Digital Dentistry

Digital dentistry is an approach that uses digital technologies during examination, record-taking, treatment planning, design, and production. It does not refer to a single specific treatment. Intraoral scanning, digital smile design, CAD/CAM restoration production, implant planning, orthodontic modeling, and three-dimensional radiographic imaging are different components of this approach.

Digital systems can help evaluate oral structures using measurable data and support more organized information transfer between the patient, dentist, and laboratory. However, technology alone does not guarantee treatment success. The outcome depends on many factors, including accurate diagnosis, appropriate material selection, dentist experience, production quality, and clinical application.

At ON7 Clinic, digital technologies are not automatically used in the same way for every treatment. Depending on the patient’s needs, appropriate technologies such as intraoral scanning, three-dimensional imaging, computer-aided design, or digital production can be incorporated into the treatment plan.

What Is Digital Dentistry?

Digital dentistry is not a single treatment method that replaces traditional dentistry; rather, it is a technological workflow that supports conventional dental procedures.

With these systems, the patient’s teeth and intraoral surfaces can be digitally recorded, the collected data can be examined using computer software, and, when appropriate, used to design restorations. In areas such as implant surgery, aesthetic dentistry, and orthodontics, different types of digital data can be combined to enable more detailed treatment planning.

One of the most important contributions of digital dentistry is the ability to record data from different stages of treatment and reassess it when necessary. However, digital records may also have limitations caused by incomplete scanning, movement, saliva, bleeding, or software-related issues. Therefore, all digital data should be interpreted together with a clinical examination.

What Technologies Are Used in Digital Dentistry?

The technologies used in digital dentistry do not produce the same type of information. An intraoral scanner creates a surface model, while CBCT provides radiographic information about the bone and teeth. Photographs and facial scans can be used to evaluate external appearance, lip movements, and the relationship between facial structures and the smile.

Intraoral Scanners

Intraoral scanners capture optical images of the teeth and visible soft tissues within the scanner’s field of view to create a three-dimensional digital model.

In suitable cases, they can allow dental records to be obtained without traditional impression materials and trays. This can be more comfortable for patients who experience a gag reflex or discomfort with conventional impression materials.

A scanner can only record surfaces that it can see. It does not show the underlying bone structure. Deep subgingival margins, bleeding, excessive saliva, limited mouth opening, or extensive full-arch scans can affect recording quality. When necessary, conventional impressions or hybrid methods may be used.

CAD/CAM Design and Manufacturing

CAD stands for computer-aided design, while CAM stands for computer-aided manufacturing. These systems can be used to design and manufacture porcelain veneers, crowns, bridges, inlays, onlays, and certain implant-supported restorations.

Data obtained from a digital scan is transferred to design software. The shape of the restoration, its contacts with neighboring teeth, and its relationship with the opposing jaw can be evaluated digitally. The design can then be converted into a physical restoration through milling or other manufacturing methods.

CAD/CAM systems can support the production of restorations that are appropriate for the selected material and clinical conditions. However, the lifespan of a restoration does not depend solely on digital production. Remaining tooth structure, bonding procedures, bite forces, teeth grinding, oral hygiene, and manufacturing quality can also affect the outcome.

3D Imaging with CBCT

Cone beam computed tomography (CBCT) can create three-dimensional radiographic images of the teeth, jawbone, and surrounding anatomical structures.

CBCT may be used particularly for implant planning, impacted teeth, certain surgical procedures, and evaluation of bone structure. Unlike an intraoral scanner, CBCT does not primarily capture surface anatomy; it provides radiographic information about teeth and bone structures.

Three-dimensional imaging is not routinely required for every patient. It should be used when the clinical information it provides justifies the radiation exposure and is necessary for treatment planning.

Digital Smile Design

Digital smile design helps evaluate the proposed shape, size, and proportions of teeth using photographs and digital models.

During this stage, the relationship between the teeth and the face, lips, and smile line can be assessed. The patient and dentist can discuss proposed changes using the same visual representation.

The design displayed on a screen does not guarantee the final result exactly. Gum structure, existing tooth tissue, bite, material properties, and biological limitations can affect the clinical outcome. When appropriate, the digital design can also be evaluated intraorally using a mock-up.

Guided Implant Planning

During implant planning, CBCT data can be combined with intraoral scan data. This allows the planned position of the implant within the bone to be evaluated together with the position of the future prosthesis.

In suitable cases, a surgical guide can be designed to support implant placement at the planned angle and location. A surgical guide does not replace the dentist’s clinical assessment and is not necessary for every implant case.

Which Treatments Use Digital Dentistry?

