Case facts

Patient: 

A male patient in his 60s with failing teeth in both jaws requiring extraction.

Clinical problem: 

The patient has failing teeth in both jaws that need extraction. Post-extraction and during the healing process, there is significant atrophy of the upper and lower jaw, resulting in reduced bone volumes both horizontally and vertically. Additionally, there is limited adherent gingiva in the lower arch.

Clinical situation:

Start with the mandible and extract the teeth and the placement of four implants to enable immediate full-arch rehabilitation.

Treatment plan: 
  • Extraction of six teeth in the lower jaw.
  • Immediate placement of four implants with Multi-Unit Abutments.
  • Provisional screw-retained bridge placement during the preparation of the final prosthesis.
Products: 

4 Neoss ProActive Tapered implants
2 Multi-Unit Abutment 3.0 mm
2 Multi-Unit Abutment 30° 3.0 mm
4 Multi-Unit Impression coping Open tray 6 mm
4 Multi-Unit Healing Cap

Conlusion:

The patient received a screw-retained bridge in the lower jaw 48 hours after surgery. In the upper jaw, the patient was rehabilitated with a removable prosthesis. The patient is scheduled to return for the placement of the final prosthesis and full-arch treatment for the upper jaw at a later date.

Step by step

Step by step

  • Sicuro MUA case fig 1
    Figure 1.

    Pre-treatment panoramic radiograph. The patient had conventional, tooth-supported bridges in both jaws. All teeth were failing and in need of extraction.

  • Sicuro MUA case fig 2
    Figure 2.

    Post-extractive panoramic radiograph. The patient had severe atrophy of the upper and lower jaws, little attached gingiva in the lower arch with reduced bone volumes both horizontally and vertically.

  • Sicuro MUA case fig 3
    Figure 3.

    Panoramic radiograph at time of implant placement, four months after extraction. Four Neoss ProActive Tapered implants were placed in the lower jaw. The two posterior implants were tilted to minimize bridge cantilevers.

  • Sicuro MUA case fig 4
    Figure 4.

    Neoss Multi-Unit abutments were placed at the time of implant placement . Angulated (30°) Multi-Unit abutments were used on the tilted posterior implants, and straight Multi-Unit abutments were used on the anterior implants.

  • Sicuro MUA case fig 5
    Figure 5.

    A conventional impression was taken after tissue closure at time of surgery. Open impression technique and Multi-Unit Impression Copings Open tray were used.

  • Sicuro MUA case fig 6
    Figure 6.

    Impression acquired immediately after surgery.

  • Sicuro MUA case fig 7
    Figure 7.

    Multi-Unit Abutment Healing Caps were placed on the Multi-Unit abutments, and the soft tissue repositioned and sutured around the Healing Caps to achieve more attached gingiva on the buccal side.

  • Sicuro MUA case fig 8
    Figure 8.

    The model was scanned and a provisional full-arch restoration designed using CAD. Note the parallel interfaces achieved using angulated Multi-Unit abutments.

  • Sicuro MUA case fig 9
    Figure 9.

    The dental laboratory milled a provisional screw-retained bridge from reinforced PMMA and bonded onto Multi-Unit Provisional Abutments.

  • Sicuro MUA case fig 11

    Try-in of the provisional bridge on the model. Occlusal view. Note the short cantilevers achieved using tilted posterior implants.

  • Sicuro MUA case fig 12
    Figure 12.

    The patient received the screw-retained bridge in the lower jaw 48 hours after surgery. In the upper jaw the patient was rehabilitated with a removable prosthesis.

"I have used Neoss4+ solutions for more than 10 years and every day me and my team are happy to do surgery and deliver prostheses. The new Neoss Multi-Unit Abutment makes the Neoss4+ concept even more accessible, flexible and simplified."
