1. The Novaloc® Retentive System for hybrid dentures The Straumann® Novaloc® Retentive System for hybrid dentures offers an innovative car- bon-based abutment coating (ADLC1) with an excellent wear resistance, overcoming up to 60° implant divergence. Both the straight and 15° angled abutments are available in various abut- ment heights, covering a broad range of clinical implant situations.
ѹ Torque the abutment to 35 Ncm using the Ratchet, the Torque Control Device and the SCS Screwdriver. Step 3 – Sealing the screw channel of the Novaloc® Angled Abutment ѹ Use Teflon and composite in order to seal the screw channel of the Novaloc®...
2.2.1 Master cast – abutment-level impression Step 1 – Inserting the Novaloc® Model Analog ѹ Insert the Novaloc® Model Analog into the Novaloc® Forming/ Fixing Matrix (see chapter 3 Using the Novaloc® Tools). For straight abutments use the straight, for angled abutments the angled analog.

2.2.2 Finalizing the new Novaloc® overdenture Step 1 – Placing the Novaloc® Mounting Collar and Matrix Housing ѹ Place white Mounting collars on all Novaloc® Model Analogs. ѹ Place the Matrix Housing incl. preassembled Mounting Insert onto the Novaloc® Abutments.
Retention Inserts ѹ Select the appropriate Novaloc® Retention Insert (see chapter 4 Special featured Novaloc® components). ѹ Insert the Novaloc® Retention Inserts to the Matrix Housing using the Mounting and Demounting Tool for Retention Inserts (brown) (see chapter 3 Using the Novaloc®...
Removing the Novaloc® Matrix Housing from an overdenture 1. Heat the Novaloc® Matrix Housing Extractor head (Fig. 2). 2. Apply the hot Novaloc® Matrix Housing Extractor to the Matrix Housing and let the heat transfer for 2 – 3 seconds melting the resin around the Matrix Housing.
3.3 Novaloc® Mounting and Demounting Tool for Retention Inserts (Fig. 11) Mounting the Novaloc® Retention Insert 1. Pick up the Novaloc® Retention Insert with the gripper end of the Novaloc® Mounting and Demounting Tool. The Novaloc® Retention Insert will lock on to the tool (Fig. 12).
4. Special featured Novaloc® Components Novaloc® Retention Inserts The Novaloc® matrix system allows for a prosthetic insertion of up to +/- 20° divergence, meaning 40° between two Novaloc® Abutments. Note: Retention insert color Retention red, extra light approx. 300 g It is recommended to use the light retention force first (white).
6.1 Appendix A 6.1.1 Chair-side modification of an existing lower denture into an overdenture supported by Novaloc® Abutments For an existing well-fitting and well-functioning lower complete denture, the Novaloc® Retentive System can be used in a chair-side procedure. Caution: It is a prerequisite however, that the lower complete denture does not need to be relined by a dental technician.

Once the resin has cured, remove the lower complete denture from the mouth and discard the white Novaloc® Mounting Collars. Put the lower complete denture in hot, but not boiling, water. Place...
If the lower complete denture’s fit is inadequate (poor adaptation to underlying tissue) after surgery and major adjustments are necessary, indirect relining of the mandibular denture is necessary. This means that relining and insertion of Novaloc® Matrix Housings incl. Mounting Inserts are performed by the dental technician immediately after border mold impres- sion-taking.

Insert the lower complete denture into the patient’s mouth and check the clearance. The Matrix Housings on the abutments should not touch the denture base. Reconfirm space using wash impression silicone. Adjust the denture base to seat passively in occlusion with- out touching the Matrix Housings.

Once the impression material has cured, remove the lower com- plete denture with the Novaloc® Forming/Fixing Matrices from the mouth. If the Novaloc® Forming/Fixing Matrices did not remain in- side the impression, carefully reseat them into the reline impression. Send the mandibular denture to the dental technician to reline it, in- tegrate the Matrix Housings and convert it into an overdenture.
