Abstract

The permanent maxillary canine is the second most

frequently impacted or displaced tooth. The standard

treatment for an impacted canine includes, among

other things, surgical exposure and orthodontic align-

ment. Surgical techniques for this procedure vary de-

pending on whether the tooth is labially or palatally

impacted, while orthodontic techniques vary accord-

ing to clinical judgment and experience. Autotrans-

plantation is a treatment alternative for impacted ca-

nines with complete root formation. The success of

tooth transplantation depends on the vitality of the

periodontal ligament (PDL) attached to the donor

tooth, and its viability decreases when it is exposed

extraorally. This article reports on maxillary canine au-

totransplantations combined with connective tissue

grafts (CTGs) and orthodontics. The recipient me-

siodistal space was created orthodontically and the

recipient socket was prepared using dental implant

drills. Following transplantation, bone defects were

grafted using guided bone regeneration (GBR). At

4 years post-transplantation, the soft tissue level was

stable and periapical radiographs showed a practically

normal contour of the alveolar crest around teeth 13

and 23. The two permanent canines presented no

root resorption and ankylosis, and no signs of inflam-

mation or bleeding were observed. The procedure

used in this case report demonstrates that canine

transplantation combined with GBR, plastic surgery

procedures, and orthodontic treatment may yield ac-

ceptable and predictable esthetic results.

or ectopic site and the creation or modifica-

tion of a socket at the recipient site. This is

followed by replantation of the tooth into the

ideal three-dimensional (3D) position within

the alveolus.

The prognosis of autotransplanted teeth

is determined by several conditions includ-

ing patient age and gender, developmental

stage and root anatomy of the donor tooth,

adequate alveolar bone support, atraumatic

surgical technique, adaptation of the donor

tooth to the recipient site, method of fixa-

tion/stabilization, and postoperative care. It

goes without saying that the clinician’s ex-

perience is equally essential.10 However, the

most critical factor for long-term success is

to maintain healthy and viable periodontal

ligament (PDL) cells on the root surface.11

Implants and removable or fixed partial den-

tures can also offer good alternatives, but

unlike natural teeth that have a normal PDL

and a natural esthetic, the use of artificial

material is a drawback.12 Autotransplants not

only maintain alveolar bone, they also trump

implants in that they allow proprioception

during function, and can be performed in

growing patients.13

The present case report presents a 40

year-old female. Teeth 53 and 63 have mo-

bility type II and impacted maxillary canines.

The treatment plan called for a series of

periodontal surgeries combined with ortho-

dontics and autotransplantation of teeth 13

and 23. The treatment lasted 1 year and

8 months, with the last clinical and radio-

graphic control carried out 4 years post-

treatment. The procedure described in this

article aimed to demonstrate that autotrans-

plantation is also a reliable alternative in cas-

es of impacted canines.

