Intraoral
scanner.

An intraoral scanner is a device that optically captures the surface information of teeth and accessible soft tissues inside the mouth. The pen-shaped scanner tip is guided over and around the teeth in a specific sequence by the dentist. The images captured by the device are stitched together by software to create a three-dimensional oral model on the screen. This model can be used to evaluate tooth shape, contacts with adjacent teeth, gum margins, and upper-lower jaw relationships. Scanning does not involve waiting for traditional impression materials to set. The resulting record can be magnified within the same appointment, examined from different angles, and if a small area appears missing, only that section can be rescanned.

A digital impression is not a treatment on its own; it is a recording method that provides data for planning and production. Its area of application varies depending on the procedure. It can be evaluated in processes such as crowns, bridges, veneers, implant-supported restorations, clear aligners, night guards, or monitoring the current oral condition. Visibility of the gum margin, intraoral moisture, bleeding, mouth opening, and the location of the area to be scanned can affect the quality of the record. Therefore, intraoral conditions are inspected prior to scanning and necessary preparations are made. While intraoral scanners are actively used in our clinic, whether a digital impression is sufficient for a specific procedure is determined through clinical evaluation for each patient. In some cases, a different impression method or additional records may be required.

In conventional impression methods, impression material is placed in the mouth within a tray and held for a certain period for the material to set. As the tray approaches the palate, tongue base, or back of the mouth, it can trigger a gag reflex in some individuals. Intraoral scanning does not use large impression trays or fluid impression materials. The pen-shaped scanner tip is moved in sections within the mouth. This way of working can facilitate managing the impression stage, especially for individuals experiencing nausea or gagging related to the presence of impression material. Short breaks can be taken if necessary, scanning can resume from where it left off, and work can be performed solely on the area requiring recording.

However, it cannot be claimed that digital scanning will completely eliminate the gag reflex in every person. The intensity of the reflex varies depending on the location of contact in the mouth, anxiety levels, breathing patterns, existing stomach or throat sensitivity, and personal tolerance. The scanner tip reaching posterior areas may still trigger the reflex in some individuals. Therefore, sharing previous experiences with the dentist before the procedure is important. Regular nasal breathing during scanning, adjusting head position, taking breaks between sections, and progressing the recording in a controlled manner can be helpful. In our clinic, the process is conducted while observing individual tolerance. The goal is not to promise absolute comfort, but to evaluate a digital recording option that eliminates stimuli caused by impression trays and materials within clinical suitability.

An intraoral scanner can be evaluated as a recording tool in many dental procedures requiring surface impressions. In fixed prosthodontics, prepared teeth, adjacent teeth, and the opposing arch can be recorded for planning restorations such as crowns, bridges, veneers, inlays, onlays, and endocrowns. In implant-supported restorations, appropriate scan bodies can be used to transfer the intraoral position of the implant to a digital model. In orthodontic evaluations, tooth alignment and bite can be recorded; it can be used to plan custom appliances like clear aligners or retention appliances. Digital models can also be utilized in fabricating night guards, protective appliances, and certain temporary restorations.

The scanner is not used solely for sending data to production. It can also create records for archiving pre-treatment oral conditions, comparing changes over time, and discussing the plan with the patient on-screen. However, not every clinical situation can be resolved with the same scanning method. Deep subgingival margins, uncontrollable bleeding or moisture, limited mouth opening, large areas of mobile tissue, and certain completely edentulous cases may require additional methods. Furthermore, intraoral scanning does not show the jawbone or internal structures of tooth roots; thus, it does not replace X-rays or 3D radiological imaging. Which records are necessary is determined according to the scope of treatment to be performed. In our clinic, scanners are used actively; method selection is made based on clinical necessity and the data required, not merely the presence of the device.

Digital impressions can contribute to time savings in certain workflows; however, no guarantee can be given that they will alter the overall treatment duration equally for every case. Because the model generated during scanning is immediately visible on screen, the record can be inspected while the patient is still in the clinic. If a small missing or unclear area is noticed, only that section can be rescanned instead of taking the entire impression from scratch. When the approved file can be transmitted electronically to a compatible laboratory system, intermediate steps such as packaging physical impressions, shipping, and pouring plaster models in the lab may be eliminated. This can help start the data flow between clinic and laboratory on the same day.

