LEARNING OBJECTIVES

The overall goal of this course is to provide information on the digital workfl ow for implant therapy. After completing this course, participants will be able to:

1. Describe key factors in implant treatment planning;

2. Review the digital workfl ow and the use of digital setups in implant treatment planning;

3. Outline implant components that can be viewed virtually; and,

4. Describe CAD/CAM digital technology as part of the digital workfl ow and its use for printed and milled components used during implant therapy.

Implant treatment is a reliable treatment that is increasingly in demand for the replacement of missing teeth. During implant treatment planning, anatomical structures must be accurately identifi ed and treatment must be planned from the perspective of the desired restorative result. This is of particular importance in the anterior region, where esthetics is a primary consideration. The digital workfl ow has improved the predictability and execution of implant therapy. It has also made it possible to increase accuracy, effi ciency, and patient comfort during treatment and to reliably achieve an esthetic result.

ABSTRACT

Introduction

Implant treatment is a reliable and predictable treatment for the

replacement of missing teeth,1,2,3 and demand for implant therapy

continues to increase. With precise planning and consideration of

all treatment aspects, implant-retained restorations have a good

prognosis, result in patient satisfaction, and do not involve adjacent

teeth.4,5 Subjective oral health improvement following single

implant treatment has also been found to improve, especially for

patients whose implants were placed in the anterior esthetic zone.6

Clinician and patient expectations dictate that treatment

planning consider anatomical, functional, and esthetic aspects of

implant therapy for the desired long-term outcomes. The maxillary

and mandibular anatomy at and adjacent to the proposed implant

site must be known. These will dictate the possible length of

implants, and whether ridge augmentation/bone grafting/sinus lift

is required to provide adequate bone height and volume. Buccal

and palatal/lingual resorption of the alveolar ridge and undercuts

can also result in the need for ridge augmentation, where defects

would otherwise result in perforation of the bony plate or poor

positioning of an implant.

Implants placed at an angle to compensate for inadequate bone

volume can also compromise clinical outcomes by causing abnormal

loading of the restored implant. This can increase bone loss beyond

that which is physiological, and can also result in mechanical failure

of the implant or restorative components. In addition, the implant

must be placed in a three-dimensional position that will allow for an

esthetic emergence profi le, peri-implant soft tissue development,

and a natural-looking defi nitive restoration. Factors infl uencing

patient satisfaction with esthetics include the color and shape of

the crown, and the amount of papillary fi ll.8 Treatment planning

must address implant position relative to the crestal bone and

buccal-lingual and mesio-distal dimensions, tissue type and volume,

development of the peri-implant tissue and achievement of papillary

fi ll, and the type of abutment and emergence profi le of the fi nal

restoration for an esthetic result. Digital treatment planning and the

digital workfl ow have improved the predictability and execution of

implant therapy, especially in the esthetic zone.

Digital Treatment Planning and the Digital Workfl owTraditionally, an initial patient assessment for implant therapy

included radiographs. However, radiographs do not provide a three-

dimensional (3D) view. Cone beam computed tomography (CBCT)

and computerized axial tomography (CAT), in addition to STL digital

scans/impressions, are now available and used to obtain 3D digital

images, with signifi cant improvements in planning and diagnostic

capabilities. Based on the risk of lingual plate perforation in the

posterior mandible, for instance, it was concluded that CBCT scanning

is essential for planning immediate implant placement.7 The implant

planning software creates virtual models to visualize a virtual implant

in the arch using 3D images and cross-sectional views captured using

the digital scans. The result is an overview of the ideal implant position

(Figure 1). 3D images and implant planning software show bone

defects where resorption has occurred, and show the clinician during

the treatment planning where insuffi cient bone volume is present and

where anatomical structures are in close proximity. In the example

shown, the patient had presented with generalized recession in the

region 5-12 and failing teeth #7 and 9, while periapical radiographs

revealed an apical bone defect in the area of tooth #7 and prior

apical surgery in teeth #7 and 9. The preoperative axial view sections

identifi ed a narrow/slender ridge and large nasopalatine duct. Teeth

#7 and 9 also appeared to have little/no overlying facial bone. The

unfavorable ridge anatomy and bone defects coupled with clinical

tissue challenges necessitated multistaged gingival tissue and bone

grafting procedures prior to implant placement (Figures 2, 3).

Due to the complexity of the case, bone grafting was fi rst

performed and the implant would be placed later. The digital

workfl ow continued with treatment planning of implants in sites #7

and 9, as shown by the Implant Studio screen capture of the axial

section. The implant at site #7 was shown planned approximately

1.5 mm from the adjacent root, but staying distal to the nasopalatine

canal (Figure 4). The planning of the precise implant position also

allowed for use of an angled screw channel for a defi nitive screw-

retained restoration. A new CBCT scan and optical scan were taken

5 months after bone grafting, and a screen capture of the virtual

tooth setup and position of implants respecting the adjacent roots

obtained (Figure 5). A palatal view screen capture showed the

planned implant and screw access positions. The digital workfl ow

enabled highly precise treatment planning for implant placement,

avoiding closely adjacent anatomical structures. In addition, virtual

implants, abutments, and restorations can be ‘placed’ to view

resulting emergence profi les and the restorative result.

The digital workfl ow also includes the creation of milled or

printed models, and printed surgical guides allow for precise creation

of osteotomies for implant placement, since the surgical guide’s

osteotomy window is printed based on the results from the implant

planning software. In addition to precision and the opportunity

to create custom healing abutments, the digital workfl ow offers

increased effi ciency and a better patient experience. For example,

scan fl ags and optical scanning can be used instead of using

traditional copings, impressions, and poured models with analogs. In

the case shown here, scan fl ags constructed of a titanium base and

PEEK (BioHorizons) were positioned over the implant and verifi ed

with radiographs to ensure they were properly seated (Figure 6).

