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
LoCascio S, / Salinas, T PPAD 1997; Vol. 9, No.3: 357-370
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. ���������

Vertical Bone Loss To The First Thread
Tarnow DP, Cho SC, Wallace SS. J Periodontol 2000;71:546-549
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

Thus, Degree Of Bone Resorption Is Limited.
Even If 2 Implants Are Positioned Close To Each Other, Thanks To Platform Switching Concept,
Interproximal Bone Height Is Not Reduced After 1 Year.

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.”
Kan JY, Rungcharassaeng K, Lozada JL. Bilaminar Subepithelial Connective Tissue Grafts for Immediate Implant Placement and Provisionalization in the Esthetic Zone. J Calif Dent Assoc. 2005 Nov;33(11):865-71
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