The total schedule still depends on the type of restoration, tooth and gum conditions, laboratory production plans, try-in needs, materials used, and potential adjustments required during treatment. For example, sending a digital file electronically does not automatically alter the time required for ceramic preparation or biological healing. Bone and soft tissue healing in implant procedures remain a separate part of the clinical timeline. Try-ins and bite checks may still be necessary in crown or veneer procedures. Therefore, promising “same-day delivery” or completion within a specific timeframe is not accurate. In our clinic, digital recording is actively used to reduce re-impression risks, inspect data without delay, and initiate the appropriate laboratory process. Estimated timelines for patients can only be shared after examination, treatment planning, and laboratory requirements are established.

When a digital impression is approved, the 3D record can be transmitted to the laboratory workflow in a secure file format. Laboratory technicians can review prepared teeth, adjacent contacts, opposing arches, and bite records within software. Stages such as disinfection, packaging, transportation, plaster pouring, and waiting for model setting required for physical impressions may not exist in digital workflows. If an area in the file is unclear or requires clarification, early communication can be established between clinic and lab. Thus, record adequacy can be evaluated before production starts, and if needed, rescanning a limited region can be requested.

This mode of transfer does not automatically shorten every laboratory process. Design preparation, material selection, production, staining, surface treatments, and quality control require time according to the restoration being made. Compatibility of the lab system with digital files and complete transmission of clinical details are also essential. Shade selection, photos, bite information, or practitioner technical notes may not be derived solely from 3D models; these are shared separately. In some procedures, printing physical models or performing try-ins may still be preferred. In our clinic, records obtained from intraoral scanners are sent electronically to the lab in suitable cases. The goal is to provide the laboratory with timely access to clinical data and evaluate impression suitability early. Delivery dates are determined considering restoration scope, lab schedule, and clinical checks together.

Preparing a tooth for a crown, veneer, inlay, or onlay is a clinical procedure conducted according to the amount of decay, existing fillings, tooth position, planned restoration, and preserving healthy tissue. An intraoral scanner does not prepare the tooth on its own and does not alter the biological or mechanical rules required for preparation. However, inspecting the surface enlarged on screen after preparation is complete can help the dentist verify finish lines and scannable areas in the same session. If an unclear section is noticed, soft tissue or moisture control can be adjusted and only that area rescanned. This feedback allows handling potential recording issues while the patient is still in the chair.

Therefore, if time is saved, it stems mostly from managing control and impression steps within the same digital workflow rather than speeding up the preparation itself. The time required for revealing finish lines, controlling bleeding, cleaning caries, and preserving healthy tissue cannot be skipped. Proceeding to scanning without completing clinical requirements can lower record quality and lead to re-treatment needs. In our clinic, scanning is performed after preparation is finished and the recording area is made suitable. The model is checked on screen; necessary areas are rescanned, and the lab phase is initiated only when adequate records are obtained. The date the patient receives their restoration depends not just on scanning time, but on the restoration being made, try-in needs, lab manufacturing, and oral tissue conditions.

One working feature of intraoral scanning is the real-time viewing of records on screen. Once scanning is complete, the model can be rotated and magnified from various angles. The dentist checks tooth surfaces, preparation margins, adjacent contacts, gum margins, and bite registration. If a small section highlighted by software or visual inspection is missing, deleting the entire record is usually unnecessary. The relevant area is imaged again, and new data is stitched into the existing model. This approach can reduce the need to repeat entire impressions due to voids or distortions noticed later in conventional material impressions.

