Using novel adjunct techniques
to help treat a patient’s
nonrestorable fractured teeth
by Dr. Ed Kusek
This case involved a 41-year-old man who
had a syncopal episode while watching a
baseball game and fell forward on his face,
causing trauma to the right cheek (zygoma,
infraorbital and auricular) and anterior maxillary
teeth. He was seen on site by a paramedic,
and as a patient of record was seen the next day
at the dental practice.
A full CBCT (Fig. 1) and photographs of the
facial injuries (Fig. 2) were taken at the initial
appointment. Evaluation of the CBCT showed
horizontal fractures of Teeth #7 and #8 below the
alveolar crest, with fractures into the pulp tissue
making the teeth nonvital and nonrestorable by
traditional methods. Because the patient was in
pain, he was interested in a quick transition.

Treatment plan
1. Temporary root canal and place
posts to lute the fractured incisal
portions of the teeth (Fig. 3) to
allow the patient to function
without pain. Scan teeth to fabricate
an Essix appliance (Dentsply
Sirona) to replace #7 and #8 after
extractions.

2. Extract #7 and #8 and place
immediate implants. Because of
the time constraint, I would be
unable to extrude #7 and #8 to
gain better tissue and bone support,
and because of the area of
the fracture, I could not perform
socket shielding. The patient
would wear the Essix appliance
for the healing time of three to
four months.
3. Uncover implants with the use
of a CO2 laser, place scan bodies
(TruAbutment), and scan
area (Trios, 3Shape) to create a
gold-colored Atlantis abutment
(Dentsply Sirona) and a fabricated
lithium disilicate crown.
4. Seat the case in three weeks.
5. Maintenance.
Treatment considerations
- A salivary diagnostic test
(Oral DNA Labs) to determine if
the patient is susceptible to periodontal
disease.
- Photobiomodulation treatment
to decrease the treatment time.
- Use of an erbium laser to create
decortication and regional
acceleratory phenomenon (RAP),1
which can increase bone-toimplant
contact (Fig. 4).
- Use of a CO2 laser to uncover
implant and allow maximum connective
tissue around the implant.
- Use of an Nd:YAG laser (Deka
Dental Lasers) for high-intensity
laser treatment (HILT) to increase
bone formation in site #8.2,3
- Use of aqueous ozone4 (Biosure)
to disinfect the osteotomy site
before implant placement.

CASE REPORT
Emergency root canal
Because of a scheduling issue in the
practice, it wasn’t possible to place
implants surgically right away, so the
patient was treated for temporary root
canals to allow him to function without
pain. He was given 1 cc of local
anesthetic with 20 mg of lidocaine
and 10 mcg of epinephrine, then 4 cc
of anesthetic with 40 mg of septocaine
and 5 mcg of epinephrine.
I drilled to access the pulp chamber,
verified the length with a Shofu apex
locator and a periapical radiograph,
then used ProLube root canal conditioner
(Dentsply Sirona) and 10 cc of
aqueous ozone (BioSure), and dried
with a cannula (Ultradent), then paper
points, to remove any liquid. The
canals were then filled with Endo-Eze
MTAFlow (Ultradent) and GuttaCore
obturators (Dentsply). After a periapical
radiograph to verify the position,
I placed two Flexi-Posts (Essential
Dental Systems) and used Mosaic
composite (Ultradent) to bond the
natural tooth to each post (Fig. 3).
Occlusion was checked, adjusted and
polished, and photobiomodulation
was performed with an Evo laser
(Ultradent) to decrease postoperative
pain, swelling and the healing time for
the patient.
Implant placement
One month later, when the schedule
allowed an opening to place implants,
the patient was treated to surgically
place implants in place of #7 and #8.
IV access was completed in the
patient’s right antecubital fossa, in
which blood was drawn to get enough
samples to centrifuge to create
platelet-rich fibrin (PRF), which would
aid healing by using the patient’s own
bone morphogenic proteins.5 Drugs
administered: 20 mcg of dexmedetomidine,
5 mg of midazolam, 50 mcg
of fentanyl, 8 mg of dexamethasone
sodium phosphate, 40 mg of Solu-Medrol (IM) and 1 g of cephalosporin
in total on completion of the sedation.
The teeth were extracted with the
use of periotomes (Karl Schumacher)
and forceps, followed by a flap procedure
reflecting tissues from #6 mesial
to #9 distal with use of a 10,600-nm
CO2 laser, 0.5 mm spot size, for about
one minute. This involved no releasing
reflection, to help keep the facial
plate attached to the periosteum that had been fractured in the accident.
I then used Densah drills (Versah) in
reverse mode and an Er,Cr:YSGG laser
(Biolase) to decorticate the bone to
improve bone-to-implant contact5 and
disinfect the osteotomy site6 (Fig. 4). The area then was rinsed with
30 cc of aqueous ozone (Fig. 5).
I seated a 3.3-by-13-mm implant in
site #7 and a 4.2-by-13-mm implant in
site #8 (Ditron), then placed Bio-Oss
collagen (Geistlich) soaked in PDF
plasma (Fig. 6) into the gaps left from
the sockets. This was followed by PRF
membranes (Fig. 7) over this site and
closure with 3.0 PTFE sutures (Salvin).
Next, I treated the surgical site, the
right and left submandibular lymph
nodes, and the right and left subclavicular
lymph nodes with photobiomodulation
(PBM), and de-epithelized tissue
with the erbium laser (Fig. 8) to speed
the healing process. Then, the Essix
appliance was seated, out of contact
with soft tissues.

