ABSTRACT
The aim of this review was to investigate usage of computer‑aided design/computer‑aided manufacture (CAD/CAM) such
as milling and rapid prototyping (RP) technologies for removable denture fabrication. An electronic search was conducted
in the PubMed/MEDLINE, ScienceDirect, Google Scholar, and Web of Science databases. Databases were searched from
1987 to 2014. The search was performed using a variety of keywords including CAD/CAM, complete/partial dentures, RP,
rapid manufacturing, digitally designed, milled, computerized, and machined. The identied developments (in chronological
order), techniques, advantages, and disadvantages of CAD/CAM and RP for removable denture fabrication are summarized.
Using a variety of keywords and aiming to nd the topic, 78 publications were initially searched. For the main topic, the
abstract of these 78 articles were scanned, and 52 publications were selected for reading in detail. Full‑text of these articles
was gained and searched in detail. Totally, 40 articles that discussed the techniques, advantages, and disadvantages of CAD/
CAM and RP for removable denture fabrication and the articles were incorporated in this review. Totally, 16 of the papers
summarized in the table. Following review of all relevant publications, it can be concluded that current innovations and
technological developments of CAD/CAM and RP allow the digitally planning and manufacturing of removable dentures
from start to nish. As a result according to the literature review CAD/CAM techniques and supportive maxillomandibular
relationship transfer devices are growing fast. In the close future, fabricating removable dentures will become medical
informatics instead of needing a technical staff and procedures. However the methods have several limitations for now.
Key words: Computer-aided design/computer-aided manufacture, rapid prototyping, removable partial denture

automatically physical models from computerized
three‑dimensional (3D) data.[2,3] RP, also known as
solid freeform fabrication or layered manufacturing,
has been used for creating 3D complex models in the
eld of medicine since the 1990s and has recently
become popular for the fabrication of removable
dental prostheses.[4,5] CAD/CAM and RP have
been used for several years for the fabrication
of inlays, onlays, crowns, fixed partial dentures,
implant abutments/prostheses, and maxillofacial
prostheses.[6] Currently, not only xed restorations
but also removable dentures are manufactured
using CAD/CAM and RP.[7‑14] However, few studies
have reported on the use and effectiveness of RP for
removable denture fabrication.[4]
Subtractive manufacturing technique is based on
milling the product from a block by a CNC machine.
The CAM software automatically transfers the CAD
model into tool path for the CNC machine. This
involves computation that points the CNC milling,
including sequencing, milling tools, and tool motion
direction and magnitude. Due to the anatomical
variances of dental restoration, the milling machines
combine burs with different sizes. The accuracy of
milling is shown to be within 10 µm.[15,16]
The rst removable prosthesis based on 3D laser
lithography was manufactured by Maeda et al.[12] in 1994.
Subsequently, the removable prosthesis duplication
technique was improved using CAD/CAM with a
computerized numerical control (CNC) system and
ball‑end mills by Kawahata et al.[11] in 1997. Then, Sun
et al.[13] fabricated individual physical asks using a
3D printer.
Impressions of the edentulous maxilla and mandible
or existing dentures are subjected to laser scanning
during CAD.[11,12] Also, cone beam computed
tomography is used for the modication of previous
dentures.[7] CNC, laser lithography, and RP are used
for the CAM process.[10‑13]
AvaDent and Dentca are the two available commercial
manufacturers of removable complete dentures
with CAD/CAM, using a gadget for transferring
the maxillomandibular relation (MMR) to a digital
articulator and nalizing the dentures completely
with CAD/CAM. In the process used by AvaDent,
denture bases are milled using a subtractive technique
from prepolymerized denture resin. The Dentca
technique uses an additive process, wherein a trial
denture can be prepared, if the dentist requires, using
RP (stereolithography [SLA]) before the conventional
fabrication of a denitive prosthesis.[17‑19]

