O que é CDT?
É um manual de referência Internacional publicado anualmente pela ADA (American Dental Association) e contém o Código de Procedimentos e Nomenclatura Dentária (Código CDT). (válido apenas para o EUA).
O Código CDT é um conjunto de códigos processuais para saúde bucal e serviços auxiliares prestados em odontologia. Cada código processual consiste em um caractere alfanumérico começando com a letra “D” (o código do procedimento) e um título (a nomenclatura). Inclui também narrativas escritas (descritores) para alguns dos códigos processuais. O Código CDT categoriza códigos por
tipo de serviço: diagnóstico, preventivo, restaurador, endodontia, periodontia, prótese removível, próteses maxilofaciais, serviços de implantes, prótese fixa, oral e maxilofacial cirurgia, ortodontia e serviços gerais adjuntos. Contudo, nada no CDT suporta ou indica limitação de uso por dentistas - dentistas gerais ou especialistas - a qualquer categoria seção (s) do Código CDT.

CDT Code Description
CDT D5913
Nasal prosthesis
[Synonymous terminology: artificial nose; A removable prosthesis attached to the
skin, which artificially restores part or all of the nose. Fabrication of a nasal
prosthesis requires creation of an original mold. Additional prostheses usually can be
made from the same mold, and assuming no further tissue changes occur, the same
mold can be utilized for extended periods of time. When a new prosthesis is made
from the existing mold, this procedure is termed a nasal prosthesis replacement].
CDT D5914
Auricular prosthesis
[Synonymous terminology: artificial ear, ear prosthesis; A removable prosthesis,
which artificially restore part of all of the natural ear. Usually, replacement prosthesis
can be made from the original mold if tissue bed changes have not occurred.
Creation of an auricular prosthesis requires fabrication of a mold, from which
additional prostheses usually can be made, as needed later (auricular prosthesis,
replacement)].
CDT D5915
Orbital prosthesis
[A prosthesis, which artificially restores the eye, eyelids, and adjacent hard and soft
tissue, lost as a result of trauma or surgery. Fabrication of an orbital prosthesis
requires creation of an original mold. Additional prostheses usually can be made from
the same mold, and assuming no further tissue changes occur, the same mold can be
utilized for extended periods of time. When a new prosthesis is made from the
existing mold, this procedure is termed an orbital prosthesis replacement].
CDT D5916
Ocular prosthesis
[Synonymous terminology: artificial eye, glass eye; A prosthesis, which artificially
replaces an eye missing as a result of trauma, surgery or congenital absence. The
prosthesis does not replace missing eyelids or adjacent skin, mucosa or muscle;
Ocular prosthesis require semiannual or annual cleaning and polishing. Also,
occasional revisions to re-adapt the prosthesis to the tissue bed may be necessary.
Glass eyes are rarely made and cannot be re-adapted].
CDT D5919
Facial prosthesis
[Synonymous terminology: prosthetic dressing; A removable prosthesis, which
artificially replaces a portion of the face, lost due to surgery, trauma or congenital
absence. Flexion of natural tissues may preclude adaption and movement of the
prosthesis to match the adjacent skin. Salivary leakage, when communicating with
the oral cavity, adversely affects retention].
CDT D5922
Nasal septal prosthesis
[Synonymous terminology: Septal plug, septal button; Removable prosthesis to
occlude (obdurate) a hole within the nasal septal wall. Adverse chemical degradation
in this moist environment may require frequent replacement. Silicone prostheses are
occasionally subject to fungal invasion].
CDT D5923
Ocular prosthesis, interim
[Synonymous terminology: Eye shell, shell, ocular conformer, conformer.
A temporary replacement generally made of clear acrylic resin for an eye lost due to
surgery or trauma. No attempt is made to re-establish esthetics. Fabrication of an
interim ocular prosthesis generally implies subsequent fabrication of an aesthetic
ocular prosthesis].
CDT D5924
Cranial prosthesis
[Synonymous terminology: Skull plate, cranioplasty prosthesis, cranial implant. A
biocompatible, permanently implanted replacement of a portion of the skull bones;
an artificial replacement for a portion of the skull bone].
CDT D5925
Facial augmentation implant prosthesis
[Synonymous terminology: facial implant. An implantable biocompatible material
generally onlayed upon an existing bony area beneath the skin tissue to fill in or
collectively raise portions of the overlaying facial skin tissues to create acceptable
contours].

CDT Code Description
CDT D5926
Nasal prosthesis, replacement
[Synonymous terminology: replacement nose. An artificial nose produced from a
previously made mold. A replacement prosthesis does not require fabrication of a
new mold. Generally, several prostheses can be made from the same mold assuming
no changes occur in the tissue bed due to surgery or age related topographical
variations].
