Dental Implant Home Care

Before, during, and after restoration

by Susan Wingrove, RDH

Good oral hygiene must take place before, during, and after 

placement of dental implants to ensure the health of the implant.

Patients are concerned about what kind of maintenance their 

implants will require. Do they brush and floss their implants like

regular teeth? Does food get underneath the fixed implant bridge 

or prosthesis? Patients look to their hygienists to address these 

concerns and help  them with an individualized home-care routine.

The tissue surrounding the implant should appear pink, firm, and keratinized
with no signs of infection. The peri-implant soft tissues (permucosal seal) that
separates the connective tissues surrounding the implant from the outside 
environment should be  keratinized tissue . The absence of 
keratinized tissue has been documented to be more susceptible to pathogenic 
bacteria thus leaving the implant vulnerable to peri-implant disease. The 
success of the implant depends directly on the health of this seal, and the 
hygienist's goal is to educate the patient on how to obtain  keratinized tissue 
and maintain a healthy  permucosal seal.

This reinforces the point that home-care must begin immediately and, if
possible, before  the implant is placed to maintain a healthy field and for
 optimal healing.
Once the implant is exposed to the environment, loaded (occlusal forces)
and restored  a salivary pellicle is formed followed by 
bacteria with the formation of biofilm. The elimination of 85% of 
plaque/biofilm on a daily basis is critical to the overall health of the implant.
Hygienists can prepare patients by providing home-care recommendations
based on the  individual treatment case. This begins with post-surgical
home-care guidelines to ensure  the patient feels comfortable and confident 
until they return for routine implant maintenance.  Always verify 
recommended guidelines with the implant  surgeon's recommendations.

Knowledge of the implant titanium surface is necessary to fully understand
what oral hygiene recommendations and products to present to patients. 
After 1990, a definite switch from smooth titanium alloy surface to a rougher
implant surface transpired, which has proven to accelerate osseointegration. 
The addition of surface coatings to create roughness with plasma spraying, 
grit blasting, and etching has also proven to raise the bone-to-implant contact 
and accelerate osseointegration.
To help the patient protect their implant(s), their investment, patients need
 to be aware  of the following key points on choosing safe home-care products.
 First the product  (for example, toothpaste or gel) needs to be low-abrasive to 
not scratch the surface of any exposed surfaces of the implant (exposed threads,
 for example). Avoid dentifrice with stannous fluoride, sodium fluoride (APF >3.0),
 baking soda, stain removers, and smoker's toothpaste.
Companies are researching low–abrasive dentifrices that are effective yet safe
for  implants, natural teeth, and completely edentulous implant patients 
(Colgate, Procter & Gamble, and Rowpar among others). Ramberg et al. 
reported that  Colgate Total in a double-blind, randomized, parallel-group 
clinical (in vivo) trial with 59 participants concluded that brushing with Colgate
 Total twice daily reduces bleeding  on probing adjacent to implant sites in a 
three- and six-month period with proven results of reducing plaque bacteria
 to help prevent peri-implant disease.
Secondly, products should not irritate the permucosal seal,9 or corrode and/or
etch the titanium.10-11 A high fluoride concentrate of > 3.0 sodium fluoride, 
combined with a low  PH, will remove the oxide layer on implants and can 
make the titanium surface anti-corrosive. Once this layer is removed, the 
implant is prone to corrosion. Stannous fluoride can cause etching, roughness 
on implants, and their esthetic restorations.

What toothbrushes and interdental products are best to use with implants?
Several studies have been conducted regarding what type of toothbrush is most
effective for implants. The results show no significant difference between sonic,
electric, or manual toothbrushes. The main focus needs to be on adaptation to 
the prosthesis  and the patient's dexterity. Instruct the patient to brush the 
implant(s) twice daily to remove bacterial plaque with a low-abrasive dentifrice. 
A soft toothbrush should be used ; options include a manual brush, electric, or 
sonic brush (examples include Oral-B Triumph, Sonicare, and Waterpik Sensonic 
Plus), Sulcabrush, or end-tuft brush.

Nylon coated interdental brushes/ proxabrushes are also an excellent
alternative to clean especially tight and hard-to-reach areas around implants 
and prostheses. Nylon only interdental brushes (no metal wire) are necessary
 to prevent scratching the implant or  prosthesis. The interproximal brushes
 such as I-Prox P or I-Prox Plus work extremely well and can be dipped in 
non-alcohol antimicrobial rinse or gel. It is extremely  important to brush
under, around, and in the peri-implant crevice circumferentially 

Floss

There are many types of floss on the market, and generally it is highly
recommended to use unwaxed tape or implant-specific floss in order to protect 
the tissue surrounding the  implant. Alternatively for a bar-retained prostheses, 
full fixed retained prostheses, or wider interproximal spaces, a floss threader or 
a specialized floss that has a built-in threader is necessary.

