This case report describes the orthodontic treatment of a woman aged 15 years with permanent dentition brachyfacial typologywith congenitally missing maxillary lateral incisors Multibracket straightwire fixed appliance was used to open the space for dentalimplant placement and treat the impaired occlusion The missing lateral incisors were substituted with oral implants
1 Introduction
The management of missing lateral incisor requires an inte-grated multidisciplinary approach [1] Generally the choicebetween space opening with tooth replacement and spaceclosure with canine substitution relies on several parametersto be considered before treatment planning
Commonly the choice is related to occlusal relationship(ie overjet and overbite molar relationship) facial typologyand profile arch length and tooth size discrepancies Themorphology of the canine in terms of size and shape andits colour [2] also may address different treatment strategiesFinally patient expectation and compliance can influence thetreatment planning
In case of unilateral tooth agenesis space opening isoften recommended to improve the aesthetics of patients andpreserve smile symmetry On the contrary in case of bilateralagenesis space closure and space opening could be both per-formed with respect to the issues previously reported [3ndash6]
Space opening is advised in low-angle subjects whilst inhigh-angle individuals space closure should be preferred topreserve arch anchorage and avoid clock-wise rotation of thelower jaw Retruded profiles should be better treated withspace opening and tooth substitution in order to improvelabial sagittal relationships This treatment strategy should
be avoided in subjects with bimaxillary dental protrusion inwhich it could result in worsening of the profile
Molar relationship should be also considered Molarclass I or class III tendency should be better treated withspace opening to preserve ideal occlusal anterior andposterior relationship (ie canine and molar relationship)and establish a solid angle class I In case of full cusp orpartial molar class II space closure should be preferred tofacilitate orthodontic biomechanics and reduce treatmentduration A stable molar class II and canine class I are thenobtained However in case of arch length discrepanciesextractions in the lower arch should be considered thusobtaining a molar and canine class I
Anterior relationship that is overjet and overbite mustbe taken into account in terms of facilitation of biome-chanics Reduced overjet and increased overbite may easilybe improved by space opening mechanics whilst increasedoverjet and reduced overbite may benefit from space closure
Shape and size of canines affect the possible rehabilitationchoice Differently from cases with large canines in whichspace opening is advocated small canines can be easilytransformed in lateral incisors by using porcelain veneersor composite materials The original position of the canineshould be considered Teeth closer to the midline are bestcandidate for incisor substitution

The patient was 15 years old She presented this objectiveproblem list
(i) missing maxillary lateral incisors(ii) class I malocclusion(iii) presence of the deciduous maxillary right canine(iv) spacings in the left side(v) brachyfacial typology and retruded profile(vi) slight arch length discrepancies(vii) maxillary permanent canines close to midline(viii) slight deviation of the upper midline
She sustained a whiplash injury at the age of thirteendue to a car accident but she did not present signs orsymptoms of temporomandibular disorders according toResearch Diagnostic Criteria for Temporomandibular Disor-ders (RDCTMD) [7 8] Oral parafuctions such as clenchingwere present and taken into account because of a possiblerelation with muscle pain [9]
The cephalometric evaluation highlighted a brachifa-cial typology with a sagittal skeletal relationship of class I(Figure 3) The patient reported to have been treated at theage of 10 with a functional appliance (Sander Bite JumpingAppliance) to correct a skeletal class II malocclusion [10]
The treatment plan included the space opening ofmissinglateral incisors for implant placement and correcting herocclusion
A fixed multibracket appliance was placed to alignlevel and manage spacings of both upper and lowerdental arches Thermal Ni-Ti archwires were preferred toincrease patient compliance and reduce initial discomfort[11] The biomechanics and the progressive opening ofthe space for the maxillary lateral incisors are showed inFigure 4
