This article investigates the different elements that determine the effectiveness of dental implants, emphasizing that age should not be the primary concern when deciding on dental repair.
Understanding Dental Implants
Dental implants are artificial tooth roots that are surgically placed into the jawbone. They act as a solid basis for replacement teeth, providing a long-term and natural-looking alternative to missing teeth. The procedure involves several steps, including the placement of the implant, healing time for osseointegration (the process of the implant fusing with the bone), and the final restoration with a crown or bridge.
Key Factors Influencing Dental Implant Success
While age can play a role in the decision to pursue dental implants, several other key factors are critical in determining whether an individual is a suitable candidate for the procedure.
1. Bone Health and Density
Importance of Bone Density
The health and density of the jawbone are critical to the success of dental implants. A substantial amount of bone is required to fix the implant securely.  If a patient has experienced bone loss due to prolonged tooth loss or other factors, additional procedures, such as bone grafting, may be required to enhance bone volume before implant placement.
Assessing Bone Health
Dental professionals utilize imaging techniques, such as X-rays or Cone Beam CT (CBCT) scans, to evaluate the condition of the jawbone. This assessment helps determine if the existing bone structure can support the implant or if preparatory treatments are necessary.
2. Overall Oral Health
Gum Health
Healthy gums are essential for the success of dental implants. Conditions like gum disease (periodontitis) can compromise the stability of the implant and lead to failure. Prior to the implant procedure, any existing oral health issues must be addressed to ensure a healthy environment for the implant.

Patients must exhibit a dedication to good oral hygiene, which includes frequent brushing, flossing, and dental check-ups. Good oral care is crucial for the longevity of dental implants and the prevention of complications.
3. General Health and Medical History
Impact of Chronic Conditions
A patient's overall health plays a significant role in determining candidacy for dental implants. Chronic conditions such as diabetes, heart disease, and autoimmune disorders can affect healing and increase the risk of complications. While these conditions do not automatically disqualify a patient from receiving implants, they require careful management and evaluation by a healthcare provider.
Medications and Healing
Certain medications can also impact the healing process and osseointegration of dental implants. To build a safe and effective treatment plan, patients must supply their dental provider with their complete medical history as well as any drugs they are currently taking.
4. Psychological Readiness
Beyond physical health, psychological readiness is a crucial factor in the decision to undergo dental implant surgery. Patients must be mentally prepared for the procedure and committed to following post-operative care instructions. This commitment is vital for achieving a positive outcome.
Age Considerations in Dental Implant Candidacy
While age is often perceived as a limiting factor for dental implants, it is essential to recognize that it is not the sole determinant of eligibility.
Young Adults (Late Teens to Early Twenties)
Young adults may consider dental implants after the jawbone has fully matured, typically around the ages of 18 to 21. This age group frequently benefits from faster healing times and may consider implants for causes such as congenital defects or accidents.
Middle-Aged Adults (Late Twenties to Fifties)
For individuals in their middle years, the decision to opt for dental implants is often driven by lifestyle factors, including the desire for a permanent and aesthetically pleasing solution. This age group generally has optimal bone health and overall well-being, making them ideal candidates for implants.
Seniors (Sixties and Beyond)
Contrary to common belief, seniors can also successfully undergo dental implant procedures. Advances in dental technology, such as immediate load implants or bone augmentation techniques and rigorous pre-assessment enable older people to reap the benefits of dental implants, provided they meet the essential health requirements.  Age alone should not deter seniors from exploring this restorative option.
Conclusion
Choosing the right dental implants involves considering various factors beyond age. While age can influence candidacy, it is not the sole determinant. Understanding these factors empowers patients to make informed decisions about their dental health and explore the transformative potential of dental implants.

A: Hardness is a measure of a material's ability to withstand impacting and abrasive forces, yet it also occupies a unique mechanical intersection between toughness and strength. Zirconia are extremely tough with outstanding impact resistance qualities. This denotes a balance between hardness, toughness, and strength which enables zirconia ceramics to withstand extremely high amounts of friction.

A: Aconia® blanks are made by CIP( Cold Isostatic Pressing) processing technology. Cold isostatic pressing is the most accepted procedural technique for shaping Y-TZP and produces stable, chalk-like non-sintered green-stage objects with a very high primary density. Aconia® blanks have the proper density. High-density blanks are easily damaging the burs during the milling. Insufficient density blanks will cause margin chipping in a higher percentage.

A: Fracture toughness is used to describe an ability of a material with a crack in it to resist further fracture. The higher fracture toughness of zirconia, the lower probability of the crack spreading in restorations. So the high value of fracture toughness ensures superior clinical long-term performance, which means the restorations can be long-term lasting. That is why fracture toughness is a clinically significant value. Aconia® HT plus has fracture toughness more than 9 MPa · m1/2. This highlight has helped more and more technicians to achieve more success in their work.

For the dental zirconia, high flexural strength means wider indications, so it can be used to make restorations with more units. On the other hand, high flexural strength also affects the thickness of the restoration walls. A high-strength material allows a low wall thickness. Aconia® provides a wide range of zirconia blanks with different flexural strength, which means you can select the best solution for balancing aesthetics and strength.

Flexural strength is a term that is frequently used in dental zirconia products, and it has been considered as a key feature of the stability of the material. In general, flexural strength indicates the resistance of a material against deformation. The commonly used flexural strength testing method is a 3-point testing method & 4-point testing method. The values measured from different testing method are not comparable. All Aconia® zirconia applies with the 3-point testing method.

Crystal phases are used to describe the crystalline structure of substance under different temperatures. ZrO2 has three crystal phases: monoclinic, tetragonal and cubic. The monoclinic phase is stable at room temperatures up to 1170 ℃, the tetragonal at temperatures of 1170-2370 ℃ and the cubic at over 2370 ℃. About Aconia® zirconia, after sintered, the zirconia is mainly combined with tetragonal and cubic phases. The different percentage of crystal structures determines the different properties of sintered zirconia.

Yttria-stabilized zirconia (YSZ) is a zirconium oxide based ceramic, in which the particular crystal structure of zirconium oxide is made stable at room temperature by addition of yttrium oxide. The addition of yttria (Y2O3) as a stabilizing agent in zirconia allows the zirconia can be stable at room temperature with the tetragonal phase or the cubic phase. The different yttria (Y2O3) percentage in zirconia will lead to different ratio of tetragonal form and cubic forms in the final restoration, which come with the different strength and translucency of zirconia restorations. (eg. 3YSZ-with 3 mol-% Y2O3 partially Stabilized ZrO2, Yttria Stabilized Zirconia). Aconia® blanks are Yttria-stabilized zirconia.
