COURSE DESCRIPTION

There is no remaining controversy surrounding best practices in restoring Endodontically Treated Teeth (ETT) or which materials are best to use. The evidence is clear and unmistakable.

There are two separate courses offered on this subject. This course and Hands-on workshop which includes two days fully dedicated to teaching of the Bonded Composite-Post Build-Up Protocol .

This eye-opening course focuses exclusively on how to do Bonded Composite-Post–Core Build-up (BC-PCB) using endodontically treated teeth models and the 3M RelyX Unicem 2 Automix ,Self adhesive Resin Cement and 3M Rely X Fiber Posts.

In the restoring ETT, Dr. Abou-Rass considers complete sealing and building the pulp chamber and surrounding dentin structure with bonded composite with or without a post is biologically sound procedure and common sense action to Restore the ETT. He believes that endodontic treatment should be protected from bacterial coronal leakage with either Bonded Composite Build up or Bonded Composite- Post-Core Build up. This approach not only provides the physical foundation for proper restoration, but also prevents or reduces the risks of coronal leakage ,thus protecting the root canal obturation seal, sterility, and longevity.

A well-executed bonded composite- post -core build-up enables dental professionals to place the final restoration on the endodontically treated tooth with the most predictable, trouble-free, permanent and post-and-core foundation.

CLINICAL SKILLS & LEARNING OBJECTIVES

Pulp Chamber Preparation

  • Learn the single universal hole rubber dam application technique
  • Debridement of the clinical crown from fragile or questionable tooth structure and removal of restorative materials
  • Debridement of Pulp chamber walls and floor from GP, sealer and temporary cements.
  • Maintain retentive features in the pulp chamber and surrounding tooth structure
  • Finishing of GP filled canal orifices

Post Cavity Preparation (PCP)

A Standardized Pesso drill has 8mm Shank & 8mm Cutting Flutes. Only Size 2 & 3, are recommended to prepare the post cavity space (PCP) in the protocol.

  • Check that there is no wobble in the rotation of Pesso drill.
  • Insert the full 8mm fluted part of the drill into the orifice of the gutta-percha filled root canal
  • In multirooted teeth, select the straightest and longest root. Normally the palatal roots of maxillary molars and distal roots of mandibular molars or lingual root of upper bicuspids .
  • Fast speed helps to soften the Gutta Percha filling material so drill is run at fast speed upon entry. Pink GP should be coming out to assure you are on the right track. Dentinal filing indicates a warning to stop! GP has a soft feel where tooth feels hard.
  • Verify the PCP Length: 7-8 MM from canal orifice to apical Gutta-Percha level. The width is loose fitting of the # 2 or 3 Pesso drill.
  • Condense the apical gutta-percha with size ISO # 70 endodontic plugger
  • Use ultrasonic Instruments to debride remaining sealer and GP off the PCP walls

Fiber Post Selection.

  • Select Size Zero (0) 0r One (1) 3M Fiber Post, for all teeth. For Central incisors, you may use Size Two (2) fiber post.
  • Verify with periapical radiographic fit of the apical end of the post against the apical G-P. Adjust as necessary
  • Final Debridement of Post Cavity Preparation , and Pulp Chamber.

Post Bonding & Cementation

  • Acid-etch the PCP, pulp chamber, and coronal tooth structure. Rinse, dry the PCP with paper points and air to assure no etchant or moisture remains.
  • Use micro-brush to apply Scotchbond Universal Adhesive to the PCP, pulp chamber walls and floor and remaining tooth structure.
  • Use dry micro-brush to remove excess adhesive, air dry, and cure for 30 seconds.
  • Insert the endo tip of the automix syringe into the PCP and Inject 3M RelyX Unicem 2 Automix cement.
  • Coat the apical end of the post with 3M RelyX Unicem 2 Automix cement and place firmly in the PCP
  • Use micro-brush to Remove excess composite around the junction of post - canal office, and pulp chamber floor and walls.
  • Light-Cure the post for 30-60 seconds
  • Proceed to do the Composite Core Build-Up procedures with the same Rubber Dam in place. However, if better isolation is needed, remove the rubber dam.

Composite Core Build-Up

  • Use Tofflemire matrix or Auto-Matrix to isolate the tooth
  • Rinse and dry the tooth
  • Apply Scotchbond Universal Adhesive to the cemented post, pulp chamber walls and the remaining tooth structure
  • Build-Up the pulp chamber using incremental 1-2 mm layers of 3m Filtek Hybird composite (layering method)
  • Cure each layer for 30 seconds, Continue filling layers until coronal build up is complete
  • Assure perfect application of each layer before curing.

Composite build up finishing

  • Consider the Core Composite as a final restoration in light centric and excursive occlusion, with correct anatomic contour, proper interproximal contacts, no overhang or marginal defects.
  • The BC-PCB may be used as a permanent or provisional restoration according to treatment planning.
