• Higher cost compared to conventional materials

VII. Considerations for Material Selection

Choosing the appropriate dental material for implant-supported prostheses involves careful consideration of various factors. Dentists must assess the patient’s specific needs, esthetic requirements, oral health condition, and any existing allergies or sensitivities. Additionally, the location of the implant and the expected functional demands play a crucial role in material selection. Here are some important considerations to keep in mind:

1. Esthetics: The visibility of the implant-supported prosthesis is a significant factor in material selection. For anterior restorations or areas where esthetics are paramount, materials like zirconia or metal-ceramic composites may be preferred due to their natural tooth-like appearance.
2. Strength and Durability: The longevity of the prosthesis is essential for patient satisfaction. Materials like titanium and metal-ceramic composites offer excellent strength and durability, ensuring long-term stability and resistance to wear.
3. Biocompatibility: The biocompatibility of the material is crucial to minimize adverse reactions and promote successful osseointegration. Titanium is known for its superior biocompatibility, making it a widely accepted choice in implant dentistry. However, advancements in ceramic materials, such as zirconia, have also demonstrated excellent biocompatibility.
4. Allergies and Sensitivities: Some patients may have allergies or sensitivities to certain metals. In such cases, a metal-free option like zirconia or polymer materials may be more suitable to prevent allergic reactions and ensure patient comfort.
5. Long-Term Clinical Data: It is important to consider the availability of long-term clinical data regarding the performance and success rates of different dental materials. Materials with extensive clinical track records provide reassurance and help predict the long-term outcome of the restoration.
6. Cost Considerations: The cost of materials is a significant factor to consider, as it may vary depending on the type and quality of the material. While certain materials, such as zirconia, may have higher initial costs, they may provide superior esthetics and longevity, leading to cost savings over time.
7. Treatment Complexity: Some materials, like hybrid options combining titanium and zirconia, may require more complex treatment planning and execution. Dentists should assess their expertise and the feasibility of using these materials based on the specific case requirements.

VIII. Advances in Dental Material Science
