What a massive breakthrough Nobel Biocare has achieved in the field of dental implants to revolutionize Implantology, which enables a fixed and definitive prosthesis to be placed on the same procedural day of placing implants.
Introduced by Dr. Kenji W. Higuchi at the Nobel Biocare Global Symposium 2016, New York, The Trefoil System – includes placing 3 implants in a particular location so that a pre-fabricated titanium bar wrapped in acrylic teeth can be placed on the same day of the implant surgery.
Trefoil system places the implants in the lower (mandibular) arch only. It has proven to be the most affordable fixed, definitive, full-arch tooth replacement option for the lower jaw available today.
PROCEDURAL TIMINGS –
Surgery – 2-3 HOURS
Restorative work – 1 to 2 hours
Laboratory work – 6-7 hours
TECHNIQUE OF PLACING TREFOIL IMPLANTS
Branemark’s guided surgery protocol is to be followed for placement of Trefoil implants in which surgical guides are used to prepare sites and then to guide the positioning of three specially designed implants into predetermined positions in the anterior mandible along with proper radiographic planning.
First, the titanium bar is placed on the jaw affixed with three specialized dental screws, after the laboratory work, the prosthesis is attached.
The concept behind the trefoil system is that the joint attachment system allows us to connect the framework of prosthesis to the dental implants without sacrificing structural integrity or precision during the bar and prosthesis placement procedure.
ADVANTAGES OF TREFOIL
- Shorter treatment time
- Lower treatment cost
- Few prosthetic and laboratory stages
- It provides definitive teeth in a single day
ARE 3 DENTAL IMPLANTS SUFFICIENT FOR ESTABLISHING STABILITY OF PROSTHESIS
Palo Malo once said, that the size of implant is more important than the number of the implant. Trefoil system uses a 5 mm implant instead of 4.4 for all on 4.
CAN ANYONE OPT FOR TREFOIL IMPLANTS
No, you have to meet certain criteria for suiting trefoil implant procedure
Ability to maintain oral hygiene
Jawbone height – 13 mm
Jawbone width – 6-7 mm
Older adults whose jaw have been fully developed
