The Transition from Teeth to Dental Implants

Challenges: ➡ Management of patient expectations

✦ Design Considerations •  Fixed prosthesis vs. removable prosthesis

-  No flange vs. flange

The Transition from Teeth to Dental Implants

It is imperative to plan for long term prosthetics. As a general rule, if a fixed restoration is fabricated for a partially edentulous clinical situation, then the patient is committing to additional fixed implant restorations with similar prosthetic designs when additional teeth are lost in the future. The reverse treatment scenario may also apply.

The Transition from Teeth to Dental Implants

If you plan for a fixed crown and bridge restoration now, then you will most likely be providing the patient with additional fixed restorations in the future. If you plan for a removable restoration now, then you will most likely transition the patient into a larger removable prosthesis in the future.

  Overdentures •  15 – 17 mm

  Hybrid Dentures •  13 – 15 mm

  Ceramo-Metal •  9 – 13 mm

Vertical Space Requirements

The Transition from Teeth to Dental Implants

Fixed with no flange

✦ Step By Step “Phased” Treatment Plan: 1) Extraction of all teeth with poor prognosis with initial provisionalization 2) Impressions and diagnostic wax up to full contour of all missing teeth 3) Fabrication of implant radiographic guides or surgical guides 4) Placement of all endosseous implants 5) Integration and uncovery as needed 6) Diagnostic wax-up to full contour and complete provisionalization 7) Final transfer impressions and fabrication of definitive prostheses 8) Insertion of definitive prostheses 9) Maintenance / recall

The Transition from Teeth to Dental Implants

➡ Challenges: ✦ Management of patient expectations

•  Functional Expectations

•  Functional Realities

•  Comfort

The Transition from Teeth to Dental Implants

➡ Challenges: ✦ Management of patient expectations

•  Functional Expectations -  As a general rule, patients expect to function as

well as or better than they did before they lost their natural teeth

-  These expectations may not be a reality due to many factors: ‣  Case design/implant number ‣  Occlusal material ‣  Prosthesis design considerations: Fixed vs.

Removable

➡ Challenges: ✦ Management of patient expectations

•  Functional Realities -  Implant Assisted Overdentures ‣  2 implant assisted mandibular overdenture

functions like a denture with added retention ‣  4 implant assisted maxillary overdenture functions

like a denture with added retention ‣  Food trapping probable -- PAIN

The Transition from Teeth to Dental Implants

➡ Challenges: ✦ Management of patient expectations

•  Functional Realities -  Implant Supported Overdentures

‣  No tissue support -- functional support may resemble fixed designs

✓ Locking bar attachments most retentive design -- most like fixed design

‣  Prosthesis remains removable -- psychological limitations

‣  Food trapping possible -- NO PAIN

The Transition from Teeth to Dental Implants

➡ Challenges: ✦ Management of patient expectations

•  Comfort -  As a general rule, patients expect their level of

comfort to be as good as or better than it was before they lost their natural teeth.

Biologic Width…

Evidence Based Research

 Epithelial attachment and connective tissue form the physiologic attachment apparatus around teeth

• Gargiulo AW, J Perio 1961; 32:261-267

• Vacek JS, I J Perio Rest Dent 1994; 14:155-165

Conclusion: There appears to be a minimum of 3mm tissue

thickness separating the bone from the oral environment with 2mm being the area of

attachment tissue (Biologic Width).

The 3mm of Required Tissue Depth and 2mm of Biologic Width Around Natural Teeth

1mm Sulcus

1mm Epithelial Attachment

1mm Connective Tissue Attachment

What Impact Does The Biologic Width And Other Dynamics Have On Crestal Bone Remodeling?