CDT D5927
Auricular prosthesis, replacement
[Synonymous terminology: replacement ear. An artificial ear produced from a
previously made mold. A replacement prosthesis does not require fabrication of a
new mold. Generally, several prostheses can be made from the same mold assuming
no changes occur in the tissue bed due to surgery or age related topographical
variations].
CDT D5928
Orbital prosthesis, replacement
[A replacement for a previously made orbital prosthesis. A replacement prosthesis
CDT Does not require fabrication of a new mold. Generally, several prostheses can be
made from the same mold assuming no changes occur in the tissue bed due to
surgery or age related topographical variations].
CDT D5929
Facial prosthesis, replacement
[A replacement facial prosthesis made from original mold. A replacement prosthesis
CDT Does not require fabrication of a new mold. Generally, several prostheses can be
made from the same mold assuming no changes occur in the tissue bed due to
surgery or age related topographical variations].
CDT D5931
Obturator prosthesis, surgical
[Synonymous terminology: Obturator, surgical stayplate, immediate temporary
obturator.
A temporary prosthesis inserted during or immediately following surgical or traumatic
loss of a portion or all of one or both maxillary bones and contiguous alveolar
structures (e.g., gingival tissue, teeth). Frequent revisions of surgical obturators are
necessary during the ensuing healing phase (approximately six months). Some
CDT Dentist prefer to replace many or all teeth removed by the surgical procedure in the
surgical obturator while other do not replace any teeth. Further surgical revisions
may require fabrication of another surgical obturator (e.g., an initially planned small
CDT Defect may be revised and greatly enlarged after the final pathology report indicates
margins are not fee of tumor)].
CDT D5932
Obturator prosthesis, definitive
[Synonymous terminology: obturator. A prosthesis, which artificially replaces part or
all of the maxilla and associated teeth, lost due to surgery, trauma or congenital
CDT Defects. A definitive obturator is made when it is deemed that further tissue changes
or recurrence of tumor are unlikely and a more permanent prosthetic rehabilitation
can be achieved; it is intended for long-term use].
CDT D5933
Obturator prosthesis, modification
[Synonymous terminology: adjustment, denture adjustment, temporary or office
reline.
Revision or alteration of an existing obturator (surgical, interim, or definitive);
possible modifications include relief of the denture base due to tissue compression,
augmentation of the seal or peripheral areas to effect adequate sealing or separation
between the nasal and oral cavities].
CDT D5934
Mandibular resection prosthesis with guide flange
[Synonymous terminology: resection device, resection appliance. A prosthesis which
guides the remaining portion of the mandible, left after a partial resection, into a
more normal relationship with the maxilla. This allows for some tooth-to-tooth or an
improved tooth contact. It may also artificially replace missing teeth and thereby
increase masticatory efficiency].
CDT Dental Services: CDT Codes Page 4 of 29

CDT Code Description
CDT D5935
Mandibular resection prostheis without guide flange
[A prosthesis which helps guide the partially resected mandible to more normal
relation with the maxilla allowing for increased tooth contract. It does not have a
flange or ramp, however, to assist in directional closure. It may replace missing teeth
and thereby increase masticatory efficiency. Dentists who treat mandibulectomy
patients may refer to replace some, all or none of the teeth in the defect area.
Frequently, the defect’s margins preclude even partial replacement. Use of a guide (a
mandibular resection prosthesis with a guide flange) may not be possible due to
anatomical limitation or poor patient tolerance. Ramps, extended occulsal
arrangements and irregular occlusal positioning relative to the denture foundation
frequently preclude stability of the prostheses, and thus some prostheses are poorly
tolerated under such adverse circumstances].
CDT D5936
Obturator prosthesis, interim
[Synonymous terminology: immediate post-operative obturator. A prosthesis which is
made following completion of the initial healing after a surgical resection of a portion
or all of one or both the maxillae; frequently many or all teeth in the defect area are
replaced by this prosthesis. This prosthesis replaces the surgical obturator, which is
usually inserted at, or immediately following the resection.
Generally, in interim obturator is made to facilitate closure of the resultant defect
after initial healing has been completed. Unlike the surgical obturator, which usually
is made prior to surgery and frequently revised in the operating room during surgery,
the interim obturator is made when the defect margins are clearly defined and
further surgical revisions are not planned. It is a provisional prosthesis, which may
replace some or all lost teeth, and other lost bone and soft tissue structures. Also, it
frequently must be revised (termed an obturator prosthesis modification) during
subsequent dental procedures (e.g., restorations, gingival surgery) as well as to
compensate for further tissue shrinkage before a definitive obturator prosthesis is
made].
