Nobel Biocare’s Jonathan Fleet says “Dental implants – material matters

The achievement of natural-looking esthetics is important in dentistry right now. Enhanced societal pressures have inspired higher patient expectations, but it’s important not to compromise function or longevity of treatment outcomes.

The properties of dental materials used should be considered. Materials can significantly affect factors including the lifespan of the implant and the ease with which esthetic patient expectations can be met – these are often the primary concern of the patient.

Titanium

Due to its physiological inertia, biocompatibility, non-corrosive properties and combination of strength and lightness, titanium is a diverse and utile material that offers many benefits. Titanium implants are stronger than alternatives and other implant materials such as zirconia and dental ceramic are prone to failures in form and chipping [1], resulting in a much longer lifespan.

New grades of the metal have been explored including nanostructured titanium. One study claims that, compared to traditional dental titanium, nanostructured titanium integrates with bone at a quicker rate and is stronger and less prone to diseases such as peri-implantitis [2]. This, in turn, better allows the dental professional to employ immediate placement protocols in the appropriate situations.

Dental porcelain

Natural looking esthetics has ensured dental porcelain is the most widely used material in dental restoration procedures [3]. As well as offering preferred esthetics, research has found the material is a suitable option for implant procedures due to its inert, non-corrosive and hypoallergenic properties [4].

However, research into dental porcelain continues and in recent years the chemical structure of dental porcelain has changed significantly. By creating porcelains with different microstructures and glass compositions, advancements have been made in their durability, opening more possibilities for application [5].

Zirconia

Zirconia deserves to be singled out due to its unique properties. Extremely durable and natural looking, zirconia is also biocompatible and has a translucency that is like that of natural teeth [6], making it a popular option for anterior implants.

Zirconia has high durability and offers stability and mechanical strength similar to that of stainless steel alloys [7]. It’s been found to help the preservation of bone and sometimes result in better gingival health post-implant surgery, reducing the risk of implant failure [8].

Put the patient first

Every patient is unique and it’s important to evaluate which implants will suit their needs most. A specialist in the field with decades of experience and research behind its products, Nobel Biocare provides a wide variety of implants trusted to provide excellent results in a wide range of cases. The NobelActive® range of implants offers the perfect blend of high primary stability and esthetic excellence, making it the optimal choice for patients and practitioners alike.

Keeping up to date with the latest innovations in implantology is the key to offering the best options for patients. Solutions today ensure no compromise between esthetics, functionality or longevity.
