Quick Answer
A dental trephine is a cylindrical cutting instrument used in selected bone-core, osteotomy, biopsy, harvesting or implant-removal workflows. The stated size alone is not enough for selection. The clinician must confirm internal diameter, external diameter, wall thickness, cutting length, depth markings, handpiece connection, approved speed, irrigation and the planned clinical use.
PearlyGlow Listed Sizes
The current PearlyGlow product records list Dental Trephine Drills in sizes 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm and 10 mm. Before publication, confirm whether each number refers to the internal or external diameter and verify the actual measured dimensions.
Why Internal and External Diameter Matter
A cylindrical trephine has a cutting wall. The bone core or osteotomy dimension can therefore differ from the size printed in a product title. Product pages should provide a labelled diagram showing both dimensions and the cutting-wall thickness.
Selection and Verification Table
Specification | Why it matters | What to publish |
|---|---|---|
Internal diameter | Relates to the potential core diameter | Verified measured value |
External diameter | Relates to the outer osteotomy diameter | Verified measured value |
Cutting length | Limits usable cutting depth | Exact length and markings |
Connection | Must match the approved handpiece/system | Connection type and compatibility |
Speed and irrigation | Affects cutting and thermal management | Only manufacturer-approved parameters |
Sterility/reuse status | Changes reprocessing and use | Exact IFU statement |
Inspection Checklist
The cylindrical cutting edge is continuous and free from chips or deformation.
The instrument is concentric and does not show visible bending.
Depth markings and size identification are readable.
The connection is not worn, damaged or contaminated.
The lumen or internal surface is visibly clean according to the approved method.
The trephine has not exceeded any manufacturer-stated reuse or service limit.
Clinical Evidence and Caution
Clinical studies have used trephine drills in sinus-lift osteotomy, bone-core harvesting, biopsy and implant-removal workflows. These studies demonstrate that trephines have multiple specialised applications, not that any size is suitable for a generic task. Case planning and the exact device instructions remain essential.
Frequently Asked Questions
Does 6 mm mean a 6 mm bone core?
Not necessarily. Confirm whether 6 mm is the internal or external diameter.
Can a trephine be selected only by implant diameter?
No. The planned procedure, surrounding bone and device dimensions must be considered by the clinician.
Are all trephines reusable?
Verify the PearlyGlow instructions and any validated reuse limit.
How should a trephine be cleaned?
Follow the product-specific cleaning method, including any approved brush or flushing instruction.
When should it be replaced?
Remove it when the cutting edge, connection, concentricity, markings or cleanability are compromised.