Digital technologies can be used in many dental procedures. However, not every treatment can or needs to be performed entirely digitally.

Porcelain Veneers, Crowns, and Bridges

Digital impressions can be obtained using intraoral scanning when planning porcelain veneers, crowns, and bridges. The resulting records can be used for restoration design and communication with the dental laboratory.

The shape of the restoration, contact areas with neighboring teeth, and bite relationship with the opposing jaw can be evaluated during the design process. Nevertheless, marginal fit, contact points, color, and occlusion must be clinically checked before the restoration is placed.

Implant-Supported Prostheses

Digital impression and design systems can be used for single implant-supported crowns, implant-supported bridges, and more extensive prosthetic treatments.

Digital records can help transfer implant positions to the laboratory and support prosthetic planning. However, in extensive treatments such as full-arch implant-supported prostheses, scanning accuracy can vary depending on the system used and clinical conditions. In some cases, conventional verification methods or physical try-ins may still be necessary.

Smile Design

In smile design, photographs, intraoral scans, and, when necessary, facial records can be evaluated together. This allows proposed tooth shapes, gum levels, and smile lines to be discussed more clearly with the patient.

Digital planning alone does not determine which treatment should be performed. Teeth whitening, bonding, veneers, orthodontics, or gum procedures should each be evaluated according to the patient’s clinical needs.

Orthodontic Records and Planning

Intraoral scanners can create digital dental models for orthodontic treatment. These models can be used to examine tooth positions, plan clear aligner treatments, and monitor treatment progress.

Digital simulations can help plan tooth movement; however, the rate of biological tooth movement and the treatment outcome can vary from patient to patient.

Implant Surgery Planning

Three-dimensional bone images, intraoral scans, and the prosthetic plan can be evaluated together during implant treatment. This approach helps plan not only the position of the implant within the bone but also the appropriate position of the future tooth.

Same-day temporary teeth or immediate loading may be considered only when suitable bone structure, sufficient implant stability, and appropriate clinical conditions are present. Digital planning does not mean that permanent teeth will be completed on the same day for every patient.

How Does the Digital Dentistry Process Work?

The digital workflow varies depending on the treatment being performed. A simple crown treatment does not involve the same stages as implant surgery or comprehensive smile design.

Digital Records and Scanning

The first stage is a clinical examination. When necessary, photographs, intraoral scans, or radiographic images are obtained.

During an intraoral scan, the device records the surfaces of the teeth and visible soft tissues. Areas that were not adequately captured can be rescanned. If bleeding or saliva affects the quality of the recording, the working area should first be controlled.

Computer-Aided Treatment Planning

The collected data is evaluated using software according to the treatment objective. For restorations, tooth shape and occlusion are assessed; for implant planning, bone structure and prosthetic position are evaluated; and for smile design, the relationship between the face and lips is considered.

Digital systems support the evaluation of aesthetic and functional treatment plans using digital models. The final decision is still based on clinical examination and the dentist’s professional assessment.

CAD/CAM Manufacturing

The planned restoration can be manufactured using CAD/CAM systems either within the clinic or in a dental laboratory.

Production time varies depending on the material, restoration type, and workflow of the clinic. Some simple restorations can be manufactured on the same day, while procedures requiring aesthetic layering, laboratory quality control, or multiple try-ins may take longer.

Clinical Try-In and Placement

A digitally designed restoration should not be placed without clinical verification. It is tried on the tooth to evaluate marginal fit, contact with neighboring teeth, occlusion, color, and aesthetic appearance.

Once the necessary adjustments have been completed, the restoration is bonded or fixed using the appropriate method. A digital workflow may help reduce certain sources of error, but it does not eliminate the need for clinical evaluation.

What Is the Difference Between Digital and Traditional Dental Impressions?

Both digital and traditional impression techniques can be used clinically with the correct technique and appropriate case selection. It would not be accurate to say that one method is superior to the other in every situation.

Digital impressions can provide an efficient workflow, particularly for limited restorations and suitable oral conditions. For deep subgingival margins, extensive implant-supported treatments, or difficult-to-access areas, traditional or hybrid impression methods may be preferred.

Is Digital Scanning Painful?

Intraoral digital scanning is a non-surgical recording method and generally does not require anesthesia. The scanner tip is moved around the teeth to capture digital images.

Many patients may find digital scanning more comfortable than traditional impression materials. However, temporary discomfort may occur in patients with limited mouth opening, sensitive teeth, a strong gag reflex, or difficulty reaching posterior areas with the scanner.

The fact that digital scanning is generally painless does not mean that all treatments planned digitally are painless. Procedures such as crown preparation, implant surgery, or gum treatments may require local anesthesia.