Initially a 03610158401015840 stainless steel transpalatal arch wasmodelled to correct molar rotations and to obtain additionalanchorage Later compressed springs were applied to thisappliance to obtain further proclination of the upper incisors[12]
Alignment of both dental arches was achieved by usingmultibracket appliance (Roth prescription slot size 02210158401015840times02810158401015840 with heat activated Ni-Ti archwires (round 01410158401015840 andround 01610158401015840) Transbond XT (3M Unitek Monrovia US)adhesive primer was used for its strength [13] following theinstructions of the manufacturer
After aligning the cuspids distalization was obtained byusing interarches and intra-arch elastics on a round 01810158401015840AJ Wilcock Australian wire (regular + GampH OrthodonticsFranklin IN US) The anchorage was preserved by plac-ing the elastics between upper molars and canines duringdaytime and between lower molars and upper canines atnighttime This pattern was easily accepted by the patientsbecause during daytime the elastics were not visible Supere-lastic coil springs for gaining space for maxillary lateralincisors were avoided in order to preserve the initialoverjet
The distalization of the canines resulted in a slightdistopalatal rotation and a distal tip of the crowns Thedistopalatal rotations were corrected by using a 01910158401015840 times 02510158401015840TMA sectional determining Burstonersquos 6th Geometry [14] sothat an ideal rotational effect was obtainedwithout horizontalundesirable movements To further obtain root uprightingand achieve an ideal placement of the roots for a propersite for implant rehabilitation two cantilevers were used andapplied to the central incisors segment This allowed also fora better control of the overbite The correction of midlinediscrepancy was mainly obtained by using a stainless steel02110158401015840 times 02510158401015840 power arm positioned on the central incisorsand shaped so that the force was applied close to the centerof resistance of both teeth This was finally attached withan elastomeric ligature to a TMA 01910158401015840 times 02510158401015840 cantileverinserted in the auxiliary buccal gingival tube of the band ofthe first left maxillary molar
The anchorage for proper biomechanics was obtained byusing full size stainless steel wires and a passive transpalatalarch
The treatment lasted approximately thirtymonthsThere-after the patient was referred to the oral surgeon for the posit-ing of the implants The intraoral and extraoral photographsat the end of orthodontic treatment are presented in Figures5ndash7
Bone grafts from the extraction site of the lower leftwisdom tooth were inserted by piezoelectric surgery in themaxillary lateral incisors sites The grafts were fixed by usingosteosynthesis screws in the implant sites and covered byabsorbable membranes

Figure 3 Cephalometric values and panoramic radiograph at thestart of treatment From left to right value measured average valuefrom the population norm standard deviation of the average valuefrom the population norm and difference from the extreme valueof the population norm Blue values above the norm green valuesbelow the norm black values within the norm
The patient was 15 years old She presented this objectiveproblem list
(i) missing maxillary lateral incisors(ii) class I malocclusion(iii) presence of the deciduous maxillary right canine(iv) spacings in the left side(v) brachyfacial typology and retruded profile(vi) slight arch length discrepancies(vii) maxillary permanent canines close to midline(viii) slight deviation of the upper midline
She sustained a whiplash injury at the age of thirteendue to a car accident but she did not present signs orsymptoms of temporomandibular disorders according toResearch Diagnostic Criteria for Temporomandibular Disor-ders (RDCTMD) [7 8] Oral parafuctions such as clenchingwere present and taken into account because of a possiblerelation with muscle pain [9]
The cephalometric evaluation highlighted a brachifa-cial typology with a sagittal skeletal relationship of class I(Figure 3) The patient reported to have been treated at theage of 10 with a functional appliance (Sander Bite JumpingAppliance) to correct a skeletal class II malocclusion [10]
The treatment plan included the space opening ofmissinglateral incisors for implant placement and correcting herocclusion
A fixed multibracket appliance was placed to alignlevel and manage spacings of both upper and lowerdental arches Thermal Ni-Ti archwires were preferred toincrease patient compliance and reduce initial discomfort[11] The biomechanics and the progressive opening ofthe space for the maxillary lateral incisors are showed inFigure 4