Case presentation

A 40-year-old female presented at the clinic

complaining of increased mobility in the

maxillary primary canines and of the un-

Introduction

According to clinical and radiographic as-

sessment, impacted teeth are described as

those that either erupt late or are not pre-

dicted to erupt completely. The incidence

of tooth impaction has been reported to

vary from 5.6% to 18.8% of the population.1

After the third molar, the second most fre-

quently impacted tooth is the permanent

maxillary canine, the impaction of which

has a prevalence of some 2% in the general

population.2 Of these, 85% are palatally im-

pacted, and 15% are labially impacted.3 The

maxillary canine performs a vital role in fa-

cial appearance, dental esthetics, lip sup-

port, arch development, functional occlu-

sion, and phonetics.4 In contrast, the

incidence of impacted mandibular canines

does not exceed 0.5%.5

The main treatment options available for

impacted canines include the wait-and-see

approach, interception, surgical exposure

(with or without orthodontic alignment), au-

totransplantation, and extraction. The two

most common methods used to bring pala-

tally impacted canines into occlusion con-

sist of: 1) surgically exposing the teeth and

allowing them to erupt naturally during early

or late mixed dentition; and 2) surgically ex-

posing the teeth and bonding an attach-

ment to move the tooth using orthodontic

forces.6,7

Orthodontic appliance treatment is some-

times hazardous or impractical, especially

when impacted maxillary canines are in

oblique/horizontal positions.8 Moreover, or-

thodontic treatment is not always accepted

by patients due to the 2- to 3-year treatment

time, and factors such as the position of the

canines as well as esthetic and economic

considerations. In such cases, if there is suffi-

cient space for the transplanted tooth, auto-

transplantation might provide a treatment al-

ternative.9 This process entails atraumatic

surgical removal of a tooth from its impacted

in the adjacent teeth (Fig 2a). It was decided

to perform cone beam computed tomogra-

phy (CBCT) to find out the exact position of

the permanent canines and to ascertain

whether autotransplantation of these teeth

was viable for replacing the primary canines.

After evaluating the different CBCT slices

(sagittal, coronal, and axial views), both ca-

nines were observed to be palatally placed,

making an autotransplantation technique

perfectly possible (Fig 2b to d). Due to the

patient’s age, and because orthodontic

treatment is prolonged, the surgical expo-

sure technique followed by orthodontic

traction was ruled out. The patient was fully

informed that in the event of autotransplan-

tation failure, the definitive treatment would

consist of either an implant or a fixed dental

prosthesis.

sightly aspect of her anterior teeth. At the

first appointment, the patient’s medical and

dental records showed no history of sys-

temic disease or drug allergies, and that she

was taking no medication. Clinical and ra-

diological testing to exclude pathological

processes revealed no contraindications for

dental treatment.

The pretreatment records showed nor-

mal vertical facial proportions, a straight

profile, and good facial symmetry. The initial

intraoral photograph confirmed that the

maxillary left and right primary canines were

retained and restored with composite resin

(Fig 1). Teeth 12 and 22 presented Miller

Class III gingival recessions, although anoth-

er clinician had previously attempted to cor-

rect them by performing two free epithelial

grafts. As seen in Figure 1, the result was un-

successful and unsightly. Analysis of the

dental casts disclosed a Class III molar rela-

tionship tendency on both sides. The maxil-

lary overjet was 2.0  mm and the overbite

4.0 mm, and the patient had no crossbites.

In addition, the upper midline shifted to the

left by 1 mm.

The panoramic radiograph showed that

both maxillary canines were impacted with-

out producing any apparent root resorption

formed gently with an excavator with the

aim of avoiding damage to the healthy PDL

remnants on the root (Fig 4d). When suffi-

cient bone was removed, the impacted ca-

nines were delicately elevated from their

sockets. Once the extractions had been

completed, the previously calculated digital

measurements (root length, total tooth

length, and diameter) were checked quickly

with a periodontal probe, and the teeth

were placed in saline solution until they

were transplanted. The curvature of the root

of the permanent canines meant that both

roots had to be shortened to better accom-

modate them in the recipient sites.

At this point, the work was divided into

two parts: one clinician prepared the new

sockets so that the teeth could be placed in

their correct anatomical position (Fig 5),

while another performed the endodontic

treatments and sealed the root-end cavities

with an apical plug using white root repair

material (ProRoot MTATT ; Dentsply Sirona) (Fig

6). Endodontic treatments and apical retro-

fillings were performed to avoid contamina-

tion of the bone substitute used to regener-

ate the cavities resulting from the extraction

of the canines. These cavities were suffi-

ciently large to facilitate the atraumatic ex-

traction of the impacted canines.

The recipient sites were modified by a

surgical implantology set (Camlog Biotech-

nologies). The entire milling sequence was

used up to the 6-mm-diameter drill, which

was moved from palatine to buccal with an

oscillating movement to form an ovoid re-

cipient capable of harboring the root of

both permanent canines. Care was taken to

preserve the entire buccal cortical plate.

