Dental Implant Long Trephine Kit 6pcs Bone Trimming Burs Set Surgical Implant CE
The MediTek Long Trephine Kit is a set of hollow trephine burs for failed implant removal, bone trimming, and tissue punching. It gives implant surgeons and oral surgeons a controlled way to retrieve a fractured, loose, or badly placed implant. If your practice places implants with a dental implant kit, this set covers the other side of the job: safe retrieval.
Why Use a Long Trephine Kit for Implant Removal
A trephine bur is a hollow cutter. You place it over the implant so the implant sits inside the bur, then cut a ring of bone around it. Once the ring is free, an elevator or forceps can loosen the implant. This removes less bone than drilling directly beside the fixture.
The long design helps you reach deeper implants. The range of sizes lets you match the bur to the implant body. Reverse torque devices are the least invasive option. Clinical reviews advise combining them with trephine drills when 4 mm or more of the implant is still integrated, or when removal torque is very high.
What Is Included in the Dental Trephine Burs Set
- Long trephine burs in sizes 3.0 mm, 4.0 mm, 5.0 mm, 6.0 mm, 7.0 mm, 8.0 mm, 9.0 mm, and 10 mm
- Bur holder for organized storage
The size range covers narrow and wide implants, so one trephine kit can handle many removal cases. It also works well next to the dental implant kits you already use for placement.
Key Features
- Medical-grade stainless steel that resists corrosion
- High-polish finish that is easy to clean and inspect
- Precision-engineered cutting edges for controlled bone trimming
- Long burs that reach deeper implant sites
- CE marking and a guarantee against defects in material and workmanship
- Bur holder that keeps every size within reach
Clinical Uses
Failed Implant Removal
Use the bur to free implants that are fractured, mobile, or badly positioned, including cases where a prosthetic restoration is no longer possible.
Bone Trimming
The same burs support bone trimming and contouring, and the removal of small bone segments during oral surgery.
Tissue Punching
The kit is also listed for tissue punching, where you need a clean, round cut.
How to Choose the Right Trephine Bur Size
Check the implant diameter and depth on an X-ray first. Pick a bur with an inner diameter just wider than the implant body, so the implant fits inside without touching the wall. A bur that is too small will not slide over the implant. A bur that is far too large takes extra bone.
Published case work suggests a trephine bur works best when the cortical bone around the implant is thicker than 1.5 mm. It is not the right choice for tissue-level implants with a flared neck.
Safe Use Tips for Trephine Burs
- Work at low speed, since published guidance names a maximum of 800 RPM
- Use plenty of sterile saline to limit heat in the bone
- Apply light, steady pressure and lift the bur often to clear debris
- Confirm depth and position by X-ray to protect nearby teeth and nerves
- Replace any bur that feels dull, because dull burs build heat
Always follow the guidance of your handpiece and implant system manufacturer.
Care and Sterilization
Rinse bone debris off the burs right after use. Clean them, then sterilize with your usual protocol. The polished stainless steel is easy to wipe and inspect. Dry the burs fully and store them in the holder.

Frequently Asked Questions
What is a long trephine kit used for?
It is used to remove failed or fractured dental implants, trim bone, and punch tissue. The hollow bur cuts a ring of bone around the implant so it can be lifted out with minimal damage.
What speed should I use with dental trephine burs?
Published clinical guidance recommends low speed, up to 800 RPM, with copious sterile saline irrigation. This limits heat that can harm the bone. Follow your handpiece manufacturer’s instructions.
How do I choose the right size from a trephine bur kit?
Match the inner diameter of the bur to the implant body. It should be slightly wider than the implant so the implant fits inside. Confirm the implant diameter and depth on an X-ray before you start.
Can a trephine bur remove every implant?
No. Reverse torque is usually tried first, and trephines suit cases with 4 mm or more of integrated bone or high removal torque. They are not suited to tissue-level implants with a flared neck.
How is a trephine kit different from a standard implant drill kit?
A drill kit, such as a dental implant surgical kit, prepares the bone for a new implant. A trephine kit cuts around an existing implant or removes a bone segment. Many practices keep both.
Are these bone trimming burs stainless steel and CE marked?
Yes. They are made from medical-grade stainless steel with a high-polish finish, and the kit is CE marked. The finish makes cleaning and sterilization easier.