To floss the implant, use dental tape and insert the floss in contacts on both
 sides of the  implant. Wrap in a circle and crisscross in front, switch hands, 
and move in a shoe-shine  motion into the peri-implant crevice, which is 
highly susceptible to inflammation /peri-implant disease due to biofilm.
In addition, antimicrobial mouth rinses may be recommended, especially
if inflammation  is present or if the patient has dexterity problems, and 
difficult-to-reach areas. If the patient is prone to inflammation, the use 
of an antimicrobial rinse, in conjunction with a  rubber tip stimulator, 
may be recommended to inactivate bacteria substantive.

Oral irrigators/Water Flossers

It is highly recommended for patients to use oral irrigators for the
reduction  of plaque/biofilm, inflammation, and hard-to-reach emergence 
profiles around implants13,14  .Instruct the patient to use 
a nonmetal  tip one to two times daily, and, if inflammation is present, add 
a diluted non-alcohol antimicrobial rinse (chlorine dioxide or chlorhexidine 
gluconate).
Studies using oral irrigators with implants for oral hygiene reveal that
Waterpik Water Flosser is the only oral irrigator to date to be proven safe 
and effective with dental implants. A study was conducted to compare
 rinsing with 0.12% CHX to using a Waterpik oral irrigator with 0.06% CHX. 
The irrigation group using the soft rubber tip (PikPocket Tip, ) 
at lower pressure was 87% more effective in reducing  bleeding and three
 times more effective in reducing gingivitis than the rinsing group.

Another study of oral irrigation and floss revealed that the Waterpik Water
Flosser with  the standard tip with three bristle filaments (Plaque Seeker Tip,
 see opening page) used  at medium pressure around implants was 81% more 
effective in bleeding reduction  compared to 33% using floss.16 These
specialized tips are very effective for implants and to deliver anti-microbial 
rinse around difficult-to-reach prostheses (All-on-4, full-fixed prosthesis, 
for example) in a prevention of peri-implant disease.

Water irrigation in conjunction with diluted non-antimicrobial rinse has proven
to be extremely helpful for full-fixed and removable prostheses to remove daily 
biofilm and prevent inflammation if used on a daily basis. Waterpik makes a 
compact Traveler Water  Flosser unit, which is my personal favorite to 
recommend ensuring patients continue their home-care routine at home and 
away .

Stimulators

Stimulators are coming back into vogue with implants and regenerative
procedures.  Remember healthy keratinized tissue is the key to a healthy 
permucosal seal surrounding the implant. Stimulators are the ticket to 
achieve this, particularly in full-fixed, supra-structure implants, as well as 
implants that retain over-dentures (bar-retained implants). Examples of 
stimulators are rubber tip stimulators producted by multiple manufacturers 
and Soft Picks by Sunstar Americas .

Instruct the patient to place the tip of the rubber-tip stimulator so it lays flat
against the  gum tissue, not poking in the tissue, with pressure roll to massage
and stimulate the tissue. The tissue will blanch or change to a lighter color 
when the correct pressure is applied.
A generalized home-care routine for implants is listed in Table 2 to be
modified to individualize the patient's home-care routine. For an All-on-4 
full-fixed case, add the use  of a water irrigator unit twice daily with a 
non-alcohol antimicrobial mouth rinse in 1:10 dilution to the home-care 
guidelines.
For removable prosthesis, the patient should use the guidelines in Table 3.
Note that a specific denture cleaner may be recommended for the overdenture.
Plaque and bacteria  can also accumulate on the inside of the overdenture,
causing wear to the attachments  and oral–systemic health complications
for the patient. Educate the patient on how to  do a visual check for attachments
(O-rings, locator caps, and clips) and the importance of these attachments for
retention. If attachments are worn or missing they will need to  be replaced. 
O-rings and locator caps should be replaced once a year and clips as needed.
Hygiene tip: Note the color and attachment type (O-ring, locator or clip) and
record in  the patient's chart .

For implants with peri-implant disease, mucositis, and/or implantitis, follow
the home-care guidelines, but add antimicrobial therapy. Use Soft Picks, 
interdental, end-tuft or Sulcabrushes dipped in non-alcohol antimicrobial 
rinse or CHX gel (compounded by compound pharmacies). "Soak" or apply 
the antimicrobial to the infected area twice daily and continue with this 
protocol until three to six week re-evaluation.
This article gives the latest home-care products available currently;
however, the technology and implantology is constantly changing. Research
 and evaluate home-care  products that are safe with clinical research done
on implants. Patients rely on their  dental professionals for recommendations
on what products to use and to present  them with a safe daily home-care 
routine.