Initially a 03610158401015840 stainless steel transpalatal arch wasmodelled to correct molar rotations and to obtain additionalanchorage Later compressed springs were applied to thisappliance to obtain further proclination of the upper incisors[12]
Alignment of both dental arches was achieved by usingmultibracket appliance (Roth prescription slot size 02210158401015840times02810158401015840 with heat activated Ni-Ti archwires (round 01410158401015840 andround 01610158401015840) Transbond XT (3M Unitek Monrovia US)adhesive primer was used for its strength [13] following theinstructions of the manufacturer
After aligning the cuspids distalization was obtained byusing interarches and intra-arch elastics on a round 01810158401015840AJ Wilcock Australian wire (regular + GampH OrthodonticsFranklin IN US) The anchorage was preserved by plac-ing the elastics between upper molars and canines duringdaytime and between lower molars and upper canines atnighttime This pattern was easily accepted by the patientsbecause during daytime the elastics were not visible Supere-lastic coil springs for gaining space for maxillary lateralincisors were avoided in order to preserve the initialoverjet
The distalization of the canines resulted in a slightdistopalatal rotation and a distal tip of the crowns Thedistopalatal rotations were corrected by using a 01910158401015840 times 02510158401015840TMA sectional determining Burstonersquos 6th Geometry [14] sothat an ideal rotational effect was obtainedwithout horizontalundesirable movements To further obtain root uprightingand achieve an ideal placement of the roots for a propersite for implant rehabilitation two cantilevers were used andapplied to the central incisors segment This allowed also fora better control of the overbite The correction of midlinediscrepancy was mainly obtained by using a stainless steel02110158401015840 times 02510158401015840 power arm positioned on the central incisorsand shaped so that the force was applied close to the centerof resistance of both teeth This was finally attached withan elastomeric ligature to a TMA 01910158401015840 times 02510158401015840 cantileverinserted in the auxiliary buccal gingival tube of the band ofthe first left maxillary molar
The anchorage for proper biomechanics was obtained byusing full size stainless steel wires and a passive transpalatalarch
The treatment lasted approximately thirtymonthsThere-after the patient was referred to the oral surgeon for the posit-ing of the implants The intraoral and extraoral photographsat the end of orthodontic treatment are presented in Figures5ndash7
Bone grafts from the extraction site of the lower leftwisdom tooth were inserted by piezoelectric surgery in themaxillary lateral incisors sites The grafts were fixed by usingosteosynthesis screws in the implant sites and covered byabsorbable membranes

Case Reports in Dentistry 7
shows a good radicular parallelism and no signs of rootresorption (Figures 6 7 and 8) The clinical examination ofthe masticatory muscles and temporomandibular joints didnot show any pathological signs or symptoms at completionof treatment
The cantilever mechanics [15] allowed a correct reposi-tioning of the roots of the maxillary incisors
Conventional brackets were used because it has beensuggested that self-ligating brackets are critical for obtainingan adequate torque control [16] Also we used heat activatedNi-Ti archwires to reduce patient discomfort [11]
The results achieved were maintained during the reten-tion period by means of a fixed lingual 33ndash43 retainer Theresults achieved were substantially maintained at posttreat-ment control Occlusal relationship and dental alignmentwere stable

shows a good radicular parallelism and no signs of rootresorption (Figures 6 7 and 8) The clinical examination ofthe masticatory muscles and temporomandibular joints didnot show any pathological signs or symptoms at completionof treatment
The cantilever mechanics [15] allowed a correct reposi-tioning of the roots of the maxillary incisors
Conventional brackets were used because it has beensuggested that self-ligating brackets are critical for obtainingan adequate torque control [16] Also we used heat activatedNi-Ti archwires to reduce patient discomfort [11]
The results achieved were maintained during the reten-tion period by means of a fixed lingual 33ndash43 retainer Theresults achieved were substantially maintained at posttreat-ment control Occlusal relationship and dental alignmentwere stable