Can Digital Dental Treatments Be Completed on the Same Day?

Some restorative procedures can be completed on the same day when in-house CAD/CAM manufacturing and suitable materials are available. For example, certain inlay, onlay, or single-crown treatments can involve scanning, design, manufacturing, and bonding within the same day.

However, same-day treatment is not suitable for every procedure. Porcelain veneers, multi-unit bridges, comprehensive smile designs, implant-supported prostheses, and restorations requiring extensive laboratory work may require multiple appointments.

Digital data transfer and manufacturing can help improve the efficiency of laboratory and clinical workflows for suitable treatments. However, treatment duration should be determined primarily by clinical requirements rather than the patient’s expectation of speed.

What Are the Advantages of Digital Dentistry?

The advantages provided by digital technologies vary depending on the system used and the type of treatment. One of the most notable benefits of intraoral scanning is that it provides an alternative recording method to traditional impression materials. The ability to rescan incomplete areas and digitally transfer data to the laboratory can simplify the workflow.

Digital design can support communication between the dentist and dental laboratory. The shape of the restoration, contact areas, and occlusion can be evaluated during the design process. In smile design, patients can also visually evaluate proposed changes before treatment begins.

The ability to store digital records can also help compare the condition before and after treatment. Orthodontic monitoring, tracking tooth wear, and evaluating changes in existing restorations over time are examples of this use.

These advantages do not completely eliminate the possibility of errors. Digital data must be captured correctly, interpreted appropriately, and accurately transferred into clinical treatment.

What Are the Limitations of Digital Dentistry?

Although digital systems support many dental procedures, not every treatment can be performed entirely digitally, and not every procedure can be completed in a single appointment.

Intraoral scanners record only surfaces that can be captured optically. Deep subgingival margins, bleeding, saliva, and movement can affect image quality. In extensive full-arch or multiple-implant scans, cumulative deviations may occur.

Digital design can help evaluate a potential outcome, but it cannot precisely predict how biological tissues will respond to treatment. Differences between the digital design and final restoration may occur because of material properties, manufacturing processes, and clinical conditions.

Traditional impressions, physical models, try-ins, or laboratory procedures may still be necessary for certain treatments. Advanced equipment or software alone cannot guarantee clinical success when diagnosis or treatment selection is inappropriate.

Three-dimensional imaging should also not be used routinely for every patient. CBCT should be considered when it is expected to provide meaningful information for treatment planning.

What Should Be Considered After Digital Dental Treatments?

The care required for digitally planned or digitally manufactured restorations is not fundamentally different from the care required for comparable traditional restorations. Crowns, bridges, veneers, and implant-supported prostheses require regular oral hygiene and clinical monitoring.

Brushing twice a day with an appropriate technique and cleaning between the teeth with dental floss or interdental brushes is important. Particular attention should be paid to areas beneath bridges, around implants, and along restoration margins where plaque may accumulate.

The fit of restoration margins and surface quality can influence oral hygiene. However, plaque accumulation is primarily related to restoration design, surface characteristics, the relationship with the gums, and the individual’s cleaning habits.

Patients who grind or clench their teeth may have an increased risk of restoration wear or fracture. If necessary, the dentist may recommend a night guard.

Antiseptic mouthwash should not routinely be used continuously by everyone. If considered necessary by the dentist, specific products may be recommended for a limited period.

The frequency of check-ups is determined according to the treatment performed, gum health, caries risk, presence of implants, and oral hygiene status. Regular check-ups can help identify potential problems affecting restorations or surrounding tissues at an early stage.

Digital Dentistry Approach at ON7 Clinic

At ON7 Clinic, digital dentistry is not approached as a standardized system in which the same technology or method is automatically applied to every patient. First, the patient’s treatment needs are determined, and then the stages in which digital technologies may provide value are evaluated.

In suitable cases, digital impressions can be obtained using intraoral scanners, restorations can be designed using CAD/CAM systems, and three-dimensional imaging can be incorporated into implant or surgical planning. In aesthetic treatments, digital smile design can be used to support communication between the patient and dentist regarding the proposed treatment design.

Not every treatment needs to be completely digital. In some cases, a hybrid workflow combining digital and traditional methods can provide a more appropriate treatment process.

At ON7 Clinic, digital data is used to support, rather than replace, clinical examination and treatment planning. Once restorations have been manufactured, their fit, occlusion, contact points, and aesthetic appearance are clinically evaluated in the patient’s mouth.

The goal is not to present technology as an advantage on its own, but to use the appropriate technology at the appropriate stage for the right patient in order to support treatment communication, record-taking, and clinical planning.