A digital model of the RPD framework was designed, and its sacricial model was fabricated
using RP. Then, the alloy framework was processed using the cast mold method
Kanazawa et al.[7] Milling Kanazawa et al. used CBCT scans of prostheses and denture teeth and digitally arranged
the teeth. The prosthesis base was fabricated from a block of acrylic resin using CNC milling,
following which the teeth were manually bonded in the holes created in the denture base
Jevremović et al.[24] Rapid prototyping Jevremović et al. studied about alloys used for fabricating prostheses using
SLM. They concluded that Co-Cr alloys did not have cytotoxic effects, while
some metals commonly resulted in side effects, mentioning that 30 alloys
showed similar characteristics used in SLM for cast alloy processing
Goodacre et al.[9] Milling Goodacre et al. scanned silicone impressions by neutral zone technique for scanning,
additionally recorded interocclusal relations, then teeth were arranged digitally. The

Inokoshi et al.[10] Rapid prototyping Inokoshi et al. scanned wax trial prostheses of 10 patients using CBCT and modied
the scanned digital prostheses using computer software. Seven prototypes were
fabricated using RP, with various modications in teeth arrangements for researching
the applicability of prototype prostheses for trial placement functions
Alifui-Segbaya
et al.[25]
Rapid prototyping They researched the effects of the corrosive function of articial saliva on cast and Co‑Cr
alloys manufactured using RP. They found that some dental alloys, including Co, Cr, and
molybdenum, can be used in the oral cavity because of their acceptable ion release levels
Yoon et al.[26] Milling The research group had tried a different approach for restoring worn articial teeth

machining used for the manufacture of crowns,
posts, inlays, and onlays. The subtractive production
methods include spark erosion and milling. The spark
erosion can be dened as a metal substractive process
using continuing sparks to erode material from a
metal block according to the CAD under required
conditions. Milling techniques are diamond grinding
and carbide milling which are now found together in
chairside and inLab CAD/CAM devices together and
as the latest transferred technology from manufacture
industry to dental use is laser milling, which was
announced in rst quarter of 2015. Milling techniques
are mostly dependent on the device properties such as
the dimensional approach and possibilities of working
axis: 3 spatial direction X, Y, and Z which refers to 3
axis milling devices while 3 spatial direction X, Y, Z
and tension bridge refers to 4 axis milling device, and
nally 3 spatial direction X, Y, Z, tension bridge with
milling spindle is classied as 5 axis milling device.[30]
Additive 3D printing techniques include SLA, digital
light projection (DLP), jet (PolyJet/ProJet) printing,
and direct laser metal sintering (DLMS)/selective
laser sintering (SLS).
The SLA technique uses ultraviolet (UV) laser for
layer‑by‑layer polymerization of materials. The
technique is used for the manufacture of dental
models from UV‑sensitive liquid resins. DLP uses UV
laser and visible light for polymerization and is used
for the manufacture of dental models, wax patterns,
removable partial frameworks, and provisional
restorations from visible light‑sensitive resins, wax,
and composite materials. After the material is printed,
it is cured using a light‑emitting diode light source
or lamp.[31] Also, polymethyl methacrylate (PMMA)
is used in the DLP technique.[32] Jet (PolyJet/ProJet)
printing uses a series of ink‑jet print heads and
tiny pieces of material jetted onto support material
and create each layer of the part. Then, each jetted
layer is hardened using a UV lamp, light source, or
heating. This technique is used for the manufacture
of dental models, surgical drill guides, aligners, wax
patterns, and removable frameworks from dental
resin and waxes. DLMS/SLS is a powder‑based
technique wherein high‑power laser beam hits the
powder, resulting in melt and fusion of the powder
particles. This technique is used for the manufacture
of dental models, copings, and surgical guides from
cobalt‑chrome, palladium chrome, and nylon.[31]

