & Contraindications
Indications for PFM crowns with semi-precious alloys encompass a broad range of applications. They can be utilised for anterior/posterior crowns, bridges spanning various gaps, implant crowns, as well as crowns situated under partial dentures.
However, it is important to note certain contraindications. PFM crowns with semi-precious alloys may not be recommended for restorations requiring a close match to highly translucent teeth or adjacent all-ceramic crowns. Additionally, patients with specific sensitivities to these alloys may need alternative options.
Tried and Tested Approach
To ensure the optimal fit and function of PFM crowns with semi-precious alloys, proper preparation is essential. The recommended reduction dimensions are as follows: 2mm for incisal/occlusal reduction, 1.5mm for facial/lingual reduction, and 1.2mm for cervical reduction. Adhering to these guidelines aids in achieving desirable outcomes and patient satisfaction.
When it comes to cementation, a conventional (standard) cementation procedure and materials are typically employed. This tried and tested approach ensures reliable bonding and enhances the longevity of the restorations.
PFM crowns that feature semi-precious alloys combine strength, versatility, and the proven reliability of certified noble dental alloys. With their decades-spanning track record, PFM crowns with semi-precious alloys continue to be a viable and trusted option for dental professionals and patients alike.
PFM Crowns – Non-Precious Alloys
At Yen Dental Laboratory, we use nickel-free base metal or non-precious alloys. These alloys consist of metals such as Cobalt (Co), Chromium (Cr), Molybdenum (Mo), Silicon (Si), Manganese (Mn). The alloy composition ensures the desired attributes of strength, durability, and biocompatibility while completely removing nickel, making it an optimal choice for individuals with nickel allergies or sensitivities. Additionally, non-precious alloys are abundantly available in nature, making them the most economical alternative for tooth-colored metal restorations.
The Right Rigidity
Despite these challenges, base metal alloys offer advantages such as enhanced hardness and strength compared to noble metals. They exhibit twice the elasticity, enabling the creation of thinner crowns while still maintaining the necessary rigidity for dental applications.
Broad & Versatile Applications
The indications for PFM Non-Precious Nickel-Free restorations are broad and versatile. They can be used for various applications including single unit crowns, short-span and long-span bridges, implants, crowns with attachments, and crowns fitted to partials. This wide range of indications allows dental professionals to address diverse patient needs effectively.
Firm Bond
When it comes to cementation, several options are available. Glass ionomer cement such as GC Fuji and GC American, Panavia 21 (which must be tinplated), polycarboxylate cement, resin ionomer cement like RelyX from 3M ESPE, and zinc phosphate cement can all be utilised for secure and reliable bonding.
Yen Dental Laboratory understands the importance of versatility, functionality, and affordability in dental restorations. PFM Non-Precious Nickel-Free restorations exemplify these qualities, providing excellent aesthetics, a wide range of indications, and cost-effectiveness. Dental professionals can rely on these restorations to deliver exceptional results and patient satisfaction.
Full Cast Metal
Full-cast metal restorations offer a robust solution with exceptional durability. They are particularly suitable for patients with severely damaged posterior teeth.
The biocompatibility of full-metal crowns, especially when noble or precious metal alloys are utilised, is noteworthy. Metal alloys, such as gold crowns, exhibit excellent compatibility with gingival tissue, minimising the likelihood of allergic reactions. Additionally, they are resistant to plaque accumulation, corrosion, and fluid absorption.
At our facility, we manufacture full-cast crowns using a diverse range of materials. These include high precious yellow gold (with a minimum yellow gold content of 75%), semi-precious (with a minimum yellow gold content of 50%), mini gold (with a minimum yellow gold content of 20%), and full-cast non-precious cobalt chrome (silver colour). Our crowns are meticulously designed to provide exceptional durability while minimising the necessity for tooth reduction. Additionally, they offer outstanding biocompatibility and a low risk of fracture, ensuring optimal performance and utmost patient satisfaction.
Extraordinary Tensile Strength
The high tensile strength of full-cast metal crowns allows for thin restorations, preserving more of the patient’s original tooth structure. This advantage, made possible by the strength of modern dental alloys, sets them apart from PFM or all-ceramic crowns. When space is limited, a full-cast crown becomes an attractive option.
Not only do full-cast metal crowns exhibit remarkable strength, they are also gentle on opposing dentition, reducing the risk of excessive wear due to their similar coefficient to tooth enamel. If concerns arise regarding wear on opposing teeth, selecting high-precious or semi-precious dental alloys is typically recommended. These alloys are softer yet highly durable, ensuring a harmonious balance. Furthermore, their coefficient of expansion closely matches that of natural teeth.