Optical intraoral scans were then taken. These are interpreted by

CAD software, which creates a 3D digital model. The fi les can then be

transferred digitally to the laboratory for restoration fabrication, which

can be performed using the 3D digital model and CAD software, or a

milled/printed model for traditional restoration fabrication. Scan fl ags

enable high-precision intraoral optical scanning whereby the digital

images accurately record the implant fi xture, peri-implant mucosa,

and adjacent structures. As a result, effi ciency and accuracy are

greater, and the patient avoids a traditional impression.

Milled custom healing abutments and custom abutments are also

created using the digital workfl ow and CAD/CAM software, as well

as milled models for provisional fabrication and CAD/CAM or milled

models for fabrication of the defi nitive restoration (Figure 7).

The digital workfl ow has made implant treatment more precise and predictable, in addition to stream-lining treatment and improving overall effi ciency.

The case below demonstrates the digital workfl ow for single

implant therapy in the anterior esthetic zone.

Case 1. Single implant restoration replacing the upper left lateral incisor

incisor that was deemed hopeless (Figures 8, 9). Together with

DENTAL LEARNING

the patient, it was decided that the best option was extraction,

immediate implant placement, and temporization. Ideal planning

mandated the use of a CBCT scan. The digital workfl ow continued

with the use of implant planning software (3Shape) for assessment

of bone volume and quality, adjacent structures, and position of

a virtual implant. The initial planning was for immediate implant

placement of a 4.6 × 15 TLXP implant (BioHorizons) in order to

allow for apical bone engagement for primary implant stability.

However, using the implant planning software, the probability

of leaving less than 2 mm of facial bone was identifi ed (Figure

10). This would be undesirable and could result in future

postrestoration instability of the facial and gingival tissue, with

compromised esthetics. As a result, treatment was replanned for a

3.8 × 18 TLX implant (increased length, reduced diameter) (Figure

11). This would allow for primary implant stability, improved facial

bone volume for long-term tissue contour stability, and improved

positioning relative to the virtual tooth contour bucco-lingually.

After the ideal implant position was determined, the digital

workfl ow allowed for alignment and printing of a surgical

guide with inspection windows to verify full seating and color-

coding for the planned implant and incorporating sleeves

to aid precision during the osteotomy (Figure 12). Printed

surgical guides have been shown to have a high degree of

accuracy.9 Printed models were also created that would be

used to fabricate components for temporization. A broad

range of transitional restorative options can be preplanned

to adapt to the unique features of the clinical environment.

These include prefabricated, customized, healing abutments

that can be coupled with a bonded nano-ceramic or PMMA

bridge, and a transitional implant crown/engaging titanium

base and seating jig where stability and occlusion permit. While

engaging abutments are generally used in single restorations,

non-engaging bases can be used to allow for prefabricated

one-piece provisional restorations to overcome the problem of

vertical implant positioning (timing) in a guided protocol.

Customized healing abutments allow for ideal soft tissue

guidance and protection of underlying bone or bone graft

materials in immediate implant placement. Adjacent natural

teeth are predictive of papillary development and maintenance,

and the distance from the bone level to the contact point with

the adjacent tooth must be preplanned to foster papillary fill.10,11

Greater facial-lingual mucosal width at the base of the complete

papillae also results in more complete papillae. These factors

again highlight the desirability of precision planning, as offered

by the digital workflow.

In this case, a customized PMMA healing abutment on an

engaging titanium base was used that had been prefabricated

with 3D information from the STL and DICOM files taken at the

planning stage. The implant and healing abutment were verified

radiographically postsurgery, and a bonded bridge was used

for immediate temporization (Figures 13-15). Once peri-implant

soft tissue is subject to remodeling as with a custom healing

abutment/provisional restoration, it has been shown that papillae

will regenerate when both one-stage and two-stage surgical

protocols are maintained.12 Conservative surgical treatment was

possible (extraction, implant placement, and bone grafting of the

facial residual horizontal bone defect, custom healing abutment),

resulting in uneventful soft tissue healing.

After soft tissue remodeling, the tissue contour was ideal,

and a custom zirconia abutment was digitally designed and

milled. Custom zirconia abutments result in superior esthetics

and avoid the gray shine-through of metal abutments that may

be observed at gingival margins. The margin was also designed

to be 0.5 mm subgingival to mirror the marginal gingival tissue

defined by the healing abutment. A screw-retained lithium

disilicate crown was milled from a digital model, and placed

(Figures 16, 17). The result was an esthetic restoration that

mimicked nature, and a satisfied patient.

ConclusionsImplant therapy is now mainstream and frequently the

treatment of choice. In the anterior esthetic zone, the emergence

profile must allow for excellent esthetics, and the final restoration

must mimic (or improve on) nature in addition to being functional.

The advent of CBCT scans, digital impressions and the digital

workflow has made treatment more precise and predictable.

Virtual implant planning supports a restorative-driven approach

with improved esthetics and function.13, 14 The digital workflow

also streamlines treatment with fewer appointments, and is more

efficient overall, resulting in time and cost savings.15 It also allows

the clinician and laboratory technician to share the same 3D

images and treatment planning tools, improving communication,

planning, and actual treatment.

For the patient, the office is seen as high-tech, treatment

is easier (e.g., scan flags and scanning remove the need for

unpleasant traditional impressions and are quicker), and

customized CAD/CAM components result in excellent esthetics.

In summary, the digital workflow provides predictability,

precision, efficiency, and a great patient experience.
