Whelby Endodontics
The service is focused on achieving some key goals to assist you and your patients when it comes to root canal therapy
- Assist you with difficult cases where successful endodontic treatment is challenging
- Work with your patient in an informative way so the understand the process and intricacies of treatment
- Return the patient to your care with enhanced probability of reliable outcomes in complex restorative cases.
- Take the stress off you with difficult endodontics
To do this we employ the latest techniques, instruments and materials and of course highly skilled staff. In the case studies presented below Fernando has highlighted the latest research backing the protocols we follow to achieve predictable results for your patients. It is important in complex cases not to encounter any of the possible pit falls that can lead to problems. The cases highlight these possible difficulties and how they can be overcome.
C RCT + Fiber Post
These are less likely to cause root fracture than indirect precious metal post cores (3) and leave the referring dentist a superb base for crown preparation.
The canal can be shaped with post preparation in mind to achieve the best long term results for your patients
Using the microscope magnification facilitates excellent surface preparation for bonding.
The use of pre-heated composites allows perfect adaptation of post material for best retention (4, 5)
Just ask on the referral form if you want a post prepared and fitted ready for your permanent crown restoration, or ask for more information

I Re-RCT + MTA
Often these cases were treated by apicectomy and retrograde root filling, which was not the ideal for patient comfort and recovery. (1)
Now with the use of the microscope and techniques in MTA placement it is possible to treat these cases with an orthograde approach (2)
Here we have a wide foramen that has been successfully treated placing a 3-5mm MTA seal apically
Patient are much happier to have this approach of treatment in these complex cases.

Multiple difficulties
The case here has difficulties of access and isolation due to position and subgingival decay, a second mesio-buccal canal (often impossible to detect without a surgical microscope) and severe curvature of the roots.
A pre-endodontic tooth restoration has been done to avoid per and post operative leakage (1)
The use of a surgical microscope enhanced the search of a present fourth canal, hard to detect without magnification (2), modern rotary instruments (3, 4) along with the latest irrigants activation devices (5) and obturation methods (6), make success in these cases more achievable
Let us help with the complex underlying difficulties and return the patient to your care for the pleasure of the final restoration
