Why we need new implants for 3D printing Resin Ceramics
Current Dental implant mechanical failures
Screw Loosening or Fracture: This is a common issue where the screw that connects the abutment to the implant becomes loose or breaks. Causes can include improper fitting, excessive biting forces, or wear over time.
Abutment Fracture: The abutment, which connects the implant to the prosthetic tooth, can fracture. This might occur due to excessive occlusal forces, material fatigue, or improper implant placement.
Implant Fracture: This is less common but more serious. Fractures in the implant body can occur due to extreme stress, inadequate bone support, or material fatigue. This usually requires surgical intervention.
Bone Loss Around Implant: While not a direct mechanical failure of the implant components, bone loss can lead to implant instability and failure. This could be due to infection, improper loading, or poor bone quality.
Prosthetic Complications: Issues with the crown or prosthetic tooth, such as chipping or loosening, can also be considered a type of mechanical failure.
Why Rodin Implant Interface
We need to prove
Rodin implants has the following advantages over Traditional implants
Mechanical Stability: The Rodin implant connection is designed to ensure a tight, stable fit between the implant and the abutment. This stability is crucial for the long-term success of the implant and helps to distribute the forces exerted during chewing more evenly.
Reduced Micro-Movement: A well-engineered connection interface can minimize micro-movements between the implant and the abutment. This is important in preventing complications such as screw loosening or wear over time.
Improved Sealing Ability: A precise connection interface can enhance the seal between the implant and the abutment, potentially reducing the risk of bacterial ingress and subsequent peri-implantitis (inflammation around the implant).
Biocompatibility: The materials used in the connection interface are typically biocompatible, which is essential for preventing adverse reactions and promoting osseointegration (the process by which the implant fuses with the jawbone).
Aesthetic Outcomes: The connection interface can be designed to support aesthetic outcomes, especially in the anterior (front) region of the mouth, by allowing for a natural-looking emergence profile of the restoration.
Ease of Restoration for Digital Workflow: A user-friendly connection interface simplifies the restorative process for the dentist, making it easier to achieve precise and predictable results.
Problems Related to Overdenture Attachment
Overdentures are a type of removable dental prosthesis that are supported by either natural teeth or dental implants. They are designed to provide a more stable and comfortable solution for individuals with few or no teeth. Despite their advantages, there can be several problems related to overdenture attachments that patients and dental professionals might encounter:
Attachment Wear and Tear: The mechanical components of overdenture attachments can wear out over time due to the constant friction and forces during chewing and speaking. This can lead to a decrease in retention and stability of the overdenture.
Maintenance Issues: Overdentures require regular maintenance to ensure their longevity and comfort. Patients might face challenges in maintaining their overdentures due to difficulties in cleaning or improper handling, leading to issues such as bad odor or infection.
Implant Failures: For implant-supported overdentures, there is a risk of implant failure. This can occur due to poor osseointegration, peri-implantitis (inflammation of the tissue around the implant), or overloading of the implant.
Soft Tissue Irritation: Overdentures can sometimes cause irritation to the soft tissues of the mouth, including the gums. This can be due to ill-fitting dentures, poor oral hygiene, or allergic reactions to the materials used in the overdenture or attachment system.
Loss of Retention: Over time, the retention of an overdenture may decrease due to changes in the jawbone, wear of the attachments, or loosening of the implants. This can result in the overdenture becoming loose and uncomfortable for the patient.
Difficulty in Achieving Proper Occlusion: Achieving the right bite or occlusion can be challenging with overdentures, especially if there are changes in the patient's oral anatomy over time. Incorrect occlusion can lead to discomfort, difficulty in eating, and even damage to the overdenture or remaining natural teeth.
Financial and Economic Concerns: The cost of overdentures, especially implant-supported ones, can be significant. The financial burden can be exacerbated by the need for regular maintenance, repairs, or replacements due to attachment problems.
Addressing these problems often requires a multidisciplinary approach, involving regular dental check-ups, proper patient education on maintenance, and timely interventions to repair or replace worn or damaged components. Advances in dental materials and techniques continue to improve the reliability and comfort of overdenture attachments, helping to mitigate some of these challenges.