CDT D5937
Trismus appliance (not for TMD treatment)
[Synonymous terminology: occlusal device for mandibular trismus, dynamic bite
opener. A prosthesis, which assists the patient in increasing their oral aperture width
in order to eat as well as maintain oral hygiene. Several version and designs are
possible, all intending to ease the sever lack of oral opening experienced by many
patient immediately following extensive intraoral surgical procedure].
CDT D5952
Speech aid prosthesis, pediatric
[Synonymous terminology: nasopharyngeal obturator, speech appliance, obturator,
cleft palate appliance, prosthetic speech aid, speech bulb. A temporary or interim
prosthesis used to close a defect in the hard and/or soft palate. It may replace tissue
lost due to developmental or surgical alterations. It is necessary for the production of
intelligible speech. Normal lateral growth of the palatal bones necessitates occasional
replacement of this prosthesis. Intermittent revisions of the obturator section can
assist in maintenance of the palatalpharyngeal closure (termed a speech aid
prosthesis modification). Frequently, such prostheses are not fabricated before the
CDT Deciduous dentition is fully erupted since clasp retention is often essential]
CDT D5953
Speech aid prosthesis, adult
[Synonymous terminology: prosthetic speech appliance, speech aid, speech bulb. A
CDT Definitive prosthesis, which can improve speech in adult cleft palate patients either by
obturating (sealing off) a palatal cleft or fistula, or occasionally by assisting an
incompetent soft palate. Both mechanisms are necessary to achieve velopharyngeal
competency.
Generally, this prosthesis is fabricated when no further growth is anticipated and the
objective is to achieve long-term use. Hence, more precise materials and techniques
are utilized. Occasionally such procedures are accomplished in conjunction with
precision attachments in crown work undertaken on some or all maxillary teeth to
achieve improved aesthetics].
CDT D5954
Palatal augmentation prosthesis
[Synonymous terminology: superimposed prosthesis, maxillary glossectomy
prosthesis, maxillary speech prosthesis, palatal drop prosthesis. A removable
prosthesis which alters the hard and/or soft tissue palate’s topographical form
adjacent to the tongue].

CDT Code Description
CDT D5955
Palatal lift prosthesis, definitive
[A prosthesis which elevates the soft palate superiorly and aids in restoration of soft
palate functions which may be lost due to an acquired, congenital or developmental
CDT Defect. A definitive palatal lift is usually made for patients whose experience with an
interim palatal lift has been successful, especially if surgical alterations are deemed
unwarranted].
CDT D5958
Palatal lift prosthesis, interim
[Synonymous terminology: diagnostic palatal lift; A prosthesis which elevates and
assists in restoring soft palate function which may be lost due to clefting, surgery,
trauma or unknown paralysis. It is intended for interim use to determine its
usefulness in achieving palatapharyngeal competency or enhance swallowing
reflexes. This prosthesis is intended for interim use as diagnostic aid to asses the
level of possible improvement in speech intelligibility. Some clinicians believe use of a
palatal lift on an interim basis may stimulate an otherwise flaccid soft palate to
increase functional activity, subsequently lessening its need].
CDT D5959
Palatal lift prosthesis, modification
[Synonymous terminology: revision of lift, adjustment. Alterations in the adaptation,
contour, form or function of an existing palatal lift necessitated due to tissue
impingement, lack of function, poor clasp adaptation or the like].
CDT D5960
Speech aid prosthesis, modification
[Synonymous terminology: adjustment, repair, revision.
Any revision of a pediatric or adult speech aid not necessitating its replacement.
Frequently, revisions of the obturating sections of any speech aid are required to
facilitate enhanced speech intelligibility. Such revisions or repairs do not require
complete remaking of the prosthesis, thus extending its longevity].
CDT D5982
Surgical stent
[Synonymous terminology: periodontal stent, skin graft stent, columellar stent.
Stents are utilized to apply pressure to soft tissue to facilitate healing and prevent
cicatrization of collapse. A surgical stent maybe required in surgical and post-surgical
revisions to achieve close approximation of tissues. Usually such materials as
temporary or interim soft denture liners, gutta percha, or dental modeling impression
compound may be used].
CDT D5988
Surgical splint
[Synonymous terminology: Gunning splint, modified Gunning splint, labiolingual
splint, fenestrated splint, Kingsley splint, cast metal splint; Splints are designed to
utilize existing teeth and/or alveolar processes as points of anchorage to assist in
stabilization and immobilization of broken bones during healing. They are used to reestablish, as much as possible, normal occlusal relationships during the process of
immobilization. Frequently, existing prostheses (e.g., a patient’s complete dentures)
can be modified to serve as surgical splints. Frequently, surgical splint have arch bars
added to facilitate intermaxillary fixation. Rubber elastics may be used to assist in
this process. Circummandubular eyelet hooks can be utilized for enhanced
stabilization with wiring to adjacent bone].
