Introduction
Upcoming meetings:
06/16     literature review
09/15     literature review
10/20    Virtual Treatment Planning
 

Today's speaker: Dr. Sam Strong, private practice in Little Rock, Arkansas, with emphasis on implant prosthetics, esthetic restorations, and sleep apnea treatment. Author, lecturer, adjunct professor University of Oklahoma College of Dentistry.

TAKING YOUR PRACTICE TO THE NEXT LEVEL WITH IMPLANT  PROSTHETICS  -  DR. SAM STRONG
A nine-page handout accompanied Dr. Strong's presentation.

Little Rock, Arkansas, is a microcosm of the entire United States.
Most of us make our living treating middle-class patients.

Important to first IDENTIFY the implant patient, don't treatment plan or quote fees without a prior treatment conference.
1. Diagnostic work-up = "heart and soul" of case acceptance.
    diagnostic casts: Dr. Strong recommends accu-gel system II (Ivoclar) as impression material
    face bow transfer (rare for Arkansas)
    dialogue with patient: obtain patient's goals and expectations; patients usually need to be educated about papillas
    FMX, pano, refer for CT, CBCT
    photographs: 9-11 for case analysis

2. Limited work-up
    individual P.A.'s, pano (?)
    diagnostic casts =  important to determine inter-arch space

3. treatment planning conference = VITAL! with treatment team, difficult to do in Southern California face-to-face,
     use duplicate models, duplicate radiographs, scheduled phone conference
    identify type of surgical template to be used
    prognosis, identify limiting factors, immediate vs. sequential, provisionalization needs, treatment time estimate
     treatment options, case limitations, risk factors, maintanence requirements
     (Dr. Strong feels the literature is ambivalent regarding the effect of smoking on implant treatment outcomes)
     fee estimates, financial options, informed consent

4. Dr. Strong's sample fees:
    initial exam:  $55
    diagnostic work-up:  $500
    interim appliance:  $900
    implant treatment:  $15000

Implant Considerations Checklist
 1. sequencing
 2. implant sites
 3. fixture data: size, length, spacing, splinting, cantilever?
    Anterior implant selection:
        head design (flat? scalloped?)
        subgingival depth
        papilla preservation / regeneration
        provisional (fixed? removable?)
        dual abutments?
        spacing/diameter/length
    Posterior implant selection
        implant length should be greater than or equal to coronal height of restoration
        evaluate bruxism / heavy wear
        when in doubt, SPLINT!

Nobelbiocare Direct Implant - one piece
    implant placed, minimally prepped, temporized
    re-prepped after osseointegration

direct vs. fixture-level impression (fixture-level is Dr. Strong's "work horse")
fixture-level impression requires ridgid tray, Dr. Strong recommends Axis Dental "Originate"

Question: "Do you ever give a ballpark fee estimate at the initial exam?" - Only in very small cases (single-unit)

Dr. Strong professionally filmed interviews with 30 of his patuients (hand  selected, not random), asked patient satisfaction questions. A film vignette of the interviews was presented.

Nobelbiocare is now promoting public education directly to the patient

IMPLANT RESTORATION OF THE FAILING DENTITION
Implant-supported FPD
    transfer impression = implant position transferred to master cast
    must confirm seating of impression coping with X-ray
    abutment connection screws protected by occluding access opening with light-body impression material
    Provisionalize 2-3 months to allow maturation of extraction site
    occlusal table narrowed in buccal-lingual dimension to center occlusal forces over implant
    Case Presentation
        62 yr old male, bilateral implant-supported FPD's
        knife-edge ridges were grafted
    post-op occlusal splints are recommended for large cases / bilaminar occlusal splint (soft in the middle)
    retrieval of provisionally cemented restorations:
        Improv cement (urethane-based): breaks away cleanly, 17% teflon - not a tenacious bond
            must lubricate (vaseline) casting and abutment
            use Richwill Crown Removers with Miltex 72-10C pliers (sometimes works with permanent crowns)

CURRENT THERAPIES FOR SLEEP DISORDER - SNORING
Currently, dentists may not treat sleep disorder / sleep apnea - only provide treatment with MD's prescription. Dentists may treat snoring.
Snoring: can usually be treated more quickly and predictably than apnea (def. more minimal breathing or stoppage of breathing)
Usually it is the spouse that will force patient to seek treatment
Treatment usually includes a weight loss program

Mechanical
    Constant Positive Airway Pressure (CPAP) very bulky, commonly prescribed by MD
    Positioning devices
    Oral appliances (reposition mandible forward, resulting in tongue being pulled forward)
        Snore guard - not good for bruxers
        Silent Night - breakage problems
        *TAP (Thorton adjustable positioner) -  Dr. Strong's favorite
            lab cost = $250
            ortho changes (posterior open bite) are rare but possible - should include in informed consent
            should include physical therapy / exercises in morning to re-set condyles
            locater abutments (Zest) can be added to TAP to fit overdenture abutments
Surgical
    several surgical treatments to enlarge airway opening, including removal of uvula, are available.

DENTAL IMPLANT AND ALTERNATIVE OPTIONS
    Dr. Strong has created a patient info DVD which is available for purchase (www.strongdds.com , 1-866-826-4452)
    Exerpts from the DVD were presented

Extract a tooth - walk out with:
    1. flipper?
    2. provisional crown with Nobelperfect immediate placement implant ("scalloped" for papilla/bone preservation)

Scripting For Staff
    Staff needs to be reminded daily of "office mantra" . . . "scripts" should be available at every telephone so patient inquiries
    can be answered accurately

    Advise patient that atrophy will proceed if treatment is delayed

    10-year survival rate on crowns and FPD on natural teeth = 75%
    10-year survival rate on crowns and FPD on implants  =      95%

Standard of Care for mandibular edentulous patient:
    2 implants with attachment overdenture
        Locator attachments / Zest anchors are user-friendly
    bar-retained overdenture
        outline of appointments / procedures given in hand-out

Fees for Implant Treatment
    An example (4-implant / bar) overdenture was presented to illustrate a method by which Dr. Strong establishes a fee:
    1. Lab fee (surgical template $150, baseplate 135, cast bar 900 (AR) -2000 (CA), process denture with teeth 450, metal
                     reinforcement casting 150, clips/housings 75, tax, shipping)  = $1900
    2. implant components (implant copings 200, analogs 100, abutments 800) = $1100
    3. overhead: 4 hours chairside + 1 hr total for adjustmnents first 6 months = 5 hours X $400/hr = $2000
    4. profit: profit/hour for 5 hours = $500/hour X 5 hours = $2500
    5. FEE = lab fee + overhead + profit = $1900 + $1100 + $2500 = $7500

    Use of locater attachments (Zestanchor.com) instead of bar/clip reduces procedure by one appointment (no bar try-in), decreases costs by $1500.

Meeting adjourned at 9:00 PM