The height of the palatal cortical plate was

preserved only in the area 2 mm coronal to

the right maxillary canine, and disappeared

completely during the site preparation to

house tooth 23. Given the amount of bone

removed in the palatal alveolar process, an

Treatment objectives

The objectives were to obtain root cover-

age of teeth 12 and 22 and replace the pri-

mary canines with the permanent ones by

means of autotransplant surgery. At the

same time, the esthetics of the anterior

teeth would be improved and the soft tissue

profile maintained.

Treatment progress

The first phase consisted of performing root

coverage surgery on teeth 12 and 22

through two connective tissue grafts (CTGs)

by means of a coronally advanced tunnel

flap (CATF) technique (Fig 3).AA After 3 months

of healing, multibracket orthodontic treat-

ment was started (Dolphin Aesthetic SLB

MBT 022; Ortolan) to align and level all the

teeth and to open up the space in the pri-

mary canine area (previously measured in

the CBCT) where the permanent canines

would be seated in an ideal 3D position (Fig

4a). The DICOM (Digital Imaging and Com-

munications in Medicine) files obtained

from the CBCT were used to measure the

length, height, and width of the permanent

canines. The distance between the trans-

planted canines and the neighboring teeth

was digitally calculated at about 2  mm to

provide sufficient space for the biologic

width and to achieve an optimum esthetic

outcome. The first phase of the orthodontic

treatment lasted 12 months.

After completing the first phase of the

treatment, autotransplantation surgery was

performed. First, the primary canines were

extracted carefully so as not to damage the

buccal cortical plate at any time (Fig 4b and

c). Bone covering the impacted teeth was

gradually demarcated using a piezoelectric

handpiece under abundant water-cooling

irrigation until a thin layer of bone was left

close to the cementum and enamel. Final

elevation of the bone as a block was per-

mucosa was placed. Then, a bioresorbable

membrane (OsteoBiol Evolution mem-

brane; Tecnoss) was inserted between the

bone substitute and the flap (Figs 7 and 8).

Before placing the permanent canines

on the modified recipient sites, they were

coated with enamel matrix proteins (Em-

dogain; Straumann), which facilitate the re-

generation of possible injured periodontal

tissue. At the same time, two new CTGs

were placed to stabilize the gingival margin

before the final suture. The upper archwire

system was maintained in order to passively

hold the permanent canines, which were

anchored to the arch by two brackets. The

canines were also splinted in the palatal sur-

face with a segment wire (0.012 nickel-tita-

nium) and composite resin for 30 days

(Fig 9a). In both canines, the time between

removal and placement of the impacted

tooth in the new socket did not exceed

25 min. In addition, to avoid canine-guided

occlusion during healing, occlusal lifts were

temporary placed on the maxillary incisors,

second premolars, and first molars (Fig 9b

and c).

After 1 month, new CTGs were per-

formed in both canine areas to finish re-

moving the epithelial remains from previous

surgeries (Figs 10 and 11). Advantage was

taken of these grafts to improve the bio-

types, stabilize the margins, and treat the

postsurgical residual recessions. The ortho-

connective grafts, the case was terminated

by performing an external bleaching as well

as direct composite restorations on teeth 12

and 22 to correct the wear and to shape the

anatomy of the teeth (Fig 12). The occlusion

was stabilized using a lingual bonded retain-

er (from teeth 33 to 43) and an upper Essix

retainer. The total treatment time was 1 year

and 8 months.