Evidenced Based Research

Bone Level Is Determined By:

  Soft tissue thickness of approximately 3mm ���(1mm sulcus, 2mm biologic width)

  Exposure to the oral environment, combined with the location of the Implant-Abutment Junction (IAJ) and of the Inflammatory Connective Tissue (ICT) Infiltrate

  Surface Topography

Biologic Width Surrounding Implants

 The implant-abutment junction (IAJ) being exposed to the oral environment, triggers a cascade of tissue reactions:

– The 1mm of connective tissue moves apically to protect the bone from potential irritants

– The connective tissue will always cover itself with about 1mm of epithelium

– Therefore, the 2mm biologic width forms below the ���micro-gap

– The bone will remodel to allow for this more apical formation of the biologic width.

Ericsson I, et al. Clin Oral Impl Res 1996;7:20-26.

Abutment and Implant Junction Inflammatory Cell Tissue (ICT) Infiltrate

Summary of Biologic Evidence  When open to the oral cavity, the bone needs approximately

3mm of tissue for protection, this is the first prerequisite.

 The presence of either an implant/abutment interface or a rough smooth interface may establish an inflammatory zone with a vertical dimension of 0.5mm to 1.1mm and a lateral dimension of .20mm to .40mm.

 There is a biologic need to maintain an inflammation-free connective tissue zone of about 1mm apical to the inflammatory zone above the bone.

 The combination of these two numbers approximates the classic 2.0mm number reported in the literature as the vertical distance from the platform to the bony crest and appears to explain the “angular” crestal remodeling configuration. ���������

When Implants Were Closer Than 3mm, Crestal Bone Loss From The

Implant Shoulder Was 1.04mm

Vertical Bone Loss To The First Thread

Vertical Bone Loss To The First Thread

When Implants Were Closer Than 3mm, Crestal Bone Loss From The

Implant Shoulder Was 1.04mm Vertical Distance From The Crest Of Bone To The Height Of The Interproximal Papilla Between

Adjacent Implants Tarnow D. et al, J Perio 74:12 1785-1788 Dec. 2004

The findings indicate 2-4mm (3.4mm average) of soft tissue height can be expected to cover the inter-implant crest of

bone.

This represents a deficiency of 1 to 2mm of what is needed to duplicate the interproximal papillae of the adjacent teeth.

Platform Switching™

 The placement of one size smaller prosthetic component on an implant seating surface

 The objective is to move the implant-abutment connection in from the implant shoulder

With The Certain® Prevail™ Implant, By Moving The Micro- Gap In From The Implant Shoulder, The

Bone Is Shielded From The ICT And Confined To The Top Of The Implant

Platform.

Clinical Case Will soft tissue follow the bone around the implant or the adjacent teeth?

Are there any benefits to platform switching with single tooth implants if we

can maintain at least 1.5mm of space between the implant platform and the

adjacent teeth?

Biotypes

Thick vs Thin

Biotype Thick / Flat

Biotype Thin / Scalloped

Thick Flat Biotype

Thin Scalloped Biotype

BIOTYPES Thin / Scalloped Biotype

• Distance from peak of papilla to facial gingival margin is large

• Short contact area towards the middle to incisal third

• Tooth form is tall and tapered with large CL/CW ratio

• Thin band of attached mucosa

• Probably relates to initial tooth eruption through thin band of attached tissue

• Thin facial bone

Thick / Flat Biotype

• Distance from papilla height to facial gingival margin is small • Long broad contact areas from incisal to cervical third • Tooth form is short and square with small CL/CW ratio • Thick band of attached mucosa

• Probably relates to initial tooth eruption through a thick band of attached tissue • Thicker facial bone

Thin Biotype

➡ Gingival recession common with bone level changes

➡ Tissue tears easily and does not heal well

➡ Thin tissue shows underlying metal ➡ CT grafts better than hard tissue for

final augmentation to thicken tissue for better color.....converts thin to thick (Kan et al)

“Facial gingival recession of thin periodontal biotype seems to be more pronounced than that of thick biotype. Biotype conversion around both

natural teeth and implants with subepithelial connective tissue graft has been advocated, and the resulting tissues appear to be more resistant

to recession.”

Thick Biotype

➡ Bone levels change with less recession ➡ Scars are easier to hide ➡ Hard tissue augmentation for flat ridges

works well at time of implant placement