Follow-up visits and treatments
One week after implant placements
(Fig. 9), the patient’s level of healing
was evaluated, and I again performed
PBM over the surgical site and lymph
nodes. One week after that, the
sutures were removed and PBM was
performed again.
Fig. 9
Three months after implant
placement (Fig. 10), a new CBCT
was taken to determine the level of
healing (Fig. 11). With topical and
local anesthetic, a 10,600-nm CO2 laser
was used to uncover the implant sites
(Fig. 12), starting on the palatal side to
allow adequate attached tissue on the
facial aspect of the implants. I used
scan bodies (Fig. 13) that fit a 3.3-mm
internal hex, which are standard from many types of implants, but a radiograph
was taken to confirm the scan
bodies were seated correctly (Fig. 14)
to the base of the implant. After the
scan bodies were removed, I placed
Consepsis antibacterial solution
(Ultradent, Fig. 15) in the sites, followed
by healing abutments (Fig. 16)
to allow healing by secondary intention.
A facebow (Fig. 17) was taken
with the Panadent system.

Three weeks after the uncovering,
a gold-colored Atlantis abutment was
seated (Fig. 18) and tightened to 35 N
of force twice, allowing two minutes
to lapse to accommodate metal relaxation.7 Consepsis was placed (Fig. 19)
into the implant site before seating the
custom abutments. The area was isolated
with an Umbrella (Ultradent) to
seat FirstPlug material (35 N) to seal
access, and a photograph was taken
(Fig. 20) to record the access point if
needed for future reference.
I used hydrofluoric acid for one
minute on the intaglio surface, then
phosphoric acid for 20 seconds. Silane
was placed and allowed to dry for one
minute before Peak universal bond
(Ultradent) was lightly coated on the
intaglio surface and eCement (Bisco)
was used to lute the crown. The case
was seated (Fig. 21) before a periapical
radiograph was taken (Fig. 22)
to evaluate if there was any cement
left around the crown. After it had
been removed—confirmed with a new
radiograph—occlusion was adjusted
as needed and polished until it was
satisfactory to the patient (Fig. 23).
Two weeks later, during occlusal
and tissue evaluation, it was determined
to use an Nd:YAG laser to help
increase bone formation at Site #8,
because bone there had been fractured
at the time of the accident and
appeared to be immature at this time.
The patient had no pain to function in
all excursions.
Conclusion
The patient had an accident in which
he passed out because of heat stroke.
(After a full-head CT scan, it was
determined there was no other reason
for the patient to have lost consciousness
during a baseball game.) Doing a
quick root canal therapy allowed him
to function without pain until he was
able to get scheduled in the office.
The case shows a few different
adjuncts to implant surgery that most
offices do not incorporate:
- Aqueous ozone disinfects bacteria
and viruses in 15 seconds.
- An erbium laser also has shown to
be a good disinfectant in osteotomy
sites where bacteria may still
be present.
- Photobiomodulation can speed
healing time and decrease postoperative
discomfort.
- HILT utilized from Nd:YAG
(Fig. 24) also allows bone to heal
faster than traditional methods.
Fig. 24
I hope other clinicians will use some
of these techniques to increase their
success in implant dentistry.