contour of the alveolar crest around teeth

with an open apex, are similar to those of

dental implants.13,19 When a donor tooth has

incompletely formed roots, pulp revascular-

ization allows for pulp healing and continual

root development. Thus, in most cases, no

endodontic treatment is required, allowing

for short treatment times, few pulpoperiapi-

cal problems, and almost no root frac-

tures.20 These advantages partly account for

the high success rates of autotransplants of

immature teeth, a procedure particularly in-

dicated in growing patients.21,22

Recent studies have also reported high

success rates in donor teeth with a closed

apex.11,23,24 In their meta-analysis of auto-

transplantation of maxillary canines, Grisar

et al15 showed an 87.5% outcome rate at 2 to

5 years follow-up, and 88.2% at over 5 years

follow-up. The pulp of a completely mature

tooth cannot generally regenerate. Hence,

if the tooth to be transplanted is accessible,

endodontic treatment should be completed

before transplantation;25 otherwise, the

endodontic treatment should be initiated

2 weeks after transplantation to avoid an in-

flammatory resorption from the infected

root canal.13 Endodontic treatment can also

be performed during the same surgical pro-

cedure (but was not done in this case) when

Discussion

The management of impacted canines is

important in terms of esthetics and func-

tion.14 Clinicians should plan treatments that

are in the best interests of the patient; there-

fore, they need to be knowledgeable about

the range of treatment options. Although

transplantation is not usually first-line treat-

ment for patients with impacted canines,

this procedure presents a mean survival of

14.5 years for 83% of transplants, making it a

viable option.8

Clinicians should take into account two

main factors when considering autotrans-

plantation for impacted maxillary canines: 1)

the anatomical complexity involved in ac-

commodating the canine with orthodontic

traction; and 2) the patient’s willingness to

wear orthodontic appliances or undergo

long-term treatment.15 Other factors to con-

sider include the available space in the arch

for autotransplantation, the prognosis of the

primary canines, the possibility of perform-

ing an atraumatic extraction while maintain-

ing the viability of the PDL, and the clini-

cian’s experience.16-18

totransplantation, particularly donor teeth

Despite the successful result of this case,

the autotransplantation technique may

present complications, such as root resorp-

tion and attachment loss, which could even

result in tooth loss, making the treatment

outcome difficult to predict.

Conclusions

Autotransplantation combined with ortho-

dontic treatment provides a viable treatment

alternative for impacted canines. The most

important factor for success is that a vital

(and functional) PDL must be attached to

the autotransplanted tooth. Necrosis or me-

chanical loss of the PDL leads to root re-

sorption (ankylosis or inflammatory resorp-

tion) or epithelial downgrowth. Even in

cases with extensive buccal or palatal/lin-

gual alveolar bone atrophy, promising and

optimally functional outcomes can be ob-

tained with the use of GBR. In this case,

modified surgical techniques allowed for a

minimally traumatic removal of the donor

teeth. Finally, it should be noted that CBCT

imaging is mandatory to develop a success-

ful treatment plan.

flicts of interest.

longer splinting periods are estimated. As

initial primary stability is crucial to the suc-

cess of autotransplantation,26 additional

damage to the PDL was avoided by per-

forming premature endodontic treatment.

The treatment was not postponed, which

would have jeopardized the success of the

guided bone regeneration (GBR) in an in-

fected root canal.

To increase the success rate of tooth au-

totransplantation and make it more predict-

able, it is necessary to be meticulous re-

garding the selection criteria, and to assess

in detail the viability of the donor tooth. In

this sense, low-dose CBCT is the more suit-

able technology for planning the surgical

feasibility and the optimal 3D position of the

donor tooth in the new socket.27,28 From the

CBCT files, computer-aided designed

3D-printed replicas of the donor tooth can

be obtained, although they were not used in

this case. Tooth replica acts as a surgical

guide; provides individualized bone adapt-

ability; and reduces extra-alveolar time for

the donor tooth, thus lowering the risk of

ankylosis.29,30

On the other hand, the treatment of gin-

gival recessions through plastic surgery pro-

cedures is both functionally and esthetically

essential, particularly in anterior teeth.31 The

main objective of these procedures is to

achieve complete root coverage, while im-

proving esthetics, hypersensitivity, and pre-

vention of caries and noncarious cervical

lesions. In this case, a series of periodontal

surgeries were performed, combined at dif-

ferent times with orthodontic treatment.

Various systematic reviews, including Cairo

et al32 and Sanz and Simion,33 have con-

firmed that the gold standard for root cover-

age consists of a coronally advanced flap

combined with a CTG. It has been shown

that the use of a CTG allows for a more sta-

ble coronal advance and less soft tissue

shrinkage. It also leads to increases in kerati-

nized tissue.34