Manufacturing steps for complete dentures
First, models can be prepared using conventional
impression or intraoral digital impression. When
digital impression is considered, practitioner will

and multifunctional device which has driven the

development of 3D imaging.[33] The precision of digital
impression has been studied by several researchers and
found out that use of digital models is a relatively new
technique that has an accuracy of up to 10 µm, and the
models have been found to be as reliable as traditional
stone casts.[34] Nalcaci et al.[35] found out statistically
significant differences between measurements
obtained for width of 6 anterior teeth and 12 overall
teeth using plaster and digital models; however, these
differences were not within the clinically signicant
range (~0.27–0.30 mm). Therefore, casts are scanned
using digital scanner for conventional technique.
After taking impression, the next step is making
MMR transfer during complete prosthesis fabrication
using CAD/CAM. There are three options for MMR
transfer during complete prosthesis fabrication using
CAD/CAM: The MMR can be transferred using
conventional impression and transfer techniques,
the AvaDent system kit, or the Dentca system kit.[18,19]
Two clinical appointments are required for the
manufacture of removable complete dentures using the
Avadent and Dentca systems. In the rst appointment,
impressions are recorded using special trays provided
in the AvaDent or Dentca system. Then, the jaw relation
is recorded using an anatomical measuring device.
The occlusal vertical dimension (OVD) is determined
using conventional methods. Subsequently, the centric
relation is recorded, and teeth are selected. The last
step of the rst appointment is the delivery of the nal
impression to the manufacturer (AvaDent or Dentca).
At the laboratory, the denture borders are rst dened
and marked using the system’s computer software.
Then, the teeth are virtually set, and the prosthesis
base is milled from traditional denture resin material.
A trial denture can be prepared as per the dentist’s
request.
In the second clinical appointment, the dentures are
delivered and any occlusal adjustments made. These
steps are similar to those for conventional prosthesis
delivery. Only the AvaDent technique of denture base
manufacture is not conventional.[17‑19]
Manufacturing steps for framework of partial
prosthesis
Designing of the RPD framework generally consists
of four parts as base, plate, clasp, major, and minor
connector of the framework. Every part of the RPD
framework must be done proper design and thick
value in the designing process.[23] Because of the
variety of RPD parts and their irregular forms, 3D
designing of RPD framework is taking much time and
complicated. For this reason, researchers investigated
proper CAD/CAM method and software for 3D
designing of RPD framework for many years.[20,21,36,37]
Basically, steps for manufacturing of framework
of partial prosthesis with CAD/CAM and RP are:
First, dental casts are prepared using conventional
impression method or digital impression. Casts
are scanned using digital scanner for conventional
technique. Path of insertion of the RPD is dened
digitally, and then shape of the components of the
framework is designed 3D by dentists or laboratory
technicians. Finally, digitally designed metal RPD
frameworks are produced with RP.[36]
Advantages of digital fabrication of dentures
• Decreased number of appointments
• Shrinkage of acrylic base caused by milling of
prepolymerized acrylic resin with an increase in
the strength and t of dentures
• Decreased duration of prosthesis manipulation
• Decrease in the risk of microorganism colonization
on the denture surfaces and consequent infection
• Advances in standardization for clinical research
on removable prostheses
• Easy reproduction of the denture and manufacture
of a trial denture using stored digital data
• Superior quality control by clinicians and
technicians.[38]
Limitations and disadvantages of digital fabrication
of dentures
• Manufacturing challenge caused by
impression‑taking and OVD‑recording procedures,
MMR transfer, and maintenance of lip support,
which are all similar to the procedures used in the
conventional process
• Inability to dene the mandibular occlusal plane
• Expensive materials and increased laboratory cost
compared with those for conventional methods
• Lack of trial denture manufacture by the Avadent
system,[18] which precludes the evaluation of
dentures by patients and dentists before final
denture fabrication.
CONCLUSIONS
Since the fabrication of the rst modern removable
dentures using PMMA, no significant changes in
fabricating techniques were introduced until
CAD/CAM techniques came into the picture in the
1990s. Current innovations and developments in

dental technology allow the fabrication of removal
dentures using CAD/CAM technologies from start
to nish, thus decreasing the chair side and working
time for patients and dentists and providing superior
or satisfactory functional and esthetic outcomes. The
development of a digital face simulator using imaging
techniques with lower effective doses of radiation in
the close future will be another milestone for removable
denture fabrication with digital OVD recording and
MMR transfer before nalization with CAM.