Still, not every flaw can be corrected through local rescanning. If systematic distortion exists throughout the recording, scan sequence was lost, mobile tissues impacted the model, or bite alignment failed to match correctly, a larger section may need to be retaken. Rescanning without correcting intraoral conditions like bleeding, saliva, or hidden gum margins may not yield adequate results. Therefore, the cause of deficiency is identified first, the area is prepared, and the record is renewed. In our clinic, files are reviewed on screen before being sent to the lab. Digital checks do not mean errors will never occur; they help identify visible issues early. Further information or new records may also be requested during lab review. The goal is to generate a usable dataset aligned with clinical planning before production begins.

Intraoral scanning is a procedure where surfaces are optically recorded; the device does not cut, abrade, or treat tissue with radiation. The scanner tip is moved in a controlled manner around the teeth, and gentle retraction of the cheek or tongue may be needed in certain areas. Thus, the procedure is not painful for most individuals. However, people with sensitive gums, recent surgical sites, mouth sores, limited mouth opening, or jaw joint complaints may feel discomfort from contact or holding the mouth open. Informing the dentist of existing sensitivities or recent procedures beforehand helps tailor the process accordingly.

Maintaining a clear field of view during scanning is important. Saliva and moisture are managed when necessary; cheeks, lips, and tongue are safely controlled. The scanner tip is prepared in compliance with manufacturer instructions and infection control protocols. If the individual feels fatigued, nauseous, or wishes to pause, scanning can be stopped and resumed from an appropriate point. Tissue management methods used to expose deep preparation margins are separate clinical procedures from scanning itself and may cause sensitivity depending on the individual. Intraoral scanners are actively used in our clinic; procedure duration varies according to the area scanned and intraoral conditions. Any pain, significant discomfort, or difficulty breathing felt during the procedure should be communicated to the dentist immediately.

An intraoral scanner and X-rays record different information. The scanner converts light reflections off surfaces into a 3D model of outer tooth forms and visible soft tissues. It does not display internal structures of jawbones, tooth roots, root canals, impacted teeth, or decay beneath surfaces. Therefore, if radiographic examination is needed in diagnosis and treatment planning, intraoral scanning cannot replace it. The need for panoramic films, periapical films, or 3D radiological imaging is evaluated separately based on clinical findings and planned procedures. Scanning and radiography can serve as complementary records within the same plan.

Digital impressions are also not an unconditional substitute for all conventional impressions. They can be used in many fixed restoration procedures where teeth are present and margins are visible. However, very deep subgingival margins, uncontrollable bleeding, extensive mobile soft tissue areas, certain completely edentulous cases, or oral conditions limiting device access may require a different recording method. Sometimes digital and conventional records are combined. Method selection is made considering data required by the lab, the restoration to be made, and intraoral conditions—not solely based on patient preference or device availability. Intraoral scanners are actively used in our clinic, and the impression method for each case is established prior to the procedure. Alternative impression approaches are explained to the patient if digital methods are unsuitable.

In our clinic, intraoral scanners are used actively in cases where digital recording contributes to planning or producing the relevant treatment. The process begins with a clinical examination. The type of procedure, scan area, condition of gums and tooth surfaces, mouth opening, and necessary additional records are determined. Surfaces are cleaned before scanning; saliva, moisture, or bleeding affecting visibility are controlled. If tooth preparation was performed for restorations, margins are made visible. Lower jaw, upper jaw, and bite relationships are recorded in a specific order. The 3D model is reviewed while the patient is in the chair, and necessary areas are rescanned.

Once the record is approved, its intended use varies by treatment. The file can be saved for planning, compared with previous records, or transmitted electronically to the laboratory for restoration preparation. Necessary notes regarding restoration type, material, shade, bite, and clinical expectations are attached to files sent to the lab. Digital transmission can reduce certain intermediate steps; however, production, try-ins, clinical fit, and delivery checks continue. Using a scanner does not guarantee a specific delivery date or treatment outcome. Treatment schedules, biological conditions, and lab procedures are evaluated together. Patient digital records are considered health data; storage and sharing processes must be conducted per relevant privacy rules. Special preparation before appointments is usually unnecessary; gag reflexes, jaw opening difficulties, or previous impression experiences should be discussed with the dentist during examination.
