Top 5 questions and answers to an orthopedic dentist about prosthetics on implants
Fixed implant-supported prosthetics is one of the most reliable and aesthetic ways to restore the dentition. Despite the high demand for this technology, patients often have similar questions regarding durability, osseointegration, contraindications, and the specifics of the procedure. Below are answers to the five most popular queries to help you better understand the process and make an informed decision.
1. What is the lifespan of implant-supported crowns?
Crowns installed on implants last an average of 6–8 years, but with proper care, this period can reach 10-12 years or more. Durability is influenced by the quality of materials, the doctor's professionalism, the state of the bite, and oral hygiene. Metal-ceramics and zirconium dioxide show the best results in terms of wear resistance. It is important to understand that if a crown needs replacement, the implant itself usually continues to serve without replacement.
2. How well do implants integrate?
Modern dental implants have a high success rate of osseointegration – from 97% to 99%. Provided there are no serious contraindications and the doctor's recommendations are followed, the risk of rejection is minimal. The process of osseointegration (the merging of the implant with the bone) takes from 3 to 6 months, depending on the condition of the patient's bone tissue and body.
3. What are the contraindications for installing implant-supported crowns?
Despite the broad possibilities of the technology, there are absolute and relative contraindications. Absolute ones include: active oncological diseases, severe blood diseases, uncontrolled diabetes mellitus, and immunodeficiency states. Relative ones include pregnancy, age under 18, and acute inflammatory processes in the oral cavity. Before starting dental prosthetics, a thorough diagnosis is performed to exclude risks.
4. Which is better: screw or cement fixation of crowns?
Screw fixation is considered more preferable as it provides easy access to the structure for possible maintenance or replacement without damaging the crown. Cement fixation is used less frequently, mainly for aesthetic reasons, when it is necessary to completely hide the fastening elements. The choice of method depends on the clinical situation, the patient's wishes, and the orthopedic surgeon's recommendations.
5. How long does the entire process of fixed implant-supported prosthetics take?
The total duration depends on the initial state of the dentofacial system. If the implant installation is performed in one stage with immediate loading, the crown can be received within a few hours or 1-2 days. In the classic version, the process takes from 3 to 6 months, including the time for implant osseointegration and the fabrication of permanent structures. If bone grafting is required, the timeframe may increase.
Fixed implant-supported prosthetics is a modern solution that combines functionality, aesthetics, and durability.
Knowing the key aspects of the procedure helps the patient make informed decisions and reduces anxiety before treatment. Regular preventive visits and consultations, proper hygiene, and choosing a qualified specialist are the keys to a long implant life and daily comfort.
