Replacing a short abutment screw in Hiossen implants is a critical procedure in implant dentistry, often required when the original screw is damaged, fractured, or loose. This comprehensive guide will walk you through the process step-by-step, including preparation, removal of the damaged screw, and installation of a new short abutment screw. Additionally, we will discuss the tools and kits designed specifically for Hiossen implants, troubleshooting tips, and best practices to ensure a successful replacement.
Hiossen implants use abutment screws to secure the abutment to the implant fixture. The short abutment screw Hiossen variant is designed for specific clinical situations where limited vertical space or other anatomical factors require a shorter screw length. These screws play a crucial role in maintaining the stability and integrity of the implant-supported restoration.
- Designed to fit implants with limited intermaxillary space.
- Compatible with various Hiossen implant systems (EK, ET, SS).
- Require precise torque application to avoid loosening or fracture.
- Available in different diameters and lengths to suit implant size and clinical needs.
Understanding the design and function of the short abutment screw Hiossen helps clinicians appreciate why proper handling is essential. The reduced length of the screw means less engagement with the implant threads, making accurate torque and careful handling even more important to avoid complications such as screw loosening or fracture.
Replacing a short abutment screw often requires specialized instruments to safely remove the damaged screw and install a new one without damaging the implant threads.
The ESR Kit is specifically designed for removing fractured or damaged abutment screws, including short abutment screws in Hiossen implants. It includes:
- Abutment Removal (AR) Tips: For engaging and extracting fractured screws.
- Reverse Drills and Screw Removal Tips: To create access and back out damaged screws.
- Re-Tap Tools: To restore damaged internal threads after screw removal.
- Torque Wrenches and Handles: For precise control during removal and reinstallation.
This kit is essential for clinicians dealing with complex screw removal cases. Its design allows for minimally invasive procedures that preserve the implant and surrounding bone.
- Hex drivers (1.2 mm) for tightening and loosening screws.
- Forceps to assist in gripping and removing the abutment or screw.
- Round burs (Ø0.8 mm) to create pilot holes in damaged screws for removal tools.
- Irrigation and air blast devices to clear metal debris during removal.
Using the right instruments reduces the risk of further damage and improves the success rate of screw replacement procedures.
Before starting the procedure, conduct a thorough clinical and radiographic evaluation to assess the condition of the implant, abutment, and screw. Confirm that the screw in question is a short abutment screw Hiossen and determine its size and type to select the correct replacement.
Prepare the surgical field with proper aseptic techniques. Ensure all necessary instruments, including the ESR Kit and hex drivers, are sterilized and ready.
a. Using the Abutment Removal (AR) Tip
- Insert the AR tip into the abutment screw hole.
- Rotate the AR tip counterclockwise to engage the screw.
- Use forceps to grasp the AR tip and gently wiggle the screw left and right to loosen it.
- Carefully pull the screw out once loosened.
b. Creating a Hole for Difficult Screws
If the screw head is stripped or fractured, making standard removal impossible, create a hole in the screw hex using a Ø0.8 mm round bur. This provides a grip point for the AR tip.
- Attach the mini AR tip into this hole.
- Rotate counterclockwise to remove the screw.
c. Using Reverse Drill and Screw Holder
- Attach the guide to the implant and connect the ESR handle.
- Insert the reverse drill into the guide and rotate counterclockwise at 1,200–1,500 rpm with irrigation.
- Once the screw is loosened, use the screw holder to back it out completely.
This method is particularly useful when the screw is fractured below the head or when the screw is tightly lodged.
After screw removal, thoroughly irrigate the implant to remove metal debris, which can cause inflammation or peri-implantitis if left inside.
Inspect the internal threads for damage. Damaged threads can compromise the stability of the new screw and the entire implant restoration.
If threads are damaged, use the re-tap tool with a torque wrench to restore them by gently rotating clockwise with 30 Ncm torque. Repeat until the threads are clean and intact.
Select the appropriate short abutment screw Hiossen matching the implant system and clinical requirements.
- Hand-tighten initially using a 1.2 hex driver.
- Apply the recommended torque (usually specified by Hiossen, e.g., 30 Ncm) with a calibrated torque wrench.
- Ensure the abutment is securely attached without over-tightening to prevent future screw loosening or fracture.
Proper torque application is critical because overtightening can cause screw fracture, while undertightening can lead to loosening.
Reinstall the prosthetic crown or restoration carefully. Verify occlusion and implant stability to ensure that the replacement screw and abutment are functioning correctly.
Schedule follow-up visits to monitor screw integrity and implant health. Early detection of any screw loosening or complications will allow timely intervention.
Replacing a short abutment screw Hiossen can present challenges. Here are common issues and how to address them:
- Stripped Screw Head: Use a round bur to create a slot or hole for AR tip engagement. Avoid excessive drilling to prevent damage to the implant.
- Fractured Screw Shaft: Employ ESR Kit tools for careful extraction; if unsuccessful, consider a custom driver or drilling out the screw.
- Damaged Implant Threads: Use re-tap drills to restore threads before placing a new screw. If damage is severe, consult with implant manufacturer or consider implant replacement.
- Excessive Torque Needed: Avoid forcing; reassess screw engagement and consider alternative removal techniques.
- Metal Debris Management: Always irrigate and air-blast to clear debris to prevent peri-implantitis.
Proper troubleshooting ensures the longevity of the implant restoration and patient satisfaction.
- Use a calibrated torque wrench to apply the correct torque during screw installation.
- Avoid overtightening to prevent screw fracture.
- Regularly check screw tightness during follow-up appointments.
- Educate patients on avoiding excessive occlusal forces that may loosen screws.
- Use quality prosthetic components compatible with Hiossen implant systems.
Adhering to these practices minimizes the need for screw replacement and enhances implant longevity.
Replacing a short abutment screw in Hiossen implants requires precision, patience, and the right tools. The use of specialized kits like the ESR Kit facilitates safe and efficient removal of damaged screws while preserving the implant integrity. Following a systematic approach-from assessment, removal, cleaning, to reinstallation-ensures long-term success of the implant restoration. Proper torque application and regular follow-up are essential to prevent recurrence of screw-related complications. With the right technique and equipment, clinicians can confidently manage short abutment screw replacements in Hiossen implants, ensuring optimal patient outcomes and implant longevity.
A short abutment screw in Hiossen implants is a screw designed with reduced length to fit clinical situations with limited vertical space, ensuring secure attachment of the abutment to the implant fixture.
Signs include loosening of the prosthesis, difficulty in tightening the screw, visible damage to the screw head, or radiographic evidence of screw fracture.
Yes, the ESR Kit is compatible with various Hiossen implant systems, including EK, ET, and SS, and includes tools for different screw sizes and types.
Use the re-tap tool included in the ESR Kit to carefully restore the internal threads before placing a new abutment screw.
Typically, a torque of around 30 Ncm is recommended, but always follow Hiossen's specific guidelines for the implant system used.
